Abstract: A system and method for a semi-active laser seeker combining a temporal and a spatial sensor to form a seeker with a wide angle FOV and low angle error for use with spinning projectiles with spin rates of up to 300 Hz. The FOV is about 40 degrees and the angle error is less than 0.1 degrees. The seeker utilizes a CCA and fits into a small, low cost package, of about 1.5 in3 or less.

Abstract: A magnetostrictive sensing instrument comprises a probe including a tube having a near end and a distal end. A magnetostrictive wire is in the tube. An adaptor at the tube near end includes a probe circuit comprising a drive circuit for the magnetostrictive wire, a pickup sensor, a preamplifier and a memory circuit storing calibration parameters for the probe. An instrument housing includes a control circuit. A connector is operatively disposed between the instrument housing and the adaptor and comprises electrical conductors for connecting the control circuit to the probe circuit.

Abstract: A loop powered process instrument comprises a signal processing circuit measuring a process variable and developing a measurement signal representing the process variable. A control system, for connection to a power supply using a two-wire process loop, controls current on the loop in accordance with the measurement signal. The control system implements a diagnostic function comprising selectively controlling loop current at first and second select current levels and measuring terminal voltage at each of the first and second select current levels to determine if power supply voltage is at a select voltage level.
