International Classification:

G06F 1300

US Classification:

395860

Abstract:

An application specific integrated circuit (ASIC)/field programmable gate array (FPGA) which is a component of a wireless LAN controller including a local processor and a memory enables the controller to interface with both PCMCIA. TM. and AT. TM. host computer systems. The ASIC/FPGA enables communication between a radio frequency communication module, a local processor, and the host computer. The ASIC/FPGA also includes a throttle feature that decreases the access of the host computer in comparison to access of the local processor in order to enable the local processor to rapidly generate an acknowledge signal as required by various RF LAN specifications. During operation of the controller, data to be transmitted by the host computer onto the network is written by the host to an SRAM via the ASIC/FPGA, and the host commands the local processor via the ASIC/FPGA to forward the transmitted data to the RF communication module. Under the control of the ASIC/FPGA, the local processor then forwards the transmit data from the SRAM to the RF communication module. When data is received from the RF communication module, the local processor, under the control of the ASIC/FPGA, receives the data and stores the received data in the SRAM.

International Classification:

G02B 6/42
G01T 1/29
G01T 1/20

Abstract:

A radiation detector is provided including a photosensor, a scintillator, and a light guide arranged between the scintillator and the photosensor and configured to guide light from the scintillator to the photosensor, the light guide including a nano-composite that includes nanoparticles that determine a refractive index of the nano-composite. The nano-composite includes a polymer material and the nano-particles, wherein the nano-particles are uniformly distributed throughout the polymer material so that the refractive index of the nano-composite is uniform throughout the nano-composite. Alternatively, the nano-particles are distributed throughout the polymer material so that the refractive index of the nano-composite is equal to the refractive index of the photosensor at a first boundary of the nano-composite that contacts the photosensor, is equal to the refractive index of the scintillator at a second boundary of the nano-composite that contacts the scintillator, and varies uniformly throughout the nano-composite between the first and second boundaries.

US Classification:

250214RC

Abstract:

A process and system including a detector having a photosensor therein that outputs a signal and a plurality of after-pulse detector devices independently connected to the photosensor via respective pathways. The after-pulse detector devices each detecting an after-pulse in the signal, where the after-pulse represents an after-event in the photosensor triggered from a previous photon generating event. The system further includes a processing device that receives an indication of the detection of the after-pulse from each of the plurality of after-pulse detector devices and determines a relative delay between the respective pathways based on timing the received indications, and includes a memory that stores the relative delay in association with an identification of the corresponding after-pulse detector devices.

International Classification:

G01T 1/164

US Classification:

250362, 25036303

Abstract:

Systems, devices, processes, and algorithms for adapting and/or adjusting a reflectivity of a reflector in a radiation detector. The reflectivity can be changed by a reflectivity control signal that is generated based on an estimated count rate of events so as to adjust a probability of a photosensor detecting light resulting from the event via, for example, a scintillation event. By adjusting the probability, an energy resolution of the radiation detector can be optimized. The reflectivity of a reflector can be changed by changing a state of a thin film, a liquid crystal layer, or a suspended magnetic particle layer.
