  • Patent number: 6608470
    Abstract: A protection circuit (100) and protection device (300) for protecting a rechargeable (lithium-based) battery cell or cells from overcharging. A voltage regulator element (110, 310) is connected in parallel with the battery cell or cells (5) and is thermally coupled to a thermal element (120, 322, 326) connected in series with the charging current supply. The voltage regulator element (110, 310) prevents overcharging of the battery (5) by shunting current away from the battery when a predetermined voltage across the battery is exceeded. Moreover, the thermal element (120, 322, 326) prevents failure of the voltage regulator element (110, 310) by open circuiting the current path when the heat dissipated by the voltage regulator element (110, 310), thermally coupled to the thermal element (120, 322, 326) causes the thermal element to enter a high resistance state.

  • Patent number: 6331764
    Abstract: This invention includes a battery overprotection device comprising a thermal resistor, a zener diode, a pass element and a control circuit. The thermal resistor is used as an over-temperature limiting device, rather than an overcurrent device. By thermally coupling the thermal resistor to the zener diode, the thermal resistor protects the zener diode from “burning up” as a result of continuous power dissipation. When the zener is subjected to continuous power dissipation, its temperature rises. As the temperature rises, the thermal resistor's impedance increases, thereby reducing the power dissipation in the zener. The zener/thermal resistor combination serves as an auxiliary safety circuit for the transistor and control circuit.

  • Patent number: 5606241
    Abstract: A battery charging system includes a battery pack (106) and charger (102). Battery pack (106) includes a selectable magnetic field generator (202) which is activated by radio controller (206) when radio (104) changes states. A Hall-effect switch (204) located in either charger (102) or battery (106) receives the magnetic field and informs charger monitor circuit (128) that radio (104) has changed states. This allows for charger (102) to modify the amount of current being provided to radio (104) via line (129). In a second embodiment, an infrared source (402) and an infrared detector (404) are used in place of selectable magnetic field generator (202) and Hall-effect switch (204).

  • Patent number: 5534765
    Abstract: A battery charger system (100) is provided which includes a charger (110) for supplying charge current and voltage and a battery (120) having a memory (122) for storing charge parameters. The charge parameters comprise battery related information instructing for battery charging. The battery related information stored in the memory (122) may include charge instructions instructing the charger of procedure for charging the battery (122).

  • Patent number: 5482793
    Abstract: A battery assembly (200) includes first and second battery housings (202 and 204), a plurality of battery cells (204), and a flexible circuit having a thermal sensing surface (206) which is located in thermal proximity to battery cells (204). The thermal sensing surface (206) is in thermal proximity to the plurality of battery cells (204) providing for improved thermal sensing of battery assembly (200).

  • Patent number: 5355787
    Abstract: Taping apparatus (27) has a body (3) with a mouth (3a) opening to one side radially of an axis (A). A head (1, 5, 16) having a mouth (3a) radial of the axis (A) is mounted for rotation about the axis (A) on the body (3) and has a gear disposed around the head in meshing engagement with two gears (17) mounted on the body. The gears (17) are both in mesh with a gear (9) rotated by a gear (11) driven by motor (12) thus to rotate the head. A tape reel (28) is carried by chuck (6) rotatably disposed on an axle (8) on the head for rotation about an axis (B) parallel with the axis (A). A counterbalance (4) is mounted on the head (1, 5, 16) opposite the chuck (6) on axle (8) comprising a weight (2) movable towards and away from the axis (A) and a roller (26) urged by a spring (24) against the outermost layer (28a) of the tape on reel (28) thereby detecting the diameter of tape carried by the reel (28) thus to move the weight (2) to a position to substantially counterbalance the reel as it rotates.

  • Patent number: 5206097
    Abstract: A battery package (100) includes a transparent window (108) which communicates information about the battery to a battery-powered device such as a portable radio (200). Information about the battery (100) is communicated through the window (108) by a series of light pulses, and is received by a light sensor (340) in the radio. The information is processed by the radio microprocessor (344) and the status of the battery (100) is displayed on the radio display (346). The window (108) is gas permeable and water impermeable, serves as a vent for the battery housing (110) and also as an optical data transmission window.
