    • An enclosure is arranged for housing electronics associated with a luminaire and includes a first member including a mounting interface arranged to couple the first member to the luminaire and a second member mechanically coupled to the first member. The mounting interface facilitates provisionally coupling the first member to the luminaire and securing the enclosure to the luminaire. A corresponding mounting apparatus for securing an enclosure to a luminaire includes a mounting member having an opening and configured to be secured to a surface of a luminaire and a neck portion extending from the enclosure and configured to pass through the opening. The neck portion includes a neck opening that is configured to allow wiring to be routed from the electronics to the luminaire. The neck portion and the mounting member may include respective complementary surfaces to provide a mounting interface for provisionally coupling the enclosure to the luminaire.
    • 壳体被布置用于容纳与灯具相关联的电子设备,并且包括第一构件,其包括布置成将第一构件耦合到照明器的安装界面和机械地联接到第一构件的第二构件。 安装界面便于将第一构件临时耦合到照明器并将外壳固定到照明器上。 用于将外壳固定到照明器上的相应的安装设备包括安装构件,该安装构件具有开口并且构造成固定到照明器的表面和从外壳延伸并配置成穿过开口的颈部。 颈部包括颈部开口,其构造成允许布线从电子装置路由到照明器。 颈部和安装构件可以包括相应的互补表面,以提供用于将外壳临时耦合到照明器的安装界面。

    • A radio replacement using RFID technology in an RF-enabled device is provided. The RF-enabled handheld, portable, or otherwise mobile device is equipped with an RFID tag having read and write capability. Data exchange occurs between the RFID tag and a network of RFID interrogators placed to provide adequate coverage of the area over which the device might move. As a result of replacing a full functioning transmitting/receiving radio with an RFID tag, the cost of the RF-enabled device could be significantly reduced, its battery life could be extended, and it could operate in a frequency band that does not require FCC approval. Additionally, this invention could provide tracking and access control using the RFID tag and interrogators.
    • 提供了一种在射频使能设备中使用RFID技术的无线电更换。 支持RF的手持式,便携式或其他移动设备配备有具有读和写功能的RFID标签。 数据交换发生在RFID标签和RFID询问器的网络之间,RFID询问器被设置为提供设备可以移动的区域的足够覆盖。 由于使用RFID标签替换全功能的发射/接收无线电,所以可以显着降低RF使能设备的成本,延长其电池寿命,并且可以在不需要FCC的频带中工作 批准 此外,本发明可以提供使用RFID标签和询问器的跟踪和访问控制。

    • A balance circuit for an amplifier circuit having 2.sup.M amplifiers serially biased across a supply potential node and a common potential node, where M is an integer greater than 0, and having respective 2.sup.M -1 interstage bias nodes and voltages between the amplifiers which are driven by respective input drive signals provided by 2.sup.M -1 2-way power splitters. A voltage reference circuit provides as to each power splitter first and second reference potentials respectively associated therewith. A plurality of control circuits are associated with respective power splitters and interstage nodes. Each control circuit is responsive to the associated first and second reference potentials and the interstage bias node for controlling the signal levels of the first and second drive signals provided by the associated 2-way splitter as a function of the associated interstage bias potential relative to the first and second reference potentials.
