(As cited in respect to claim 9 above). Claim 24. (Canceled) Claims 26-27. (Canceled) Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Kinoshita [US 2021/0375118] in view of Gordon [US 2008/0199354] Claim 7. (Original) The method of claim 1, wherein the target sequence of actions includes washing actions executed on a user's hands and forearms, including one or more of: rinsing the user's hands and forearms with water (the rub, wash and rinse hands, see Fig. 5, para [0038, 0039, 0040, 0043]); cleaning fingernails with a nail pick (see Fig. 5, para [0041]); scrubbing the user's hands and forearms with an iodine sponge (the rub and wash with lather soap, see Fig. 5, para [0037, 0038]); passing the user's hands and forearms through running water in a forward direction (the running water, see para [0039]); washing the user's hands and forearms in a direction from the fingertips towards the elbow (the rub and wash backs of hands and between fingers, see para [0038, 0039]). But Kinoshita fails to disclose removing jewelry and drying the user's hands and forearms with a towel. Gordon et al suggests that clean hands in restaurant settings are similarly critical to prevent the spread of disease. The FDA reports that poor personal hygiene in a food service environment is a critical area that needs immediate attention and makes the following points with respect to personal hygiene: proper, adequate hand-washing, prevention of hand contamination, good hygienic practices, hand-washing facility, convenient/accessible, and hand-washing facility, cleanser/drying device can be an air blower. (See Figs. 1-4, para [0008, 0055]). Preferably, rings, bracelets, wristwatches, and other jewelry are removed to ensure that pathogens under the jewelry are deactivated (see para [0037, 0054]). Therefore, it would have been obvious to one skill in the art before the effective filing date of the invention to add or implement the handwash includes removing all jewelry and drying hands of the subject of Gordon et al to the subject handwashing procedures 1 to 9 of Kinoshita for preventing of various bacterial or viral outbreaks causing deaths and to preventing of lost or damaged to the jewelry during handwashing. Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Kinoshita [US 2021/0375118] in view of Carrigan et al [US 2023/0343200] Claim 8. Kinoshita fails to disclose maintaining the user's elbows bent at or near a right angle; and maintaining the user's hands above the level of the elbows. However, Kinoshita teaches the nine areas 811 to 819, which correspond to procedures (1) to (9) included in the hand-washing action, respectively. Each of the areas 811 to 819 displays a description and an image of each procedure. As an example, the hand-washing action includes the following procedures (1) to (9): [0035] (1) Wet hands. [0036] (2) Apply soap. [0037] (3) Lather soap. [0038] (4) Rub and wash the backs of hands. [0039] (5) Rub and wash between fingers. [0040] (6) Rub and wash thumbs. [0041] (7) Rub and wash under fingernails. [0042] (8) Rub and wash wrist. [0043] (9) Rinse hands with running water. (See Fig. 5, para [0033-0043]). Carrigan et al suggests that in some embodiments, detection of the activity of the user of the computer system (e.g., 100, 300, 500, 600, 646, and/or 1300) includes detection of the user washing their hands (e.g., the computer system receives information from the one or more sensors (e.g., an accelerometer, a gyroscope, a motion sensor, an inertial measurement unit, and/or a direction sensor) indicating that the user is washing their hands (e.g., detected movement of the computer system is indicative of movement of the user washing their hands), and in response to receiving the information, displays a notification and/or alert that, when selected, allows the computer system to initiate a handwashing operation). Disabling the automatic detection of the user washing their hands based on the sensor measurements from the one or more sensors when the computer system is in the second mode of operation conserves battery power when the user is not likely to request the computer system to monitor and/or track hand washing, thereby increasing battery life of the computer system. (See para [0572]). In some embodiments, an air gesture is a gesture that is detected without the user touching an input element that is part of the device (or independently of an input element that is a part of the device) and is based on detected motion of a portion of the user's body through the air including motion of the user's body relative to an absolute reference (e.g., an angle of the user's arm relative to the ground or a distance of the user's hand relative to the ground), relative to another portion of the user's body (e.g., movement of a hand of the user relative to a shoulder of the user, movement of one hand of the user relative to another hand of the user, and/or movement of a finger of the user relative to another finger or portion of a hand of the user), and/or absolute motion of a portion of the user's body (e.g., a tap gesture that includes movement of a hand in a predetermined pose by a predetermined