摘要:
A portable electronic device having an electrical power source, the electrical power source including at least one fuel cell adapted to receive fuel and generate therefrom electrical power for powering at least one component of the portable electronic device, a fuel tank adapted to provide fuel to the fuel cell, and at least one thermoelectric module in thermal contact with at least one of the fuel cell and fuel tank for regulating the temperature of the at least one fuel cell and at least one fuel tank.
摘要:
Systems and methods are disclosed for detecting whether a battery in an electronic device is counterfeit or defective. An actual battery characteristic profile is generated by recording the performance of the battery during use of the battery by the device. This profile is then compared to its corresponding expected characteristic profile. If the profiles are not substantially similar (i.e. if the error between the two curves exceeds a given error threshold), the battery is determined to be counterfeit or defective and responsive action is taken.

A mobile device having: a keyboard; a printed circuit board having at least one contact responsive to the keyboard; and a fuel cell assembly having: a fuel cell located between the keyboard and the printed circuit board, the fuel cell having a membrane and at least one aperture corresponding with the at least one contact; a tank adapted to store a fuel for the fuel cell; and piping connecting the tank with the fuel cell, where the fuel cell ventilates through the keyboard. Alternatively, the fuel cell acts as the printed circuit board and at least one contact for the keyboard is printed onto the fuel cell.

The disclosure is directed at a method and apparatus for controlling fuel cell operating characteristics. In certain situations, the operating efficiency of fuel cells is degraded to external conditions. Providing a method and apparatus to control operating conditions for the fuel cell assists in improving the operating efficiency. This can be achieved by controlling certain environmental conditions, such as temperature and relatively humidity, in the area surrounding the fuel cell.

An electronic accessory (300) connectable to a remote electronic device through a data interface. The electronic accessory includes an electronic circuit (320) configured to exchange data through a data interface and an optical and electrical circuit connector (106). The optical and electrical circuit connector includes a connector body (106) configured to engage a corresponding connector (104), at least one optical terminal (130, 131, 133, 135) for the data interface coupled to the connector body, and at least one electrical data interface terminal (182) for the data interface coupled to the connector body. In one embodiment an inner (550) and an outer conductive ring (552) conduct electrical power.

The connector body has an inner portion (510) and an outer portion (550, 520, 522, 524, 526, 530, 532, 552, 554), at least one optical terminal (520, 522, 524, 526) for the data interface disposed within the outer portion, at least one electrical data interface terminal (510) for the data interface disposed within the inner portion. The connector body further has at least one magnetic attachment area (530, 532) disposed within the outer portion that magnetically attaches the connector body to the corresponding connector.
摘要:
A method and system for detecting the use of an unauthorized battery pack in a portable electronic device. The method comprises monitoring a temperature profile of at least one battery cell in a battery pack during an operation of the portable electronic device. The temperature profile is determined in accordance with an output of an internal temperature sensing circuit in the battery pack. If the temperature profile is determined to be atypical, an indication is provided that the battery pack is an unauthorized battery pack. For example, if the temperature profile does not show an expected temperature rise during a charging operation, a visual indication can be provided. The indication can also trigger the control of charging or discharging operations of the portable electronic device. Charging can be terminated or the device shut down to avoid a potentially catastrophic thermal runaway event. The device can also be operated in a reduced power mode in response to the indication.
