Title: Detector of optical sensor signal
Inventor: GEORGE JOHN BARRET
IPC: H04N9/31
Filed: 2000-06-29
Abstract: PROBLEM TO BE SOLVED: To clearly detect a sensor output signal level by detecting a 1st signal, that is produced in response to the illumination level of an image projected by an optical sensor via a detector, when the 1st signal exceeds the prescribed detection threshold and then producing a 2nd signal to change the detection threshold. SOLUTION: The output of a sensor detector 275 is equal to a pulse signal 202 of forward direction which is supplied to the input of a digital convergence IC STV2050. The leading edge of the signal 202 is sampled, both the vertical and horizontal counters are stopped, and accordingly the count value decides a specific part in a measurement matrix where an illuminated sensor exists. The sensor current is measured by means of a reference current Iref, that increases controllably until the detector 275 is switched to show the stop of sensor illumination. The value of reference current that is shown by the detector 275 shows a level of illumination that is incident on the sensor.

Title: Printer and data receiver
Inventor: NAKANO KATSUMI
IPC: B41J5/30
Filed: 2000-06-30
Abstract: PROBLEM TO BE SOLVED: To check the matching of a large volume of data in a short time without printing out the large volume of data actually.

Title: Setting of characteristic of electromagnetic transponder system exclusively for remote coupling operation
Inventor: WUIDART LUC
IPC: G06K17/00
Filed: 2000-07-19
Abstract: PROBLEM TO BE SOLVED: To use a transponder and/or a terminal exclusively in a comparatively remote area by setting the characteristics of component elements of an oscillation circuit of the transponder to quickly attenuate the coupling coefficient between the oscillation circuits of both terminal and transponder when the distance set between the transponder and the terminal is smaller than a prescribed value. SOLUTION: When the distance between a transponder 10 and a terminal 1 is decreased, the coupling coefficient between the oscillation circuit of the transponder 10 and the terminal 1 is reduced quickly. The best measure of this problem shows that the optimum coupling point must be approximately equal to the center of a desirable distance operation area. When the distance between the transponder 10 and the terminal 1 deviates from the distance to the operation area, the coupling coefficient is quickly reduced and no power is supplied to the transponder 10 thereafter.  The largest operation point is selected so that the voltage between the input terminals 11 and 12 of the transponder 10 lies in the interval between the voltage for which the least operating voltage of the transponder 10 corresponds to an inflection point and the voltage of the parallel oscillation circuit when the optimum coupling is secured between both oscillation circuits.
