Abstract: An optical pattern projection device includes a light emitter or light emitter array and one or more flat optics layers configured to project and split light beams from the light emitters to generate a projected light pattern including multiple sub-patterns each corresponding to one of the light emitters. The flat optics layers may include a single optical metasurface containing superposed beam shaping and/or projection phase profile and a beam splitting phase profile. Alternatively, the flat optics layers may include two optical metasurfaces each containing a light shaping and/or projection phase profile, which together produce a linear relationship between light emitter position and corresponding beam projection angle, and one or both of the metasurfaces further contains a superposed beam splitting phase profile. The light shaping and/or projection phase profile may have a function similar to a micro-lens array. A structured light camera combining optical pattern projection and detection is also provided.

Abstract: An information input device includes: a communication interface configured to communicate with each of a first external apparatus that operates using a first operating system and a second external apparatus that operates using a second operating system; and a controller configured to operate in a first mode corresponding to a first driver used by the first external apparatus when transferring data to the first external apparatus, and operate in a second mode corresponding to a second driver different from the first driver and used by the second external apparatus when transferring data to the second external apparatus.

Abstract: The present invention discloses a Fe—Al-based metal membrane and preparation method thereof, which relate to the technical field concerning gas-solid separation under high-temperature, low-pressure working conditions, and mainly address the defects of conventional metal filter elements in the prior art such as high filtration resistance and low flux under low-pressure working environments. The preparation method of the present invention comprises the steps of: stirring and defoaming a mixture composed of a Fe—Al-based metal powder and an organic-additive-added water-based solvent, thus obtaining a cast slurry; casting a uniform membrane layer on a metal substrate layer having a required thickness on a casting machine, and performing drying treatment on it, thus obtaining a membrane green body; and, placing the dried membrane green body in a sintering furnace for degreasing, sintering, and alloy phase ordering treatments, respectively, thus obtain a prepared Fe—Al-based metal membrane.

Abstract: A hitting apparatus is provided, including a supporting unit, at least a linking unit, and an attaching device. The apparatus includes foldable supporting legs, an adjustable supporting rod, an adjustable hanging arm, an adjustable extension arm, connection elements, attaching elements and attaching ball. The adjustable extension arm is flexible, which can be adjusted at any direction by hand, or foreign force. The connections between connection elements are detachable and releasable upon hit by bat or other subjects. The hanging arm is engaged to the top of supporting rod, and adjustable in length and angles and easy to be detached from the support rod to become a hand held hitting training apparatus. The attaching parts of hook/loop, magnets, adhesive or rubbers holding the ball with minimum detaching releasable force required, The present invention can enhance the focus of the batter on the ball and have a clear hit on the ball.

Abstract: The invention relates to graftable polymers comprising biologically active agents and the use of such polymers in the manufacture of shaped articles, such as implantable medical devices and catheters. The graftable polymers are covalently grafted to a surface via one or more grafting moieties incorporated into the pharmaceutically-active graftable polymer. The coated articles of the invention can further comprise tie-coats, and the ratio of polymer:tie coat can be used to adjust the rate of drug elution.

Abstract: A hitting apparatus is provided, including a supporting unit, at least a linking unit, and an attaching device. The apparatus includes foldable supporting legs, an adjustable supporting rod, an adjustable hanging arm, an adjustable extension arm, attaching rods or strings, and attaching ball hook/loop, magnets or adhesives. The hanging arm is engaged to the top of supporting rod, and adjustable in length and angles and easy to be detached from the support rod to become an individual hitting training apparatus. The attaching parts of hook/loop, magnets or adhesive hold the ball with attaching loop or metal tape or coating. With the holding of the ball by the hook/loop, magnet or adhesives, the present invention can be a tee free design to enhance the focus of the batter on the ball and have a clear hit on the ball. The present invention is easy to assemble, adjust, use, carry around and store.

Abstract: A printable, pressure-sensitive adhesive ("PSA") tape, particularly a self-wound tape, which comprises a polyester film substrate, a rubber base prime coat and an adhesive which can be fire-retardant. The PSA tape has high adhesive properties and a novel release mechanism which does not use any conventional release agents.
