In one example, the lens includes a curved prismatic surface that can be oriented toward or away from the underlying light source.

The invention discloses a pressure-control type electric pressure cooker. A sealed body is formed by sequentially connecting a pot cover, a seal ring, an inner pot and an outer pot; a plurality of belleville springs, which are provided with opening grooves, are arranged between a heating plate and the outer pot; upper supporting rings are formed by horizontally flanging the small-diameter ends of the belleville springs towards inner sides, and lower supporting rings are formed by the big-diameter ends of the belleville springs; an elastic deformation area is formed by a conical wall parts between each of the upper supporting rings and each of the lower supporting rings; the elastic deformation areas penetrate through the upper supporting rings in a radial direction and extend to conical body parts, and the opening grooves that contour lines projected on a horizontal plane are in a cross form are formed; the opening grooves are of gradually expanded structures with upsides smaller than downsides from openings to bottoms; the lower supporting rings are supported on the bottom of the outer pot; the upper supporting rings are propped against supporting legs of the heating plate; and the supporting legs and the belleville springs are integrally positioned with and connected to the outer pot by virtue of fixed screws. The amount of elastic deformation of the electric pressure cooker is effectively improved by virtue of the belleville springs, and the change in induction pressure of a pressure detection device is more conveniently to be detected, so that the precision and the safety stability of pressure control are improved.

A structure for a high diffuse efficiency and water-proof lighting device is provided, including a light tube and a base holder. The light tube and the base holder are each an enclosed structure. The light tube includes a circuit substrate inside the enclosed structure. The circuit substrate includes a plurality of LEDs. The light tube and the base holder each include two holes close to both ends.

A water-proof and highly pull-resistant glue is used to fill the overlapping of the holes. A resilient element is used to connect the neighboring circuit substrates, the resilient element can absorb the deformation caused by the temperature changes so that the light diffusion remains uniform. Therefore, the lighting device can perform well even when operating in an environment with drastic temperature changes.

A system providing effective, broad spectrum UV-C or other ionizing radiation clinical surface disinfection, high intensity UV-C light emitting diodes (LEDs) of incrementally differing wavelengths are sequentially embedded in densely packed reflective nacels (cups or pockets) forming the surface of a rotating spherical or hemispherical structure. A combination of UV-C emitter component location and activation with the rotational and reciprocal elevation functions of such structures produces complete and continuous environmental overlapping UV-C energy scattering.

New methodology, realizable with both manual and new semi-automatic imaging technology, has transformed both the inspection and the batch release Attribute Sampling Inspection for contaminating visible particles in injectable solutions into statistically replicable procedures. In this new non-destructive inspection procedure, a calibration curve relates NIST traceable measurement of maximum particle size to the rejection probability of the particle. Data for this calibration curve is determined with a graduated set of single durable stainless steel and glass microspheres that are sized with NIST traceability. Use of the calibration curve transforms the probabilistic variability of visible particle inspection data described by Knapp into the ‘simply replicable form’ required by the Attribute Sampling Tables. The present invention uses cutting edge imaging technology to achieve 1% sizing accuracy within 10 μm from 50 to 1,000 μm. An improved alternative sizing technique used in this invention uses the particle information to achieve an integral particle sizing function.

A light fixture or troffer for directing light emitted from a light source toward an area to be illuminated, including a reflector assembly within which the light source is positioned and a lens assembly detachably secured to a portion of the reflector assembly such that a lens of the lens assembly overlies the light source and such that substantially all of the light emitted from the light source passes through the lens assembly. The reflector assembly including at least one longitudinally extending hollow that extends inwardly to a central portion between respective first and second hollow edges. Each hollow has a plurality of longitudinally extending male ridges.

Tone mapping a high dynamic range (HDR) image is performed by obtaining a log-norm luminance component based on a normalized logarithm of the HDR image. The log-norm luminance component is flattened (tone-compressed) using incrementally-spaced adaptation levels, which are increasingly blurrier representations of the log-norm luminance component, weighted by a diminishing factor. Visual cues are restored by injecting a proportion of values of the log-norm luminance component, applying histogram tail clipping, and applying a sigmoid curve mapping, to create a restored luminance component. A tone-compressed image is obtained by mapping luminance of the HDR image using the restored luminance component and adjusting saturation of the mapped HDR image.

A light diffusion sheet comprising a transparent base material sheet; a light diffusion layer laminated on a surface of the base material sheet and containing beads dispersed within a binder; and a sticking-inhibiting layer laminated on a rear face of the base material sheet, wherein the binder of the light diffusion layer contains a thermosetting resin and the sticking-inhibiting layer is a resin layer containing an ionizing radiation curable resin. In the light diffusion sheet of the invention, which employs an ionizing radiation curable resin for the binder of the sticking-inhibiting layer, the cross-linking density of the binder can be increased, whereby the wear resistance of the sticking-inhibiting layer as well as the wear resistance of the rear face of the light diffusion sheet can be increased. Further, possible occurrence of scratches in the sticking-inhibiting layer, which is attributable to the contact between the sticking-inhibiting layer and the beads of the light diffusion layer, can be effectively avoided.

At least one light distribution device is provided in the spacing between adjacent light sources to allow light diffused from both sides of the light sources to be properly refracted and reflect so as to more evenly diffuse light toward a diffuser plate and thereby, eliminate the dark bands between adjacent light sources for effectively solving the bright bands and dark bands problem observed in prior art LCD modules.

The disclosed transducer the can transfer an audio signal into a full-spectrum tactile wave over a frequency of 10 Hz-2 KHz. Upper and lower springs of the transducer produce vibrations via a coil / magnet in a manner similar to a conventional speaker, but the transducer uses a novel arrangement of elements, such as two south-to-south coils and carbon fiber springs, so as to produce the vibrations tactilely. The transducers can be tuned for specific applications and can be attached or formed integrally with a support surface. When attached or incorporated into a chair, massage table or other human-support structure, the transducer creates a sonic environment that surrounds and permeates the body with vibration, providing a direct experience of mental desired states. When connected to any full fidelity sound system, a support structure, a full frequency response process promotes a state of relaxation in the listener.
