view source
US Patent:

6789640, Sep 14, 2004
Filed:

Dec 3, 2002
Appl. No.:

10/308850
Inventors:

Richard W. Arling - Windham NH
W. Patrick Kelly - Goffstown NH
Philip LeMay - Bedford NH
John B. Morrell - Bedford NH
Jonathan B. Pompa - La Jolla CA
David W. Robinson - Manchester NH
Assignee:

DEKA Products Limited Partnership - Manchester NH
International Classification:

B60K 2814
US Classification:

180282, 180218, 318586
Abstract:

A device and method for providing yaw control for a balancing transporter that has two laterally disposed ground-contacting wheels. The method has the steps of receiving a user input of a desired yaw value; comparing an instantaneous yaw value with the desired yaw value to generate a yaw error value; processing the yaw error value to obtain a yaw command signal; and applying the yaw command signal in conjunction with a pitch command signal based on a pitch error in such a manner as to maintain balance of the transporter in the course of executing yaw control. The yaw command signal may include component terms quadratic in the pitch error and/or a function of a common wheel rotational velocity. A control input mechanism is wirelessly coupled to the controller of the balancing transporter so as to maintain the sealed integrity of a user interface.

Assignee:

DEKA Products Limited Partnership - Manchester NH
International Classification:

G05B009/03
B62D051/02
US Classification:

318139, 388903, 361 23, 180220
Abstract:

An electric device includes a motor and a motor drive for commanding a torque generated by the motor. A fault control circuit detects a fault condition associated with the motor drive. Upon detection of the fault condition, the fault control circuit adjusts the torque commanded by the motor drive.

Filed:

Oct 19, 2000
Appl. No.:

09/692268
Inventors:

Saligrama R. Venkatesh - Jersey City NJ, US
Alan M. Finn - Hebron CT, US
Philip LeMay - Bedford NH, US
Ronald Reich - Merrimac NH, US
Mark W. Davis - Vernon CT, US
James J. Dattolo - Manchester NH, US

Stephen J. Learman - Saline MI, US
Assignee:

Lear Corporation - Southfield MI
International Classification:

H04B 1/00
US Classification:

381 86
Abstract:

An improved user interface is installed in the cabin of a vehicle incorporating a cabin communication system using acoustic echo cancellation for improving the ease and flexibility of the cabin communication. Separate controls at each seat location enable the person occupying that seat to selectively converse with other occupants in the vehicle, create a recorded message and/or place a telephone call.

US Patent:

7740099, Jun 22, 2010
Filed:

Jul 9, 2007
Appl. No.:

11/774876
Inventors:

J. Douglas Field - Bedford NH, US
Jon M. Stevens - Manchester NH, US
Philip LeMay - Bedford NH, US
Michael T. Gansler - Candia NH, US
Assignee:

Segway Inc. - Bedford NH
International Classification:

B62D 49/08
US Classification:

180282
Abstract:

A transporter that includes a platform for supporting a load and at least one primary ground-contacting element. The transporter includes an actuator for applying torque to the at least one primary ground-contacting element for propelling the transporter with respect to a surface. The transporter also includes a controller for controlling the actuator, the controller includes an input for receiving specification by a user of a desired direction of travel based on a position of a member with respect to a fiducial axis, a differentiator for calculating a rate of change of the position of the member with respect to the fiducial axis, and a processor for generating a yaw command signal based at least on the position of the member and the rate of change of the position of the member which is weighted based on the level of experience of the user.
