  • Patent number: 8269641
    Abstract: A vehicle power management system (VPMS) controls a charging voltage of a battery in a vehicle, wherein a VPMS controller evaluates state-of-charge (SOC), battery temperature, and battery charging current to determine a charge mode. A rapid charge mode is used when the SOC is less than a first threshold, wherein the VPMS controller selects a target rapid charge voltage, compensates the target rapid charge voltage for the battery temperature, and transmits the compensated rapid charge voltage to the charging source. A normal charge mode is used when the SOC is greater than the first threshold and less than a second threshold, wherein a target normal charge voltage is selected and compensated which is less than the target rapid charge voltage. A trickle charge mode is used when the SOC is greater than the second threshold, wherein a target trickle charge voltage is less than the target normal charge voltage.

In the radio field intensity measurement device, a battery is provided as a power source for power supply and the battery is charged by a received radiowave. When a potential of a signal obtained from the received radiowave is higher than an output potential of the battery, the power is stored in the battery. On the other hand, when the potential of the signal obtained from the received radiowave is lower than the output potential of the battery, power produced by the battery is used as power to drive the radio field intensity measurement device. As an element to display the radio field intensity, a thermochromic element or an electrochromic element is used.

A pair of voltage input nodes NCk and NCk-1 is selected from voltage input nodes NC0-NCn in switch part 10, and they are connected to sensing input nodes NA and NB in two types of patterns with different polarity (forward connection, reverse connection). Sensing input nodes NA and NB are held at reference potential Vm by voltage sensing part 20, and current Ina and Inb corresponding to the voltage at voltage input nodes NCk and NCk-1 flows to input resistors RIk and RIk-1. Currents Ina and Inb are synthesized at different ratios in voltage sensing part 20, and sensed voltage signal S20 is generated according to the synthesized current Ic. Sensed voltage data S40 with low error is generated according to the difference between the two sensed voltage signals S20 generated in the two connection patterns.

  • Patent number: 7382270
    Abstract: An apparatus supporting both identification of a battery type and communications over an interface between a battery and an electronic device is disclosed. The electronic device includes a processor for communicating with communications circuitry of the battery. Identification circuitry associated with the processor enables a determination of the type of battery with which the electronic device is connected. If a “smart” battery capable of carrying out serial communications with the electronic device is connected, the electronic device further provides means for carrying out communications between the processor and the communication circuitry of the battery.

  • Patent number: 7376487
    Abstract: Disparate robotic devices can be automatically recharged and reprogrammed by self-scheduling individual time slots for the available recharging area(s) of a charging station. These charging stations provide a nest to which each robot must return periodically for power. These nests can also provide new tasking or patches for the robotic devices. The charging station and the robotic devices are both provided with communications capabilities and a protocol by which they can negotiate to find a time slot in which the device can be recharged, as well as determining a correct connector and a battery type.

  • Patent number: 7339485
    Abstract: Disclosed is a rectifier for supplying double voltage and an RFID tag thereof. The rectifier includes a charging part for charging an input voltage induced to input ends by a received radio frequency (RF) signal; a power provider for charging a sum voltage corresponding to the sum of the input voltage induced to the input end and the voltage charged in the charging part as a power voltage, and discharging the charged power voltage to provide a direct current (DC) power; and a switching part for switching to supply the input voltage induced at the input ends to the charging part during a first interval and switching to supply the sum voltage to the power provider during a second interval. Accordingly, double voltage can be supplied to other electric elements formed in the RFID tag and overcurrent caused by overvoltage can be prevented from flowing into the elements.

  • Patent number: 7123155
    Abstract: A method and an electronic device monitor a battery of the device with respect to device operational mode in one or both of battery charge level monitoring and battery cut-off determination. Mode-based monitoring employs a mode-specific wait period prior to performing a measurement used to determine a remaining charge level of a battery. The mode-specific wait period depends on the operational mode immediately preceding the measurement and therefore, accounts for battery recovery effects on measurement accuracy. Mode-based cut-off determination employs information regarding an impending operational mode to determine whether or not a remaining charge level of the battery is sufficient to support the mode. Only those operational modes for which there is sufficient remaining charge are enabled while operational modes for which there is insufficient remaining power are disabled.
