Abstract: A wave energy converter comprises a submerged buoyant vessel (10) that can react directly with the seabed using neutrally buoyant taut tethers (19) at depths that characterize the continental shelf. The vessel (10) is held by a taut vertical mooring line (12) of controllable length and a taut vertical upper line (17) of controllable length connected to a surface float (15). These lines (12, 17) have elastic sections, allowing the vessel (10) to follow an orbital path in response to swell from any direction. By varying the length of these lines (12, 17) the submersion of the vessel (10) can be varied dynamically according to wave height. By varying the tension of these lines (12, 17) the natural oscillation period of the vessel (10) can be varied dynamically in response to the swell period.

The filtration module assembly may enable an improved manifold arrangement used to communicate fluids to and from a filtration system comprising a plurality of such modules and the configurations of the present invention may facilitate improved operation of such filtration systems.

Abstract: Dynamic tuning of the oscillating buoyant body of a wave energy converter over a range of periods that characterize energetic swell is achieved by controlling the ratio of total mass moment of inertia to restoring force and by controlling wave bridging. Mass is varied by locking and unlocking neutrally buoyant masses or by trapping and releasing seawater. For surging, water-plane area is forcibly varied. For rotational variants of heaving and surging and for pitching, the radius of gyration is varied. Invariant mass is reduced by using materials and structures with high ratios of strength to weight. Invariant added mass is reduced by streamlining, by constant radius body profiles and by keeping moving structures out of the water. Added mass is varied by using variable angle fins. Control of wave bridging, for a pitching body, including a wave following device, is by locking and unlocking serial segments of the buoyant body.

Abstract: A pendulum combining balanced and eccentric masses oscillates with a period that is rapidly and continuously varied by shifting the balanced masses and eccentric mass to and from the rotational axis, by controlling the amplitude of oscillation and, in a rolling embodiment, by varying the curvature of the rolling surface. Long period oscillations can be achieved without the large heights required by an equivalent conventional pendulum. The pendulum can be substantially isochronous. The pendulum can be applied to harvesting vibrational energy and especially to wave energy extraction by dynamically achieving resonance over the typical frequency range of energetic ocean swell.

Abstract: A wave energy converter can be dynamically tuned to achieve resonance with ocean swell by varying the geometry of an attached submerged water-filled vessel (41).

Abstract: Controlling accesses to target devices such as disk drives by modifying the duty cycle profile of those devices to improve device reliability is disclosed. The utilization of a target device is monitored, and if a device is being overused, that device is given a rest period by reserving it for a special initiator that does not send any commands to the device for a certain period of time. This reduced utilization has the effect of increasing the reliability of the target device. This period of time also adds a delay to the processing of commands for the target device being overutilized so that the device becomes less responsive. This performance penalty creates pressure on system administrators to reduce the number of commands sent to that target device and/or move data to proper devices (that can handle the high number of accesses).

Abstract: Monitoring in switch networks is disclosed. Ports in a switch may include monitoring circuitry and a monitoring tap which allows traffic data to be diverted for monitoring prior to any significant transformation of the traffic by the regular port logic. Furthermore, the monitoring circuitry can receive signaling and convert it for subsequent analysis by a protocol analyzer. The ports and paths in the switch network can be configured to create monitor paths to enable diverted traffic data to be passed through the network to locations where a protocol analyzer can be easily attached. With wide bandwidth ports, there is no disruption to the system. Because only a copy of the data is routed to the analyzer, there is no change to the original signal path and latency is identical with or without the analyzer.
