Definitions

  • the present invention relates to visual display systems.
  • the wheels of bicycles are often decorated with material which gives a pleasing effect to a remote viewer.
  • the wheel rotates and rotates at different speeds little more than a blur of colour is usually observable.
  • UK Patent Specification No 2277189 discloses a wand supporting an array of light emitting diodes which are programmed to be illuminated in a particular sequence to display a desired apparently stationary image. In order for the image to be displayed at a particular orientation, the angle of the wand and its speed are detected with respect to a hanging weight or gyro that remains unchanged in position when the wand moves.
  • UK Patent Specification No 2272791 discloses a light emitting diode matrix which can be fitted to a bicycle wheel to display an apparently stationary message.
  • Both these devices rely on a separate component which does not rotate with the wheel to determine the angular position and speed of the wheel.
  • a display system for a rotary wheel mounted for rotation about an axis inclined to the direction of the gravitational field comprising an elongate array of light emitting devices to be mounted on the wheel extending in a radial direction, a controller to be mounted on the wheel and connected to the light emitting devices for controlling the energisation of the light emitting devices in a sequence in accordance with a program stored in a memory of the controller, an accelerometer to be mounted on the wheel spaced from the axis of the wheel to provide an output indicative of the speed and angular position of the wheel, and control means responsive, each time said output indicates that a predetermined angular position has been reached to initiate an energising cycle for the array of light emitting devices by the controller at instants in the cycle determined in accordance with the program stored in the memory, the control means varying the rate of energisation in accordance with the speed of the wheel whereby to provide an apparently stationary image on the wheel corresponding to the program stored.
  • Figure 1 shows a bicycle 2 having a front wheel 4 carrying an illuminated image of a registered trade mark REEBOK which, to the stationary observer, appears stationary on the bicycle notwithstanding that the wheel 4 is rotating.
  • the wheel 4 is supported by a fork 6.
  • Attached to one spoke 8 of the wheel 4 is an elongate array 10 comprising sixteen light emitting diodes (LEDs) extending radially of the wheel 4.
  • a controller 16 which includes a battery (not shown), and is connected to the array 10 by a cable 18.
  • the imbalance caused by the attachments to the wheel can be corrected by the use of counterweights (not shown) attached to the diametrically opposite side of the wheel.
  • the controller includes a memory (not shown) that stores a program for controlling the sequence in which the different LEDs of the array are to be energised.
  • the effect is achieved because with light flashes of very short duration, the reaction of the human eye to the flash persists long after the flash has finished.
  • a series of very short flashes occur over a short time span, less than 0.015 seconds, all the flashes appear to the eye to have occurred at the same time and when the flashes are spaced from one another on the retina because the array has moved relative to the retina, the eye perceives a composite light pattern which will persist for a short while immediately following the time span.
  • a program can be created and stored in the memory which will produce almost any desired image for the observer.
  • the image may take the form of alphanumeric information or may take the form of an advertising poster.
  • the rotation of the wheel has to be sensed.
  • An accelerometer 14 is mounted on the wheel at a point radially distant from the axis of the wheel. As the wheel rotates, the accelerometer will have a component of motion in the direction of the gravitational field and this will cause the accelerometer to generate a sinusoidal electric output indicative of both speed any angular position of the wheel as the wheel rotates. This output can then be used by the controller to illuminate the LEDs at any desired attitude as the wheel rotates.
  • Control means (not shown) within the controller 16 responds to the output to initiate the readout from the memory at the same angular position of the spoke 8 during each full cycle of rotation of the spoke.
  • the control means also determines the speed of the wheel and inhibits a readout from the memory until the speed of the wheel reaches 35 rpm. After this point has been reached, the control means controls the readout rate from the memory to the array directly in proportion to the instantaneous repetition rate determined by the control means.
  • FIG. 3 shows how the memory of the controller 16 can be programmed.
  • a desired image is created with the aid of an IBM PC compatible computer 20 and configured as a 200 x 16 pixel array.
  • the array is downloaded into a programmer 22 which converts the driving data stream into a processor compatible processing stream.
  • the processor in turns loads the program for the array into the memory of the controller.
  • power can be fed from a source mounted on the bicycle frame to the wheel through a slip ring arrangement.
  • the controller 16 can be in two parts, a first part fixed to the spoke and a second part which can be plugged into the first part which contains the power supply (the batteries) and the memory.
  • the plug-in part can be removed for security purposes and/or to reprogram the memory.
  • any number of arrays can be mounted on the wheel in different attitudes and shapes to form a complex display pattern as required.
