Motor-Driven Throttle Valve Device with Inductive Throttle Sensor and Inductive Throttle Sensor for Detecting Rotation Angle of Throttle Shaft of Motor-Driven Throttle Valve Device

Номер: US20130112168A1
Автор: Kenji Usui, Morio Kuwano, Yasuhisa Uchiyama
Принадлежит: HITACHI AUTOMOTIVE SYSTEMS LTD

In a situation where a conventional inductive throttle sensor is used with a motor-driven throttle valve device to detect the rotation angle of a throttle shaft, plural sensor connection conductor sections for connecting a connector terminal to a circuit board terminal section are formed on the cover on one lateral surface side of a circuit board in the long-axis direction. This increases the dimension of the cover in the short-axis direction (the dimension in the direction of air flow in an intake path). Consequently, it is difficult to install the motor-driven throttle valve device and inductive throttle sensor in a narrow engine room. This problem is addressed by using a separate member to achieve electrical conduction between a stator circuit board and a conductor routed inside the cover installed over the stator circuit board in a concentrated manner on one side of the circuit board. The problem is also addressed by disposing plural electrical conduction spots in a decentralized manner and away from a protrusion provided to limit the amount of axial movement of a gear.

Systems and methods for tracking the location of a non-destructive inspection (NDI) scanner using scan data converted into images of a target object. Scan images are formed by aggregating successive scan strips acquired using one or two one-dimensional sensor arrays. An image processor constructs and then compares successive partially overlapping scan images that include common features corresponding to respective structural features of the target object. The image processor is further configured to compute a change in location of the NDI scanner relative to a previous location based on the respective positions of those common features in the partially overlapping scan images. This relative physical distance is then added to the previous (old) absolute location estimate to obtain the current (new) absolute location of the NDI scanner. 1. A method for tracking a location of a scanner , the method comprising:(a) translating a scanner having a one-dimensional sensor array across a surface of a target object in an X direction at a known speed from a first X position to second, third and fourth X positions in succession;(b) acquiring successive sets of sensor data at a known capture rate as the scanner translates in the X direction;(c) converting the successive sets of sensor data to respective scan strips of scan image data;(d) constructing a first scan image from a first sequence of scan strips converted from sensor data acquired during movement of the one-dimensional sensor array from the first X position to the third X position;(e) constructing a second scan image from a second sequence of scan strips converted from sensor data acquired during movement of the one-dimensional sensor array from the second X position to the fourth X position;(f) finding feature points in the first and second scan images;(g) determining which feature points found in step (f) are common feature points in the first and second scan images;(h) computing a pixel position difference between ...

Presented here are system and methods for collecting information from devices, such as sensors, that are not necessarily connected to the Internet. Multiple sensors are distributed in a geographic area. The sensors power up every 10 minutes to gather data about the environment and then power down to save battery. A collecting device, i.e., a device attached to a moving object, traverses the geographic area containing the sensors, and continuously sends wake-up signals into the environment. When a sensor is within 20 feet of the collecting device, and receives the wake-up signal, the sensor uploads the gathered data to the collecting device. Subsequently, when the collecting device establishes an Internet connection, the collecting device uploads the gathered data to a central database. 1.

A refrigerator equipped with a door that becomes transparent as necessary to make the interior thereof visible is disclosed. The refrigerator includes a cabinet having a storage compartment defined therein, a lighting device for illuminating the interior of the storage compartment, a door, which is hingedly coupled to the cabinet to open and close the storage compartment, and has an opening and a panel assembly including a front panel disposed on the front surface thereof, a sensor for detecting sound waves, which are generated by a knock input applied to the door and are transmitted through the front panel, and a controller for controlling the lighting device to allow light to be transmitted through the panel assembly, thus making the storage compartment visible from outside the door through the opening when a predetermined knock input is detected. 130-. (canceled)31. A method for controlling a refrigerator comprising:receiving a knock input on a front surface of a panel assembly of a door;detecting, at a sensor device, the knock input, wherein a portion of the sensor device is provided at a rear side of the front surface of the panel assembly;in response to the sensor device detecting the knock input, turning on a lighting device such that an inner space behind the panel assembly is viewable through the panel assembly when the door is closed.32. The method of claim 31 , further comprising turning off the lighting device after a predetermined period of time from when the sensor device detects the knock input.33. The method of claim 31 , wherein the panel assembly includes a front panel configured to allow passage of light emitted from the lighting device when the door is closed claim 31 ,wherein the front panel includes a first area through which the light from the lighting device passes and a second area disposed outside the first area to block transmission of light therethrough, andthe portion of the sensor device is provided behind the second area of the front ...

Data is utilized more efficiently and effectively. A position detection device includes a plurality of scales that each record absolute data embedded with a scale ID for identifying a scale, a detector that detects the absolute data from each of the plurality of scales, and an extractor that extracts, from the detected absolute data, the scale ID and position data representing the position of the scale. 1. A position detection device comprising:a plurality of scales that each record absolute data embedded with a scale ID for identifying a scale;a detector that detects the absolute data from each of said plurality of scales;an extractor that extracts, from the detected absolute data, the scale ID and position data representing a position of said scale.2. The device according to claim 1 , whereineach of said plurality of scales includes specific absolute data, andsaid extractor comprises a storage that stores a correspondence between the specific absolute data and the scale ID.3. The device according to claim 1 , wherein said extractor extracts the position data by offsetting an offset value corresponding to the scale ID from the absolute data.4. The device according to claim 1 , whereinsaid detector comprises at least two detectors, andsaid extractor extracts the scale ID by comparing the absolute data detected by said at least two detectors.5. The device according to claim 1 , whereineach of said plurality of scales includes a first data area for embedding the scale ID and a second data area for embedding the position data, andsaid extractor extracts the scale ID using the absolute data detected from the first data area, and extracts the position data using the absolute data detected from the second data area.6. The device according to claim 5 , whereina value of the absolute data includes a value indicating a difference between the first data area and the second data area, andthe device further comprises a determinator that determines, based on the value indicating ...
