Patent ID: 7360421

Claim:
A system for determining speed of a vehicle, comprising: a sensing unit comprising: (a) a sensor in a housing; (b) a transmitter connected to the sensor; (c) a flexible and positionable arm connected to the housing at one end for adjustably supporting the sensor in one of several different positions; (d) an adjustable securing device connected to another end of the flexible and positionable arm; (e) a LED light which indicates adequate proximity to a magnet; a display unit comprising: (a) a receiver for receiving data from the transmitter; (b) a microprocessor connected to the receiver for processing data received by the receiver; and (c) a display for displaying data processed by the microprocessor; and a magnet adapted to be connected to a spoked or non-spoked wheel of the vehicle, wherein when said magnet is connected to the vehicle wheel, and the sensing unit is connected to the vehicle via the securing device, the sensor can be positioned adjacent the magnet by moving the flexible arm into place so that the sensor receives pulses from the magnet as the magnet passes the sensor during rotation of the wheel.
