Abstract
Abstract The present invention offers an "automatic digit display machine for measuring height and weight" which can measure the height and weight of human body at the same time by virtue of an illuminant (LED or bulb) on the top of the machine to slopewise emit a ray downward illuminating the human head. The ray reflects to a plane mirror which, in turn, further reflects it to a sensor (CDS or photo-electric crystal) so as to stop the impetus of flexible transmission. Meantime, the metal contact sliding upward stops at the certain position of circuit board, and thru the special circuit design of the circuit board, the digit of height of human body is displayed by the drive circuit display device. The weight of human body is displayed with digit by the said display device thru the said drive circuit in line with the micromotion generated by the weight-measuring result from the high-class scale body in general.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
145 words
An apparatus for measuring and displaying the height and weight of a human being, comprising: a platform; means for measuring the weight of a human being standing on the platform; a light source for illuminating the head of a human being standing on the platform with a beam of light; a mirror for receiving light reflected from the head and further reflecting the received light; a movable sensor system responsive to light reflected from the mirror; means for (a) moving the sensor system from a first lower position in a generally upward direction and (b) stopping the motion of the sensor system responsive to light reflected thereto from the mirror; means for determining the position of the stopped sensor system and interpreting this position as a corresponding height of the human being on the platform; and means for simultaneously displaying the measured weight and height.
Claim 2
Independent Claim
145 words
An apparatus for measuring and displaying the height and weight of a human being, comprising: a platform; means for measuring the weight of a human being standing on the platform; a light source for illuminating the head of a human being standing on the platform with a beam of light; a mirror for receiving light reflected from the head and further reflecting the received light; a movable sensor system responsive to light reflected from the mirror; means for (a) moving the sensor system from a first lower position in a generally upward direction and (b) stopping the motion of the sensor system responsive to light reflected thereto from the mirror; means for determining the position of the stopped sensor system and interpreting this position as a corresponding height of the human being on the platform; and means for simultaneously displaying the measured weight and height.
Claim 3
Dependent Claim
32 words
An apparatus according to claim 1 further including means for returning the movable sensor system to the first position after a predetermined period of time following the display of height and weight.
Claim 4
Dependent Claim
21 words
An apparatus according to claim 1 wherein the light source is infrared and wherein the sensor system includes an infrared sensor.
Claim 5
Dependent Claim
15 words
An apparatus according to claim 1 wherein the light sensor system includes a CdS cell.
Claim 6
Dependent Claim
15 words
An apparatus according to claim 1 wherein the light sensor sytem includes a photo-electric crystal.
Claim 7
Dependent Claim
15 words
An apparatus according to claim 1 wherein the light source is a light-emitting diode (LED).
Claim 8
Dependent Claim
80 words
An apparatus according to claim 1 wherein the light sensor system comprises: a generally vertical track; a block slidable in the track and having contacts thereon; a circuit board having contacts thereon; a motor and transmission for moving the block within the track, the contacts of the block making electrical contact with different contacts of the circuit board as the block moves within the track, the particular contacts of the circuit board being contacted indicating the position of the block.
Claim 9
Dependent Claim
47 words
An apparatus according to claim 7 wherein the transmission comprises: a driving belt roller attached to a shaft of the motor; a second belt roller on the track, and a transmission rope looped about the driving belt roller, the second belt roller and coupled to the block.
Claim 10
Dependent Claim
55 words
An apparatus according to claim 7 wherein the circuit board includes electronic means for determining a height signal for driving a digital display as a function of the particular contacts of the circuit board that are electrically contacted by the contacts of the slidable block; and wherein the means for displaying comprises a digital display.
