  • Patent number: 10291339
    Abstract: A method and system configured to evaluate near range communications quality in an environment. Data describing an environment is obtained from at least one data source (202). The data describing the environment is processed (204) to generate a ground-plane data set (206) describing a ground-plane of the environment, and a 3D object data set (206) describing 3D objects in the environment. These data are used to compute (208) a propagation path between a first location and a second location in the environment, and a near range communications quality characteristic of the propagation path is computed (210).

  • Patent number: 10162177
    Abstract: A method and apparatus for self-relative body tracking in virtual reality systems using magnetic tracking is disclosed, which allows more accurate tracking of a user's body relative to the user's field of vision. A head-mounted magnetic tracking (HMMT) system is used, in which other parts of a user's body are tracked relative to the HMD on the user's head, rather than relative to a base station. This results in less distortion of the magnetic field used for tracking and thus allows for more accurate determination of the position and orientation of a user's body parts relative to the user's field of vision, so that a more accurate avatar may be presented on the HMD to the user. This allows the avatar of the user's body part to be shown in a location that corresponds closely to its physical position. In an alternative embodiment, multiple portions of the user's body may be tracked.

  • Patent number: 9419731
    Abstract: Examples herein include methods and systems for determining signal strength maps for wireless access points robust to measurement counts. An example method comprises receiving data related to RSSI for a wireless AP for a plurality of locations of an area, and determining an intermediary signal strength map for the wireless AP based on the received data related to the RSSI for the wireless AP. The method also includes associating the intermediary signal strength map to a regularized signal strength map for the wireless AP that is based on a diffusion mapping model of signal strength. A given partition of the regularized signal strength map is linked to one partition of the intermediary signal strength map. The method also includes providing an output signal strength map for the wireless AP including values of the regularized signal strength map modified based on values of the intermediary signal strength map.

  • Patent number: 9329044
    Abstract: A guidance system (SG) for an individual (IND) moving in an unknown environment establishes a guidance loop (B) between a measurement module (MM) placed on the individual and a remote guidance platform (PG). In the measurement module, a means (CP) collects measurement data (DM) that are transmitted by another means (UC1) of transmission to the guidance platform via a first communication channel. Then, at the guidance platform, a means (UT2) determines the tactical position data (DST) from the transmitted measurement data (DM), and another means (UC2) transmits determined guidance data (DG) from the tactical position data to a communication device of the individual by means of a second communication channel (R2), thus closing the guidance loop.

  • Patent number: 9319260
    Abstract: An OFDM receiver receives OFDM symbols in the frequency domain and comb filters and then punctures the OFDM symbols to leave symbols with actual pilot information and with null values at the data symbols. The receiver provides the punctured OFDM symbols to an OFDM symbol queue. A virtual pilot interpolator is coupled to the punctured OFDM symbol storage to generate virtual pilot information introduced to OFDM symbols. The interpolator may be a two dimensional Wiener filter. The receiver also includes a time domain channel estimator that processes a first OFDM symbol including virtual pilot information to generate a channel impulse response for the first OFDM symbol. A frequency equalizer equalizes the OFDM symbol in response to the channel impulse response for the first OFDM symbol.

  • Patent number: 9297660
    Abstract: A system determines parameters representing the orientation of a solid in movement within a first vector field and a second vector field. A first triaxial sensor and a second triaxial sensor are connected to the solid and measure the components of the respective vector fields along the axes of the sensors, obtaining corresponding first and second vectors. A processor determines the rotation matrix of the solid, using a correction module for delivering a first corrected vector, and calculating a third vector which is not coplanar to the plane formed by the first corrected vector and the second vector, such that the angles of the axis system formed by the third vector and the first corrected vector and the second vector remain constant.

  • Patent number: 9229093
    Abstract: A method for estimating a location of an electronic device and an associated apparatus are provided, where the method includes the steps of: sending a pre-association broadcast request frame by the electronic device to multiple responders in a wireless network system; receiving a plurality of response frames corresponding to the pre-association broadcast request frame from the multiple responders; and performing a timing measurement according to information carried by the plurality of response frames for determining the location of the electronic device. For example, each of the response frames is sent from one of the responders, and each of the responders sends only one response frame corresponding to the pre-association broadcast request frame. As a result, the power consumption can be greatly decreased, and the related art problem of insufficiency of the total channel capacity of the wireless network system can be prevented.

  • Patent number: 9151823
    Abstract: A wireless communication device capable of more accurately estimating its location in an indoor environment is disclosed. In an indoor environment, the wireless communication device may seek to generate a fingerprint map so as to later identify its location within the environment. However, the map requires the device to at least estimate its current position. Therefore, the device includes one or more sensors to identify each of a bearing and a speed of the device. For example, the speed may be determined based on sensed steps and a stored step length. This information may then be used to estimate the device's location as it moves through the indoor environment.

    Abstract: A method and associated system for estimating a position of an object. A radio wave is received from each radio frequency identification (RFID) tag of N RFID tags affixed to the object at different positions at the object (N?2). A position of each RFID tag is detected from the received radio waves. A position of each RFID tag is estimated from analysis of the detected positions. The estimating includes utilizing, for n=1, 2, . . . , N, a specified probability function P(?pn|pn) denoting a probability that the estimated position of RFID tag n is ?pn if the detected position of RFID tag n is pn, wherein ?pn and pn are vectors from an origin of a coordinate system to the detected position and the estimated position, respectively, of the RFID tag n. The position of the object is ascertained from analysis of the estimated positions.

  • Patent number: 9081080
    Abstract: A position fix for a mobile platform is determined using RSSI values for wireless signals received from access points (APs), at least one of which has dynamic transmission power control. The transmission power data for the APs is received from an entity separate from the APs, e.g., a central entity or a positioning assistance server. The RSSI values for wireless signals received from the APs are acquired, as is an RSSI heatmap. Using the transmission power data, the RSSI values and the RSSI heatmap, the position fix for the mobile platform is determined. The position fix may be determined by the mobile platform or a positioning assistance server. Additionally, a server may receive transmission power data for APs and may provide to a mobile platform RSSI heatmap information based on the transmission power data. The RSSI heatmap information may be, e.g., the transmission power data or a RSSI heatmap.
