US Patent:

56006837, Feb 4, 1997
Filed:

May 1, 1995
Appl. No.:

8/432257
Inventors:

Kirk B. Bierach - Saratoga CA
Ximing Shi - Fremont CA
Assignee:

Motorola, Inc. - Schaumburg IL
International Classification:

H04L 700
US Classification:

375363
Abstract:

A new data format used in a communication system employing binary phase shift keying modulation and demodulation is described. The data format provides for a frame comprising a plurality of variable data bits and synchronization bits. The number of variable data bits in the data format of the present invention is more than the number of synchronization bits. The data format preferably includes a CRC field for error detection. In order to uniquely decode the information contained in the frame, the inverse of frame should not be a valid frame. A method for detecting invalid frames is also disclosed.

US Patent:

20220385089, Dec 1, 2022
Filed:

May 25, 2021
Appl. No.:

17/330185
Inventors:

- San Jose CA, US
Charles Henry Reynolds - Morgan Hill CA, US
Ximing Shi - Fremont CA, US
Assignee:

CyberSwitchingPatents, LLC - San Jose CA
International Classification:

H02J 7/00
Abstract:

A battery charger system includes multiple power channels to accommodate multiple battery chargers through a power input port. Each power channel includes a power outlet electrically coupled to the power input port through a relay. Each power channel further includes a current sensor. A controller is configured to estimate current in each of the power channels using the sensor signals, and configured to control the relays. The battery charger system is configured to provide power to the outlets by closing the corresponding relays, until the total current estimate is more than a maximum current limit, at which point the controller is configured to open the most recently closed relay. The controller is further configured to sequentially close remaining relays after the total current drops sufficiently, while maintaining the total current below the maximum current limit.
