Appl. No.:

10/032089

Inventors:

Chien-Hsun Huang - Tu-Chen, TW
Chih-Hsien Chou - San Jose CA
Chung Ta Cheng - Santa Clara CA

Assignee:

Hon Hai Precision Ind. Co., Ltd. - Taipei Hsien

International Classification:

H01Q 138

US Classification:

343700MS, 343702

Abstract:

An antenna ( ) includes a first radiating branch ( ), a second radiating branch ( ), a grounding plate ( ), a linking segment ( ), a connecting plate ( ), and a feed cable ( ). The first radiating branch is in a first plane and is provided to receive/transmit signals in a first frequency band. A feed point ( ) is formed on the first radiating branch. The second radiating branch is in a second plane perpendicular to the first plane and is provided to receive/transmit signals in a second frequency band. The grounding plate is in a third plane facing the first plane for fixing and grounding the antenna. The feed cable includes a core conductor ( ) and an outer shield conductor ( ). The core conductor is electrically connected to the feed point for feeding signals into the antenna. The outer shield conductor is soldered to the grounding plate.

Appl. No.:

11/487286

Inventors:

Chung Lung Cheng - La Verne CA, US

International Classification:

B65D 6/28

US Classification:

220 422

Abstract:

A case, such as a suitcase or a photo case, for holding an object at an exterior thereof includes a case body and a hinge edge frame arrangement. The hinge edge frame arrangement includes a first edge frame, a second edge frame and a resilient element. The first edge frame is extended along the utility edge of the case body to retain a utility panel in position, wherein the first edge frame has an elongated holding slot formed between an outer and an inner wall along a utility edge. The second edge frame includes an elongated pivot arm, having an enlarged end portion, pivotally received in and extended along the holding slot of the first edge frame, and a clipping member extended from the pivot arm, wherein the clipping member is adapted to fold between a clipping position and a releasing position for detachably clipping an object by the clipping member.

Appl. No.:

8/076824

Inventors:

Martin A. Katz - Menlo Park CA
Chung H. Cheng - San Jose CA
Sergio Nacht - Los Altos CA

Assignee:

Advanced Polymer Systems, Inc. - Redwood City CA

International Classification:

A61K 916

US Classification:

424501

Abstract:

Benzoyl peroxide intended for topical application is incorporated in novel formulations in which it is retained as impregnants inside the pores of porous solid particles or microspheres. The pores form a continuous network open to the exterior of the particles, permitting outward diffusion of the benzoyl peroxide impregnant at a controlled rate depending on the pore size. The impregnated particles are prepared by impregnation of preformed particles with the benzoyl peroxide.

Abstract:

Retinoic acid compositions intended for topical application are incorporated in novel formulations in which they are retained as impregnants inside the pores of porous solid particles or microspheres. The pores form a continuous network open to the exterior of the particles, permitting outward diffusion of the retinoic acid impregnant at a controlled rate depending on the pore size. The impregnated particles are prepared by impregnation of preformed particles with the retinoic acid.
