Abstract: A dental x-ray sensor holder adapted for engaging a portion of an x-ray tube and holding a digital sensor inside a patient's mouth. The holder includes a holder base arm with a first and second tube arm. The first and second tube arms are adapted for engaging a portion of a side of the x-ray tube and hold the tube in a fixed position next to a patient's cheek. The holder also includes a buccal arm adapted for receipt inside the patient's mouth and next to a buccal side of a tooth under review. The buccal arm includes an elongated arm opening for receiving a portion of a sliding interoral position arm. The position arm is attached to a digital x-ray sensor. The position arm is used to adjust the sensor in the middle of the patient's mouth.

Abstract: A system for measuring the lateral acceleration of a vehicle. The system includes an accelerometer that measures the lateral gravitational forces, an annunciator that announces the changes in the lateral gravitation forces, a data logging for storing the measured changes and the relative times and a controller. This system is particularly useful for training for performance driving such as racecar drivers and law enforcement drivers.
