Abstract: The present invention relates to an endless conveyor for transporting products, for example packaging units, along a transport path in a transport direction T, wherein the conveyor comprises: ?freely rotating supporting rollers (2) which extend substantially perpendicular to the transport direction, which are connected at both ends to conveyor elements (3), and which form an endless transport surface, and ?flights (4), connected to the conveyor at well-defined positions, which with a control are movable to and away from a carrying position above the transport surface, wherein, after such carrying position has been taken up, a product present on the transport surface is carried along in the transport direction T, wherein the flights comprise strip-shaped thresholds (41) which, from a rest position below at least the transport surface, can be moved up between the rollers to the carrying position. Suitable to carry and buffer along products over an incline and thus transport them.

Abstract: Devices and techniques that include use of a capacitive sensor to permit an OVJP print head to orient itself relative to conductive or dielectric traces on a printing substrate are disclosed. Such a sensor enables real-time measurement and closed-loop control of print head position with respect to substrate traces. This enables, for example, micron scale resolution in a dimension transverse to printing while permitting both the substrate and movement of the OVJP tool to scale to larger sizes than are achievable using conventional techniques and systems.
