Abstract: A storage assembly includes a movable assembly configured to receive and support the weight of the load. The storage assembly also includes a base assembly configured to be fixedly mounted to the load-bearing portions of the vehicle roof of the vehicle. The base assembly is also configured to support movement of the movable assembly with the load, between a load-storage position and a load-access position, when the base assembly, in use, is fixedly mounted to the load-bearing portions of the vehicle roof, and the movable assembly, in use, receives and supports the weight of the load.

Abstract: An antenna is disclosed. The antenna can include an aerodynamic surface and an antenna component comprising a structure configured to extend from the aerodynamic surface. The structure and at least a portion of the aerodynamic surface can form an antenna, such as a half double-ridge horn antenna or a half Vivaldi antenna. In one aspect, the structure can be configured to support a pod, thus integrating the antenna with a mechanical mounting structure for the pod.

Abstract: A method of manufacture of printers and printheads formed of a number of modules mounted on a chassis. The modules and chassis are formed with a number of alignment features which engage with one another to form elastic interference couplings. By arranging a number n of such couplings for each module, the variance in positional error of each module with respect to the chassis can be made significantly less than the alignment error of the alignment features themselves, by the process of Average Elastic Alignment. The elastic interference couplings can advantageously be made to form a sealed coupling for the supply of ink from the chassis to each module.

Abstract: A method and apparatus for supplying fluid to a deposition device or printhead using the through flow principle. The pressure of fluid entering and exiting the printhead is controlled directly at the printhead by respective pressure controllers, preferably a transducer and control system or a weir. The pressure controllers can be integrated together and mounted on or further integrated with the printhead. The supply system preferably forms a closed loop including a remote reservoir, and the entire system can be arranged such that the overall free surface of fluid is exposed on average to a negative gauge pressure.

Abstract: To increase manufacturing yield, an array of ejection chambers in an inkjet printer includes at least one redundant ejection chamber. For each ejection chamber, there is a possible nozzle window, and these nozzle windows overlap. The ejection chambers are tested prior to nozzle formation to identify any non-functioning chambers, appropriately positioned within the respective nozzle windows to form uniformly spaced dots on a substrate, with at least one ejection chamber.

Abstract: Printed circuit board or other tracks are formed by the deposition of liquid to form dots on a substrate from nozzles mutually spaced by a distance s. A set of n dot diameters Di=2 s(1/2+i/n), is used to produce linear tracks at one or more directions with respect to an axis X; each track having a minimum track width Tw=s(n?2)/n; and the minimum spacing of tracks along the axis X being Ts=s/n.

Abstract: An inkjet printer has ink channels extending through a body, each channel being offset relative to a central plane with respect to the adjacent channel. A manifold extends through the body, intersecting each channel to define a channel end profile. The channel end profile of one channel is substantially a mirror image of the channel end profile of the adjacent channel, so that the acoustic was refection coefficient of the boundary between each channel and the manifold is substantially equal for all channels. An inclined region of the channel end profile facilitates the formation of connecting tracks for the channel electrodes.

Abstract: The invention provides an antenna system for operation near a ground plane, for example, at or near the surface of a body of water. The antenna system includes, for example, an array of filar elements attached to one or more spiral elements. The system also includes, for example, a buoyant support and/or housing for transporting the antenna to and/or maintaining the antenna at or near the surface of a body of water.

Abstract: A nozzle plate component manufactured by forming a layer of photoresist on a substrate and selectively exposing and removing material to define an array of distinct bodies. Nickel is then electroformed around the bodies to form a plate, with nozzles subsequently formed by ablation through the photoresist. The process can essentially be repeated to form a guard structure around each nozzle.

Abstract: A drop on demand ink jet printer, has a passive component defining ink ejector chambers with respective ejection nozzles; and an actuator component comprising a body with an opening and an actuator structure located within the opening. The actuator structure is formed of piezoelectric material by molding from a slurry or vacuum forming of flexible sheets using formers that are burned away. MEMs techniques may also be employed to build the structure on a silicon wafer using a succession of masked deposition; etch back and similar process steps.

Abstract: In a fluid pumping apparatus suitable for use in drop on demand ink jet printing, a resiliently deformable chamber wall is acted upon to create acoustic waves, which in turn cause a fluid flow in a chamber outlet. The resiliently deformable chamber wall preferably includes both rigid and flexible portions. In an alternative arrangement a channel wall is provided with a region moveable in an actuation direction. An electromagnetic actuator operates under the principle of flux modulation. The invention is preferably of planar construction, manufactured using MEMS techniques.
