摘要： Opto-electric devices can evaluate convolutional neural networks with reduced power consumption and higher speeds using optical metamaterial structures. Methods and systems for convolution of an input vector f with a kernel k can include a first optical element that is adjustable according to the input vector f and a second optical element that is adjustable according to the kernel k, where either or both elements can include adjustable optical metasurfaces. In some approaches, the second optical element is adjustable according to a Fourier transform of the kernel k and is interposed between first and second lenses or volumetric metamaterials implementing Fourier and inverse Fourier transforms, respectively.

摘要： A water cooling system for showers has a water tank filled with water to be cooled, and a heat exchange loop which includes an internal heat exchange (HX) evaporator immersed into the water within the water tank, and a condenser HX unit positioned externally above the internal evaporator unit. A refrigerant in the loop absorbs the heat from the water in the water tank, circulates in the HX loop, and passes to the condenser HX unit to release heat to ambient air. The water cooling process is passive and does not require any form of external energy. The subject heat transport attains a minimal thermal resistance by two-phase evaporation and condensation process (heat piping) which achieves positive flow at as low as 0.2°C - 1°C temperature difference between the ambient air and the tank water.

摘要： A knockdown, portable lift is relatively compact and lightweight for transport and use where there is no existing means for lifting a load between a lower surface and an upper surface or where the existing means cannot be used. Components of the lift are stored in a base portion of the lift and are assembled on site for forming a lift frame extending between the upper and lower surfaces. A platform and drive assembly are supported on the lift frame and are driven together up and down tracks on each side of the lift frame using a rotary drive, such as a hand crank or electric motor, to power the drive assembly. The drive assembly is operable by a person on or off the platform from either the upper or lower surface or traversing stairs over which the platform is moving. The drive assembly incorporates a unique overspeed braking system and a unique clutch arrangement.
