Abstract: A handheld needle incinerator is self-contained within a portable housing and includes a guideway designed to guide the external walls of a diabetes pen-type injector into the incinerating chamber. Two spaced electrodes are simultaneously engaged by the needle to complete an electrical circuit and cause needle incineration. One electrode is dome-shaped and protrudes through an opening in the other electrode. Surrounding the opening in the other electrode is an annular generally conical surface designed to act like a ramp and lead the end of the needle toward the dome-shaped electrode to cause completion of the electrical circuit.

Abstract: A self-sanitizing toilet seat cleaning apparatus includes a seat in the shape of a generally circular ring that is rotatably mounted above the toilet bowl and includes a gear on its underside meshing with a pinion gear attached to the drive shaft of a drive motor for the seat. An arm extends over a rear portion of the seat and includes flow passages that convey a disinfectant on top of the seat, under the seat, and into the toilet bowl. Under the arm, a wiper is provided that wipes the top surface of the seat as it rotates. The toilet includes a weight sensor that stops rotation of the seat if a person is sitting on it and a proximity sensor to activate flushing of the toilet and rotation and disinfecting of the seat and bowl.
