A sensor authentication registration system includes: sensors for detecting a state quantity of a sensing target device; and setting device that stores installation information for each of the sensors. A radio wave intensity measurement unit that measures intensity of a radio wave in wireless communication is provided to at least one of the sensors or the setting device. The setting device can perform an authentication operation to store the installation information when the presence of a sensor, the installation information of which is not stored, is detected and the radio wave intensity is equal to or higher than a threshold value. A data collection system includes: sensors; and data collection device that stores installation information for each of the sensors and receives state quantities detected by the sensors via wireless communication. In the device and a method for data collection, the state quantity is automatically received when the data collection device approaches to within a range where the wireless communication with the sensor, whose installation information is stored, can be received.

In a technique for determining a seating position of each of users in a vehicle based on wireless signals from mobile devices carried by the users, a controller identifies a position of a mobile device within a distance from a door outside the vehicle via communication between exterior communicators and the mobile devices. When receiving a signal of boarding, the controller determines whether the mobile device is present in the vehicle via communication between an interior communicator and the mobile device. When the mobile device is determined to be present in the vehicle, the controller determines that a seat corresponding to the position of the mobile device is a seating position of a user corresponding to the mobile device.

A system and method for identifying a customer's location at a business and provide notification to a company representative upon arrival of the customer at the business location. Real-time location determinations for the customer and customer location tracking can be provided. One or more wireless beacons communicate with the customer's electronic device. The beacons provide the system with real-time data about the customer's whereabouts, allowing for the confirmation and tracking of the customer at the location. A first non-limiting example of use, include a company that provides food and beverage allowing the customer to place an order for food and beverages on their electronic device and having the order delivered to the person at their current location as determined by the system. Another non-limiting example includes a company using the notification system to have assigned staff members notified of the customer's arrival.

A position estimation system includes a beacon transmitter that transmits a beacon signal, a mobile station that receives the beacon signal from the beacon transmitter and transmits positioning data including ID information of the received beacon signal, and a position information server that estimates a position of the mobile station based on the positioning data transmitted from the mobile station, in which the mobile station includes a plurality of transmission means, and switches the transmission means for transmitting the positioning data based on the received beacon signal.

This application relates to reporting and monitoring a location of a mobile device. Disclosed is an attendance recording service in which when an employee requests attendance recording using a mobile application installed in a smartphone, the smartphone communicates with a server and records clock-in and clock-out of the employee. When the employee selects an attendance recording request button from the mobile application, an analysis is made as to whether the employee is positioned in a workplace, and clock-in or clock-out of the employee is recorded only when it is determined that the employee is positioned in the workplace, thereby maintaining reliable attendance recording.

Systems and methods for a low-frequency radio navigation system are described. The system may include a transmitter comprising a base coded modulator configured to generate a base modulation and a data coded modulator configured to generate a data modulation; wherein the transmitter radiates a continuous, constant-power chirped-FM spread spectrum signal, comprising: the base modulation; and the data modulation, wherein the data modulation is orthogonal to the base modulation. The system may also include a receiver comprising a digital signal processor, wherein at least one matched filter coupled to the digital signal processor, the at least one matched filter configured to decode said base modulation and data-encoded modulation and provide a correlation function for received signals received from at least three geographically-spaced transmitters.

A narrowband localization method including: concurrently transmitting, by a plurality of transmitters, a plurality of narrowband signals, wherein frequencies of respective narrowband signals are different from each other; receiving, by a receiver, a superimposed signal of the plurality of narrowband signals; and determining, by the receiver, a location of the receiver relative to the plurality of transmitters based on the superimposed signal received by the receiver.

Head-mounted augmented reality (AR) devices can track pose of a wearer's head to provide a three-dimensional virtual representation of objects in the wearer's environment. An electromagnetic (EM) tracking system can track head or body pose. A handheld user input device can include an EM emitter that generates an EM field, and the head-mounted AR device can include an EM sensor that senses the EM field. EM information from the sensor can be analyzed to determine location and/or orientation of the sensor and thereby the wearer's pose. The EM emitter and sensor may utilize time division multiplexing (TDM) or dynamic frequency tuning to operate at multiple frequencies. Voltage gain control may be implemented in the transmitter, rather than the sensor, allowing smaller and lighter weight sensor designs. The EM sensor can implement noise cancellation to reduce the level of EM interference generated by nearby audio speakers.
