An electrical connector system has two connectors, one of which is included in a module mateable with the other connector in a pluggable manner. The other connector includes an elongated guide rail and a connector block in which are retained two or more electrical contacts. The guide rail by use of snap projections and recesses (11) may extend through an opening in a computer enclosure. A latch member is attached to the end of the guide rail in a manner that releases the latch member from the guide rail if the latch member is bumped or jarred to minimize the likelihood of damaging it. A grounding strip embedded in the guide rail makes electrical contact with the bezel through which it extends to protect against EMI. The ground strip includes raised contact portions (41) that engage a conductive bottom cover (39) of the module (72) and lower contact portions (53) for surface mount to a system circuit board (26).

An RF front-end architecture is operated in either a transmitting or a receiving mode. The RF front-end architecture comprises an antenna, an impedance match network, a balun and a transceiver chip. The transceiver chip comprises first and second transmit/receive (TR) switches, a transmitter, and a receiver. Because two TR switches are integrated into the chip, the printed circuit board area, BOM cost and pin count of the transceiver chip can be greatly reduced.

A system for testing transceiver modules associated to different multi-source agreement standards, comprising a transceiver testing device and an interface connection unit. The transceiver testing device comprises a processor for performing at least one testing operation on an MSA transceiver module associated to a certain multi-source agreement standard. The interface connection unit is suitable for connecting the MSA transceiver module to the transceiver testing device. The transceiver module includes a certain type of electrical connector element. The interface connection unit comprises a first connector component and a second connector component. The first connector component is adapted for being removably connecting the interface connection unit to the transceiver testing device. The first connector component is different from the certain type of connector element of the MSA transceiver module. The second connector component is suitable for connecting the interface connection unit to the certain connector element of the MSA transceiver module.

A Wireless Clamp-on Current Probe and an embedded system which includes a digital RF transceiver allows for remote test and measurement equipment to receive data from a current probe without regard to cabling issues such as size, physical wear, weight, cost, electrical noise, losses and more. Such a current probe may be used in environments and situations not previously explored. The probe may be controlled and queried by wired serial communication means or by means of an integrated radio frequency (RF) transceiver. The RF transceiver may utilize a proprietary communication protocol or a standard wireless communication protocol such as ZigBee, Bluetooth or any of the IEEE communication standards.

A tunable PLC optical filter having sequentially connected thermally tunable Mach-Zehnder (MZ) interferometers is described. The MZ interferometers, having free spectral ranges matching ITU frequency grid spacing, are tuned so as to have a common passband centered on the frequency of the signal being selected, while having at least one of the stopbands centered on any other ITU frequency. Any other optical channel that may be present at any other ITU frequency is suppressed as a result. The PLC chip, including a zero-dispersion lattice-filter interleaver stage, a switchable fine-resolution stage and, or a retroreflector for double passing the filter, is packaged into a hot-pluggable XFP transceiver package. A compensation heater is used to keep constant the amount of heat applied to the PLC chip inside the XFP package, so as to lessen temperature variations upon tuning of the PLC optical filter.

In one embodiment, the living room computer includes a housing, the housing including a small form-factor pluggable (SFP) port, a SFP cage coupled to the SFP port, the SFP cage configured to receive a SFP transceiver, a flat-panel display screen coupled to the housing, and a main board coupled to the flat-panel display screen. The SFP cage is configured to communicate with both optical fiber and copper wire networks. The main board includes a processor, a memory, and an SFP interface coupled to the SFP cage and to the processor. The processor is configured to receive data from the SFP interface and process the data for display on the flat-panel display screen. In one embodiment, the main board includes a wireless module and the processor is configured to process data received from the SFP interface for transmission by the wireless module, and the memory includes software executable by the processor such that the living room computer operates as an IEEE 802.11 access point.

High-speed serial interface or transceiver circuitry on a programmable logic device integrated circuit (“PLD”) includes features that permit the PLD to satisfy a wide range of possible user needs or applications. This range includes both high-performance applications and applications in which reduced power consumption by the PLD is important. In the latter case, any one or more of various features can be used to help reduce power consumption.

A modular shelf for an integrated display structure that addresses the mutually important, yet unrelated issues of inventory control, shelf labeling and point of purchase advertising. The modular shelf has a non-metallic low density core, a molded frame secured along the outer perimeter of the core, a thermoplastic or resinous sheet secured to each of the top face and the bottom face of the core, and a plurality of antennae embedded within at least one of the top sheet and the bottom sheet. An RF or other electronic transceiver is electrically connected to the antennae secured within a cavity of the rear molded member, and a power and communications connects the RF transceiver with a front video display panel and with power and communications components in a support base of a shelf gondola.

In a wireless network, a method for operating a wireless device including at least a wireless local area network (WLAN) transceiver and a Bluetooth (BT) transceiver, the method comprising facilitating a voice-over-IP (VoIP) call with another device using the WLAN transceiver and the BT transceiver; initiating a WLAN scanning operation by transmitting a probe request, over a wireless channel, to one or more access points (APs); instructing the one or more APs to delay sending a probe response for a delay period; and selectively terminating the WLAN scanning operation based at least in part on a determination that the wireless channel has been idle for more than a wait period after expiration of the delay period.
