Abstract: Fluid reservoir systems are disclosed herein. According to some embodiments, the present technology includes a reservoir defining a cavity and a plunger slidably received within the cavity. The plunger includes a vial interface, a plunger rod extending distally from the vial interface, and a needle extending longitudinally through the plunger rod. The needle has an inlet end at the vial interface and an outlet end proximate a distal portion of the plunger rod. When an outlet end of a vial of fluid medication is coupled to the vial interface, the needle extends through a septum of the vial such that the inlet end of the needle is disposed within the vial. When the plunger is fluidly coupled to the vial, proximal movement of the plunger and vial relative to the reservoir draws the fluid medication out of the vial, through the needle, and into the interior region of the reservoir.

Abstract: A ball striking device, such as a golf club head, has a face with a striking surface configured for striking a ball where the face has multiple thickness regions. The face has a center region, an upper region, a lower region, a toe region, and a heel region. The upper and lower regions have a ramped thickness extending from a center region to an upper and lower edge of the face. The heel and toe regions have a constant face thickness and have a thickness less than the other regions. Additionally, the club head body has a flange where the face is welded to the club head body.

Abstract: A medicine injection pen includes a body, a drive member, a cartridge housing, and a medicine cartridge retained within the cartridge housing. The drive member is configured to move relative to the body and the medicine cartridge defines an interior volume configured to retain a liquid medicine. The drive member is configured to translate a piston within the interior volume toward a dispensing end of the medicine cartridge to dispense at least some of the liquid medicine. The medicine cartridge also includes an insertion port configured to receive a medicine dispensing element therethrough for dispensing a liquid medicine into the interior volume to replace at least some of the liquid medicine dispensed through the dispensing end. Dispensing of the liquid medicine into the interior volume of the medicine cartridge applies a fluid pressure to the piston to translate the piston away from the dispensing end of the medicine cartridge.
