Abstract: An apparatus, with moving parts, having a flexible circuit configured such that its fatigue life is enhanced. The apparatus includes a first component, a second component, and a positioning mechanism between the first component and the second component. The positioning mechanism enables movement of the first component and the second component between at least a proximate position and a spaced-apart position. Also included between the first component and the second component is a flexible circuit that has a first end coupled to the first component and a second end coupled to the second component. The flexible circuit is configured as a compliant spring that can extend and collapse in a predefined shape when the components are spaced-apart and proximate, respectively.

Abstract: A compact mounting for a wave plate permits convenient rotational adjustment of the wave plate through an angle of at least one-half revolution to exploit asymmetry in the optical characteristics of the wave plate.

Abstract: A projection display system. The projection system includes a light source, illumination optics that are capable of splitting the light from the source into individual color bands, and folding mirrors. The folding mirrors operate to direct the color bands to a reflective element that has a contoured surface. The contoured surface of the reflective element causes the light to form into scanning rasters that are recombined and sent to a spatial light modulator. The spatial light modulator is typically made up of a panel of individually addressable elements. If the spatial light modulator requires polarized light, a polarizing beam splitter and quarter-wave plate are included as part of the illumination optics.

Abstract: A single port antenna connector assembly, mateable with either a retractable antenna or a hardline connector, is provided. When the antenna connector is mated with the connector assembly, it engages a signal contact supplying an antenna signal. When the hardline connector is mated, it engages a signal contact supplying a conductive signal to test equipment, or to an auxiliary antenna. The signal contacts have different positions in the assembly, with each connector being differentiated to engage only its corresponding signal contact. In addition, the design of connector assembly permits the antenna to be withdrawn through the connector assembly, at least partially, past the unused test signal contact. The antenna has at least two positions so that the profile of the antenna can be reduced for either storage, or for lower gain operation when the device is in a standby mode of operation.
