Abstract: A method for detecting a source of interference creates a sorting table according to distances between station devices and an access point (AP) device, and the created sorting table is sent to the AP device. The AP device determines upon a target device from the sorting table and controls the target device to acquire status and distance information between target device and AP device and send the information to the AP device. A value ε is computed according to the information sent by the target device and the calculated value ε is compared with a preset value k. The source of an interference, which affects the signal sent by the AP device, is calculated based on the comparison, and the AP device applies appropriate de-noising to the signal according to the determined interference source.

Abstract: A social alarm system provides location detection within a dwelling. A personal radio trigger unit is carried by a client and transmits an alarm signal in response to a triggering event, such as by a manual alarm button or an automatic fall detection circuit. A client unit is operable to receive the alarm signal and initiate an alarm call to a remote monitoring center over a communications network. A plurality of radio receptor nodes monitor the wireless RF transmissions from the personal radio trigger to report respective received signal strength values. A location finder unit determines a location of the personal radio trigger, by using absolute error calculations and/or shape error calculations against previously recorded known locations in the dwelling.

Abstract: The invention relates to adjusting at least one of installed building service sensors (10) of a building service system. A sensor coverage area of at least one sensor (10) is adjusted based on information on a position of the installed sensor (10) relative to at least one other sensor (10). For example, to determine the position of the sensor (10) relative to said at least one other sensor (10), each sensor (10) establishes a wireless communication between said sensor (10) and at least one other sensor (10) via a wireless communication means (34) of the sensor (10). For example, information on the positions of the installed sensors (10) is used to assign to each sensor (10) at least one of installed building service supply devices (12) of the system.

Abstract: A geo-fence capable device is disclosed that is capable of performing an accurate geo-fence operation while minimizing power consumption. The device includes sensors, Wi-Fi connectability and GNSS. Sensors intermittently detect whether the device is in motion. When determined to be in motion, Wi-Fi is used to acquire a wireless access point list and to compare the access point list to previously-stored access points in order to determine whether the device is still within a particular region. GNSS is used to confirm exit from a region and to intermittently monitor whether the device has entered a new region. GNSS and application processor use can be minimized by utilizing sensor and Wi-Fi functionality as preliminary region monitors.

Abstract: A method of determining room occupancy of a room in a facility having an indoor positioning system with wireless access point fingerprints each correlated to a location in the facility. The method may include receiving a request from a computing device for a room occupancy assessment associated with the room. It may further include obtaining location data that correlates to the location of one or more people from the indoor positioning system and determining from the location data associated with the room whether the room is occupied. The determination of whether the room is occupied is then sent to the computing device.

Abstract: This specification allows a plurality of terminals to exchange and use data stored in each of the terminals through their own embedded web servers. An information providing system according to embodiments disclosed herein includes a first web server and a first controller both embedded in a telematics terminal mounted in a vehicle, and a second web server and a second controller both embedded in a mobile terminal. The first controller requests the second web server to transmit a first data corresponding to a first user request, receives the first data from the second web server, and executes the received first data. The second controller requests the first web server to transmit a second data corresponding to a second user request, receives the second data from the first web server, and executes the received second data.
