Further, the heating assembly 50 is operable to maintain the temperature in the chamber 52 within the range of about 16O 0 C to about 200 0 C.
• the lower temperature of this range i.e., about 160°, constitutes the threshold for release of volatiles from tobacco which provide the experience of smoking.
• the higher temperature of this range i.e., about 200°, defines a heating temperature below which visible smoke does not occur around the lighter.
• the lighter operates without combustion of tobacco and/or paper cigarette wrapper material.

• the lighter 20 also includes a comparatively simple control system for regulating delivery of electrical energy to the heating element 60.
• the control system also operates to control the temperature in the heating chamber 52 to the range specified above.
• the control system also functions to energise the glow light assembly when that is part of the lighter 20.
• the battery 70 may be connected in series with a first actuator 80, a timer circuit 82, and the heating element 60.
• the first actuator 80 may be operated by insertion of a cigarette into the heating chamber of the lighter, such as a switch, or a suitable conventional sensor to detect the presence of a smoking article, or a suitable conventional pressure sensor to indicate when the smoker draws upon a smoking article that has been inserted into the lighter. Regardless of the actuator type used, the actuator 80 is operable to connect the battery 70 with the timer circuit 82.
• the timing circuit begins and continues to permit electrical energy to reach the heating element 60 for a predetermined time, such as a period in the range of about 10 to about 12 minutes. During that time, the heating element 60 rapidly reaches its operating condition and heats the chamber to a temperature in the range of about 16O 0 C to about 200 0 C.

• the puff sensor circuit is operable to determine when airflow through the heating chamber begins and/or increases. When that happens, the light 40 is energized; conversely, when airflow drops or stops, the light 40 is extinguished. Thus, the light 40 simulates the operation of the coal on a burning cigarette when the cigarette is being puffed.
• a manually operable switch 86 is provided on the lighter 20. As seen in FIG. 1, the switch 86 may be located adjacent to the end of the lighter and near the protruding portion of the. smokeable object.

• the battery 70 is preferably sized to have an electrical capacity sufficient to operate the lighter 20 through multiple cycles.
• the battery 70 is most preferably capable of operating the lighter 20 for about a week for an average smoker. That could be, for example, through 100 to 150 cycles or more before replacement or recharge becomes needed. As a minimum, the battery should be able to operate the lighter 20 for at least a day, for example through about 20 cycles or more before replacement or recharge is needed.
• the battery 70 is also selected so that, when the timer 82 is initiated, the temperature of the heating chamber 52 (FIG. 3) rises to the preselected temperature or temperature range, preferably in the range of about 16O 0 C to about 200 0 C in a time period of about 10 seconds. At this time the heat in the chamber 52 acts on tobacco in the smoking article and on the flavor cartridge, if present, to begin releasing volatile vapors from the tobacco or tobacco flavor extract cartridge.
• the temperature of about 160 0 C is preferred since, below that temperature, volatile vapors may not be released.
• the temperature of about 200 0 C is also preferred since higher temperatures may give rise to visible smoke. By keeping the temperature in the chamber 52 below this value, visible smoke is essentially avoided.
• the temperatures defining the range end points allow for some variation due to operation of the temperature control, introduction of cooler air during puffing, responsiveness of the temperature control to ambient temperature changes, and similar factors. Generally speaking, these end point temperatures can be evaluated as time averages over the period of time that the timer 82 energizes the
• the timer circuit 82 (FIG. 5) preferably energizes the heater element for a predetermined time period, preferably in the range of 10 to 12 minutes. This length of time will accommodate most individuals who use cigarettes as the smoking article. The time period is selected to ' be longer that the length of time the typical smoking article to be smoked with the lighter would burn if used in the conventional way of lighting the smoking article and smoking it in the conventional manner. Where the smoking article is a cigarette, the ⁇
• time period of 10 to 12 minutes substantially exceeds the time frame of 3 to 5 minutes typically involved in smoking a cigarette.

