20100085257 | SYSTEM AND METHODS FOR DIRECTION FINDING USING A HANDHELD DEVICE - A system for indicating the relative direction of a target object or location as determined from the current position of a wireless communication device. The system employs Direction of Arrival determination using an antenna array for indicating the direction of a target device and includes facilities to activate a location-indicating transmission in a target device, the ability to request that a location-indicating transmission be activated in a remote target device, relevant information reception from a target device and the display of all potential target devices within effective transmission range of the wireless communication device. | 04-08-2010 |
20130113659 | DETECTION OF SIGNALS - Described herein is a method and apparatus for the detection of signals in an area of interest. Three sensor channels are provided for sensing radiated emissions in an area of interest, each channel having a sensor and a processor, the three channels sensing radiated emissions in the very low frequency band, the high/very high frequency band, and the ultra high frequency band respectively. The first and third sensor channels provide input signals to the processor in the second sensor channel so that accumulated signal data can be processed to produce an input signal for a comparator. The comparator compares the input signal with data stored in a database to indicate presence of equipment having known modes of operation. | 05-09-2013 |

20140152505 | APPARATUS AND METHOD FOR ESTIMATING DIRECTION OF RADIO FREQUENCY SIGNAL - An apparatus and method for estimating the direction of an RF signal is provided. The apparatus includes an antenna for receiving an RF signal. An electronic compass is configured to, as a pointing direction of the antenna is varied, generate information about pointing directions and pointing angles corresponding to variations in the pointing direction of the antenna. A control unit determines RSSI values at respective, pointing angles of the antenna based on a received signal of the antenna and information of the electronic compass depending on the variations, extracts a maximum RSSI value from the RSSI values at respective pointing angles, and stores the maximum RSSI value and a pointing direction corresponding to the maximum RSSI value. A display unit displays the RSSI values at the respective pointing angles and a trajectory of the RSSI values at respective pointing angles under control of the control unit. | 06-05-2014 |
20150331081 | AN APPARATUS AND METHOD TO PROVIDE A USER WITH AN INDICATION OF A DIRECTION TO A PARTICULAR DESTINATION - An apparatus configured to receive, from a remote apparatus (master navigator), a bearing signal indicating the directional offset of a destination with respect to a directional reference, and use the bearing signal to indicate, on a portable apparatus (direction resolver), the heading of the destination with respect to a directional reference of the portable apparatus. Also discussed are a method, computer program code, and a bearing signal. | 11-19-2015 |
