Abstract: An intelligent traffic control system may be configured to manage autonomous vehicle traffic, such as by communicating with autonomous vehicles. The intelligent traffic control system may be configured to output an indication of a traffic control command to autonomous vehicles and non-autonomous vehicles. The intelligent traffic control system may be configured to determine traffic control commands for autonomous vehicles and non-autonomous vehicles.

Abstract: Systems and methods regarding distributed energy resource systems (DERs) are described. Configurations and employed methods may include sending a command to a DER system to place the DER system in one or more of a charge state, a discharge state, an idle state, or a reactive power state. These DER systems may include an energy storage circuit, a dc/ac converter configured to receive a DC voltage from the storage circuit and convert the received DC voltage for receipt by an external AC circuit, and one or more controllers configured to designate operation state of the storage circuit in at least a charge state, a discharge state, and an idle state.

Abstract: A distributed energy resource (DER) may store electrical power from an AC circuit and discharge stored electrical power to the AC circuit. A DER may be coupled to the AC circuit via a plug inserted into a receptacle coupled to the AC circuit, and a load device may be plugged into the DER via a receptacle of the DER. The DER may pass AC power from the AC circuit to the load device, and may draw additional power from the AC circuit to charge an energy storage circuit of the DER. The DER may also discharge stored energy into the AC circuit and/or power the load device directly.

Abstract: A control system is provided for positioning between a power source, such as a distributed generator, and a utility or utility grid to control the injection of dc current and even harmonics into the utility or utility grid. In one embodiment, the control system is particularly suited for grid-tied operation and includes a power converter for acting as an ac current source by converting power received from the power source to ac current for transmittal to the utility. The control system further includes a voltage transformer between the power converter and the utility connection to block dc current and isolate the power source from the utility. A feedback control loop is included in the control system to measure, with a pair of current transformers, dc current and even harmonics in the current flowing into (power converter side) and out (utility side) of the voltage transformer.

Abstract: A system for delivering power to a battery and to a load includes a power source that supplies energy to the battery and the load. The battery can be charged by the power source and used to supply energy or power to the load when the power source is unable to provide sufficient energy and power to the load. The system reduces injection of DC current into the load and, as a result, extends the operation life of the load, particularly if the load is an AC lighting or lamp system. The system operates the load in an optimal manner such that battery storage is maintained at near full charge, yet the lighting load operates for a maximum number of hours per night. The benefit of the system is to prevent early failure of either the lighting load or the battery.

Abstract: A system for transforming coordinate systems in an automated video monitor alignment system includes a camera and computer to capture an image of the display bezel surrounding the cathode ray tube and of the image displayed on the CRT. Three dimensional models of the CRT tube and display bezel are used to compute and compensate for camera perspective. Camera pixel data can then be transformed to `flat plane` coordinates. When the relative orientation of the camera and CRT are corrected for, the effects of parallax can be eliminated, allowing more accurate inspection, measurement, and lower cost fixturing on the production line. Thus, an accurate coordinate transformation from a camera-referenced coordinate system to a monitor-referenced coordinate system is made.
