The present invention relates to a method for determining a utilization level (UL; ULtot) indicating a degree of utilization of a re-usable cutting accessory (4) for endoscopic surgery, such as an arthroscopic shaver blade, removably connectable to a handpiece (2) comprising a motor (21) driving the cutting accessory (4) during surgical procedures. The method provides a reliable measure of the utilization level of the cutting accessory (4) by determining the utilization level (UL) of the cutting accessory (4) through calculation of at least one utilization factor (UF1, UF2) that is calculated based on a torque (40) measured when said cutting accessory (4) is driven by said motor (21).

A hybrid Media Gateway Control Function (MGCF) implemented in a 3G wireless telecommunications network that provides access to multimedia services and IP networks for a mobile terminal operating in a circuit-switched (CS) mode. The hybrid MGCF includes a CS-specific signaling mechanism that exchanges CS-specific control signaling with a radio access network (RAN) serving the mobile terminal, and a SIP signaling mechanism that exchanges SIP control signaling with a Call State Control Function (CSCF) that accesses multimedia services for the mobile terminal. A converter in the hybrid MGCF converts the CS-specific control signaling into SIP control signaling, and sends the SIP signaling to the SIP signaling mechanism. A switching control function within the hybrid MGCF controls a Media Gateway (MGW) to route media payload from the RAN to destinations such as multimedia IP networks.

The present invention is directed to devices and methods that provide a user of a decentralized asynchronous parallel-configured wireless communication system for voice, data and live digital video streaming communication with the ability to select various communication paths and calling bandwidths as needed. The system uses a novel Time-Shared Full Duplex (TSFD) protocol for communications. The TSFD protocol allows the transmission of live digital video signals from one wireless device to another wireless device. The system provides local communication as well as optional links to external networks, and does not require a synchronous centralized switching center. It further provides secure operation, emergency notification and a way to collect revenue from the system, and allows for control of the operational state of the internal network and optional remote control of the operational state control of systems external to the network.

A method and system for power management including device controller-based device use evaluation and power-state control provides improved performance in a power-managed processing system. Per-device usage information is measured and evaluated during process execution and is retrieved from the device controller upon a context switch, so that upon reactivation of the process, the previous usage evaluation state can be restored. The device controller can then provide for per-process control of attached device power management states without intervention by the processor and without losing the historical evaluation state when a process is switched out. The device controller can control power-saving states of connected devices in conformity with the usage evaluation without processor intervention and across multiple process execution slices. The device controller may be a memory controller and the controlled devices memory modules or banks within modules if individual banks can be power-managed. Local thresholds provide the decision-making mechanism for each controlled device. The thresholds may be history-based, fixed or adaptive and are generally set initially by the operating system and may be updated by the memory controller adaptively or using historical collected usage evaluation counts or alternatively by the operating system via a system processor.

Configuring a node. A method includes determining a current state of a target node. The current state of the target node refers to objects currently deployed or running in the remote target node. It includes at least one of an operating system, one or more applications, or configuration setting at the target node. The method further includes determining a desired state for the target node to change the current state. The method further includes accessing a dependency graph based on the version of an agent running on the target node. The dependency graph is supplied to a state machine. The state machine is particular to the target node. The state machine using the current state of the target node, the desired state and the dependency graph, performs operations to drive the target node toward its goal.

The present invention relates to a system and method of viewing pairs of perspective images of 3-D objects (i.e. stereoscopic image pairs) displayed from a CRT display surface in a time-multiplexed or field-sequential manner, and more particularly to a universal method of generating control signals for synchronously changing the optical state of liquid crystal (LC) shutter panels through which the time-multiplexed perspective. images can be sequentially viewed in a substantially flicker-free manner by the left and right eyes of a human viewer, independent of whether the images are displayed on NTSC, PAL, VGA or SVGA styled CRT display devices.

