Number 1 to the light emitting surface closure defined by rear view of the reference Image receiver (28), is captured by (step 102). During the process later Image said reference the memory for (82) are stored in.

Master (32) is number 1 light emitting surface (24) is disposed on a housing (22) when door of, confirming is the starting process. Frame (38) a high density impurity ions are implanted (32) receiver (28). located within an area a viewing end and an output end. Door confirming process material is started or when user button (36) one confirming by pressing an. process may be initiated.

Control master of a device 2 captures an Image. Number 1 for the, control device number 1 only the user's machine to operate and only light emitting surface, is are irradiated a rear view is master key. Receiver captured inspection Image rear view of master key (step 104), said Image memory (82) are stored in. Number 2 for the, number 1 and number 2 is a control unit controls light emitting surface, is master key (32) unsupported upper surface radiation or surface thereof, and the are irradiated a. Receiver captured inspection Image upper surface of master key (step 106), said Image memory (82) are stored in.

Alternatively, the, control device a rear view without capture of inspection Image upper surface of master only inspection Image capture may be filled in the space. 14a detailed in the following, key Image an upper surface inspection Image can be ascertained based on only. However, 14a detailed in the following in addition, a master key based on inspection Image rear view comparing the publicly known key blanks top inspection Image rather than around the detected interior angle can be performed more expeditiously. Therefore, the information obtained from the inspection Image rear view an upper surface inspection Image for the information obtained from the key blank some prior to comparing enhance to speed process confirming is coupled to the upper end.

Preferably, device control then generates Image's silhouette master key (step 108). Rear view of master key is initial inspection Image removing reference Image captured during the process (subtract) can be is obtained by. Said result is silhouette Image of master key.

And, control device for analysing the Image, silhouette of a key that edge of the master form map (step 110). Edge map a high density impurity ions are implanted edges of hence a different points of the relative positions of the array of point to multi-point defined and which is. Edge map memory for subsequent processing (82) are stored in. During the process said, control device (extreme point) in determining the presence of a reversal map edge in addition, most of the Image, or a extrema said left and most right, optimum and bottom points is.

And, control device said point with direct proximity of edge map by analyzing a key head (64) and tip (62) and decides the indicating the points at which the. Key head (64) and tip (62) the system is moved, number 1 light emitting surface (24) of the master (step 112). it is then possible.

And, control device a key blade edge of recognition key cross section of the key analysis map both sides. decide if a key (step 113). Control device indicative of a key blade both sides of inspection the edge map. A distance control device that is able to determine the spots. 2, having a ramp between spots. 2 calculates a. Is a reference warp (reference slope) is. Furthermore, control device an endpoint the other point to migrate to and close to the new point. the inclination at locations. Said process few-time repeated and then, the newly calculated each case compared with warp yarns and weft reference slope. New reference the cervical region of the spine calculated whenever the mobile station exits the error of warp ends, this is count as a dispersion of warp ends. If, or not the counter is equal to for making the exceeds a certain limits, key blade aspect which allows surface cut is. Said process, control device blades in one aspect or at both sides are cut surface of having (i.e., recognition key both sides or key cross section) unit..

Furthermore, control device an edge from maps (spine) spine key shoulder and extracts location information of master (step 114) (32). (L) of blade length. In key cross section key is not cut is spine. Control device present near the particle sensor each other first-surface not cut that is able to determine the spots. 2, said 2 calculates a having a ramp between spots.. Furthermore, control edge is not the cutting device key along edge of key a contact hole is formed by retrieving the map sets the tip end of the spine, reference-surface not cut avoid changing of the ramped warp finds point. Furthermore, control device is not the cutting edge along edge of key toward the head of key by retrieving the map sets the end head of spine, reference-surface not cut avoid changing of the ramped warp finds point. Said. sets blade length maximum in addition process.

Furthermore, control device retrieves a shoulder with respect to a corresponding. The blade lengths of cutting on the surface with a spine perpendicular on the head end of is made by locating point. Cut key edge cut be sloped toward the edge not indicative of the degree an inclined deviation for, vertical said device are controlled from point the cutting the solder resist layer toward an end tip of a key that a blade rear surface of the edge map retrieves. If said condition of constant a within searched, head frame previously identified spine of a key that a shoulder point (71) is the layout based upon the resistance value. However, if significant upon detection of deviation warp of a value, said deviation not cut perpendicular to the spine point surface a shoulder point (71) is interpreted to into. Control device a spark-between a tip and a shoulder spine calculates a (L) blade length as distances between.

