A material deposition system and method is disclosed for depositing material onto raised features on a surface of a substrate. The material deposition system and method are a contact deposition or printing system and method, which employs biased rollerball to deposit the material as it travels along the substrate and over the raised features.

A dual-valve automatic calibration system comprises a primary positioner, a first secondary positioner and a second secondary positioner: the first secondary positioner and the second secondary positioner are connected with a first fluid coating unit and a second fluid coating unit, respectively; the primary positioner comprises a primary X-axis positioner and a primary Y-axis positioner; both the first secondary positioner and the second secondary positioner are connected with the primary X-axis positioner. In contrast to the prior art that a secondary positioner is installed on a primary Z-axis positioner, a dual-valve automatic calibration system contributes to promotion of positioning precision on the Z-axis and reduction of a burden imposed on the Z-axis.

A method is provided for preparing an area of the ground surface to be milled by a milling machine. Prior to performing any milling operation on the area of the ground surface, a survey vehicle separate from the milling machine is used to traverse the area. The survey vehicle detects the presence of buried obstacles with a sensor and generates a sensor output signal indicative of the presence of the buried obstacle. The sensor output signal is received in a controller which generates a sprayer actuation signal and responds to the sensor output signal. A marking sprayer is actuated in response to the sprayer actuation signal and sprays the ground surface above the obstacle with a visible marking emitted from the sprayer. Subsequently, a milling machine separate from the survey vehicle may be utilized to mill the ground surface and by observation of the visible markings the operator may avoid impacting the milling drum with the buried obstacles.

A method of depositing material on an electronic substrate with a dispensing system includes acquiring an image of a first feature of a first component and an adjacent second feature of a second component, performing a measure command to measure an actual distance of a gap between the first feature of the first component and the second feature of the second component, dividing the length of the gap into segments to determine a gap width for each segment, based on the gap width, determining a number of dots to be dispensed by the dispensing unit for each segment, and performing the dispense operation for each segment.

The various embodiments described herein include methods, devices, and systems for customizing dental care. In one aspect, an oral care agent dispenser device includes: (1) multiple chambers each configured to receive a cartridge containing a different oral care agent ingredient of a plurality of oral care agent ingredients; (2) memory configured to store an oral care agent formulation that includes one or more of the plurality of oral care agent ingredients; and (3) a dispenser positioned above an oral care agent dispensing region, the dispenser configured to dispense one or more of the plurality of oral care agent ingredients in accordance with the oral care agent formulation.

A system for circulating a sealer is provided. The system includes a circulation line, in which a sealer is circulated and a first circulation valve which is disposed in the circulation line and configured to control the circulated sealer. A supply line is branched from a front end of the first circulation valve and an applying gun which is disposed in the supply line, receives a sealer, and controls the sealer discharged to the outside through a nozzle.

A system for applying a sealer disclosure includes a supplying unit; a circulating unit; a temperature compensating unit; an applying gun; and a quantitative discharging unit. The supplying unit is configured to supply a sealer. The circulating unit is configured to circulate the sealer supplied from the supplying unit along a predetermined circulation line. The temperature compensating unit is disposed at one side of the circulation line and configured to compensate for a temperature of the circulated sealer to a predetermined temperature range. The applying gun is disposed at a front end of an arm of a robot so as to discharge a part of the circulated sealer through a nozzle. The quantitative discharging unit is configured to pressure-feed a predetermined quantity of sealer circulating along the circulation line to the nozzle.

A dispensing apparatus includes a frame having a gantry configured to provide movement in the X axis and Y axis directions, and first and second dispensing units coupled to the gantry and configured to dispense material onto a substrate. The second dispensing unit is coupled to the gantry by an automatic adjustment mechanism. The dispensing apparatus further includes a controller configured to control the operation of the gantry, the first dispenser, the second dispenser, and the automatic adjustment mechanism. The automatic adjustment mechanism is configured to move the second dispenser in the X axis and Y axis directions to manipulate a spacing between the first dispensing unit and the second dispensing. Methods of dispensing material on the substrate are further disclosed.

A fluid dispensing machine includes a frame and a fixture held by the frame. The fixture is configured to support a substrate. A positioning system is supported by the frame. A guidance system is supported by the positioning system. The guidance system has a camera viewing the fixture that is movable relative to the fixture. A fluid dispenser is supported by the positioning system and is moved by the positioning system relative to the fixture. The fluid dispenser is configured to dispense fluid onto the substrate. A controller communicates with the positioning system and the guidance system. The controller operates the positing system to control a position of the fluid dispenser relative to the fixture based on an image obtained by the camera.

A dual-valve automatic calibration system comprises a primary positioner, a first secondary positioner and a second secondary positioner: the first secondary positioner and the second secondary positioner are connected with a first fluid coating unit and a second fluid coating unit, respectively; the primary positioner comprises a primary X-axis positioner and a primary Y-axis positioner; both the first secondary positioner and the second secondary positioner are connected with the primary X-axis positioner. In contrast to the prior art that a secondary positioner is installed on a primary Z-axis positioner, a dual-valve automatic calibration system contributes to promotion of positioning precision on the Z-axis and reduction of a burden imposed on the Z-axis.
