  • Publication number: 20100033137
    Abstract: A rapid charging circuit for a lithium ion battery. The battery charger in accordance with the present invention compensates for the voltage drops across the various resistance elements in the battery circuit by setting the charging voltage to a level to compensate for the initial resistance of the series resistances in the circuit and an additional resistance selected to take into account the anticipated increase in resistance of the various circuit elements over time. The battery charger in accordance with the present invention periodically monitors the open-circuit voltage of the battery cell and reduces the charging voltage to when the battery cell voltage reaches the optimal value. Thus, during a constant current charging mode, the battery cell is driven at a relatively optimal charging current to reduce the charging time.

  • Patent number: 7556882
    Abstract: A battery housing unit with a releasable cover for minimizing mis-alignment of a battery housed therein during high impact loads. The battery unit includes a battery holder having retention members biased towards one another that receive a battery. The retention members engage stop ribs projecting from the cover. The cover fits over the retention members of the battery holder and to a base of the housing unit. The retention members and stop ribs are engaged when high impact loads are delivered to the housing unit and the battery is urged against the biasing nature of the retention members. Movement and mis-alignment of the battery is thus minimized and high impact loads are re-distributed throughout the cover. Detents may be provided on each retention member for engaging a corresponding cavity provided on each stop rib. The detents and cavities interlock the retention members and stop ribs together upon high impact. In this manner, movement and mis-alignment of the battery is also minimized.

  • Patent number: 7528717
    Abstract: A tamper detection mechanism in a sensor device comprising a body and a mounting base. The sensor device includes a substantially central resilient element/plunger attached to the mounting base. The body houses a printed circuit board includes a surface for mating to the resilient element to create a circuit. The mounting base may be removably affixed to a structure such as a wall or ceiling. When the mounting base is screwed into the structure and the body is coupled to the mounting base, the plunger is compressed and exerts a continuous pressure on the printed circuit board surface to complete the tamper circuit. If the sensor device is uncoupled and/or removed from the structure, the circuit is opened and a tamper indication signal is produced.
