摘要:
Charging systems (10, 70) are disclosed that generally employ forces generated by at least one magnet (16–22) or (76–82) to guide and urge a rechargeable, portable or mobile electronic device (12, 72) toward a charging position with respect to a charging base (14, 74) therefor. By using magnetic forces to guide or urge the device (12, 72) to the charging position, substantially frictionless charging systems (10, 70) can be provided herein for shifting the device (12, 72) to its charging position. Either repulsion or attraction forces can be employed. Accordingly, depending on which magnetic force is used to urge the device (12, 72) to its charging position, an opposite magnetic force is preferably provided to provide the user a tactile indication of improper alignment of the device (12, 72) and charging base (14, 74). Preferably, pairs of opposite single pole magnets are used so that there is one pair (16, 18) or (76, 78) associated with the device (12, 72) and another pair (20, 22) or (80, 82) associated with the base (14, 74).
摘要:
A portable communication device (10) includes a transceiver (12 and 14), an acceleration sensor (20) coupled to the transceiver, and a processor (16) coupled to the acceleration sensor. The processor is programmed to monitor (32) an acceleration profile of the portable communication device and compare (48 and 52) the acceleration profile of the portable communication device with at least one pre-stored acceleration profile (18).
摘要:
A portable (travel) charger or power adaptor (10) can minimize the protrusion from a wall when used as a wall mounted charger and can further maximize the number of power adaptors that can be (safely) plugged into a standard AC strip. The power adaptor can include a housing (12) containing a power transformer and a pair of pivoting prongs (13 and 15) forming a plug (14) arranged to be substantially near a top portion of the housing. The pair of pivoting prongs in a first position or horizontal position can make the adaptor suitable or configured for coupling to an AC wall outlet receptacle and in a second position or vertical position can make the adaptor suitable or configured for placement in an AC strip receptacle (22) of a standard power strip (20).
