Publication number: 20180150619Abstract: Systems and methods are provided for piecewise encryption of Page Description Language (PDL) print jobs. One embodiment is a method that includes receiving a Page Description Language (PDL) print job at a printer, wherein the print job includes segments of PDL content, and includes unencrypted PDL content. For each of the segments within the print job, the method includes detecting an identifier (ID) for the segment, correlating the ID with an encryption key stored at the printer, and decrypting the segment at the printer via the encryption key. The method further includes printing the print job, including each segment that has been decrypted.Type: ApplicationFiled: November 28, 2016Publication date: May 31, 2018Applicant: Ricoh Company, Ltd.Inventors: John Barker Condon, Reinhard Heinrich Hohensee, Harry Reese Lewis

Patent number: 7753887Abstract: A catheter insertion device is provided that includes an insertion needle that is retractable into the device after use to prevent exposure to the contaminated needle. The needle retainer releasably retains the needle in an extended position against the bias of the biasing element. When the catheter is removed from the insertion device, the needle retainer automatically releases the needle, which is propelled rearwardly into the device. A device for inserting a guide wire into a patient is also provided. The device includes an insertion needle that is retractable into the housing of the device after use. A needle retainer releasably retains the needle in an extended position against the bias of the biasing element. After the guide wire is inserted into the patient, the needle retainer allows the needle to be released, so that the needle is retracted into the device.Type: GrantFiled: March 28, 2003Date of Patent: July 13, 2010Assignee: MDC Investment Holdings, Inc.Inventors: Michael J.

Patent number: 7524306Abstract: A catheter insertion device is provided for inserting an over-the-needle catheter. The device includes an insertion needle that is retractable into the housing of the device after use to prevent exposure to the contaminated needle. A needle retainer releasably retains the needle in an extended position against the rearward bias of the biasing element. The needle retainer engages the hub of the catheter so that when the catheter is removed from the insertion device, the needle retainer automatically releases the needle. The biasing element then propels the needle rearwardly into the housing of the device. The device further allows the operator to intervene to delay retraction if desired.Type: GrantFiled: December 3, 2003Date of Patent: April 28, 2009Assignee: MDC Investment Holdings, Inc.Inventors: Michael J. Botich, Thor R. Halseth, John Barker
