Abstract: A method for controlling power consumption by an electricity storage apparatus is provided. The method includes receiving, from a utilizing side, an inquiry request signal for inquiring whether power supply from the electricity storage apparatus is possible, inquiring an amount of charged power from the electricity storage apparatus compared to a capacity of the electricity storage apparatus, comparing a required amount of power, which is included in the inquiry request signal, with the amount of charged power, and based on the comparison result, determining an amount of power to supply to the utilizing side and whether to switch to an operation mode of supplying the amount of power to the utilizing side, and upon determining to switch to the operation mode, checking an amount of available supply power in accordance with the operation mode, and transmitting information about the checked amount of available supply power to the utilizing side.

Abstract: Provided is an apparatus for controlling multiple powers which is capable of turning on and off the multiple powers in their priorities for systems or components to be supplied with the multiple powers such as a liquid crystal display (LCD) module. In the apparatus for controlling multiple powers, an on-signal of high level is applied to an input terminal, and an output of a control signal generating unit is sequentially changed to a high level whenever a clock is applied to a clock signal input terminal by one period, so that outputs of the multiple powers are sequentially output. In addition, an off signal of low level is applied to the input terminal, and an output of the control signal generating unit is changed to a low level in a reversal order whenever a clock is applied to the clock signal input terminal by one period, so that outputs of the multiple powers are interrupted in the reversal order.

Abstract: Provided is a programmable variable-length decoder that interfaces with an external processor. The programmable variable-length decoder includes a memory buffer, a latching unit, a multiplexing unit, a first barrel shifter, a decoding unit, and a control unit. The memory buffer stores input serial bit stream data for decoding in fixed-length data segments and outputs the stored bit stream data in response to a first control signal. The latching unit temporarily stores data output from the memory buffer and outputs the stored data in response to the first control signal. The multiplexing unit selects data from the latching unit and outputs the selected data. The first barrel shifter shifts the output of the multiplexing unit by the value of a second control signal and outputs the shifted data. The decoding unit decodes the output of the first barrel shifter and outputs decoded codewords and the bit length of the decoded codewords.
