A tracking device is described. The tracking device receives, from a management server, configuration parameters including a first data transmission rate and a second data transmission rate. The tracking device automatically enters into an active mode of the tracking device. When operating in an active mode, the tracking device, is operative to transmit, in response to determining based on first motion sensor measurements that the asset is stationary, first location data at the first data transmission rate. In response to determining, based on second motion sensor measurements and motion definition parameters, that the asset is mobile, the tracking device is operative to transmit, second location data of the asset at the second data transmission rate.

A control apparatus, method and computer program code for controlling indoor positioning transitions. In response to detecting that a mobile apparatus is in an unmapped location, commanding the mobile apparatus to suspend generation of sensor data for indoor positioning with one or more sensors of the mobile apparatus. In response to an invoke mechanism, checking whether the mobile apparatus is likely to enter an indoor location for which indoor signal map data exists. If (YES) the checking indicates that the mobile apparatus is likely to enter the indoor location, commanding the mobile apparatus to start generating the sensor data for the indoor positioning with the one or more sensors, or else (NO) commanding the mobile apparatus to resume the suspension, and, in response to the invoke mechanism, performing the checking again.

A method of tracking entry to and exit from a confined space includes a portable radio beacon placed proximate to but outside the confined space transmitting a first radio signal with an identifier that is associated with the confined space. A mobile device receives the first radio signal, measures a first real-time value of a first measure of received signal strength or quality, and transmits a second radio signal with the identifier and the first real-time value. A base station receives the second radio signal, measures a second real-time value of a second measure of received signal strength or quality, and transmits data including the identifier, and the first and second real-time values. A computer receives the data, determines proximity of the mobile device to the confined space from the identifier, and determines whether the mobile device is outside or inside the confined space from the real-time values.

Biometric monitoring devices, including various technologies that may be implemented in such devices, are discussed herein. Additionally, techniques, systems, and apparatuses are discussed herein for providing power-conserving techniques and systems for efficiently utilizing a GPS receiver are described. The positional fix frequency of the GPS receiver may, according to some implementations, be modified or adjusted between various levels according to data from one or more non-GPS sensors. Such non-GPS sensors may include, for example, ambient light intensity or spectrum sensors, accelerometers, gyroscopes, magnetometers, heart rate sensors, galvanic skin response sensors, infrared sensors, etc.

In some example embodiments, for a place, a computer system accesses corresponding service data comprising pick-up data and drop-off data for requests, and accesses corresponding sensor data indicating at least one path of mobile devices of the requesters of the requests, with the at least one path comprising at least one of a pick-up path ending at the pick-up location indicated by the pick-up data and a drop-off path beginning at the drop-off location indicated by the drop-off data. In some example embodiments, the computer system generates at least one predicted geographic location using the paths indicated by the sensor data, and stores the at least one predicted geographic location in a database in association with an identification of the place.

An electronic apparatus comprises an indoor determiner and a notification determiner. The indoor determiner performs an indoor determination for determining whether or not a user of the electronic apparatus is located in an indoor. The notification determiner performs determination processing for determining whether or not the electronic apparatus transmits a notification outside the electronic apparatus based on a result of the indoor determination.

A processing device that processes detection strengths detected at a first detection position and a second detection position by a detector for detecting detection targets generated from a plurality of sources, includes a two-dimensionalization unit converting detection strengths a pair of sources into a two-dimensional distribution of coordinate points in which the detection strength for one source is represented by an X-axis value, and the detection strength for the other source is represented by a Y-axis value; a demarcation unit demarcating in the two-dimensional distribution of coordinate points, a predetermined region including a mixed region in which coordinate points relating to the first detection position and coordinate points relating to the second detection position are mixed; and a replacement unit replacing the two-dimensional distribution of coordinate points in a demarcated region that has been demarcated, with a two-dimensional distribution of coordinate points relating to another pair of sources.

A method, apparatus and computer readable storage medium are provided for determining absolute altitudes of individual floors represented by an indoor map. In the context of a method, location data is obtained representing at least one track of one or more users at least partially in a structure. The location data includes horizontal and vertical location information with the vertical location information representing an absolute altitude. The method also includes obtaining indoor map data representing different floors and indicating structural elements on the floors and determining track sections of the at least one track represented by the location data such that each track section can be assumed to be on a single floor. The method further includes at least partially comparing determined track sections with floors represented by the indoor map data and determining an absolute altitude of at least some of the floors represented by the indoor map data.

A device and method determine a location of a terminal by selecting one of a GPS signal and a beacon signal when a terminal moves indoors and outdoors. The device includes a measurement unit for measuring a signal strength of a GPS signal and a signal strength of a beacon signal, respectively; a selection unit for comparing the measured signal strengths and selecting one signal of the GPS signal and the beacon signal based on the comparison; and a determination unit for determining the location of the terminal using the selected signal. The selection unit compares the measured signal strengths based on at least one of a received signal strength indicator (RSSI) and a signal-to-noise ratio (SNR) to select a signal having a comparatively stronger strength, and selects a signal whose strength is increasing when the measured signal strengths are substantially equal to each other.
