The United Kingdom ratified the UN Convention on the Rights of Persons with Disabilities (CRPD) in June 2009, signifying commitment to the human rights of people with disabilities at a broad level.
An occupant position detection system comprising: distance sensor means located on a seat back of a seat of a vehicle; angle sensor means for sensing an inclined angle of the seat back; and sliding displacement sensor means for sensing a displacement value of the seat in fore and aft directions; wherein an occupant position is detected by the distance sensor means, the angle sensor means and the sliding displacement sensor means.
Occupancy sensors have a limited sensing range. Sensors can detect slight hand motion up to 3 m and full body motion up to 10 m. Ultrasonic sensors offer better detection than PIR sensors. In rooms where it is critical that lights do not go off incorrectly, dual technology (PIR and ultrasonic) sensors can be used. Occupancy sensors can reduce lighting energy use by 30 to 60%, depending on the frequency of room usage.
