Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
92 words
A method for performing remote diagnostics of an instrument by a computer executing a diagnostic software tool, comprising the method steps of: executing a software application on the computer to generate a graphical user interface depicting the instrument, accessing the depiction of the instrument to identify a component of the instrument for diagnosis, generating commands which can be understood by the instrument to request diagnostic information, communicating the generated commands to the instrument, sensing the requesting information on the instrument and communicating the sensed information to the computer for display and diagnosis.
Claim 2
Independent Claim
92 words
A method for performing remote diagnostics of an instrument by a computer executing a diagnostic software tool, comprising the method steps of: executing a software application on the computer to generate a graphical user interface depicting the instrument, accessing the depiction of the instrument to identify a component of the instrument for diagnosis, generating commands which can be understood by the instrument to request diagnostic information, communicating the generated commands to the instrument, sensing the requesting information on the instrument and communicating the sensed information to the computer for display and diagnosis.
Claim 3
Dependent Claim
25 words
The method as claimed in claim 1, said step of measuring operating parameters further comprises a multiplexed A/D converter to perform sensing on multiple parameters.
Claim 4
Dependent Claim
33 words
The method, as claimed in claim 1, further comprising the step of sensing the configuration of the instrument and communicating the sensed configuration to the computer for display on the graphical user interface.
Claim 5
Dependent Claim
36 words
The method as claimed in claim 3, wherein sensing the configuration of the instrument further comprises determining the configuration of the heated zone and the approximate wattage of a heater installed in a particular heated zone.
Claim 6
Dependent Claim
37 words
The method as claimed in claim 3, the step of sensing the configuration of the instrument further comprises sensing the type of cryogenic fluid coupled to the instrument, wherein, the cryo connector has a unique pin configuration.
Claim 7
Dependent Claim
21 words
The method as claimed in claim 3, the step of sensing the configuration of the instrument further comprises sensing valve configuration.
Claim 8
Dependent Claim
26 words
The method as claimed in claim 3, wherein, the computer is coupled to the instrument over standard telephone lines using a first and a second modem.
Claim 9
Dependent Claim
29 words
The method as claimed in claim 3, wherein the computer is coupled directly to the instrument by a cable and RS232 ports on both the computer and the instrument.
Claim 10
Dependent Claim
39 words
The method as claimed in claim 3, further comprising the step of coupling a second instrument to the first instrument, wherein the computer sends pass through commands to the first instrument which passes them through to the second instrument.
Claim 11
Independent Claim
163 words
An apparatus for diagnosis and repair of an instrument, comprising: an instrument, comprising: a communications port for receiving commands and for transmitting data, a sensing circuitry for measuring a plurality of instrument variables and operating parameters within the instrument, a processor having a command set comprising a plurality of diagnostic commands for requesting the sensing circuitry to measure operating parameters, a computer, remote from the instrument, comprising a processor and a communication port for communicating with the instrument, memory for storing definitions of instrument variables and operating parameters, a display which displays a graphical user interface depicting the instrument and instrument variables, a software application program which executes on the computer to generate the graphical user interface, to translate the instrument definitions into diagnostic commands and to set up a communications link over the communications port in both the computer and the instrument, wherein, instrument operating parameters may be requested from a remote location and communicated to the computer for diagnosis and repair.
Claim 12
Independent Claim
163 words
An apparatus for diagnosis and repair of an instrument, comprising: an instrument, comprising: a communications port for receiving commands and for transmitting data, a sensing circuitry for measuring a plurality of instrument variables and operating parameters within the instrument, a processor having a command set comprising a plurality of diagnostic commands for requesting the sensing circuitry to measure operating parameters, a computer, remote from the instrument, comprising a processor and a communication port for communicating with the instrument, memory for storing definitions of instrument variables and operating parameters, a display which displays a graphical user interface depicting the instrument and instrument variables, a software application program which executes on the computer to generate the graphical user interface, to translate the instrument definitions into diagnostic commands and to set up a communications link over the communications port in both the computer and the instrument, wherein, instrument operating parameters may be requested from a remote location and communicated to the computer for diagnosis and repair.
Claim 13
Dependent Claim
32 words
The apparatus for diagnosis and repair of an instrument as claimed in claim 10, said processor command set further comprising a plurality of commands that enable the computer to control the instrument.
Claim 14
Dependent Claim
23 words
