Patent number: 6459237Abstract: A charger for a battery includes a power source and a control circuit. The battery has an internal resistance, at least one cell having a recommended charge voltage, and an aggregate recommended charge voltage. The power source is capable of providing an applied voltage and charge current to the battery. The control circuit is connected to the power source and is capable of detecting the applied voltage of the battery and enabling the charge current and applied voltage to the battery until the applied voltage is greater than the aggregate recommended charge voltage by an amount less than the product of the internal resistance and the charge current. The control circuit is capable of reducing the applied voltage towards the aggregate recommended charge voltage at a controlled rate such that the recommended charge voltage of the at least one cell is not exceeded.Type: GrantFiled: June 13, 2000Date of Patent: October 1, 2002Assignee: Hewlett-Packard CompanyInventor: James F Bausch

Patent number: 6449575Abstract: A method and apparatus for operating an integrated circuit in an electronic device by controlling the supply voltage to the integrated circuit (IC). A parameter of the IC is measured and used to adjust the supply voltage of the IC. The measured parameter is indicative of the effective channel mobility of the IC. One purpose of adjusting the voltage is to modify the effective channel mobility such that the individual channel currents are substantially constant over a predetermined operating temperature range of the IC. The modification of channel mobility is chosen to set the individual channel currents at levels that either maximizes operating speed, minimizes power consumption, extends the range of operating temperature, or increases the operational reliability of the IC.Type: GrantFiled: July 13, 2001Date of Patent: September 10, 2002Assignee: Hewlett-Packard CompanyInventors: James F.

Patent number: 6191546Abstract: An electronic device has a heat producing component thermally coupled to a heat dissipation structure. The electronic device further has control circuitry connected to a temperature sensor that senses the component temperature of the heat producing component. The control circuit is further connected to a cooling device also thermally coupled to the heat dissipation structure. The control circuit varies the cooling rate in a manner that cancels out a lag time which occurs during a change from a steady state condition of the component temperature. The cooling rate of the cooling device is varied by the control circuit in proportion to variation in sensed component temperature from the temperature sensor.Type: GrantFiled: October 1, 1999Date of Patent: February 20, 2001Assignee: Hewlett-Packard CompanyInventors: James F.
