Abstract:
A vehicle interior mirror system comprises a housing adapted for releasable mounting to a receiving structure on the interior surface of the windshield of a vehicle. A first electrical component/accessory preferably is included in the housing. A rearview mirror comprising a rearview mirror element attaches to the housing by a pivot joint, the rearview mirror being pivotally adjustable about the housing and the housing remaining fixedly mounted to the interior surface of the windshield of the vehicle while the rearview mirror is being adjusted. The rearview mirror includes a second electrical component/accessory. A removable cover on the housing provides access to at least the first electrical component/accessory in the housing. Preferably, electrical wiring passes through the pivot joint, while the rearview mirror is an electro-optic mirror. Various electrical components/accessories can be housed in the housing that attaches to the windshield, such as a rain sensor, a compass sensor, a headlamp sensor, an antenna, a camera, a microphone, or the like.
Abstract:
An optical module includes a lens housing and a substrate having a base and a sidewall. An image sensor is mounted to the base. The sidewall includes a joint surface and the lens housing includes a mounting surface. The mounting surface of the lens housing is bonded to the joint surface of the substrate thus mounting the lens housing to the sidewall. To minimize the overall width of the optical module and to maximize the strength of the bond between the lens housing and the substrate, the mounting surface of the lens housing is formed with a locking feature. The locking feature includes a horizontal surface bonded to the joint surface and a vertical surface bonded to an interior surface of the sidewall.
Abstract:
A light detection equipment in a component with at least one optical access includes a light conveyor having a first terminal part faced inside the component through an optical access. The first terminal part is formed by a spherical cap collecting the light arriving from any angle inside the component. The light conveyor has a second terminal part with a surface faced and substantially in contact with a sensitive element of an optical transducer.
Abstract:

Abstract:
A method and apparatus for protecting a bolometer antenna imaging array from out of band electromagnetic energy is disclosed. Protective pads are disposed upon a window in an optical system forming a millimeter wave image on an array of bolometer antenna sensors. The protective pads are effectively opaque to infrared and visible emissions and are aligned to shade the bolometer portion of the bolometer antennas from infrared and visible emissions, while leaving the antenna portion of each sensor in the array exposed to intercept the millimeter wave energy incident upon them.
Abstract:
A method of encapsulating a phototransducer comprises mounting the phototransducer on a substrate, depositing a surfactant on the substrate, and depositing an encapsulant on the substrate over the surfactant. The surfactant alters a surface tension of the substrate. The encapsulant forms a protective structure that protects the phototransducer.
Abstract:
The flat display screen for an image-forming tube consists of a front pane portion (2,2′) and a circumferential flange portion (3,3′). The flange portion has an outer surface with a circumferential solder edge (7,7′) on an end of the circumferential flange portion (3,3′) on an opposite side from the front pane portion (2,2′). The outer surface has a circumferential ring-shaped region (5,5′), designated a KC surface, which extends substantially parallel to a central axis (8,8′), which is perpendicular to a surface of the front pane portion (2,2′) passing through a center point on the front pane portion (2,2′). So that the flange portion height can be reduced without increasing the danger of implosion, the wall thickness of the circumferential flange portion (3,3′) of the outer surface between the solder edge (7,7) and the circumferential ring-shaped region (5,5′) is greater than a wall thickness of the circumferential flange portion in the circumferential ring-shaped region (5,5′). In a preferred embodiment the solder edge (7,7′) has a width that is less than the wall thickness of the flange portion (3,3′) between said solder edge (7,7′) and the circumferential ring-shaped region (5,5′). A pressing tool (10,10′) for making the display screen is also described.
Abstract:
A highly reliable optical add/drop device is described. The optical add/drop device has an external tube and a ring, wherein the external tube and the ring are made of metallic material. A WDM filter is fixed in the ring. The ring is inserted in the external tube at the middle portion and fixed therein by soft solder technique. A single fiber collimator and a dual fiber collimator are respectively coupled with the opposite surfaces of the filter, and aligned in the external tube. Additionally, the single and dual fiber collimators are also fixed therein by soft solder technique, as two metal tubes respectively hold the single and dual fiber collimators. In the invention, the WDM filter is rigidly fixed to avoid tilting during temperature variation. Moreover, the invention provides an optical add/drop device with low insertion loss and reflection loss.
Abstract:
This invention relates to a fluorescent lamp with a discharge vessel enclosing a discharge path and containing a gas fill. The gas fill may be by excited by a discharge arc. The discharge vessel has at least two sections located adjacent to each other. There are bypass means for providing a bypass path for the gas discharge during a startup of the lamp between the two adjacent sections of the discharge vessel. The bypass path results in a short-cut across the impedance of a portion of the discharge path. A method for starting a discharge arc of the fluorescent lamp is also disclosed. In the method, a voltage is applied between two electrodes across the discharge path, and a bypass path is provided between two ends of a bypassed part of the discharge path. The discharge path is divided into a bypassed part and a remaining part. The combined impedance of the bypass path and the associated bypassed part is selected to be lower than the impedance of the associated bypassed part, and thereby a relatively increased voltage is provided across the remaining part. The gas fill is excited in the remaining part of the discharge path with the help of the increased voltage. Thereafter the impedance of the remaining part is lowered and the voltage across the bypassed part is increased. Finally, the gas fill is excited in the bypassed part by the relatively increased voltage across the bypassed part.
