US Patent:

41615573, Jul 17, 1979

Filed:

Mar 23, 1978

Appl. No.:

5/889285

Inventors:

Fred K. Suzuki - Arlington Heights IL
Thomas W. Davison - Streamwood IL

Assignee:

Liquid Crystal Products, Inc. - Arlington Heights IL

International Classification:

B44F 100

US Classification:

428 1

Abstract:

An alkyd-type polymeric plasticizing resin or castor oil is incorporated in a mixture of a polyvinyl butyral film-forming polymer and a cholesteric liquid crystalline phase material, to provide a composition which when in the form of a film exhibits accentuated intensity and contrast of visible light waves reflected by the material.

Appl. No.:

5/658407

Inventors:

Fred K. Suzuki - Arlington Heights IL
Thomas W. Davison - Streamwood IL

Assignee:

Liquid Crystal Products, Inc. - Arlington Heights IL

International Classification:

A61B 1000

US Classification:

128 2R

Abstract:

A composition of matter having thermal color responsive characteristics and adapted for exhibiting improved color contrast includes an enantiotropic cholesteric liquid crystalline phase material, and at least two oil-soluble dyes dissolved in the material in a total dye concentration of 0. 01-1% by weight of the composition, each of the dyes reflecting light of a different wave length in the range of 400 to 700 nanometers, and said dyes together absorbing light of substantially all wave lengths within said range. A method of effecting venapuncture in the human body includes the steps of cooling the skin over a venous area, applying directly on the skin a layer of the composition about 100 to 300 microns thick, allowing the skin over the venous area to rewarm due to venous blood flow, until the said material exhibits a mesophase color change to thereby delineate a vein therebeneath, and directing an instrument for venapuncture to a site in the said area indicated by the delineation to constitute the location of a vein.

Assignee:

Liquid Crystal Products, Inc. - Arlington Heights IL

International Classification:

A61B 1000

US Classification:

128736

Abstract:

A method of effecting venipuncture in the human body includes the steps of cooling the skin over a venous area of the body by applying a cold pack thereto and providing on the cooled skin in heat exchange relation thereto a layer of an enantiotropic cholesteric liquid crystalline phase material exhibiting a mesophase color change at a temperature reached by the skin due to venous blood flow, warming the cooled skin by venous blood flow in such area thereby to produce a mesophase color change in the material delineating a vein therebeneath, and directing an instrument for venipuncture to a site in such area indicated by the delineation to constitute the location of a vein.

International Classification:

G06F 3/033

Abstract:

Various devices for providing foot controlled computing device inputs are discussed herein. Some embodiments may include a rolling foot controller including a housing, one or more motion sensors disposed within the housing, and processing circuitry. The housing may include an upper portion configured to interface with one or more feet, and a lower portion configured to facilitate motion of the rolling foot controller when disposed on a ground surface. The processing circuitry may be configured to receive the motion data generated by the one or more motion sensors, and provide the motion data to a computing device, especially with regards to rotation in the pitch, yaw, and roll directions. The upper portion is generally of convex shape, curved about one or more axes, and the lower portion is generally convex as well, curved about two or more axes.
