A method and device for creating and maintaining a personalised bubble of scent, the method including: providing a wearable device including a perfume reservoir, a perfume dispenser coupled to the perfume reservoir, and a controller to dispense a volume of perfume from the device at intervals; controlling said wearable device to dispense a pulse volume of scent from said perfume reservoir at a pulse interval; and determining said pulse volume and said pulse interval to maintain a mass per unit volume concentration of said perfume above a threshold level within a defined radius from said wearable device.

A fibre reinforced composite product can be made by first forming a scaffold structure () with a set of tubes () running within the product interior, using a digital printing process. Using a carrier fluid, the tube lumens are invested with fibres and then matrix material. The carrier fluid may enter through the end of a tube connecting with an input manifold () and exit the tube radially via a capillary () which runs alongside the tube.

Method of making a composite product

A mounting arrangement for mounting a printer component to a support, using a foil including a number of mounting apertures, into which pins are inserted to provide alignment. The engagement of the pins in the aperture causes local deformation of the foil, the resulting forces acting to align the pins to an accuracy which can be greater than that to which the foil is manufactured.

Printer arrangement and method of manufacture

Droplet deposition apparatus comprising an array of fluid chambers defined by a pair of opposing chamber walls, and in fluid communication with a nozzle for droplet ejection therefrom; a cover member is joined to the edges of the chamber walls and thus seals one side of the chambers. The cover member has a ratio of cover thickness to chamber wall separation less than or equal to 1:1.

Droplet deposition apparatus

A droplet deposition apparatus having an array of fluid chambers defined by a pair of opposing chamber walls, and in fluid communication with a nozzle for droplet ejection therefrom; a cover member is joined to the edges of the chamber walls and thus seals one side of the chambers. The cover member has a ratio of cover thickness to chamber wall separation less than or equal to 1:1.

A component for a printhead is created by forming a PZT wafer forming a region of SU8 photoresist material on one side of the PZT wafer; sawing in a second side of said planar body, opposite said first side, actuator channels to a depth sufficient to expose an area of the photoresist material; forming a nozzle through the layer of photo-resist material in the exposed area such that then nozzle is in communication with the actuator channels. The region of photoresist material may be used to form a nozzle plate using photolithography.

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.

Method of manufacture and printer with elastic alignment features

An actuator taking the form of a piezoelectric wall separating two chambers, which utilizes two actuation modes. Both actuation modes cause volume displacements in both chambers, but act to reinforce one another in one chamber and cancel one another in the other chamber. A fluid pump for droplet deposition having an array of channels separated by such actuators can be operated with each channel acting substantially independently of its neighbors.

An ink jet or other printer serves to print for each row of input pixels, two superimposed rows of contiguous 'super pixels,' each print pixel being capable of receiving print contributions from N super pixels. The super pixels are twice the width of the input pixels and one row of super pixels is offset by half a super pixel width from the next row of super pixels. Redundancy is thus provided against the loss of a print element. The effects of smoothing or an image are reduced by edge enhancement processes.

Ink jet printing method and printer

A nozzle in a nozzle plate for an inkjet printhead is formed by directing a laser beam at a nozzle plate. Accurate control of the divergence of the beam is achieved by splitting the beam into sub-beams, each sub-beam having divergence with an origin lying apart from the point at which the beam is created by splitting, and thereafter recombining the sub-beams. Greater accuracy in the taper and inlet shape of the manufactured nozzle is thereby obtained.

Method of and apparatus for forming nozzles

An ink jet printer with ink flowing through an ink chamber and over an ink ejection port leading to a nozzle has a deflection surface such as a chamfer at the junction of the chamber and the ejection port to inhibit debris from entering the port.

A hollow cylindrical support for a plurality of flow-through inkjet print heads has two folded wall sections cooperating to define elongate inlet and outlet ink manifolds, one wall section being thermally conducting so as to promote heat transfer along the length of the support, the other wall section being thermally insulating so as to inhibit heat transfer between the inlet and outlet manifolds. The thermally insulating section serves to trap a boundary layer of fluid, for example in a cavity wall or cellular material.

An ink supply system for a droplet deposition apparatus wherein the pressure at the nozzle is controlled by a remote point, said remote point being positioned in parallel with said print head. The flow restrictions in the printhead arm and the pressure control arm of the circuit being selected to achieve this.

An injet printhead is formed by a multistage process: grooves are formed on the base of a block of piezoelectronic material, and a conductor is applied thereto. Conducting tracks are deposited on a substrate with matching spacing, such that the base and piezoelectric material can be joined giving a desired electrical connection. Channels are cut into the top of the piezoelectric block to intersect with the grooves, forming ink chambers, and these are provided with electrodes in electrical contact with the tracks. Cover plates are added to the assembly to provide a manifold and nozzles.

In a color printhead, print elements for different colors print swaths of pixels in different colors side by side in a first traverse; the printhead and the surface to be printed are indexed, and in the next traverse, further swaths are printed with each new swath overlapping a previous swath in a different color.
