  • the other coil detects the unique electronic signature which, if acceptable, permits the dispensing system to dispense material.
  • the system thus utilizes a near field frequency response to determine whether the refill container is compatible with the dispensing system.
  • a mechanical latching arrangement is provided to retain the container to the housing to ensure correct positioning of the coils.

  • the activation unit 48 shown is adapted to be used as a touchless dispenser in which the presence of a user's hand below the presser member 15 underneath the discharge outlet 34 is sensed by a hand sensing system including an electromagnetic radiation emitter 53 located at the bottom front of the activator unit 48 to direct radiation downwardly and forwardly towards the position the user's hand is to be placed and an electromagnetic radiation sensor 54 also located near the bottom front of the activation unit 48 adapted to sense radiation reflected off the user's hand.

  • the collar 26 may be formed as unitary element all from the same radiation transmitting properties or may be formed from a number of different materials. For example, to increase internal reflection, exterior surfaces of the collar 26 especially about the rim 65 could be coated with a reflective material other than on the inlet end face 62 and the outlet end face 63.

  • frangible member 220 may vary widely.
  • the objective is to provide an arrangement such that with insertion or removal of a removable component, comprising in the case of the preferred embodiment the reservoir assembly 12, a portion of a waveguide carried by the removable reservoir assembly 12 becomes changed such that a control system can recognize a reservoir assembly 12 which has been coupled or uncoupled more than once and make an appropriate selection as to how to deal with this in control of the dispenser as one example, when the control system recognizes that a reservoir assembly has been coupled or uncoupled more than once then the control system may prevent dispensing of the material.
  • control system when the control system recognizes that a reservoir assembly has been coupled or uncoupled more than once, then the control system may merely permit thereafter a given number of activations of the piston pump after which the control system will prevent dispensing.
  • first optical paths between key emitter 55 and key sensor 56 and a second optical path between key emitter and 255 and key sensor 56 there are two distinct optical paths, a first optical paths between key emitter 55 and key sensor 56 and a second optical path between key emitter and 255 and key sensor 56.
  • the possibilities for the control system sensing include the following:
  • a first rule of operation for the control system preferably is that operation is only permitted when the control system senses passage of electromagnetic radiation through the first optical path, that is there is either (A) Double Positive or (C) First Positive/Second Negative.
  • a counter mechanism for the control system is to count activation of the piston 32 when there is electromagnetic radiation through the first optical path thus, under either condition (A) double positive or condition (C) First Positive/Second Negative.
  • a second rule of operation is preferably is that after a maximum number of activations have been counted since the last resetting of the counter mechanism that operation of the pump is prevented. The maximum number of operations can be selected having regard to the volume of the fluid in any reservoir assembly which has been applied and the volume of dosage that is the amount of liquid which is to be dispensed by the piston 32 in a typical activation.
  • a maximum number of activation could be selected to be, for example, 1000 activations, however, preferably there will be some buffer for inaccuracy of strokes, for example, an additional 5 percent to 25 percent thus representing, for example, as a maximum being selected between preferably 1050 and 1250 activations.
  • the count preferably may be reset to zero at a time when in sequence the control system after sensing no radiation through the first optical path, that is either condition (B) double negative or condition (D) First Negative/Second Positive the senses (A) Double Positive.
  • This is equivalent to a situation in which the reservoir assembly is removed such that (B) the Double Negative is sensed and then a new reservoir assembly with its fragile member 220 in tact is applied, in which case the reservoir assembly would be expected to have its reservoir is filled of fluid and it is reasonable to reset the counter to zero and permit in the normal course operation of the dispenser for dispensing of all of the fluid from the reservoir, stopping operation however preferably if more than a maximum activations have been carried out as reasonably necessary to empty the reservoir. Having the maximum number of activations used to stop operation when there has been a continuous double positive is not necessary but preferred.
  • condition B a Double Negative would be sensed. If the same reservoir assembly is removed and then recoupled, such reservoir assembly will not have the frangible member 220 attached. On recoupling, there will be a sensing of condition C being First Positive and Second Negative. On such sensing, the control system will not restart the counter to zero but will continue with the same count. This permits a reservoir assembly which has been removed and recoupled to continue to be dispensed, however, only to the maximum number of activations. The same reservoir assembly may thus be removed and recoupled a number of times with a counter mechanism continuing to count and operation being permitted until such time as the maximum number of activations has arisen.
