| 20100215014 | Quasi Synchronous Transmission in Cellular Networks - Aspects of the invention include a root node of a wireless communication infrastructure that buffers data packets for transmission by base stations over an air interface. The root node determines a time delay for transmission of a data packet from the root node to each base station, a maximum time delay of those time delays, and a timing latency based upon the maximum time delay. The root node transmits the timing latency to the base stations. In response, each base station initiates transmission of data packets received by the root node after expiration of the timing latency. Alternatively, the root node, instead of the base stations, may buffer the data packets, and transmit them so that they arrive at the base stations at substantially the same time. | 08-26-2010 |
| 20100278084 | Apparatus, Communication System and Methods for Enabling Spectrum Access - Embodiments of the invention provide for allocating spectrum in a wireless communication system that supports simultaneously at least a first mode of operation and a second mode of operation. Logic is arranged for determining a proportion of spectrum required for the wireless communication unit to operate simultaneously in both the first mode of operation and the second mode of operation. Logic for allocating spectrum allocates a temporary guard band between a first portion of spectrum for the first mode of operation and a second portion of spectrum for the second mode of operation for use whilst the wireless communication unit operates simultaneously in the first mode of operation and second mode of operation. | 11-04-2010 |

| 20090032785 | SAFETY DEVICE - A safety device for a fall arrest system comprises: a body, attachment means for attaching the safety device to a support structure, a drum mounted for rotation relative to the body, a safety line wound on the drum, a speed sensitive clutch connected to the drum, and a linear energy absorber connecting the body to the attachment means, in which the speed sensitive clutch is adapted to respond to rotation of the drum relative to the body in a direction tending to unwind the safety line from the drum and above a predetermined speed by locking the drum against further rotation in said direction relative to the body, and the linear energy absorber is adapted to respond, when the speed sensitive clutch has locked the drum, to an applied load along the safety line greater than a threshold value by deploying and absorbing energy so that the attachment means moves away from the body. | 02-05-2009 |
| 20090260919 | SAFETY LINE ANCHOR - An anchor assembly for an elongate safety line comprises safety line gripping means connected to a bracket means by a releasable clamping means. The releasable clamping means comprises a tapered clamp formed by first and second opposed clamping surfaces defining a tapered space between them, a tapered member having a tapered profile matching the tapered space and a clamping element adapted to urge the first and second clamping surfaces together to clamp the tapered member between them. | 10-22-2009 |
| 20100236867 | Rotational Energy Absorber and Fall Arrest System - A rotational energy absorber typically for use in a fall arrest system has a coiler, a length of plastically deformable strip and a deformer structure. The plastically deformable strip has a first end attached to the coiler and a second free end and extends past the deformer structure at a position between the first and second ends. Relative rotation of the coiler member and deformer structure causes the strip to be drawn past the deformer structure, plastically deforming the strip and winding the strip coil form about the coiler member. | 09-23-2010 |
| 20100252366 | Fall Arrest System Safety Device - A safety device for use in a fall arrest system, has a safety line drum mounted for rotation and a speed responsive engagement mechanism responsive to the speed of rotation of the drum, which is activated above a predetermined rotational speed of the drum to deploy an energy absorber. A rotational transmission member (which may be in the form of a shaft) is coupled, via the speed responsive engagement mechanism, when activated, to rotate with the drum. The energy absorber is deployed in response to operation of the rotational transmission member. The speed responsive engagement mechanism may be mounted intermediate the drum and the energy absorber for ease of replacement. | 10-07-2010 |
| 20110088976 | SPEED RESPONSIVE ENGAGEMENT DEVICE - A speed responsive engagement device comprises: a wheel arranged for rotation about a first axis and having a plurality of outwardly projecting spaced apart teeth with each pair of adjacent teeth being separated by a circumferential surface with a constant radius; a pawl arranged for pivotal movement about a second axis between a first unengaged position and a second engaged position in which the pawl engages one of said teeth and contacts a circumferential surface; and a resilient means arranged to urge said pawl towards the first position when the pawl is not in contact with a circumferential surface. When the wheel rotates in a first direction each tooth contacts the pawl, generating an oscillating movement of the pawl from the first position towards the second position with an amplitude dependent on the speed of the rotation. When the speed of rotation reaches a predetermined value the oscillating movement brings the pawl into the engaged position, preventing further rotation of the wheel in said first direction. | 04-21-2011 |
