  • Publication number: 20200203990
    Abstract: A power switching circuit receives a first power, a second power and a switching signal, and generates an output power. The power switching circuit includes a first power path and a second power path. The first power path is connected with the first power. The second power path is connected with the second power. When the switching signal in a logic high level, the first power path is in a conducting state and the second power path is in a non-conducting state. Consequently, the first power is selected as the output power by the power switching circuit. When the switching signal in a logic low level, the first power path is in the non-conducting state and the second power path is in the conducting state. Consequently, the second power is selected as the output power by the power switching circuit.

  • Patent number: 10690588
    Abstract: A material transport property measurement system includes an ellipsometry system, a heat capacity measurement system, and a controller. The ellipsometry system has a light source to generate a light which passes through a polarizer and shines on a sample. The sample reflects the light to an integrated polarization analyzer, which includes multiple polarizers with different polarization angles distributed from 0 to 180 degrees. A detector assembly includes multiple detectors corresponding to the multiple polarizers to detect light passing through the respective polarizers and generate multiple first electrical signals. The heat capacity measurement system measures a temperature parameter of the sample using a non-contact method, and outputs a second electrical signal. The controller analyzes the second and the multiple first electrical signals to obtain the transport properties of the material. A material transport property measurement method is also provided.

  • Patent number: 10667278
    Abstract: Various embodiments provide for the management of wireless resources, which can reduce call blocking by allowing high priority services, under suitable conditions, to use resources allocated to low priority services. Thus high priority services can pre-empt the usage of wireless resources by low priority services. This has the advantage of reducing call blocking for high priority calls, while permitting low priority calls to have more access to radio resources than conventional systems with the same call blocking rate. Thus a base station can implement a preemption mechanism that would reclaim Walsh Code and Forward Power resources from an active Supplemental Channel (SCH) burst in order to accommodate incoming Fundamental Channel (FCH) requests.
