A spatial location system capable of spatially locating a device in three dimensions is described comprising at least three of: a transmitter and a receiver, together with an antenna array operably connected to each, wherein each antenna array is capable of varying a pointing angle of at least one antenna lobe independently without the need to move either the antenna array or its constituent parts physically and wherein at least three antenna lobes are arranged such that they may partially intersect at one or more pointing angles under electronic control. The antenna array may, for example, comprise at least a first sub-array and at least a second sub-array wherein the second sub-array is oriented substantially orthogonally to the first sub-array and at least a third sub-array wherein third sub-array is positioned at a location which is not coincident with the location at which the at least a first sub-array is positioned.

The pointing angle of an antenna lobe or null or other characteristic feature of the antenna radiation pattern of a first sub-array and the pointing angle of an antenna lobe or null or other characteristic feature of the antenna radiation pattern of at least a second sub-array together with the pointing angle of an antenna lobe or null or other characteristic feature of the antenna radiation pattern of at least a third sub-array may be independently controllable in order to allow each to separately locate a signal which falls within their respective steering ranges. A point within the area of intersection of the three or more beams, when they are arranged to point at a signal to be located, may be reported to a further process or system as a three-dimensional spatial location of the signal source or its transmitting antenna.

Disclosed are examples of systems, apparatus, methods and computer program products for locating unmanned aerial vehicles (UAVs). A region of airspace may be scanned with two scanning apparatuses. Each scanning apparatus may include one or more directional Radio Frequency (RF) antennae. The two scanning apparatuses may have different locations. Radio frequency signals emitted by a UAV can be received at each of the two scanning apparatuses. The received radio frequency signals can be processed to determine a first location of the UAV.

A device including an antenna and a control method thereof are provided. In the method, a base station receives, from at least one terminal, a reference signal transmitted through at least one beam based on beam sweeping. Also, the base station calculates an angle between the base station and the at least one terminal transmitting the reference signal by using the received reference signal for each beam, and computes an optimal antenna orientation of a base station antenna of the base station by using the calculated angle. Further, the base station adjusts an orientation of the base station antenna according to the optimal antenna orientation of the base station antenna.

A golf ball with embedded electronics to allow proximity to be tracked and to monitor golfer performance is disclosed. The golf ball comprises a processor connected to an accelerometer, communications circuitry, a spin detector, and memory, wherein the processor stores accelerometer data from the accelerometer and rotation data regarding rotation of the spin detector in the memory. The processor converts the data regarding the rotation of the spin detector into a rotation speed and a rotation direction, said rotation speed determined by a frequency of the data, and said rotation direction determined by a magnitude of the data. The communications circuitry is configured to communicate the accelerometer data, the rotation direction, and the rotation speed to a central interrogator for analysis of a golfer's performance.

Systems, apparatuses, and methods are described for operating and maintaining a data network, and for detecting problems such as signal leakage. In one implementation, a computing device may determine, based on availability and location, one or more mobile devices and may cause the mobile devices to detect a wireless signal. The detected wireless signal may be identified as having leaked from a network, such as a wired network, and used to detect the source of leaks.

Systems and techniques are provided for indoor positioning for mobile devices. An orientation of a mobile device may be determined. An angle of a line-of-sight between the mobile device and the base station may be determined based on a peak received signal strength of a signal from the base station at a beamforming antenna of the mobile device. A distance between the mobile device and the base station may be determined based on the peak received signal strength. The mobile device may calculate the location of the mobile device using the measured orientation, the angle of the line-of-sight, and the distance between the mobile device and the base station, and a location of the base station.
