Steering wheel lock having an ultrasonic-wave alarm system
First Claim
1. A steering wheel lock having an ultrasonic-wave alarm system, comprising:
- a mechanical lock to be mounted on a steering wheel so that the rotation of said steering wheel is limited; and
an anti-theft alarm circuit located within a top shell of said lock, said anti-theft alarm circuit being activated upon the engagement of said lock and said steering wheel, said anti-theft alarm circuit further including at least a set of detecting unit and a central processing unit for detecting moving objects inside an automobile, said detecting unit consisting of an ultrasonic wave emitter for sending ultrasonic waves outwardly and an ultrasonic wave receiver for receiving/treating ultrasonic waves reflected back, said reflected waves being sent to said central processing unit for recognition, whereby signals being recognized as anomalous will trigger a predetermined alarming process.

Abstract
A steering wheel lock having an ultrasonic-wave alarm system includes a lock main body to be mounted on a steering wheel so that the rotation of the steering wheel is constrained and an anti-theft alarm circuit located within an outer shell of the lock main body, which is activated upon the engagement of the lock main body and the steering wheel. The anti-theft alarm circuit further includes at least a set of detecting unit and a central processing unit (CPU) for detecting a moving body in the automobile. The detecting unit consists of an ultrasonic wave emitter for sending ultrasonic waves toward the inner space of the automobile and an ultrasonic wave receiver for receiving and treating the reflected waves. The treated signals are sent to the CPU for recognition. If the signals are anomalous, the anti-theft alarm circuit will start a predetermined alarming process to scare away suspicious people and to notify the automobile owner.
