摘要:
Exemplary embodiments are directed to wireless power transfer. A power transmitting device is attached to an existing furniture item or is embedded in a host furnishing. The power transmitting device includes a transmit antenna to wirelessly transfer power to a receive antenna by generating a near field radiation within a coupling-mode region. An amplifier applies a driving signal to the transmit antenna. A presence detector detects a presence of a receiver device within the coupling-mode region. The presence detector may also detect a human presence. An enclosed furnishing detector detects when the furnishing item is in a closed state. A power output may be adjusted in response to the closed state, the presence of a receiver device, and the presence of a human.

A battery cell balancing method and apparatus. A simple and inexpensive method and apparatus to balance the cells within a battery configuration where at least some of the cells are arranged in series or a combination of series and parallel. One embodiment balances the cells proportionally to the level of imbalance between the cells. This embodiment is adaptable to more than two cells in series. Another embodiment balances the cells with a constant current. This embodiment will more quickly balance the cells because of the constant current. Components are selected in specific positions to reduce the current draw of the circuit and the effect on the system. The invention injects current into or withdraws current from a position between series cells to be balanced based on whether the voltage is higher or lower than the fractional voltage needed for the cells to be in balance.

A handheld electronic device comprises a housing around which a plurality of input keys is disposed. The input keys are placed around the housing at locations where fingers will naturally land when the handheld device is being held in an average-sized hand. An interfacing and processing unit is coupled to the plurality of keys and responds to actuation of a selected combination of at least one key by generating data representing a character. In one embodiment the processing unit is arranged to control the display to display an indication of characters that will be input if a combination of one or more input keys is actuated by the user.

A battery pack having a battery pack controller that combines the functions of a battery pack protection circuit, battery charger, current and voltage regulator, and a data monitor circuit. In one embodiment, the battery pack controller is implemented as a single integrated circuit (IC). In another embodiment, two external field effect transistors (FETs) are used along with a single IC battery controller. This combination of functions within one IC allows battery pack manufacturers to construct inexpensive and safe battery pack systems that do not require an external charger or a carefully regulated DC power supply to charge the battery pack. In one embodiment a voltage regulator includes a pulse charging circuit for pulse charging the batteries within the battery pack. Advantageously, the battery pack controller further includes a current regulator that regulates a charge current flowing into the first battery cell. The current regulator advantageously may include a means for trickle charging the battery cell. The battery pack controller also provides a processor interface that receives predetermined messages from and transmits data to an external processor, a charge termination means for terminating a charge current flowing into the first battery cell, and a discharge termination means for terminating a discharge current flowing out of the first battery cell. The battery pack controller monitors the battery and sends information concerning the battery to the external processor. This allows external processor to accurately terminate charge to the battery.
