Filed:

Jul 29, 2003

Appl. No.:

10/628610

Inventors:

Jason N. Howard - Alpharetta GA, US
Hossein Maleki - Lawrenceville GA, US

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H02J007/16

US Classification:

320150

Abstract:

A method of charging a battery is provided that alters the amount of energy stored within the battery based upon a temperature profile across time. Battery materials and components, like liquid electrolyte or electrodes for instance, can be damaged when a rechargeable cell is exposed to elevated temperatures for extended amounts of time, thereby reducing the overall amount of energy that may be stored within the cell. This method monitors stored energy capacity and temperature. When a fully-charged cell is held at a temperature that exceeds a predetermined temperature threshold for an extended amount of time, the method discharges the cell, thereby reducing the amount of energy stored within the cell. For example, when a single, lithium-ion cell is maintained at 4. 2 V for over 10 hours, the method will discharge the cell by roughly 1% or 50 mV.

H04Q 7/22

US Classification:

4554121

Abstract:

A method, apparatus, and electronic device for optimizing a media presentation to a group. A memory may store a personal media user profile for a user.

International Classification:

H04L 9/32

US Classification:

705 51, 700 28

Abstract:

A method, apparatus, and electronic device for optimizing content acquisition are disclosed. A memory may store usage of a previous set of media content by the mobile device. An input/output device may receive a request for a current set of media content. A processor may create a user profile based on the usage and provides a first recommendation of a first digital rights agreement based on the user profile.

Appl. No.:

11/735623

Inventors:

JASON N. HOWARD - ALPHARETTA GA, US

Assignee:

MOTOROLA, INC. - LIBERTYVILLE IL

International Classification:

G08B 23/00

US Classification:

3406931

Abstract:

A method for communicating authenticity of a battery in a wireless communication device. The wireless communication device executes an authentication process to determine the authenticity of the battery used in the wireless communication device. The wireless communication device establishes a communication link with a wireless network. The wireless communication device notifies a network server if the battery is not authenticated while allowing the portable communication device to function. The network server performs a specific task in response to a notification received.

Bryan W. Fan - San Francisco CA, US

International Classification:

H01M 10/637

Abstract:

A battery system includes a plurality of battery cells connected in parallel. Each battery cell includes a positive and negative tab. The battery system also includes a plurality of thermal switch devices (e.g., temperature cut off (TCO) or positive temperature coefficient (PTC) devices). Each thermal switch device is electrically coupled to a respective cell. The battery system further includes a rigid-flex circuit board comprising a plurality of rigid regions. Each rigid region is physically and electrically connected to an adjacent rigid region by a respective flexible region. Each rigid region is electrically coupled to respective positive and negative tabs of a respective battery cell. Each thermal switch device prevents abnormal current flow (e.g., by limiting the flow of current at high temperatures) between a first battery cell that is coupled to the thermal switch device and a second battery cell that is adjacent to the first battery cell.

International Classification:

H02J 7/00

Abstract:

A method () and system () of adjusting a charging current to one or more cells () is provided. The method includes obtaining () a plurality of charging time periods, where each charging time period defined as a time period required to charge the one or more cells with a predefined current at one of a plurality of different temperatures. A temperature of the one or more cells is determined (). A predetermined current is scaled () by a quotient of a first charging time period defined by a first one of the plurality of different temperatures divided by a second charging time period defined by a second one of the plurality of different temperatures to obtain a magnitude of the charging current. The cells are charged () with the charging current at the magnitude to more rapidly charge the one or more cells at temperatures above room temperature.
