Patent number: 9874441Abstract: A time-of-flight laser distance device includes a laser transmitter, a laser pulse return detector to receive reflected laser pulses, and comparators with respective first and second trip levels. A preliminary distance to a target is based on a linear ramp as a function of lapsed time from laser pulse generation through an effective time period wherein an associated return pulse is detected. Time-of-flight values associated with a leading edge of the return pulse are obtained at each of the first and second trip levels. A time difference is determined between the obtained values, and a correction factor is applied with respect to the preliminary measured distance based on the determined time difference. A dual ADC may be used wherein the leading edge of the return pulse is calculated by measuring a slope associated with the time-of-flight values and extrapolating a slope origin to a zero crossing point.Type: GrantFiled: January 16, 2014Date of Patent: January 23, 2018Assignee: OPTI-LOGIC CORPORATIONInventors: Gail Hines, William L.

Patent number: RE46480Abstract: The present invention is a laser ranging device that incorporates an internal tilt sensor, an internal temperature sensor, and an internal pressure sensor. The tilt sensor is used to measure the target's vertical angle relative to the horizontal reference plane. Digital signal processing circuitry controls the firing of the laser pulse, calculation of time-of-flight range, measurement of the vertical angle of the tilt sensor, measurement of ambient temperature and storage of tilt sensor and temperature sensor calibration data. The digital signal processing circuitry then provides the user temperature corrected ballistic ranging information, including corrected horizontal range. Additionally, an automatic gain control system minimizes the effects of target to target variance in reflectivity and its associated errors. It is also an object of this invention to electronically minimize errors in the measurement of a vertical angle caused by housing vibration and by temperature variance errors.Type: GrantFiled: March 29, 2007Date of Patent: July 18, 2017Assignee: OPTI-LOGIC CORPORATIONInventors: Robin H.
