Definitions

  • the field of the present invention relates generally to machines usable by consumers for recovering water-inundated wireless telecommunication handsets and, more particularly, to self-service machines and methods for returning cellphones and other handheld wireless telecommunication devices (hereafter referred to as "handsets") to proper and complete working condition after the handsets have been exposed to excessive water or other electrically-conductive liquids.
  • handsets cellphones and other handheld wireless telecommunication devices
  • any and all causes of such overexposures to liquid are generally referred to as “immersions,” and handsets that have been subject to such immersions are generally referred to as “inundated handsets,” and processes for saving, salvaging, drying, restoring or remediating inundated handsets and/or data stored thereon from potential permanent loss or damage are generally referred to as "rescue" of such handsets.
  • inundated handset batteries should be removed as soon as possible after inundation in order to avoid further damage, and various ways have been suggested to ensure the handset electronic components are completely dry before installing new batteries, but known techniques require lengthy periods of time - usually several days to be safe.
  • Popular rescue techniques involve towel drying, tilting and shaking out as much water as possible before placing the inundated handset in a bag or envelope together with rice or some other form of desiccant to absorb moisture for a day or two. Then the handset can be toweled, tilted, and shaken again to ensure no more water comes out before attempting to turn it on again.
  • Victims might try leaving it with a service desk at their local wireless carrier store, but the prospects are too speculative to be practical, not to mention that service desks often just try the same options that the victim had, albeit at a level allowing the handset to be more disassembled in order to further aid the drying process.
  • the result means a victim still has to wait for an extended period of time with only a small chance for a successful rescue.
  • Basic objectives of the present invention are to provide a fast and effective drying system and/or method for inundated handsets.
  • Related objectives include providing an easy, reliable, rapid, and affordable use to partially or completely salvage inundated handsets and the data stored thereon.

By combining both thermal and pressure forms of energy, subsystem 110 does not necessarily require as great of a magnitude of either one in order to achieve rapid yet adequate drying. Hence, subsystem 110 preferably is designed to achieve a target magnitude of more than five-hundred but less than seven-hundred-sixty mmHg subatmospheric in chamber 60.
  • subsystem 110 is able to perform with a dwell time of less than an hour while still being reliably effective at removing substantially all water moisture from inundated handset 100.
  • subsystem 110 is capable of delivering subatmospheric pressures of more than six-hundred mmHg subatmospheric in closed chamber 60 such that the thermal energy delivered can create temperatures of no more than 150° F or, more preferably, 120° F or 125° F, in the atmosphere within chamber 60, thereby minimizing the risk of material thermal damage to components of handset 100.
  • Other preferred embodiments are specified with components of subsystem 110 such that the negative pressure subsystem is capable of delivering subatmospheric pressures of more than six-hundred-sixty-five mmHg subatmospheric to chamber 60.
  • subsystem 110 includes a diaphragm pump 118 that is operable to achieve 29.6 inHg (twenty-nine and six- tenths inches of mercury), which is more vacuum than seven-hundred-fifty mmHg subatmospheric. While oil-less pumps may be used, a particularly preferred embodiment of system 10 incorporates a two-stage, 1.5 cubic foot per minute pump for pump 118, which preferably runs on 120 VAC. Low-noise pumps are also preferred, although low-noise characteristics are not necessary for most aspects of the invention.
  • Negative pressure subsystem 110 principally includes the vacuum pressure string that is operatively connected to tubing 111 that extends from port 91 of chamber 60. Aside from portions of the control logic which is part of controller 200, negative pressure subsystem 110 preferably includes at least the following components: two pressure transducers 112, 116, a pneumatic line dryer 113, a normally-closed valve 114 actuated by powered actuator 115, an accumulator tank or bottle 117, pump 118 connected to serve as a vacuum pump, and conventional sealed connectors on tubing 111 between as much. With the possible exception of accumulator tank 117, each of those individual components are preferably off-the- shelf pneumatic components connected in a conventional manner for creating, sustaining and conveying subatmospheric pressure.
