  • Publication number: 20180150619
    Abstract: 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.

  • Patent number: 9903930
    Abstract: The present invention provides a method and system to reduce the problem of signal dropout in data acquired using gradient-echo and asymmetric spin-echo magnetic resonance techniques, caused by linear susceptibility gradients in the direction of slice-selection. Specifically an algorithm is used to determine the optimal parameters of a tailored radiofrequency pulse along with the accompanying slice-selection and slice-refocusing gradients to correct this signal dropout.

  • Publication number: 20110248418
    Abstract: A moulding machine (10) comprises a moulding station (20). The moulding station (20) comprises a support (70) and an insulated enclosure (30). The insulated enclosure (30) has an open able aperture (40). The moulding station (20) is controllable such that the support (70) can rotate the insulated enclosure (30) between a filling position where the open able aperture (40) is upwardly open and an emptying position where the open able aperture (40) is downwardly open. A mould (50) is placed completely within the insulated enclosure (30). The mould (50) includes an open able entrance. The insulated enclosure (30) includes a heat source (80) for heating the external surfaces of the mould. In use, a first powdered plastic to form a shell of the moulding is formed into an outer skin coated on the internal surfaces of the mould. A second material is then formed into an inner skin on the inside surfaces of the outer skin. The moulding is then heated to cause the inner skin to form an expanded core.

  • Patent number: 7753887
    Abstract: 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.

  • Patent number: 7527607
    Abstract: A safety needle-bearing medical advice (10) is provided. Specifically, a safety device for injecting medicinal fluid into a patient is provided. The device comprises a hollow housing (20), a needle assembly (40) and a plunger (30). The needle assembly (40) releasably retains a needle (43) in an extended position in which the sharpened tip of the needle is exposed for use. At the end of an injection stroke, the plunger (30) engages the needle assembly (40), such that the needle (43) is released and retracted into a cavity (38) within the plunger. The device (10) includes structure for reducing the dead-space volume, which represents the amount a fluid remaining in the device at the end of an injection stroke. In addition, preferably the device (10) includes structure for minimizing the volume of potential air bubbles trapped in the medicinal fluid prior to an injection.

  • Patent number: 7524306
    Abstract: 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.
