Filed:

Sep 30, 2002

Appl. No.:

10/261548

Inventors:

Steven Jay Young - Los Gatos CA, US
Bich Quy Tran - San Jose CA, US

Assignee:

ARRIS Group, Inc. - Suwanee GA

International Classification:

H04N 7/173

US Classification:

725127, 725130

Abstract:

A system is described comprising: a local node to distribute multimedia content to a plurality of remote nodes; a power detection module to detect power usage of a multimedia device coupled to a first one of the remote nodes; a power analysis module to determine, based on the detected power usage, whether the multimedia device is in a first power state or a second power state; and a transmitter to transmit an indication of the detected state to the local node, the indication usable by the node to allocate multimedia processing resources across the plurality of remote nodes.

Filed:

Dec 22, 2005

Appl. No.:

11/316556

Inventors:

Bich Tran - San Jose CA, US

International Classification:

G08C 21/00

US Classification:

178018060

Abstract:

One embodiment in accordance with the invention includes a capacitive sensing apparatus that includes a capacitive sensor configured to sense an object proximate to a physical capacitive sensing reference surface. The capacitive sensing apparatus also includes a plurality of dielectric materials disposed between the capacitive sensor and the physical capacitive sensing reference surface. Note that at least one of the plurality of dielectric materials has a non-uniform thickness. The plurality of dielectric materials can be configured such that capacitive coupling between the capacitive sensor and the object proximate to the physical capacitive sensing reference surface is substantially constant across the physical capacitive sensing reference surface.

Appl. No.:

16/894040

Inventors:

Bich Q. Tran - Saratoga CA, US

International Classification:

A62B 23/06

Abstract:

A personal protection device includes one or two elongate members for engaging into the nostrils of the nose of a user. The elongate members each includes gridded ports for allowing air to pass through the elongate member when breathing in and for allowing air to exit via the elongate member when breathing out. Sensors are placed in the air flow pathway to detect pathogen presence, and the primary air filter is positioned in the elongate member. In yet other embodiments, a disposable version is disclosed. The eyewear can also be used as part of an extended reality system, and when game playing, particularized scents can be rendered to the nose to enhance the gaming experience. In another aspect, systems and methods protect against pathogen by sampling an environment of a travel path with a plurality of pathogen detectors along the travel path to detect a presence of one or more pathogens, wherein at least one detector includes a nano-sensor with receptacles to bind to the pathogens and wherein the nano-sensor changes resistivity, inductance or capacitance upon pathogen binding; directing air towards said pathogen detectors; contact tracing a user mobile device having a mobile identification (ID) carried by each user, wherein the mobile device comprises a memory storing mobile IDs of all devices within a predetermined radius of the user mobile device; and performing deep learning with a neural network receiving data from the pathogen detectors and to the user mobile device to detect a presence of one or more pathogens.
