US Patent:

7876268, Jan 25, 2011

Filed:

Sep 4, 2007

Appl. No.:

12/438033

Inventors:

James P. Jacobs - Littleton MA, US

International Classification:

G01S 3/02

US Classification:

342465

Abstract:

Various aspects of the present invention are shown and described, each of which has stand alone utility in a navigated medical environment. A receiver position calibration system and method facilitates calibration of a reference frame prior to each navigated procedure. A concept and application of confidence weights is introduced. Confidence weights can be applied to distance calculations to mitigate the effects of interference and increase the tolerance of the navigated medical system. Multi-path interference is minimized through the transmission of a signal having a pattern of unique frequencies and filtering of the distance calculations for each frequency to identify the ‘best’ distance in the presence of multi-path interference. A position determination method and system that transmits a signal having multiple frequency components permits positions to be identified with high resolution over a large area.

Appl. No.:

13/662744

Inventors:

Raytheon Company - Waltham MA, US
James L. Jacobs - Fort Wayne IN, US

Assignee:

RAYTHEON COMPANY - Waltham MA

International Classification:

G06F 21/00

US Classification:

726 3

Abstract:

A system to establish a trustworthiness of an autonomous agent is provided. The system includes a plurality of computing devices disposed in signal communication with one another via a network, at least one of the plurality of the computing devices being configured to serve as a host server for an autonomous agent trustworthiness establishing (AATE) application. The AATE application is configured to define a micro-theory of trust elements, apply trust building patterns to the autonomous agent, provide a visualization of autonomous agent skill claims and constraints via the network and provide a recommendation tracking system for sharing and tracking a reputation of the autonomous agent during testing and deployment via the network.

Filed:

May 6, 2015

Appl. No.:

14/705639

Inventors:

James Sumner Jacobs - Sharon MA, US

International Classification:

A61H 3/04

Abstract:

Described is a walker that is a front entry walker that surrounds the user with a frame on three sides and that includes a fold-down seat when needed. The frame includes a first side frame, a second side frame and a rear frame connected between the first and second side frames. The rear frame includes the seat such that when the seat is in the stowed position, the seat in conjunction with the first and second side frames collectively surround the user on at least three sides. Further, an adjustable arm rest is attached with each of the first and second side frames. Notably, each adjustable arm rest has a forearm support and corresponding brake system.
