Abstract: A digital state device may include a first circuit terminal that obtains a clock signal from a first integrated circuit. The digital state device may further include a second circuit terminal that transmits the clock signal to a second integrated circuit. The digital state device may further include digital logic circuitry coupled to the first circuit terminal and the second circuit terminal. In response to obtaining an in-band notification signal in reverse of the clock signal and from the second integrated circuit, the digital logic circuitry sets the clock signal to a first predetermined value. In response to the digital logic circuitry determining that the clock signal exceeds a predetermined amount of time at the first predetermined value, the digital logic circuitry sets the clock signal to a second predetermined value that is different from the first predetermined value.

Abstract: A plug for use in a downhole tool collar allows a seal between the inside and outside of the collar. The plug provides an electromagnetically transparent window through which the signals from the measurement device may propagate to or from the surrounding formation. The plug assembly includes an inner retainer, an outer retainer, and a plug. The inner retainer may be inserted into the inside of a slot formed in the collar. The inner retainer may have a concave inner surface to match the cylindrical inner surface of the collar. Likewise, the outer collar may be inserted into the outside of the slot, and may have a convex outer surface to match the cylindrical outer surface of the collar. The plug may fit into slots in the inner and outer retainers and be held in place within the slot.

Abstract: Provided herein are systems and methods for removing halogens and sulfur from used oil. The used oil is heated and aerated, followed by rapid vaporization and cooling. The cooled oil is then subjected to an electrical field before being filtered.

Abstract: A system including a housing having an upper end in fluid communication with a source of pressurized fluid and a lower end releasably coupled to an expandable tubular. A piston is disposed within and sealingly engaged with the housing. An expansion cone is coupled to the piston and is operable to radially expand the expandable tubular as it moves longitudinally therethrough. A pressure chamber is disposed within the housing and defined by the piston and the expansion cone. A first pressure relief port is disposed within the housing and is operable to allow fluid communication between the pressure chamber and an annulus external to the housing. A second pressure relief port is disposed within the expansion cone and is operable to allow fluid communication between the pressure chamber and a portion of the expandable tubular below the expansion cone.

Abstract: A multifunction printer includes a printing apparatus including: a printing device for printing on recording medium; a media advance system for moving the recording medium into position to be printed on by the printing device; and a scanning apparatus including: a platen including: a transparent portion; a first surface for supporting items to be scanned; a second surface opposite the first surface; a scan bar assembly disposed proximate the second surface of the platen; a frame including an uppermost surface that is disposed proximate to the second surface of the platen; and a lid disposed proximate the first surface of the platen, wherein a distance between the lid and the first surface of the platen is less than a distance between the lid and the frame when the lid is closed.

Abstract: A method of making and using a printer comprising a duplexing unit that pivots along a horizontal plane for media path access. The duplexing unit does not contain any motor driven rollers for moving a media sheet therethrough. The duplexing unit's vertical axis hinge allows the duplexing unit to swing open and closed horizontally.

Abstract: A method of making an ink cartridge by forming an ink chamber, an air accumulation chamber, and a cap including a vent hole is disclosed. The cap is affixed at a first end of the air accumulation chamber and a one way valve is disposed at the vent hole for preventing gas from entering the air accumulation chamber through the vent hole when a pressure in the air accumulation chamber is less than a cracking pressure of the one-way valve. A neck region narrower than the ink chamber and the air accumulation chamber is formed for fluidically connecting the ink chamber and the air accumulation chamber. A mass is placed within the air accumulation chamber, the mass having a dimension smaller than an interior dimension of the air accumulation chamber such that the mass is movable between the first end and a second end of the air accumulation chamber.
