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 system and method for a motorized repeating toy gun. The toy gun includes a base having a first end and a second end upon which elastic rings are stretched and mounted. The toy gun also includes a motor and a spool. The spool has a wrapping portion, is rotatably mounted on the base and is rotatably responsive to the motor. Additionally, the toy gun includes a string. A first portion of the string is positioned around the wrapping portion. A second portion of the string is interwovenly positioned between the second end and each of the elastic rings. The string forcibly wrapped around the spool in response to the operation of the motor, causing the elastic rings to dismount from the second end. Elastic rings, e.g., rubber bands, are loaded onto a base, e.g.
