Abstract: A cutting accessory for use with a powered surgical handpiece includes an elongated shaft, a tissue working member, and a proximal section. The elongated shaft has proximal and distal ends, and a longitudinal axis. The working member is attached to the distal end of the shaft. The proximal section extends proximally from the distal end and includes a plurality of faces extending inwardly from an outer surface of the shaft. Each face has at least one shallow portion and is shaped to receive a clamping member. At least two of the faces are arranged linearly, extending along the shaft proximal section. A flat extends distally forward of the distalmost face, and is located a distance from the shaft longitudinal axis greater than the distance the shallow portions are located from the longitudinal axis and less than the distance the outer surface of the shaft is from the longitudinal axis.

Abstract: A motorized surgical handpiece with a chuck. Internal to the chuck are clamping members that releasably hold clamp the shaft of a cutting accessory to a drive shaft so the cutting accessory rotates upon the actuation of the motor. The chuck includes a collar with an opening through which the cutting accessory is inserted. The opening is non-circular in shape. When an accessory shaft with a cross sectional shape that matches the shape of the opening is inserted in the opening, the accessory shaft is appropriate aligned with the chuck clamping members.

Abstract: A system for determining a level of a liquid present in a storage container in an automobile is disclosed. The system has a liquid level sensor for determining a preliminary liquid level of the liquid stored in the storage container, an ignition key position sensor for determining an ignition position, a vehicle speed sensor for determining the automobile's speed, a transmission gear selection sensor for determining a transmission gear position of a transmission of the automobile, and a processor. The processor receives input signals from the liquid level sensor, ignition key position sensor, the vehicle speed sensor and the transmission gear selection sensor for calculating the level of the liquid in the storage container.
