  • Including a microphone and recording function can enable the system to have voice recognition where the user can command the unit with their voice. It also means the user could record audio to be used as indicators in the system.
  • FIG. 20 System Initialisation
  • FIG. 20 provides an overview of system initialization for running a new process as would be recognised by the person skilled in the art.
  • FIG. 21 Emergency Stop Process
  • the process illustrated in FIG. 21 may be performed by an interrupt as it can occur at anytime that the unit is active and should be able to be activated at any time the unit is active.
  • the emergency stop may be triggered by sensor devices that detect movement of the projecting apparatus or an intrusion into the apparatus that may affect the operation or cause injury to a player. Once activated, all moving parts that launch the article will be stopped. An exit gate will be closed to stop the article leaving the apparatus. A release/stopper gate will be closed/checked to make sure no more articles can enter the cycle/apparatus. An indicator may alert the user or players that this emergency stop process has taken place.
  • the “Return from emergency stop” is a process that may take place to enable any articles that are idle in the launch process to leave the apparatus or allow the user and/or players to remove obstructions themselves safely.
  • Load Trajectory/Acceleration Motor Parameters These may be pre determined and set by the user and/or player or may be set to load random parameters from a Random Number Generator (RNG) and translated. These settings may be loaded from previously automatically generated parameters from the last used settings. These parameters may be determined as per signature of the projected article and its assigned settings in accordance with the unique identity that is conveyed by the article's transponder.
  • Load Loft motor Parameters These may be predetermined and set by the user and/or player or may be set to load random parameters from a Random Number Generator (RNG) and translated. These settings can be loaded from previously automatically generated parameters from the last used settings. These parameters may also be determined as per the signature of the article and its assigned settings.
  • Load direction Motor parameters These parameters may be pre determined and set by the user or may be set to load random parameters from a Random Number Generator (RNG) and translated. These settings can be loaded from previously automatically generated parameters from the last used settings. Once again, these parameters can be determined as per signature of the article and its assigned settings.
  • RNG Random Number Generator
  • Run direction motor This process step moves parts that affect direction on the horizontal plane.
  • Check stopper/release detector to see if article is present. If present/full check exit detector. If empty wait count time and check if elapsed and if so, set fault indicators which can be tones to alert the user. Check exit detector to make sure exit path is clear.
  • Run acceleration/trajectory motors Open the exit gate to allow the article to leave the system. Open stopper/release gate so the article passes to the acceleration devices.
  • Check stopper/release detector to see if the article has left the zone. Close stopper/release gate to stop next article. Exit detector will sense if article has passed. If so Shut down Acceleration/Trajectory motors. Check Exit detector is empty.
  • exit detector is empty, Close the exit gate. Close stopper/release gate. Check to see if in auto mode. If in auto mode, Check to see if time delay is random. Perform time delay as set by the user or may be set to load random parameters from a Random Number Generator (RNG) and translated.

  • FIG. 24 shows a simple overview of the software flow and its interfacing with hardware.
  • the process illustrated in FIG. 25 shows that the remote control can mirror the indicators and selectors that the apparatus uses.
  • the indicators are for the user to be warned or alerted of certain states and conditions of the unit and its functions. If a projectile 10 is about to exit, then a warning indicator may alert the user or anyone in the vicinity.
  • the indicator may comprise visual, audible signals or both.
  • the indicator may be a voice recording of the user/owner via a microphone on the unit using the software. This can be used for dog training where the owner can record “Get ready . . . Sit . . . Fetch boy”. This will be included in the software and positioned/timed in the flow of the program.
  • a visual indicator can alert the user that a projectile is coming.
  • projectiles may have on board sensors to enable the sensing that has been discussed in the description herebefore.
  • an audible sound can alert the user until power is so low that the machine will not operate and is shut down automatically. This can be a series of whistles/beeps/tones.
  • the remote is an ‘extension’ of the user interface and can be a ‘parallel’ function such as ‘start/activate’.
  • the remote can also be used to launch projectiles on demand. It can be used to do anything that the user interface can do.
  • the remote device may have selectors and indicators such as buttons, LED's, Audible, LCD screen.
  • the remote may act as a transceiver that receives information from the launching unit. Eg. updating user settings, confirmations, modes, synchronisation, other indicators such as power etc.
  • the unit may comprise both an external and internal power supply.
  • the external supply can be used to power the unit, charge the internal power source or do both at the same time.
  • the internal chargeable supply makes the unit portable and able to use anywhere. It is also a safety precaution that prevents dogs, humans or the environment from interfering with the power supply and in particular a dangerous source. ie dogs chewing cord, rain and moisture, unattended unit.
  • the power supplies will have their own ‘normal’ protection devices such as fuses, moisture sensors and thermal sensors perhaps, for safety reasons. In so being, it is possible that the system may not be reliant on whether a battery is part of the unit, or perhaps batteries are inserted with the unit providing the charge circuit so batteries can be replaced but never have to be taken out.
