US Patent:

6369737, Apr 9, 2002

Filed:

Oct 30, 1997

Appl. No.:

08/960823

Inventors:

David Yang - Palo Alto CA
Abbas El Gamal - P. A. CA
Boyd Fowler - Sunnyvale CA

Assignee:

The Board of Trustees of the Leland Stanford Junior University - Palo Alto CA

International Classification:

H03M 112

US Classification:

341155, 341169

Abstract:

An analog-to-digital conversion scheme allows the conversion of a small dynamic range analog signal into a floating-point, digital representation with a larger dynamic range. A montonically changing analog signal is reset to a reference value at time t=0. The analog signal is then sub-converted by an analog-to-digital converter with maximum input signal level S to corresponding digital representations at several sub-conversion times t=T T t=T T ,. . . t=T T , where T T. These digital representations are then suitably combined to produce a cumulative, floating-point digital representation which accurately represents the analog signal even if the analog signal has a value greater than S at time t=T.

International Classification:

A01N 4302

US Classification:

514449

Abstract:

Disclosed are water soluble compositions of paclitaxel and docetaxel formed by conjugating the paclitaxel or docetaxel to a water soluble polymer such as poly-glutamic acid, poly-aspartic acid or poly-lysine. Also disclosed are methods of using the compositions for treatment of tumors, auto-immune disorders such as rheumatoid arthritis. Other embodiments include the coating of implantable stents for prevention of restenosis.

US Classification:

345 82, 345 39, 34082582, 359149, 359181

Abstract:

A dot matrix display system made up of light emitting diodes (LEDs), n which one or more LEDs are modulated and encoded with audio information or messages is disclosed. The system has a LED dot matrix display panel with an interface circuit to a computer, an audio signal transmitter, and a receiver. An executive program runs on the computer for the visual display control of characters, decorative pattern or messages on the display panel. The receiver combined with a speaker is located at a distance from the display panel. The receiver is designed to demodulate the optically transmitted audio information and broadcast the messages with the speaker. The modulation of the LEDs includes a voltage-controlled oscillator (VCO) for varying the frequency of on/off periods of said light emitting diodes. The frequency is high enough such that the perceivable light appears to be constantly illuminated to the human eye.

US Classification:

229167, 22912234, 229141, 229178

Abstract:

The present invention is directed to a folder type file tray assembled from a single paperboard blank. The file tray can be flattened to a reduced size during storage or transportation. It can also be assembled into different forms for different usage. The first form of file tray is an open-top box with a front opening for usage as a conventional file tray. The second form of file tray is an open-top box without a front opening, i. e. , surrounded by four side walls for usage as a desk-top tool box. The third form of file tray is an open-top box with a foldable closing lid for usage such as a storage box. Additionally, the file tray of present invention can be stacked up directly to each other in multiple numbers without additional means of support. The file tray of present invention has low material and manufacturing costs. If needed, one side of paper blank can be laminated with higher quality paper or decorative material to enhance the appearance of file tray of present invention.
