Abstract: A motor-driven dental device has a motor control that is responsive to a load placed upon the motor. More specifically, the invention relates to a dental device having motor that drives a tool, wherein the tool is activated or otherwise controlled in response to a load placed upon the motor through the tool, such as by touching the tool to a surface. The tool may also be controlled by the sustenance, over a predetermined time period, of an increase or decrease in motor current beyond a predetermined hysteresis current threshold. The motor may be an electric motor, a rotary electric motor, and air driven motor, an ultrasonic device or the like.

Abstract: A hard-wired and wireless system for operating a dental or medical treatment apparatus is provided. The system includes a footswitch device and a dental/medical base unit, each having a communication element for transmitting and receiving signals. The footswitch and base unit are each programmed to have an initial identification address Then, the footswitch and base unit are reprogrammed to know the identification address of the other. The footswitch and base unit can be reprogrammed in the field by the end user. Subsequent communications between the footswitch and base unit include both identification addresses. The footswitch includes two switches that are activated by depressing the upper cover of the footswitch to a first position and second position respectively. The footswitch is particularly suitable for operating an ultrasonic dental scaler.

Abstract: An electrical connector (20) for mounting to a printed circuit board (24) includes a boardlock (22) secured thereto by an interference fit. The boardlock (22) has a first portion (58) including means for securing the boardlock (22) to the connector housing (26) and a second portion (68). The second portion (68) comprises spring means (72,74) extending from the first portion (58) to an end (80) beyond the mounting face (30) for reception in a boardlock receiving aperture (56) in the printed circuit board (24). The spring means (72,74) have a slot (70) therebetween and barb means (84) thereon with the barb means (84) positioned along the spring means (72,74) between the first portion (58) and the end (80) to engage wall means (92) of the boardlock receiving aperture (56).
