    • A portable cellular telephone comprising a main body for housing at least a microcontroller, a display screen, an audio receiver and a microphone. An extendible section that houses a number of function keys such as the standard telephone keys, slides out of the main body to expose the display screen in its entirety. The extendible section also includes LED's to back light the keys when desirable. The electrical connections between the extendible section and the main body are achieved through wiper contacts in the main body that slide over conductive strips on the under surface of the extendible section. The keys in the extendible section are each connected to resistors of different values, these resistor/key combinations are all connected in parallel to two conductive strips. A resistor bridge is formed by connecting a resistor in the main body to the resistor key combinations. The voltage change at the junction between the resistor and the combinations is detected to sense the closure of a key, and the voltage value is used to identify the key that is closed. The device also detects when the extendible section is in the open or closed positions. The extendible section is mounted such that it will detach from the main body when a force is applied to it such as by dropping the telephone; the section may be simply replaced by snapping it back into place without damage to the telephone.
    • 一种便携式蜂窝电话,包括用于容纳至少微控制器的主体,显示屏,音频接收器和麦克风。 容纳诸如标准电话键的多个功能键的可延伸部分从主体滑出以使显示屏全部曝光。 可延伸部分还包括LED,以便在需要时背光。 可延伸部分和主体之间的电气连接通过主体中的擦拭器触点实现,其在可延伸部分的下表面上的导电条上滑动。 可扩展部分中的键各自连接到不同值的电阻器,这些电阻/键组合全部并联连接到两个导电条。 通过将主体中的电阻连接到电阻器键组合来形成电阻桥。 检测电阻和组合之间的结点处的电压变化,以检测键的闭合,并且使用电压值来识别关闭的键。 该装置还检测可延伸部分何时处于打开或关闭位置。 可延伸部分被安装成使得当施加力时例如通过掉落电话机从主体脱离; 该部分可以简单地通过将其卡扣回到原位而不损坏电话来代替。

    • An improved transactional drawer and method for reciprocating the drawer relative to its housing and opening the customer door in a sequential multi-stage manner. The drawer assembly preferably comprises a housing, a drawer and a customer door, wherein the drawer is free to reciprocate relative to the housing by interaction of a rail and corresponding slot guide track arrangement. A low powered reversible power source selectively reciprocates the drawer relative to the housing, a cam actuator, and the interaction of a cam actuator and follower arrangement mechanically moves the customer door between pre-determined opened and closed positions in a sequential multi-stage manner in response to the reciprocation of the drawer. A seal member is located between the customer door and at least a portion of the front edge of the housing when the door is in its closed position, and one stage of the sequential multi-stage mechanical movement of the door is provided in a direction substantially only normal to the seal member to minimize stresses on the seal member during opening and closing procedures.

    • A conveyor system for delivering items between a processing station and a remote delivery station includes a pair of flexible drive members and a pair of spaced apart drive guides each positioned to define a path of travel for one of the drive members between the stations. A carrier member having an item receiving portion and upper and lower ends is attached to both of the flexible drive members adjacent one of its upper or lower ends for reciprocation between the stations along the guides. A third flexible stabilization drive member and a corresponding stabilization guide is positioned to define a third path for the stabilization drive member. The carrier member is attached to the stabilization drive member adjacent to the other of its upper or lower ends. The active stabilization guide member provides for more uniform and stable translation of the carrier member between the stations. The invention also provides an adjustable mount connecting the stabilization drive member to the carrier member, and which allows for automatic adjustment of the predetermined spacing between the carrier journal for one or more of the drive members and the stabilization journal for the stabilization drive member, further enhancing stabilization of the system and maintenance of the carrier member in a desired orientation between the stations.
