20100113924AUTOMATICALLY SUPPLYING A PRESSURIZING UNIT OF A MEDICAL INJECTION DEVICE WITH FLUID - In general, this disclosure relates to techniques for automatically supplying a pressurizing unit (e.g., syringe) that is used with a powered medical fluid injection device with fluid. An example method performed by the medical fluid injection device includes obtaining operational state information of the medical fluid injection device, wherein the operational state information includes information other than a fluid delivery amount for a subsequent injection procedure. The example method further includes using the operational state information to determine whether the powered medical fluid injection device permits a fluid replenishment operation for the pressurizing unit. If the fluid replenishment operation is permitted, the method further includes automatically supplying the pressurizing unit with an amount of medical fluid. If the device includes multiple pressurizing units, the device may initiate an automatic fluid replenishment procedure for one or more of the pressurizing units during operation.05-06-2010

20090149743Medical Fluid Injection System - One embodiment provides a method of using contextual lighting to assist a user of a medical fluid injection system. In this embodiment, the method includes providing a lighted display in proximity to a component of the injection system during setup of the medical fluid injection system. If the user has properly performed a setup function that is associated with the component of the injection system, the method further comprises providing a first visual indication on the lighted display. If the user has not properly performed the setup function that is associated with the component of the injection system, the method further comprises providing a second visual indication on the lighted display.06-11-2009
20100130935APPARATUS AND METHODS FOR FLUID PRESSURIZING UNITS OF INJECTION SYSTEMS - An injection system includes a syringe, which preferably includes larger and smaller inner diameters, and a plunger. A wiper sidewall of the plunger defines a cavity, into which a plunger shaft of the system is inserted, for moving the plunger, within the syringe, for fluid injection. The plunger includes a feature for engaging the shaft, and the sidewall preferably includes a expandable-contractible portion, in which the feature is formed. When the plunger is initially mounted within the larger inner diameter of the syringe, the portion of the sidewall is expanded and the feature of the plunger does not operably engage the inserted shaft. When the shaft moves the plunger into the smaller inner diameter of the syringe, the portion of the sidewall contracts and the feature operably engages the shaft. An optional deformable end wall of the plunger may be spaced apart from a distal terminal end of the inserted shaft.05-27-2010
20100331779Method and System for Removing Air from a Flow Path of a Fluid Injection Device - A method of removing air from a flow path of a medical fluid injection system is described. An exemplary method performed by the medical fluid injection device includes delivering a first amount of fluid to a fluid flow path, isolating fluid flow along the flow path, forming a vacuum condition upstream of the fluid isolation, re-establishing fluid communications along the flow path, and delivering a second amount of fluid to the flow path.12-30-2010

20100265667PORTABLE ASSEMBLY HAVING A SUBSCRIBER IDENTIFICATION MODULE - An electrical assembly comprises a housing, where the housing has an inner housing and a removable outer housing removably connected to the inner housing. A first connector portion is secured to the inner housing. The first connector portion comprises a dielectric body and connector terminals. A subscriber identification module is supported by the inner housing. The subscriber identification module has device terminals. A group of conductors or a conductor assembly supports an electrical connection of the connector terminals to the device terminals. A holder retains the subscriber identification module with respect to the inner housing.10-21-2010
20100265672PORTABLE ASSEMBLY HAVING A SUBSCRIBER IDENTIFICATION MODULE - The assembly has a subscriber identification module comprising a housing with a recess disposed in the housing. An electrical connector portion is secured to the housing. The connector portion comprises a dielectric body and connector terminals. A subscriber identification module is housed in the housing, where the subscriber identification module has device terminals. A conductor or flexible substrate electrically connects the connector terminals to the device terminals. A protective filler overlies the subscriber identification module and at least part of the conductor or the flexible substrate.10-21-2010
20100265673PORTABLE ASSEMBLY HAVING A SUBSCRIBER IDENTIFICATION MODULE - An electrical assembly comprises a housing having a frame portion. A substrate has a first side and a second side opposite the first side. A subscriber identification module is mounted to a first side of the substrate and has device terminals. A first connector portion is secured to the second side of the substrate and has connector terminals. A retainer is associated with an interior of the frame portion. The retainer retains at least one of the substrate and the first connector portion. Conductive (e.g., conductive vias or through-holes) in the substrate connect the connector terminals to the device terminals.10-21-2010
20100265674PORTABLE ASSEMBLY HAVING A SUBSCRIBER IDENTIFICATION MODULE - In accordance with one embodiment, an electrical assembly comprises a housing having a recess in the housing. A first connector portion is securable to the housing. The connector portion comprises a dielectric body and connector terminals. A subscriber identification module is located in or mounted in the housing and has device terminals. A substrate comprises a first section that intersects at an angle a second section. The first section comprises first conductive traces electrically connected to the device terminals. The second section comprises second conductive traces electrically connected to the connector terminals. Conductors are electrically connected to the first conductive traces and the second conductive traces.10-21-2010
