Abstract: The presence of eyeglasses worn by a human subject is detected regardless of whether the subject's head is viewed frontally or in profile. Image data within search windows defined relative to the subject's eye is processed to form linear representations of edge boundaries. Angles formed by intersections of the linear representations are determined and used as a basis for determining if eyeglass lenses are present. When prescribed eyeglass components are detected, the eye detection and tracking routines are configured accordingly.

Abstract: An antenna-receiver communications system and method is provided to mechanize multibeam mobile antenna-receive subsystems. Digital beam forming for modern wideband mobile communications systems is provided. In an aspect, subsystems can simultaneously receive, acquire, track and output a multiplicity of signals from sources of different locations using a single antenna aperture from a mobile platform. The angle of arrival of a signal of interest is continuously determined. Individual phased array antenna output channels are phased aligned as required by the phased array equation and monopulse signal processing. Angle sensing and beamsteering are separated from antenna channel coherent summation. Thus, the angle sensing and beamsteering functions are not required to be computed at the data rate, but can instead be computed at a rate necessary for the beam acquisition and beam tracking function speed requirements. Signal processing computational load and system cost is reduced as compared to current systems.

Abstract: A mat seal device for preventing water from entering an electrical connector through an opening provided for cables to be inserted into the connector. The device includes an elastic mat that plugs an opening in the connector. A peripheral edge seal of the mat seals between the mat and an inner surface of the connector housing.

Each cable insertion hole includes annular sealing ribs that elastically enlarge when receiving a cable and seal against an outer surface of the cable. Recesses formed in front and back surfaces of the mat adjacent the cable insertion holes relieve expansion of the sealing ribs.

An actuator selectively displaces the striker plate between its end limits of travel in response to a control signal. Finally, an interlock fixes the striker plate in the cinched position in the absence of the control signal.
