  • Patent number: 11947719
    Abstract: A method for predicting eye movement in a head mounted display (HMD). The method including tracking movement of an eye of a user with a gaze tracking system disposed in the HMD at a plurality of sample points. The method including determining velocity of the movement based on the movement of the eye. The method including determining that the eye of the user is in a saccade upon the velocity reaching a threshold velocity. The method including predicting a landing point on the display of the HMD corresponding to a direction of the eye for the saccade.

  • Publication number: 20180087880
    Abstract: A method and apparatus for presenting a target wherein a horizontal support member is supported above a surface and a target is supported from the horizontal member. From a starting position the target is allowed to deflect when struck by a projectile. By minimizing the forward looking profile of the horizontal support member, projectiles are less likely to strike it.

  • Publication number: 20170343324
    Abstract: A method and apparatus for supporting a post used to support a ballistic target. A post is supported in a vertical position by retention in a post stand. The post stand is assembled using a bottom plate, a top plate and two side plates. Once assembled, the post stand receives a post. Two types of posts are contemplated. One post type is made of wood. A second post type is made of steel and projects a low profile toward a shooter. A top hanger is then installed over the post and provides mounting holes so that a target can be suspended therefrom.

  • Publication number: 20170184378
    Abstract: A method and system for suspending a target above a surface that provides for supporting a support member above the surface. A hanger is used to suspend a target from the support member. When the target is hanging from the support member, it is induced into an angle so that its top portion is closer to a shooter. When the target is struck by an incoming projectile, it is allowed to pivot downward from its initial position and the target is also restrained from rotating about the axis of suspension.

  • Patent number: 7558156
    Abstract: A method of locating an acoustic source, the method comprising sampling said acoustic source at a plurality of acoustic receivers having different locations, each acoustic receiver time-stamping a respective received acoustic sample using a system time, each acoustic receiver sending said time-stamped acoustic sample to a central controller, the central controller determining the location of the acoustic source in response to receiving the time-stamped sound source samples from the plurality of receivers.

  • Patent number: 7411437
    Abstract: Generally, the embodiments presented are directed to circuits and methods for triggering an event at a fraction of a clock cycle. A triggering circuit can comprise two or more input circuits that output an event signal. The event signal is received by one of two or more delay circuits that trigger the event signal at a predetermined phase of the clock cycle by moving the event signal from a first clock domain to another clock domain. By triggering the event at a phase division, the triggering circuit outputs signals at a rate faster than the clock cycle.

  • Publication number: 20070136018
    Abstract: A system and method are disclosed for calibrating non-linear behavior using attenuated stimuli and responses which allows for calibration with unknown stimulus and less expensive sources and receivers. The device under test is stimulated with a signal and then an attenuated version of the same signal, so that non-linear differences between responses can be attributed to the device rather than the signal source. Alternatively, or in conjunction with attenuation of the stimulus, the output of the device at different response amplitudes can be selectively attenuated such that the receiver measures approximately the same amplitude. This allows non-linear differences between measurements to be attributed to the device rather than the receiver. Two or more different signal sources can also be used, where responses are measured for each signal individually and then for at least one linear combination of signals.

  • Publication number: 20070127318
    Abstract: Generally, the embodiments are directed to circuits and methods for time stamping an event at a fraction of a clock cycle. A time stamping circuit comprises two or more detection circuits. The detection circuits receive an event-in signal and generate event signals based on a clock phase at which the event-in signal was received. A decoder receives the event signals and outputs an event-out signal and a time stamp that represents the phase at which the event-in signal was detected. By time stamping the event-in signal to a phase division, the time stamping circuit detects event signals that occur at a rate faster than the clock cycle.

  • Publication number: 20060250288
    Abstract: A method for calibrating time interleaved samplers comprising applying a calibration signal to a time-interleaved sampling device, wherein the signal is coherent with at least one sample clock on the device and is periodic and has a predetermined spectral content and frequency, sampling, by said time-interleaved sampling device, the calibration signal at a plurality of phases to form samples, averaging the formed samples, and calculating the phase error of each sample based on the average calibration signal sample.
