摘要:
A charger (2) has two or more separate charging ports (8, 10) to which two or more rechargeable batteries (5, 6) can be coupled, respectively. Current from a single current source (28) is allocated to the two or more separate charging ports (8, 10) so that the two or more rechargeable batteries (5, 6) will be fully charged at substantially the same time

Various embodiments are provided herein for a connector that can provide electrical and mechanical coupling between first and second objects. The connector generally comprises at least one connecting element that has at least one first and second contact portion, at least one guidance portion located towards the end of the at least one connecting element and adjacent to one of the at least one first and second contact portions; and a biasing portion that is adjacent to the at least one first and second contact portions. The biasing portion is configured to provide an electrical connection between the at least one first and second contact portions and to resiliently move the at least one connecting element from a first position to a second position to provide a mechanical coupling force to the first and second objects.

A mobile device (104) communicates wirelessly with a smart card reader (102) to obtain identification of a person (100, 110, 120, 130) whose smart card (106, 116, 126, 136) is coupled to the smart card reader (102). The mobile device (104) transmits the identification to a server (142) via a network. The mobile device (104) also transmits information about its location to the server (142). The server (142) determines the identity and location of the person (100, 110, 120, 130) that is using the mobile device (104).
摘要:
A mobile device comprising: a hard disk (305,310); a motor (302) for spinning the hard disk; and a system for regenerating energy using the hard disk. The system (325) for regenerating energy using the hard disk may include: a switch (325) connected to the motor such that when the switch is in a first position, power flows from a power storage device to the motor to drive the motor and when the switch is in a second position, power flows from the motor based on kinetic energy of the spinning hard disk to the power storage device. The system for regenerating energy using the hard disk may be manufactured/combined with the hard disk and motor separately from the mobile device such that the system for regenerating energy may include the hard disk and motor.
