Patent number: 11191902Abstract: A combination plunger, a mixing device and a mixing syringe including the same are provided. The mixing syringe includes concentric outer and inner barrels that form an outer chamber, the inner barrel having an inner chamber. The combination plunger includes a mixing plunger and a delivery plunger and a biasing means. The mixing plunger is slidably located in the outer chamber and translated by coordinated depression of the delivery plunger to transfer a first substance from the outer chamber to mix with a second substance in the inner chamber. After the mixing stage is complete, the delivery plunger is disengaged from the mixing plunger and permitted, such as by rotation, to be further depressed in the axial direction to deliver fluid contents of the mixing syringe to a recipient. The mixing syringe needle is then retracted as result of engagement by the delivery plunger and activation of the biasing means.Type: GrantFiled: October 16, 2018Date of Patent: December 7, 2021Assignee: UNL HOLDINGS LLCInventors: Peter J. Dungar, Molly M. Weaver, Philip A. Weaver, Katlin M. Lumme, Robert E. Johannesson

Patent number: 10875499Abstract: A method is disclosed that is implemented by a computing device in a vehicle. Identifying information is obtained from an occupant of the vehicle via an input device operatively connected to the computing device. If the computing device has connectivity to a remote authentication server, the computing device transmits a request to the authentication server, and controls whether full operation of the vehicle is enabled or disabled based on a response from the remote authentication server. The request includes the identifying information and a vehicle identifier of the vehicle, and requests that the authentication server determine, based on the identifying information and the vehicle identifier, whether the occupant is authorized to operate the vehicle. If the computing device lacks connectivity to the remote authentication server, full operation of the vehicle is temporarily enabled until the computing device has connectivity to the remote authentication server.Type: GrantFiled: September 18, 2015Date of Patent: December 29, 2020Inventors: Michael J. Mouser, Philip A. Weaver, Donald J. Finney

Patent number: 10279121Abstract: A mixing device and a retractable syringe comprising same are provided. The mixing device comprises concentric outer and inner barrels that form an outer chamber, the inner barrel having an inner chamber. A mixing plunger is slidably located in the outer chamber. A seal located in the outer chamber is capable of axial movement, in response to depression of the mixing plunger, from a first position in sealing engagement with one or more apertures in the inner barrel to a second position intermediate the apertures and vents in the outer barrel. This allows depression of the mixing plunger to force a first substance from the outer chamber through the apertures to mix with a second substance in the inner chamber. The mixed substance in the inner barrel is then delivered by the syringe with subsequent needle retraction.Type: GrantFiled: October 22, 2015Date of Patent: May 7, 2019Assignee: UNL Holdings LLCInventors: Ramin Mojdehbakhsh, Peter J. Dungar, Ashley W. Palmer, Robert E. Johannesson, Philip A. Weaver, Aaron M. Weir

Patent number: 10166336Abstract: An actuation mechanism for an automatic injector includes a first actuation spring, a first actuation pill, a second actuation spring, and a second actuation pill. In an initial configuration the first actuation spring resides in a compressed, energized state substantially within an upper portion of first actuation pill and the second actuation spring resides in a compressed, energized state between the first actuation pill and the second actuation pill. An automatic injector includes a housing, an activation mechanism, an actuation mechanism, and a syringe cartridge having a plunger and a needle assembly. A retractable syringe may be utilized as a syringe cartridge, such as a prefilled retractable syringe with integrated safety features which retract the needle after use. The automatic injector may be utilized to inject the needle, deliver a drug treatment, and activate retraction of the needle. Methods of assembly and operation are also provided.Type: GrantFiled: July 11, 2014Date of Patent: January 1, 2019Assignee: UNL Holdings LLCInventors: Katlin M. Lumme, Philip A.
