Abstract: A button for actuating a switch in a surgical handpiece. The button is sealed to a bezel, and the bezel is sealed to the handpiece. The button, bezel, and handpiece create a sealed enclosure surrounding the switch to prevent external substances from contacting the switch. Further, a control board for controlling the handpiece is embedded in a cable endcap instead of being housed within the handpiece.

Abstract: A system and method for more efficient cleaning and sterilizing of surgical handpieces by using a removable valve assembly. The valve assembly is removable to provide access to a first suction passageway and a second suction passageway for cleaning purposes. The valve assembly has a protrusion that engages with a handpiece to secure the assembly to the handpiece. The protrusion of the valve assembly may also be retracted into the valve assembly to allow the valve assembly to disengage the handpiece thereby allowing the valve assembly to be removed from the handpiece. The first suction passageway may also be removable.

Abstract: A system for enhanced sealing against intrusion of moisture and other contaminants for medical/dental handpieces having rotating or other moving elements driven by a motor within the handpiece. The enhanced sealing includes tandem seals on stepped diameters to provide additional flow pathway impediments. The tandem seals preferably include spring seals that are positioned in opposite directions to provide enhanced sealing against pressures in two different directions that occur during the pressurization and vacuum cycles of an autoclaving process. Additional enhancements include the use of annular sealing rings with x-shaped cross sections.

Abstract: An apparatus and method for motivating a consumer to promptly indicate an interest in purchasing a product and/or service over a computer network includes the steps of presenting an offer for sale of a product and/or service to the consumer over the computer network, concurrently presenting an incentive for purchasing the product and/or service to the consumer promptly over the computer network. The incentive is initially set to a predetermined maximum value and decreases over a period of time. Additional steps include indicating an interest to purchase the product and/or service by the consumer at a point in time during the period of time, and providing the consumer the current value of the incentive corresponding to the point in time at which the consumer indicated the interest.
