The most common modern spudger is a black or yellow nylon stick with a metal hook at one end. Various versions have blunt, sharpened, or insulated hooks. The hook can be used for pulling bridge clips from 66 blocks, manipulating wires in a crowded wire wrap block, or setting DIP switches. The body of a plastic spudger is usually contoured to ...
This works at a wide range of angle of incidence, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence. Being directed, the retroflector's reflection is brighter than that of a diffuse reflector. Corner reflectors and cat's eye reflectors are the most used kinds.
One popular style is the star anchor, an anchor plate cast or wrought in the shape of a five-pointed star. Other names and styles of anchor plate include earthquake washer, triangular washer, S-iron, and T-head. [2] In the United Kingdom, pattress plate is the term for circular restraints, [3] tie bar being an alternative term for rectangular ...
An antenna reflector is a device that reflects electromagnetic waves. Antenna reflectors can exist as a standalone device for redirecting radio frequency (RF) energy, or can be integrated as part of an antenna assembly.
A corner reflector is a retroreflector consisting of three mutually perpendicular, intersecting flat reflective surfaces. It reflects waves incident from any direction directly towards the source, but translated .
A key feature of the cat's eye is the flexible rubber dome which is occasionally deformed by the passage of traffic. A fixed rubber wiper cleans the surface of the reflectors as they sink below the surface of the road [2] (the base tends to hold water after a shower of rain, making this process even more efficient). The rubber dome is protected ...
A bicycle reflector or prism reflector is a common safety device found on the rear, front and wheels of bicycles. It uses the principle of retroreflection to alert another road user of the bicycle's presence on the road. The reflector is usually manufactured in the form of a moulded tile of transparent plastic.
The surface of this type of vibrating coating line is distributed and scattered with raised bumps. Some bumps are coated with high-refractive-index glass beads.When a speeding vehicle runs over the raised road lines, it produces a strong warning vibration to remind the car driver of deviation from the lane.
