Abstract: An unmanned aerial vehicle (UAV) navigation system includes a portable, ground-based landing pad comprising having a first antenna configured to transmit a data packet; a UAV comprising a second antenna configured to receive the data packet; and second processing circuitry configured to determine a signal strength between the first antenna and the second antenna; determine, based on the signal strength, an orientation of the vehicle relative to the landing pad; and determine, based on a time of flight of the data packet, a distance between the vehicle and the landing pad.

Abstract: A method, apparatus, and electronic device for displaying data are disclosed. A non-rectangular addressable liquid crystal display 402 with a non-rectangular active area active matrix 334 may display an adjustable presentation of data. A display-integrated control key may control the presentation of data. A scrolling navigation control may scroll through the adjustable presentation of the data.

Abstract: A document storage device having a cover and a layer of material coupled to the cover. The cover and the layer of material together define a pocket assembly configured to receive an indicator sheet. The pocket assembly includes a window configured to permit viewing of at least a portion of the indicator sheet through the otherwise generally opaque pocket assembly. The window extends substantially to an edge of the cover.

Abstract: The present invention is directed to a laser system for use in combination with a golf club. This laser system enables first and second beams of light to be projected therefrom to assist a golfer in setting up for a golf shot, aiming a golf shot, diagnosing one or more frailties in the golfer's swing, and/or increasing a level of consistency of the golfer's swing from one swing to the next. Indeed, these first and second light beams from the laser system may be utilized to provide information to enable one to discern if the golfer's swing deviates from an initial shaft plane of the golf club.
