摘要： A vehicular frameless interior rearview mirror assembly includes a mirror head and a mounting portion. The mirror head includes a mirror reflective element and a mirror casing. The mirror reflective element includes a glass substrate having a planar front side and a planar rear side. No portion of the mirror casing overlaps the planar front side of the glass substrate of the mirror reflective element. A camera is disposed within the mirror casing behind the mirror reflective element. With the mounting portion of the mirror assembly mounted at an in-cabin side of a windshield of a vehicle, the camera views a driver of the vehicle, and when the mirror head is moved by the driver to adjust a rearward view of the driver, the camera moves in tandem with movement of the mirror head. The camera is part of a driver monitoring system of the vehicle.

摘要： A vehicular interior rearview mirror assembly includes a mounting structure, a plastic mirror casing, and a mirror reflective element having a glass substrate. The glass substrate includes a periphery surface extending between a planar first surface and a planar second surface and spanning a thickness dimension of the glass substrate. The mirror casing includes a central mounting portion and spaced apart attachment portions. The mirror reflective element is adhesively attached the spaced apart attachment portions. The central mounting portion includes a first pivot element and the mounting structure includes a second pivot element, the first pivot element and the second pivot element forming a pivot joint. The periphery surface of the glass substrate includes a curved outer surface that provides a rounded transition between the planar first surface of the glass substrate and a less-curved outer surface of a side wall of the mirror casing.

摘要： Disclosed is an apparatus and method for processing eyeglass lens which determines the completion of the eyeglass lens processing by using a hall sensor. The eyeglass lens processing apparatus comprises: a grinding wheel mounted frame (22) mounted with a grinding wheel (20) for grinding a lens, and whose position is changed according to a predetermined grinding depth of the lens; a carriage (12) for moving the lens to contact with the grinding wheel (20), and which contacts with the grinding wheel mounted frame (22) when the lens which contacts with the grinding wheel (20) is grinded to the predetermined grinding depth; and a hall sensor detector (30) for detecting a contact of the grinding wheel mounted frame (22) and the carriage (12), wherein the hall sensor detector (30) includes a magnet (32) and a hall sensor (34) for detecting an intensity of a magnetic field generated by the magnet (32), the magnet (32) is equipped on either one of the carriage (12) and the grinding wheel mounted frame (22), and the hall sensor (34) is equipped on the other one of the carriage (12) and the grinding wheel mounted frame (22), in case an output signal of the hall sensor (34) is “A” when the grinding wheel mounted frame (22) and the carriage (12) are in contacts with each other, if the output signal of the hall sensor (34) is smaller or larger than “A” by a tolerance, it is determined that the grinding wheel mounted frame (22) and the carriage (12) are in a separated state.

摘要： A method and device for milling a large-diameter aspheric surface by using a splicing method and a polishing method to solve the problems of large time consumption and serious tool wear in the machining of a meter-scale large-diameter aspheric surface are disclosed. where an aspheric surface is discretized into a series of rings with different radii, and the rings are sequentially machined via generating cutting by using an annular grinding wheel tool with an outer diameter less than ¼ of a diameter of the aspheric surface; the rings are equally spaced, there are a total of N rings, and a width of any ring is jointly determined by the Nth ring, the (N−1)th ring, positioning accuracy and a generatrix equation of the aspheric surface; and the aspheric surface is enveloped by a large number of rings. A contact area between the tool and a workpiece surface is rings.

摘要： A mirror device includes a multi-phase substrate and a single-phase layer. The multi-phase layer is formed of reaction-bonded silicon-carbide (RB-SiC, or Si/SiC) material. The single-phase layer is formed of elemental silicon. The single-phase layer is formed in-situ, that is, contemporaneously with, the formation of RB-SiC material. The single-phase layer is integrally bonded, as one piece, to silicon of the multi-phase substrate. Methods of making a multi-layer device, such as a mirror device, are also described. One such method includes providing a porous mass of silicon carbide and carbon, causing molten elemental silicon to infiltrate the porous mass to form RB-SiC material, simultaneously causing the silicon to flow into a cavity to form a single-phase layer of polishable silicon, integrally bonding silicon in the cavity to the RB-SiC material, and, if desired, polishing a surface of the single-phase layer.

摘要： A device for processing spectacle lenses has a work chamber, which is accessible by way of an opening and in which a workpiece mount and at least one tool mount are opposite one another and movable relative to one another so that a processing region of a tool held at the tool mount can be brought into processing engagement with a workpiece held at the workpiece mount and in processing engagement can be guided over the workpiece. For recognition of wear at the tool, a sensor equipment with at least one contactlessly operating sensor arrangement is provided and is movable outside the work chamber between a protected rest position and a detecting position. In the detecting position the sensor equipment is constructed to detect at the processing region of the tool held at the tool mount an unacceptable deviation beyond a predetermined amount from a desired geometry.

摘要： Methods and systems for manufacturing a wavefront-guided scleral lens prosthetic device customized for an eye of a patient include obtaining a first scleral lens prosthetic device with a central optic zone configured to vault over the eye's cornea and a peripheral haptic zone configured to align with the eye's sclera, collecting measurements of any offset and/or rotation of the first scleral lens prosthetic device relative to the eye's pupil and of any aberrations, particularly higher-order aberrations, generating a wavefront-guided profile from the measurements, and fabricating a second scleral lens prosthetic device with the profile on a surface of a central optic zone configured to vault over the eye's cornea and a peripheral haptic zone customized to align with the eye's sclera.
