Abstract
Abstract A method and associated apparatus for completing an incomplete trip in an electronic postage meter, comprising the steps of reading the state of bistable member after the trip cycle has commenced, setting a fatal error if the bistable member is in its home state prior to completion of the trip cycle, energizing a drive motor to try to complete the trip cycle, reading the state of the cycle switch, and de-energizing the drive motor after a maximum period of time.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
78 words
A method for completing an incomplete trip in an electronic postage meter, comprising the steps of: reading the state of a bistable member after the trip cycle has commenced; setting a fatal error if the bistable member is in its Home state prior to completion of the trip cycle; energizing a drive motor to try to complete the trip cycle; reading the state of the bistable member; de-energizing the drive motor after a selected maximum period of time.
Claim 2
Independent Claim
78 words
A method for completing an incomplete trip in an electronic postage meter, comprising the steps of: reading the state of a bistable member after the trip cycle has commenced; setting a fatal error if the bistable member is in its Home state prior to completion of the trip cycle; energizing a drive motor to try to complete the trip cycle; reading the state of the bistable member; de-energizing the drive motor after a selected maximum period of time.
Claim 3
Dependent Claim
24 words
The method recited in claim 1, wherein: the selected maximum period of time for energization of the drive motor is approximately one (1) second.
Claim 4
Dependent Claim
45 words
The method recited in claim 1, including the steps of: reading the state of the bistable member after a predetermined period of time; continuing to read the state of the bistable member during subsequent time intervals until the selected maximum period of time is reached.
Claim 5
Dependent Claim
29 words
The method recited in claim 3, including: setting a fatal error bit in a non-volatile memory if the bistable member is still in cycle after the final reading thereof.
Claim 6
Independent Claim
161 words
A method for completing an incomplete trip in an electronic postage meter, comprising the steps of: reading the state of a bistable member after the trip cycle has commenced; setting the fatal error if the bistable member is in its Home state prior to completion of the trip cycle; energizing a drive motor to try to complete the trip cycle; reading the state of the bistable member after the drive motor has been energized; de-energizing the drive motor if the bistable member is Home; running the drive motor for a selected maximum period of time while reading the bistable member during specified intervals if the bistable member is in an in Cycle state; de-energizing the drive motor prior to the end of the maximum period of time if the state of the bistable member is a Home state; and setting a fatal error if the bistable member is still In Cycle after the expiration of the selected maximum period of time.
Claim 7
Independent Claim
161 words
A method for completing an incomplete trip in an electronic postage meter, comprising the steps of: reading the state of a bistable member after the trip cycle has commenced; setting the fatal error if the bistable member is in its Home state prior to completion of the trip cycle; energizing a drive motor to try to complete the trip cycle; reading the state of the bistable member after the drive motor has been energized; de-energizing the drive motor if the bistable member is Home; running the drive motor for a selected maximum period of time while reading the bistable member during specified intervals if the bistable member is in an in Cycle state; de-energizing the drive motor prior to the end of the maximum period of time if the state of the bistable member is a Home state; and setting a fatal error if the bistable member is still In Cycle after the expiration of the selected maximum period of time.
Claim 8
Dependent Claim
108 words
Apparatus for completing an incomplete trip in an electronic postage, meter comprising: a bistable member having In Cycle and Home states; means for reading the state of said bistable member after the trip cycle has commenced; non-volatile memory means; address means for setting a fatal error bit in said non-volatile memory means if said bistable member is in its Home state prior to completion of the trip cycle; means for energizing a drive motor in an attempt to complete the trip cycle; said reading means reading the state of said bistable member; and means for de-energizing said drive motor after a selected maximum period of time has elapsed.
Claim 9
Dependent Claim
108 words
Apparatus for completing an incomplete trip in an electronic postage, meter comprising: a bistable member having In Cycle and Home states; means for reading the state of said bistable member after the trip cycle has commenced; non-volatile memory means; address means for setting a fatal error bit in said non-volatile memory means if said bistable member is in its Home state prior to completion of the trip cycle; means for energizing a drive motor in an attempt to complete the trip cycle; said reading means reading the state of said bistable member; and means for de-energizing said drive motor after a selected maximum period of time has elapsed.
Claim 10
Dependent Claim
27 words
The apparatus recited in claim 6, including: delay means for delaying a predetermined period of time after activation of said energizing means before reading said bistable means.
Claim 11
Dependent Claim
37 words
The apparatus recited in claim 6, wherein: said means for de-energizing said drive motor de-energizes the same if said bistable member is in its Home state prior to the expiration of the selected maximum period of time.
Claim 12
Dependent Claim
34 words
The apparatus recited in claim 6, wherein: said means for de-energizing said drive motor de-energizes the same after the selected maximum period of time has elapsed if said bistable member is still In Cycle.
Claim 13
Independent Claim
156 words
An apparatus for completing an incomplete trip in an electronic postage meter, comprising: a bistable member having In Cycle and Home states; means for reading the state of said bistable member after the trip cycle has commenced; non-volatile memory means for storing data; address means for storing a fatal error bit in said non-volatile memory if said bistable member is in its Home state during the trip cycle; means for energizing a drive motor in an attempt to complete the trip cycle; said reading means reading the state of the bistable member subsequent to the energization of said drive motor; means for de-energizing said drive motor after reading of the state of said bistable member by said reading means if said bistable member is in its Home state; and means for setting a fatal error bit in said non-volatile memory means after a predetermined maximum time period if said member is still its In Cycle state.
Claim 14
Independent Claim
156 words
An apparatus for completing an incomplete trip in an electronic postage meter, comprising: a bistable member having In Cycle and Home states; means for reading the state of said bistable member after the trip cycle has commenced; non-volatile memory means for storing data; address means for storing a fatal error bit in said non-volatile memory if said bistable member is in its Home state during the trip cycle; means for energizing a drive motor in an attempt to complete the trip cycle; said reading means reading the state of the bistable member subsequent to the energization of said drive motor; means for de-energizing said drive motor after reading of the state of said bistable member by said reading means if said bistable member is in its Home state; and means for setting a fatal error bit in said non-volatile memory means after a predetermined maximum time period if said member is still its In Cycle state.
