Filed:

Dec 6, 2011

Appl. No.:

13/311899

Inventors:

David Gerard RICH - West Bloomfield MI, US
Chee-Ming Jimmy WU - Waterloo, CA

Assignee:

RESEARCH IN MOTION LIMITED - Waterloo

International Classification:

H02J 1/00
H01M 8/04

US Classification:

307 80, 429433, 429442, 429428

Abstract:

The disclosure is directed at a fuel cell recovery time system for a mobile communication device including a battery for supplying power to the mobile communication device when the device is in a stand-by mode; a fuel cell element including at least two fuel cells, one of the at least two fuel cells being always on and the remaining fuel cells being off in the stand-by mode; wherein the one of at least two fuel cells generates heat to improve operating conditions for the remaining fuel cells in the fuel cell element when the device enters an active mode.

Matthew Michael Ignor - Stratford, CA

International Classification:

G01K 13/00

US Classification:

702130

Abstract:

According to one aspect, a portable electronic device having a heat generating component, a thermal sensor, an energy storage device for powering the portable electronic device, a thermal element thermally coupled to the heat generating component, the energy storage device, and the thermal sensor. The thermal element is sized and shaped so that heat generated by the heat generating component flows through the thermal element towards the thermal sensor and interacts with the energy storage device. The thermal sensor is used to monitor a thermal profile for the thermal element, and the monitored thermal profile is compared with an expected thermal profile to determine if the integrity of the portable electronic device has been compromised.

International Classification:

G08B 29/00

US Classification:

340 58

Abstract:

Various embodiments of devices and associated methods are described herein for authenticating electrical devices. In one aspect, an electrical device is provided comprising an interface configured to receive and transmit signals; a power line coupled to the interface and configured to provide a power signal thereto; and an authentication circuit coupled to the interface and the power line. The authentication circuit is configured to disable the power signal on the power line for a specified time period in response to an authentication request signal received at the interface and to provide an authentication response signal on the power line to represent the disabling of the power signal.
