Patent number: 6058270Abstract: A low cost, low power photometric circuit suitable for use in a low end camera includes a first counter for counting successive pulses produced by a first oscillator having a substantially constant oscillation frequency and a second counter for counting successive pulses produced by a second oscillator having an oscillation frequency which varies in accordance with ambient brightness. The ambient brightness is judged according to outputs of the counters so that even if the oscillation frequency of the second oscillator varies only slightly due to a change in ambient brightness, the slight variation is easily detectable as an accumulated count value. Accordingly, costly, high-precision components are not needed. The low cost photometric circuit requires no microcomputer, analog/digital converter or comparator and can be fabricated in a single integrated circuit operated at a low voltage of 1V or less, and is thus suitable for incorporation into a low end camera.Type: GrantFiled: March 16, 1999Date of Patent: May 2, 2000Assignee: Seiko Precision Inc.Inventors: Yoichi Seki, Hajime Oda

Patent number: 6043874Abstract: A system and method for checking and calibrating, if necessary, the orientation of a rotating laser beam as projected by a laser transmitter is provided. The laser transmitter is initially adjusted so that the rotating laser beam defines a plane which will be substantially horizontal if the transmitter is properly calibrated. A retroreflective target is positioned a predetermined distance from the transmitter. A known point on the transmitter is aligned in the direction of the retroreflective target. The laser beam is reflected from the retroreflective target back to the laser transmitter. A photodetecting system within the laser transmitter generates a signal representative of the position of the laser beam on the target. The laser transmitter is then rotated about a reference axis until the position of the laser beam on the target is determined with respect to each of the remaining coordinate axes.Type: GrantFiled: April 10, 1998Date of Patent: March 28, 2000Assignee: Spectra Precision, Inc.Inventor: Philip Lynn Detweiler
