Abstract

Disclosed is a pressure-responsive vehicle alarm pad for a vehicle seat to remind a presence of an object inside a vehicle to an occupant of the vehicle seat. The pressure-responsive vehicle alarm pad comprises a pressure sensor pad, a control circuitry, and alarm speakers. The pressure sensor pad disposed on the vehicle seat to detect a pressure of the occupant. The control circuitry electrically coupled to the pressure sensor pad to receive the detected pressure from the pressure sensor pad. The control circuitry generate a first electrical signal when the detected pressure is greater than a threshold pressure, and generates a second electrical signal when the detected pressure is less than the threshold pressure. The alarm speakers electrically coupled to the control circuitry to generate a first audible sound in response to the first electrical signal, and generate a second audible sound in response to the second electrical signal.

Claims

1. A pressure-responsive vehicle alarm pad to remind a presence of an object inside a vehicle to an occupant of a vehicle seat, the pressure-responsive vehicle alarm pad comprising:

a pressure sensor pad disposed on the vehicle seat for detecting a pressure of the occupant;

a control circuitry electrically coupled to the pressure sensor pad, the control circuitry configured to

generate a first electrical signal when the detected pressure is greater than a threshold pressure, and

generate a second electrical signal when the detected pressure is less than the threshold pressure; and

an alarm speaker electrically coupled to the control circuitry, the alarm speaker configured to

generate a first audible sound in response to the first electrical signal, and

generate a second audible sound in response to the second electrical signal to remind the presence of the object inside the vehicle to the occupant.

2. The pressure-responsive vehicle alarm pad of claim 1, further comprising at least one hook strap and a roll strap, the at least one hook strap and the roll strap securing the pressure-responsive vehicle alarm around the vehicle seat.

3. The pressure-responsive vehicle alarm pad of claim 2, wherein the at least one hook strap and the roll strap are attached on opposite sides of the pressure sensor pad.

4. The pressure-responsive vehicle alarm pad of claim 1, further comprising a reset switch electrically coupled to the control circuitry, the reset switch configured to reset the first electrical signal and the second electrical signal.

5. The pressure-responsive vehicle alarm pad of claim 1, further comprising a sound record switch electrically coupled to the control circuitry for recording the first audible sound and the second audible sound.

6. The pressure-responsive vehicle alarm pad of claim 1, further comprising a battery for supplying power to at least one of the control circuitry and the alarm speaker.

7. The pressure-responsive vehicle alarm pad of claim 1, wherein the pressure sensor pad is a capacitive pressure sensor.

8. The pressure-responsive vehicle alarm pad of claim 1, wherein the pressure sensor pad is an elastomer pressure sensor.

9. The pressure-responsive vehicle alarm pad of claim 1, further comprising a water resistant sheet disposed on the pressure sensor pad.
