A sun visor comprises a sun visor body (2) and a vanity mirror assembly (1) comprising a vanity mirror (11) mounted on a support (12). The sun visor comprises a first set of clips (31, 32) configured for snap-fit connection of the vanity mirror assembly (1) onto the sun visor body (2) so that the vanity mirror assembly (1) is held firmly against the sun visor body (2) by the first set of clips, and a second set of clips (41, 42; 51, 52) configured for snap-fit connection of the vanity mirror assembly (1) onto the sun visor body (2) allowing for movement of the vanity mirror assembly (1) in relation to the sun visor body (2). If the snap-fit connection by the first set of clips fails after an impact, the vanity mirror assembly may remain attached to the sun visor body by the second set of clips.

A deployable measurement system for analyzing a rail of a railroad track includes a housing, a reflecting assembly coupled to the housing, a movement assembly coupled to the housing, and an optical measurement system disposed within the housing. Both the housing and the reflecting assembly are moveable between a stored position and a deployed position. The movement assembly includes a deployment assembly that moves the reflecting assembly from the stored position to the deployed position, and a retraction assembly that moves the reflecting assembly from the deployed position to the stored position. The optical measurement system emits and receives light. The reflecting assembly reflects the emitted light toward the rail. The reflecting assembly reflects light reflected off of the rail toward the optical measurement system. The light received by the optical measurement system is used to measure parameters related to the rail.

The optic inlay comprises a coupling portion, and the spherically mounted retroreflector comprises a coupling element arranged between the optic inlay and the carrier.

A telescope that includes a hollow body, an optical system and mirror positioned in the hollow body,—a device for adjusting tilt and the position of the mirror including a carriage translatably movable in the hollow body, a mirror support plate rigidly connected to the carriage by a hinge, where the carriage is translated by a screw/nut mechanism operated by an adjustment button mounted capable of rotating in a housing portion, the adjustment button is arranged such that rotation of the button causes the carriage to be translatably moved, the adjustment button is associated with a stop member designed to cooperate with a complementary stop member arranged in the housing portion so as to limit button rotation and carriage movement, and at least one actuator movably mounted in the carriage that on the support plate such that moving the actuator changes the tilt of the plate.

An adjustable optical arrangement includes an optics mount, an optical element held at the optics mount, a holding structure having a ball joint for receiving the optics mount, a ball joint holding the optics mount at the holding structure, a first adjustment device configured to pivot the optics mount with respect to the holding structure about a first axis, and a second adjustment device configured to pivot the optics mount with respect to the holding structure about a second axis. The ball joint is disposed between the optical element and the first and the second adjustment device.

Disclosed are timepieces including a first mirror that is at least partially transparent and a second mirror. The second mirror is coupled to the first mirror to articulate with respect to the first mirror about a first axis. A time display is coupled to the second mirror. Also disclosed are reflecting devices including a first mirror and an articulating device coupled to the first mirror. A rotatable device is coupled to the articulating device and a second mirror is also coupled to the rotatable device. Additionally disclosed are reflecting kits including a mirror and an articulating device coupled to the mirror. A ring is coupled to the articulating device. The ring has an aperture. A reflective material is configured to be received by the ring. Methods of using these devices and kits are also disclosed.

Disclosed is a novel assembly and method that enables a user to collimate a focused Cassegrain telescope. The assembly, having a secondary mirror and support baffle, comprising an axle, a bearing, and hub, enables a user to precisely rotate or freely spin a Cassegrain telescope's secondary mirror about its optical axis. Incident to freely spinning the telescope's secondary mirror, the user may peer into the telescope's eyepiece and observe a focused image that may wobble, or remain stable, dependent upon how well the telescope's mirrors are aligned. Further, the assembly's eyepiece, comprising a reticle design, enables the observer to measure the magnitude and direction of image shift incident to the secondary mirror spinning. Lastly, the assembly, comprising a radially marked collimating faceplate, and radially marked collimating knob screws, enables a user to make specific adjustments to the telescope's secondary mirror, compensating for the observed image shift, precisely collimating the telescope.

A deployable measurement system for analyzing a rail of a railroad track includes a housing, a reflecting assembly coupled to the housing, a movement assembly coupled to the housing, and an optical measurement system disposed within the housing. Both the housing and the reflecting assembly are moveable between a stored position and a deployed position. The movement assembly includes a deployment assembly that moves the reflecting assembly from the stored position to the deployed position, and a retraction assembly that moves the reflecting assembly from the deployed position to the stored position. The optical measurement system emits and receives light. The reflecting assembly reflects the emitted light toward the rail. The reflecting assembly reflects light reflected off of the rail toward the optical measurement system. The light received by the optical measurement system is used to measure parameters related to the rail.

In certain embodiments, a gimbal assembly includes an enclosure, a window, and a pivot assembly. The enclosure is centered on a first axis and the window is coupled to the enclosure. The pivot assembly is coupled to an interior portion of the enclosure and configured to pivot within the enclosure about a second axis, the second axis being perpendicular to the first axis. The pivot assembly includes a base portion, a mirror coupled at an angle to the base portion and configured to reflect light received through the window, and a sensor configured to receive the light reflected by the mirror. The pivot assembly is further configured to move within the enclosure in a direction that is perpendicular to the first axis and rotate about the first axis.

Infant observation mirror assembly with temperature display for attachment to a top portion of a rear vehicle seat includes a main panel having opposed front and rear surfaces and a mirror embedded in the front surface thereof. The mirror assembly further includes a temperature display section defined on the front surface of the main panel. A positioning base is coupled to the rear surface of the main panel. The main panel is pivotably attached to the positioning base for allowing rotation about a horizontal axis and a vertical axis. A mounting harness attaches to the positioning base. The mounting harness removably attaches to the top portion of the rear vehicle seat to hold the mirror assembly in a selected lateral and vertical position on the rear vehicle seat.
