A peripheral device and a method for operating a peripheral device is disclosed. The peripheral device includes one or more connection mechanisms for coupling to a computing device, a power supply, and a controller. The controller is configured to enable the peripheral device to communicate with the computing device. When the peripheral device is coupled to the computing device, the controller is configured to determine the amount of power remaining in the power supply of the peripheral device, and based at least in part on the amount of power remaining in the power supply of the peripheral device, enable the peripheral device to charge a power supply of the computing device, and enable the peripheral device to receive power from the power supply of the computing device.

Power sharing between portable computer system and peripheral devices

A method and apparatus that allows for controlling operating time of a portable computer system and a peripheral device. A portable computing system that includes a rechargeable power supply and that includes a connection mechanism for coupling to a peripheral device is used to control operating time of the portable computer system and the peripheral device. In one embodiment, a user can choose between maximizing the operating time of the portable computer, maximizing the operating time of the peripheral device, or maximizing the life of the entire system (maximizing the operating time of the portable computer system and the peripheral device). When operating time of the portable computer system is to be maximized, power is sent from the peripheral device to the portable computer system to extend the operating time of the portable computer system. Similarly, when operating time of the peripheral device is to be maximized, power is sent from the rechargeable power supply of the portable computer system to the peripheral device to extend the operating time of the peripheral device. When operating time of the entire system is to be maximized, power is moved such that the operating time for the portable computer system is equal to the operating time of the peripheral device.

Power sharing between portable computer system and peripheral device

An information storage and transmission device which captures handwritten and digital data relating to various financial transactions and stores the information when the transactions are made. The device can then wirelessly transmit this information to different terminal units, such as host PCs, ATMs, or terminal units used for point-of-sale transactions in order to facilitate the financial transaction and help a user track his financial transactions in an easier manner.
