Abstract: A microphone assembly includes one or more transducers (2210) that are positioned in one or more housings. A preprocessing circuit (2215) includes a inverted comb filter (2245) for eliminating predetermined frequencies between harmonics of the human voice in a predetermined frequency range. A processing circuit (2220) coupled to the preprocessing circuit (2215) is used for outputting an electrical signal such that the transducers (2210) used in combination with the processing circuit (2220) very effectively cancels noise. The microphone assembly can be employed in a vehicle accessory such as a vehicular mirror.
Abstract: A visor assembly for an aviation helmet includes a lens, lens/strap anti-tear interface assemblies, retainer plates, and attachment strap assemblies. A friction strip mounted on the brim of the helmet operates to increase the friction between the visor lens and the helmet. The combined function of the friction strip and the configuration of the strap assemblies operate to maintain the visor in a deployed (as-worn) positioned in front of the wearer's face, even during high speed wind blasts of up to 600 KEAS (Knots Equivalent Air Speed).
Abstract: The present invention relates to improved imaging devices having high dynamic range and to monitoring and automatic control systems incorporating the improved imaging devices.
Abstract: An autobias vehicular microphone system (300) includes a microphone (301) which uses an amplifier (306) for amplifying an output of the microphone. A first feedback path (308) provides an amplifier output signal to the amplifier input for providing amplifier linearity, and a second feedback path (305) is used for providing bias to a voltage reference (303). The voltage reference (303) operates to provide an autobias to the amplifier (306) based upon amplifier load-ing. By holding the bias point to a constant voltage, a constant clip level can be maintained depending on varying load conditions of electronic devices (307, 309, 311) using the microphone (301). Additionally, one or more switches can be used to vary the bias point which can be interpreted to control functionality of the electronic devices (307, 309, 311).
Abstract: Electro-optic elements are becoming commonplace in a number of vehicular and architectural applications.

Abstract: An exterior light control system for controlling exterior lights of a controlled vehicle is provided, which includes an imager configured to image a scene external and forward of the controlled vehicle and to generate image data corresponding to the acquired images. A controller is configured to receive and analyze the image data and generate a control signal for controlling the exterior lights of the controlled vehicle. The controller is further configured to receive temperature information relating to an operational temperature of the imager, wherein when the controller determines that the operational temperature of the imager is below a temperature threshold, the control signal includes an indication that the imager is blocked.
Abstract: A rearview device having a rearview display. A rearview device attachment assembly is connected with the rearview display and includes a mount and an attachment clip coupled to the mount. The attachment clip includes a base and first and second opposing flex members extending from the base, each including an arcuate flex portion extending from the base. A connecting portion extends from the arcuate flex portion at an angle toward the base. An engagement portion extends away from the connecting portion at an angle away from the base. First and second protrusions project from the mount, each extending through first and second slots, respectively, in the base. The first and second protrusions are in abutting contact with the engagement portion of the first and second opposing flex members, respectively, thereby forcing the first and second opposing flex members at least partially away from the base.

Abstract: A method and system are provided to image an external scene by employing a custom image sensor. The custom image sensor may use a GRRB array to filter the images of oncoming and preceding vehicle taillights captured by a vehicle camera. The method and system may also calculate a GRRB color metric for use in the custom image sensor by performing interpolation on a number of color channels, summing the brightness values for each of the color channels interpolated, normalizing each of the brightness values, and converting the normalized brightness values from an RGB scale to a linear scale of non-red to red.
