ABSTRACT:
The invention is a portable human height measuring device. The device consists of an ultrasonic distance sensor, a controller and several output units. The ultrasonic distance sensor measures a person's height. The control unit converts the electronic signals from the ultrasonic sensor to proper measuring standards. The measurement output units displays, announces, or/and prints the measurement. The device is integrated onto a baseball like cap. The ultrasonic sensor is mounted on the sun visor of the cap. The control and output units are mounted on the crown of the cap. A switch is mounted on the top of the inner cap. When the head of the person wearing the cap touches the switch, it triggers the ultrasonic sensor to start measuring. The person's height is then converted to the proper measuring unit, and communicated to the person via output units.
