Other aspects of these embodiments include specially designed and located alignment features of a fluid reservoir that engage specially designed and located alignment features of a chassis in sequence throughout the process of inserting the fluid reservoir into the chassis in order to facilitate simple and effective engagement.

Abstract: A method and system for the systematic evaluation and rating of technical equipment using a data processing device (20), which works together with at least one data memory (21) and has an input (22) and display device (23), in which, step-by-step for the particular technical equipment, at least one first data set having economically relevant input parameters and at least one second data set having technically relevant input parameters are detected and/or established. For each data set, through knowledge-based predetermined numerical and/or logical linkages and knowledge-based predetermined weighting factors specific to the equipment, the established input parameters are brought together into an economic evaluation parameter FIx and a technical evaluation parameter RIx, respectively, and from the established evaluation parameters, through knowledge-based predetermined numerical linkages and weighting factors, a single overall resulting evaluation parameter EIx is determined.

Abstract: A preferred method for identifying a type of abnormality in an insulation system of a power transformer comprises measuring dielectric losses in a section of the insulation system, calculating theoretical dielectric losses for the section based on the material properties, geometry, and temperature of the section, and generating a graphical representation of a percent difference between the measured and calculated dielectric losses. The preferred method also comprises comparing a shape of the graphical representation with a shape of one or more graphical representations of a percent difference between measured and theoretical dielectric losses in one or more other sections of insulation each known to have a specific type of abnormality.

Abstract: A cartridge comprises a pair of housing portions having an opening at a seam formed between the housing portions, a memory chip accessible via the opening to permit electrical contact to be made with the memory chip, and a protuberance projecting from one of the housing portions and welded to the other housing portion within a cavity of the other housing portion. Since a flash which is formed at the weld can spread towards the seam including in the vicinity of the opening, the protuberance and the cavity are mutually dimensioned to restrict the flash substantially to within the cavity. This prevents the flash from spreading into the seam and bulging outward at least in the vicinity of the opening, which could interfere with formation of the seam and making electrical contact with the memory chip.

Abstract: A method of filling an ink supply bag with a liquid ink, includes positioning the bag bottom end down and a top end up; flowing the liquid ink into the bag through an upper portion of the bag to fill the bag to a liquid level below the upper portion; squeezing the bag to raise the liquid level in the bag partway into the upper portion, and shaking the bag to cause any bubbles in the liquid ink in the bag to rise at least substantially to the liquid surface in the upper portion; and sealing the upper portion above and below the liquid level in the upper portion to trap a small quantity of liquid ink that includes the bubbles and a small quantity of air between the respective seals.

Abstract: An alternative ink/cleaner cartridge includes an egress snout from which an ink supply or a cleaner supply is discharged from the cartridge. The snout and a collar that mates with the snout are mutually configured to permit the collar to mate with the snout only when the collar is in any one of a number of allowable orientations, to provide an identification of an ink supply to be discharged from the cartridge. Alternatively, the snout mates with a cap in place of the collar to prevent a cleaner supply from being discharged from the cartridge.

Abstract: A system and method for detecting a registration mark associated with an object which provides improved resolution between matching and non-matching inputs. The registration mark represents a binary code sequence. Upon detecting a sequence of bits with a sensor, the detected sequence is provided to a code matching filter, which compares the detected sequence with the binary code sequence and produces a detection signal. The code matching filter increases a value of the detection signal for each matching pair of compared bits, and decreases the value of the detection signal for each non-matching pair of compared bits. In this manner, a penalty is assessed for mismatches. This results in a filter output having a high amplitude in response to a matching input, and a low amplitude for non-matching inputs. The system may sample the detected sequence of bits in such a manner as to avoid potential edge timing problems.

Abstract: A fitting is attached to a disposable ink supply bag and has an ink egress snout for discharging an ink supply from the bag. The fitting is configured to engage with a housing for the bag to permit the bag to be connected to the housing when the ink supply is to be discharged from the snout and to disengage from the housing to permit the bag to be disconnected from the housing in order to dispose of the bag when emptied.

Abstract: An ink cartridge includes an ink supply bag, a fitting attached to the bag and including an integral ink egress snout, and a pair of housing halves that contain the bag and at respective wall portions have opening halves that form a bottom opening for the snout when the housing halves are connected together. The fitting and only one of the wall portions each have mutually engageable members that engage to connect the fitting and the one wall portion to secure the bag within the housing half that includes the one wall portion. The housing half that includes another of the wall portions has stakes that are adhered to the engageable members of the fitting and/or the engageable members of the housing half that includes the one wall portion.

Abstract: A disposable ink assemblage intended for an ink cartridge includes an ink bag containing an ink supply, and an ink egress snout attached to the bag and from which the ink supply is to be discharged from the bag. The snout is configured to be received in a collar only when the collar is in any one of a number of allowable orientations, and to fix the collar relative to the snout in a selected one of the orientations in order that the fixed orientation of the collar may serve to identify the ink supply in the bag.

Abstract: An ink cartridge includes an ink egress snout from which an ink supply is discharged from the ink cartridge, and a collar that mates with the snout and can be arranged in any one of a number of allowable orientations to provide an identification of the ink supply. The snout and the collar are mutually configured to permit the collar to mate with the snout only when the collar is in any one of the orientations, whereby an identification of the ink supply can be provided simply by the collar mating with the snout.

Abstract: A system and method for detecting a registration mark representing a binary code sequence of N bits. A sensor is provided to output values indicating whether positive bits, negative bits, or no bits of the binary code sequence are detected. A sequence of N sensor values are provided to a code matching filter for comparison with the binary code sequence. The code matching filter increases a value of a detection signal for each sensor value which matches its corresponding bit, decreases the detection signal value for each sensor value which is complementary to its corresponding bit, and neither increases nor decreases the detection signal value in response to a sensor value indicating detection of no bit of the binary code sequence. When the binary code sequence is a Barker code, the code matching filter yields the ideal Barker auto-correlation function response whenever the binary code sequence is detected.
