摘要： A method of producing a workpiece involves positioning the workpiece at a current processing position indicated by a hard-coded part program and then collecting position data which defines the positional arrangement of a current target area of the workpiece. The collected position data is processed by comparing it to reference position information that represents the positional arrangement of the same target area in an ideal workpiece employed in the development of the part program. The position of the workpiece (and hence the target area) is adjusted in accordance with the comparison results. A laser shock processing operation is performed on the workpiece at the current target area following the position adjustment step.

摘要： An apparatus is provided, the apparatus comprising: (i) a diode-pumped solid-state laser oscillator configured to generate a pulsed laser beam having predefined beam characteristics corresponding to a current setting selection of a controller; and (ii) an amplifier configured to amplify an energy and modify a beam profile of the pulse laser beam. A beam detector is coupled to the generated beam to monitor a combination of: (i) a beam pulse width; (ii) a beam diameter; and (iii) an energy level, and generates an error signal to be sent back as a feedback signal to the controller. The controller configures the current source to output a correction current to tune the DPSSL oscillator, the wave plate, and the first polarizer to rotate a correction polarization angle and adjust the energy amplification or temporal profile to within a defined performance tolerance.

摘要： A temperature sensing system for over-heat detection includes a temperature sensing cable, interface unit and termination unit. The interface unit is configured to issue interrogation, communication and power signals to the termination unit through the temperature sensing cable. During normal operation issuance of the interrogation signal results in no reflection pulses, as the signal is dissipated through the termination resistance in the termination unit. When an over-heat, short circuit or open circuit condition exists, a reflected pulse is detected by the interface unit and this information is used to determine the type and location of the condition. The interface unit is also configured to supply power to the termination unit which in turn is stored in the termination unit to power its operations, including setting of the resistor values. The termination unit is used as an instrument of calibration in the subject system.

摘要： Methods and apparatus for reading a luminescent and substantially transparent bar code 1 on a background surface 2 whose reflectance may vary over the coded area. Light 7 scans (70), and excites luminescence 8 in, the bar code 1. The light 7 also reflects (9) without luminescence from the background surface 2 of the bar code 1. A first electrical or optical signal 11 is provided (4) responsive to the reflected nonluminescent light 9, and a second electrical or optical signal 10 is provided (4) responsive to the luminescent 8. Typically the first signal 11 is processed (5) to provide a third signal 31 that varies with background reflectance substantially as does the second signal 10; and the second and third signals 10, 31 are combined (5) to provide a fourth signal 12 that is substantially independent of background reflectance in the coded area, and which is decoded (6) to provide the desired reading.
