Abstract:
A method for aiming a projectile weapon may utilize an aiming device having a primary aiming mark adapted to be sighted-in at a first selected range and one or more secondary aiming marks spaced below the primary aiming mark, and includes identifying, from at least two different groups of projectiles, a projectile group corresponding to a selected projectile. An aiming adjustment for the projectile weapon is determined and effected based on the range to the target and the nominal ballistic characteristics of the identified projectile group corresponding to the selected projectile. Other methods of aiming include identifying one projectile group from two or more predetermined projectile groups based on a selected projectile. Each predetermined projectile group preferably includes two or more different projectiles, preferably of different calibers, and a projectile having ballistic characteristics that are approximately median for each such projectile group.
Abstract:
Systems and methods of printing to a tangible medium provide for reducing ink penetration via the controlled selection of halftone patterns. One method includes steps of printing to the tangible medium (e.g., via a multicolor ink supply such as CMYK) using a plurality of initial halftone patterns, measuring ink absorption of the tangible medium in response to printing to the tangible medium, and determining a subset of the plurality of initial halftone patterns based on the absorption measurement. The method also includes printing a print job to the tangible medium based on the subset of the plurality of initial halftone patterns. For example, a print controller may be reprogrammed with the subset of the plurality of initial halftone patterns to print a print job to reduce the amount of ink applied to the tangible medium.
Abstract:
A laryngoscope blade in accordance with one embodiment includes a blade portion including a tab extension, the tab extension including a tab extension slot for receiving a portion of a laryngoscope handle; and a heel coupled to the tab extension by means of a fastener, the heel including a heel slot that aligns with the tab extension slot and also receives the portion of the laryngoscope handle, wherein the heel is colored to indicate a size of the blade portion of the laryngoscope blade.
Abstract:
A method of making a micro-fluid ejection head structure and structures made by the method. The method includes planarizing a heated substrate component of a micro-fluid ejection head structure by applying a clamping voltage to an electrostatic chuck sufficient to hold the substrate component in a planarized orientation. A polymeric nozzle layer is laminated to the heated substrate component in a manner sufficient to provide a planarized nozzle layer on the substrate component.
Abstract:
An improved photoimaged nozzle plate for a micro-fluid ejection head, a micro-fluid ejection head containing the nozzle plate, and methods for making a micro-fluid ejection head. The improved nozzle plate is provided by a photoresist nozzle plate layer applied to a thick film layer on a semiconductor substrate containing fluid ejector actuators. The photoresist nozzle plate layer has a plurality of nozzle holes therein. Each of the nozzle holes are formed in the nozzle plate layer from an exit surface of the nozzle plate layer to an entrance surface of the nozzle plate layer. Each of the nozzle holes has a reentrant hole profile with a wall angle greater than about 4° up to about 30° measured from an axis orthogonal to a plane defined by the exit surface of the nozzle plate layer.
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 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. A multiple strap restraint device including a pair of shoulder straps and a releasable buckle secures the child on the seat and back support members, and an arrangement is provided for convenient adjustment of the shoulder straps along the longitudinal length of the back support member to accommodate children of different sizes without disconnecting the straps from the device. Folding lateral support panels are also provided along the opposite longitudinal edges of the seat and back support members.
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.
