Patent number: 10730687Abstract: An article dispensing apparatus includes a carousel and an upper casing with a dispensing face including a dispensing orifice through which the articles are dispensed. The carousel includes plural holding sections for holding the articles to be dispensed and is rotationally movable. A controller controls application of a force to cause the carousel to rotate relative to the dispensing face when an instruction to dispense an article is received. When the carousel is moved so that one of its holding sections having an article therein is aligned with the dispensing orifice, the article is allowed to be dispensed therethrough. A locking mechanism selectively engages the carousel to prevent any relative movement of the carousel when the article dispensing unit is not mounted on the main housing and disengages from the carousel to allow intended relative movement when the article dispensing unit is mounted on the main housing.Type: GrantFiled: October 16, 2014Date of Patent: August 4, 2020Assignee: RxCap Inc.Inventors: David MacVittie, Hale Kpetigo, Michael A.

Patent number: 6785994Abstract: The invention is a firearm safety indicator that is spring-loaded, thus enabling self-ejection when a firearm's bolt is actuated. To attain this, the indicator comprises a main body and cantilever spring body joined together. A peg extends perpendicularly from the main body. In use, the peg is positioned inside the firing chamber of a firearm through the ejection port. The main body covers the ejection port and the cantilever spring body is therefore compressed to attain proper positioning. The rifle's bolt is then used to engage and hold the peg in place. When actuated, the bolt releases the peg and the spring body is released, thrusting the indicator away from the firearm. Alternately, a metal spring may be utilized in the place of the cantilever spring body.Type: GrantFiled: June 17, 2003Date of Patent: September 7, 2004Inventor: Ned F. Christiansen
