Apparatuses for use in negative pressure wound therapy are described herein. In some embodiments, the apparatus includes a pump assembly having a pump housing, a magnet, an electrically conductive coil, and a diaphragm, wherein the electrically conductive coil is configured to move a portion of the diaphragm to pump a fluid through the pump apparatus, and a dampener positioned within the pump assembly configured to reduce sound generated by the pump assembly during operation of the pump assembly. In some embodiments, the apparatus includes a housing having a first section and a second section, and an illumination source disposed within the housing adjacent the first section, wherein the illumination source is configured to illuminate the first section, wherein the first section is one of transparent and translucent, and wherein the first section is thinner than the second section as measured perpendicularly from inside to outside the housing. In some embodiments, the pump apparatus includes components configured to be laser welded together.

Systems and methods for controlling a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes applying a drive signal to a pump assembly of the pump system, the drive signal alternating between a positive amplitude and a negative amplitude and the drive signal having an offset, and sampling a pressure within a fluid flow path configured to connect the pump system to a wound dressing configured to be placed over a wound during one or more time intervals. Each of the one or more time intervals can occur when the drive signal is approximately at an amplitude equal to one or more sampling amplitudes.

A method can be used to attach a fabric member to a trim while forming a pattern in the fabric member. A trim has trim grooves formed in one side of the trim and a fabric member has a foam formed in one side of a skin material of the fabric member. A bonding member is coated to an outer surface of the foam and the fabric member is heated where the bonding member is coated. The heated fabric member is placed on the side of the trim where the trim grooves are formed. The fabric member is fixed to the trim by inserting edges of the fabric member into the trim grooves using insertion blades while pattern protrusions formed in a compression jig form a pattern by pressing the skin material of the fabric member.

Systems and methods for controlling a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes causing provision of negative pressure, via a flow path, to a wound dressing configured to be positioned over a wound, the flow path configured to fluidically connect the pump system to the wound dressing, measuring a first pressure value in the flow path at a first time, measuring a second pressure value in the flow path at a second time, calculating a first rate of pressure change using the first and second pressure values, and in response to determining that the calculated first rate of pressure change satisfies a threshold rate of change, providing an indication that the wound dressing is full, wherein the method is performed under control of a controller of the pump system.

A heat-curable tape, a kit, and a method for connecting ends of an elongate belt to form an intermediate transfer members suitable for use with indirect printing systems. The kit includes an elongate belt and the heat-curable tape. The kit can include a crimping pin. The method includes using the heat curable tape to join ends of the elongate belt at a seam. A heater is used, in a printing system, for heat-curing the heat-curable tape onto the free ends of the elongate belt so as to form the intermediate transfer member.

The device includes at least part of an assembly line defining assembly path and assembly plane including the assembly path and plurality of spindles moveable along the assembly path by an apparatus and configured to controlledly pick up the caps, the spindles position and push the caps onto the base supports along the assembly path; positioning apparatus including first and second detectors, controller with auxiliary control system to translate and rotate spindles along directions perpendicular to assembly path and plane and third encoder to detect spindle orientation relative to assembly path. First detector to detect first orientation, second detector to detect second orientation and controller to detect first orientation and second orientation by detectors and operate auxiliary control system to align base support and cap.

A method of making a wind turbine blade is described. The blade comprises first (12) and second (14) half shells bonded together and a shear web (16) bonded inside the shells. Prior to joining the shells together, the shear web is positioned in one of the shells. A plurality of bars (70) are attached to the shear web and engaged with a plurality of mounts (80) in order to support and stabilise the shear web relative to that shell. The shells are then arranged one above the other whilst the bars remain attached to the shear web. The bars continue to support the shear web whilst the shear web is aligned with the other shell. The bars are then detached from the shear web and the shells are brought together to bond the shells to each other and to bond the shear web between the shells.

A method of making a wind turbine blade, and the turbine blade resulting form the process, is described in which correct alignment of the shear webs (42a, 42b) upon mould (30) closing is ensured. The method involves providing a first half shell (32a) and a second half shell (32b) to be joined together to form the wind turbine blade. A first edge (46) of a shear web (42) is attached to an inner surface (36a) of the first half shell (32a). A shear web mounting region is defined on an inner surface (36b) of the second half shell (32b). At least one guide block (60a, 60b) is attached to the inner surface (36b) of the second half shell (32b) adjacent to the shear web (42) mounting region. The guide block (60a, 60b) has a guide surface (70) oriented transversely to the inner surface of the second half shell (36b). Upon mould (30) closing, the first and second half shells (32a, 32b) are brought together whilst a second edge (52) of the shear web (42) is guided over the guide surface (70) of the mounting block (60a, 60b) towards the shear web mounting region defined on the inner surface (36b) of the second half shell (32b).

Systems and methods for controlling and/or calibrating a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes calculating an amplitude and an offset for a drive signal based at least in part on previously calculated parameters and a negative pressure setting, generating the drive signal, and applying the drive signal to a pump system. The pump system can be fludicially connected to a wound dressing positioned over a wound.
