  • Publication number: 20230390503
    Abstract: A medication delivery device is provided with a stainless steel needle or cannula where the patient end of the needle or cannula has a protective outer layer over the surface of the needle or cannula. The protective outer layer has a thickness and is oriented to prevent or minimize contact of the tissue of the patient with the stainless steel to prevent or inhibit allergic reactions by the tissue contact with the nickel in the stainless steel. The protective outer layer can be a metal coating of a non-allergenic metal, such as gold, or other coating material that is able to cover the exposed surface of the needle to prevent direct contact of the stainless steel with the patient.

  • Publication number: 20220280728
    Abstract: An improved flow sensor (104) is provided to enable accurate dose measurements to be made with little or no sensor calibration due to highly accurate flow channel cross section. The flow channel is formed as a metal tube (1301). A sensor window (1304) is formed in the side wall of the metal tube (1301), and the flow sensor (1200) is mounted in the sensor window. A flow manifold is formed around the metal flow channel.

  • Patent number: 11413432
    Abstract: A self-slitting open lumen cannula may be used with catheter adapters to reduce manufacturing complexity and costs, as well as improve the safety of the catheter adapters against fluid leakage. The open lumen cannula may also include one or more notches to facilitate flashback visualization. The catheter adapters may further include a catheter adapter body formed of a compliant material that houses one or more compression resistant septa with at least one lumen formed by the proximal end of the needle during a self-slitting process as the catheter adapter is assembled. The compression resistant septum may also be coupled to a compression cap that imparts a radial compression force on the one or more compression resistant septa such that the at least one lumen narrows and seals when the cannula is removed.

  • Patent number: 10207861
    Abstract: Packaging concepts include a product packaging (10) for a solid product block (14), in particular for a dispenser system. The packaging includes a wrapping (12) comprising a top (16), sides (20), and a bottom (18), forming a cavity with an opening (22) configured and arranged to receive the solid product block (14), a mesh (26) covering the opening (22) fluid-permeable, and a lid (28) attached removably to the mesh (26) in a closed position for sealing the opening (22) of the wrapping means (12). The product packaging (10) improves the safe handling of the solid product block (14).

  • Patent number: 8854936
    Abstract: Embodiments of optical disc drives are described that perform automatic forward sense calibration of write laser power using a sample and hold sampling strategy that is automatically determined based on an automatically selected write strategy. Embodiments of the described optical disc drive may be dynamically configured to support any optical disc media, any write mode, and any write strategy. The write strategies supported may include dynamically changing write speeds and/or write power levels across the respective optical media tracks. As the optical drive is automatically configured for a selected write media/write mode/write strategy, the sample and hold sampling delays used to control the sampling of a forward sense feedback signal are also automatically configured, thereby allowing each forward sense sampling point to be aligned with an area of the forward sense feedback signal that corresponds to a power level of interest and that avoids distortion in the feedback signal.

  • Patent number: 8395977
    Abstract: Aspects of the disclosure provide a method for power calibration. The method includes writing, using a power configuration, a second pattern over a first pattern on a rewritable storage medium. The first pattern includes at least a first symbol and a second symbol while the second pattern does not include the second symbol. Thus, the second symbol in the first pattern is erased according to the power configuration. Then, the method includes reading the rewritable storage medium to measure remaining amplitude of the second symbol in the first pattern.

  • Patent number: 7215616
    Abstract: Because of the reduced track pitch of DVD compared to that of CD, the running-OPC procedures (ROPC) currently used in CD-RW systems do not function well in recordable and rewritable DVD systems. The present invention proposes to use the reflected signal from the writing spot itself instead of the satellite spots used in the CD-RW running-OPC procedure. This is realized by sampling the RF-signal reflected from the writing spot at the high-reflective crystalline level. This sampled signal (?) is fed into a power control loop (a so-called ?-loop) to keep it at a constant level.
