Abstract: This disclosure is directed towards a hydraulic system for providing auxiliary drive to a powertrain (11) and a hydraulic circuit (12) by storing and releasing hydraulic fluid using an accumulator (29). A hydraulic drive system (10) comprises an engine (14), a hydraulic machine (22) operably connected to the engine (14), a pump (17), an accumulator (29) and at least one valve (20, 27). The pump (17) is driven by the engine (14) and is configured to control a hydraulic circuit (12). The accumulator (29) is fluidly connected to the hydraulic circuit (21) and the hydraulic machine (22). In one instance, the at least one valve (20, 27) is operable to direct pressurised fluid from at least one of the hydraulic machine (22) and the pump (17) to charge the accumulator (29). Alternatively, the at least one valve (20, 27) is operable to direct pressurised fluid from the accumulator (29) to at least one of the hydraulic machine (22) and the hydraulic circuit (21).

Abstract: Systems designed to train and certify persons to act as at least one responsible person(s) for decision making and management operations as part of an emergency response at incidents that contain at least one hazard zone; such hazard zone defined as any work area which contains a hazard that can injure or kill, for example, burning structures, hazardous material incidents, roadways with active traffic, natural disaster sites, and/or other emergency response scenes.

Abstract: A method of unloading liquid from a reservoir includes deploying a pumping system into a wellbore to a location proximate the reservoir using a cable. The pumping system includes a motor, an isolation device, and a pump. The method further includes setting the isolation device, thereby rotationally fixing the pumping system to a tubular string disposed in the wellbore and isolating an inlet of the pump from an outlet of the pump; supplying a power signal from the surface to the motor via the cable, thereby operating the pump and lowering a liquid level in the tubular string to a level proximate the reservoir; unsetting the isolation device; and removing the pump assembly from the wellbore using the cable.

Abstract: The present disclosure is directed at a method and system for shaping a membrane a capacitive micromachined ultrasonic transducer, or CMUT. A bias voltage is asymmetrically applied to a membrane of the CMUT such that the membrane is directed to send ultrasonic waves that propagate along a propagation axis that is not parallel with a propagation axis along which ultrasonic waves propagate when the bias voltage is symmetrically applied to the membrane. In this way, the ultrasonic waves that are generated using a CMUT array can be physically steered to or focused on a target. Steering and focusing ultrasonic waves by altering the shape of the membrane by asymmetrically biasing the membrane reduces grating lobes and can also be used as part of an adaptive control system that can improve ultrasound image quality.

Abstract: The present invention relates to a method and apparatus for registering three-dimensional ultrasound images to an external coordinate system, such as the coordinate system attached to a camera-based imaging system or the coordinate system used to define the movements of a surgical robot. The apparatus generally comprises a tool with markers that can be accurately and repeatably located in both the ultrasound and external coordinate systems. In the case of the surgical robot frame, this tool may be a component of the surgical robot itself, such as a portion of a surgical manipulator.

Abstract: A method of installing a sensor in a borehole drilled through underground formations, wherein the borehole is drilled with a hollow drill string formed from a series of pipe sections connected end-to-end, a drill bit being positioned at one end of the drill string and having an closure that is operable to provide an opening between the borehole and the inside of the drill string, the method comprising: drilling the borehole to a predetermined depth using the drill string and bit; partially withdrawing the drill string from the borehole so that the drill bit is positioned above the predetermined depth; lowering a sensor inside the drill string by means of a cable; operating the closure so that the sensor can pass out of the drill string into the borehole; and progressively withdrawing the drill string and drill bit from the borehole over the cable so as to leave the sensor in the borehole.

Abstract: This invention is a surgical clamp for the purpose of occluding the kidney or other organ and thereby obtaining a bloodless surgical field, while allowing the majority of the organ to remain normally perfused. Previous approaches are limited in ability to provide sufficient clamping force without damaging the oran. The invention comprises a first and second jaw, wherein the proximal ends of the two jaws, and the distal ends of the two jaws are connected by a strap, such that applying tension to the strap results in moving the relative positions of the jaws in a substantially parallel motion, which provide a clamping force to the organ. The jaws can be attached with a flexibly joint to a hollow shaft, such that a cable inside the shaft can be used to apply tension to the strap while maintaining the ability to pivot the jaws relative to the shaft.

Abstract: A spray head or spray head insert is provided for use in at least one of a shower head, an industrial spray head and an agricultural spray head including a plurality of groups of nozzles, each group of nozzles having at least two nozzles that are suitable for issuing jets of fluid from a surface of the spray head or spray head insert and are dimensioned and oriented, at least in use, so that fluid exiting the said at least two nozzles under pressure collides, interacts substantially unimpeded by surrounding structures and breaks into droplets.

Abstract: Methods are provided for assessing a patient being treated with a peroxisome-proliferator-activator-receptor-? (PPAR-?) agonist or a thiazolidinedione (TZD), or having a condition treatable with a peroxisome-proliferator-activator-receptor-?agonist or a thiazolidinedione. Methods include measuring a galectin-3 concentration or a change in a galectin-3 concentration in a body fluid of a patient being treated with a peroxisome-proliferator-activator-receptor-? agonist or a thiazolidinedione. A comparison to galectin-3 levels or changes in comparable patients provides information indicative of congestive heart risk.

Abstract: Methods for increasing sarcosine levels in a patient are provided. The methods include activating the PPAR? receptor. Increasing sarcosine levels can be used, for example, as part of a treatment for schizophrenia.

Abstract: A propulsion apparatus (20) which can be mounted to a wheel (8) (or integrally formed therewith) of a vehicle, for example a wheelchair. The propulsion apparatus (20) has a first portion which can be statically attached to either a rim of the wheel (8) or structural member which is rigidly attached to the wheel (8) projects therefrom. The propulsion apparatus (20) also has a second portion (23), which is pivotal about the rotational axis of the wheel (8). Furthermore, the propulsion apparatus (20) comprises coupling means which are interposed between the first and second portions so that when the second portion (23) is rotated about the axis of the wheel (8) it causes the first portion, and therefore also the wheel (8), to rotate.
