Filed: 1991-07-02
Abstract: PURPOSE:To use this device for an outside load which necessitates a high speed response by providing an output switching means, and fetching the output of a digital/analog(DA) converter through a buffer amplifier or directly. CONSTITUTION:When switches 5 and 7 are turned into ON states, and a switch 6 is turned into an OFF state by a switching control signal from a control terminal 8, the output signal of a DA converter 2 is outputted through an operational amplifier 3 to an outside output terminal 4. At that time, the influence of the outside load is eased by the operational amplifier 3, a high precision is held, and this device can be used for a large power load. On the other hand, when the switches 5 and 7 are turned into OFF states, and the switch 6 is turned into ON state by the switching control signal from the control terminal 8, the output signal of the DA converter 2 is outputted directly to the outside output terminal 4. At that time, the output signal of the DA converter 2 is not outputted through the operational amplifier 3, so that the high speed response can be attained. Thus, this device can be used not only for the large power load, but also for the load which necessitates the high speed response.

Title: Method for reading of bar code
Inventor: ROSA RALPH
IPC: G06K19/06
Filed: 1993-06-30
Abstract: PURPOSE: To provide a method for reading a bar code which is encoded by the relative width of one or both of bars and spaces and by the relative height of the bar by scanning with long laser beams across the bar code which is height-modulated or width-modulated. CONSTITUTION: The bar code is scanned by a light source generating almost oval illumination spot 200. The bar code may be a height modulation code (A) or a width modulation code (B). The intensity of light reflected from the bar code changes when the illumination spot crosses the bar code. When the illumination spot 200 crosses the spaces (205'), reflected light intensity reaches a maximum value and it reduces when it crosses a short bar [205" of (A)] or a fine bar [205" of (B)]. Reflected light intensity reaches a minimum value when it crosses the long bar [205"' of (A)] or the thick bar [205"' of (B)]. Consequently, it is clear that the patterns of (A) and (B) become the patterns of reflected light intensity and they can be decoded.
