Description

FIELD OF THE INVENTION

The present application relates generally to systems and methods for providing a service station routine and specifically to maintenance and locking mechanisms that may be utilized for a handheld device service station.

BACKGROUND OF THE INVENTION

Inkjet devices, piezo and thermal, are common for both personal and industrial printing purposes. Most commonly, such devices are found in consumer homes as a means to create high quality prints and photos. In consumer applications there is a high need for reliable performance with minimal effort from the consumer. Because of this, all existing consumer printing devices contain sophisticated processes for maintaining a high print quality. It is common for consumer inkjet printing devices to contain thousands of individual nozzles with each nozzle as small as 5-20 microns. Additionally, most inks in such devices are volatile and are prone to drying out quickly when exposed to air. Due to the small and numerous nozzles and fast dry times, it is difficult to keep all nozzles working properly over the course of thousands of printed pages and potentially long periods of time between prints. Due to these requirements, much effort has been taken by printer manufacturers to devise mechanisms that keep the printing nozzles performing well. Most consumers have no knowledge of all of the servicing that occurs to ensure good print quality as it occurs automatically.

While servicing nozzles of a stationary inkjet printing device is known, there has been little need to consider how to automatically service inkjet nozzles for a handheld printing device. Handheld inkjet printing devices are uncommon and usually used for industrial tasks like labeling boxes during manufacturing. In such cases the servicing needs of nozzles is performed manually. These handheld printers require removal of the inkjet cartridge after each use and manually wiping and capping the printhead. For such industrial applications this may be acceptable. However, there has not been the need to create an automated servicing solution for handheld printing devices.

SUMMARY OF THE INVENTION

Included are embodiments for providing a service station routine. Some embodiments of a system include a service station for receiving a handheld jet dispensing apparatus and a memory component that stores logic. When the logic is executed by a processor, the logic may cause the system to, in response to the service station receiving the handheld jet dispensing apparatus, identify the handheld jet dispensing apparatus, where identifying the handheld jet dispensing apparatus includes determining a time of a previous maintenance to the handheld jet dispensing apparatus. In some embodiments, the logic causes the system to determine whether the time of the previous maintenance meets a predetermined threshold, in response to determining that the time of the previous maintenance meets a predetermined threshold, determine a desired maintenance routine to execute and execute the desired maintenance routine, and record a current time as the time of the previous maintenance.

Also included are embodiments of a method. Some embodiments of the method include receiving a handheld jet dispensing apparatus at a service station, determining whether the handheld jet dispensing apparatus is registered, and in response to determining that the handheld jet dispensing apparatus is registered, determining a time of a previous maintenance to the handheld jet dispensing apparatus. Some embodiments of the method include determining whether the time of the previous maintenance meets a predetermined threshold, in response to determining that the time of the previous maintenance meets the predetermined threshold, determining a desired maintenance routine to execute and execute the desired maintenance routine and recording a current time as the time of the previous maintenance.

Also included are embodiments of a non-transitory computer-readable medium. Some embodiments of the non-transitory computer-readable medium include logic that, when executed by a processor, causes a device to, in response to the service station receiving a handheld jet dispensing apparatus, identify the handheld jet dispensing apparatus, where identifying the handheld jet dispensing apparatus includes determining whether the handheld jet dispensing apparatus is due for maintenance. In some embodiments, the logic causes the device to, in response to determining that the handheld jet dispensing apparatus is due for maintenance, determine a desired maintenance routine to execute and execute the desired maintenance routine on the handheld jet dispensing apparatus while the handheld jet dispensing apparatus resides in the service station and record data regarding the handheld jet dispensing apparatus and the maintenance.

FIG. 4 depicts a flowchart for imparting energy into a reservoir of the handheld jet dispensing apparatus 102, according to embodiments described herein. As illustrated in block 450, the service station 104 may receive the handheld jet dispensing apparatus 102 and identify the device that was received. The handheld jet dispensing apparatus 102 may be configured to communicate with the service station 104 to identify itself, and/or provide other information. The other information may include date of last service, type of last service, malfunctions that have occurred since last service (or at other times), etc. With this information in block 452, the service station 104 may determine the previous maintenance that the handheld jet dispensing apparatus 102 has received. In block 454, the service station 104 may determine whether a fluid homogeneity of the solution substantially matches a predetermined fluid homogeneity. Specifically, the solution in the handheld jet dispensing apparatus 102 may be configured with one or more ingredients for treating skin imperfections, applying solutions to clothing, applying solutions to surfaces, and/or applying solutions to other items. As discussed above, the solution may take any of a plurality of different forms, depending on the particular treatment being performed. Accordingly, if the handheld jet dispensing apparatus 102 and/or the reservoir are stationary or otherwise unused for a period of time, the solution may settle and/or the ingredients that make up the solution may separate. As a consequence, the solution may lack the desired fluid homogeneity for use in the handheld jet dispensing apparatus 102. Thus, the service station 104 (and/or the handheld jet dispensing apparatus 102) may include one or more sensors for determining the fluid homogeneity of the solution.

