Abstract: A battery management system and a method for enhanced battery management of a battery containing a number of cells. The method and system measures the cell capacity of two or more of said cells, ranks the cells in order of their cell capacity values and calculates a value for a cell specific supporting current for the measured cell, for a given load, based upon the ranked cell capacity values. Calculated cell specific currents are then provided to the cells.

Abstract: Apparatus and method for battery calibration and state of charge determination (SoC) within battery packs by detecting charge levels in a cell or cells, sending the charge level information to a controller which controls the movement of charge in the battery wherein, the controller initiates the discharge of a sub-unit to a predetermined level into the other sub-units and the charging of said sub-unit in the battery to a predetermined level from the charge held on the other sub-units to improve the accuracy and reliability of battery calibration and provide an accurate State of Charge indication from battery first use to end of life.

Abstract: A display apparatus: a display screen on which a display drive generates a picture in response to picture information (R,G,B,H.V) from a video source connected via a releasable connector to the display apparatus. User controls adjust the picture generated by the display drive in response to a manual input. Selection controls are included for selecting one of a plurality of sets of control data for communication to the video source in response to a configuration code input via the user controls.

Abstract: A high power supply ripple rejection internally compensated low drop-out voltage regulator using an output PMOS pass device. The voltage regulator uses an intermediate amplifier stage configured from a common source, current mirror loaded PMOS device to replace the more conventional source follower impedance buffer associated with conventional Miller compensation techniques. Compensation is achieved through use of a small internal capacitor that provides a very low frequency dominant pole at the output of the input stage while effectively pushing out the two other poles at the outputs of the second and third gain stages to a frequency well outside of the unity gain frequency to ensure closed loop stability. High, wide bandwidth PSRR is achieved through an integrated circuit implementation of three voltage gain stages compensated by a nested active Miller compensation technique that does not impedance shunt the output series PMOS pass device.
