Abstract: An energy storage device includes an integrated fuel gauge that is operatively connected to the energy storage device. The fuel gauge evaluates an operating parameter of the energy storage device and dynamically determines a state of charge. The fuel gauge communicates a communication including a requested operating parameter to the charging component with the single communication line and the signal indicates to an operating system component a change of an energy storage device state. The signal is used to trigger an alert or interrupt that causes the operating system component to display the change of the energy storage state based on the signal.

Abstract: An energy storage device includes an integrated fuel gauge that is operatively connected to the energy storage device. The fuel gauge evaluates an operating parameter of the energy storage device and dynamically determines a state of charge. A charging component is coupled to the energy storage device with a single communication line. The fuel gauge communicates a communication including a requested operating parameter to the charging component with the single communication line according to a predetermined charge profile based on the state of charge determined.

Abstract: A system comprises a battery cell, control logic, and a battery drain latch circuit. The control logic is coupled to the battery cell and determines whether a battery pack has experienced a failure condition. The battery drain latch circuit is activated by the control logic, upon detection of a failure condition, to cause the battery cell to drain energy therefrom.

Abstract: Methods and apparatus for recharging a rechargeable battery (202) having step charge requirements, where the charge current is tapered as successive voltage thresholds of the step charge requirements are approached. The battery (202) is programmed with a charge tapering algorithm, so that the battery charger (208) need not be programmed with battery-specific information. The charge tapering algorithm is used in conjunction with the step charge requirements and a measurement of one or more properties of the battery to determine an appropriate charge current as a function of time.

Abstract: A multipurpose firefighting and demolition implement is disclosed. The implement uniquely combines the functions of at least three or more of the following: an axe, a shovel, a hoe, a pry bar, a hook, a claw, and a socket into one compact, toteable implement for use in firefighting and demolition. The implement comprises a dual-sided head with a handle mount in the middle. The front side of the head comprises a substantially flat front blade with a toothed edge on the edge of the blade opposite the handle mount. The front blade may also comprise a socket. The other side of the head comprises an axe blade. The axe blade includes a notched portion on either the upper surface, the lower surface, or on both of the upper and lower surfaces of the axe blade.

Abstract: The method first defines a population for Product Cash Revenue and a population for Product Lease Revenue and calculating the mean, median, and variance of the populations and determining therefrom the normality of each of the distributions. Next, the variances of each of the distributions are compared for equivalency by a Homogeneity of Variance test. If each of the distributions are not normal and the variances are not equal then the fair market value is not determinable. Otherwise, if each of the distributions are not normal and the variances are equal then the method further comprises determining if the medians of each of the distributions are equivalent by Mann-Whitney. If the medians of each of the distributions are not equivalent then the values of the leases are adjusted by the lowest constant in whole dollars until the means of each distribution are equivalent.
