Abstract: A display system for sensing a finger of a user applied to the display system includes a display panel; a sensor for sensing the finger; a sensing light source configured to emit a first light having a first wavelength W1; and a reflective polarizer disposed between the display panel and the sensor. For a substantially normally incident light, an optical transmittance of the reflective polarizer versus wavelength for a first polarization state has a band edge such that for a first wavelength range extending from a smaller wavelength L1 to a greater wavelength L2 and including W1, where 30 nm?L2?L1?50 nm and L1 is greater than and within about 20 nm of a wavelength L3 corresponding to an optical transmittance of about 50% along the band edge, the optical transmittance has an average of greater than about 75%.

Abstract: A recreational watercraft having a housing and a structure disposed within the housing for supporting a person. The housing is adapted to be moved through the water by being towed or in other ways. Foot operated rudders are provided on the forward part of the housing and on the rearward part of the housing and are linked together whereby movement of the forward rudder in one direction causes movement of the rear rudder in an equal and opposite direction for causing rapid movement from side to side of the watercraft. Additionally, hand operated rudders are provided for causing turning of the housing about a longitudinal axes.

Abstract: A high pressure laminate (HPL) is disclosed for use on an access floor panel. The HPL is comprised of a rigid, moisture, impervious melamine plastic layer laminated under high pressure and heat to a substrate layer comprised of a resin paper element of multiple sheets of phenolic resin impregnated kraft paper. This resin paper element has at least one groove in it, wherein material has been removed to a depth sufficient to sever enough paper sheet grain lines of the resin paper element so that, after the HPL has been adhesively bonded to the HPL receiving surface of an access floor panel, vertical expansion or contraction of the resin paper element will note elongate the bond line in the area from the edge of the HPL to the groove that creates the pivot or hinge line. An access floor panel is also disclosed.
