  • Publication number: 20210306546
    Abstract: A method for assessing an ambient light level during video acquisition with a video camera is provided. The video camera is operably connected with an IR illuminator, and having a day mode in which an IR-cut filter is arranged in front of an image sensor and a night mode in which the IR-cut filter is not arranged in front of the image sensor. The method comprises: acquiring a stream of images with the video camera in night mode, with the IR illuminator having a first illumination output level, and then reducing an output level of the IR illuminator to a predetermined illumination output level during acquisition of a sequence of a predetermined number of consecutive image frames within the image stream, and then assessing a measure representative of an ambient light level from an evaluation of the sequence of image frames.

  • Patent number: 11082624
    Abstract: A video camera system comprises an imaging system having a camera lens and an image sensor, and a retractable IR-cut filter, and a control unit for controlling the imaging system. The video camera system has a day-mode in which the IR-cut filter is arranged in front of the image sensor, and a night-mode in which the IR-cut filter is retracted from its position in front of the image sensor. Furthermore, the video camera has a field of view defined by properties of its imaging system, and it comprises a separate light-sensor for measuring an ambient light level so as to support a decision regarding when to actuate a transfer from night-mode to day-mode, or vice versa. The camera system is characterized in that the separate light sensor has imaging optics and is enabled for a variable field of view, which is aligned with a field of view of the video camera system, and in that a current field of view of the video camera system is used when selecting an active field of view of the separate light sensor.

  • Publication number: 20200090532
    Abstract: This invention relates to a control system at an airport and a method implemented in such a control system. The system comprising: an input unit being arranged to communicate with an airport surveillance system at an airport, a control unit being arranged to receive, from the input unit, identification data for an aircraft on ground, position data, indicating a position of the aircraft, and, to provide the identification data to a data storage and receive an identifier of a designated gate for the aircraft from the data storage, wherein the control unit is further arranged to provide a signal to a gate control system at the designated gate for preparing the designated gate to receive the aircraft if the position of the aircraft is within a predetermined distance from the designated gate.

  • Patent number: 8145285
    Abstract: Gaskets and wireless terminals with gaskets for sealing a space between sliding members in wireless terminals. The wireless terminals include: (a) a first member; (b) a second member overlying the first member, wherein at least one of the first and second members is configured to slide between open and closed configurations; and (c) a gasket attached to the first and second members, the gasket having an elongate body portion with opposing first and second end portions affixed to a respective one of the first and second members. The gasket is configured to provide an electrical path between at least one component in the first member to at least one component in the second member. The elongate body portion is configured to snugly abut the first and second members to inhibit dust from entering a target interior space when the wireless terminal is in the open configuration.
