MULTIPLE CHARACTER GENERATOR

... 1285288 Cathode-ray tube character display BUNKER RAMO CORP 19 Aug 1970 [8 Oct 1969] 39998/70 Heading H4T An arrangement for decoding special characters (e.g. a character representing a frequently-used word or phrase) and converting each into a string of alphanumeric characters comprises a detector 28 which when one of these characters is recognized sets flip-flop 14 to disable at 18 the normal path for the character signals from keyboard 12 to memory 26 and to enable a counter 36. The first four bits of the composite character passes to matrix 32 together with the count (zero) registered in 36, and this matrix (which may be a diode matrix or other read-only store) generates the first alphanumeric character which passes via gates 40 and 22 to memory. Counter 36 is advanced at each character clock time to step the input to 32, thus producing a sequence of output characters until an 'end-of-sequence' code recognized at 52 resets 14 and 36.

First detection information related to electrical connection between each row signal line and each column signal line is received from a key matrix circuit (S 101 ). Based on the first detection information, it is determined whether a possibility exists that a user has pressed at least three key switches simultaneously and electrical connection between signal lines for a key switch that has not been pressed has been erroneously detected (S 108 ). Information in accordance with key switches pressed by the user is output based on the first detection information when the determination is negative (S 109 ), whereas output of information based on the first detection information is blocked when the determination is positive.

Method for forming switching circuit of keyboard without generating phantom phenomenon

A method for forming a keyboard switching circuit without generating phantom phenomenon is disclosed. The method includes the steps of (1) forming a matrix of nodes with input/output terminals of the keyboard circuit; (2) selecting nodes from the matrix to define a reference diagonal line which divides the matrix into upper and lower portions; (3) selectively selecting nodes of the matrix in the upper and/or lower portions to define diagonal lines parallel to the reference line, the diagonal lines being located at different distance from the reference lines and the nodes of the diagonal lines forming no rectangle with each other; and (4) setting switches in the selected nodes. Since no rectangle can be formed among the switches, no reverse current may be caused by simultaneous actuation of three switches of a rectangle and thus effectively eliminating phantom phenomenon.

键盘扫描器装置及方法

一种数字键盘输入装置包括一个控制器，该控制器用于驱动多条I/O信号线，使它们有选择性地处于输入态，输出态和高阻态。每条工作于输出态的线提供一输出逻辑信号，此信号经过合上的相应开关，被另一条工作于输入态的I/O线所检测。其它线都工作于高阻态。本发明的方法能使手动开关数目多于I/O线数目。

一种改进型矩阵按键扫描电路及方法

本发明公开了一种改进型矩阵按键扫描电路及方法，以对8个按键进行扫描为例，它由开关S1‑S8、电阻R1‑R8以及单片机MCU组成，所述单片机MCU的IO口之一A口接电阻R1的一端，电阻R1另一端分别与开关S1、开关S2、开关S5、开关S6的第2脚以及电阻R6的一端相连接，开关S1的第1脚与二极管D1阳极相连接，开关S2的第1脚与二极管D2阴极相连接，开关S5的第1脚与二极管D5阳极相连接，开关S6的第1脚与二极管D6阴极相连接，本发明比常规的矩阵式扫描检测电路可节省更多的IO口资源。比如，以对8个按键进行扫描为例，按传统矩阵扫描电路，至少需要6个IO口，但在本发明方案中，却只需要4个IO口即可，同比具有明显的资源优势和性价比优势。

键盘装置

本发明提出一种键盘装置。键盘装置包括按键模块以及检测电路。按键模块包括多个按键、多条扫描线以及多条回报线。此些扫描线与此些回报线彼此交会并分别耦接到此些按键。检测电路耦接此些回报线，用以检测流经此些回报线的每一者的电流，并根据电流的大小以指示出此些按键中的每一者的开关是处于导通状态或不导通状态。本发明所提出的键盘装置可避免发生鬼键现象。

Continuous automatic key control

Architecture for enabling continuous operation of a control command issued by a control input (e.g., a control key on a computer keyboard or game controller). For example, for a user of a software application (e.g., a gaming application), an activation modifier is used for enabling continuous operation of the control command. The activation modifier can be a lock key or other type of input used in combination with the control key. During continuous operation of the control command, one or more alternate control inputs (e.g., from alternate control keys) are enabled to concurrently issue alternate control commands to the software application.
