US Patent:

20100032911, Feb 11, 2010

Filed:

Aug 7, 2009

Appl. No.:

12/537327

Inventors:

Joseph Sarokhan - Basking Ridge NJ, US
Steven Kamara - Princeton NJ, US
Michael Yang - Princeton NJ, US

Assignee:

SterraClimb LLC - Princeton NJ

International Classification:

B62B 9/02
B62B 5/02

US Classification:

280 528

Abstract:

A wheeled vehicle comprising a power-driven spider assembly for ascending and descending stairs. The vehicle includes an angular position sensor providing input to a controller operable to control a servo-motor to effectively lock the position of the spider relative to the frame, regardless of the hand truck's spatial orientation relative to a vertical plane, or any balancing of the hand truck. The angular position sensor provides input to the controller, which is programmed with predefined angular zones of instability, and causes the controller to accelerate rotation of the spiders through those zones when the wheeled vehicle is in the descent mode, to avoid instability of the hand truck. A hand truck may include a removable basket and/or a pivotable platform usable to transport loads.

US Classification:

701 22, 180 71

Abstract:

An apparatus and method for supplying operating voltages to a plurality of electronic devices is disclosed. A plurality of power supply modules of a modular power supply may output voltages to at least two electronic devices respectively. The apparatus may identify a failure of one of the power supply modules. The electronic device may be disconnected from the failed power supply module, and then reconnected to a functional power supply module of the modular power supply. switching a supplied voltage of the functional power supply module of the modular power supply, wherein the supplied voltage matches the set output voltage of the failed power supply module. If necessary, a supplied voltage of a functional power supply module may be switched to match the set output voltage of the failed power supply module.

Abstract:

In a system and method for auditing transactions where a set of image based transactions are received over a communications network, and stored in a central data store, the set of image based transactions are associated with a unique identifier associated with a user. A transaction format is identified from the set of image based transactions, utilizing a processor to apply a preprocessing to the set of image based transaction based on the identifying. The preprocessed image based transactions are processed into a series of text based transactions, wherein each image based transaction has a related text based transactions and each text based transaction has a plurality of data representing the transaction. The plurality of data for each text based transaction is stored and a quality identifier is associated with each text based transaction. An identifier is applied to a text based transaction based on the quality identifier.