As an example, the handheld jet dispensing apparatus 102 may include a timer to determine movement, use, and/or timing of movement or use of the handheld jet dispensing apparatus 102 to determine whether the time exceeds a time that would change the fluid homogeneity of the solution beyond a desired level (which may vary, depending on the particular solution). Similarly, some embodiments may be configured with an opacity sensor or light sensor to determine whether the solution has the desired opacity. If the opacity of the solution is not at a desired level, the service station 104 may determine that the fluid homogeneity does not meet a predetermined fluid homogeneity. Other sensors and determinations may also be made.

As another example, if the cartridge is a new cartridge that has never been used, some embodiments will expend specific amount of energy and length of time the energy is introduced to reach the desired fluid homogeneity. In these embodiments, an identifier on the cartridge may be accessed to determine the contents of the cartridge, whether the cartridge is new or previously used, and/or other information. If the cartridge is determined as new, a new cartridge routine may be implemented for reaching the desired fluid homogeneity. If the cartridge is used, a unique service routine may be run, based on the type of solution, time since last use, etc. In some embodiments, a number of droplets may be tracked, such that if the cartridge is determined to be used, an age from production or time since first use may signal to the user that the cartridge should be replaced. In other embodiments the contents of the cartridge will determine the type of servicing routine required for a specific formulation.

In embodiments where a cartridge stays in the handheld jet dispensing apparatus 102 for the entire duration of the life of the cartridge, service station 104 may determine a time that the handheld jet dispensing apparatus 102 (and thereby the cartridge) has been out of the service station 104. Once a predetermined threshold of time is reached, the service station 104 will to introduce a predetermined amount of energy, type of energy and time of energy to impart, based on the threshold, the solution, and/or other factors. In embodiments where the consumer is able to employ multiple cartridges in the handheld jet dispensing apparatus 102 and thereby will be removing cartridge A and inserting cartridge B, embodiments may be configured to recognize the cartridge (new, used, how many uses when last used, etc.) and determine a specific routine based on the solution in the cartridge. Some formulations will only cap and/or wipe, while others (unstable formulations-like pigmented) may require energy to be imparted to re-disperse the solution, as well as wiping and/or capping.

Returning to FIG. 4, in block 456, in response to determining that the solution consistency does not substantially match the predetermined consistency, energy may be introduced into the solution to reach the desired consistency (and/or other acceptable consistency level). As an example, imparting energy may include shaking, vibrating, spinning, flipping, introducing a magnetic field, introducing an electric field, etc. to adequately mix the solution and achieve the desired consistency. In block 458, once the fluid homogeneity reaches the acceptable level, the maintenance timer may be reset.

FIG. 5 depicts a flowchart for the service station 104 to determine when to perform a maintenance function to the handheld jet dispensing apparatus 102, according to embodiments described herein. As illustrated in block 550, a time since a previous maintenance may be determined. As discussed above, the determination may be made in response to receipt of information from the handheld jet dispensing apparatus 102. In some embodiments, the service station 104 may record a previous maintenance to the received handheld jet dispensing apparatus 102 and make a determination from that information. The maintenance may include camera cleaning, calibration, nozzle cleaning, and/or other maintenance and thus the service station 104 may make one or more determinations regarding a previous maintenance. Regardless, in block 552, a determination may be made regarding whether the time exceeds a predetermined threshold for maintenance. Specifically, the handheld jet dispensing apparatus 102 may perform optimally if calibrated, cleaned, and/or otherwise maintained according to a predetermined schedule. As there might be a plurality of different schedules, based on the type of maintenance, this determination may include checks for one or more of types of maintenance have exceeded the predetermined threshold for that type of maintenance. In block 554, in response to determining that the time exceeds the predetermined time, a predetermined maintenance routine may be implemented.

In block 754, if it is determined that the service station 104 is closed, an interface function of the service station 104 (such as a first interface function) may be engaged during the maintenance function, where the interface function is related to accessing the service compartment. In block 756, a determination may be made regarding whether the maintenance function has ended. In block 758, in response to determining that the maintenance function has ended, the interface function may be disengaged.

Depending on the particular embodiment, the interface function may include locking mechanism to prevent access to the service compartment, a visual output to inform a user of restricted access to the service compartment, a tactile output to inform the user of restricted access to the service compartment, audible indication to inform the user of restricted access to the service compartment, a timer to determine a time that restricted access to the service compartment will be removed, and/or other interfaces.
