  • Patent number: 11169254
    Abstract: An operation mode control method implemented by a radar system, the operation mode control method includes steps of: (S1) receiving a single target tracking (STT) triggering data comprising a representation of triggering of a STT tracking mode and a selected tracking target to be tracked by the radar system; (S2) controlling a radar sensor to emit detection wave beam; (S3) controlling, the radar sensor to receive echo waves; (S4) analyzing, echo signal to generate STT target data; (S5) executing a STT program to obtain a tracking data of a selected tracking target; (S6) outputting the tracking data to a memory device for storage or to a human-machine interface (HMI) device for presenting to the user of the radar system.

  • Patent number: 7305722
    Abstract: A facial washer is disclosed to include a basin, which has a plurality of water outlets symmetrically arranged on the inside wall thereof at two opposite lateral sides, a plurality of adjustable jet nozzles, which are respectively mounted in the water outlets inside the basin for ejecting a respective stream of water, each having a fixed ball socket and a ball valve rotatably supported in the ball socket for guiding water out of the respective water outlet in the form of a stream of water, and a control device for controlling the supply of water to the adjustable jet nozzles.

  • Patent number: 5705737
    Abstract: A pressure leakage detector includes a primary gage and a secondary gage selectively connected to each other by means of a valve. The primary gage is connected to an air compressor via a pressure regulator for regulating the pressure supplied thereto and has an outlet port adapted to directly continuously supply the pressure to a large container to detect the leakage of container by means of visual inspection. The secondary gage has an outlet port adapted to connect to a closed system on which a leakage detection is to be carried out. By opening the valve between the two gages to have the closed system reaches a predetermined internal pressured set by the regulator and then closing the valve, a leakage of the closed system may be found by a drop of the pressure reading of the secondary gage. Thereafter, a visual inspection will indicate the exact location of leakage. Thus a precise and correct detection on either a small volume closed system or a large container may be preformed in an quite easy manner.
