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.

Abstract: A cartridge servicing case for servicing a fluid jet cartridge carrying a composition includes a case body having a pocket that is sized to receive the fluid jet cartridge. A moveable cartridge servicing member is moveable relative to the case body. The moveable cartridge servicing member includes at least one of a wiping element and a capping element carried by the moveable cartridge servicing member. The pocket is arranged and configured to expose nozzles of the fluid jet cartridge received by the pocket to the moveable cartridge servicing member for a servicing operation using the at least one of the wiping element and capping element.

Abstract: Bio-based glacial acrylic acid, produced from hydroxypropionic acid, hydroxypropionic acid derivatives, or mixtures thereof and having impurities of hydroxypropionic acid, hydroxypropionic acid derivatives, or mixtures thereof, is polymerized to poly(acrylic acid) or superabsorbent polymer using the same processes as petroleum-derived glacial acrylic acid.

Abstract: Included are embodiments for providing a service station interface. Some embodiments of a system include a service station for receiving a handheld jet dispensing apparatus in a service compartment of the service station and a memory component. The memory component may store logic that, when executed by a processor, causes the system to determine if a maintenance function is to be implemented on the handheld jet dispensing apparatus, in response to determining that the maintenance function is to be implemented, determine if the service station is closed, and if the service station is closed, engage an interface function of the service station during the maintenance function, wherein the interface function is related to accessing the service compartment. In some embodiments, the logic causes the system to determine that the maintenance function has ended and, in response to determining that the maintenance function has ended, disengage the interface function.

Abstract: An interchangeable servicing cassette is sized to be removably received by a servicing portion of a service station for servicing a handheld jet dispensing apparatus comprising a fluid jet cartridge carrying a composition and a camera for capturing an image of a surface. The servicing cassette includes a moveable actuation member configured to be moved by an actuator of the docking station relative to the fluid jet cartridge of the jet dispensing apparatus. At least one of a wiping element, a calibration element and a composition receiving element is carried by the moveable actuation member.

Abstract: Lactic acid, lactic acid derivatives, or mixtures thereof are dehydrated using a catalyst and process to produce bio-acrylic acid, acrylic acid derivatives, or mixtures thereof. A method to produce the catalyst is also provided.

Abstract: A micro electromechanical ink jet printing system that has a cartridge having a body that defines a core, and a die that contains one or more nozzles. There is a treatment composition contained within the cartridge core. The system further includes a CPU that is programmable and can control the application of the treatment composition from within the cartridge core, through the one or more nozzles to human skin. Typically, the treatment composition will contain a skin treatment ingredient selected from the group consisting of particles, vitamins, yeast and yeast extracts, skin care actives, dyes, colorants and mixtures thereof. There may optionally be provided a bladder or foam block disposed within the cartridge core for suspending and regulating the flow of the treatment composition. The systems of this invention may include an applicator having an applicator head having one or more applicator nozzles which may be in a array.