In key both sides, blade lengths of cutting in the uncovered part of the both sides of the blade relative to the one point by placing key spine is identified. Furthermore, a proximal system/down key blade area between can be assumed a straight head. Straight system also determines a range between centerline or center point of the rudder. for identifying. And, tip end of the key system the key retrieved from finds the points on the centerline of. In the uncovered part of the lengths of cutting blade key/down key centerline key between end is a double-sided key spine.

When simply, both sides opening or closing display unit in the cut one aspect of key can be, not cut another aspect can be an opening or closing display unit in. Both sides key shoulder point (71) in the cross-section is determined in a manner similar to key. Both sides key blade length (L) has a shoulder point (71) and key tip (62). is the distance between the edges of.

Preferably, in a database system to manually search the publicly known key blanks different number of cut edge (i.e., master unlicensed key cross section is unlicensed key both sides) has a predetermined blade length of master error like a cylinder type structure having blade length removing the key blank. Potential elements of the matched result of additional subset is maintained in memory for comparison..

Furthermore, system head and shoulder information about the shape are determined from the extracted area (step 116). Master shoulder and head end of the key head geometries in between connection point and of heads series of indexed positions is shaped by applying. System (extrapolation) extrapolation and interpolation (interpolation) certain diversification in that shape to accommodate compact head through. smoothing. Preferably, master head geometries in results to a future information simplify the configuration of the matching process information about the shape to reduce the strength is integrated. Data group are of the same size continuous widths width and width (length) a count is generated indicative of a single width couple the described is integrated through. Such groove to the width of the central as one shape described is coupled string. Publicly known key blanks with this binder step which is compared against a head for the shape. reduce the amount of data.

And, controller and the remaining filter blade length and cut edge a match of list at compares a information shoulder and the head. Preferably, control device first sidewalls of match the key blank potential is capable of being isolated from head geometries master to perform a comparison, may fall within a predetermined error like a cylinder type structure removing the key blanks.

The configuration compared master key string described a shape for each width description publicly known key blanks is process comparing the description of. Preferably, the respective comparison the likeness marks is assigned to. If, after are compared string shape described publicly known or master any key blank may be disabled if the remaining description is width, compared, resulting low thus score. A comparison process said width and said width locations on the air must considers both. Said process advantage of both symmetrical and non-symmetric key can be-uniquely identify is.

Preferably, control device a similar to one another maintains information for a the key blanks. Master match of possible to whenever list is created, control device the identified key blanks on a list each analogous to the blank and other key the free surfaces lists are created. If a match, identified as potential blank is one or more of the keys on a list elements of the matched analogous to the blank and other key had not been overridden is created list, updates the information along said system.. Control device key blank reliably device cannot confirm it may be an, similar to master an appropriate keys used to confirm the key blanks can be user.

The most similar each other in addition system for identifying key blanks using (ranking system) ranking system may be loaded with. Keys are is each similarity and evaluates it with regard to stored with said information to the key blank information can be is obtained by. The key blank is fully reliably until the check that the, which is assigned at a match list of similarity ranking can be user according to.

And, the result of comparison of control device a head and shoulder shape as possible in the analysis the key blank remaining match (step 120). Also now a longitude 10b.. If match list without, i.e. match is coated on an alloy without the key blank is extracted from the injection molding, a device control "no is matching key database" for an appropriate message such as LCD display (34). display on (step 122). If only one key blanks a match as checked (step 124), said key blank master key is key blank corresponding to. Control device matched to the user skin tones in order to identify a key blanks LCD display (34) on. to display messages (step 128).

If multiple key is likely if identified as a match, control device upper surface of master key are determined from the extracted area shape outlet milling from inspection Image (step 126). An upper surface is removed to a reference Image from inspection Image master a unsupported (exposed) surface of produce an Image obtained by means of a. Control of master key device analyzes pixel of an Image said milling outlet shape (76) identifying a. Also 11a to 11d as shown in also, milling outlet shape (76) a milling the key blade a position indicative of line key in "shape (shape string) string" as identified. Control device a key blade color gray of an Image on a milling by normalizing an outlet shape (76) of "shape string" can be-definable structure that is adding. The shadow-excited gray value-to conform to the gray value a stationary seal ring can be done by varying the.. Said device is a control process to further facilitate milling edge and shadow milling confirms a..

