Abstract: A lithium-ion battery (126) is normally charged using a constant current/constant voltage charge regime (206, 210), where the battery is charged to a preselected normal voltage level (210) whereupon the voltage is maintained at the limit while the charging current diminishes. The battery charge capacity can be selectively increased by charging the battery to an enhanced voltage level (212). The enhanced charging mode is selected by a user via a device user interface (112), or alternatively by a broadcast command (304) transmitted to the device.

Abstract: A lithium-ion battery (126) is normally charged using a constant current/constant voltage charge regime (206, 210), where the battery is charged to a preselected normal voltage level (210) whereupon the voltage is maintained at the limit while the charging current diminishes. The battery charge capacity can be selectively increased by charging the battery to an enhanced voltage level (212) and it can recorded that the battery voltage passed the normal voltage limit. The enhanced charging mode is selected by a user via a device user interface (112), or alternatively by a broadcast command (304) transmitted to the device.

Abstract: A portable electronic device and a method to protect the portable electronic device from a battery bounce are provided. The portable electronic device (100) can comprise a free-fall condition sensor (105) enabled to detect a pre-battery bounce condition in the portable electronic device and a processor (110) coupled to the free-fall condition sensor (105). The processor (110), in response to a detection of the pre-battery bounce condition by the free-fall condition sensor (105), can be programmed to place the portable electronic device (100) in a pre-battery bounce setting. The method can include detecting a pre-battery bounce condition in the portable electronic device (405) and in response to the detection of the pre-battery bounce condition (405), placing the portable electronic device in a pre-battery bounce setting (410).

Abstract: A system (200) includes a battery charger (278) and a battery (202). The battery (202) includes a thermistor (230), a voltage identifying element (240), a switch (244), a memory device (232), and a battery data contact (228), connected to a data port of the memory device (232) and the voltage identifying element (240). The voltage identifying element (240) determines a voltage that controls the switch (244). When the switch (244) is enabled, the thermistor (230), connected to a battery clock contact (224), is active and a microprocessor (102) on the battery charger (278) reads the value of the thermistor (230) via an analog-to-digital converter. When the switch (244) is disabled, the thermistor (230) is switched out and the battery clock contact (224) is used to clock the memory device (232). The battery charger (278) has a data contact (226) for receiving the battery data contact (228) and a clock contact (222) for receiving the battery clock contact (224).

Abstract: A system for verification of a battery (100) includes the battery (100) and a device (400,500). The battery (100) includes a memory device (135) for storing an identification number and a verification number. The verification number is generated by applying a key to the identification number. The device (400,500) is coupled to the battery (100) and includes a device memory (515) for storing the key and a microprocessor (435,510) for verifying the identification number of the battery (100) by applying the key to the verification number.

Abstract: A battery charging system (250) for use with an induction charger (210). The battery charging system can include a secondary coil (252) having a plurality of turns for receiving magnetic flux produced by a primary coil (220) of the induction charger, and a control circuit (254) for controlling a number of turns of the secondary coil that are used in generating an output voltage for charging a cell (264). For example, the secondary coil can include a plurality of taps (291, 292, 293, 294), each of the taps providing an electrical connection to the coil at a different point, and thus providing a variety of selectable output voltages.

Abstract: Adjustable bifocal spectacles having at least one pair of lenses mounted in an upper frame vertically movable in relation to a lower frame so that the focal length may be changed by raising and lowering a pair of lenses in the sight line of the viewer. Means are provided for applying a pressure to the upper and lower frames either at opposite ends of the frames or at the nose support and bridge to raise or lower the upper frame in relation to the lower frame, the pressure being symmetrical with respect to the nose and bridge. Vertical movement of the lenses is accomplished by actuating a mechanism at one side or at opposite sides of the lens frame, either mounted directly to the lens frame or mounted in modified temples so that the spectacles may be adjusted without placing the hand in front of the face.

Abstract: A means is shown for delivering a prescribed liquid medicine or other fluid to a subcutaneous tissue. The device includes a reservoir on the outside of the body for holding a supply of the prescribed liquid, the reservoir being adhesively attached to the skin near the tissue to be treated. The reservoir feeds the liquid to absorbent or capillary wicks adapted to pass through the skin to be installed in the subcutaneous tissue to which the fluid is to be fed. The wicks may be provided in several forms such as twisted or braided suture material, the ends of which, in some instances, may be encased in plastic. The wicks, in whatever form, are guided from the outside into their installed positions in the subcutaneous tissue with conventional cutting or tapered surgical needles, and in the modification making use of a plastic casing, a slightly modified needle is used to install the wick cover.
