Abstract: A heat exchanger is characterized by having two or more fluid flow circuits, each formed by multiple small cross-section “micro-tubes” contained within a surrounding metal structure, or “metal matrix.” Its function is to efficiently transfer heat from one fluid to another in a highly compact assembly. Most any metal or metal alloy can be considered for the micro-tubes. The micro-tubes, while typically arranged in alternating layers of alternating flow circuits, may be organized in any number of arrangements including co-linear and at cross angles to provide for co-flow, counter flow and cross flow. The metal matrix, is provided in one embodiment by a metal or metal alloy powder consolidated in a hot isostatic pressing (HIP) process. This process also joins the tubes together and to the matrix itself, producing a monolithic structure.

Abstract: A photocopier apparatus includes a scanning module configured to scan an original document; a printing module configured to print a copy of the original document using output from the scanning module; and a media feed path configured to transport the original document and the copy to a single output receptacle.

Abstract: Substantially pure high pressure steam is produced within a high pressure heat exchanger. Heat for the high pressure heat exchanger is provided from an outlet of an oxy-fuel combustion gas generator which discharges a steam/CO2 mixture at high pressure and temperature. The gas generator combusts oxygen and hydrocarbon fuel and mixes with water which can include contaminates therein in the form of dissolved solids or hydrocarbons. A separator is typically provided downstream of the gas generator and upstream of the heat exchanger and the steam/CO2 mixture is discharged from the gas generator at saturation temperature. A water fraction of the steam/CO2 mixture is discharged from the separator along with dissolved solids in concentrated brine form. The water heated into steam by the heat exchanger can be at least partially water separated within a condenser downstream of the heat exchanger.

Abstract: A media wrapper for use in a printing device includes a first end, a second end, and a perforation disposed between the first and second ends, wherein the perforation is configured to split the media wrapper separating the first and second ends.

Abstract: A representative embodiment provides for a document printing apparatus having a print engine a print engine configured to print sheet media, and an output tray configured to receive printed sheet media from the print engine. The printing apparatus further includes a memory device, a processor, and a sheet media detector.

Abstract: Various systems, methods, and programs are provided that facilitate access to a secure application. In one embodiment, a method is provided that includes encrypting at least one authentication sequence in a computer system using a network identifier as an encryption key, and storing the encrypted at least one authentication sequence in a memory accessible to the computer system. Next, the encrypted at least one authentication sequence is decrypted using a second network identifier as a decryption key, the second network identifier is procured after storing the encrypted at least one authentication sequence. Thereafter, an expedited login task is performed to access the application with the at least one authentication sequence if the decryption of the at least one authentication sequence is successful.

Abstract: A method of powering up a printing device having a component that employs a warm-up operation, the method including, upon receiving power to the printing device, detecting delay indicia, and selectively delaying the warm-up operation based on the detected delay indicia.

Abstract: A printing device is provided that includes a housing having a media path therethrough. The printing device includes at least one sensor for detecting when a media jam occurs in the media path. At least one indicator is operatively associated with a processor to provide a series of indications that can be used to locate the media jam.

Abstract: A printing device can include a capacitive monitoring system to monitor the amount of print medium (e.g., paper) available in the printing device. The capacitive monitor includes conductive plates above and below the supply of print medium. With the print medium acting as a dielectric element, the capacitance of the system will change as print medium is removed from the supply. This change in capacitance can be used to monitor the supply of print medium in the printing device.

Abstract: A printer error is detected and logged in an error log. If the same printer error has occurred within a predetermined time period, an error message is generated on the printer's control panel and a network administrator is notified of the printer errors. If the same printer error has not occurred within the predetermined time period, the printer is rebooted. If the same printer error has occurred a predetermined number of consecutive times, an error message is generated on the printer's control panel and a network administrator is notified of the printer errors. If the same printer error has not occurred a predetermined number of times, the printer is rebooted.
