US Patent:
6400482, Jun 4, 2002
Filed:
Apr 14, 1999
Appl. No.:
09/291709
Inventors:
Elmer C. Lupton - Charlestown MA
Steven B. Leeb - Belmont MA
George B. Hovorka - Rockport MA
Deron Jackson - San Jose CA
Billie L. Bentzen - Berlin MA
Assignee:
Talking Lights, LLC - Boston MA
International Classification:
H04B 1010
US Classification:
359154, 359142, 359144
Abstract:
A communications network comprised of a source of information to be transmitted in the form of a signal, one or more transmitters which emit light suitable for illumination and including means for modulating the light with the information signal, a medium such as a fluid through which the light passes, and one or more receivers for receiving the light and demodulating the signal to obtain the information. A user for the information may be a device, such as a computer or a compact disk player, or it may be a person, perhaps with some form of sensory or mental impairment. The information may be encrypted, may provide directional guidance, such as to a user moving in a vehicle, and/or may be transmitted simultaneously over multiple channels. Various types of visible light assemblies may be employed, with varying power inputs and outputs.

Non-Flickering Illumination Based Communication

US Patent:
2003003, Feb 13, 2003
Filed:
Jul 23, 2002
Appl. No.:
10/201378
Inventors:
Steven Leeb - Belmont MA,
Deron Jackson - San Jose CA,
Elmer Lupton - Charlestown MA,
George Hovorka - Melrose MA,
International Classification:
H05B037/02
US Classification:
315/291000, 315/360000, 315/362000
Abstract:
A system for and method of generating electromagnetic radiation in which the radiation has both a first and second utility. The electromagnetic radiation is modulated to produce electronically detectable variations to achieve the second utility, the variations not affecting the first utility. In one embodiment, the electromagnetic radiation is visible light. In this embodiment, the first utility is illumination and the second utility is the transmission of data. In another embodiment, the invention provides a lamp for generating visible light capable of providing illumination and transmitting data to a receiver. Any variations in the visible light resulting from the data transmission are imperceptible by a human eye regardless of the nature of the data being transmitted. In yet another embodiment, a power line carrier modem may be used with the present invention to transmit information to the source.

A Dc Power Supply Controller

View page
US Patent:
5656923, Aug 12, 1997
Filed:
Apr 10, 1995
Appl. No.:
8/419271
Inventors:
Aaron M. Schultz - Cambridge MA
Steven B. Leeb - Belmont MA
Ahmed Mitwalli - Cambridge MA
George C. Varghese - Newton MA
Assignee:
The Whitaker Corporation - Wilmington DE
International Classification:
G05F 170
H02J 700
US Classification:
323207
Abstract:
A large signal, linear, digital, unity power-factor controller for controlling a power supply is disclosed. The power supply controller includes a voltage controller and a current controller. The voltage controller is a feed forward and proportional-integral type of controller. By determining the control command of the voltage controller as a function of the feed forward load power, the power term in the state equations for the voltage controller is eliminated. As such, the current controller operates in time domain in such a way that the voltage controller appears as a unit time delay to the current controller. The load is a battery incorporated within an electrically-powered vehicle. The controller operates to charge the battery. The connection between the battery and the power supply being controlled is an inductive coupling.

Multiprocessing Transient Event Detector For Use In A Nonintrusive Electrical Load Monitoring System

View page
US Patent:
5717325, Feb 10, 1998
Filed:
Jan 5, 1996
Appl. No.:
8/583584
Inventors:
Steven B. Leeb - Belmont MA
Umair A. Khan - Santa Clara CA
Steven R. Shaw - Cambridge MA
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
G01R 1906
US Classification:
324 7612
Abstract:
A multi-processing transient event detector for use in a nonintrusive electrical load monitoring system has been provided. Templates of transient pattern data associated with each electrical load which may be monitored are stored. Such templates are then used to match and correlate with the actual monitored transient pattern data at the load site. The decomposition in which time scales are changed is accomplished in parallel along with one or more parallel event detection processing modules for each decomposition.

US Patent:
2012022, Sep 6, 2012
Filed:
Mar 3, 2011
Appl. No.:
13/039382
Inventors:
John J. Cooley - Cambridge MA,
Steven B. Leeb - Belmont MA,
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
H02J 1/00
H03K 3/00
G05F 3/16
US Classification:
307 82, 323311, 327109
Abstract:
Switched capacitor multilevel output DC-DC converters can be used as panel integrated modules in a solar maximum power point tracking system. The system can also include a central input current-controlled ripple port inverter. The system can implement per panel MPPT without inter-panel communication, electrolytic capacitors or per panel magnetics. A Marx converter implementation of the switched capacitor module is studied. Average total efficiencies (trackingĂ—conversion) greater than 93% can be achieved for a simulated 510 W, 3 panel, DC-DC system.
