A technique for reinforcing seatbelt usage in automobiles is described. One implementation of which includes a weight sensor in the car seat that detects occupancy by a person and generates an occupancy signal that is transmitted to a seatbelt monitor unit that receives both the occupancy signal and a buckled seatbelt signal (based on a magnetic switch in the female portion of the buckle), and based thereupon, generates an unbuckled seatbelt alarm signal if the buckled seatbelt signal indicates that the buckle is not buckled when the transmitted occupancy signal indicates that the respective seat is occupied. A program executing on the automobile's stock computer then receives the unbuckled seatbelt alarm signal from the seatbelt monitor unit and handicaps the operation of the automobile in a predetermined way (e.g., speed limitation, engine kill, etc.).

Apparatus for reinforcing seatbelt usage in automobiles

A method and apparatus are provided for translating small voltage continuous signals into large full supply signals to generate a clock signal. At least one oscillator input signal is applied to a first amplifier stage for generating an amplified voltage output signal. A first inverter is coupled to the first amplifier stage. A second inverter is coupled to the first inverter. An AC coupling capacitor couples the amplified voltage output signal to the first inverter input, and a feedback resistor is connected between the output and input of the first inverter.

An integrated biquadratic, continuous-time filter section includes a plurality of operational transconductance amplifiers (OTAs). Simutaneously changing a transconductance (GM) of each of the OTAs is provided by adjusting a differential voltage applied to a plurality of differential transistor pairs of each OTA. Each of the OTAs include a plurality of current sources and a common mode feedback circuit for controlling a common mode output voltage level. Changing the transconductance of the OTA is independent of the common mode voltage level control.
