A dishwasher having a speed-controlled induction motor coupled to a pump to drive the pump during dishwasher operation. A motor controller is connected to the induction motor to control the speed of operation of the induction motor. A dishwasher controller is connected to the motor controller for sending signals to, and receiving signals from, the motor controller during operation to control the motor speed.

A Static Compression Device (SC device) for active, measurable compression of a fusion graft by the surgeon at the time of surgery is disclosed. The SC device is attachable to adjacent vertebral bodies or other pieces of bone and has a device that applies compressive force to the adjacent vertebral bodies or pieces of bone to assist fusion according to Wolff's law.

The SC device allows the surgeon the ability to compress a segment, measure the applied compression, and lock the segment in the compressed position. In one embodiment of the invention, the pressure is applied to the SC device through a compression device that applies a desired and measurable amount of force. In this embodiment, the combination of the SC device with a pressure applying and measuring device allows the surgeon more control over the force applied to a cervical, thoracic or lumbar implant than has previously been available. In the preferred embodiment, the SC device compresses two or more adjacent vertebrae across an adjacent bone graft to facilitate fusion of these vertebrae to treat pain produced by pressure from the disks between such vertebrae bulging and resulting in contact with and pressure on the spinal cord and adjacent nerve roots. In other embodiments, the SC device may be used to apply measurable compression across any type of bony interface (e.g. fractures) to facilitate union.
