Abstract:
A safety apparatus is provided for use with a climbing harness of the kind including a waist belt (16, figure 3) having a rope (15) secured to opposite sides of the belt and passing round a pole (17) being climbed. The apparatus comprises a metal bracket (11) extending between and holding the opposite sides of the rope (15) closer together than would be the case in the absence of the bracket so as to maintain a greater length of the rope in frictional engagement with the circumference of the pole. The bracket (11) is slidable towards or away from the pole and is biassed towards the pole (17) by an elastic cord (20) passing around the pole and attached to opposite ends of the bracket.
Abstract:
A control telemetry device transmits a periodic synchronisation signal to remove telemetry devices to establish synchronisation. The time period between successive synchronisation transmissions is divided into a series of message specific time slots eg. for remote stations to transmit data or alarm signals to the control device thus avoiding transmission clashes caused by simultaneous transmission of data between the remote devices and the control device. Each device comprises a microcomputer 1, a clock 2, and a radio transmitter 8 and a receiver 9 each connectable to an antenna 10 via a switch 11 controlled by the microcomputer 1. The microcomputer of a remote device receives data from telemetry sensors via data-in lines 21 and sends signals to another device, such as an alarm, via data-out lines 22. The device may save power by the clock 'waking up' the microcomputer only for the duration of the synchronisation signal and for transmissions.
Abstract:
Various systems and methods for providing a vehicle control system are described herein. A system for managing a vehicle comprises: a vehicle control system of a vehicle having access to a network, including: a communication module to interface with at least one of: a mobile device, the vehicle, and environmental sensors coupled to the vehicle; and a configuration module to identify a mitigation operation to be taken when predetermined factors exist; wherein the vehicle control system is to identify a potential obstacle in a travel route of the vehicle and initiate a mitigation operation at the vehicle.

Abstract:
An embodiment may include circuitry to be comprised at least in part in a first host, and at least one process to be executed, at least in part, by the circutry. The circuitry may comprise a first port and a second port. The at least one process may detect, at least in part, a first bandwidth condition of the first port, and may associate, at least in part, in response at least in part to the first bandwidth condition, the first port and the second port with a port team. The second port may have been, prior to being associated, at least in part, with the port team, in a relatively lower power state compared to a relatively higher power state. The second port may be in the relatively higher power state after the second port is associated, at least in part, with the port team.
Abstract:
In an embodiment, an apparatus and method include reordering direct cache access (DCA) and non-DCA transfers so that DCA transfers are last transactions and therefore closer to an interrupt than non-DCA transfers. Embodiments also include coordinating with interrupt processing DCA requests for DCA and non-DCA transfers.
Abstract:
Techniques for accelerating network receive side processing of packets. Packets may be associated into flow groupings and stored in flow buffers. Packet headers that are available for TCP/IP processing may be provided for processing. If a payload associated with a header is not available for processing then a descriptor associated with the header is tagged as indicating the payload is not available for processing
Abstract:
A method for content-based presence communication entails receiving presence information, storing the presence information in any arbitrary data format, validating a subscription request to subscribe to the presence information by determining if information contained within the subscription request represents an authorized subscription relationship, and communicating the presence information when the presence information matches the subscription expression.
Abstract:
A method for managing a subscription to content-based presence information entails receiving a subscription- suspension message from a device at a presence service, identifying the subscription associated with the subscription- suspension message, suspending the subscription, and sending a response from the presence service to the device to notify the device that the subscription has been suspended. Suspending the subscription may involve accumulating notifications in a persistent data store. The method may further involve receiving a subscription-resumption message at the presence service to resume the subscription that was suspended.
