To form a driver circuit to be mounted to a liquid crystal display device or the like on a glass substrate, a quartz substrate, etc., and to provide a display device mounting driver circuits formed from different TFTs suited for their respective operational characteristics. A stick driver circuit on the scanning line side and a stick driver circuit on the data line side are different in structure, and have different TFTs in which the thickness of a gate insulating film, the channel length and other parameters are varied depending on required circuit characteristics. In the stick driver on the scanning line side, which is composed of a shift register circuit, a level shifter circuit, and a buffer circuit, the buffer circuit has a TFT with a thick gate insulating film because it is required to have a withstand voltage of 30 V. The stick driver circuit on the data line side, which is composed of a shift register circuit, a latch circuit, a level shifter circuit, and a D/A converter circuit, is driven at a high frequency, and hence its shift register circuit and latch circuit have thin gate insulating films and the channel length thereof is shorter than that of the TFT of the buffer circuit.

A web crawler stores fixed length representations of document addresses in a buffer and a disk file, and optionally in a cache. When the web crawler downloads a document from a host computer, it identifies URL's (document addresses) in the downloaded document. Each identified URL is converted into a fixed size numerical representation. The numerical representation may optionally be systematically compared to the contents of a cache containing web sites which are likely to be found during the web crawl, for example previously visited web sites. The numerical representation is then systematically compared to numerical representations in the buffer, which stores numerical representations of recently-identified URL's. If the representation is not found in the buffer, it is stored in the buffer. When the buffer is full, it is ordered and then merged with numerical representations stored, in order, in the disk file. In addition, the document corresponding to each representation not found in the disk file during the merge is scheduled for downloading. The disk file may be a sparse file, indexed to correspond to the numerical representations of the URL's, so that only a relatively small fraction of the disk file must be searched and re-written in order to merge each numerical representation in the buffer.

A method and system for reducing the frequency of operation for a transversal Finite Impulse Response (FIR) filter is disclosed. In the preferred embodiment, the transversal filter operates in such a way that it has an even and odd row of data, which are latched on rising and falling edges of the clock respectively. This allows the clock frequency to be reduced by a factor of 2, and thus allows the use of more power efficient latches. A reduction in the frequency of operation causes the high speed latches within the transversal filter to hold the data bits twice as long as is required, which changes the desired impulse response of the FIR filter. A circuit is required to select the appropriate data bits from the output of the appropriate half-speed latch, and subsequently scale it to apply the co-efficient gain. Each of the subsystems is analog, and operates in accordance with a synchronous clock system. In a more general embodiment of the invention, the data is provided to Q shift registers that operate at a clock rate which is reduced by a factor of Q.

When the temperature of an engine and a main battery is low at the time of activating a vehicle system, an ECU starts the engine in advance and outputs a running permission signal after completion of engine startup. At this stage, the ECU suspends a defect diagnosis operation on a subsidiary load and feedback-controls the DC/DC converter by setting the voltage control value to a level lower than the output voltage from the subsidiary battery and at least the lower limit of the operating voltage of the ECU. The ECU feedback-controls the DC/DC converter by setting the voltage control value to a level of at least the output voltage of the subsidiary battery in response to completion of engine start-up. Then, the suspension of the defect diagnosis operation on the subsidiary load is canceled and a running permission signal is output.

The outage probability in an under-addressed optical MIMO system may be reduced by configuring a spatial-mode coupler at a transmitter and/or a spatial-mode separator at a receiver to dynamically change its spatial-mode configuration on a time scale that is shorter than the channel coherence time. Provided that the MIMO system employs an FEC code that has a sufficient error-correcting capacity for correcting the amount of errors corresponding to an average state of the MIMO channel established between the transmitter and receiver, this relatively fast dynamic change tends to reduce the frequency of events during which the number of errors per FEC-encoded block of data exceeds the error-correcting capacity of the FEC code.
