US Patent:

7898155, Mar 1, 2011

Filed:

Oct 16, 2008

Appl. No.:

12/252520

Inventors:

Kimberly Peacock - Fresh Meadows NY, US

International Classification:

H01L 41/107
H02N 2/18

US Classification:

310339, 290 1 R

Abstract:

A system for generating electrical power supply signals includes at least one heat engine having a chamber that undergoes heating/cooling cycle and corresponding pressure variations. At least one piezoelectric transducer is deformed in response to the pressure variations of the heat engine. A power converter transforms the electric signals generated in response to deformation of the piezoelectric transducer(s) to a desired electrical power supply signal. The heat engine preferably uses a geothermal source of cold and an ambient source of hot or vice-versa. Hydrogen can be used as a working fluid, and metal hydride material can be used for absorbing and desorbing hydrogen during the cycle of heating and cooling of the heat engine. A phase change material can also be used. The power converter preferably includes an electromechanical battery with a flywheel storing rotational energy and possibly an electrostatic motor that adds rotational energy to the flywheel.

Appl. No.:

11/867038

Inventors:

Kimberly Peacock - Fresh Meadows NY, US

International Classification:

H02N 2/18

US Classification:

310322, 310339, 310341, 381173, 290 1 R, 290 1 A, 290 2

Abstract:

A system for generating electrical power supply signals includes at least one heat engine that undergoes heating/cooling cycles and corresponding temperature variations. A thermoacoustic element is thermally coupled to the chamber. The temperature variations of the heat engine induce thermoacoustic oscillations of the thermoacoustic element which form a pressure wave. At least one piezoelectric transducer is deformed by the pressure wave. A power converter can be used to transform the electric signals generated in response to deformation of the at least one piezoelectric transducer to a desired electrical power supply signal. The heat engine preferably uses a geothermal source of cold and an ambient source of hot (typically used in the summer months), or vice-versa (typically used in the winter months).

Filed:

Jan 14, 2003

Appl. No.:

10/220221

Inventors:

Kimberly Peacock - Fresh Meadows NY, US

International Classification:

G06F015/173

US Classification:

709/224000

Abstract:

Methods and apparatus for controlling traffic in a communications network (FIG. ) include providing a plurality of local active nodes and a master node wherein the local active nodes poll network equipment associated with them and transmit information about network utilization to the master active node. Periodically the master active node transmits network status information to the local active nodes. The local active nodes may also query the master active node about network status. Hosts coupled to a local active node query the node for network status.
