Abstract: A heat pump system, a heat management method and a vehicle are provided. The heat pump system includes an integrated heat exchanger integrated with a superconducting liquid flow passage and a refrigerant flow passage. The refrigerant flow passage is provided inside an on-board refrigerant circulation loop and is used for cooling and/or heating to adjust the temperature within a passenger compartment of a vehicle. The superconducting liquid flow passage is in communication with a motor heat dissipating conduit, for absorbing the heat generated by an on board motor and transferring the heat to the integrated heat exchanger by means of phase change heat transfer. The heat pump system can increase the energy utilization rate for the vehicle and reduce the allowable ambient temperature of the heat pump system.

Abstract: Described herein is a method for producing a viscose solution including a step of adding alkyl polyglycoside (APG) prior to and/or during xanthation of alkali cellulose. When APG is added prior to or during xanthation of alkali cellulose, the reactivity between alkali cellulose and CS2 could be increased and the xanthation could be accelerated, as a result of which formation of agglomerates and/or lumps in the obtained viscose solution and then the obtained viscose fiber spun therefrom is significantly reduced, relative to the situation when conventional surfactants such as phenyl ethoxylate are added likewise. Also described herein is a viscose solution obtained by the foresaid method, and a method for producing viscose fiber with the foresaid viscose solution or including the foresaid method.

Abstract: An optical navigation device, such as an optical navigation joystick or mouse, includes an internal redirector which may be separate or formed from material of a touch surface of the optical device. The redirector is disposed at an angle with respect to a plane of the touch surface, operative to reflect light which would otherwise strike the touch surface at a low angle and be internally reflected. The light may be reflected in a direction away from a light sensor of the device, reducing sensed internally reflected light, or may be reflected into the touch surface at a higher angle, potentially increasing a quantity of good signal. The redirector may also include portions which block light directly emitted from a light emitter, or reflected off other surfaces of the navigation device.
