  • Patent number: 7728552
    Abstract: A battery management system is disclosed for control of individual cells in a battery string. The battery management system includes a charger, a voltmeter, a selection circuit and a microprocessor. Under control of the microprocessor, the selection circuit connects each cell of the battery string to the charger and voltmeter. Information relating to battery performance is recorded and analyzed. The analysis depends upon the conditions under which the battery is operating. By monitoring the battery performance under different conditions, problems with individual cells can be determined and corrected.

  • Patent number: 7479764
    Abstract: A battery monitor for use with a battery includes an input configured to receive a voltage from the battery, an analog to digital converter (ADC) coupled to the input and configured to convert analog voltages received through the input into digital indications of levels of the analog voltage, and a processor coupled to the ADC to receive the digital indications of the levels of the analog voltage of the battery and configured to manipulate the received digital indications to reduce inaccuracies introduced by the ADC in the received digital indications of the levels of the analog voltage relative to actual levels of the analog voltage during discharge of the battery, the processor being further configured to provide an output indicative of a determined level of the analog voltage.

  • Patent number: 4124208
    Abstract: A hockey stick having opposed metal outer skins of continuous one piece including integral handle and blade portions with a metal honeycomb sandwiched therebetween. An adhesive secures the metal honeycomb to the inner surfaces of the metal outer skins, and a filler encloses the side edges of the stick between the metal outer skins. An expandable foam adhesive is disposed in the metal honeycomb portion between the metal outer skins along the blade portion, and is disposed in the honeycomb portion between the metal outer skins along the handle portion adjacent the blade portion. The edge filler is a plastic extending between and adhering to the inner surfaces of the metal outer skins and adhering to and filling the sides of the metal honeycomb.
