Abstract: A method of forming an ohmic contact on a substrate composed of a wide-band gap semiconductor material includes: depositing a transition metal group metal on the substrate; annealing the substrate at a high temperature to cause a solid state chemical reaction between the substrate and the deposited metal that forms a modified layer in the substrate having modified properties different than the substrate, and by-products composed of a silicide and a nanocrystalline graphite layer; selectively etching the substrate to remove one or more of the by-products of the solid state chemical reaction from a surface of the substrate; and depositing a metal film composed of a transition group metal over the modified layer on the substrate to form the ohmic contact. The modified layer permits formation of the ohmic contact without high temperature annealing after depositing the metal film.

Abstract: Methods and system perform tool tracking during minimally invasive robotic surgery. Tool states are determined using triangulation techniques or a Bayesian filter from either or both non-endoscopically derived and endoscopically derived tool state information, or from either or both non-visually derived and visually derived tool state information. The non-endoscopically derived tool state information is derived from sensor data provided either by sensors associated with a mechanism for manipulating the tool, or sensors capable of detecting identifiable signals emanating or reflecting from the tool and indicative of its position, or external cameras viewing an end of the tool extending out of the body. The endoscopically derived tool state information is derived from image data provided by an endoscope inserted in the body so as to view the tool.

Abstract: Disclosed are, inter alia, methods, apparatus, data structures, computer-readable media, mechanisms, and means for establishing a call across a network. For example, the network may include a first edge switch, a second edge switch, and an ATM core network coupled to the first and the second edge switches and configured to allow the second edge switch to communicate with the first edge switch. The second edge switch, being responsive to a received Q.2630.1 AAL2 message, is configured to send a first Private Network-Network Interface (PNNI) setup message to the first edge switch as part of establishing a call between or through one or more of the first and the second edge switches.

Abstract: Methods and apparatus are disclosed for changing the bandwidth or other traffic characteristic of an established packet call in response to an identification of the requirements of the call. In one implementation, an integrated access device (“IAD”) is used to connect one or more devices to a packet network. When a device goes off-hook, a call is established through the packet network with an initial bandwidth, such as that which will support a compressed and silence suppressed voice call. The IAD monitors the received signal to determine whether a type of traffic is detected which requires a different call characterization. A request may be made to modify the traffic characterization of the established call to match the detected call characterization. In an ATM network, Q.9231.x may be used to request a change in the bandwidth of the originally established call.

Abstract: A method and system for establishing a call between two endpoints residing on different media gateways in a decomposed voice over packet architecture. Cluster attributes identifying alternate bearer possibilities are exchanged between media gateways as part of capabilities negotiation which occurs during call setup conducted by an external call control element over a core network. The media gateways analyze the cluster attributes to determine whether bearer possibilities exist apart from the core network. If an alternate bearer possibility exists, the alternate is employed and the call is established via the alternate bearer directly between the media gateways, thus bypassing the core network.
