20110057848 | Antenna apparatus and methods of use therefor - Antenna apparatus and methods of using the same that employ a broadband, planar, single feed ultra high frequency satellite communication (UHF SATCOM) antenna device which may be mounted on composite or other non-metallic and non-electrically conductive surfaces. The antenna apparatus may be implemented using a single antenna feed and impedance matching network with a low profile antenna shape that optimizes over-the-horizon gain, with no requirement for a ground plane. The antenna apparatus may also be implemented to cover the entire UHF SATCOM frequency band using a single antenna feed. | 03-10-2011 |
20130154887 | ANTENNA TESTING ENCLOSURES AND METHODS FOR TESTING ANTENNA SYSTEMS THEREWITH - Antenna enclosure apparatus are provided that may be used to verify the signal path integrity, amplitude and/or phase of a single antenna or multiple antennas of direction finding (DF) antenna array and associated electronics without interference of external signals such as ground interference signals present when an aircraft-based antenna is tested on the ground. An individual antenna test enclosure may in one embodiment be provided as an antenna hood having a cavity dimensioned for internally receiving an antenna, such as an aircraft external blade antenna. The cavity of the antenna enclosure may be lined with a RF absorbing material inside the enclosure to allow for RF path testing with substantially no “ringing”, so that accurate phase and gain testing of a received antenna and its RF signal path may be accomplished. | 06-20-2013 |

20080297922 | MOBILE LENS UNIT WITH DETECTION DEVICE - A lens unit including a lens barrel for receiving at least one lens, a motor arranged to displace the lens barrel between an initial position and a maximum displacement, wherein the displacement of a lens barrel is proportional to the level of an electrical signal applied to the motor when the electrical signal is between first and second levels, the first level corresponding to a level for starting movement of the lens barrel from the initial position and the second level corresponding to a level for bringing the lens barrel to the maximum displacement; a first conductor fixed to the lens barrel and arranged to make electrical contact with a second conductor when said lens barrel is at one of said initial position and said maximum displacement; and a processor arranged to detect a change in the contact situation between the first and second conductive surfaces, to determine one of said first and second levels based on level of the electrical signal at the time of the change and to generate, based on said determined level, a level of said electrical signal for a desired displacement. | 12-04-2008 |
20090102403 | VCM CONTROL CIRCUIT - A method of controlling a moving part of a voice coil motor to move from an first position to a second position, wherein the position of the moving part is controlled by the level of an electrical signal applied to a coil of the voice coil motor, a first level of the electrical signal corresponding to the first position, and a second level of the electrical signal corresponding to the second position, the method including: at a first time, changing the electrical signal from the first level to an intermediate level, the intermediate level being chosen such that a peak overshoot of the moving part corresponds to the second position; and at a second time calculated to correspond to a delay of half an oscillation period of the moving part after the first time, changing the electrical signal to the second level. | 04-23-2009 |
20130155239 | IMAGE SENSOR WITH IMPROVED DYNAMIC RANGE - An image sensor having improved dynamic range includes a signal that is read out for a selection of pixels which act as a calibration to govern the choice of exposure levels to be applied to the rest of the array. In this way, the sensor is operable to adapt to variations in scene intensity. The pixels in the array are vertically and horizontally addressed so as to enable accounted for small areas of intensity variation across an imaged scene. | 06-20-2013 |

20090008730 | Integrated optical filter - The disclosure relates to an integrated circuit comprising at least one photosensitive cell. The cell includes a photosensitive element, an input face associated with the said photosensitive element, an optical filter situated in at least one optical path leading to the photosensitive element and an interconnection part situated between the photosensitive element and the input face. The optical filter is disposed between the photosensitive element and the surface of the interconnection part closest to the input face. In particular, the optical filter can be disposed within the interconnection part. The disclosure also proposes that the filter be formed using a glass comprising cerium sulphide or at least one metal oxide. | 01-08-2009 |
