Abstract: A light fixture includes an optics assembly, a frame assembly, a reflector, and a diffuser. The optics assembly includes at least one light source for emitting light in a first direction. The diffuser is formed from a pliable material. The frame assembly is adapted to support the reflector and the diffuser relative to the optics assembly such that the reflector reflects light emitted by the at least one light source toward the diffuser.

Abstract: A light fixture having a light engine with at least one light source and a shade formed of a light transmissive, pliable material adapted to diffuse light emitted from the at least one light source outwardly from the light fixture. In some embodiments, the light transmissive, pliable material is a fabric material.

Abstract: A non-glare luminaire includes a toroidal-shaped light engine having light emitting diodes (LEDs) disposed about the light engine in a radial pattern. The light engine has an axial direction that is at least substantially orthogonal to the surface of the light engine. An anti-glare ring is disposed proximate the light engine and includes reflectors arranged in a radial pattern. Each reflector is configured to reflect tangentially oriented light from at least one of the LEDs substantially along the axial direction. The luminaire also includes a toroidal integrated optic (TIO), which is made up of a total internal reflectance (TIR) lens that is coupled with a light guide. The TIO optic has a toroidal lens portion having a light entrance side that receives light from the LEDs and the reflectors. The optic collimates the light received from the LEDs and the reflectors and emit the light via a light exit side.

Abstract: A neck exercise machine including a frame, a seat, a set of pulleys, a head band, an adjustable tensioner, and a cable adjustably attached to the head band, threaded through the pulleys, and removably connected to the adjustable tensioner, such that when a user sits in the seat and attaches the head band, they can exercise their neck muscles in a variety of different angles, rotations, and tensions. Elastic bands, an analog/digital force gauge, or hydraulic cylinder may be used as the adjustable tensioner and incorporate processor, memory, and data output mechanisms for performance analyses. The machine can also be broken down into numerous parts for easy transport and reassembly.

Abstract: A container or package filled with perishable food materials is closed by a cover presenting a vent hole and the assembly is subjected to sterilization or pasteurization. Thereafter the vent hole is closed by means of a hot melt having a melting point lower than the highest temperature during sterilization or pasteurization. Preferably the hot melt is applied before sterilization or pasteurization and provided with a perforation joining the vent hole. The hot melt may contain a rounded rigid body not melting at the highest sterilization or pasteurization temperature and being able to seal the vent hole, such as a glass bead.After cooling the closed container is under a subatmospheric pressure.The container may be of plastics or glass and the cover may be of plastics or plastic coated metal foil, in such a case the plastic coating has a melting point being higher than the melting point of the hot melt.
