Abstract: Some embodiments comprise apparatuses providing an electrical conductor guide for use with an irrigation device comprising: a housing having a volume and containing an electronic component and one or more electrical conductors coupled thereto; a support structure having one or more apertures each configured to allow at least one of the one or more electrical conductors to extend therethrough; and a potting material at least partially filling and sealing the volume from an external environment, wherein the one or more electrical conductors extend out of the potting material and the housing; wherein the support structure is cooperated with the one or more electrical conductors and is configured to inhibit movement of the one or more electrical conductors relative to the potting material due to external forces applied to the one or more electrical conductors to reduce the forces applied to the potting material or to electronic component.

Abstract: A display apparatus includes an image source that scans about two axes. To offset motion about a first of the axes during sweeps about the second axis, the apparatus includes a structure to produce offsetting motion about the first axis at a scanning rate equal to the twice-scanning rate about the second axis. The offsetting scan can be a ramp or other motion. In one embodiment, the offsetting motion is a resonant sinusoid. The offsetting motion may be produced by an auxiliary scanner such as a mechanical scanner, a piezoelectric scanner, a MEMs scanner or other scanner. Because the offsetting motion is very small, the auxiliary scanner can function with a very small scan angle.
