A light guide for an LED luminaire includes a light receiving surface, a concave first surface, a second surface, and an extraction surface. The concave first surface is positioned to receive a first light portion of incident light. A best-fit plane of this first surface is angled between 6° and 48° relative to an axis perpendicular to the light receiving surface, reflecting the first light portion via total internal reflection downstream. The second surface is downstream and offset from the first surface, allowing a second light portion to bypass the first surface. The second surface reflects this second light portion to create a virtual image of the light source outside the guide. The extraction surface is configured to extract both the first and second light portions, enabling controlled distribution of direct and indirect light while minimizing color separation and imaging artifacts.

The invention concerns an apparatus (10) for transporting elongated articles (200), comprising a conveying device (11) and a plurality of carriers (20) associated with said conveying device (11) such as to advance along a transport direction (A), each carrier (20) comprising a pair of gripping and orienting members (22, 23), one (22) of which is motorized, each configured to grip an elongated article (200) at a respective end thereof. The gripping and orienting members (22, 23) are positioned in front of each other and rotatable about a same rotation axis (R) which is positioned orthogonally to the transport direction (A), and when the elongated article (200) is gripped by the gripping and orienting members (22, 23), its longitudinal axis (L1) coincides with the rotation axis (R).

A flight data analysis system for birds comprises a recording device (10) and a processing device (20). The recording device (10) is detachably mounted on a bird to compute and store multiple flapping values (S1) of the bird in a flight. The processing device (20) is electrically connected with the recording device (10) to receive the multiple flapping values (S1) and determines multiple motion states of the bird in the flight according to the multiple flapping values (S1).

A processing method of heat transfer printing fabric based on UV-printed three-dimensional graphics, relating to a field of fabric printing technology. The processing method includes the following steps: applying hot-melt adhesive onto a release layer, drying and preparing a hot-melt adhesive layer; performing UV inkjet printing on the hot-melt adhesive layer to form graphics, and laminating a protective layer onto the surface of the hot-melt adhesive layer to obtain a hot-melt adhesive layer with graphics; and removing the release layer from the hot-melt adhesive layer with graphics, spreading the hot-melt adhesive layer onto a fabric, pressing at a temperature of 140-160 °C, removing the protective layer and obtaining printed fabric with three-dimensional graphics.

The present invention relates to the field of lighting technology, specifically to a reflector assembly using a multi-light-source for changing illumination effect, comprising a reflector cup, a first light source and a plurality of second light sources; the first light source and the second light sources are independently controlled from each other; the plurality of the second light sources are arranged around the first light source, the reflector cup has a light inlet and a light outlet; and the first light source and the second light sources are located in the light inlet; a reflective curved surface for reflecting light rays emitted by the first light source and the second light sources is formed at an inner wall surface of the reflector cup; when the first light source and the second light sources are turned on simultaneously, the light rays emitted by the first light source forms a first light spot through the light outlet, and the light rays emitted by the second light sources forms a second light spot through the light outlet; an interval region is formed between the first light spot and the second light spot, and a microstructured reflective part for reflecting part of the light rays emitted by the first light source or/and the second light sources towards the interval region is formed on the reflective curved surface along circumference of the reflective curved surface. Since microstructured reflective part is provided, the effect of improving the aesthetics of the light spot is achieved.

An apparatus and method of controlling a repetitive motion linear actuator (RMLA) accepts a minimum repetition rate and a commanded repetition rate. If the commanded rate is greater than the minimum rate, the RMLA automatically operates in a speed scaling mode by continuously applying the cycles and scaling the cycle length to provide the commanded rate. If the commanded rate is less than the minimum rate, the RMLA automatically operates in a dwell mode by fixing the cycle length and discontinuously applying the cycles, while adjusting a separation between the cycles to provide the commanded rate. In dwell mode, the cycle length can be equal to its maximum allowed value T<max>, or can equal a desired value less than T<max>. The cycle can have any profile shape, such as a sinusoidal shape or a shape that includes periods of deceleration and acceleration separated by constant speed periods therebetween.

The present invention concerns a composition for producing a building product, as well as a method for obtaining it, wherein an inert part and a binding part are provided. The composition is dry, that is, in the form of granulate or powder.
