John Spence - Washington NC, US

International Classification:

H04L012/66

US Classification:

370/352000, 370/356000

Abstract:

A method and system for assigning multiple wired and/or wireless internet communication channels in a local loop system that utilizes unique network, multi-protocol routing, and multiple forms of internet access and distribution. The system is designed to support POTS (Plain Old Telephone), ISDN, T-1, DS-3, and spread and direct spectrum wireless transmission and reception. The system is inherently flexible so as to provide Enhanced Bandwidth and quality of service (QOS). The system further utilizes scaleable architecture for bandwidth expansion and higher data rate services. It also utilizes optional grounding schemes for lightning and high-potential static energy abatement.

B05B 7/00

US Classification:

239 11, 239398

Abstract:

A nozzle for producing a single-file stream of droplets of a fluid, methods using the nozzle, and an injector, comprising the nozzle of the invention, for providing the single-file stream of droplets of a fluid to a high-vacuum system are described. The nozzle comprises two concentric tubes wherein the outer tube comprises a smoothly converging-diverging exit channel and the outlet end of the first tube is positioned within the converging section of the exit channel.

Assignee:

Rockwell International Corporation - Newport Beach CA

International Classification:

G11C 706
G01R 1900

US Classification:

327 57

Abstract:

A high speed current sense amplifier useful in memory devices, which includes a current-to-voltage amplifier that is coupled to a voltage amplifier. The current-to-voltage amplifier has an input impedance that is lower than its output impedance. The voltage amplifier has an input impedance that is larger than the input impedance of the current-to-voltage amplifier. The current sense amplifier can sense the current relationship between two current inputs in about 200 pico-seconds. Embodiments of the current sense amplifier enable current sensing either near the power supply voltage or near ground, thus eliminating the need for intermediate voltages. Embodiments of the current sense amplifier draw current from the current inputs only during the 200 pico-second sensing time and does not require external latching circuitry.
