  • Patent number: 10409621
    Abstract: Systems involving distributed control functions are described herein. Each member or device within the system has responsibility for controlling part of the system's behavior, and includes logic to determine what action, if any, will follow as a response to determining information or receiving information from other members or devices within the system. A change of status of one member of a system may provide a basis for action by another member of the system. Status may be the result of sensing a condition of the environment, sensing the condition of a component, receiving the output of a conventional sensor, and/or sensing the condition of a link between components. In some embodiments, action taken by a member of the system may include collecting data during law enforcement activities.

    Abstract: Example apparatus and methods acquire individual images under a variety of different operating parameters. Example apparatus and methods then piece together strips of images from the individual images. Example apparatus and methods then produce a panoramic image from the strips of images. A strip of frames is produced without using a hemispherical mirror and thus accounts more accurately for issues associated with making a two dimensional representation of a three dimensional spherical volume. Images are acquired using different imaging parameters (e.g., focal length, pan position, tilt position) under different imaging conditions (e.g., temperature, humidity, atmospheric pressure, pan rate, tilt rate). Example apparatus and methods correct images using correction data that is related to the operating parameters.

  • Patent number: 8451116
    Abstract: A wireless battery-powered daylight sensor for measuring a total light intensity in a space is operable to transmit wireless signals using a variable transmission rate that is dependent upon the total light intensity in the space. The sensor comprises a photosensitive circuit, a wireless transmitter for transmitting the wireless signals, a controller coupled to the photosensitive circuit and the wireless transmitter, and a battery for powering the photosensitive circuit, the wireless transmitter, and the controller. The photosensitive circuit is operable to generate a light intensity control signal in response to the total light intensity in the space. The controller transmits the wireless signals in response to the light intensity control signal using the variable transmission rate that is dependent upon the total light intensity in the space. The variable transmission rate may be dependent upon an amount of change of the total light intensity in the space.

  • Patent number: 8325040
    Abstract: Upon detecting (101) (via an animate object detector (506)) an animate object, these teachings provide for automatically and responsively transmitting (102) a remote light control signal and also selectively controlling (103) local lighting (505). This can comprise temporarily switching the local lighting to a higher power mode of operation (such as a fully-on mode of operation) from a lower power mode of operation (such as a fully-off mode of operation). These teachings will further accommodate determining (301) a relatively closeness of the animate object to the remote control. When the detected animate object is more than predetermined distance from the remote control, the local lighting can remain in the lower power mode of operation. When the detected animate object, however, is within that predetermined distance from the remote control, then the aforementioned step of switching the local lighting to the higher power mode of operation can be undertaken as described.

  • Patent number: 8143567
    Abstract: An occupancy sensor is provided with a separable override unit which can selectively override the operation of the occupancy sensor at designated times and for selected time intervals. The occupancy sensor includes a light sensor for actuating the occupancy sensor and a light assembly when the ambient light is below a predetermined level and to deactivate the occupancy sensor when the ambient light is above a threshold level to prevent the light assembly from being actuated when the light level is sufficient to avoid the need for actuating the light assembly.
