An automatic revolution counting and data transmission device for measuring full or partial revolutions of a shaft, processing, storing, and transmitting said revolutions and related data. An embodiment of the invention as a hubodometer for measuring rotations of a wheel uses of a housing (1), printed circuit board (3) with all electronic circuitry for counting data, data storage, and two way data communication, and an anti-rotation device. A low power radio frequency transmitter and receiver are used to receive commands and to transfer stored data to a receiving unit which may be a portable battery-powered unit or a fixed-mount unit. Such data transfer by RF link eliminates the inherent problems associated with visual readout or optical data transfer from units located where dirt grime buildup is common. |

DETAILED DESCRIPTION The invention consists of a housing and a small central shaft attached to the housing with the housing being permanently attached to the rotating object for which revolutions are to be counted.
Inside the housing is an anti-rotation device with an attached electronic printed circuit board containing all electronic components and circuitry (p.
c.
) board remains stationary relative to the rotation of the housing around the p.
c.
board and in relation to the small shaft which passes through the center of the printed circuit board.
Counting of rotations by the circuitry on the printed circuit board is accomplished by one of several means depending upon the accuracy required in the count data.
For devices requiring count resolutions only in complete revolutions (such as the embodiment as a hubodometer) a magnet is attached to the rotating housing.
This magnet then activates a reed switch which the electronic circuitry senses to count revolutions.
For devices requiring a higher degree of accuracy, a slotted disk or a gear is attached to the rotating shaft which passes through the center of the p.
c.
board.
An optical scanner is used to detect the slot's rotational movement or a gear tooth sensor is used to sense rotation of a gear.
The number of slots in the rotating disk or the number of gear teeth is varied by the application.
A microprocessor chip on the printed circuit board is used to control the logic for counting revolutions, to store the revolution count date in RAM memory, and the control and monitor the radio frequency receiver circuitry and data transmission circuitry, all contained on the p.
c.
board.
Operation of the invention is extremely simple.
In its most basic embodiment the device will simply transmit an equipment identification number and a total number of revolutions any time it receives a coded transmission from a separate transmitter/receiver device which would normally be connected to a computer or computer terminal.
Since a microprocessor is used within the invention, this processor can be used to maintain and then transmit other information that may be desirable for a particular application
