Patent number: 9516886Abstract: An animal stunning apparatus for inducing unconsciousness and insensibility of a live subject animal includes an applicator for contacting an application point on the live subject animal's head and couples microwave radiation to the head. A microwave generator generates microwave energy of a suitable power level and frequency, and a waveguide directs the microwave radiation to the applicator. An auto-tuner in the waveguide uses a directional coupler to detect forward and reflected power and to tune in real time the impedance for matching the load and optimize effective power transfer. A switch discontinues the application of microwave radiation that is heating the frontal portion of the brain after a period of time sufficient to induce the unconsciousness and insensibility. Methods for inducing rapid unconsciousness and insensibility in an animal include application of microwave radiation.Type: GrantFiled: November 4, 2013Date of Patent: December 13, 2016Assignee: Wagstaff Food Services Pty LtdInventors: James Henry Ralph, David William Mclean

Patent number: 8894474Abstract: Disclosed are an animal stunning apparatus and method for inducing rapid unconsciousness and insensibility. The apparatus includes a stunning station wherein a live animal is confined and an applicator contacts an application point on the animal's head overlying a frontal portion of the brain and couples microwave radiation to the head. A microwave generator generates microwave energy of suitable power and frequency, and a waveguide directs microwave radiation to the applicator. An auto-tuner in the waveguide uses a directional coupler to detect forward and reflected power and to tune in real time the impedance for matching the load and optimizing effective power transfer. A switch discontinues the application of microwave radiation heating of the frontal portion induce unconsciousness and insensibility. The period may be sufficient only to rapidly induce insensibility, and insufficient for the insensibility induced to be irreversible, or cause significant heating of deeper brain tissues.Type: GrantFiled: November 4, 2013Date of Patent: November 25, 2014Assignee: Wagstaff Food Services Pty LtdInventors: James Henry Ralph, David William McLean

Publication number: 20130324023Abstract: Described are animal stunning apparatus and methods for inducing rapid unconsciousness and insensibility. The apparatus includes a stunning station in which a live subject animal is located in a confined position and an applicator contacts an application point on the live subject animal's head immediately overlying a frontal portion of the animal's brain and couples microwave radiation to the head. A microwave generator generates microwave energy of a suitable power level and frequency, and a waveguide directs the microwave radiation to the applicator. A switch discontinues the application of microwave radiation effecting heating of the frontal portion of the brain after a period of time sufficient to have raised the temperature of the frontal portion of the brain of the subject animal to thereby induce the unconsciousness and insensibility.Type: ApplicationFiled: August 2, 2013Publication date: December 5, 2013Applicant: WAGSTAFF FOOD SERVICES PTY LTDInventors: James Henry Ralph, Jeffrey Stewart Owen, Alison Holdhus Small, David William McLean, Daniel John Gailer