  • the accumulator tank 117 may be available off the shelf, but it can be formed with any substantially rigid and air tight enclosure that is sufficiently strong for its purposes and is shaped to fit within the desired space in housing 11.
  • the primary purpose of accumulator tank 117 is to accumulate subatmospheric pressure before commencement of a rescue attempt, so that the accumulated pressure can be used to speed up the process of attaining target subatmospheric pressures within chamber 60 once rescue has been initiated by controller 200.
  • the tubing 111 is preferably a rigid pneumatic pipe or the like, although thick-walled flexible tubing may also be used for all or part of the tubing 111 in subsystem 110 in alternative embodiments, to the extent that such tubing 111 is strong and rigid enough (or internally or externally reinforced) to avoid substantial collapse when subject to the subatmospheric pressures that are characteristic of use of system 10.
  • pump 118 itself serves to deliver and maintain controlled levels of rapid-drying subatmospheric pressure to chambers 40, 60 through port 91.
  • a rapid-drying subatmospheric pressure shall be understood to be of sufficiently significant magnitude to create and sustain an atmosphere in chamber 60 that is in excess of target levels of vacuum gauge pressure, in excess of thirty mmHg subatmospheric within chamber 60.
  • the primary heating assembly of chamber 60 is preferably provided by either a heating pad 616 (such as shown in Fig. 2A) or an overhead infra-red heating assembly 80, which serves to deliver and maintain safely-controlled thermal energy.
  • the thermal energy from pad 616 or assembly 80 serves to achieve and roughly maintain a target rescue temperature within chamber 60 (preferably within +/- five degrees Fahrenheit), which correlates to an indirect target temperature within inundated handset 100.
  • Heating assembly 80 preferably includes a 100-watt halogen bulb 87 or another form of bulb producing infrared energy at adequate levels.
  • bulb 87 (or 87') may be a conventional incandescent bulb that is controlled to deliver infrared energy at sufficient operating levels.
  • the target rescue temperature is set by controller 200 to be sufficient for rapid-drying of handset 100, which is preferably substantially complete drying of all liquid moisture in handset 100 within less than two hours and, more preferably within less than an hour or less than thirty minutes.
  • the target temperature within chamber 60 is preferably at least 1 10 degrees Fahrenheit. In other embodiments, such target temperature is preferably at least 120 degrees Fahrenheit, but no more than 130 degrees Fahrenheit, particularly where components of handsets 100 are more susceptible to material thermal damage. Some alternative embodiments are able to achieve and sustain 125 degrees Fahrenheit or greater, while thermal controls are included to avoid the risk of sustained temperatures in the atmosphere of chamber 60 in excess of approximately 150 degrees Fahrenheit.
  • the maximum temperature in the atmosphere of chamber 60 is controlled to be less than the temperature at which typical inundated handsets 100 would sustain permanent material damage (i.e., melting, warping and/or other damage) if such handset 150 were to be held at that level of temperature for thirty minutes.
  • a thermal sensor 140 is preferably mounted in a wall 63 of chamber 60 to monitor the temperature of the atmosphere in chamber 60 to allow controller 200 to avoid excessive temperatures.
  • a thermally-conductive goop is used around the temperature sensor 140 to make a thermal bridge to the thermally-conductive wall 63 of chamber 60, which increases the accuracy and effectiveness of sensor 140 considering air at very low pressures tends to be a partial thermal insulator.
  • Some embodiments utilize a combined temperature and humidity sensor for sensor 140.
  • sensor 140 is or includes a thermostat, preferably a 125 degree bimetal thermostat.
  • sensor 140 has a higher temperature characteristic, preferably 140 or 150 degrees Fahrenheit, but the actual sensor 140 of such a thermostat is combined with a selectively variable resistor to enable reduction and other adjustment of its temperature reactions and, hence, adjustment of the maximum temperature permitted in chamber 60.
