  • Patent number: 10190854
    Abstract: A shooting target system exhibiting a ballistic plate having a front face, capable of being struck by aimed projectiles, and an opposed rear face which is made to accept an array of sensors for the detection and transmittal of ballistic strike information. The array of sensors is applied to the opposed rear face and is made to cover a major portion of the rear face. Each sensor is responsive to discrete areas of vibration of the ballistic plate, resulting from a projectile strike, which generates a strike signal that is transmitted to a processor connected to each of the sensors. The processor determines which of the sensors is/are first activated by a projectile strike during a limited time interval and calculates the location of a projectile strike based on the location of the activated sensors and whether each sensor's input is above or below a preselected threshold.

  • Patent number: 9967539
    Abstract: A method and a system are disclosed that use a double-readout technique to generate timestamps and grayscale values for pixel-specific outputs of a pixel row in a pixel array in which the pixel array forms an image plane and the row of pixels forms an epipolar line of a scanning line on the image plane. For a pixel-specific output that exceeds a threshold, a timestamp value and a grayscale value are generated and associated with the pixel-specific output. If a pixel-specific output does not exceed the threshold and no timestamp is generated (i.e., a missing timestamp), a grayscale value for the pixel-specific output is generated and associated with the pixel-specific output. Timestamps errors may be corrected that may be caused by missing timestamps, timestamps that are associated with pixel clusters and outlier timestamps, i.e., pixel-specific outputs that are not consistent with a monotonic relationship of timestamp values under normal conditions.

  • Patent number: 9631914
    Abstract: Systems and methods for calibrating sensor arrays. An exemplary system measures a distance to a target object with the sensors. The system calculates a first position of the target object based on measurements from a first pair of the sensors and calibrated sensor coordinates for the first pair, calculates a second position of the target object based on measurements from a second pair of the sensors and the calibrated sensor coordinates for the second pair, and calculates a third position of the target object based on measurements from a third pair of the sensors and the calibrated sensor coordinates for the third pair. The system then compares the first position, the second position, and the third position calculated for the target object, and determines that the calibrated sensor coordinates for one or more of the sensors are inaccurate if a difference between the first, second, and third positions exceeds a threshold.

  • Patent number: 8687060
    Abstract: This invention provides a system and method for estimating the time of a set of pulses based upon a plurality of position measurements of a moving object provided by a non-contacting sensor, such as a one-dimensional optical sensor that tracks movements of object features and reports position measurements with respect to time. Position measurements determine the estimated velocity. The velocity and position measurement allow the timing of a next pulse to be updated, based upon the time of the previous pulse. The pulse is output at the time of the last updated time before the first new position measurement received after the estimated pulse output time. The system allows pulses to be precisely delivered at predetermined motion distances. Where the distance is too short for the measurement rate, the system compares estimated pulse times to clock-generated pulse times and updates the clock-generated pulse times based upon the difference.

  • Patent number: 7718938
    Abstract: A spatial information detection system, which is capable of, even when detecting spatial information from a common target space by use of a plurality of detection devices, achieving accurate detection without causing interference between the detection devices. Each of the detection devices has a light emitting source for projecting light intensity-modulated with a modulation period into the target space, a photodetector for receiving light from the target space, and an evaluation portion for detecting the spatial information of the target space from a change between the light projected from the light emitting source and the light received by the photodetector. The system includes a timing control portion for controlling the timings of projecting the lights from the light emitting sources such that a light projection period of the light emitting source of one of the detection devices does not overlap with the light projection period of the light emitting source of another detection device.

  • Patent number: 7655895
    Abstract: Land-based vehicle including an arrangement for monitoring objects in or about a vehicle which includes a source from which illumination is emitted into an area in or about the vehicle, a receiver arranged to receive illumination reflected from an object in the path of the illumination, a light-regulating component arranged in front of the receiver to regulate reception of illumination by the receiver, and circuitry coupled to the source, the receiver and the light-regulating component. The light-regulating component is modulated to enable a determination of a distance between an object from which the illumination has been reflected and the receiver. The circuitry obtains information about objects from which the received illumination has been reflected other than distance information and associates with the objects distances between the objects and the receiver. This improves the ability to control vehicular systems based on the presence of objects in or about the vehicle.

  • Patent number: 7635831
    Abstract: The ratio is calculated between a first number of pixels and a second number of pixels on an image sensor. The first number of pixels is counted between two certain points projected on the image sensor from a first section of a plane. The second number of pixels is counted between two certain points projected on the image sensor from a second section, adjacent to the first section, of the plane. The number of pixels between two certain points increases if the image sensor gets closer to the plane, while the number of pixels between two certain points decreases if the image sensor gets remoter from the plane. The inclination of the image sensor can be determined relative to the plane based on the ratio between the two numbers of pixels. The attitude or inclination of the image sensor can in this manner be detected with a high accuracy.

  • Patent number: 7547870
    Abstract: One or more fixed-orientation fanned laser beams and one or more displacement measurement devices to precisely measure the orientation of a payload platform are disclosed in a metrology system and method. The measurement devices may be distributed at locations across a payload platform such that displacement changes of these devices can be used to accurately determine platform pointing. Laser beam transmitters may be fixed in the same reference block to which a spacecraft attitude sensor is mounted. Fanned laser beams are transmitted from these sources to the measurement devices so that their displacements can be determined with respect to the plane of the fanned beams and thereby with respect to the spacecraft attitude sensor. Only a small number of fixed laser beams are needed to achieve precision measurements at a reduced cost, weight and power, and with increased system reliability and simplified system integration.

  • Patent number: 7415212
    Abstract: A transmitter formed of two or more light-emitting sections such as LEDs, which are physically arranged in a predetermined manner, is disposed in the real world object, and each light-emitting section transmits data by flashing at a flashing pattern representing the transmission data of a predetermined bit length. A receiver, on the other hand, includes a photoreceiving section formed from a two-dimensional photoreceiving surface, decodes the transmission data on the basis of the photoreceived flashing pattern, and recognizes the spatial information of an object on the basis of the flashing position on the two-dimensional photoreceiving surface. Therefore, information, such as an ID, can be obtained from the object in the real world, and also, the spatial position of the object can be recognized at the same time.
