Filed:

Apr 26, 2010

Appl. No.:

12/767669

Inventors:

Shawn P. STAPLETON - Burnaby, CA
Albert S. LEE - San Mateo CA, US

Assignee:

DALI SYSTEMS CO. LTD. - George Town Grand Cayman

International Classification:

H04L 12/26

US Classification:

370242

Abstract:

A system and method for remotely monitoring, communicating with, and reconfiguring power amplifier systems. A communications link is provided in field-deployed PA systems, for enabling remote communication with appropriate digital components such as microprocessors or other communications-capable portions of the power amplifier systems. The communications link permits operating parameters of the PA to be monitored and sent back to a remote terminal such as a web server or other computer mainframes via any suitable wired or wireless connection including internet, Ethernet, wireless, WiFi, WiMAX, cellular, local area networks (LAN), wide area networks (WAN), Bluetooth, and so forth. The communication is bi-directional, so that the remote host can download to the PA updates, cMobile operators and/or other service providers can reduce significant operating and capital expenses related to their radio networks maintenance and PA replacement by practicing this invention.

International Classification:

H01L 21/321

US Classification:

438682

Abstract:

Methods are provided for processing a substrate for depositing an adhesion layer between a conductive material and a dielectric layer. In one aspect, the invention provides a method for processing a substrate including positioning a substrate having a conductive material disposed thereon, introducing a reducing compound or a silicon based compound, exposing the conductive material to the reducing compound or the silicon based compound, and depositing a silicon carbide layer without breaking vacuum.

Abstract:

The present disclosure is a novel utility of a software defined radio (SDR) based Distributed Antenna System (DAS) that is field reconfigurable and support multi-modulation schemes (modulation-independent), multi-carriers, multi-frequency bands and multi-channels. The present disclosure enables a high degree of flexibility to manage, control, enhance, facilitate the usage and performance of a distributed wireless network such as flexible simulcast, automatic traffic load-balancing, network and radio resource optimization, network calibration, autonomous/assisted commissioning, carrier pooling, automatic frequency selection, frequency carrier placement, traffic monitoring, traffic tagging, pilot beacon, etc.

G02B 7/02
G06K 19/07
G06K 7/10

Abstract:

A headset for experiencing an augmented and/or a virtual reality environment may include a housing defining an interior cavity, with optical components received in the interior cavity of the housing. A front face may be rotatably coupled to a front portion of the housing to selectively enclose the interior of the housing. A computing device including a display may be received in a slot defined between the front portion of the housing and the front face. A face pad may be removably coupled to the housing, opposite the front face, so as to enclose the optical components in the housing. A user may view an augmented/virtual reality environment displayed on the display through the optical components received in the housing. An adjustable head strap assembly may adjustably position the headset on the head of the user.
