Abstract: A device surface of a substrate is dry-sprayed with a polymeric material (e.g., a photoresist) to provide a spray-coated layer on the surface of the substrate. The spray-coated layer has a thickness ranging from about 0.5 to about 20 microns. Flow features are formed (e.g., imaged and developed) in the spray-coated layer. A nozzle plate layer is applied to the spray-coated layer. The nozzle plate layer has a thickness ranging from about 5 to about 40 microns and contains nozzle holes formed therein to provide the micro-fluid ejection head structure.

Abstract: A method for improving fluidic flow for a microfluidic device having a through hole or slot therein. The method includes the steps of forming one or more openings through at least part of a thickness of a substrate from a first surface to an opposite second surface using a reactive ion etching process whereby an etch stop layer is applied to side wall surfaces in the one or more openings during alternating etching and passivating steps as the openings are etched through at least a portion of the substrate. Substantially all of the etch stop layer coating is removed from the side wall surfaces by treating the side wall surfaces using a method selected from chemical treatment and mechanical treatment, whereby a surface energy of the treated side wall surfaces is increased relative to a surface energy of the side wall surfaces containing the etch stop layer coating.

Abstract: A telescopic sight is provided that includes an integral mounting bar for connection to a barrel of a firearm and integral auxiliary equipment mounting features for mounting auxiliary equipment onto the telescopic sight. The auxiliary equipment mounting features facilitate the mounting of multiple devices that allows for quickly alternating between different aiming devices or to simultaneously use multiple aiming devices. Clamp assemblies cooperate with the mounting bar to secure the telescopic sight to the firearm and provide adjustment of the height position of the telescopic sight. The clamp blocks are adapted to fit onto a mounting rail of a firearm. The mounting features are universal and require no post-mounting adjustment to accurately align the auxiliary equipment.

Abstract: A scoop type patient carrier having separable halves to facilitate placement of the halves beneath a patient, and configured to enable radiographic examination. The joint between the halves, and the points where the pivot and latch mechanisms are located, are laterally offset from the midline or longitudinal centerline of the assembled carrier. This arrangement results in the absence of any joint or line of separation in the upper and lower sections that are aligned with the carrier centerline, and which support the head and feet. This enables the carrier halves to be joined or separated without any accompanying movement of the head and feet of the patient.

Abstract: A multiple position child restraint device for use with vehicles, stretchers, cots, beds, and other transport apparatuses, and which can be folded into planar condition for storage and shipment. The restraint device includes substantially planar back support, seat support, and leg support members hingedly attached in serial relationship with one another generally along a longitudinal axis. The hinged connection between the back support and seat members is preferably provided by a pair of oppositely disposed hinges having a plurality of locking slots which align with one another at predetermined angular relationships, and wherein a locking bar fits within the aligned slots to selectively lock the back support and seat members in one of a plurality of predetermined angular orientations.

Abstract: In a print head for ink jet printing a nozzle plate with a nozzle array is gold plated. The gold plated nozzle array is bonded to the polymer ink barrier layer on an electronic chip by a thin layer of tantalum, zirconium, titanium or silicon dioxide. The thin layer greatly increases the ability of the surface to bond chemically to the polymer.

Abstract: A restraint stretcher comprising an envelope for receiving a rigidifying backboard, and having transverse straps for encircling the body of a patient at specific areas, the straps being mounted for longitudinal movement to fit various sizes of patient. The transverse straps and their anchorage brackets are readily individually removable for cleaning or replacement. The anchorage points can be located on the upper side of the stretcher for immobilizing smaller patients, or on the underside for immobilizing larger or adult patients. The stretcher is padded for patient comfort and includes laterally or outwardly projecting handles for transportation of the stretcher. A harness is provided to constrain the patient against longitudinal movement.

Abstract: There is provided a head immobilizer of the type which can be attached to a rigid backboard support, with the head immobilizer including a base and a pair of laterally extending side support panels. Each of these side support panels further comprises an inner panel and an outer panel, with the inner panel being conformable appropriately to a shape necessary to snugly support a head to be immobilized. The inner panel also includes an opening which effectively divides a portion of that inner panel into a pair of spaced inner support members extending laterally from the base. The outer panel has inner and outer edges, and is hingedly attached adjacent its inner edge to the inner panel such that it is foldable relative the inner panel to provide a substantially rigid brace for securing the inner panel in a desired immobilizing position.

Abstract: The invention comprises a holder for a compressed gas cylinder which allows the cylinder to be secured to the side railing of an emergency stretcher or cot. A curvature lip is positioned over the railing and allows the holder and cylinder assembly to rotate freely when the railing is lowered.
