A sprinkler head of visual identification is disclosed. A housing includes a circumference wall, a cap enclosing the circumference wall, and an aperture member alternatively formed on the cap and the circumference wall for dispensing water. A first visual portion is arranged on the circumference wall of the housing and corresponds with the aperture member. A second visual portion, which is visually different from the first visual portion, is arranged on the circumference wall and adjoins the first visual portion. The first and second visual portions constitute the circumference wall of the housing together, a visual differentiation of the first recognition portion and the second one is offered in accordance with the arrangement of dissimilar art elements.

A paint gun for atomizing (in particular by way of compressed-air-assisted atomization) and applying a coating material such as a paint has a material-guiding part, a non-material-guiding part, and a transmitting and/or receiving device for wireless signal transmission. In order to increase the functional reliability and provide optimal operability in the environment in which the coating material is applied, the transmitting and/or receiving device for wireless signal transmission is arranged at a distance from the material-guiding part and is associated with the non-material-guiding part. Alternatively or additionally, an increased functional reliability is achieved by designing the transmitting and/or receiving device for wireless signal transmission in accordance with two different radio standards. Furthermore, a material application system comprising such a paint gun as well as a method for operating same are described.

The present disclosure is directed to a fluidic ejection device configured to detect whether one or more nozzles of the fluidic ejection device is in a normal state, a blocked nozzle state, or an accumulated fluid state. The fluidic ejection device includes an optical blockage detector having a light emitting device configured to emit a light signal, and a light sensor configured to detect the light signal. The optical blockage detector detects the normal state, the blocked nozzle state, and the accumulated fluid state based on the detected light signal.

Removable and replaceable outlets for point-of-use showers or faucets, filter devices, and methods and systems including the outlets and/or filter devices, are disclosed.

A drive circuit is provided for controlling a solenoid valve having a solenoid coil. The drive circuit includes a first semiconductor device, a flyback circuit, and a processor. The first semiconductor is coupled in series with the coil and is controlled by a gate signal to energize the coil. The flyback circuit is in parallel with the coil and includes a series-coupled second semiconductor device and a diode. The second semiconductor is controlled by a flyback control signal to enable the flyback circuit when the first semiconductor is controlled by the gate signal to hold the valve open. The diode has a low forward voltage to slow decay of a current conducted through the coil. The processor generates the gate signal to control the first semiconductor and to reduce a duty cycle of the gate signal when the flyback circuit is enabled to reduce power consumption by the coil.

Organic light-emitting device manufacturing method performed by using a manufacturing apparatus placed where light from outside is blocked and a lighting device emitting light constituted of light components with wavelengths of 500 nm or longer is placed. The manufacturing apparatus includes a main body having an ejector ejecting ink containing organic light-emitting material and a light-transmissive tube forming at least part of a transport path connecting a tank containing the ink and the ejector. The method includes: removing the ink inside the transport path when a total exposure amount ET (lux×hours) satisfies ET≧α×17500 where a is a constant satisfying α≧1. ET is a product of E denoting light amount (lux) from the lighting device to which the tube is exposed and T denoting time amount (hours) over which the tube is exposed to the light from the lighting device.
