Abstract
A digital tape measure includes a transmitter for transmitting measurements to a remote location. The tape measure includes a housing, a flexible tape having a series of optical markings mounted within the housing, an optical sensor for sensing the optical markings when the tape is extended or retracted, a logic circuit operatively connected to the sensor for providing a digital signal representative of the distance measured, and a transmitter operatively connected to the logic circuit for transmitting the digital signal to the remote location. A receiving unit is provided at the remote location for receiving, storing, and displaying the measurements.
Claims9
A measuring, transmitting, receiving, and sawing system for use by construction crews comprising:
- (a) a plurality of digital tape measures, each digital tape measure including a flexible tape having a series of optical markings moveable between a retracted position and an extended position sensing means for sensing said optical markings on said tape when the tape is extended or retracted, a logic circuit operatively connecting to the sensing means for providing digital signals representative of distances measured, and a transmitter for transmitting said digital signals to a sawing station at a remote location;
- (b) a receiving unit means disposed at said sawing station for receiving and storing said digital signals transmitted by said digital tape measures, said receiving unit means including a receiver for receiving said digital signals, data storage means operatively associated with said receiver for storing said digital signals, and display means for displaying measurements corresponding to each of said digital signals, whereby construction materials may be cut at said sawing station according to said measurements.
A method for taking and transmitting measurements at a construction site and for sawing construction materials, such as lumber, according to said measurements, comprising:
- (a) providing a plurality of tape measures each tape measure including a flexible tape having a series of optical markings;
- (b) sensing said optical markings during takings of measurements at the construction site;
- (c) generating digital signals indicative of the distances measured based on the sensing of the optical markings;
- (d) transmitting said digital signals from said tape measures to a sawing station at a remote location;
- and
- (e) sawing the construction materials according to the measurements.
A measuring, transmitting, and receiving system for use at a construction site to measure and cut construction materials, the system comprising:
- a) a plurality of tape measures, each tape measure including
- i) a flexible tape movable between a retracted position and an extended position,
- ii) sensing means for sensing distances measured when said flexible tape is extended or retracted,
- iii) a logic circuit operatively connected to said sensing means for providing signals representative of the distances measured, and
- iv) a transmitter for transmitting said signals to a remote location;
- and
- b) a receiving unit means at said remote location, said receiving unit means including
- i) a receiver for receiving said signals transmitted by said plurality of tape measures,
- ii) data storage means operatively associated with said receiver for storing said signals, and
- iii) display means for displaying measurements corresponding to said signals, whereby construction materials may be cut at said remote location according to the measurements displayed.
