Publication number: 20240077587Abstract: A receiver for a lidar system. The receiver comprises a monolithic block of optically transmissive material, the block shaped to define a planar light receiving surface, a first reflective surface and a second reflective surface positioned adjacent to the light receiving surface. The surfaces are positioned such that light from a distant on-axis source passing through the light receiving surface passes through the block to the first reflective surface and is reflected thereby towards the second reflective surface and in turn reflected thereby to pass through a receiving aperture formed in the first reflective surface and to come to a focus at or after the receiving aperture.Type: ApplicationFiled: December 3, 2021Publication date: March 7, 2024Inventors: Tom JELLICOE, Alex CONEY, Neil GRIFFIN

Patent number: 8464771Abstract: A multi-layer laminate media is provided on which information may be applied in machine or human readable form on a visible front surface by the output of one or more lasers, or other high intensity light source. In a preferred embodiment, the media has three layers including preferably transparent substrate, a thermochromic layer and a light absorbent layer located intermediate the media substrate and the thermochromic layer. The light absorbent layer is adapted to absorb light from the light source and convert the absorbed light into heat. The heat is immediately conducted into selected portions of the thermochromic layer which is in thermal contact with the light absorbent layer, causing portions of the thermochromic layer to change visual appearance such as color to create the desired mark. The media optimally includes obscuration materials to reduce the visibility of the light absorbent layer to the naked eye.Type: GrantFiled: November 12, 2010Date of Patent: June 18, 2013Assignee: Sinclair Systems International LLCInventors: M.
