The invention discloses a single-drive intermittent electric rotary clamping jaw which comprises a motor, a lead screw, an inner threaded sleeve, a planetary transmission mechanism, a clutch mechanism, a linkage mechanism and a plurality of flexible jaw fingers. The lead screw is fixed to the output end of the motor, the internal thread sleeve is in threaded connection with the lead screw, the internal thread sleeve, the linkage mechanism and the flexible claw fingers are sequentially connected, the multiple flexible claw fingers are installed at one end of the planetary transmission mechanism in an overturning mode, and the clutch mechanism is used for connecting the internal thread sleeve with the planetary transmission mechanism. By imitating the principle that a bottle cap is screwed manually, clamping and rotating are achieved only through one motor, space and economic cost are greatly saved, the problem that a mechanical arm cannot reach a workpiece in a small space is creatively ...

Method for realizing quick data storage under Linux

Номер: CN0102147806A

The invention provides a method for realizing quick data storage under Linux. The method comprises the following steps of: (1) establishing a data caching document; (2) searching a physical unit address corresponding to the data caching document; (3) writing data to be stored into a physical unit corresponding to the data caching document; and (4) transferring the data caching document by Linux. In an OMAP (Open Multimedia Application Platform Processor), a DSP (Digital Signal Processor) core directly stores the data to the physical unit corresponding to the data caching document and directly saves the collected data to be a document mode, so that the data are prevented from being duplicated between a drive program and an application program; and establishment, initialization and transferring of the data caching document are completed by the Linux, so that the document management advantage of the Linux is played. By combining the OMAP and the Linux, the data storage speed is increased.

The invention provides a method for realizing high frame rate unambiguous positioning in a long baseline asynchronous acoustic positioning system; a signal is in a combined pulse string form at a signal emitting end; a CW signal and a LFM signal are alternatively used by the combined pulse string so as to reduce interference among pulses without reducing the frame rate since the frequencies of the sequent pulses are different; a processing method of the received signal comprises the following steps: performing the detection, time delay and frequency estimation of a CW pulse and a LFM pulse respectively by using a parallel multi-channel self-adaptive wave trap set and a parallel copy correlator set at a signal receiving end. The frame rate can be improved to 0.1s order by using the combined pulse string signal form so that the positioning system can be greatly improved in comparison with the present mature technology at home and abroad in terms of the track measurement frame rate, the positioning ...
