Abstract: A bistable liquid crystal spatial light modulating (SLM) device (SLM) device utilizes the homeotropic and bubble domain texture change of a cholesteric liquid crystal that is responsive to external stimuli, such as electric voltage, light and pressure. The SLM device is configured to be switched between the two stable textures of the bubble domain texture or the fingerprint texture. In addition, the SLM device may be switched between transparent and light-scattering states by the application of an electric field, light irradiation or physical/mechanical pressure. The light transmission state and the light-scattering states of the present invention are also stable in time at zero voltage, and are reversible upon the application of an external field at a different voltage, frequency or wavelength of light.

Abstract: An antagonistically actuated shape memory alloy (SMA) manipulator utilizes a pair of SMA actuators. The SMA actuators are configured, such that one actuator is trained to have a substantially linear or extended shape in its austenite phase, while the other actuator is trained to have a curved or flexed shape in its austenite phase. As such, the manipulator is operated, such that when one SMA actuator is heated and takes on its “trained” shape in the austenite phase, the other SMA actuator is permitted to cool and allowed to return to its original “untrained” shape in the martensite phase, and vice versa. This antagonistic operation of the SMA actuators allows the manipulator to achieve rapid flexion and extension movements.

Abstract: An apparatus that can operate with electronic ballasts (10) for electric discharge lamps to drive dc-powered lighting equipment (26) is provided. The apparatus is directly connected to the output of the electronic ballast (10) and is then used to control the power being supplied to the dc-powered lighting equipment (26). The maximum power delivered to the dc-powered lighting equipment (26) is substantially equal to the rated output power of the electronic ballast (10). A switching converter is acted as the necessary input impedance for the electronic ballast (10). Thus, the active power and reactive power drawn from the electronic ballast (10) can be controlled. The output of the switching converter provides dc power for the dc-powered lighting equipment (26).

Abstract: A diffractive optical waveguide for optical pupil expansion and a display device are provided. The diffractive optical waveguide comprises a waveguide substrate and a grating structure. The grating structure is disposed on a surface of the waveguide substrate or in the waveguide substrate and comprises a plurality of periodic structures arranged at intervals along a first direction and arranged at intervals along a second direction. The second direction is different from the first direction. A first distance between the centers of adjacent periodic structures in the first direction is smaller than a second distance between the centers of adjacent periodic structures in the second direction. The grating structure is equivalent to a one-dimensional grating with a grating vector in a vertical direction of the first direction, and the vertical direction is parallel to a plane where the grating structure is located.

Abstract: In one or more embodiments, the present invention provides am method of making a poly(propylene fumarate-co-succinate) (PPFS) copolymer containing a random incorporation of succinate groups and targetable reduction profiles without the need for three or more monomer units. To achieve this, a time-dependent sonication-promoted zinc/acetic acid reduction of the PPM unsaturated double bonds has been used to create a random PPMS copolymer which may be isomerized into the PPFS equivalent. By changing the sonication time as well as the ratios of acetic acid, zinc, and PPM unsaturated alkenes, partial reduction of the PPM alkenes has been shown to give PPMS products containing varying compositions of succinic and maleate units, which may then be isomerized to the PPFS product.
