    Abstract: A tracking method includes displaying visual content on a screen of a head mounted display (HMD). One or more base stations may be stationary with respect to the screen while the visual content is being displayed. In contrast, one or more objects may move with respect to the screen while the visual content is being displayed. Time-difference-of-arrival (TDoA) and/or time-of-flight (ToF) may be measured for one or more ultrasonic pulses transmitted from the base station, one or more objects, or HMD. Position and orientation of the objects and HMD may be calculated based on the TDoA and ToF. Different frequencies of pulses may be used to locate the HMD and the objects. An electromagnetic synchronization signal from the HMD and/or base station may be used to measure TDoA.

  • Patent number: 9948391
    Abstract: Techniques are disclosed for determining a light-based communication (LCom) receiver position. The techniques can be used to determine the position of a receiver relative to a specific luminaire within the field of view (FOV) of the receiver camera. The relative position may be calculated by determining the distance and the orientation of the receiver relative to the luminaire. The distance relative to the luminaire may be calculated using the observed size of the luminaire in an image generated by the receiver camera, the image zoom factor, and actual geometry of the luminaire. The orientation relative to the luminaire may be determined using a fiducial associated with the luminaire that can be used as an orientation cue. Once the position of a receiver relative to a luminaire is determined, the absolute position of the receiver may be calculated using the absolute position of the luminaire.

  • Patent number: 9682253
    Abstract: An integrated radiation therapy process comprises acquiring first objective target data related to a parameter of a target within a patient by periodically locating a marker positioned within the patient using a localization modality. This method continues with obtaining second objective target data related to the parameter of the target by periodically locating the marker. The first objective target data can be acquired in a first area that is apart from a second area which contains a radiation delivery device for producing an ionizing radiation beam for treating the patient. The localization modality can be the same in both the first and second areas. In other embodiments, the first objective target data can be acquired using a first localization modality that uses a first energy type to identify the marker and the second objective target data can be obtained using a second localization modality that uses a second energy type to identify the marker that is different than the first energy type.

  • Patent number: 9536163
    Abstract: An object position and orientation detection system and in particular one which is capable of describing observed movement in 3 dimensions. In one example, a spherical patterned marker with concentric rings is imaged using one or more digital cameras, and the resulting images are processed to determine the position and orientation of an object to which the patterned marker is attached. The method of optical tracking employed by the system allows motion to be determined in six degrees of freedom. In conjunction with a suitable display, such as a projector, an interactive white board or similar application can be realized.

  • Patent number: 9395205
    Abstract: A process for calibrating and correcting errors in laser measurement systems in situ, either remotely over the Internet or where the laser measurement system is physically located. In one embodiment, a number of targets are arrayed around the scanner and read by the software of a system. The laser scanner is rotated 180 degrees and the positions of the targets are read again. A correction factor is determined by calculation and displayed to show the expected improvement in accuracy of the laser measurement system. In a second embodiment, the laser scanner is positioned under a vehicle with targets at reference positions for which the measurements are known. The scanner readings are checked against the known values and a correction factor developed. This could be applied on a one-time basis or it can be programmed in the host computer where evaluation and compensation occur automatically.

  • Patent number: 9084887
    Abstract: Disclosed are systems and methods for characterizing interactions or proton beams in tissues. In certain embodiments, charged particles emitted during passage of protons, such as those used for therapeutic and/or imaging purposes, can be detected at relatively large angles. In situations where beam intensity is relatively low, such as in certain imaging applications, characterization of the proton beam with charged particles can provide sufficient statistics for meaningful results while avoiding the beam itself. In situations where beam intensity is relatively high, such as in certain therapeutic applications, characterization of the proton beam with scattered primary protons and secondary protons can provide information such as differences in densities encountered by the beam as it traverses the tissue and dose deposited along the beam path. In certain situations, such beam characterizations can facilitate more accurate planning and monitoring of proton-based therapy.

  • Publication number: 20150145151
    Abstract: A lithographic process is used to form a plurality of target structures (92, 94) distributed at a plurality of locations across a substrate and having overlaid periodic structures with a number of different overlay bias values distributed across the target structures. At least some of the target structures comprise a number of overlaid periodic structures (e.g., gratings) that is fewer than said number of different overlay bias values. Asymmetry measurements are obtained for the target structures. The detected asymmetries are used to determine parameters of a lithographic process. Overlay model parameters including translation, magnification and rotation, can be calculated while correcting the effect of bottom grating asymmetry, and using a multi-parameter model of overlay error across the substrate.

  • Patent number: 9025166
    Abstract: An exemplary embodiment of the present disclosure illustrates a proximity sensing method used in a controller of a proximity sensing device. Firstly, a cross talk value is initialized. After the cross talk value is initialized, whether the cross talk value should be updated is judged at least according to a first sensing value currently received from a sensing unit of the proximity sensing device. When the cross talk value is judged to be updated, the cross talk value is updated at least according to a first sensing value. Then, a compensated sensing value is obtained by subtracting the cross talk value from the first sensing value.
