Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
92 words
A device for detecting light, the device comprising: a detector configured to detect light and to generate an output representative of the detected light; an analog data collection device configured to compute the total amount of light detected based on a signal corresponding to the output of the detector; a discrete data collection device configured to compute the total amount of light detected based on a signal corresponding to the output of the detector; and a system controller configured to select between the analog and discrete devices based on a preselected criterion.
Claim 2
Independent Claim
92 words
A device for detecting light, the device comprising: a detector configured to detect light and to generate an output representative of the detected light; an analog data collection device configured to compute the total amount of light detected based on a signal corresponding to the output of the detector; a discrete data collection device configured to compute the total amount of light detected based on a signal corresponding to the output of the detector; and a system controller configured to select between the analog and discrete devices based on a preselected criterion.
Claim 3
Dependent Claim
20 words
The device of claim 1 , further comprising at least two light sources, wherein the criterion is the light source.
Claim 4
Dependent Claim
16 words
The device of claim 1 , wherein the criterion is the amount of the light detected.
Claim 5
Dependent Claim
16 words
The device of claim 1 , wherein the criterion is the intensity of the light detected.
Claim 6
Dependent Claim
24 words
The device of claim 4 , wherein the analog device is used to determine whether the amount of light has exceeded the threshold value.
