Appl. No.:

10/634407

Inventors:

Justin Paul McNew - Santa Monica CA, US
Khaled I. Dessouky - Studio City CA, US
Jun Liu - Sherman Oaks CA, US

Assignee:

TechnoCom Corporation - Encino CA

International Classification:

H04Q 7/20

US Classification:

4554042, 4554561, 4554566, 455445, 455428

Abstract:

In one embodiment, the present invention is a method and system for calibrating a wireless network including a Mobile Switching Center (MSC), and a Position Determination Device (PDD). The wireless network is capable of determining the position of a handset. The method includes receiving a trigger from the MSC; sending a position request message to the PDD in response to the received trigger; receiving a position request response message from the PDD; continuously sending subsequent position request messages to the PDD in response to the same received trigger, until a termination command is received; terminating the sending subsequent position request messages, when the termination command is received; and generating output data including network calibration parameters.

International Classification:

H04W 4/00

US Classification:

370338, 370350, 455411, 4554141

Abstract:

A system and method for a novel broadcasting scheme (NBS) in a wireless local area network are described, which can operate with or without a network connection. The system permits transmission of application-specific data through a specific field in a beacon frame, the Service Set Identity (SSID). By implementing a NBS Processor in an AP and a NBS Parser in stations, the AP can broadcast application-specific data while the stations can automatically act upon the receipt of the broadcast.

Inventors:

Mark Johnson - Woodland Hills CA, US
Jun Liu - Burbank CA, US
Joseph Rice - Oakland CA, US

International Classification:

H04N 7/00
H04N 5/91

US Classification:

386096000

Abstract:

Selection of an audio-visual stream from among a plurality of streams occurs by first detecting a navigation packet within at least one stream that provides information concerning the stream, as well as those streams in lie in synchronism therewith. From the navigation packet, a determination is made which other streams lie in synchronism with the one stream, which audio and sub-picture data packets exist in each stream, and as well as which highlight information properties exist for selecting among the synchronized streams. At least one of the audio data packets, sub-picture data packets, or highlight information properties undergoes modification in accordance with information about at least one other synchronized stream to allow display of a viewer selectable button or the like to select among the synchronized streams and/or be presented with differing audio and/or sub-picture contents with each stream.

International Classification:

A61F 2/24

US Classification:

623 211

Abstract:

Certain embodiments of the present disclosure provide a prosthetic valve (e.g., prosthetic heart valve) and a valve delivery apparatus for delivery of the prosthetic valve to a native valve site via the human vasculature. The delivery apparatus is particularly suited for advancing a prosthetic heart valve through the aorta (i.e., in a retrograde approach) for replacing a diseased native aortic valve. The delivery apparatus in particular embodiments is configured to deploy a prosthetic valve from a delivery sheath in a precise and controlled manner at the target location within the body.

Assignee:

Edwards Lifesciences Corporation - Irvine CA

International Classification:

A61F 2/24
A61F 2/00

Abstract:

A prosthetic heart valve delivery system can include a catheter portion having a sheath that can cover and uncover the prosthetic heart valve mounted on an inner shaft, a handle having a sheath actuator operatively coupled to a proximal portion of the sheath, the inner shaft extending through the handle, and a shaft retractor releasably coupled to a proximal portion of the handle and fixedly coupled to a proximal portion of the inner shaft. A sheath actuator can move the sheath axially relative to the inner shaft when the shaft retractor is coupled to the handle, and a proximal movement of the sheath relative to the inner shaft can cause the sheath to uncover the prosthetic heart valve. The shaft retractor can be operable to retract the inner shaft and the nosecone proximally relative to the sheath when the shaft retractor is released from the handle.

International Classification:

A61F 2/24
A61F 2/00

Abstract:

A handle for a prosthetic heart valve delivery apparatus includes a housing, a motorized mechanism, and a holding mechanism. The housing is configured to be hand-held by a user and includes a distal opening. The motorized mechanism is disposed within the housing and is configured to be releasably coupled to a proximal end portion of a first shaft of the prosthetic heart valve delivery apparatus. When actuated, the motorized mechanism is configured to rotate the first shaft relative to the housing. The holding mechanism is disposed inside the housing and is configured to engage a proximal end portion of a second shaft of the prosthetic heart valve delivery apparatus such that the second shaft is axially and rotationally fixed relative to the housing, and the first shaft extends through the second shaft.
