Abstract:
A connector for electrically connecting a first printed circuit board (PCB) with a second PCB wherein, in one example, the connector includes a housing having a keyed feature adapted to mate with a correspondingly keyed feature provided to each of the first and second PCBs and at least one connecting terminal carried by the housing having at least partially exposed opposed ends each of which electrically engages a contact pad formed on an underside of the respective PCBs. The connecting terminal may be arranged to accept a conductor and to thereby electrically couple the conductor to the first and second PCBs.

Abstract:
Described herein are antenna designs and configurations that provide flexible solutions for creating compact antennas with multiple-band capabilities. For example, a hybrid PIFA-monopole antenna configuration and design is described. As another example, non-planar (e.g., orthogonal) and composite radiating structures incorporating various radiating elements (110) and ground plane configurations (115,120) are described. Connective structures are also described for providing physical rigidity and ground plane connectivity to composite radiation elements. In embodiments described herein of composite radiating structures, multiple antennas may be included through passive radiating elements potentially combined with active circuitry. Composite radiating structures with multiple antennas may be used in multiple-in and multiple-out (MIMO) antenna applications. For example, multiple different antennas within the composite radiating structures may be created using radiating elements on one or more of the vertical and/or horizontal portions of the composite radiating structure.

The card (1) includes an electrical connection portion (150) to be electrically connected with the socket of the interface bus, and a connection reinforcing portion (170) to reinforce a mechanical connection with the socket of the interface bus, wherein the connection reinforcing portion (170) is at least partially removable.
Abstract:
Apparatus and methods for supporting a fluorescent lamp. The apparatus may include a ballast and one or more lamp holders. The lamp holders may be in electrical communication with the ballast via a conductor. One or more lamp holders may be removably attachable to the ballast. When a lamp holder is attached to the ballast, it may be attached in a manner that places the lamp holder in electrical communication with the conductor. The apparatus may include a lamp holder module that may support one or more lamp holders. When a lamp holder is attached to the lamp holder module, it may be attached in a manner that places the lamp holder in electrical communication with a conductor that is configured to distribute power to lamp holders that are attached to the lamp holder module.
