Appl. No.:

09/983423

Inventors:

Dilip A. Amin - San Jose CA
Chang Hong Wu - Cupertino CA

Assignee:

Juniper Networks, Inc. - Sunnyvale CA

International Classification:

H03L 700

US Classification:

327143

Abstract:

A voltage sequencing circuit powers-up electrical systems by sequentially enabling a series of power supply lines to the electrical system. After each power supply line is enabled, the voltage sequencing circuit waits a pre-programmed delay time before enabling the next power supply line. The delay time allows the newly enabled power supply line to settle. Additionally, the voltage sequencing circuit constantly monitors previously enabled power supply lines while continuing to enable the remaining power supply lines. If any of the previously enabled lines fail, the voltage sequencing circuit disables the power supply line before reinitiating a complete power-up sequence.

International Classification:

G09B019/00

US Classification:

434257000

Abstract:

A stance guide and method of use are disclosed to help a user achieve and hold a number of stances hence providing corresponding health benefits to the user. The stance guide includes an adjustable foot engaging and an adjustable body engaging device, connected to each other with a frame, for guiding and engaging the user's feet and body while accommodating a range of user population. The foot engaging or the body engaging device can include a sensing and signaling device plus a timer to help the user achieve correct stances for a desired time duration. A display device can be included for displaying the stance images as a visual aid. A guard device can be included for reducing the risk of an accidental fall during practice. Specific designs of the stance guide are presented with health benefits of reducing excess urination, enhancing sleep quality and reducing body weight.

Abstract:

An on-genital erection device for inducing and maintaining the human sexuality are proposed. The on-genital erection device includes an essentially cylindrical elastomeric sleeve surrounding the pre-erection penis. The elastomeric sleeve includes self-sealing air-ports for engaging with an air pump thus forming an expandable and suctioning air tight enclosure of the penis causing its erection. The elastomeric wall can be made of a laminate of at least two layers L, i=1, 2, . . . , M. Each Lincludes a surface relief pattern forming a surface relief pattern set that in turn defines a plurality of air paths PTwherein at least one air path PTis communicatively connected with the penis surface. Thus, after the plurality of air paths PTget engaged through their respective air-ports with an external multi-port air pumping device, the desired expandable and suctioning enclosure is formed.
