The XINA Delta (xd) compression format is a simple, high performance format for compression and decompression of a list of numeric values into a string. The compression is most efficient for data sets with frequently repeated values, or predictable value itera...

WRP run-time Run-time is calculated by measuring from the time the WRP speed exceeds 5400 RPM until it returns below 5400 RPM. WRP Cycles A cycle is an Start/Stop pair. A start is anytime the WRP RPM reaches at leat 5400 RPM. A stop is each time the WRP RPM cr...

HCV Cycles One cycle of the hCV include an HCV open and an HCV close. An HCV open is defined by completing at least 50 positive raw hall counts by monitoring the mnemominc HCV1_HALL_POSITION_COUNTS. An HCV close is counted when the HCV changes by at leat 100 n...

DraMS has two filaments, filament A and filament B. On Time Filament A and Filament B on time are determined by measuring the amount of time that HFB_FIL_ON_A or HFB_FIL_ON_B are 1. Cycles Filament A and Filament B cycles are determined by counting the number ...

On Time EM A and EM B on times are determined by summing the on times for all scans, and then looking for any time when the EMs were constantly on outside of scanning. CTL sequences are examined to determine the on time for individual scans. In order to avoid ...

Laser Shots Laser shots are determined by summing the number of pulses in the LEU.MAX_HKHS packets and LEU.HKHS packets. Each of these packets is generated for each laser shot. Whether we receive the MAX_HKHS packet or the HKHS packet depends on the LEU settin...

GPS Valve Cycles GPS valves are the microvalves and GC valves in the manifolds. The high- conductance valve (HCV) and the multi-function valve (MFV) are documented in another entry. Valve cycles are determined by examining the message log and counting the numb...

MFV Cycles Counts the number of times the Multifuntion Valve (MFV) has been opened. A cycle consists of an open and close. The valve transitions from open to closed when the MFV temperature transistion above 100C (TBC). It is considered closed when it transiti...