  • Heating assemblies of system 10 preferably include a resistive heating element and/or a flexible silicone heater assembly 130. Particularly when a flexible silicone heating pad is used, the pad is preferably oriented on the bottom of the chamber to serve as a support surface on which the handset 100 can be placed. Conductive heating assemblies such as a silicone heating pad provide a highly controllable mode of delivering thermal energy to handset 100 as well as to the atmosphere in chamber 60 that comes in contact with the heating elements. When combined with other forms of generating thermal energy, the result achieves multimodal heating of the handset 100. For these purposes, "multimodal" energy transfer is understood as being characterized by delivering such thermal energy from more than one thermal source and/or more than one type of thermal source.
  • user interface panel 30 preferably includes both a pre-printed graphic display 31 and one or more types of powered user interface modules incorporated therein for communicative interaction with user 150.
  • interface modules include a graphic user interface 32 controlled by its own control module with interaction of controller 200.
  • Graphic user interface 32 is preferably either in the form of a touchscreen and/or in the form of a screen display controlled to be coordinated together with soft-programmable button selectors 33 and 34.
  • additional data entry keys 36 are also preferably included, as is credit card reader 35 and printer 37 (represented by a slot in Fig. 1).
  • Control of the operation of system 10 is relatively automated and managed generally by logic controller 200 which, for purposes of this description, is referenced in a simplified and combined form to include corresponding power distribution modules and is referenced alternately as either “controller 200" or “logic controller & power distribution modules 200,” or the like.
  • logic controller 200 As illustrated in the flow of Fig. 5, once power to the system 10 is turned ON” through plugging in the power cord 12 and, preferably, through actuation of a power switch (not particularly shown) at initiation step 201 , the automatic controller 200 directs the preparation of each negative pressure system 110 to a state of readiness for the next rescue attempt, while also monitoring user interface panel 30 for attempts by user 150 to interact with system 10.
  • the general readiness step is indicated as step 210, specifically including readying the GUI 32 and activating pump 118. Readying of GUI 32 involves, more particularly, controlling relays and the like to distribute operative power to panel 30 and thereby initiate any dedicated user interface processors associated with panel 30.
  • Preparation of negative pressure system 110 particularly includes energizing and actuating pump 118 to begin reducing pressure in accumulator tank 117. While valve 114 is normally closed, virtually all pressure reduction by pump 118 is therefore directed into tank 117, while controller 200 monitors the progress toward achieving an adequate negative pressure in tank 118 through feedback from pressure transducer 116, which is in open communication with tank 117.
  • the target subatmospheric pressure to be attained at transducer 116 for this readiness preparation (for reference, the "target accumulator pressure”) is preferably significantly more negative than the operative subatmospheric pressure to later be targeted in chamber 60 during a rescue attempt (for reference, the "target rescue pressure").
  • the target accumulator pressure is at least twice the gauge magnitude of the targeted rescue pressure.
  • controller 200 As controller 200 continues managing preparation of system 10, it continually checks readiness at query step 202 in Fig. 5. Until controller 200 determines at query 202 that both the user interface panel is ready and the target accumulator pressure is attained, controller 200 will continue causing a "Please Wait" prompt to appear on GUI 32. Additionally, GUI 32 may display a recommendation for user 150 to consider a distilled water pre-wash of the inundated handset 100 in order to flush out any non-water solutions (such as soda, seawater or toilet water) in order to help remove bi-salts or materials that might increase the boiling point or not evaporate as readily as pure water.
  • non-water solutions such as soda, seawater or toilet water
  • some alternatives might include a bottle (or other source) of other liquid having known vaporization pressure characterizations that flushes out and replaces the liquid in the inundated handset 100, such that the other liquid preferably has a pH that is not harmful to standard handset electronic circuitry and components (an "approximately-neutral" pH), and the other liquid has a boiling point temperature less than that of distilled water.
  • processor 200 advances its query level to query step 204.
  • Query step 204 is represented simply as "Rescue Activated" in Fig. 5.
  • the decision at step 204 is typically much more involved with preferred embodiments. For instance, to determine whether rescue is activated, preferred embodiments direct user 150 through a series of automated prompts, queries and disclaimers on user interface panel 30, partially in order to make sure user 150 understands the risks and prospects for use of system 10.
