Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for a magnetic MEMS apparatus that in some instances may comprise a magnetic circuit and a MEMS device. The magnetic circuit may include two magnets that may be disposed on the substantially flat base and magnetized vertically to the base and in opposite directions to each other to produce a substantially horizontal magnetic field between the magnets. The MEMS device may comprise a mirror and a conductor to pass electric current to interact with the magnetic field created by the magnets. The MEMS device may be disposed substantially between the magnets of the magnetic circuit and above a plane formed by top surfaces of the magnets, to provide an unobstructed field of view for the mirror. The MEMS device may include a ferromagnetic layer to concentrate the magnetic field toward the conductor. Other embodiments may be described and/or claimed.

Abstract: A method for mapping includes projecting a pattern onto an object (28) via an astigmatic optical element (38) having different, respective focal lengths in different meridional planes (54, 56) of the element. An image of the pattern on the object is captured and processed so as to derive a three-dimensional (3D) map of the object responsively to the different focal lengths.

Abstract: A window is provided comprising a front pane and one or more prism units each comprising: a primary prism disposed adjacent the front pane and having a primary entrance face and a primary exit face. The primary entrance face is configured to receive a first and a second portion of light that passes through the front pane. The window further comprises a secondary prism disposed adjacent the primary prism and having a secondary entrance face and a secondary exit face. The secondary entrance face is configured to receive from the primary exit face at least the second portion of light. At least one of the entrance and exit faces comprises a light diverging surface which causes divergence of light passing therethrough, and at least one of the entrance and exit faces different from the light diverging face, comprises a light converging surface configured to reduce the divergence.
