Abstract: A predictive clock controller is provided for modifying the frequency of a clock signal provided to a processing unit based on knowledge of the power usage by the application running on the processing unit during different execution periods. The predictive clock controller counts barrier syncs for the application, so as to determine where the application is in its sync schedule. The predictive clock controller is able to determine from the number of counted syncs, when the application will transition from one execution period to another execution period with different power requirements, and to adjust the clock frequency accordingly.

Abstract: A case or support cradle for a fall arrest device has a shape or configuration enabling rolling of the case or cradle along an arcuate path. The rollable case or cradle allows the fall arrest device received therein to smoothly follow a user's movements around a work site, thereby protecting the device from damage due to dragging or scraping along a floor surface.

Abstract: A data processing apparatus is provided that includes message obtaining circuitry that obtains, for transmission over a first cellular communication channel to an endpoint device, an outgoing SMS message containing an encrypted payload and an identifier corresponding to the endpoint device. Extraction circuitry extracts the encrypted payload from the outgoing SMS message and produces an extracted encrypted payload, and extracts the identifier corresponding to the endpoint device from the outgoing SMS message. Wrap circuitry wraps bytes that make up the SMS message in an outgoing data packet and communication circuitry transmits, to the endpoint device or a server, the outgoing data packet on a second data communication channel. The outgoing data packet is of a type other than an SMS message.

Abstract: A fall arrest device having a rotatable drum with a safety line thereon, the fall arrest device comprising at least one energy absorber ring configured to absorb energy in the event of a fall and positioned to a side of the drum and between a first component configured to rotate with the drum and a second component configured to activate based upon the speed of rotation of the drum.

Abstract: A descender device, typically for use in a fall arrest system, that enables a suspended body to be lowered, and includes a descent line and a release element to be actuated by a person. The release element is arranged in a restraint configuration to inhibit the descent line from being deployed and in a release configuration to permit the descent line to be deployed. A restraint arrangement is arranged prior to deployment of the descent line, to clamp or pinch a length of flexible line thereby to inhibit deployment of the descent line, the restraint arrangement being reconfigurable upon release of the release element to permit the descent line to be deployed.

Abstract: 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.

Abstract: A traveller for safety line for a fall arrest system has a slot extending to the exterior of the traveller and a safety line locating shuttle provided on-board the traveller wherein the safety line locating shuttle is movable relative to the slot along a predetermined path in a direction across the slot. This aids in accurate positioning of the safety line with respect to the traveller. The slot can be defined between opposed slot edges which are movable relative to one another to reconfigure the slot.

Abstract: 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.
