Abstract: The present disclosure provides a floating touch camera module, a display device and a touch method. The floating touch camera module includes: a lens with a light collection surface and a light emitting surface; an image sensor at one side of the light emitting surface of the lens, the image sensor configured to receive light rays from the lens and form sensing information; and an infrared cut filter film at one side of a light incident surface of the image sensor and configured to filter out infrared light rays. The infrared cut filter film is movable relative to the lens between a first position at which the infrared cut filter film directly faces the lens and a second position at which the infrared cut filter film is offset from the lens, thereby enabling the floating touch camera module to switch between a photographing mode and a touch mode.

Abstract: The present application relates to a smart knee joint for a human lower limb exoskeleton, a prosthesis, and an orthosis. The smart knee joint reproduces part or all of the biomechanics of the knee joint of the human body by using a motor driving unit and a controllable elastic energy storage unit based on a magnetorheological damper. The motor driving unit here can be replaced with a controllable damping unit. The smart knee joint is developed for helping amputees or patients with impaired mobility regain/repair natural gaits and also reduce their burden of walking. The motor drive unit operates in a generator mode and an actuator mode. Energy harvesting technologies are exploited to reduce the power consumption of the smart knee joint then to prolong the working time. In addition, the controllable elastic energy storage unit based on the magnetorheological damper can further reduce the energy consumption of the smart knee joint, and also simplify the control of the knee joint.

Abstract: An optical communication device includes two optical transmitting devices, two optical receiving devices, an optical path component, and an optical fiber adapter. A first converging lens packaged in each of the optical transmitting devices converges a light beam emitted by a light source, and provides the converged light beam for the optical path component.

The optical path of the optical communication device is simplified and the process costs are reduced. In addition, the quantity of used lenses is reduced, correspondingly reducing the quantity of optical coupling dimensions between mechanical parts and improving production efficiency of combined passive optical network (Combo PON) products.

Abstract: The present application provides a human joint energy harvesting apparatus for capturing the biomechanical energy of a joint to generate electrical energy. The generated electrical energy may provide a real-time power supply to the wearable electronics. The apparatus employs a linear slide rail mechanism and cooperates with the user's first limb and second limb to form a slider-crank mechanism, which converts the rotating motion of the joint into a linear motion of the linear slide rail mechanism. The bending beam converts the linear motion of the linear slide rail mechanism into a bending motion. A piezoelectric film may be bonded to the upper and lower surfaces of the bending beam. During walking, the bending beam is deformed, causing the piezoelectric film to be stretched or compressed to generate electrical energy. To harvest more energy, the bending beam used in the apparatus is designed to be subjected to forced motion and free vibration, and a proof mass is attached to it.
