Abstract: A baud rate sampling receiver, for reducing signal overshoot and improving equalization of a communications channel. The receiver filters an input signal, samples the filter output signal at the baud rate, continuously monitors the filter output signal for overshoot using a latching comparator circuit, and controls filter parameters based upon the sampling and monitoring using a filter control. The latching comparator circuit includes a positive latching threshold comparator circuit and a negative latching threshold comparator circuit. Each of these comparator circuits provides a threshold control bit to the filter control in response to a detection of signal overshoot. While the filter control also receives information about the filtered output signal from a sampling circuit, the threshold control bits indicate to the adaptive filter control immediately, rather than at the next sample point, when signal overshoot is present. The filter control responds by appropriately adjusting filter parameters such as high frequency boost.

Abstract: Methods and systems of communication reduce the internal interference associated with conducting radio communication in a wireless local loop communication system down to acceptable levels. Problems associated with internal interference are solved by providing carrier frequency rotation during time slots in a frame. A plurality of radio fixed parts are utilized for conducting radio communication with user terminals. During operation, each of a plurality of sequentially related carrier frequencies is assigned in sequential order to a respective one of the plurality of radio fixed parts. Each of the plurality of carrier frequencies is advanced during each successive time slot during operation of the wireless system. In addition, the control system controls operation of the radio fixed parts by allowing and disallowing transmission and reception in certain predetermined time slots.

Abstract: Optimal operating techniques are disclosed for using coreless printed-circuit-board (PCB) transformers under (1) minimum input power conditions and (2) maximum energy efficiency conditions. The coreless PCB transformers should be operated at or near the 'maximum impedance frequency' (MIF) in order to reduce input power requirement. For maximum energy efficiency, the transformers should be at or near the "maximum efficiency frequency" (MEF) which is below the MIF. The operating principle has been confirmed by measurement and simulation. The proposed operating techniques can be applied to coreless PCB transformers in many circuits that have to meet stringent height requirements, for example to isolate the gates of power MOSFET and IGBT devices from the input power supply. <IMAGE>

Abstract: Cette invention porte sur un procédé et un appareil visant à améliorer la précision des procédés de gravure au plasma tels que des procédés de gravure de tranchées et sillons. Dans ces procédés, une tranchée ou sillon est gravée dans une couche de matériau qui ne possède pas de couche supérieure à la profondeur désirée des orifices formés par gravure. Le procédé de gravure s'effectue plutôt sur une durée définie, calculée de façon à obtenir une profondeur de gravure désirée sur la base des vitesses de gravure mesurées ou évaluées. Par exemple, la durée de la gravure pour obtenir une profondeur cible peut être basée sur une analyse statistique ou sur des mesures effectuées en temps réel des profondeurs de gravure par interférométrie. Toutefois, l'utilisation des vitesses de gravure estimées ou interférométrie, pour contrôler la fin de la gravure et obtenir une profondeur désirée, peuvent générer des structures défectueuses dues aux orifices trop profonds ou trop creux formés par gravure. L'invention porte également sur une technique de régulation du procédé de gravure de manière à obtenir des profondeurs de plus en plus précises en intégrant une étape de mesure de l'épaisseur de la couche de masquage au procédé de gravure.

Abstract: A communication protocol and hardware is provided which allows a meshed network to reliably perform in a real-time environment. The protocol establishes that within specified regions of a mesh, a single node will transmit on that region at any given time. The transmitted message is propagated to all other nodes in the region by flooding the network. Immediately upon receiving each bit of data, a receiving node will immediately retransmit that bit, thereby increasing the speed of the flooding. Arbitration and lockout logic is provided which assures that nodes receiving data from multiple sources will be able to correctly handle and retransmit that data.

The radio transmitter (30) comprises at least two push-buttons (1, 2) for the control of the lifting and lowering movement of the winding device and a first microcontroller (6) provided with a first code memory (7) that, at each pressure on at least one of said control push-buttons (1, 2), sends a codified signal having a respective identification code of the push-button being pressed. The radio receiver (40, 50) comprises a second micro-controller (12) with a second code memory (14), that at each signal being received with one of the codes of said second memory (14), generates a control signal for a control unit (18) provided with a third memory (25) that, upon reception of the control signal, starts the motor in one sense of rotation or in the opposite sense according to the identity of the push-button of the radio transmitter (30) that is being pressed, and receives identification data of the angle of rotation from an encoder (21) that is coupled to the motor, in order to allow the motor to rotate until it reaches a prefixed limit stop. The two microcontrollers (6, 12) and the control unit (18) are programmed to allow the electronic setting of the position of the lifting and lowering limit stops of the roller shutter through a proper sequential depression of said push buttons (1, 2). It is also possible to enable one transmitter to control a plurality of radio receivers. <IMAGE>
