Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
80 words
A scanning device for reading bar code symbols, comprising: (a) a light source for generating a light beam; (b) a sensor for detecting the intensity of reflected light from said light beam and generating an electrical signal proportional to the intensity of said reflected light: and (c) signal processing means in said device to receive said electrical signal and to produce a digitized signal corresponding to the bar code symbol; wherein said scanning device is housed in a PCMCIA card.
Claim 2
Dependent Claim
80 words
A scanning device for reading bar code symbols, comprising: (a) a light source for generating a light beam; (b) a sensor for detecting the intensity of reflected light from said light beam and generating an electrical signal proportional to the intensity of said reflected light: and (c) signal processing means in said device to receive said electrical signal and to produce a digitized signal corresponding to the bar code symbol; wherein said scanning device is housed in a PCMCIA card.
Claim 3
Dependent Claim
33 words
A scanning device according to claim 1 including a scanner in said device for scanning said light beam along a scan line across the bar code symbol, said scanner including a scan element.
Claim 4
Dependent Claim
19 words
A scanning device according to claim 1 including an optical means for directing and focusing said beam of light.
Claim 5
Dependent Claim
33 words
A scanning device according to claim 1 including a control circuit for de-energizing said light source after said signal processing means has produced a digitized signal corresponding to a valid bar code symbol.
Claim 6
Dependent Claim
14 words
A scanning device according to claim 3 wherein said optical means is a mirror.
Claim 7
Dependent Claim
15 words
A scanning device according to claim 1 wherein the light source is a laser diode.