amount and/or speed, or a shake gesture that includes a predetermined speed or amount of rotation of a portion of the user's body). (see Fig. 1, para [0076]). Therefore, it would have been obvious to one skill in the art before the effective filing date of the invention to implement the angle of the user’s arm/hand relative to ground or a distance of the user’s hand relative to the ground during handwashing of Carriagan et al to the handwashing actions of Kinoshita for providing a convenient and optimum handwash to a user and to prevent of messing during handwash due to the heigh of the washer bow relative to the high of a person user. Claims 11, 12, 25 are rejected under 35 U.S.C. 103 as being unpatentable over Kinoshita [US 2021/0375118] in view of Chung [US 2018/0251964] Claim 11. Kinoshita fails to disclose wherein: the target sequence of actions includes washing a part of a user's body using water having a temperature within a designated range of temperatures, and comparing the sequence of actions performed by the user at the wash station to a target sequence of actions comprises comparing the temperature of water used to wash the part of the user's body to the designated range of temperatures. However, Kinoshita teaches that processor 101 determines that the subject has started hand-washing by detecting a start of water flow from a faucet F by a flow rate sensor installed in the faucet F or the like. (See Fig. 5, para [0044]). Chung suggests that the handwashing station 20 positioned within a bathroom along a wall 14 and beneath a mirror 12. The handwashing station 20 provides an area for the user to both wash and dry their hands by incorporating the entire handwashing process into the handwashing station 20 and automatically wets, cleans, and dries the user's hands 18 (as described further herein). As shown in FIG. 3, the handwashing station 20 provides an area for a user to wash (which may include wetting, soaping, and rinsing steps) and dry their hands 18 without leaving the handwashing station 20. Accordingly, the handwashing station 20 reduces the likelihood of water being dripped outside of the handwashing station 20 as the user washes and dries their hands 18. Additionally, the handwashing station 20 ensures that the user washes their hands 18 with soap 36 or a sanitizing liquid 38 (as shown and described further herein) and for a sufficient amount of time. Further, by consolidating washing and drying hands into an all-in-one single unit or device, the handwashing station 20 reduces the amount of required room for washing and drying hands 18 within a bathroom compared to the room required for conventional sinks, soap dispensers, and hand dryers, thereby freeing space within the bathroom (see Figs. 1-3, para [0082]). The liquid dispensing system 30 may include a water mixer in order to mix hot and cold water 34 to the desired temperature and a thermostat to ensure that the correct temperature of water 34 is being dispensed (see para [0099]). Therefore, it would have been obvious to one skill in the art before the effective filing date of the invention to add or implement the handwashing desired temperature of Chung to the handwashing water from the faucet of Kinoshita for controlling water temperature to provide comfortable to a user or subject washing hands to avoid of too cold or too hot water causing damage to their hands and skins, since the water faucet built with hot and cold water controller are well known in the water usage industries and available from the shelves. Claim 12. (Original) The method of claim 11, wherein determining that the sequence of actions performed by the user at the wash station does not satisfy similarity criteria for matching the target sequence of actions comprises determining that the temperature of the water used to wash the part of the user's body is not within the designated range of temperatures. (As discussed between Kinoshita and Chung in respect to claim 11 above and as cited in respect to claim 1 above). Claim 25. (Original) The medical system of claim 15, wherein: the target sequence of actions includes washing a part of a user's body using water having a temperature within a designated range of temperatures, and comparing the sequence of actions performed by the user at the wash station to a target sequence of actions comprises comparing the temperature of water used to wash the part of the user's body to the designated range of temperatures. (As discussed between Kinoshita and Chung in respect to claim 11 above and as cited in respect to claim 1 above). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Cohen et al discloses the display can be implemented using light emitting diodes or a liquid crystal display. In one embodiment, the messages are displayed in the form of backlit indicator icons. These universal icons can be implemented as a display sequence, i.e., each icon remains lit for a predetermined period of time, then the next icon will light up and so on. For example, the icon sequence may have the following steps: Wet hands, Apply Soap, Scrub, Rinse and Dry thoroughly (& apply sanitizer). [US 6,236,317].
