Abstract: A multiple access wireless communications architecture provides selective, simultaneous communications with wireless devices located in different sections of a spatial area around a communications apparatus referred to as “sectors”. This includes communications between wireless devices in a single sector, between wireless devices in different sectors and between wireless devices and a wired network or wireless backhaul network. The wireless communications architecture generally includes two or more wireless antenna arrangements that are each configured to provide communications with wireless devices located in a particular sector. Each wireless antenna arrangement is further configured to determine whether signals are being communicated on a communications channel before transmitting on the communications channel. This may be implemented, for example, using a carrier sense or energy detection mechanism.

Abstract: A system for acquiring environmental information measurements. The 5 system (100) utilize a sensor, (205) a front-end circuit, (310) a loop filter (315), a switch controller (206), and a reduced-order loop control circuit to provide reliable data measurements while providing robust system behavior. The system further includes a sensor simulator (330) for simulating the operation of the sensor (205) and testing the operation of the front-end circuit (310) and the loop filter (315).

Abstract: The present invention provides in one embodiment channel allocation and polarization techniques for reducing cross sector communications interference in a multiple access wireless communications environment. In one embodiment, channel allocation and/or polarization techniques may be applied in multiple-access wireless communications architectures to provide selective, simultaneous communications with wireless devices using a plurality of transmitters. In some embodiments, a transmitter is coupled to an antenna configured to provide simultaneous communications with wireless devices located in different spatial areas or sectors. In some embodiments, communications between wireless devices within a single sector, between wireless devices in different sectors and between wireless devices and a wired network or wireless backhaul network may be provided.

Abstract: A new built-in self-test architecture for multiple memories in a chip is proposed in the present invention. In this architecture, all memories under test are tested in parallel using only one address generator. When the address generated from the address generator exceeds one memory's address space the memory is turned off by a BIST controller. Each word in each memory is tested by a scan-in/out method. That is, the D flip-flops in the input and output ports of each memory are connected in series and form two scan chains, respectively. Only one data input and one data output are required for the scan chains of each memory. The outputs of all scan chains are connected to a self checker for fault analysis in parallel. The address generator, data generator, self checker and the test controller are all built in a chip to satisfy the requirement of built-in self-testing.

Abstract: A computer implemented method that allows C++ classes based on any particular class library to be generated from a standard User Interface Language (UIL) file generated by a variety of GUI builders. A programmer can then use these classes in a familiar manner rather than being forced to use the program framework favored by any particular GUI builder. The GUI builder may then be used as a tool to facilitate the creation of classes that are inherently graphical while leaving the programmer free to deal with the inherently non-graphical bulk of the program.
