Abstract: At the driving initiation, whether the output channels are enabled or disabled is determined by judging whether the voltages of the output channels are changed by a charging or discharging operation. The current output sources corresponding to the disabled output channels are turned off for power-saving. In the voltage conversion, the status of the disabled output channels is ignored, for accurately control of the voltage conversion.

Abstract: A switching power supply system, in which a DC voltage obtained by full-wave rectification of an AC voltage is turned on and off by a switching device, converted to a desired DC voltage and outputted, includes a slope compensating circuit and an overcurrent protecting circuit, and a full-wave rectified voltage inputted to a terminal Tm is subtracted from a reference voltage Vref inputted to a terminal Tr to produce a reference voltage waveform signal (OCP correction value) Vocp to eliminate the influence of slope compensation. The reference signal of the overcurrent protection circuit is varied by a signal having a reverse phased waveform relative to the phase of the full-wave rectified waveform. This enables highly accurate overcurrent protection with a net overcurrent protection level unaffected by the slope compensation varied by the input voltage when the system is operated in a current mode.

Abstract: The invention relates to a scraper blade assembly structure. The scraper includes a stem for hand grip and a scraping section in the front. The scraping section includes a jaw plate, a blade and a fastening button. The jaw plate extends backward to form an arm. The jaw plate is attached to the inside of the jaw plate groove of the scraping section by a fastener that also serves as a lever pivot for swinging back and forth. When a fastening button goes into the inside of the jaw plate of the scraping section, it pushes the inner side of the arm of the jaw plate, and so as to generate a great holding power for the front of the jaw plate. Further, the fastening button can be a handle protruding from one side of the scraping section.

Abstract: A memory structure that improves a sensing accuracy of memory cells by dividing the main array into a number of memory units and sensing memory cells of each memory units with an appropriate set of reference currents. Each of the memory units corresponds to a reference group bit value, which indicates the appropriate set of reference currents. The appropriate set of reference currents is chosen from a number of sets of selective reference currents according to the threshold voltage distribution of each of the memory units. Thus, each of the memory units of the memory structure is sensed correctly with its own appropriate set of reference currents, and the improvement of sensing accuracy is therefore achieved.

Abstract: N channels of encoded data are added into added data, which is compared with a first threshold of 2M?1?A and a second threshold of 2M?1?1, where M is the number of the bit positions of the binary representation of N and A is defined by 2M?(N+1). When the added data is less than the first threshold, it is selected. When the added data falls between the first and second thresholds, inclusive, either the added data or shifted data, obtained by adding A to the added data, is selected. When the added data exceeds the second threshold, the shifted data is selected. Based on output data representing the values of the respective bit positions of the binary representation of the selected data, the k-th output data, where k is a natural number less than M, is amplified into k-th amplified data having an amplitude level of 2k?1, and the M-th output data is amplified into M-th amplified data having an amplitude level of 2M?1?A. The first to M-th amplified data are multiplexed into a CDM signal.

Abstract: A method of for accessing a first-in-first-out (FIFO) buffer is provided. The method comprises the following two steps. Firstly, issue a request to access a memory when the amount of the data buffered in the FIFO buffer is more than a threshold. Second, pop the data buffered in the FIFO buffer out to access the memory when the request is granted. If the FIFO buffer is a single-port FIFO buffer, the threshold is set based on the burst length of one burst of data. If the FIFO buffer is a dual-port FIFO buffer, the threshold is set based on the speed at which the data is pushed into the FIFO buffer and the speed at which the data is popped out of the FIFO buffer.

The examples of the redirect system include modified firewalls, IP sharing devices and gateways with examining mechanism. A user request is transmitted to the inner data system via the redirect system if the user request satisfies a certain safety condition. Otherwise, the user request is transmitted to a reaction system which provides virtual data similar to real data so that unauthorized users have the illusion of successfully hacking the inner data system. Meanwhile, the illegal activities are recorded and certain programs like Trojan programs can be used for executing reactions.
