Abstract: An electronic memory game system including a base unit, a plurality of triggers disposed on the base unit, a housing mounted to the base unit and extending over a portion of the base unit, a plurality of illumination devices disposed on the housing for displaying a memory challenge sequence, wherein the plurality of triggers are actuated to generate a memory response sequence to the memory challenge sequence, and/or a wireless communication device configured to communicate with a remote wireless communication device.

Abstract: An improved induction heating apparatus is provided for attaching membrane roofs. A top membrane layer is attached to attachment disks that hold sheets of thermal insulation to the top of roof substrates. The heating apparatus emits a magnetic field that raises the temperature of the disks and a heat-activated adhesive on top of the disks which, after cooling, becomes adhered to the bottom surface of the top membrane layer. The disks in turn are attached via fasteners to the substrate portion of the roof structure. The apparatus includes a set of bottom guides that allow a user to find the attachment disks mechanically, without actually seeing those disks beneath the top membrane layer. A fine locator circuit is provided, using a magnetic field, and the apparatus allows a user to stand upright while operating the apparatus.
