  • Patent number: 8842845
    Abstract: The invention relates to a method for adapting sound pressure levels in at least one listening location, the sound pressure being generated by a first and a second loudspeaker, each loudspeaker having a supply channel arranged upstream thereto, where at least the supply channel of the second loudspeaker modifies the phase of an audio signal transmitted therethrough according to a phase function. The method includes supplying an audio signal to the supply channels and thus generating an acoustic sound signal; measuring the acoustic sound signal at each listening location and providing corresponding electrical signals representing the measured acoustic sound signal; estimating updated transfer characteristics for each pair of loudspeaker and listening location; calculating an optimum offset phase function based on a mathematical model using the estimated transfer characteristics; updating the phase function by superposing the optimal offset phase function thereto.

  • Patent number: 8835271
    Abstract: It is an object of the present invention to provide a semiconductor display device having an interlayer insulating film which can obtain planarity of a surface while controlling film formation time, can control treatment time of heating treatment with an object of removing moisture, and can prevent moisture in the interlayer insulating film from being discharged to a film or an electrode adjacent to the interlayer insulating film. An inorganic insulating film containing nitrogen, which is less likely to transmit moisture compared with an organic resin, is formed so as to cover a TFT. Next, an organic resin film containing photosensitive acrylic resin is applied to the organic insulting film, and the organic resin film is partially exposed to light to be opened. Thereafter, an inorganic insulting film containing nitrogen, which is less likely to transmit moisture compared with an organic resin, is formed so as to cover the opened organic resin film.

  • Patent number: 8823049
    Abstract: A light-emitting diode (LED) device is provided. The LED device has a lower LED layer and an upper LED layer with a light-emitting layer interposed therebetween. A current blocking layer is formed in the upper LED layer such that current passing between an electrode contacting the upper LED layer flows around the current blocking layer. When the current blocking layer is positioned between the electrode and the light-emitting layer, the light emitted by the light-emitting layer is not blocked by the electrode and the light efficiency is increased. The current blocking layer may be formed by converting a portion of the upper LED layer into a resistive region. In an embodiment, ions such as magnesium, carbon, or silicon are implanted into the upper LED layer to form the current blocking layer.

  • Patent number: 8809836
    Abstract: Techniques are disclosed for providing a low resistance self-aligned contacts to devices formed in a semiconductor heterostructure. The techniques can be used, for example, for forming contacts to the gate, source and drain regions of a quantum well transistor fabricated in III-V and SiGe/Ge material systems. Unlike conventional contact process flows which result in a relatively large space between the source/drain contacts to gate, the resulting source and drain contacts provided by the techniques described herein are self-aligned, in that each contact is aligned to the gate electrode and isolated therefrom via spacer material.

  • Patent number: 8803152
    Abstract: In the case where a material containing an alkaline-earth metal in a cathode, is used, there is a fear of the diffusion of an impurity ion (such as alkaline-earth metal ion) from the EL element to the TFT being generated and causing the variation of characteristics of the TFT. Therefore, as the insulating film provided between TFT and EL element, a film containing a material for not only blocking the diffusion of an impurity ion such as an alkaline-earth metal ion but also aggressively absorbing an impurity ion such as an alkaline-earth metal ion is used.
