Abstract: The control system has a structure in which sensor apparatuses each having a data communication function are connected to an electronic control apparatus through a common communication line, and the sensors of the sensor apparatuses are connected to the electronic control apparatus through separate individual signal lines to transmit sensor signals to the electronic control apparatus. The electronic control apparatus is configured to, prior to transmitting communication data to one of the sensor apparatuses through the communication line, set the signal line connected to the selected sensor apparatus in a state in which the voltage of the signal line is outside a variation range corresponding to a voltage range of the sensor signal, and set the signal lines connected to the other sensor apparatuses to each of which the communication data is not addressed in a state in which the voltage of the signal line is within the variation range.

Abstract: A network device forwards a Session Initiation Protocol (SIP) setup request from an originating user device toward a destination user device via multiple network elements and intercepts a message-too-large error message sent from one of the multiple network elements to the originating user device. The network device automatically splits the session setup request into smaller SIP messages, where a size of each of the smaller SIP messages is less than or equal to a particular size of message that the network element will accept. The network device then notifies another one of the multiple elements that the session setup request has been split into the smaller SIP messages and sends, via the multiple network elements, the smaller SIP messages toward the destination user device on behalf of the originating device.

Abstract: The present invention provides, as one aspect, a control system having sensor units and an electronic control unit. The electronic control unit includes a transmission controlling means which sets a signal line connected to the sensor unit, which is a destination of communication data, to a first state, sets the signal line connected to the sensor unit, which is not the destination, to a second state, and transmits the communication data to the destination via a communication line. The sensor unit includes a reception controlling means which determines a state of the signal line connecting a sensor to the electronic control unit. When determining that the signal line of the sensor unit is in the first state, the reception controlling means receives the communication data and performs a predetermined process. When determining that the signal line is in the second state, the reception controlling means discards the communication data.

Abstract: A maskless charged particle lithography system comprises an electron-optical column and a data path. The column includes a blanker array including blanker elements. The data path comprises a preprocessing system, transmission channels, and a pattern streaming system. The lithography system is configured for exposing a target field in two passes by allocating a first beamlet subset for exposing a first field subset during a first pass and a second beamlet subset for exposing a second field subset during a second pass. A first beam selector selects a first pattern data subset containing exposure data for the first beamlet subset and a second pattern data subset containing exposure data for the second beamlet subset. Second beam selectors connect transmission channels assigned for transmitting the first pattern data subset to a first blanker elements subset, and transmission channels assigned for transmitting the second pattern data subset to a second blanker elements subset.

Abstract: A method and apparatus for guiding an operator in the alignment of the wheels of an automotive vehicle which has been either modified from a original manufacturer configuration, or for which no previously established alignment settings are known. Initially, the operator identifies known information about the vehicle and selects a desired characteristic of the vehicle for which the vehicle alignment is to be optimized. A set of initial alignment settings are presented to the operator, based upon the selected characteristic for the vehicle, and the vehicle alignment is adjusted thereto. One or more subsequent measurements of the vehicle are acquired. Alignment adjustments to further improve the selected characteristic, identified in response to the vehicle measurements are presented to the operator. The process of alignment adjustment, measurement, and presented adjustments is repeated until an optimal alignment setting for the selected characteristic is reached.

Abstract: A vehicle antenna system incorporated into at least one side-view mirror of a vehicle includes a forward directed antenna and a rearward directed antenna to transmit and receive signals over corresponding forward and rearward-directed detection fields, respectively. The antennas act as directional transmitters and/or receivers, and a processing circuit discriminates between signals from different antennas without requiring any of the antennas to transmit identification signals to the processing circuit. Signal discrimination is conducted in part by sequentially selecting each antenna to obtain a corresponding antenna signal and, if required for a particular application, comparing the obtained signal with previously obtained antenna signals. The vehicle antenna system can be used, for example, in conjunction with tire pressure sensors to detect low tire pressure in a particular tire.

The unlock signal is verified by the transceiver as valid before actuating the security mechanism. The transceiver is further arranged to select a channel for reception of the unlock signal and to embed the identity of the selected channel in the first signal, such that the transponder key transmits the unlock signal using the selected channel.

Abstract: A transmission system having an uninterrupted switchover function for a plurality of lines is disclosed. The aims are to prevent unnecessary switchover and to provide high quality transmission system even using low quality lines with a minimal hardware configuration of memories and a control circuit. On the transmitting side, a pulse for phase synchronization is inserted at the top of each signal frame. Such frame signals are branched to transmit on a plurality of lines. On the receiving side, an alarm or error in signals from lines is detected on a frame basis. Then, a line switchover is carried out at the unit of a frame after frame phases are synchronized. To synchronize the frame phases, elastic memories for producing variable amount of delay are used in addition to fixed-amount delay circuits. This enables to insert a sufficient amount of delay to generate required timings for detecting errors, controlling and performing a switchover etc.