• the smoking article is a cigar
• the period of operation established by the timer may be adjusted to be significantly longer than the 10 to 12 minute period. Again, the time period would be selected to be greater than the length of time normally associated with smoking a cigar in the conventional, lighted way.
• the expected duty cycles for the battery 70 may also be different since fewer cigars than cigarettes may be consumed by smokers on a daily or weekly basis.
• a manually operable switch 86 located for example on the outside of the jacket 62 near the open end 54 of the heating chamber 52, can be actuated. When the switch 86 is activated energy again flows through the timer circuit, heating element, and temperature control, so that the smoker can continue smoking the object.
• the lighter can provide increased power to the indicator 40 to simulate the smoking experience .
• the indicator can remain on during the time the heater is maintained at the desired temperature or the indicator can be turned off between puffs.
• the puff sensor 88 and the puff-indicator 40 are used, however, the smoker of the smokeless lighter will get a visual indication when puffing occurs.
• the puff sensor 88 senses airflow into the internal end 56 of the heating chamber 52 (FIG. 3) .
• the airflow sensor may be positioned in one of the channels 30, or the central manifold 58, as desired. Normally there is very little airflow through those channels and manifold since there is no need for oxygen to support combustion of tobacco at the end of the cigarette. But, when the smoker puffs or draws air through the smoking article in the lighter 20, the puff sensor 88 (FIG.
• the optional puff- indicator indicates when the smoker is puffing or drawing air through the lighter.
• the air condenses the volatile and semi-volatile vapors of the tobacco and the flavor extracts of the flavor cartridge, when used, into an aerosol that is then drawn out of the end of the smoking article protruding from the lighter 20. That distillation aerosol looks like smoke but does not include the particulate matter, ash, pyrolytic and pyrosynthetic compounds found in conventional tobacco smoke .
• the predetermined time interval for operation of the lighter could be set to a shorter value such as, for example the time typically involved in smoking a cigarette. That arrangement could be desirable as a way to increase battery life or longevity.
• the puff sensor 88 could be used to restart the preselected time interval when a puff by the smoker is sensed.
• the preselected time interval could be as short as the typical length of time between puffs for a smoker who smokes a cigarette slowly, but the lighter would keep the heating element energized so that there would not be any interruption in the smoking experience .
• the lighter 20 discussed above can be offered as a stand- alone item, it may also be offered as a component of a kit or smoking system.
• the kit could include at least one, perhaps more, smokable articles as well as the lighter and a replaceable power supply.
• the lighter 20 can smoke conventional cigarettes. No specially manufactured cigarette or tobacco product is required. Thus, the cost to the smoker for this smoking system is thus reduced compared to other approaches where special cigarettes are required. Furthermore, the components of the lighter 20 are fabricated from inexpensive materials. For example, the electronic components are conventional elements so that the expense associated with sophisticated electronic components is avoided. All these factors contribute to an inexpensive system and an inexpensive lighter assembly.
• the system described above allows at least a portion of a cigarette rod to be heated maintained at, or heated to, a preselected temperature for a predetermined time interval.
• the preselected temperature is maintained without substantial interruption between puffs during that time interval and, in the absence of a puff, for the duration of the predetermined time interval.
• Presence of a puff during the predetermined time interval can be determined by a puff sensor.
• the puff sensor can actuate or restart the time interval to extend the smoking period.
• the lighter 20 is a smokeless device.
• the tobacco smoked in this lighter is maintained in the specified temperature range continuously. Accordingly, the smoker may take as many puffs, or as few puffs, as desired. Further, the frequency of the puffs is unrestricted and can be any frequency the smoker desires. Furthermore, since the temperature range is low, less battery energy is needed than in systems using higher temperatures.
• the lighter according to this disclosure would require, at most, minimal cleaning. And, when such cleaning is needed, it can be performed very simply.
• the air channels 30 are externally accessible and can be readily cleaned.
• the heating chamber 52 is open at one end, and is also externally accessible. To the extent it might be necessary to clean the central channel of the air manifold, that manifold may be removed from the lighter for internal access.