  • controller 200 determines that rescue has not been activated, a prompt appears on user interface panel 30 to encourage user to take actions so that rescue can be activated, or otherwise ask the user to "please wait" while query step 204 is repeated. Once controller 200 determines that rescue has been activated, processor 200 advances its query level to query step 212.
  • Query step 212 is intended to determine principally whether the corresponding chamber 40, 60 is adequately sealed for a rescue operation. Although more sophisticated seal verifications may be used also or in the alternative, query step 212 preferably looks at feedback from door closure switch 73 and, if switch 73 indicates door 70 is fully closed, then system 200 presumes that the chamber is adequately sealed. Although not required for all aspects of the invention, alternative embodiments also use other performance indicators to alert users (or service personnel) of inadequate seals if pressure levels are not responsive enough during actual rescue processes also. Analogous pressure tests may be part of the "Chamber Sealed?" verification process at step 212.
  • controller 200 determines that the respective closure switch 73 is not in a door-fully-closed state, then controller 200 continues to cause prompts to user 150 directing user 150 to close door 50 or 70 (or the associated latches 21 , 22) or to otherwise achieve a sufficiently sealed chamber at step 212.
  • controller 200 causes system 10 to initiate a corresponding rescue attempt at step 214.
  • initiating a rescue attempt at step 214 involves commencing a rescue and then controlling the components of system 10 to rapidly achieve and then maintain (or hold) the target rescue atmosphere in the sealed chamber 40, 60 that holds handset 100.
  • the target rescue atmosphere preferably includes maintaining a combination of a target subatmospheric pressure and a target temperature in the corresponding rescue chamber 40, 60.
  • Commencement of rescue itself involves simply energizing at least one thermal source 80, 130 and causing actuator 115 to fully open valve 114, to thereby open chamber 60 to the subatmospheric pressures accumulated in tank 117.
  • valve 114 may also be used as valve 114, to enable more sophisticated initiation and maintenance of target rescue pressure. In most embodiments, sustaining the target rescue atmosphere in the corresponding chamber 40, 60 are somewhat more complicated than just initiating rescue.
  • Sustaining the target rescue atmosphere in chambers 40, 60 involves controlling both pressure and temperature therein, preferably through feedback control achieved with signals from pressure transducer 112 for assessing pressure, and with signals from Temperature & Humidity (T&H) transducer 140 for assessing temperature.
  • T&H Temperature & Humidity
  • thermal energy is preferably provided from multimodal sources
  • overall control of temperature may involve modulation of only one of those sources such that one source provides a predetermined level (or profile) of thermal energy throughout the rescue attempt, whereas the other thermal source is modulated either through alternating its power distribution On and Off as appropriate, or through proportionally controlling the amount of thermal energy produced by the corresponding thermal source by varying that level of power to that source.
  • the infra-red source 87 remains fully energized throughout the rescue attempt, while the level of energy provided to resistive heating element 130 is varied.
  • the profile for controlling energy to resistive heating element 130 is maximized until the temperature monitored at thermal transducer 140 is within a first margin of the target rescue temperature.
  • controller 200 distributes gradually less electrical energy to thermal source 130 as the atmospheric temperature continues approaching the target rescue temperature, with the level of energy being reduced in relation to how close the margin of separation from the target rescue chamber.
  • the resistive heating element 130 also preferably includes a thermocouple switch tied to platform 65, preferably at a location that is at least a quarter-inch away from the point of contact between platform 65 and resistive element 130.
  • a thermocouple provides the added safety measure of ensuring, irrespective of the atmospheric temperature in chamber 60, that the actual temperature of platform 65 does not exceed a temperature that would cause melting or cosmetic or other damage to outer surfaces of most known handsets 100.
  • system 10 preferably couples atmospheric thermal feedback control together with surface temperature feedback control, in addition to subatmospheric pressure feedback control and the other controls of system 10.
  • resistive element 130 is preferably positioned relatively near to and lower than the atmospheric transducer 140, such that thermal transducer 140 tends to be somewhat sensitive to atmospheric thermal energy rising or radiating from resistive element 130.
