Abstract: A battery system including a plurality of battery cells, a lower controller configured to collect cell voltages of the plurality of battery cells at each sampling period of a plurality of sampling periods, calculate, based on the cell voltages, an average cell voltage and cell voltage deviations, encode the cell voltage deviations into first bit codes by using a first cell voltage Huffman code table, and transmit the average cell voltage and the first bit codes at each sampling period of the plurality of sampling periods, and an upper controller configured to receive the average cell voltage and the first bit codes from the lower controller, decode the first bit codes into decoded cell voltage deviations by using a second cell voltage Huffman code table, and generate restored cell voltages of the plurality of battery cells by using the average cell voltage and the decoded cell voltage deviations.

Abstract: An electronic device includes a housing, a display module having a first region, a second region and a third region between the first region and the second region. The display module comprises a window including a first portion having a first thickness in the first region, a second portion having a second thickness in the second region, the second thickness being less than the first thickness, and a recessed portion in the third region. The display module comprises an adhesive member disposed on at least one surface of the window. The display module comprises a display panel attached to the window. The recessed portion has a first radius of curvature between the first region and the third region, a second radius of curvature between the second region and the third region, and a third radius of curvature at a point having a minimum thickness in the recessed portion.

Abstract: A battery pack includes: a plurality of battery blocks, each including a plurality of battery cells; a plurality of analog front ends (AFEs) sequentially located, and to monitor states of the plurality of battery blocks, respectively; a main management unit to communicate with the plurality of AFEs; and a power compensation circuit connected to a highest stage AFE from among the plurality of AFEs, and including a power compensation resistor and a power compensation switch connected in series with each other. The highest stage AFE includes: a power circuit to generate a driving voltage from a block voltage of a highest stage battery block from among the plurality of battery blocks; a pair of output voltage pins to output the driving voltage to the power compensation circuit; and a global purpose input output pin (GPIO) to output a power compensation control signal to control the power compensation switch.

Abstract: Discussed are an LCD device and a method of driving the same in which, by decreasing the number of lines of a PCB, the manufacturing cost is saved, and the influence of noise is reduced.
