    • A method of analyzing a limited rotation motor system is disclosed. The method includes the step of providing a motor control frequency domain signal that is representative of a frequency domain representation of the motor control signal responsive to a first digital signal that is representative of a motor control signal. The method also includes the step of providing a position detection frequency domain signal that is representative of a frequency domain representation of the position detection signal responsive to a second digital signal that is representative of a position detection signal. The system further includes the steps of identifying a representation of the frequency response of the limited rotation motor responsive to the position detection frequency domain signal and the motor control frequency domain signals, and comparing the representation of the frequency response with a previously recorded representation of a prior frequency response to identify an error condition with respect to the limited rotation motor system.

    • A poly fuse trim cell includes a poly fuse and a transistor connected together at a first node; the transistor conducts a current necessary to blow the fuse in response to a control signal. The cell also includes a switching transistor, connected between the first node and a current source circuit. A logic gate is connected to the first node at one input, and to a reset signal at a second input. The output of the logic gate provides the trim cell's output, and controls the switching transistor. When the fuse is intact, the logic gate output is “low” such that the switching transistor is off and the cell's quiescent current is zero. When the fuse is blown, the logic gate output goes “high” upon the occurrence of a reset signal, which turns on the switching transistor and allows the current source circuit to pull down the first node.
    • 多熔丝修整单元包括在第一节点处连接在一起的多晶硅熔丝和晶体管; 晶体管响应于控制信号导通熔断器所需的电流。 电池还包括连接在第一节点和电流源电路之间的开关晶体管。 逻辑门在一个输入处连接到第一节点,并在第二输入端连接到复位信号。 逻辑门的输出提供微调单元的输出,并控制开关晶体管。 当保险丝完好时,逻辑门输出为“低”,使得开关晶体管截止,电池的静态电流为零。 当保险丝熔断时,逻辑门输出在复位信号发生时变为“高”,导通开关晶体管,并允许电流源电路拉下第一个节点。

    • The present invention relates to a home gateway device. The home gateway device comprises a main processor generate information process signals and control signals, a computer bus signal Ethernet adapter unit connected to the main processor to translate the signals between computer bus signals and Ethernet signals, an Ethernet frame process unit connected to the computer bus signal Ethernet adapter unit to forward the received Ethernet frame based on a prearranged policy, an inner interface unit connected to the Ethernet frame process unit to connect interior networking devices, and an outer communication module connected to the main processor and the Ethernet frame process unit. The centralized control of the home gateway device of the present invention can decrease the requirement that the household appliances should be intellectualized, thereby achieving more flexible control and reducing the cost. The uplink and downlink Ethernet signals are controlled by using the prearranged policy to separate the Ethernet signals for Internet access from the Ethernet signals of the household information appliances, and avoid the threat due to the unsafe factors.
