  • METHODS AND APPARATUS FOR LOCALIZED TEMPERATURE CONTROL AND LEAKAGE PROTECTION IN A SERVER HOUSING
    Publication number: 20240357777
    Abstract: Methods and apparatus for localized temperature control and leakage protection in a server housing are disclosed. An example system includes interface circuitry, machine readable instructions, and at least one programmable circuit of a server disposable inside a portion of a server housing. The at least one programmable circuit are to at least one of instantiate or execute the machine readable instructions to identify a temperature of the server, determine a target temperature for a workload for the server, and control an actuator based on the temperature and the target temperature, the actuator to control a local flow rate of a coolant in the portion of the server housing.

  • Print process for duplex printing with alternate imaging order
    Patent number: 8919949
    Abstract: A method for performing duplex printing with improved throughput has been developed. The method includes forming an image of a back side of a first duplex page and an image of a front side of a second duplex page on an image receiving member. Two recording media sheets are serially passed through a nip to transfer the image of the first duplex page back side to a bare side of a recording media sheet that also bears the image of the front side of the first duplex page on an obverse side and to transfer the image of the second duplex page to a bare side of a recording media sheet that has not been previously printed.

  • Alternate imaging order for improved duplex throughput in a continuous print transfer printer
    Patent number: 8322812
    Abstract: A method/printer prints images on an “A” side of a first sheet of media and on an “A” side of a second sheet of media in a single full transfer rotation of a drum. The method then prints images on the B side of the first sheet and on an A side of a third sheet in a single full transfer rotation of the drum. Similarly, the method prints images on the B side of the second sheet and on an A side of a fourth sheet in a single full transfer rotation of the drum. This method then prints images on the B side of the third sheet and the B side of the fourth sheet in a single full transfer rotation of the drum.
