    • Methods, systems, and apparatuses for a reader transceiver circuit are described. The reader transceiver circuit incorporates a frequency generator, such as a surface acoustic wave (SAW) oscillator. A reader incorporating the reader transceiver circuit is configured to read a tag at very close range, including while being in contact with the tag. The transceiver can be coupled to various host devices in a variety of ways, including being located in a RFID reader (e.g., mobile or fixed position), a computing device, a barcode reader, etc. The transceiver can be located in an RFID module that is attachable to a host device, can be configured in the host device, or can be configured to communicate with the host device over a distance. The RFID module may include one or more antennas, such as a first antenna configured to receive a magnetic field component of an electromagnetic wave and a second antenna configured to receive an electric field component of an electromagnetic wave. The RFID module may include a detector that is configured to determine if the RFID module is positioned in proximity to an object, such as a RFID tag. The detector may operate as a trigger for the RFID module, to enable or trigger a function of the RFID module.
    • 描述了用于读取器收发器电路的方法,系统和装置。 读取器收发器电路包括频率发生器,例如表面声波(SAW)振荡器。 包括读取器收发器电路的读取器被配置为在非常接近的范围内读取标签,包括在与标签接触的同时。 收发器可以以各种方式耦合到各种主机设备,包括位于RFID读取器(例如,移动或固定位置),计算设备,条形码读取器等中。收发器可以位于RFID模块中 可附接到主机设备,可以在主机设备中配置,或者可以被配置为在一定距离上与主机设备进行通信。 RFID模块可以包括一个或多个天线,诸如被配置为接收电磁波的磁场分量的第一天线和被配置为接收电磁波的电场分量的第二天线。 RFID模块可以包括被配置为确定RFID模块是否位于诸如RFID标签之类的物体附近的检测器。 检测器可以用作RFID​​模块的触发器,以实现或触发RFID模块的功能。

    • Described is an improved trigger assembly for use in an electronic device. The trigger assembly includes a pressure sensitive member and a trigger button. The pressure sensitive member includes two or more conductive lines. The pressure sensitive member is secured to a portion of the mobile terminal. The trigger button is secured to the mobile terminal in a manner such that a force applied to the trigger button causes a resultant force to be applied on the pressure sensitive member. The force applied on the pressure sensitive member causes a change in an electrical property between at least two of the conductive lines. A module measures the electrical property between the conductive lines. A function of the device is initiated depending on a comparison of the measured electrical property to a threshold value.
    • 描述了一种用于电子设备的改进的触发器组件。 触发器组件包括压敏元件和触发按钮。 压敏元件包括两条或更多条导线。 压敏构件被固定到移动终端的一部分。 触发按钮以使得施加到触发按钮的力导致对压敏部件施加合力的方式固定到移动终端。 施加在压敏构件上的力导致至少两条导线之间的电性能的变化。 模块测量导线之间的电气特性。 取决于所测量的电气特性与阈值的比较来启动该装置的功能。
