Abstract: A method for characterising a mechanical property of a material. The method comprises the steps of providing the material having a deformable portion and providing a device having an optical element that is arranged to detect electromagnetic radiation.

Abstract: The described knee rehabilitation device can include any suitable component. In some implementations, however, it includes a sitting surface that is configured to support a user; a knee arm that comprises a leg coupling mechanism, that is pivotally coupled to the rehabilitation device, and that is configured to pivot through a range of motion; and a drive mechanism that is configured to force the knee arm through the range of motion. In some cases, the drive mechanism includes a first hard stop that prevents the knee arm from extending past a first set point, and the drive mechanism further includes a second hard stop that prevents the knee arm from being retracted past a second set point. In some cases, the device is further configured to be programmed to electronically limit the knee arm's range of motion. Other implementations are discussed.

Abstract: The present disclosure provides a device for evaluating a mechanical property of a material. The device comprises a sensing layer that has a contact surface for contacting a surface area of the material. The sensing layer has a property or dimension that is pressure sensitive. The device also comprises a detector arranged to detect electromagnetic radiation that propagates through at least the sensing layer. The device is arranged such that, when the contact surface of the sensing layer is in contact with the surface area of the material and a load is applied on at least a portion of the surface area of the material, the detected electromagnetic radiation can be used to determine stress within a portion of the sensing layer, the determined stress being indicative of the mechanical property of the material.

Abstract: A self-inflating and self-deflating orally ingestible device that is able to traverse the entirety of the alimentary canal is described. In one embodiment, the device includes a closed balloon having a surface separating an enclosed space internal to the balloon from a space external to the balloon, at least one self-sealing valve integrated with the surface of the balloon to provide access to the enclosed space internal to the balloon from the space external to the balloon, a vent comprised of a dissolvable seal integrated with the surface of the balloon, and a vessel located within the enclosed space internal to the balloon to separate internal contents of the vessel from the enclosed space internal to the balloon.

Abstract: A drink holder that is designed to adjust to fit in any angle rod holder and can be easily removed and replaced.
