  • Patent number: 10334961
    Abstract: A portable device for controlling an external electrical adjustable apparatus is provided. The portable device has a case, a signal transmitter connected to the electrical adjustable apparatus, a tilt sensor sensing a tilted angle and a controlling operation, a memory storing a threshold angle and a processor. The processor generates a controlling signal according to the controlling operation, and transmitting the controlling signal to an electrical adjustable apparatus for making the electrical adjustable apparatus raise/lower. The processor further determines that the electrical adjustable apparatus has collision when receiving a controlling signal used to control the electrical adjustable apparatus and the tilted angle is not less than the threshold angle, and sends a stopping signal to the electrical adjustable apparatus via the signal transmitter for making the electrical adjustable apparatus stop raising/lowering when determining that the electrical adjustable apparatus has collision.

  • Publication number: 20170207060
    Abstract: A test structure for electron beam inspection and a method for defect determination using electron beam inspection are provided. The test structure for electron beam inspection includes a semiconductor substrate, at least two conductive regions disposed on the semiconductor substrate, a connection structure disposed on the two conductive regions, and a cap dielectric layer disposed on the connection structure. The method for defect determination using the electron beam inspection includes the following steps. An electron beam inspection is preformed to a test structure with an instant detector and a lock-in amplifier. Signals received by the detector within a period of time are amplified by the lock-in amplifier. A defect in the test structure is determined by monitoring the signals received by the detector and amplified by the lock-in amplifier. The inspection accuracy is improved by the test structure and the method for defect determination in the present invention.
