  • Display system with finger sensing
    Patent number: 11960683
    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%.

  • Method of making poly(arylene ether) compositions
    Patent number: 8906273
    Abstract: A method of making a thermoplastic composition comprises melt extruding a poly(arylene ether) powder to form a first pelletized poly(arylene ether); and melt extruding the first pelletized poly(arylene ether) to form a second pelletized poly(arylene ether), wherein the second pelletized poly(arylene ether) has a level of butyraldehyde less than the first pelletized poly(arylene ether) and the second pelletized poly(arylene ether) has a level of trimethylanisole less than the first pelletized poly(arylene ether).

  • Method of fabricating total dose hard and thermal neutron hard integrated circuits
    Patent number: 8759903
    Abstract: A method of increasing the radiation hardness of a semiconductor device using a modified high density plasma oxide (MHDPDX) film is described. In the method a high density plasma (HDP) process is used to deposit the MHDPDX film. During the HDP process, the silicon source gas to oxygen source gas ratio is chosen so as to deposit an excess silicon content within the MHDPDX film. The MHDPDX film is then annealed to cause the excess silicon to migrate and amalgamate, creating silicon nanoclusters having an average size of about 3-5 nm. The rad-hard properties of conventional BPSG films and various MHDPDX films are then compared.
