  • Patent number: 9625907
    Abstract: Systems and methods for controlling an unmanned aerial vehicle within an environment are provided. In one aspect, a system comprises one or more sensors carried on the unmanned aerial vehicle and configured to receive sensor data of the environment and one or more processors. The one or more processors may be individually or collectively configured to: determine, based on the sensor data, an environmental complexity factor representative of an obstacle density for the environment; determine, based on the environmental complexity factor, one or more operating rules for the unmanned aerial vehicle; receive a signal indicating a desired movement of the unmanned aerial vehicle; and cause the unmanned aerial vehicle to move in accordance with the signal while complying with the one or more operating rules.

  • Publication number: 20120271377
    Abstract: Embodiments of the disclosed technology provide a combination electroencephalography and non-invasive stimulation devices. Upon measuring an electrical anomaly in a region of a brain, various tDCS or other electrical stimulations are utilized to correct neural activity. Devices of the disclosed technology may utilize visual, balance, auditory, and other stimuli to test the subject, analyze necessary brain stimulations, and administer stimulation to the brain.

  • Patent number: 6904835
    Abstract: Disclosed is a coupler that grips the internal surface of a torque receptor such as a pipe or driveshaft to be turned. When torque is applied to the coupler, one or more gripping surfaces are forced apart by a cam mechanism. The gripping surfaces tightly engage the internal surface of the pipe in response to movement of an internal cam. Torque applied to the wrench causes the pipe to turn. Because the wrench grips the internal diameter of a torque receptor, it can be used without damaging the external surface of the torque receptor, and used in very confined spaces. The gripping surfaces distribute the gripping load evenly across the pipe, which minimizes any deformation of the pipe.

The gripping surfaces distribute the gripping load evenly across the pipe, which minimizes any deformation of the pipe. The pipe is engaged by the gripping surfaces beyond the threaded portion of the pipe, where the pipe has more structure, to prevent ovaling.
