Abstract: There is disclosed an ink jet printhead which comprises a plurality of nozzles and one or more heater elements 10 corresponding to each nozzle. Each heater element 10 is configured to heat a bubble forming liquid 11 in the printhead to a temperature above its boiling point to form a gas bubble 12 therein. The generation of the bubble 12 causes the ejection of a drop of an ejectable liquid (such as ink) through an ejection aperture 5 in each nozzle, to effect printing. In each nozzle, the heater element 10 requires an electrical pulse with a voltage less than 10 volts and a duration less than 1.5 microseconds, to form the vapor bubble that causes the ejection of the drop. With the realization that drive pulse voltages above, say, 12 volts are not a fixed parameter of printhead design, the benefits of low voltage printhead operation can be incorporated into a design that yields efficiencies that negate the circumstances that created the initial demand for high voltage operation.

In preferred examples, the ink container is arranged for supplying ink to a printhead; using the degassing arrangement, the formation of bubbles in the ink at the printhead can be reduced.

The real-time video concealment processes an image in a video stream, where the video stream is communicated from one video conference unit to a second video conference unit over a communication network. The real-time concealment is performed by first determining the prominent biometric features of the users image to recognize nodal points on a human face. The system then modifies the users image using a second image, so that at least one of the nodal points in the users image is covered by the second image. This modified image is then transmitted in real time to a peer in a video conference session.