  • controller 200 controls the thermal and negative pressure subsystems 110, 80 and 130 to (1) cause the atmospheric conditions in chamber 60 to rapidly approach the target atmosphere levels, and (2) then hold or sustain those atmospheric conditions within a relatively close margin of those target levels.
  • a condition is preferably held or sustained for the duration of a predetermined time that is long enough to completely dry the electronic components of most handset models currently in production, assuming they were inundated.
  • a predetermined time is a standard length of time that is less than two hours in duration and, preferably, approximately thirty minutes in duration.
  • controller 200 preferably is programmed to control the therapy to last for that duration.
  • controller 200 also monitors the humidity in chamber 60 with a humidity sensor 140.
  • Humidity sensor 140 may be any type of humidity transducer, but is preferably of the type that monitors both temperature and humidity. With its transducer surface positioned in (or in direct communication with) the atmosphere of the sealed space inside chamber 60, wire leads from sensor 140 are connected to convey characteristic information (either analog or digital) about the temperature and humidity of that sealed atmosphere to controller 200.
  • controller 200 is able to validate with reasonable reliability whether the rescue attempt is being successful or, at the end of the duration of a rescue attempt, whether it has likely been successful, by determining whether the remaining humidity (i.e., moisture) in the sealed atmosphere is lower than a predetermined threshold.
  • a predetermined threshold is preferably set to be less than five percent. The predetermined humidity threshold is preferably set based on the determination that, if the humidity in chamber 60 is less than the threshold amount after handset 100 has been in sealed chamber 60 for the duration of one drying session (typically about thirty minutes), then any significant water in inundated handset 100 has already been removed.
  • controller 200 continually monitors the humidity and subatmospheric pressure in chamber 60 to ascertain if target conditions have been achieved.
  • the target conditions are achieved either by (1) the humidity in chamber 60 dropping below a target humidity (which can be calibrated for dry conditions), and/or (2) reaching a target subatmospheric pressure in chamber 60, where the target subatmospheric pressure is greater than the boiling point for water at the controlled target temperature of chamber 60.
  • controller 200 Whenever the humidity in chamber 60 is below the threshold, and/or the target subatmospheric pressure is reached or exceeded, controller 200 preferably causes a green light on user interface panel 30 to blink regularly, as an indicator to user 150 that the rescue attempt in process appears to be achieving a successful rescue.
  • the controller 200 in other embodiments use algorithms to process data from other types of sensors (i.e., other than a humidity sensor 140) to validate with reasonable reliability whether the rescue attempt is likely being or likely has been successful at the end of the duration of a rescue attempt.
  • the system 10 is calibrated such that the controller can compare the actual time required to achieve the target level of negative pressure to an amount of time that is calibrated for achieving such target in the absence of all liquid moisture.
  • controller 200 is programmed to validate actual absence of liquid water in the event the actual time for target pressure is equal to or less than such a pre-calibrated amount of time.
  • Such pre-calibrated amount of time is approximately the amount of time required to reach pressure targets for the same pump settings when a completely dry phone is in the chamber, although a slight margin of time is added to that in order to allow for imperfections.
  • controller 200 is able to validate with reasonable reliability whether the rescue attempt is being successful even without a humidity sensor.
  • controller 200 then discontinues the vacuum and thermal input into chamber 60.
  • controller 200 then initiates a second verification cycle to confirm that, from a standard atmospheric pressure state (i.e. after the chamber 60 is vented), it takes less than, or approximately equal to, an expected time to re-achieve the target subatmospheric pressure.
  • This "expected time” can be calibrated (either at manufacturing or periodically during preventive maintenance) by running dry handsets through the system 10 and confirming the amount of time that it takes chamber 60 to reach the target subatmospheric pressure with a dry handset.
  • the expected time is approximately two minutes, although alternative embodiments may have different expected time values, such as less than five minutes or less than one minute (as two examples).
  • a green light or any alternative indicator on user interface panel 30 is caused to change to a constant steady illumination state (or the equivalent) to indicate to user 150 that the rescue attempt appears to have been successful.
