Abstract: A motorized wheelchair chassis includes a frame assembly having a first frame element that supports first and second caster wheels at an end of the first frame element. The first frame element is designed to support a seat assembly, a battery support assembly secured to an underside of the frame assembly, at least one battery, first and second power drive assemblies disposed on lateral sides of the battery support assembly, and first and second drive wheels driven by the first and second power drive assemblies, respectively. The frame assembly further comprises a second frame element that is secured to the battery support assembly. The first frame element is supported onto the second frame element via a coupling structure comprising a ball-joint bearing permitting relative movement of the first frame element with respect to the second frame element in more than two degrees of freedom within a limited range of movement.

Abstract: A bilateral upper limb exercise device (10) for exercising a user's arms comprising a central mounting structure (12) that is mountable to a fixed surface or structure (15), left and right limb supports (14a, 14b) for supporting the forearm and/or hand of a respective arm of the user, and a pair of articulated linkage arms (22a, 22b) that are pivotably coupled to opposite sides of the central mounting structure (12) and which are arranged to support a respective limb support (14a, 14b) for movement in at least two degrees of freedom in a two-dimensional (2D) movement plane. A mirroring mechanism is also operatively coupled to the articulated linkage arms (22a, 22b) such that movement of the opposing limb support relative to a central line of symmetry of the device.

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 portable handheld device (20) for use by a therapist to measure angles and forces associated with a joint of a patient. The device (20) comprises a housing (22) with a contact pad (26) that is arranged to contact a body part associated with the joint and a hand piece (24) for the therapist to grip. A goniometer is mounted within the housing (22) and is arranged to measure the angular position of the body part when it is in contact with the contact pad (26) and generate representative angle data. A force sensor is coupled to the contact pad (26) and is arranged to measure the force applied by the body part to the contact pad (26) and generate representative force data. A control system is also provided and is arranged to operate the goniometer and force sensor simultaneously to capture measurements of angle data and force data simultaneously.
