A system including an EMI shield. In an embodiment, the system includes a chassis with at least one bay for receiving a replaceable unit and a lip. The replaceable unit includes a housing and a faceplate. Further, a gasket is operationally coupled to the replaceable unit housing and the replaceable unit faceplate for reducing electromagnetic radiation emissions from the replaceable unit and chassis interface. The gasket may include four sides which are configured to provide a varying force-compression curve along the length of the gasket. Upon installation of the replaceable unit, the lip defined within the chassis compresses the gasket to provide a constant force per unit length and form an electromagnetic interference shield with uninterrupted electrical conductivity.

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.

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.

The present invention is directed to an apparatus for reducing and constraining EMI (electronic magnetic radiation) emissions without affecting the internals of data storage system components. A baffle is attached to the exterior of the housing of a data storage system component by baffle mounts. The baffle is operable between a closed position, where the baffle blocks EMI emitted by connectors on the data storage system component, and an open position, where the connectors are not blocked allowing for servicing and cable management. The baffle may comprise an EMI absorbing material and be tuned to meet specific EMI requirements. The baffle mounts offsets the baffle from the data storage system component and the baffle includes a number of holes to allow airflow. The adjustable EMI baffling apparatus does not interfere with other mounted components while the data storage system component is mounted in a cabinet.

An electromagnetic interference (EMI) gasket for an electronic module comprises a valley feature formed on one side of an EMI gasket and a crown feature formed on the other side of the EMI gasket in order to complement the valley. One or more EMI gaskets are used to construct a shield across the opening of a module cage or rack. Each gasket forms a link in a series of modules, in order to complete a seal across the opening in the cage. A perpendicular pressure forces the module gaskets to center and align evenly as the crown and valley of the opposite features nest together. The modules can be then pressed together and the overlap of the crown and valley acts to center the alignment and create a pressure for satisfactory EMI grounding and the reduction of EMI leakage.

Prior to cooling, an air knife is used to remove bubbles from confectionery-filled chocolates, preferably center-filled chocolates, deposited in a mold tray, preferably using a one-shot depositor. Using the method and apparatus, it is possible to manufacture novel confectionery products, including one-shot deposited caramel-filled dark chocolates.

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.
