   BACKGROUND OF THE INVENTION 
   The subject invention relates to cigarette monitoring means operable to monitor aspects of cigarette mainstream smoke whilst a cigarette is the subject of human, as opposed to machine, smoking. 
   Known in the tobacco industry are cigarette monitors comprising a cigarette holder by which may be mounted a cigarette at the mouth end of the cigarette. In unit with the holder is a mouthpiece by means of which a cigarette mounted in the holder can be smoked by a human smoker, the mouthpiece being in fluid-flow communication with the mouth end of such cigarette. Betwixt the mouth end of such cigarette and the mouthpiece are disposed elements of fluid-flow pressure drop detection means and smoke density detection means. Such known cigarette monitors further comprise a data processing unit, the cigarette holder being connected to this unit by tubes of the fluid-flow detection means and electrical leads of the smoke density detection means. Such devices, however, do not provide actual smoking delivery values, merely a means of recording a real-time puff delivery profile. 
   It is an object of the subject invention to provide an improved cigarette monitoring means. 
   SUMMARY OF THE INVENTION 
   According to a first aspect thereof the subject invention provides cigarette monitoring means comprising: 
   cigarette mounting means by which a cigarette can be mounted at the mouth end thereof, said mounting means comprising a mouthpiece, which mouthpiece is, when said mounting means mounts a cigarette, in fluid-flow communication with the mouth end of the cigarette; 
   in unit with said mounting means fluid-flow pressure drop detection means and smoke density detection means; 
   at the location of said mounting means data transmission means operable to transmit data derived from said pressure drop detection means and said smoke density detection means; 
   data receiving and processing means operable to receive and process data transmitted by said transmission means, the processing effected by said processing means comprising a calculation of a delivery value of particulate phase smoke components from a cigarette when mounted by said mounting means and being smoked via said mouthpiece; and

   Preferably the mouthpiece is in gas-flow communication with the mouth end of the cigarette. 
   Advantageously, and in addition to advising the consumer of their real-time smoking behaviour, in either aspect of the invention, the associated display means or second display means associated with the cigarette monitoring device may display information that is of interest to the smoker, for example, alternative products of the smoking article manufacturer that may be of interest to the consumer, and may offer in addition or alternatively, means to provide a direct sales service to the smoker of the same or alternative products, or indeed other products or services not being smoking articles or related thereto. 
   As well be appreciated by a man skilled in the art, the monitoring device will be operable with any smoking article, such as cigar, or any other smoking article device that produces particulate material that could be assessed by the smoke density detection means and termed ‘smoke’. 

   
     BRIEF DESCRIPTION OF THE DRAWINGS 
     In order that the subject invention may be clearly understood and readily carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which: 
       FIG. 1  shows a block diagram depiction of a first cigarette monitoring apparatus; 
       FIG. 2  shows a block diagram depiction of a second cigarette monitoring apparatus, being a modification of the apparatus of  FIG. 1 ; and 
       FIG. 3  shows a block diagram depiction of a third cigarette monitoring apparatus, being another modification of the apparatus of  FIG. 1 . 
   

   DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   The cigarette monitoring apparatus of  FIG. 1  comprises a cigarette mounting assembly  1  and a monitoring assembly  2 , which assembly  2  will, in use of the apparatus of  FIG. 1 , be located remote the cigarette mounting assembly  1 , at a distance of tens or hundreds of yards, for example. The distance may even be one that is measured in miles. 
   The cigarette mounting assembly  1  comprises a housing  3 , at one end of which is secured a hollow sleeve  4  and at the opposite end of which is secured a mouthpiece holder  5 . A cigarette ( 6 ) can be mounted in the sleeve  4  and a disposable mouthpiece ( 7 ) can be mounted in the holder  5 . With such a cigarette and such a mouthpiece mounted of the housing  3 , the mouthpiece is in fluid-flow communication with the cigarette via the hollow interior of the housing  3 , such that the cigarette may be smoked via the mouthpiece. 
   Mounted within the housing  3  is an orifice plate  8  and, one to each side of the orifice plate  8 , are mounted pressure detectors  9  and  10 . Also mounted within the housing  3  are a light emitter  11  and, opposed to the transmitter  11 , a light receiver  12 . 
   In unit with the cigarette mounting assembly  1 , i.e. fixedly or detachably secured thereto, is a data transmission module  13 . The module  13  is operable to receive pressure signals from the pressure detectors  9  and  10  and a light signal from the light receiver  12 , and to transmit to the monitoring assembly  2  data derived from these pressure and light related signals. This transmission is by conductorless, i.e. “wireless”, electromagnetic wave means; it can be a radio frequency transmission, for example. 
   The monitoring assembly  2  comprises a data receiving and processing module  14  and, in unit therewith, a display module  15 . The module  14  is operable to receive aforesaid data transmitted by the module  13  and to process this data. The processing of the data produces, or includes, a real-time value of the delivery of the particulate phase components of the mainstream smoke (demotically known as “tar”) of a cigarette ( 6 ) which is mounted in the sleeve  4  of the housing  3  and is being smoked via a mouthpiece ( 7 ) mounted in the holder  5  of the housing  3 . 
   Processed data, such, for example, as the real-time values of “tar”, can be displayed by the display module  15 , on a display screen thereof, for example. 
   As will be readily appreciated by those possessing routine skill and knowledge in the art, from the pressure difference across the orifice plate  8  within the housing  3 , which pressure difference can be derived from the pressure signals from the detectors  9  and  10 , there may be calculated instantaneous values of flow rate of the mainstream smoke from a cigarette ( 6 ) mounted in the sleeve  4 . Similarly, the obnubilation effected by the mainstream smoke on the light emitted by the light-emitter  11 , which obnubilation is registered by way of the light receiver  12 , provides a means of determining the instantaneous density values of the smoke, i.e. the concentration therein of the particulate phase components. By combining flow rate and density values integrated over time, it is readily possible to provide delivery values of “tar” on a per puff basis. 
   In that the data received by the module  14  is transmitted from the module  13  by conductorless electromagnetic wave means, the unit comprised of the cigarette mounting assembly  1  and the transmission module  13  is unencumbered by tubes (associated with pressure detectors  9 ,  10 ) and wires (associated with light receiver  12 ) extending therefrom. Of course, if appropriate to particular circumstances the conductorless transmission can be first received by intermediate receiving means (not shown), the data then being transmitted to the data receiving and processing module  14  by way of conductor means (also not shown). 
   The cigarette monitoring apparatus depicted in  FIG. 2  is the apparatus of  FIG. 1  modified by the addition of further functional modules as now to be described. Parts in  FIG. 2  which correspond to parts in  FIG. 1  have been assigned the same reference numerals as those assigned for those parts in  FIG. 1 . 
   The functional modules comprised in the apparatus of  FIG. 2  which do not form part of the  FIG. 1  apparatus are as follows: 
   (i) a second transmission module  16 ; 
   (ii) a second receiving module  17 ; 
   (iii) a second display module  18 ; and 
   (iv) a data input module  19 . 
   The second transmission module  16  is operable to transmit, by conductorless electromagnetic wave means, processed data output from the receiving and processing module  14 . This conductorless transmission is preferably emitted directly from the module  16 . However, if appropriate to particular circumstances, the conductorless transmission can emanate from the intermediate transmission means (not shown), the processed data being transmitted from the module  16  to the intermediate transmission means by way of conductor means, electrical conductor means, for example, (also not shown). 
   As is indicated in the  FIG. 2  block diagram, the second transmission module  16  forms an in unit component of the monitoring assembly  2 . 
   The second receiving module  17 , which is situated at or near to the location of the cigarette mounting assembly  1 , is operable to receive conductorless transmissions from the second transmission module  16 . 
   The second display module  18  is operable to display processed data received by the second receiving module  17  from the second transmission module  16 . 
   Preferably, the second display module  18  is in unit with the second receiving modules  17 , and suitably these modules  17 ,  18  are both in unit with components of the cigarette mounting assembly  1 . 
   In the processor module  14  data derived from the pressure sensors  9 ,  10  and from the light receiver  12  are processed as per the processing effected by the processing module  14  of the  FIG. 1  apparatus. 
   The data input module  19  is operable to receive inputted data, sound and/or graphic data, and to feed the inputted data to the second transmission module  16 . Thus an operator at the location of assembly  2  can communicate with a subject who is smoking or who has just smoked a cigarette ( 6 ) via a mouthpiece ( 7 ). If, of course, inputted data takes the form of sound or sound derived data, the second display module  18  must be operable to reproduce sound. 
   The display of the second display module may offer alternative products capable of producing similar or lower smoke component deliveries. Alternatively, or in addition thereto, the display may offer a direct sales service to the consumer, enabling purchasing of goods (smoking article goods or not) directly. A business transaction may thereby take place using the invention according to either aspect of the invention. 
   The data input module  19  forms an in unit component of assembly  2 . 
   The assembly  1 , including modules  17 ,  18 , may be incorporated in a mobile phone, i.e. a mobile telephone hand piece, (this not being shown), in which case the transmission module  13  may be the transmission means of the phone or share components therewith, the receiving module  17  may be the receiving means of the phone or share components therewith and the display module  18  may be a display means of the phone or share components therewith. 
   The assembly  2  comprising modules  14 – 16  and  19  may be incorporated in or form part of a mobile phone (this not being shown), in which case the receiving module  14  may be the receiving means of the phone or share components therewith, the display module  15  may be a display means of the phone or share components therewith, the transmission module  16  may be the transmission means of the phone or share components therewith and the input module  19  is input means of the phone or shares components therewith. As will be understood, a function of the input means of the phone is to register telephone number dialling by a user of the phone. 
   The cigarette monitoring apparatus of  FIG. 3  is a variant of the apparatus depicted in  FIG. 1 . Thus common parts have been assigned common reference numerals. 
   Assembly  2  of the  FIG. 3  apparatus does not comprise as a component thereof a receiving and processing module as per module  14  of the  FIG. 2  apparatus, but rather comprises a receiving module  21 . As indicated in  FIG. 3 , the receiving module  21  is in unit with a display module  15 . The processing function in the  FIG. 3  apparatus takes place in a processing module  20  which is an in unit component of the cigarette mounting assembly  1 . Also being an in unit component of the assembly  1  is a transmission module  13 . 
   Thus in operation of the  FIG. 3  apparatus when a cigarette ( 6 ) is being smoked via a mouthpiece ( 7 ), data derived from the pressure sensors  9 ,  10  and the light receiver  12  is processed by the processing module  20  in a manner as per that described hereinabove in respect of the processing module  14  of the apparatus of  FIG. 1 . Processed data output of the processing module  20  is transmitted from the transmission module  13  in conductorless fashion and is received by the receiving module  21  and then displayed by the display module  15 . 
   As will be readily understood by versed in the art addressees, just as the  FIG. 2  apparatus has incorporated therein, vis-à-vis the apparatus of  FIG. 1 , modules  16 – 19 , these same modules  16 – 19  can be incorporated, in the same manner and to the same functional effect, in the apparatus depicted in  FIG. 3 . 
   Furthermore, if the modules  16 – 19  are so incorporated in the apparatus of  FIG. 3 , the assembly  1  of that apparatus, including with modules  17  and  18 , may be incorporated in a mobile phone. Likewise, assembly  2 , including modules  16  and  19 , may be incorporated in a mobile phone.
