摘要:
A general pressure sensor for an automobile comprising a sensor shell, a silicon piezoresistive sensitive core, a sensor core seat, a signal conditioning circuit, and an automobile electric device interface is disclosed. The silicon piezoresistive sensitive core, the sensor core seat and the signal conditioning circuit are disposed in the inner cavity of the sensor housing. The sensor housing is installed to the automobile electric device interface, and the silicon piezoresistive sensitive core comprises a silicon piezoresistive sensitive element and a glass ring sheet. The silicon piezoresistive sensitive element is welded and fixed to a surface of the glass ring sheet. An insulation oxidation layer is formed on one surface of the glass ring sheet and the silicon piezoresistive sensitive element. The other surface of the glass ring sheet is hermetically fixed to the ring-shape recession surface provided on the sensor core seat. The sensor core seat is hermetically and rotationally fixed to a pressure inlet on the sensor housing, after the inner lead wire on the silicon piezoresistive sensitive core is led to an interposing board provided on one end of the central hole through the other end of the central hole on the ring-shape recession surface of the sensor core seat, and then is led out by the automobile electric device interface via the signal conditioning circuit.

A lever control mechanism of a drain valve of a toilet tank has a lever assembly assembled in the wall of the toilet tank and a lever linked to the revolving shaft of the lever assembly. The lever assembly is connected to a deviator, which is disposed with a drive arm; the drive arm is connected to the revolving shaft. The deviator is disposed with a joint portion and at least a leading hole to limit the lever revolving vertically. One end of the lever is run through the leading hole to rotationally connect to the joint portion; the drive arm is revolved by the driving of the revolving shaft to drive the lever revolved in the fan shaped vertical surface limited formed by the joint portion and the leading hole.
摘要:
A memory macro includes a tracking circuit and a plurality of memory cells. The tracking circuit has tracking transistors configured to receive a tracking voltage value. Each memory cell of the plurality of memory cells has memory transistors configured to receive a cell voltage value different from the tracking voltage value. The tracking circuit is configured to generate a tracking signal based on which a reading signal of a memory cell of the plurality of memory cells is generated.

A two level cross-correlation based system for watermarking continuous digital media at the system application level. It is a post-compression process for watermarking where no a priori knowledge of the underlying compression algorithm is required. Per each compressed media frame, a current unique digital signature is generated based on the data from the current compressed frame plus the digital signature that has been previously generated. The signature thus generated is then used in conjunction with the next compressed frame to generate the next unique digital signature. All digital signatures are correlated according to the above process until a “reset” signal is issued. A new chain of correlated digital signatures is produced by the system with a predetermined initial signature.

摘要:
A Static Random Access Memory (SRAM) includes at least two memory cells sharing a read bit line (RBL) and a write bit line (WBL). Each memory cell is coupled to a respective read word line (RWL) and a respective write word line (WWL). A write tracking control circuit is coupled to the memory cells for determining a write time of the memory cells. The write tracking control circuit is capable of receiving an input voltage and providing an output voltage. The respective RWL and the respective WWL of each memory cell are asserted during a write tracking operation.
