Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
169 words
A solid state relay, comprising: a. input circuit means having switch means therein; and b. bracketing break-before-make means connected to said switch means of said input circuit means, said bracketing break-before-make means operating to provide a first contact-break output signal at a first set of output terminals thereof generally concurrently with a first change of state of said switch means, said bracketing break-before-make means operating to provide a first contact-make output signal at a second set of output terminals thereof at a first delay time plus an on delay time after said first change of state of said switch means, said bracketing break-before-make means operating to provide a second contact-break output signal at said second set of output terminals generally conurrently with a subsequent change of state of said switch means, said bracketing break-before-make means operating to provide a second contact-make output signal at said first output terminals thereof at a second delay time plus said on delay time after said subsequent change of state of said switch means.
Claim 2
Dependent Claim
169 words
A solid state relay, comprising: a. input circuit means having switch means therein; and b. bracketing break-before-make means connected to said switch means of said input circuit means, said bracketing break-before-make means operating to provide a first contact-break output signal at a first set of output terminals thereof generally concurrently with a first change of state of said switch means, said bracketing break-before-make means operating to provide a first contact-make output signal at a second set of output terminals thereof at a first delay time plus an on delay time after said first change of state of said switch means, said bracketing break-before-make means operating to provide a second contact-break output signal at said second set of output terminals generally conurrently with a subsequent change of state of said switch means, said bracketing break-before-make means operating to provide a second contact-make output signal at said first output terminals thereof at a second delay time plus said on delay time after said subsequent change of state of said switch means.
Claim 3
Dependent Claim
37 words
The combination as claimed in claim 1 wherein solid state contact means is connected to first set of output terminals of said bracketing break-before-make means for being actuated thereby to change state to control a circuit function.
Claim 4
Dependent Claim
38 words
The combination as claimed in claim 1 wherein solid state contact means is connected to said second set of output terminals of said bracketing break-before-make means for being actuated thereby to change state to control a circuit function.
Claim 5
Dependent Claim
59 words
The combination as claimed in claim 1 wherein first solid state contact means is connected to said first set of output terminals thereof and second solid state contact means is connected to said second set of output terminals thereof, both said first and said second solid state contact means being actuated to change state to control a circuit function.
Claim 6
Dependent Claim
165 words
A solid state relay, comprising: a. input circuit means having switch means therein; and b. bracketing break-before-make means connected to said switch means of said input circuit means, said bracketing break-before-make means operating to provide a first contact-break output signal at a first set of output terminals thereof at an off delay time after a first change of state of said switch means, said bracketing break-before-make means operating to provide a first contact-make output signal at a second set of output terminals thereof at a first delay time after said first change of state of said switch means, said bracketing break-before-make means operating to provide a second contact-break output signal at said second set of output terminals at said off delay time after a subsequent change of state of said switch means, said bracketing break-before-make means operating to provide a second contact-make output signal at said first output terminals thereof at a second delay time after said subsequent change of state of said switch means.
Claim 7
Dependent Claim
165 words
A solid state relay, comprising: a. input circuit means having switch means therein; and b. bracketing break-before-make means connected to said switch means of said input circuit means, said bracketing break-before-make means operating to provide a first contact-break output signal at a first set of output terminals thereof at an off delay time after a first change of state of said switch means, said bracketing break-before-make means operating to provide a first contact-make output signal at a second set of output terminals thereof at a first delay time after said first change of state of said switch means, said bracketing break-before-make means operating to provide a second contact-break output signal at said second set of output terminals at said off delay time after a subsequent change of state of said switch means, said bracketing break-before-make means operating to provide a second contact-make output signal at said first output terminals thereof at a second delay time after said subsequent change of state of said switch means.
Claim 8
Dependent Claim
38 words
The combination as claimed in claim 5 wherein solid state contact means is connected to said first set of output terminals of said bracketing break-before-make means for being actuated thereby to change state to control a circuit function.
Claim 9
Dependent Claim
38 words
The combination as claimed in claim 5 wherein solid state contact means is connected to said second set of output terminals of said bracketing break-before-make means for being actuated thereby to change state to control a circuit function.
Claim 10
Dependent Claim
59 words
The combination as claimed in claim 5 wherein first solid state contact means is connected to said first set of output terminals thereof and second solid state contact means is connected to said second set of output terminals thereof, both said first and said second solid state contact means being actuated to change state to control a circuit function.
