An apparatus for providing medical treatment includes a tool portion configured to operate relative to bone tissue, a handle portion to operate the tool portion, and a nerve monitoring system to detect neural elements. The tool portion includes an insulated shaft comprised of an electrically conductive member and a non-insulated tip. The shaft carries an electrical signal to the non-insulated tip. The handle portion, which is removably and operably connected to the tool portion, incorporates an operating system to operate the tool portion. Additionally, the nerve monitoring system is linked to the tip and is operable to detect a neural element as a function of a characteristic of the electrical signal on the tip. Upon detection of a neural element, the nerve monitoring system provides a signal to the operating system of the handle portion directing the operating system change an operative mode of the tool portion.

A restaurant information system includes a point-of-sale (POS) device constructed and arranged for identifying a customer at a restaurant, an amount owed for food or other items purchased at the restaurant, a financial services provider, and a restaurant customer service of which the customer is a member. A network server is associated with the restaurant customer service, and is configured to access a personal customer file created by the customer. The POS device is configured to prompt and receive a customer entry including a review or other comments concerning the restaurant, and to address the customer entry to the second network server for writing in the customer's personal file. The network server may also be configured to compile a searchable database reflecting customer entries made in a number of different customer files.

A nerve stimulating drill bit is provided and can include a shank and a body attached to the shank. The body can include a plurality of flutes and a cutting tip. Further, a first conductor can extend through the shank and the body. The first conductor can be insulated and can provide a signal at the cutting tip. Further, the signal can be configured to provide nerve stimulation at the cutting tip of the nerve stimulating drill bit.

A device that releases an operating collar from an open position on the mast of an opened beach or patio umbrella in the presence of a strong wind, allowing the umbrella canopy to close thereby diminishing the wind force acting on the umbrella. The device includes a locking pin and an associated biasing mechanism. In a working configuration of the device, the pin is exposed for insertion through certain holes in the mast. A distal end of the mechanism faces the mast while a proximal end of the mechanism applies a bias force to a proximal end of the pin. The collar rests on the inserted pin with enough force to overcome the bias force tending to eject the pin. When the collar is urged to rise because of a strong wind acting on the umbrella, the pin ejects thus freeing the collar to move downward as the umbrella canopy closes.

Pedicle screws are inserted in spinal vertebrae in a manner to reduce the likelihood of nerve damage caused by improper screw placement. A screw opening is started in part of a skeletal region, e.g., a pedicle of a lumbar vertebra and an electric potential of a certain magnitude is applied to the inner surface of the opening while the patient is observed for nervous reactions such as leg twitching. The opening continues to be formed while the electric potential is applied until a desired hole depth is obtained in the absence of nervous reaction to the potential. The direction in which the screw opening is being formed is changed to a direction other than the last direction, after observing patient reactions to the electric potential when the screw opening was being formed in the last direction. A tool for carrying out the procedure includes a handle and a probe tip extending from the handle for forming an opening in bone tissue. Stimulator circuitry arranged inside the handle produces an electric potential of a predetermined level, and the potential is applied to the probe tip while the tool handle is manipulated to urge the probe tip into the bone tissue.
