| 20090232102 | Walsh Code Management in a Code Division Multiple Access Cellular Wireless Communication System - A cellular wireless communication system and method of operation manages Walsh codes in order to ensure that sufficient Walsh codes are available to prevent call blocking and to support additional hand-off operations. In an initial operating condition, the cellular wireless communication system services normal hand-off operations in which a maximum number of cells and sectors may participate in hand-off. With hand-off operations according to the present invention, each cell or sector participating in hand-off for a mobile terminal uses a unique Walsh code for covering its forward link signals. When the number of Walsh codes available for servicing new calls is reduced so that it meets or exceeds a Walsh code availability threshold, the number of cells and sectors that may participate in hand-off is reduced from the maximum number. In the number of participating cells/sectors results in release or non-use of some Walsh codes. In subsequent operations when sufficient Walsh codes are available for servicing hand-off operations, a greater number, up to the maximum number of cells and sectors may again participate in hand-off of the mobile terminal. | 09-17-2009 |

| 20120025087 | MODFET active pixel X-ray detector - Detection of ionizing radiation with modulation doped field effect transistors (MODFETs) is provided. There are two effects which can occur, separately or together. The first effect is a direct effect of ionizing radiation on the mobility of electrons in the 2-D electron gas (2DEG) of the MODFET. An ionizing radiation absorption event in or near the MODFET channel can perturb the 2DEG mobility to cause a measurable effect on the device conductance. The second effect is accumulation of charge generated by ionizing radiation on a buried gate of a MODFET. The conductance of the MODFET can be made sensitive to this accumulated charge, thereby providing detection of ionizing radiation. 1-D or 2-D arrays of MODFET detectors can be employed to provide greater detection area and/or spatial resolution of absorption events. Such detectors or detector pixels can be integrated with electronics, such as front-end amplification circuitry. | 02-02-2012 |
