    摘要： A computer configured to operate in diagnostic mode during which the operating system is suspended. During the diagnostic mode, tests can be performed on the computer system, including hardware, and the tests do not disrupt the operating system and are not disrupted by the operating system. When diagnostic mode is triggered, execution of the operating system is suspended. When the diagnostic tests are completed, the operating system may resume operation and test data may be made available within the operating system environment. Upon resuming, the state of the computer prior to entering diagnostic mode may be restored, preventing any changes made during diagnostic mode from interfering with operation of the operating system or application components.

    摘要： A film-thickness measurement apparatus of the present invention includes a lifter, a support mount, a light-emitting device, and a light-receiving device. With the center of a wafer staying in alignment with that of the support mount, the lifter places the wafer onto the surface of the support mount to determine the center of the wafer. While the wafer is being rotated about the center of the wafer, the light-emitting device irradiates the circumferential portion of the wafer with a laser beam, thereby allowing the position of a notch to be detected depending on whether or not the laser beam passes through the notch. This makes it possible to detect the positions of the notch and the center of the wafer to determine the center axis line of the surface of the wafer, thereby allowing the coordinates of a given position on the surface of the wafer to be defined in accordance with the center axis line and the center of the wafer. The thickness of the thin film on the surface of the wafer at the predetermined positions can then be determined.

    摘要： Methods, systems, and devices for wireless communications are described. In some systems, wireless devices may encode and decode transmissions using polar codes. A transmitting device may encode a payload based on a selected payload size. For example, the transmitting device may construct a bit vector including payload bits, parity bits, frozen bits, or some combination of these, and may modify the bits or the order of the bits based on the selected payload size. The device may generate a polar-encoded codeword based on this bit vector, and may transmit the polar-encoded codeword to a receiving device. The receiving device may blind decode the polar-encoded codeword, and may determine the correct payload size based on the decoded bit vector. For example, the device may perform decoding or may check decoded bits based on a payload size hypothesis, where the decoding may fail for any incorrect payload size hypothesis.

    摘要： This invention publishes a fault diagnosis and location system for transformer core looseness, consists of vibration sensors, data collection and computer. It is of power transformer fault intelligent diagnosis technology technical field. Fault diagnosis and location method uses three vibration sensors positioned on the top of transformer tank, to obtain vibration signal, uses signal processing to analyze the signal, and obtains fault characteristics of the transformer core looseness. The characteristics respectively are 50 Hz, 150 Hz and 300 Hz frequency components, in which 300 Hz is main feature. When they reach a certain value at one position, it suggests that transformer core looseness near this position. By the comparison of differences among signals of three positions, fault location can be done. This invention manifests fault characteristics accurately and detects core looseness efficiently.The invention uses the electricity grid frequency of 50 Hz for example, for 60 Hz power system, above 50 Hz, 150 Hz, 300 Hz characteristic frequencies are 60 Hz, 180 Hz and 360 Hz.
