Abstract: The print head cover (83) of an electrostatic deflection inkjet printer is made of a material having an electrical surface resistivity of no more than 1012 ohms per square or an electrical volume resistivity of no more than 109 ohm metres and is electrically connected to an earth line (93, 97). This prevents build-up of electric charge on the cover (83). The resistance from the surface of the cover (83) to a place where a cover earth line (93) joins a signal earth line (97) or enters the umbilical (7) is at least 16000 times the resistance from that place to earth. This prevents an electrostatic discharge to the cover (83) disrupting the electronic circuits. The high resistance earth connection for the cover (83) avoids the need for an earthing wire braid in the umbilical (7). The cover (83) may be moulded from an antistatic or static dissipative material.

Abstract: A computer-implemented method for generating digital media tasks, authorizing digital media associated with the digital media tasks, and evaluating the digital media is provided. In an embodiment, a server computer creates a digital media task and sends it to one or more mobile computing devices. When the server receives digital media from a mobile computing device, the server computer determines whether it is authorized to provide other computing devices with access to the digital media. Determining whether the server computer is authorized to provide other computing devices with access to the digital media may comprise determining whether the server computer has current waivers for the digital media or whether supervisory computing device has provided authorization.

Abstract: In a continuous ink jet printer for use with pigmented ink, the entrance to the ink path (81), (35) from the interior of the ink tank (27) to the ink pump (31) is made up of a plurality of small inlet openings, which may be provided by nozzles 85 formed in a shroud 83 that fits around an ink filter (33) in the ink tank (27). The openings are provided at the bottom of the ink tank (27), close to the floor, and face parallel to the floor or at least partially towards it. If the ink pump (31) is driven in reverse, any ink in the ink path is driven at speed out through the inlet openings into the interior of the ink tank (27), followed by air. This tends to disperse pigment that may have settled to the bottom on the ink tank (27).

Abstract: Either during message selection in an industrial printer (e.g. ink jet or laser marking) for printing onto objects carried past it on a conveyor, or during printing, or both, a printer displays an image associated with the message proposed for printing or being printed. The image may be a picture (e.g. a photograph) of the object on which the message should be printed or the intended customer/end user or the intended use of the object on which the message should be printed. Since a human operator can usually identify an object or intended customer/use more quickly and accurately from a picture than from text, this reduces errors in message selection and/or helps the detection of an incorrect message during printing. The image may be displayed with the associated message or without it.

Abstract: A continuous inkjet printer has an ink circuit comprising an ink tank, an ink pump and a Venture suction device. The Venturi is used to suck an extra solvent or ink as required. However, if the ink tank is empty, no ink can be pumped through the Venture and so it will not develop suction and thus, cannot be used to suck in an initial supply of ink to an empty tank. A removable ink container may be connected to the ink tank or elsewhere in the ink circuit, for example, between the Venturi outlet and the pump inlet. Compressing the ink container manually will force ink into the ink circuit. When enough ink has been added, the pump will drive ink through the Venturi and suction will be generated.

Abstract: An electrostatic deflection inkjet printer has a main printer body separated by a vapor barrier into an electrical region and a fluid region. Electrically operated valves are provided in the fluid region. Control circuitry for deciding when to operate the valves is provided in the electrical region. Valve drive circuitry, for generating drive currents for the valves, is provided in the fluid region and is in data communication with the control circuitry via wiring, which may be a serial bus, that passes through the vapor barrier. This reduces the number of electrical connections that need to pass through the vapor barrier. A circuit carrier for the valve drive circuitry may be mounted on a valve block for the valves, and an electrically insulating material may cover the circuit carrier. The electrically insulating material may extend partially or wholly around the valve block.

Abstract: A non-contact printer controls the sensitivity of sensors provided upstream of a print head, to detect the approach of an object. In a calibration operation to set the sensitivity level of the sensors before a printing operation, the printer displays instructions to guide the operator and adjusts the sensor sensitivity to find detection threshold levels for a background (object absent) condition and when the object is present. The calibration results may be stored in association with data identifying the conveyor and the type of object used in the calibration operation. If the same conveyor and/or object type is used again in a later printing operation, the sensitivity level of the sensors can be set using the stored calibration results so that a further calibration operation is not necessary.

Abstract: The present invention comprises a device for strengthening, improving range of motion and/or improving flexibility in ankle joints and/or rehabilitating injured ankle joints. The device comprises a structure or frame, at least one resistance mechanism connected to the structure or frame and a support platform connected to the at least one resistance mechanism for supporting a patient's foot. Rotating, flexing, inverting and/or everting the patient's foot connected to the ankle of interest, which results in pressure applied to the support platform by the patient's foot, increases and/or decreases tension in the at least one resistance mechanism. A variety of stretches and/or strengthening and/or rehabilitating exercises may be performed with the device. The support platform is suspended within the frame on the at least one resistance mechanism and, as a result, the support platform may be rotated, flexed, inverted and/or everted in an infinite number of directions.

Abstract: The exposure of pixel lines in one or more image sensor regions is substantially synchronized. Each image sensor region is associated with a different lens in a multi-lens camera system. For a first pixel line in a first image sensor region and a second pixel line in a second image sensor region corresponding to the same portion of a field of view, the first pixel line and the second pixel line are sequentially or substantially simultaneously exposed. After exposing the first pixel line and the second pixel line, image information associated with the exposures is combined and output on the same readout line.

Abstract: Spatial resolution can be improved in multi-lens digital cameras. Each lens can have the same or similar field of view, but can be associated with different modulation transfer functions defining varying sharpness based on location within the field of view. The image information received from each lens can be combined to form an image based on the sharpness of the image information received from each lens.

Abstract: The luminance information of an image captured by a multi-lens camera system can be improved by selecting a luminance information source for each portion of the captured image. Each lens of the camera system can capture an initial image. For each portion of a final image, a corresponding initial image portion can be selected as the luminance information source. The portions of the final image and initial images can be pixels, groups of pixels, or other image portions. The luminance information from the selected initial image portions is combined to form final image luminance information. Chrominance information can also be selected from the initial images to form final image chrominance information, and the final image chrominance information and the final image luminance information can be combined to form a final image.

Abstract: Spatial resolution can be improved in multi-lens digital cameras. Each lens can have the same or similar field of view, but can be associated with different geometric distortions defining, for example, a magnification at various field of view portions. A final image can be generated based on an initial image captured by each lens. Luminance information from the magnified portions of the initial images can be combined to form final image luminance information. Chrominance information from the initial images can be combined to form final image chrominance information. The final image can be generated based on the final image luminance information and the final image chrominance information.
