    Abstract: PROBLEM TO BE SOLVED: To provide the detecting method for key depression which is simple and does not require a periodic toggle of processor output. SOLUTION: One of L keys 114 toggles characteristic combinations of at least N out of M inputs 600 when pressed, and the respective characteristic combinations are taken out of all possible combinations. At least M inputs 600 are read by a processor 506 and compared with specific key patterns 806. When there is a match between the M inputs 600 and one of the specific key patterns 806, the key depression is detected and a specific function can be processed in response. The processor 506 can ignore simultaneous key depression where combinations of inputs more than N are toggled.

    Abstract: An electronic device (100) includes at least L keys (114) and a processor (506) having at least M inputs (600). Upon actuation, each one of the at least L keys (114) toggles a unique combination of N inputs of the at least M inputs (600), where each unique combination is taken from all possible combinations thereof. The at least M inputs (600) are read by the processor (506) and compared to a plurality of predetermined key patterns (806). Upon a match between the at least M inputs (600) and one of the plurality of predetermined key patterns (806), a key actuation is detected and a predetermined function may be processed in response thereto. The processor (506) may ignore simultaneous key actuations where combinations of inputs greater than N are toggled.

    Abstract: A keyboard (102) includes fist (112) and second (110) hinges that allow the keyboard (102) to be properly placed and fitted against an electronic device such as a cellular telephone (106). The first hinge (112) allows the keyboard 102 to be swung up and away from the cellular telephone's housing and also allows the keyboard (102) to be properly fit against the cellular telephone's housing when in use. This proper fit provides for improved stress relief away from connector (108) when the keys (104) are activated. The second hinge (110) makes it easy for the keyboard (102) to be attached to cellular telephone (106) using connector (108). The dovetail design (308) of the underneath of the keyboard provides amble clearance (302) for the cellular telephone's keys (304).

    Abstract translation: 键盘（102）包括第一（112）和第二（110）铰链，其允许键盘（102）适当地放置并安装在诸如蜂窝电话（106）的电子设备上。 第一铰链（112）允许键盘102向上摆动并远离蜂窝电话的外壳，并且还允许键盘102在使用时与蜂窝电话的外壳适当地配合。 这种适当的配合提供了当键（104）被启动时，远离连接器（108）的改进的应力释放。 第二铰链（110）使得使用连接器（108）将键盘（102）容易地附接到蜂窝电话（106）。 键盘下面的燕尾设计（308）提供蜂窝电话的键（306）的离散间隙（302）。

    Abstract: Un dispositivo electronico (100) incluye cuando menos L teclas (114) y un procesador (506) que tiene cuando menos M entradas (600). Al accionarse, cada una de las cuando menos L teclas (114) palanquea una combinacion unica de N entradas de las cuando menos M entradas (600), en donde cada combinacion unica se toma a partir de todas las combinaciones posibles de las mismas. Las cuando menos M entradas (600) son leídas por el procesador (506), y se compara con una pluralidad de patrones de teclas previamente determinados (806). Cuando hay una concordancia entre las cuando menos M entradas (600) y uno de la pluralidad de patrones de teclas previamente determinados (806), se detecta un accionamiento de tecla, y se puede procesar una funcion previamente determinada en simultáneos en donde se palanquean combinaciones de entradas mayores que N.

    Abstract: A shield is for an electrical circuit (104) that is disposed on a substrate (102). The shield includes a base (106) to be mounted to the substrate (102) and an integral cover (108). The integral cover is joined to the base by filaments (220 Fig.2, not shown). The filaments are broken away when the integral cover is pulled off of the base. A replacement cover (700 Fig.8, not shown) includes fingers (702) to engage the base after the integral cover is removed.