Preferably, milling outlet pattern (76) the (, as determined on) position of spine is definable associated with the warp yarns and weft. Master the following string formed shape on the orientation in one direction is to be direction : (1) a direction parallel to spine, (2) spine a direction perpendicular to (3) is inclined from a spine a direction inclined with phosphorous in the or spa a direction. Therefore, outlet-shaped shaped edges a milling string shape a segment, position and indicative of a direction or the data set of vectors is defined by a group.

And, control device a milling outlet group data defining a string shape publicly known key blanks of milling outlet shape defining a string compares a group and the stored data (step 130). Milling outlet head geometries comparison similar comparison process is carried out in method. Control device master key descriptor shape mill of publicly known key blank milling shape descriptors and each scoring the comparison result. Certain limits a match a score value quantized values that exceed the hose in the shape can be non-volatile memory elements is considered. Preferably, this time-consuming compared in the previous comparison process identified as a match likely subset of key blanks is carried out on. However, this search the total data blank the publicly known key can be exist on the base. Each air conditioner has a drain discharge system, milling outlet-shaped the result of the comparison will likely identified as a match list of key blanks is would reduce the.

If, only one, identified as an if match is key blanks (step 132), said key blank master key is key blank corresponding to. Furthermore, control device a LCD display (34) key blank a displayed to the user the identification announcement matching (step 128).

However, if a match likely remains key blanks on a list if at least two, opposing sides of master is to be tested should (step 134). A match likely to master a key remaining opposing sides of the key blank blank the key blank between additionally having milling to improve that can be distinguished is analyzed to to determine whether or not. Key the key blank remaining if additional opposite side by milling if not distinguish the longer, and reaches only process confirming, control device a match as a likely remaining each key blank LCD display (34) through (step 136) which assures a user that the to.

Control device in a variety of method of master useful on the opposite side of the yarn to determine whether or not information is present, and can be. For example, specific key data information about the blank when indicator (indicator) is stored in the database will receives and stores the updated. Includes the information for the key blanks, when loaded, key blank is unique both sides a milling pattern is determined whether. If, preserved within a database is and signal lines and performs display according indicator. Control device said indicator the key for additional flip in order to obtain information on and decides the whether must be (flip).

Alternatively, the, control device key blank milling against the sides opposite the inspection string shape. Said opposing sides of the key blank comparison determines whether a different. If, on the other side of the key blanks different milling pattern is located on a surface of different point if there is, the key blank between a distinction is made, the invention relates to a process must, key in order to obtain information on additional flip, and the postfiltering must be.. If, the key blank, on opposing sides of different point unless there is not, additional flip of the keys analysis, and. not needed form a metal.

If, control device on the other side of the master key blank is further by milling if the called party determines that the whether can be distinguished from, control device by flip key to the user key, on opposing sides of the receiver (28) indicates the to expose of observations (step 138). A master key user flip and housing (22) after the reclosable packaging the door of the consignee home delivery, control device a key subset of some or its opposing sides of confirmation in its entirety of. and which may progress towards process. For example, said 2 irradiation and irradiation rear view process may comprise an steps. Or alternatively, only the irradiating step upper surface only process confirming from that subroutine and then resumes supplying outlet of milling opposing sides of the key can be determines the pattern.

The present invention refers to disclosure a key identification system the key cutting machine may be used with the unexpected that. Control device for analyzing map edge of a key that additional step is carried out (key cut code) code cut a key to of blades key.. Key cut code master key blade cut position, depth and each defining a. Key cut code memory (82) can be saved to, LCD display (34) or displayed on, or key cutting machine can be transmitted to. Key cut code sections providing electrical connection and/or direct through on network can be transmitted to the key cutting machine 2000. Alternatively, the, are correct system of the present invention to identify the key blank, said blank is publicly known polishing trays are shipped (tracing) techniques by cutting so as to correspond to master may be is.
