Vehicle safety belt bypass warning system
First Claim
1. A vehicle safety belt bypass warning system for a vehicle having an ignition system and at least two seats within the vehicle, the vehicle safety belt bypass warning system comprising:
- a) a video camera having a field of view and wherein each of the at least two seats is within the field of view;
b) at least one processor within the vehicle;
c) face detection software, executable by the at least one processor, that will enable the processor to recognize, for each of the at least two seats, human faces;
d) wherein each of the seats has associated therewithi) a safety belt, extendable from a retracted position to a second position and retractable from the second position to the retracted position; and
ii) a safety belt engagement sensor circuit that detects when a safety belt latch plate of the safety belt, is received in and latched by a corresponding safety belt latch plate receiver, and a seat occupation sensor coupled to the seat that senses when at least a minimum weight is on the seat;
e) wherein an individual seat of the at least two seats is an occupied seat when the seat occupation sensor senses at least the minimum weight, the safety belt engagement sensor circuit detects that the safety belt is latched, and the processor detects that a human face is present and associated with the individual seat;
f) an infrared (IR) emitter output, positioned on the safety belt, that is enabled after the ignition system has been engaged, if the seat is occupied, and, once enabled, will transmit individually coded light pulses, unique to the occupied seat, for a period of time;
g) at least one IR receiver within the vehicle, that is enabled when at least one IR emitter output is enabled and is positioned to receive individually coded light pulses from occupied seat IR emitters during the period of time and, in response to receipt, will output one or more coded electrical signals indicative of which of each occupied seat that the individually coded light pulses were received from; and
h) wherein the at least one processor is coupled to the at least one IR receiver, and will wait for receipt of one or more coded electrical signals output from the IR receiver during the time period, the one or more coded electrical signals specifically indicating each seat that has a non-bypassed safety belt, and if the processor does not receive an indication for a particular occupied seat, the processor will trigger a safety belt bypass warning indicator to indicate that the particular occupied seat has a bypassed safety belt.

Abstract
A vehicle safety belt bypass warning system involves, a video camera, at least one processor, face detection software, a safety belt, and a safety belt engagement sensor circuit. The processor detects that a human face is present and associated with an individual seat. An infrared (IR) emitter output is positioned on the safety belt and transmits individually coded light pulses unique to the occupied seat. At least one IR receiver receives individually coded light pulses from occupied seat IR emitters and, in response, will output coded electrical signals indicative of which occupied seat(s) the individually coded light pulses were received from. The at least one processor will wait for receipt of the coded electrical signals from the IR receiver. If the processor does not receive an indication for a particular occupied seat, the processor will trigger a safety belt bypass warning indicator.