  • controller 200 determines at query step 219 that the target conditions have not been achieved, then the user interface preferably advises user 150 accordingly and prompts user 150 to decide whether user 150 desires to have another rescue attempt for the handset 100. If the user selects the affirmative option, then the entire process repeats. If the user instead chooses not to have another rescue attempt, then controller 200 discontinues the process and provides an audible, visual and/or printed warning that the inundated handset still appears to have water inside and that re-installing the batteries in the handset may cause permanent damage to handset 100 and/or loss of the data stored therein. If user 150 decides not to have another rescue attempt, or if the rescue attempt was successful, the system 10 reaches final step 228 and stops.
  • user interface panel 30 shows a final message to user 150 at final step 228, which may thank user 150 for using system 10; ask user 150 to come again; notify user 150 that the system 10 is now shutting down; provide user 150 with additional information for keeping their handset 100 safe; a message that benefits the retail store where system 10 is located; or any other message. While in some embodiments the system 10 will shut down at final step 228, in other embodiments, the system 10 remains powered on and ready for the next rescue attempt to speed up the process, which would be particularly useful in situations where there are multiple users 150 waiting to use system 10.
  • controller 200 controls a release - i.e., venting - of the target pressure conditions in chamber 60. Venting is performed, most notably, upon completion of a rescue attempt, to thereby allow easy opening of the door to chamber 60.
  • the vent valve may be included in the pneumatic string of subsystem 110 in alternative embodiments, such as by using a three-way valve for valve 114 of that string.
  • vent valve 121 is shown in hidden line, behind the far sidewall 61 of chamber 60, in a configuration to vent chamber 60 through distinct venting ports 122a- 22c.
  • valve 121 allows flow of dry air through a manifold (not shown) and into chamber 60.
  • the manifold preferably causes the venting dry air (or other gas such as dry nitrogen or argon from a dedicated source of the same) to be directed as small jets of air blowing into chamber 60 through a series of vent ports 122a-122c pointing toward the typical position where handset 100 is positioned.
  • Controlled venting in multiple cycles also maximizes removal of moist gases from chamber 60, preferably by plumbing the feed line for valve 121 into a location adjacent to, or preferably directly above, thermal subsystem 80. With the feed line for valve 121 so positioned, the air used for venting is more likely to be relatively hot and dry. Moreover, by venting such relatively hot and relatively dry gas into chamber 60 at intervals, the most rapid amount of drying can be achieved. [00102] Such a venting process is preferably automatically repeated under control by controller 200 at least twice during a given rescue attempt to further enhance drying, to cause circulation of vented dry gas through directed cross-flow, and to flush more moisture out of handset 100.
  • vent valve 121 also serves as a way to jet air through the small vent holes 122a-122c directly on the handset 100 before starting a second rescue attempt.
  • Alternative devices such as miniature fans may also be incorporated in alternative embodiments to enhance movement of moisture out of chamber 60.
  • vent valve 121 is a normally-open valve such that it is closed when power is distributed to operate a rescue attempt and such that it opens in the event of a power failure, to ensure access to a handset left in chamber 60.
  • the GUI 32 will monitor the relative humidity within the chamber and either after a predetermined amount of time or when the relative humidity falls below a predetermined threshold, the system will shut off and the user may then retrieve the rescued handset.
  • the controllers detect that the relative humidity has fallen below the predetermined threshold, that detection becomes an interrupting event that interrupts the rescue cycle before the preset time is complete.
  • the cycle may be stopped either upon the expiration of a predetermined amount of time or upon reaching a humidity level below a predetermined threshold, either of which causes the system to stop the controlled operation of the rescue attempt.
  • the controllers cause several steps to occur before releasing the latch mechanism and allowing the door to be opened. Such several steps include (i) causing outside air to be vented into the chamber in order to reverse the vacuum effect, (ii) discontinuing power to any heating mechanism so that it is shut off, (iii) discontinuing power to the vacuum pump(s), and (iv) then releasing the locking or latching mechanisms which have kept the rescue chamber door closed and sealed.
