A beam combiner includes a first beam-input face, a beam-output face, and first and second reflectors. The first beam-input face receives first and second beams of electromagnetic energy respectively having a first and second wavelengths. The first reflector reflects the first received beam toward the beam-output face, and the second reflector passes the first beam from the first reflector and reflects the received second beam toward the beam-output face. In one alternative, the first beam-input face also receives a third beam of electromagnetic energy having a third wavelength, the beam combiner includes a third reflector that reflects the received third beam toward the beam-output face, and the first and second reflectors pass the third beam from the third reflector. In another alternative, the beam combiner includes a second beam-input face that receives a third beam directed toward the beam-output face, and the first and second reflectors pass the third beam.

In at least some embodiments, a filter comprises a filtering media. The filtering media is impregnated with chemical compounds that effectively retain water molecules and water-alcohol molecules but not alcohol molecules. The filter also comprises a liquid channeling structure, wherein the liquid channeling structure directs liquid entering an input of the filter to flow through the filtering media before exiting an output of the filter.

A multi-standard connection hub includes a housing (110) having a first surface (111), a second surface (112) spaced apart from the first surface, and a sidewall (113) extending between the first surface and the second surface. The multi-standard connection hub further includes a first connection port (120) at the first surface and a second connection (210) port at the sidewall. The first connection port operates according to a first standard and the second connection port operates according to a second standard.
摘要:
A scan assembly of an image generator sweeps an image beam in a first dimension at a first rate and bi-directionally in a second dimension at a slower rate. Sweeping the beam bi-directionally in the vertical dimension (generally the dimension of the lower sweep rate) can reduce the scanning power by eliminating the flyback period, and, where the scan assembly includes a mechanical reflector, can reduce the error in the beam position without a feedback loop by reducing the number of harmonics in the vertical sweep function. Furthermore, because the image beam is “on” longer due to the elimination of the flyback period, the scanned image is often brighter for a given beam intensity. The scan assembly may also sweep the image beam non-linearly in the vertical dimension, and this sweep may be bi-directional or uni-directional. Sweeping the beam non-linearly can also reduce the error in the beam position by reducing the number of harmonics in the vertical sweep function.
