Abstract: A bicycle spoke reflector system that is easily attached to the individual spokes of a bicycle tire assembly is disclosed. The tubular spoke reflector members possess a reflective exterior surface and a longitudinal split to facilitate attachment to the spokes of the bicycle wheel. The tubular spoke reflector member is attached to the bicycle tire spokes by elastically spreading apart the longitudinal split in the spoke reflector member, by aligning the tubular member longitudinal split with the bicycle spoke and applying pressure to the side of the tubular member opposite the split. This allows insertion over and placement of the tubular member onto the individual spokes, relying on the elastic properties of the tubular member material to close around the bicycle spoke, and remain attached.

Abstract: An optical switching system is disclosed which can achieve high speed optical switching with a simple configuration. Light from a light irradiation section is irradiated into an optical transmission line made of a material having a nonlinear optical effect and disposed on the upstream side with respect to an optical switch provided for performing switching of a transmission line to cause the nonlinear optical effect to occur. Thereupon, light is emitted externally from the optical transmission line by the nonlinear optical effect between the light irradiated by the light irradiation section and light propagating in the optical transmission line. The light emitted is received by a light reception section to acquire intensity information of the light propagating in the optical transmission line. The intensity information is used as driving signal for driving the optical switch.

Abstract: A device that will enhance the signature of a target by utilizing retrorective articles and can operate in an "active" or "passive" mode. The device consists of a sphere on which a number of corner cube reflectors are mounted. The sphere is then mounted on top of the target and, in the "active mode", is rotated around its vertical axis. The sphere is then illuminated by a laser and the reflected energy is received by an appropriate electro-optical sensor, such as an image intensifier or a FLIR. In the "passive" mode, the sphere is either rotated around its horizontal axis, or remains stationary, and the reflected ambient radiation is received by an appropriate sensor.

Abstract: A spoke mounted bicycle reflector having first, second, and third reflective members. The first reflective member has two, generally parallel, reflective faces. The second and third reflective members have two, generally parallel, faces but only one face of each is reflective. The second and third reflective members extend outward from the first reflective member so that the faces of the second and third reflective members are in a substantially perpendicular orientation to the faces of the first reflective member, and so that the longitudinal axis of each is aligned with the longitudinal axis of the first reflective member. The mount of outward extension of the second and third reflective members can be fixed or slidably adjustable in position in relation to the first reflective member. The first and second reflective members produce a mono-directional flashing effect when the wheel is rotated in the presence of a light source.
