Abstract: A method of making a single-crystalline Si wafer with an approximately polygonal cross section and having a material property that is the same as a zone-pulled Si crystal, and the single-crystalline Si wafer. The method includes pulling at least one bottle neck of a crystal vertically downwards from a rotating hanging melt drop. The rotational speed of the crystal is reduced to between 0 and less than 1 rpm. In a crystal-growth phase, a Si single crystal ingot is pulled vertically downwards with an approximately polygonal cross section. An inductor is used to generate a temperature profile at a growth phase boundary of the crystal that corresponds to the shape of a cross section of the pulled Si single crystal ingot. The growth is ended at a desired pulling length and the Si single crystal ingot is cut into wafers having an approximately polygonal cross section.

Abstract: A method for stabilizing multi-channel optical signal wavelengths includes the following steps. A first detecting signal is stacked on a plurality of driving signals in sequence. A plurality of optical signals generated after being driven by the plurality of driving signals is combined into one optical total signal. A wavelength detection is performed on the optical total signal. A second detecting signal with a frequency band the same as that of the first detecting signal is extracted from the signals obtained after the wavelength detection. The wavelength of the optical signal in the corresponding channel among the multiple channels is controlled according to the second detecting signal. A device for stabilizing multi-channel optical signal wavelengths is also provided. Using the above method or device, the multi-channel optical signal wavelengths can be stabilized, which requires less elements, and has a simple circuit structure, a high integration level, and a low cost.

Abstract: Metal induced polycrystallized silicon is used as the anode in a light emitting device, such as an OLED or AMOLED. The polycrystallized silicon is sufficiently non-absorptive, transparent and made sufficiently conductive for this purpose. A thin film transistor can be formed onto the polycrystallized silicon anode, with the silicon anode acting as the drain of the thin film transistor, thereby simplifying production.

Abstract: The described method and system allows for the utilization of a telematics unit on a telematics-equipped vehicle to prevent the unauthorized discharge of a vehicle battery. A user may communicate an authorization request for allowing discharge of the vehicle battery through a telematics unit or telematics service provider (TSP) call center. If approved by the TSP call enter or telematics unit, an authorization, which may include an authorization code, is communicated to a charge controller which controls the discharge of the vehicle battery. Alternatively, the user may communicate an authorization code directly to the telematics unit which passes it on to the charge controller for approval.
