Abstract:
Transferring data in a network is disclosed. Transferring includes receiving a Provider Backbone Transport (PBT) frame, identifying a plurality of location specific identifiers in the PBT frame, mapping the PBT frame to a service based at least in part on the plurality of location specific identifiers, formatting the PBT frame according to the service to obtain a service frame, and transferring the service frame to a network associated with the service.
Abstract:
Method and apparatus for transmitting messages in a two-way paging system are disclosed. Reply codes corresponding to portions of a message to be transmitted by a base station and received by a mobile pager device are computed either at the base station or at the pager according to various embodiments. The reply codes, which are typically shorter and require less bandwidth than the full text to which they correspond, are incorporated by the pager into reply messages when the user of the pager device wishes to refer to portions of the text of the received message in his reply. The present invention advantageously allows the user of a pager device to respond to a received message by transmitting a reply message that incorporates part of the text of the original received message without significantly increasing the bandwidth required to transmit the response.
Abstract:
Improved image quality is realized in a parallax-free teleconferencing display by increasing the camera light budget, that is, by increasing the light available to the camera, while maintaining a common optic axis between the camera and the display screen. Light-attenuating devices, such as color filters, are repositioned out of the path of light entering the camera. In this manner, image quality is improved while color capability is maintained.
Abstract:
A receiver includes an interference canceller circuit which receives a corrupted signal and makes an estimate of the desired signal. Subsequently, an estimate of the interference signal is determined by subtracting the estimated desired signal from a delayed version of the received signal. The receiver forms a final estimate of the desired signal by subtracting the estimated interference from a second delayed version of the received signal.
Abstract:
Slotted Aloha-NOMA (SAN) protocol is an uncoordinated, non-orthogonal, random access protocol that exploits the simplicity of SA (Slotted Aloha) and the superior throughput of non-orthogonal multiple access (NOMA) and its ability to resolve collisions via use of successive interference cancellation (SIC) receiver. In SAN protocol, the SIC receiver at the IoT gateway adaptively learns the number of active devices (which is not known a priori) using multiple hypothesis testing in order to successfully distinguish between signals transmitted from different IoT devices.
Abstract:
A system for performing non-invasive networked medical procedures including a number of in vivo medical devices, a communication path between at least two of the devices, an ex vivo control unit to control the behavior of the devices, and a wireless communication path between the control unit and at least one of the devices. An associated method for performing non-invasive networked medical procedures is also provided. Further included is a simulation method that utilizes accurate electromagnetic field simulations, using a software based test bench, to determine the maximum allowable transmitted power levels from in vivo devices to achieve a required bit error rates (BER) at an in vivo or ex vivo node (receiver) while maintaining the specific absorption rate (SAR) under a required threshold.

Abstract:
This invention is in the domain of minimally invasive surgery and is a method and apparatus that transforms and displays images of internal organs and tissues taken from internally located imaging devices on external skin. The image displayed on the skin aligns with the actual physical location, orientation, and size of the internal organs and tissues in a way that viewers have the perception that the skin is transparent. This method and apparatus enables surgeons to have the same hand-eye coordination as in an open surgery during a minimally invasive surgery.
Abstract:
An E-Tree is disclosed which includes a root node associated with a Metro Ethernet network. The E-Tree includes a first Virtual Bridge (VB), associated with the root node, which is configured to process Ethernet traffic, and a second node associated with the Metro Ethernet network. The E-Tree includes a second VB, associated with the second node, configured to process Ethernet traffic and having a first connection between the first VB and the second VB. The second VB is configured to be able to send Ethernet traffic to the first VB via the first connection, if appropriate. In the event there is a second connection between the second VB and a third VB and the second connection has been assigned a down direction from the point of view of the second VB, the second VB is not permitted to send traffic received from the second connection to another connection which from the point of view of the second VB has been assigned a down direction.
Abstract:
A Layer 2 Virtual Private Network (L2VPN) system is provided. A Provider Backbone Bridge (PBB) network is provided which comprises a plurality of sites to be connected via a L2VPN. The plurality of sites in the PBB network is connected using a plurality of provider backbone trunks that includes a Provider Backbone Transport (PBT) trunk or a Provider Backbone Bridge Traffic Engineering (PBB-TE) trunk, such that the L2VPN includes the plurality of sites.
