Joon T. Choi - Los Angeles CA 90006

International Classification:

A47G 2110

US Classification:

294 992, 294 11

Abstract:

A chopstick manipulator comprises a bridge and clamps. Each clamp includes an inner support having an inner surface where an upper half of the inner surface has a mid portion so the bridge interconnects each mid portion thereof, a rear support extending from a rear end of the inner support so that about a right angle is formed by each outer surface of the inner and rear supports, and a distal support extending substantially forward from an outer end of the rear support while forming a substantially prismatic shape. The distal support is defined by an outer surface, a rearward slant surface and a forward slant surface so that a prismatic ridge by the respective slant surfaces approaches the outer surface of the inner support where an angle by the rear support and the rearward slant surface is less than 90 degrees.

Abstract:

Self-asserted socio-demographic attributes of individuals' identities are verified using social network analysis and other means. Through these processes, parties to a transaction or interaction arc provided a measure of confidence about another party's self-asserted socio-demographic attributes, such as age, gender, marital status, etc., in order to assist in determining whether or not to pursue the transaction or interaction. The measure of confidence may be provided as a quantitative “score” indicative of the likelihood the user's self-asserted attribute is actually true. The quantitative score is derived by analyzing a web of trust in which the user is embedded.

Appl. No.:

12/400181

Inventors:

Joon T. Choi - Los Angeles CA, US

International Classification:

B05B 11/00
B67D 5/40

US Classification:

222382, 2224644

Abstract:

An aspect of the invention provides a spray device for siphoning fluid. The spray device comprises a container, a pump, and a siphon tube. The container has an opening at a top portion. The pump is provided on the opening of the container. The siphon tube extends from the pump down to a bottom portion of the container, and the siphon tube comprises a flexible portion in a middle portion of the siphon tube for allowing a lower end portion to fall downward under gravity when the spray device is tilted from a vertical position. The lower portion of the siphon tube is configured to reach center or corners of the bottom portion of the container. The flexible portion of the siphon tube may be disposed in the middle portion of the siphon tube such that the lower portion below the flexible portion falls downward due to weight of the lower portion due to gravity.
