Filed:

Jul 28, 2011

Appl. No.:

13/136358

Inventors:

Philip J. Bruno - Oakland CA, US
Robert A.D. Schwartz - Oakland CA, US
Paul Schwartz - Oakland CA, US

International Classification:

H04L 9/32
G06F 3/02

US Classification:

726 16, 345168

Abstract:

A terminal for a computer system includes a keyboard incorporating modules for performing two factor authentication (TFA) for log-on of a user. TFA preferably combines a fingerprint scan with the proximity of a previously enrolled Bluetooth device that typically accompanies the user, such as a wireless phone or headset. The keyboard also includes an ultrasonic proximity detector aimed to detect the presence of the user at the keyboard and to terminate log-on when the user leaves the keyboard. The keyboard processor may be used as an encryption engine to encode all keystroke data and authentication/log-on transactions with the computer system.

International Classification:

A61B 1784

US Classification:

606 73

Abstract:

An osteosynthetic screw fastener and method of using such fastener is disclosed. When threaded onto an end of a bone screw for securing the screw to fractured bone, the fastener has a bone contacting surface that is alignable, independently of the orientation of the screw shaft, with an orientation of the bone surface adjacent to where the screw shaft exits the bone. The independent alignment of the fastener with the bone surface is due to a ball and socket configuration wherein the ball portion includes a spherical threaded nut and the socket is a cavity within the fastener for retaining the spherical nut. Accordingly, the fastener has an access to a threaded bore of the spherical nut so that the screw shaft can be threaded into the bore and secure the fastener against the bone. Additionally, the fastener's bone contacting surface is relatively large with projections thereon that secure the fastener in a desired orientation on the bone and thereby inhibit the fastener from shifting.

International Classification:

H04L 2736

US Classification:

332103

Abstract:

A modulating array transmitter employing a method that provides for improved power efficiency. The present inventors have observed that for symbols where pairs of power amplifiers of the modulating array transmitter are driven with opposing phases, the pairs of power amplifiers may both be keyed off to conserve prime power. The transmitter has a lookup table for providing a plurality of digital input signals and an on/off keying bit input signal, a plurality of quadraphase power elements that each comprise a modulator coupled to the lookup table and to a reference signal source, and a high efficiency amplifier coupled to a power source. A power combiner combines outputs of the plurality of power elements to produce a quadrature amplitude modulated (QAM) output constellation containing a plurality of symbols. The on/off keying bit input signal is used to key off selected pairs of power amplifiers that are driven with opposing phases and produce certain of the symbols of the constellation. When the selected pairs of power amplifiers are keyed off, prime power provided to the amplifiers of the transmitter is conserved.

International Classification:

F02G 1/055

Abstract:

A thermodynamic apparatus, such as a Stirling engine or a Vuilleumier heat pump, has a heat exchanger in which energy is exchanged between a working fluid and an exhaust gas stream. On top of the cylinder of the thermodynamic apparatus is a dome-shaped section. By incorporating the heat exchanger within the dome, the flow paths can be simplified, the number of separate components reduced, and overall weight reduced. Flow passages for the working fluid are embedded in the dome. Channels for the exhaust gases are formed in an outer surface. The passages and the channels are helically arranged, one clockwise and one counter clockwise. The dome can be cast with a core for the casting fabricated via three-dimensional printing. In some embodiments, the dome is made of fiber-reinforced material.

Abstract:

A computer keyboard is designed to accommodate a variety of security features that may be installed in the keyboard during manufacturing, whereby various combinations of devices that impart selected security features or other functions may be assembled. The keyboard assembly includes a base extension for accommodating the security devices, and a number of interchangeable modular tops supporting various discreet input technologies. This modular design is tooled to accommodate different combinations of technologies, such as biometric fingerprint readers, NFC-RFID receivers, auto locking sonar, game cartridges, and connector-supporting modules. Each interchangeable modular top can hold independent modular technology that can be used to construct an integrated device that meets the customer requirements without any substantial modification of the keyboard base or extension.
