Abstract: A wave energy converter (10) for extracting useful energy from wave motion. The converter (10) comprises an active float (12) that is arranged to float on the water, and being arranged to heave and surge in response to wave motion acting on the active float, and an elongate reactive body (14) that is arranged to be suspended in a substantially submerged state into the water and having sufficient surface area and length such that it pitches in response to wave motion-acting on the reactive body. The active float (12) and reactive body (14) are pivotably coupled for pivotable movement relative to each other about a single pivot axis (16) in response to heaving and surging of the active float and pitching of the reactive body. The converter also comprises a power output system that is driven by the pivotable movement about the pivot axis to capture the useful energy.

Abstract: A handheld measurement device (10) for enabling a user to measure a person's muscle strength and range of motion associated with a limb movement about a joint in a movement plane. The device comprises a contact surface (28) that is arranged to contact a part of the person's limb, a 3D orientation sensor that is arranged to sense the 3D orientation of the device in 3D space and generate representative 3D orientation signals during the limb movement, and a force sensor that is arranged to sense the force applied by the person's limb to the contact surface and generate representative force signals. A control system receives the 3D orientation and force signals and processes those signals to generate force data and angular rotation data.

Abstract: A hand orthosis for assisting gripping by persons with a disability affecting hand function, comprises a thumb part, a hand part which fits around a user's hand between the thumb and knuckles, a forearm part which fits to a user's forearm above the hand. The orthosis includes a flexible connecting element connected at one end to the thumb part and which is movably coupled to the hand part and connected at another end to the forearm part such that when the orthosis is fitted to a user, extension of the user's wrist draws the user's thumb towards the user's index finger to form a grip. A powered embodiment of the orthosis is also disclosed.
