Appl. No.:

09/698582

Inventors:

Keith V. Guinn - Basking Ridge NJ
Louis Thomas Manzione - Summit NJ
Ming-Ju Tsai - Livingston NJ
Hui Wu - Union NJ

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H01P 500

US Classification:

333116, 333 4, 333161

Abstract:

An electrical connecting element is disclosed comprised of a dielectric substrate having two conductor paths disposed on opposite sides and being substantially aligned with one another. The electrical connecting element employs differential-mode signaling such that the first conductor path carries a signal of opposite polarity to the second conductor path. A virtual ground exists between the differential + and - lines that permits an otherwise âgroundlessâ differential transmission line. The substantial alignment of the first and second conductor paths improves the space constraints, relative to conventional electrical connecting elements. The characteristic impedance of the disclosed differential transmission line depends on the width of the trace lines the thickness of the dielectric substrate.

Abstract:

An analog-to-digital (A/D) converter system converts an analog input signal into a digital output value by combining a plurality of digital sample values. For example, an A/D converter converts an RF analog signal into digital sample values. The A/D system comprises averaging circuitry which takes the average of N digital sample values from the A/D converter. The average is produced as the digital output value for digital processing circuitry. The signal to noise ratio (SNR) of the A/D system is thereby increased because in the averaging process noise components tend to cancel due to their random nature. The increase in the SNR provided by averaging the digital sample values enables the use of higher sampling rates because the processing gain achieved by averaging the digital signal samples counters the degradation caused by clock jitter. As such, a higher speed A/D converter can be used to directly convert an RF analog signal, thereby reducing the need for frequency conversion stages. In certain embodiments, the data rate or speed is reduced to produce digital output values at a data rate compatible with the digital processing circuitry.

Hui Wu - White Plains NY, US

International Classification:

G06F 3/01

Abstract:

A virtual reality (VR) system for VR desk application that allows a user to move in a VR environment while sitting in front of a working desk is provided. The VR system receives sensor data from a mobile device. The VR system generates a set of sitting motion data by interpreting the received sensor data as a motion of a limb of a person in a sitting posture. The VR system maps the set of sitting motion data into a set of movements in the VR environment. The VR system renders the VR environment and presents the rendered VR environment.
