摘要： An analog encoder of one embodiment of the invention is disclosed that includes an input mechanism, a digital signal processing mechanism, and an output mechanism. The input mechanism is to receive and digitize different analog encoder signals. The digital signal processing mechanism is to generate inverse analog encoder signals from the different analog encoder signals, and to apply dynamically changeable gain and offset corrections in real-time. The output mechanism is to generate digital quadrature signals from crossing points among the analog encoder signals and the inverse analog encoder signals, and a position value based on a direction of the digital quadrature signals for external access.

摘要： An ink supply for an inkjet printer is provided with a main reservoir, which is typically maintained at ambient pressure. The main reservoir, which has flexible side walls supported by a rigid frame, is coupled to a variable volume chamber via a check valve which allows the flow of ink from the reservoir to the chamber and limits the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet which is normally closed to prevent the flow of ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer.

摘要： One aspect of the present invention is a removable ink supply for forming a fluid connection with a fluid inlet of an ink-jet printer into which the ink supply can be installed. The ink-jet printer has a fluid conduit for supplying liquid ink to an ink-jet printhead. The removable ink supply includes a quantity of liquid ink and a fluid outlet. The fluid outlet includes (i) a hollow boss having a first end in fluid communication with the quantity of liquid ink, a neck formed in a second end of the boss, the neck defining a scaling surface and an opening; (ii) a sealing member positioned within the boss, the sealing member being movable between a first position in which the sealing member seals the opening and a second position in which liquid ink can flow through the boss opening; and (iii) a biasing structure for biasing the sealing member toward the first position. The ink supply is adapted for installation in the fluid inlet of the ink-jet printer. Upon installation the sealing member is engaged and displaced from the first position to the second position such that the sealing surface engages against a structure of the fluid inlet to create an ink seal.

摘要： In one embodiment, a method of operating a permanent magnet direct current (PMDC) motor in a printer has been developed. The method includes identifying that a temperature of the PMDC motor exceeds an operating temperature of the motor without the use of a direct temperature sensor. The PMDC motor operates at a reduced printing rate to prevent the motor from overheating.
