20130307725 | AIRBORNE SATELLITE COMMUNICATIONS SYSTEM - A system is provided to establish and maintain a data path between a Local Area Network (LAN) that is mounted on a moving vehicle and a satellite. In combination, an antenna assembly, an Antenna Control Unit (ACU), an Inertial reference Unit (IRU), and a modem are mounted together on the moving vehicle, under the overall control of a services platform. Operationally, the IRU generates parametric values indicative of the spatial attitude and location of the moving vehicle. The ACU then uses the parametric values to aim the antenna in a direction toward the satellite. In this combination, the modem is connected with the antenna to transmit and receive data between the system and the satellite. Individually or collectively, operationally compatible components of the system (IRU, ACU, antenna and modem) can be appropriately substituted to thereby customize the system. | 11-21-2013 |
20140152770 | System and Method for Wide Area Motion Imagery - A system for detecting moving objects within a predetermined geographical area is provided. The system is designed to convey object movement information from an airborne surveillance platform to a ground-based operator station with reduced data transmission. This is accomplished by computer processing image data on the surveillance platform prior to transmitting data to the ground station. First, the system constructs a 3D model of the area under surveillance, for example, by obtaining many different views of the area using an aircraft. One 3D model is maintained at the surveillance platform, and another is transmitted to the ground station. During a surveillance mission, a succession of relatively low data, 2D images are created and aligned with the surveillance platform's 3D model. The alignment reveals differences in the images (tracking data) which is then transmitted to the ground station for use with the ground station's 3D model to resolve object movement information. | 06-05-2014 |

20080246507 | Body Capacitance Electric Field Powered Device For High Voltage Lines - Devices that couple to high voltage transmission lines obtain power themselves using the body capacitance of an element of the devices. The devices generate a comparatively lower voltage from the current flowing between the high voltage line and the element of the device that generates the body capacitance. The devices can be used to operate sensors that monitor the transmission lines or parameters of the power distribution system, such as current, line temperature, vibration, and the like. The devices can also be used as indicators, such as aircraft warning lights, information signs, etc. In addition, the devices can operate as RF transmission/reception or repeater devices, radar devices, mesh networking nodes, video/audio surveillance, sound emitting devices for scaring animals, drones that traverse the power line, etc. Because the devices operate in response to line voltage rather than current, the devices are reliable even in low current conditions. | 10-09-2008 |

Methods includes monitoring a light level and voltage level and adjusting a light level, estimating power consumption, or facilitating maintenance in accordance with the light level and voltage level. The methods may be performed all or in part at a streetlight, a local gateway or a central controller and database. | 03-12-2009 |
20090066540 | Centralized route calculation for a multi-hop streetlight network - A system and various apparatus and methods performed therein configured for calculating routes touching and monitoring and controlling streetlights includes a multiplicity of streetlight controllers and a local coordinator. Each streetlight controller includes a switch operative to control the operation of a load, a sensor operative to monitor the operation of the load, a processor, and a radio transceiver operative to receive control data and transmit data associated with the streetlight controller. The local coordinator includes a coordinator radio transceiver, and a coordinator processor operative to maintain a list of the multiplicity of streetlight controllers and, cooperatively with the coordinator radio transceiver, exchange messages with any of the multiplicity of streetlight controllers. | 03-12-2009 |
20110242802 | ADAPTIVE SOLAR POWERED SYSTEM - An apparatus for powering a load from solar energy comprises logic is coupled to the converter to control its conversion rate. A detector is coupled to the converter and detects its power output. The logic is operable to adjust the conversion rate until the solar panel operates at the smaller of a maximum power point of the solar panel and a power point of the solar panel that results in a maximum desired power and second logic adjusts the energy consumption over a period of time as a function of the energy available from the solar panel over a previous same period of time. | 10-06-2011 |
20130038221 | STREETLIGHT MONITORING AND CONTROL - A system and method for streetlight control is provided. A lamp sensor inside a reflector of the streetlight is utilized to detect the output of a lamp of the streetlight. During daytime periods when the lamp is OFF, the lamp sensor is utilized to act as a day/night sensor by detecting ambient light near the lamp. When the ambient light level falls below a sufficient level indicative that night is approaching the lamp is turned ON and the lamp sensor utilized to detect the lamp output of the streetlight. | 02-14-2013 |
