  • Patent number: 11995157
    Abstract: An intelligent three dimensional scanner system mountable on a movable machine, including three dimensional scanner, a camera, and control circuitry. The control circuitry is configured to receive three dimensional point data from the three dimensional scanner, receive two dimensional image data from the camera, input the two dimensional image data to a machine learning model, which identifies objects in the two dimensional image data, fuse the three dimensional point data with the identified objects in the two dimensional image data in order to identify the objects in the three dimensional point data, and control a scan pattern to direct scanning resolution of the three dimensional scanner based on the identified objects.

  • Publication number: 20130002027
    Abstract: An uninterruptible power supply includes an input and an output. The uninterruptible power supply may include a first power path between the input and the output. The uninterruptible power supply may also include a second power path between the input and the output. The second power path may include a rectifier and an inverter. The uninterruptible power supply may also include controls configured to operate the uninterruptible power supply to supply electricity to the output. In controlling the uninterruptible power supply, the controls may selectively operate in first mode by transmitting electricity from the inlet to the outlet via the first power path while operating the inverter to condition at least one characteristic of electricity at the output. The controls may also selectively operate the uninterruptible power supply in a second mode by transmitting electricity from the input to the output via the second power path.

  • Patent number: 7994798
    Abstract: A method of testing power converter current sensors is disclosed. The method may include receiving a current sensor test request and receiving measured currents from current measurements from the at least one current sensor, based on the test request. The method may further include comparing the measured current of the sensor with a stored profile and determining whether a fault exists in each current sensor being tested. The method may also include providing a user with a test report.

  • Publication number: 20090189444
    Abstract: A power supply system for supplying power to a load is disclosed. The power supply system includes a power source, a high voltage terminal coupled to the power source, a programmable controller coupled to the power source, and a first low voltage terminal and a second low voltage terminal. Each low voltage terminal is coupled to the programmable controller. The programmable controller may be programmed to switch each of the first and second low voltage terminals between a connected state and a disconnected state and to implement a power up strategy when initially supplying power to the load.

  • Patent number: 7511449
    Abstract: A system is provided for controlling an electric machine. The system has a power source configured to supply electric energy to the electric machine. In addition, the system has an inverter operationally connected to the power source and the electric machine and configured to increase or decrease a rotor flux component of a voltage applied to the electric machine, while maintaining a torque component at an essentially constant level. The system further has a control device configured to determine at least one parameter of the electric machine and operate the inverter in either a first or a second mode in response to the at least one determined parameter.
