Abstract: An improved recovery method utilizes sequence numbers to order log records and reduce the excess compensating actions due to a failure during recovery.  Next undo records are written to the log after a preset number of compensating actions which include the sequence number of the record currently being scanned.  After a failure, all records between the next undo record and the record having the sequence number included in the next undo record are ignored during when the log is scanned backwards.

Title: Method for maintaining mailpiece integrity
Inventor: CHANG SUNG S
IPC: G07B17/00
Filed: 1996-05-03
Abstract: A method for maintaining mailpiece integrity in a mailing system when a mechanical module experiences an error. For one category of errors, the mailing system may automatically recover from the error without operator intervention. For the remaining category of errors, the mailing system may recover from the error with minimum operator intervention, that is, the operator may be required to only remove the error producing mailpiece. A  motion control processor for an error producing mechanical module will report a fault to its corresponding mailpiece builder task and the error detector task.  Movement of at least the error producing mailpiece shall stop. The fault will be reported to the mailpiece builder tasks corresponding to the mechanical modules having no error condition. The mailing system shall suspend further processing of mailpieces upstream from the error producing mailpiece. For one category of errors, the mailing system will purge the error producing mailpiece from the error producing module without operator intervention. For the remaining category of errors, the operator will be required to remove at least the error producing mailpiece. State machines are then selected to perform system wide job recovery.

Title: Cardioverter/defibrillator shock timing function
Inventor: STOTTS LAWRENCE J
IPC: A61N1/39
Filed: 1995-09-19
Abstract: An implantable automatic cardioverter/defribrillator device for a cardiac patient is automatically responsive to sensing of electrical cardiac activity of the heart of a patient in which the device is implanted for detection and treatment of fibrillation. A prescribed electrical shock waveform regimen is generated as electrical defibrillation therapy for application to the heart in response to detection of fibrillation of the heart. A timing function circuit responds to the detection by timing the delivery of the generated prescribed electrical waveform regimen to be applied at a point in time at which the fibrillation ECG has substantially its highest amplitude and lowest frequency, as a point of high susceptibility to reversion to sinus rhythm upon application of a shock, and with low defibrillation threshold, to enhance the probability of successful defibrillation, and to synchronize the shock delivery to this sensed intracardiac event.

Title: Methods and means for determining the female fertile period
Inventor: MARCH STEVEN C
IPC: G06F19/00
Filed: 1994-12-16
Abstract: Provided is a highly reliable method to predict the beginning and/or ending of the fertile period for a female for each menstrual cycle. The methods and means provided advantageously address the day-to-day, cycle-to-cycle, and women-to-women variability in fertility hormone levels by analyzing the measurements of serial hormone concentrations in the midst of daily hormonal variations to determine when an actual and significant increase in the concentration of the monitored hormone has begun. Thus the present disclosure is directed to a method that combines existing hormone assay methods with calculation procedures to optimize the predictive values of daily hormonal changes. In this way a reliable and useful prediction of the fertile period is achieved with the concomitant assurance that the beginning and/or end of the fertile period has been reached so that such declarations are sufficient to provide both fertility enhancement and contraceptive utility.

Title: Thermal shield for a gas turbine combustion chamber
Inventor: SCHMID ACHIM
IPC: F23R3/28
Filed: 1995-07-17
Abstract: A heat shield for the head area of a combustion chamber has as usual a through-hole for the burner. A continuous collar with air passage holes projects from the back side of the heat shield at the edge of the through-hole.   Cooling air can flow through the holes into a ring-shaped channel arranged between the heat shield and the burner, then into the combustion chamber. This cool air flow lies as a cool air film on the surface of the heat shield. For that purpose, the cool air flow or cool air film swirls in the same direction as the combustion air supplied through the burner. To generate this swirling motion, the air passage holes in the collar are inclined in the radial direction. The heat shield is further provided with appropriate inclined effusion holes.
