Laser scanning assembly having an improved scan angle-multiplication factor
InactiveUS8408469B2Increase multipleUniform collectionMirrorsBeam/ray focussing/reflecting arrangementsRotational axisAcute angle
A laser scanning system for generating a laser scanning pattern in a scanning field, while amplifying the scan-angle multiplication factor of rotating mirrors employed therein. The laser scanning system employs rotatable laser scanning assembly having an axis of rotation and first and second rotating mirrors with normal vectors that are coplanar with each other and said rotational axis, and which form an acute angle substantially less than 90 degrees so as to provide a laser scanning assembly with a scan angle multiplication factor that is greater than 2.0. A cluster of stationary mirrors mounted about the first and second rotating mirrors, for sweeping a laser beam off the cluster of stationary mirrors after a laser beam has been reflected off the first rotating mirror, then reflected off the second rotating mirror, and then directed outwardly towards an array of pattern mirrors, so as to generate a resultant laser scanning pattern within the scanning field.

Transcutaneous inserter for low-profile infusion sets
A low-profile inserter for an angled infusion set comprises an inserter housing having a bottom wall, a retainer slidably connected to the inserter housing for movement between retracted and extended positions in a direction substantially parallel with the bottom wall, and a base member connected to the inserter housing. The retainer is adapted to releasably receive a cannula assembly, including a cannula connected to a cannula housing. The base member has a lower surface that is adapted to contact a skin outer surface. The lower surface and bottom wall together form an acute angle. With this arrangement, the cannula can be inserted subcutaneously at the acute angle with respect to the skin outer surface.

Nasal cannula assembly
A nasal cannula assembly designed for contact with the nasalabidial area of a patient's face comprising a nasal cannula, a pair of oxygen supply tubes connected to opposite ends of the nasal cannula and a main oxygen supply line. The nasal cannula is made of a flexible plastic material molded into a light-weight hollow tubular member having a main body portion formed at an acute angle in the center and having a pair of spaced exterior orifices projecting from the body at an angle and curved upwardly and inwardly for directing gas flow into a patient's nostrils. Attachment points for oxygen supply tubes are above center of gravity of the nasal cannula to make it self-righting thus eliminating need for stiff supply tubing to orient cannula. Oxygen supply tubes made from ultra-high molecular weight PVC possess superior flexibility and low compression set so that little tension on the tubing is required to hold cannula in proper position. A main oxygen supply line made from ultra-high molecular weight PVC resists the formation of twisted loops that tend to block oxygen flow.

The invention provides a main conduit connected to an atomizing nozzle mounted in a wall of the reactor and first and second conduits for flowing bitumen and steam respectively into the main conduit. The first conduit is angled relative to the main conduit at an acute angle of about 45° and the second conduit is angled relative to the main conduit at an acute angle of about 30°. The second conduit is positioned upstream of the first conduit by a short distance of about 23 mm and may be angled radially relative to the first conduit by any angle, although a 90° angle is preferred. A flow accelerating nozzle is located in the second conduit adjacent the entrance therefrom into the main conduit The arrangement of the invention improves the flow characteristics of 2-phase material flowing to the atomizing nozzle, reducing pulsations in the main conduit and improving the resulting atomization of the bitumen in the reactor.

Head-up display with polarized light source and wide-angle p-polarization reflective polarizer
A head-up display includes a projection system and a window having a target area where a reflective polarizer is positioned to reflect light from the projection system to a viewing area. Light from the projection system is p-polarized and strikes exposed window surface(s) at an acute angle to reduce or eliminate multiple or “ghost” images. The acute angle is closely matched to a Brewster angle of the exposed window surface(s). The reflective polarizer includes a multilayer stack with refractive indices of individual layers chosen to reflect p-polarized light substantially more than s-polarized light over a wide angular range that includes the acute angle. The reflective polarizer also can reflect infrared light to reduce cabin heating from solar radiation.