  • All moving parts and devices can be run using hardware, software or a combination of both. Where functions do not need software simple hardware can be the controller. Where functions and their parameters are dynamic, changeable and/or ranged then software via a processor may be used.
  • the software enables the unit to have full control of the wheel mechanisms and makes the projectile delivery extremely dynamic. It also enables the user to make settings, save settings and to randomize its function. Randomisation is good for lack of prediction for the user. It can randomize all or certain parts of the projectile behaviour, as the user may require a consistent part of the function eg. Not short. Always top-spin and randomise the rest of the units movements as in loft, side spin persuasion, direction.
  • the shell, base 19 and chassis 18 may be independent structures that join together. Ultimately and ideally the base may always remain stationary, with the chassis and shell (receptacle and top) attached but able to move independently and with reference to the base, as this comprises the projectile direction device.
  • the base may have legs fitted that are normally at level but are independently adjustable to allow for undulating ground or tilt of the unit (without the stand).
  • the base 19 and chassis 18 and shell may be fixed, and is not limited to being independent to include the particular function of the x plane direction device.
  • the launcher unit may be placed on a stand that alters the height of the unit and can change the angle of the horizontal plane that the unit sits and projects on.
  • the stand may comprise a base, top and legs.
  • the base can be weighted for stability of the unit.
  • the top can be a receptacle for the launcher unit so it can fit or be mounted and attached to it.
  • the legs can be adjustable, telescopic perhaps allowing the units height and thus trajectory to be altered. With four telescopic legs and universal joints fixing them to the base and top with one of the eight joints/mountings fixed and preferably not allowed to move, the unit can go on any angle of the horizontal plane that the length of the legs allows. When the legs are completely retracted or fully extended, where the legs are even length, the unit will be perfectly level. As soon as the legs are locked in length, the unit will become rigid with the assistance of the single fixed end of a leg opposed to the seven uni joints. When two adjacent legs are locked, and the opposing two are open, the stand only tilts on one axis.
  • the stand can include 3 dimensional levelling indicators, such as a bubble/fluid indicator for accurate setting.
  • legs may be included in and under the base that are normally at level but are adjustable to allow for undulating ground.
  • a tripod with a universal head can be used, but may be unstable as the surface area of the ‘top’ is large and will have moving parts and forces placed against it. (unless locking mechanism is strong enough)
  • the receptacle means may extend to comprise a device that may be included to allow continuous play/function of the unit. It can also be used as a training and skills development tool.
  • a ‘recycling’ device as such can be included where a receptacle receives a returned and intervened projectile that was initially launched from the unit.
  • the ‘recycler’ catches, directs and dampens the projectile that drops to a channel or constantly descending graded vessel that directs the projectile to a specific target point and exit.
  • the target point and exit are placed above the launching unit allowing the projectile to be reintroduced to the launcher receptacle and thus launching system, completing a cycle.
  • this recycling process may also be achieved without this unit, as in a dog returning the projectile to the generously proportioned receptacle and completing the cycle. This can also be a training system.
  • This recycler with its catcher or target zone can be height adjustable.
  • the stand can be weighted for stability and anchoring to compensate the force of returned projectile.
  • the weight can be fixed or detachable/attachable.
  • the stand can be anchored by means of attaching rope and anchoring it in front of the stand in the ground or anchored directly in to ground with pegs. It can be anchored to a tennis net where the unit and stand can be situated on the other side of the tennis court net as the user and the recycling net and frame can be attached to the tennis court net by way of clips and guide ropes.
  • a sensor may be placed on auxiliary receptacles, in the form of nets and/or hoppers, and communicate with the operating software. This may enable a quicker re-delivery which can simulate ‘real time’ play. It may also determine if an article has been returned successfully in the receptacle and within a certain or given time frame.
  • various sensors may be provided on various receptacles, or various parts of the same receptacle. These sensors may communicate with the unit via a cable and I/O port, or via other communications technology that would be recognised by the person skilled in the art.
  • the sensor detection at the receptacle may also be logged for statistics such as returned articles vs. projected articles.
  • the receptacle means may comprise a conical shaped net coupled to the top of the launching means so for instance, a circle of cricketers may stand around the launcher, catch the balls, and throw them back into the cone which feeds the receptacle for providing further flow of balls to the launcher.
  • the drive means may comprise wheels made of different materials, with varying thicknesses, density, grip etc depending on the opposing gripping surface of the projectile so as to match them for optimum behavior control.
  • means-plus-function clauses are intended to cover structures as performing the defined function and not only structural equivalents, but also equivalent structures.
  • a nail and a screw may not be structural equivalents in that a nail employs a cylindrical surface to secure wooden parts together, whereas a screw employs a helical surface to secure wooden parts together, in the environment of fastening wooden parts, a nail and a screw are equivalent structures.
