A non-volatile memory system of a type having blocks of memory cells erased together and which are programmable from an erased state in units of a large number of pages per block. If the data of only a few pages of a block are to be updated, the updated pages are written into another block provided for this purpose. Updated pages from multiple blocks are programmed into this other block in an order that does not necessarily correspond with their original address offsets. The valid original and updated data are then combined at a later time, when doing so does not impact on the performance of the memory. If the data of a large number of pages of a block are to be updated, however, the updated pages are written into an unused erased block and the unchanged pages are also written to the same unused block. By handling the updating of a few pages differently, memory performance is improved when small updates are being made. The memory controller can dynamically create and operate these other blocks in response to usage by the host of the memory system.

A non-mechanical gimbal system is presented. The gimbal system includes a gimbal housing, including hemispherical and annular caps, rotatable sphere, and at least two curvilinear actuators. The hemispherical cap is attached to the annular cap in a removable fashion so as to surround the rotatable sphere. The curvilinear actuators are disposed between the rotatable sphere and gimbal housing. Curvilinear actuators rotate the rotatable sphere, via shear induced motion, with respect to the interior surface of the gimbal housing. The present invention has immediate applicability within security devices, games, toys, weapons (including guidance systems and aiming), and communication systems.

A messaging system (1) has a provisioning server (2), an application server (3), a notification server (4), a mail server (7), and a voice / video server (8) which act as clients toward an LDAP directory server (5). A proxy (“DAP”, 6) performs high speed write operations on a subset of attributes which it determines to be dynamic attributes. LDAP client requests that do not involve dynamic attributes are forwarded to the directory server (5) in a conventional manner. The proxy (6) also joins the results of requests that have both high-speed dynamic attributes as well as “static” attributes that are stored in a directory server (5). “Intelligent” services that involve maintaining dynamic attributes for large number of subscribers in a distributed environment can be deployed.

A wireless communication device including a radio frequency (RF) circuit, a ZIF transceiver and a baseband processor. The ZIF transceiver includes an RF mixer circuit that converts the RF signal to a baseband input signal, a summing junction that subtracts a DC offset from the baseband input signal to provide an adjusted baseband input signal, and a baseband amplifier that receives the adjusted baseband input signal and that asserts an amplified input signal based on a gain adjust signal. The baseband processor includes gain control logic, DC control logic and a gain interface. The gain control logic receives the amplified input signal, estimates input signal power and asserts the gain adjust signal in an attempt to keep the input signal power at a target power level. The DC control logic estimates an amount of DC in the amplified input signal and provides the DC offset in an attempt to reduce DC in the amplified input signal. The gain interface converts gain levels between the gain control logic and the DC control logic. The RF signal may include in-phase (I) and quadrature (Q) portions, where the RF mixer circuit splits I and Q baseband input signals from the RF signal. Operation is substantially identical for both I and Q channels. The DC control logic operates to remove or otherwise eliminate DC from the received signal that is provided to decoders in the baseband processor.

A calibrated DC compensation system for a wireless communication device configured in a zero intermediate frequency (ZIF) architecture. The device includes a ZIF transceiver and a baseband processor, which further includes a calibrator that periodically performs a calibration procedure. The baseband processor includes gain control logic, DC control logic, a gain converter and the calibrator. The gain converter converts gain between the gain control logic and the DC control logic. The calibrator programs the gain converter with values determined during the calibration procedure. The gain converter may be a lookup table that stores gain conversion values based on measured gain of a baseband gain amplifier of the ZIF transceiver. The gain control logic may further include a gain adjust limiter that limits change of a gain adjust signal during operation based on a maximum limit or on one or more gain change limits. A second lookup table stores a plurality of DC adjust values, which are added during operation to further reduce DC offset. The calibration procedure includes sampling an output signal for each gain step of the baseband amplifier at two predetermined range values and corresponding DC offsets using successive approximation. The data is used to calculate gain, DC offset and DC differential values, which are used to determine the conversion values programmed into the lookup tables or the gain adjust limiter.

One advantage of the P×M antenna described herein is that the complementary antenna elements are combined without the use of a lossy, resistive matching network, thereby increasing the efficiency with which the P×M radiation pattern is produced.

A method of applying a profiled abradable coating onto a substrate in which an abradable ceramic coating composition is applied to a metal substrate using one or more coating application techniques to produce a defined ceramic pattern without requiring a separate web or grid to be brazed onto the substrate. The invention is particularly designed to withstand the higher operating temperatures encountered with the stage 1 section of 7FA+e gas turbines to allow for increased coating life without significant deterioration in structural or functional integrity. Typically, the grid pattern coating begins approximately 0.431″ after the leading edge of the shroud, and ends approximately 1.60″ before the trailing edge of the shroud. In the case of diamond-shaped patterns, the grid pattern will be about 0.28″ long and 0.28″ wide, with an overall thickness of about 0.46.″ The coatings thus provide the required levels of abradability and leakage performance and may be applied as a chevron or diamond pattern with the shape oriented such that the diagonals run perpendicular and parallel to the sides of the shroud.

A battery charger includes line-level input rectification, a high-frequency oscillator-controlled chopper circuit, multiple transformers operating in parallel, and controlled output rectification. Use of line-level input rectification reorders the elements of the battery charger compared to previous designs. A chopper frequency several orders of magnitude higher than that of the AC power mains is used. The use of multiple, parallel-wired transformers for voltage and current transformation eases constraints on the physical geometry of a manufactured battery charger product by permitting individual transformers, each smaller than a comparable single transformer, to be employed. Controlled output rectifiers permit power levels to be regulated dynamically.

A method and system are provided for updating software configurations of line-replaceable unit (LRU) computers in a restricted architecture network such as an in-flight entertainment system (IFES). Operating in an efficient and parallel manner, each of the LRUs independently creates an individual configuration file that identifies current software components. Each of the LRUs transmits its respective configuration file to a configuration server either automatically upon startup or manually upon request. The configuration server updates a system configuration data file with the current configuration files received from the individual LRUs. In a downloading method, a download server sends a list of desired software components to the LRUs. Each of the LRUs independently and simultaneously transfer (download) the needed software from the download server. The LRU independently requests the download server to download the needed software components. To improve scalability and reliability, the file transfers utilize standard protocols, such as FTP.

A zero-voltage-switched, full-bridge, phase-shifted DC-DC converter for use in a DC power supply or battery charger includes a power transformer, four switching transistors connected to form a full bridge, and a decoupling capacitor and resonant inductor connected in series to the primary winding of the power transformer. At high loads, i.e., high output voltages, the resonant inductor charges the stray and internal capacitance of the switching transistors. Under light loads or in a no-load condition, with the current through the resonant inductor insufficient to allow the inductor to recharge these capacitances, the combination of a second inductor connected at one end to the central tap of the power transformer's primary winding and at its second opposed end to the middle point of a capacitive voltage divider, permits the second inductor to store enough energy to effectively recharge the stray and internal capacitance of the switching transistors for improved operating efficiency.
