  • Patent number: 11372703
    Abstract: A memory controller receives, via a first interface, a first read request requesting a requested data granule. Based on receipt of the first read request, the memory controller transmits, via a second interface, a second read request to initiate access of the requested data granule from a system memory. Based on a determination to schedule accelerated data delivery and receipt by the memory controller of a data scheduling indication that indicates a timing of future delivery of the requested data granule, the memory controller requests, prior to receipt of the requested data granule, permission to transmit the requested data granule on the system interconnect fabric. Based on receipt of the requested data granule at the indicated timing and a grant of the permission to transmit, the memory controller initiates transmission of the requested data granule on the system interconnect fabric and transmits an error indication for the requested data granule.

  • Patent number: 9572938
    Abstract: An automatic injection device for providing a subcutaneous injection is disclosed. The device includes a syringe movably disposed in a housing and including a barrel portion, a needle and a bung for sealing the barrel portion. The device includes a plunger for moving the syringe towards a first open end of the housing such that the needle projects from the first end, and for subsequently applying pressure to the bung. The plunger includes a rod connected at a first end to the bung, a compressible expanded central portion, and a flange between a second end of the rod and the central portion. The device also includes a biasing mechanism for biasing the plunger towards the first open end of the housing, the biasing mechanism disposed about the second end of the rod between the flange and a second end of the housing.

  • Patent number: 9486584
    Abstract: A method for treating a disorder using an automatic injection device is disclosed. The device includes a syringe movably disposed in a housing and including a barrel portion, a needle and a bung for sealing the barrel portion. The device includes a syringe actuation component for moving the syringe towards a first open end of the housing such that the needle projects from the first end, and for subsequently applying pressure to the bung. The syringe actuation component includes a pressurizer, a rod comprising a compressible portion projecting therefrom, and a flange between a second end of the rod and the compressible portion. The device also includes a biasing mechanism for biasing the syringe actuation component towards the first open end of the housing, the biasing mechanism disposed about the second end of the rod between the flange and a second end of the housing.

  • Publication number: 20100160894
    Abstract: The invention provides an automatic injection device for providing a subcutaneous injection of a substance into a user, comprising: a housing having an open first end and a second end; a syringe movably disposed in the housing, the syringe including a barrel portion for holding the substance, a hollow needle in fluid communication with the barrel portion for ejecting the substance from the syringe, and a bung for sealing the barrel portion and selectively applying pressure to the substance to force the substance through the hollow needle; a plunger for first moving the syringe towards the first end such that the needle projects from the first end and subsequently applying pressure to the bung, the plunger including a rod connected at a first end to the bung, a compressible expanded central portion and a flange between a second end of the rod and the compressible expanded central portion; and a biasing mechanism for biasing the plunger towards the first open end of the housing, the biasing mechanism disposed a

  • Publication number: 20070299394
    Abstract: Apparatus for removing a needle assembly from an injecting device, the needle assembly comprising a needle holder portion and a needle portion secured to, or integral with, the needle holder portion, the needle assembly being attachable to the injecting device via the needle holder portion, the apparatus comprising a housing (2) having an opening (5, 10, 12) through which the needle assembly can enter the interior of the housing, wherein within the housing there is provided a receiving portion (20) which is arranged to receive the needle holder portion in such a way as to impede rotation of the needle holder portion with respect to the receiving portion, and wherein the opening is formed such that the needle portion can enter the housing and the needle holder portion can enter the receiving portion by means of a relative movement between the housing and the needle portion which relative movement is lateral with respect to the axis of the needle portion.

  • Publication number: 20060167413
    Abstract: A syringe (1) is moved bodily forward by a plunger (7) (after release of a spring 8) by acting through an O-ring pressing onto an enlarged head (16) of a syringe container (3), in order to expose the needle (5) of the syringe before the plunger acts on a plug (4) within the syringe to cause the liquid to be ejected through the needle. There is, therefore, a two-step movement of the plunger, firstly together with the syringe through the medium of the O-ring, and secondly within the syringe container to force the plug forward, when a ledge (12) on the syringe container (3) is arrested by a stop (14), whereupon the frictional force between the plunger and the O-ring is relieved so that the plunger slides forward through the O-ring.
