Abstract: Disclosed is a lid for a drinking cup with a detachable headband. The lid is removably securable to a drinking cup to prevent or minimize spills. A wearable headband attaches to the lid, frictionally secured between at least two protrusions extending upwardly from the top surface of the lid. The headband is attached to the lid by snapping it into place between the two protrusions and can be detached from the lid for wearing by a user. A recess may be formed in the lid between the protrusions so that an upper surface of the headband may extend generally flush with the upper surface of the lid.

Abstract: Operator controlled devices in the form of hand operated instruments in which a ring worn by an operator is configured to be insertable into a recess in a hand holdable portion of the instrument. The recess includes a fixed contact configuration that is engagable by a non-magnetic bridging contactor on an outer peripheral face of the ring, so that the instrument becomes operational when the contactor is inserted into the recess and engages the fixed contact configuration.
