  • Publication number: 20160128168
    Abstract: Wirelessly networked network light device(s) and method for operating and/or controlling the network light device(s). The network light device can be connected to a network, and be controlled by a controller connected to one or more sensors. The operation of the network light device, such as a color of the light emitted, etc., can be controlled by the controller based on conditions detected by the one or more sensors.

  • Patent number: 8590330
    Abstract: A method of operating a transport refrigeration unit that is operable to regulate a temperature of a cargo space. The method includes providing a controller, driving a refrigerant compressor of the transport refrigeration unit with an internal combustion engine to compress a refrigerant defining an engine operating state of the transport refrigeration unit, and driving the refrigerant compressor of the transport refrigeration unit with an electric motor to compress the refrigerant defining a motor operating state of the transport refrigeration unit. The method further includes sensing the temperature of the cargo space, receiving into the controller a signal indicative of the temperature of the cargo space, determining the temperature of the cargo space using the controller, and switching between the engine operating state and the motor operating state in response to a signal generated by the controller based on the temperature of the cargo space.

  • Publication number: 20120265429
    Abstract: A system for determining a fuel consumption of a transportable environmental-control unit. The system includes a sensor and a controller. The sensor is configured to sense an amount of fuel in a tank. The controller is configured to receive an indication of the amount of fuel in the tank from the sensor, monitor and filter the indication of the amount of fuel received from the sensor for a first period of time, monitor and filter the indication of the amount of fuel received from the sensor for a second period of time, and determine a quantity of fuel used between an end of the first period of time and an end of the second period of time.

  • Patent number: 8286437
    Abstract: A transport unit including a container defining a cargo space. The transport unit includes position detection apparatus coupled to the container, and adapted to determine a geographic location of the container and to generate a signal indicative of the geographic location. The transport unit also includes a refrigeration system in communication with the cargo space, and a control system including route data that defines a plurality of potential destinations of the container. The control system is programmed to predict a container route defined by at least two potential destinations of the container based on the geographic location and the route data, and to determine a proximity of the container relative to at least one potential destination of the route. The control system is in communication with the refrigeration system to control the refrigeration system based on the proximity of the container relative to the at least one potential destination.

  • Publication number: 20110291828
    Abstract: A communication system for a climate-controlled container. The system includes a controller and a radio expansion module removably connected to the controller. The controller is coupled to the refrigerated container and configured to monitor a status of the refrigerated container. The radio expansion module is configured to support a communication mode, and to communicate the status to a remote system. The communication mode used to communicate with the remote system is determined by the controller based on the communication modes supported by the radio expansion module.

  • Patent number: 4683469
    Abstract: A display terminal adapted to present character information, in any one of a plurality of different display formats, within a display frame having approximately constant dimensions. The terminal preferably includes a programmable CRT controller, first and second character memories, horizontal and vertical deflection circuits for selectably generating output signals having first or second periods, a central processor and circuitry for generating constant frequency dot clock and character clock signals. In establishing each display format, the central processor programs the CRT controller with the display parameters that are appropriate for that format and generates a plurality of display format control signals for controlling the selection of a character memory and the periods of the output signals of the horizontal and vertical deflection circuits.
