摘要： A system comprises an embedded processor A, a processor or equipment B and a FPGA/CPLD module, wherein a synchronous serial port of the embedded processor A is connected with the FPGA/CPLD module; in which a transmission clock and transmission frame synchronization signal are taken as output, while a receiving clock and receiving frame synchronization signal are taken as input; and a communication interface of the processor or equipment B is connected with the FPGA/CPLD module. This system ensures that the data transmitting party always take initiatives during communications with processor of equipment B. Via the FPGA/CPLD module, the system may interface with other systems through different communication protocols, such that the system need not modify its solutions to adapt to different protocols, but only upgrades the logic of the FPGA/CPLD to adapt to the new interfaces. As such, a high-speed, reliable and flexible communication mechanism is established.

摘要： The present invention discloses a non-invasive blood pressure measurement apparatus and a safety protection method. In addition to a main pressure measurement circuit and a main microprocessor circuit, the measurement apparatus also includes an independently disposed assist pressure measurement circuit and an independently disposed assist microprocessor circuit. In normal measurement, the assist microprocessor circuit periodically samples a cuff pressure via the assist pressure measurement circuit, and compares the measured cuff pressure with a specified overpressure protection value, and if the cuff pressure exceeds the specified overpressure protection value, the assist microprocessor circuit outputs a control signal to open a deflation valve until the pressure falls to below the safety pressure. Compared with the prior art, the method for overpressure protection of the present invention is more direct and has higher accuracy of decision, leading to higher reliability of the overpressure protection and higher safety of the measurement apparatus.

摘要： Aspects of the subject matter described herein relate database virtualization. In aspects, clusters of database servers may be located at various locations of the Internet. When a client seeks to access a logical database, the client may send a logical server and logical database name in a data structure. These names may be used to find a physical server(s) and database(s) that correspond to the logical database. Once the location is determined, a proxy component is used to intercept and/or forward communications between the client and the physical server(s) and database(s) corresponding to the logical database. Using this system, a client may access data from a logical database without knowing the physical address of the logical user database.

摘要： A method and an apparatus for suppressing power frequency common mode interference which are used in a bioelectrical signal measuring system comprising a common mode interference signal extracting circuit and a driving circuit connected to the extracting circuit are provided. The driving circuit changes a phase of a common mode interference signal and amplifies the common mode interference signal, so as to output two-way amplified signals, wherein one amplified signal is selectively outputted to a living body on examination. In particular, the apparatus further includes phase compensating and processing means for receiving both a bioelectrical signal from the living body on examination and the other amplified signal outputted from the driving circuit, determining a phase compensation amount of the other amplified signal outputted from the driving circuit according to a characteristic value of the power frequency interference in the bioelectrical signal so as to phase-compensate the other amplified signal outputted from the driving circuit, and selectively outputting the phase-compensated amplified signal to the living body on examination. The method for suppressing power frequency common mode interference comprises the following steps of: receiving a bioelectrical signal from a living body on examination by phase compensating and processing means; analyzing the characteristic of the bioelectrical signal and determining a phase compensation amount by the phase compensating and processing means; performing a corresponding time delay processing on an amplified signal outputted by the driving circuit; and providing the delay signal to the living body on examination. According to this invention, the capability of the circuit for suppressing power frequency common mode interference is getting improved, and the stability of the analog circuit system and the phase-frequency characteristic of the circuit are maintained. This contributes to the improvement of the quality of the sampled bioelectrical signals.
