Abstract: A Littrow-type spectrometer or monochromator using a folded light path to provide a compact optical instrument is disclosed. Light enters the instrument through an inlet aperture on a planar mirror. The aperture is located at the focus of a parabolic collimator mirror. Collimated light reflected by the parabolic mirror is reflected back to the planar mirror, which is positioned at an angle to the collimated light. The light reflected from the planar mirror is directed at a planar grating that produces diffracted light having all the wavelengths input into the system, including light of a selected wavelength, back towards the planar mirror. Light having the selected wavelength is thus caused to fall on the parabolic mirror. The parabolic mirror then focuses the selected wavelength of light onto a light exit aperture that is juxtaposed to the inlet light aperture. The planar grating can be rotatably mounted to scan the input light spectrum.

Abstract: A mobile radio receiver system for a vehicle providing recent segment replay function is disclosed. The wireless receiver is adapted to be contained within the vehicle. A digital delay line is coupled to receive the output of the wireless receiver. A delay selection switch is coupled to the digital delay line to route the output of the wireless receiver with a selected temporal delay in response to actuation by a person riding in the vehicle. In accordance with the preferred embodiment, the recent transmitted segment ends at the time that the delay selection switch is actuated. A control device is associated with the wireless receiver for receiving control selections from the person riding in the vehicle. An amplifier is coupled to receive the routed output of the wireless receiver. An audio transducer this adapted to receive the output of the amplifier and provide an audible signal to the person riding in the vehicle.
