Abstract: A LED-based replacement light for a fluorescent socket is constructed such that an entirety of a radially outer portion of a tubular housing at least partially defined by a high-dielectric light transmitting portion is formed of a high-dielectric material. Forming a radially outer portion of the tubular housing of a high-dielectric material prevents a person handling the light fiom being shocked as a result of capacitive coupling occurring when the LED-based replacement light is installed one end at a time. A circuit board is in thermally conductive relation with the tubular housing, allowing for conduction of heat generated by the LEDs from a side of circuit board opposite the LEDs to the tubular housing for dissipation to the ambient environment.

Title: Mapping of discovery channel to a control channel in a device to device network
Inventor: GAO CHUN YAN
IPC: H04W4/50
Filed: 2011-12-19
Abstract: A method, apparatus and software related product provide device discovery and device to device (D2D) operation in, for example Long Term Evolution (LTE) wireless systems, by using control signalling provided by a wireless network (e.g. by a base station or eNB). The discovery channel/channels which convey(s) discovery signal/signals are configured by a network (e.g. by the eNB) and are mapped to control channel(s) (e.g. one-to-one). After sending/receiving the discovery signal/signals, the D2D devices monitor control channel/channels to get current information for establishing the D2D communication among these D2D devices. The current information may include a resource allocation for the D2D communication and a device list of candidates for establishing the D2D communication. As transmission and detection of discovery signals is typically undertaken in the same frequency band, the above wireless network assisted method is an attempt to schedule resource allocation in the discovery process for D2D systems.

Title: Mixing audio data samples using multiply-accumulate blocks and ping-pong buffers
Inventor: MACKAY GRAEME GORDON
IPC: G06F3/16
Filed: 2012-05-25
Abstract: An integrated circuit with analogue/digital audio inputs/outputs is used for configurable digital signal routing from input data sources to output data destinations. Signal routing can include mixing using a mixing fabric comprising one or more multiply-accumulate (MAC) blocks, which operate on a time division multiplexed (TDM) basis and take audio sample data from data sources, perform any required scaling (multiplication) to produce partial results which are temporarily stored and summed with subsequent/previous partial results to generate output audio sample data for a data destination. The mixer may also comprise source and destination buffers, such as ping-pong buffers, which enable input audio data samples and output audio data samples to be buffered for an entire period of a data sample clock so that the multiply-accumulate block and destination can retrieve the data at any point in the period. Multiple signal paths can be defined by configuration data supplied to the circuit and each has a respective sample clock rate. Paths with different sample clock rates can be routed through the multiply-accumulate block independently of each other.

Title: A pulsed radar transmitter amplifier with rapid turn-off
Inventor: KOBAYASHI TOMONAO
IPC: G01S7/282
Filed: 2012-10-04
Abstract: A pulsed radar transmitter amplifier with rapid turn-off The close-in sensitivity of a pulsed radar system is improved by driving the drainÂ  supply of the transmitting GaAs transistor 31 with a pull-up NFET 212 that respondsÂ  rapidly to a rise in the control signal Pconi. The gate charge of NFET 212 is discharged quickly through NFET 211 when Pconi goes to a high level. The NFETÂ  pull-up device 212 is turned on by charge delivered from bootstrap capacitor 215Â  when Pconi goes low. The resistor 217C may be bypassed by a transistor (251,Â  figure 6) to shorten the turn-on time. The gate supply for the GaAs transistor 31 isÂ also pulsed but does not need to provide a rapid response.