A technique dynamically protects against failure of a head-end node of one or more primary Traffic Engineering Label Switched Paths (TE-LSPs) in a computer network. According to the novel technique, a neighboring upstream node (“protecting node”) of the head-end node learns of the primary TE-LSPs (and their respective state control blocks) extending from the head-end node to one or more address prefixes. The protecting node establishes a repair TE-LSP for each of the primary TE-LSPs to a corresponding downstream neighboring node of the head-end node (a “next-next-hop”). In response to detecting a failure of the head-end node, the protecting node locally reroutes traffic destined for the address prefixes to an appropriate repair TE-LSP. Due to the failure of the head-end node, the protecting node then refreshes the states of the primary TE-LSPs using replicated state control blocks accordingly, until the repair TE-LSPs are no longer needed.

The automated remotely located power adapter is connectable between the external power supply and the data processing system for supplying external electrical power to charge the battery within the data processing system and automatically shuts off the external electrical power when the data processing system indicates that the battery is fully charged.

When a terminal enters a cell of a personal-use base station (NBTS) arranged in a certain location area, the terminal receives a location area identifier having a number that is different from an identifier of the location area, and transmits a location updating request with the reception of the location area identifier as a trigger. On receiving the location updating request, a VLR or an NRNC having a registration table, in which the ID of the personal-use base station and the ID of a terminal allowed to use the personal-use base station are registered, judges whether the terminal issued the location updating request is the terminal allowed to use the personal-use base station by referring to the registration table. If the terminal issued the location updating request corresponds to the terminal allowed to use the personal-use base station, the terminal is placed under a status where it is capable of performing communication in the cell, and if not, the terminal is placed under a status where it is incapable of performing communication in the cell.

A system and method of ensuring a requested Quality of Service (QoS) for a media flow that is transported through multiple transport networks.

An emergency telephone call is supported and routed to a Public Safety Answering Point (PSAP) in an IP based packet switched wireless communications network. An activate PDP context request is sent from a user equipment to the network. A parameter in the activate PDP context request indicates that the PDP context will be used to transfer an emergency call. An activate PDP context accept message is returned from the support node to the user equipment. The activate PDP context accept message acknowledges the activate PDP context request message and provides the address of a call state control function. A call setup request transferred to the call state control function includes the Service Area Identity (SAI). The call state control function selects a PSAP based, at least in part, on the SAI included in the call setup request and forwards the emergency call to the selected PSAP.

In a first embodiment of the invention, when an Activate PDP Context Request message is forwarded to a Service GPRS Support Node (SGSN), the SGSN creates a Create PDP Context Request message and forwards it to a Gateway GPRS Support Node (GGSN). In response to the Create PDP Context Request forwarded by the SGSN, the GGSN creates a Create PDP Context Response message. When a PDP context is created by the GGSN, the GGSN associates a Globally Unique Charging Identification (GCI) with the PDP context. Then, the Create PDP Context Response including the GCI is forwarded to the SGSN. The GCI is sent from the SGSN to the UE and from the UE to the CSCF. In a second embodiment of the invention, the GCI is sent from the SGSN or the GGSN directly to the Call State Control Function (CSCF). Sending the GCI can be performed either autonomously or based on a request from the CSCF. In either embodiment, the CSCF can send the GCI to a second network which performs processing, such as billing, from data collected from call detail records associated with the GCI.

In a vehicle control system performing collision avoiding control when a collision with a preceding vehicle cannot be avoided by normal running condition control, driving safety is improved by prompting a driver to intervene in the vehicle's control in a reliable manner. When a set switch is turned on in the "cancel" state, the transition to the "in-control, inter-vehicle distance control" sub-state occurs and an inter-vehicle distance control is performed. If a collision with a preceding vehicle cannot be avoided by the inter-vehicle distance control (if the collision alarm flag XA=1), transition to the "in-control, collision alarm" sub-state occurs and a collision alarm is generated. If the acceleration required for avoiding collision is further increased (if the collision avoiding control flag XC=1), the state transits to the "in-control, collision avoiding control" sub-state, and a collision avoiding control is performed.
