Appl. No.:

10/794331

Inventors:

Jason P. Luck - Arvada CO, US

Assignee:

Sandia Corporation - Albuquerque NM

International Classification:

G06T 17/10

G06K 9/64

US Classification:

382103, 382154

Abstract:

A markerless method is described for tracking the motion of subjects in a three dimensional environment using a model based on linked kinematic chains. The invention is suitable for tracking robotic, animal or human subjects in real-time using a single computer with inexpensive video equipment, and does not require the use of markers or specialized clothing. A simple model of rigid linked segments is constructed of the subject and tracked using three dimensional volumetric data collected by a multiple camera video imaging system. A physics based method is then used to compute forces to align the model with subsequent volumetric data sets in real-time. The method is able to handle occlusion of segments and accommodates joint limits, velocity constraints, and collision constraints and provides for error recovery. The method further provides for elimination of singularities in Jacobian based calculations, which has been problematic in alternative methods.

International Classification:

F25D 31/00
F25D 23/10
F25B 21/02

Abstract:

The in-wall chiller may include a housing having a size and shape, including a depth of approximately 3.5 inches and a width of approximately 14.5 inches, conductive for installation in a standard size wall frame. The in-wall chiller may further include one or more cooling modules disposed in the housing, which may include a chilling plate coupled to one side of a Peltier chip and a heat sink coupled to the other side, wherein the relatively low temperature transferred to the chilling plate cools water within the in-wall chiller, which may be stored for an extended duration within an insulated storage tank; the heat extracted from the cooled water being transferred to the heat sink and dissipated out from the in-wall chiller by a fan mounted thereon.

Daniel Small - Reno NV, US

International Classification:

G08B 21/18
A61H 35/02
A47K 3/28

Abstract:

The water detection sensor includes a retrofit system such as a water-proof housing that selectively attaches to an exterior of a water conduit coupled at or near a dispense outlet of an emergency safety shower or emergency eyewash unit. The sensor may include a pair of guidewires that extend through the body of the water conduit and have a pair of respective electrodes that reside therein in non-conductive relation during an “off” or “no flow” condition. In an “on” or “flow” condition, the electrodes become immersed in water and can conduct electricity therebetween by way of the electrically conductive water medium. As such, a water conductivity circuit coupled thereto and disposed within the water-proof housing may relay a signal to a controller, which activates an audible or visual alarm that water is flowing through the emergency safety shower and/or the emergency eyewash unit.

Inventors:

- Sparks NV, US
Daniel Small - Reno NV, US

International Classification:

A47K 3/28
A61H 33/00
G05D 23/13

Abstract:

An emergency shower includes a column having upper and lower inlets, outer, intermediate, and inner pipes defining outer, intermediate, and inner conduits, and one or more heating coils positioned within one or more of the conduits. An instantaneous water heater can be integrated into the column of the emergency shower. The emergency shower can include a shower head and an eyewash assembly for cleaning a person after the person encounters toxic materials.

Abstract:

The shower head nozzle as disclosed herein includes a quick-connect coupling for selectively attaching the nozzle to a downwardly extending conduit or tube for directing tested water through a test unit and into a bucket or drain, wherein the test unit may include a flow meter for measuring real-time water flow rate and a temperature sensor for measuring real-time water temperature dispensed from the shower head, thereby reducing the testing time, more accurately determining flow-rate and water temperature, and decreasing the amount of waste water.
