Filed:

Appl. No.:

12/141439

Inventors:

Ramanuja Vedantham - Dallas TX, US
Sandeep Bhadra - Dallas TX, US

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H04W 4/00

US Classification:

370331, 455436

Abstract:

This invention employs an inherent tradeoff in a radio bearer dependent data handling method for intra-E-UTRA handoffs. For user equipment using real time data, the source node forwards to the target node not yet acknowledged real time service data units and disconnects. This makes the handoff latency short at the expense of data traffic between nodes. For user equipment not needing real time data, the source node continues to receive user equipment acknowledgements during a time out period and only forwards service data units acknowledged during the time out period. This reduces X2 interface traffic between the source and target nodes but extends the handoff latency.

F16B 47/00

Abstract:

The invention is a sticking type stand comprising; a frame an elastic supporting member having an elongated shape, and the longitudinal upper end of it being mounted on the frame the transverse section being curved with the central part being convex outwardly so that, if the external force is exerted on the convex front surface with the concave rear surface being supported, the longitudinal lower end of it can be elastically bent outwardly; and a sticking sheet provided on the rear surface of the frame

International Classification:

A61B 6/14

A61B 5/00
A61B 6/03

US Classification:

378 19

Abstract:

A dental cone beam computed tomography (CBCT) system, with a photon generator configured to emit x-ray photons; a photon detector spaced apart from the photon generator so as to accommodate at least a portion of a human mouth therebetween, the photon detector configured to receive the x-ray photons; and a processor in electronic communication with the photon detector. The photon detector is a direct-conversion detector configured to convert each received x-ray photon directly to a corresponding electrical signal, to determine information corresponding to a spatial pattern of the electrical signals, and to transmit the information to the processor. The processor is further configured to generate an image of the portion of the human mouth from the transmitted information.

International Classification:

A61B 6/00
A61B 6/14

US Classification:

378 62, 378147

Abstract:

An apparatus for positioning an X-ray imaging system. The apparatus includes an intraoral sensor sized and configured for placement within a human mouth, the intraoral sensor having one or more sensing elements for detecting X-rays, the intraoral sensor further having a signal generation element. Also included is a collimator unit having an X-ray collimator and first and second signal detection elements spaced apart from each other with the X-ray collimator positioned therebetween, the first and second signal detection elements spaced apart from each other, to thereby facilitate aligning of the collimator unit with the one or more sensing elements according to detection of signals from the signal generation element. Further included is an indicator unit located on the collimator unit, the indicator unit configured to display a determination as to whether the collimator unit is properly aligned with respect to the intraoral sensor.
