  • Publication number: 20180359550
    Abstract: The invention is a multi-microphone voice processing SoC primarily for head worn applications. It bypasses the use of conventional pre-amp voice CODEC (ADC/DAC) chips all together by replacing their functionality with digital MEMS microphone(s) and digital speaker driver (DSD). Functionality necessary for speech recognition such as noise/echo cancellation, speech compression, speech feature extraction and lossless speech transmission are also integrated into the SoC. One embodiment is a noise cancellation chip for wired, battery powered headsets and earphones, as smart-phone accessory. Another embodiment is as a wireless Bluetooth noise cancellation companion chip. The invention can be used in headwear, eyewear glass, mobile wearable computing, heavy duty military, aviation and industrial headsets and other speech recognition applications in noisy environments.

  • Patent number: 7242383
    Abstract: An active matrix color crystal display has an active matrix circuit, a counterelectrode panel and an interposed layer of liquid crystal. The active matrix display is located in a portable microdisplay system that has a display computer that generates images to be displayed on the liquid crystal display and connected to the active matrix liquid crystal display. A data link transmits data at a rate of speed of greater than 200 Mbytes per second in series for at least a portion between the display computer and the active matrix liquid crystal display. In a preferred embodiment, the display system has a randomizing device that alternates the amplifier through which an analog video signal passes.

  • Patent number: 7122841
    Abstract: A semiconductor device includes a substrate having a first major surface; a semiconductor device structure over the first surface of the substrate, the device structure comprising an n-type semiconductor layer, and a p-type semiconductor layer over the n-type semiconductor layer; a p-side electrode having a first and a second surface, wherein the first surface is in electrical contact with the p-type semiconductor layer; and a p-side bonding pad over the p-side electrode. Preferably, the semiconductor device further comprises an n-side bonding pad over an n-type semiconductor layer. The p-side and n-side bonding pads each independently includes a gold layer as its top layer and a single or multiple layers of a diffusion barrier under the top gold layer. Optionally, one or more metal layers are further included under the diffusion barrier. Typically, the p-side bonding pad is formed on the p-side electrode.

  • Patent number: 7002180
    Abstract: A bonding pad for an electrode is in contact with p-type gallium nitride-based semiconductor material that includes aluminum. The bonding pad may also includes one or more metals selected from the group consisting of palladium, platinum, nickel and gold. The bonding pad can be used to attach a bonding wire to the p-electrode in a semiconductor device, such as a light-emitting diode or a laser diode without causing degradation of the light-transmission and ohmic properties of the electrode. The bonding pad may be formed of substantially the same material as an electrode in making an ohmic contact with n-type gallium nitride-based semiconductor material (n-electrode). This allows the bonding pad and the n-electrode to be formed simultaneously when manufacturing a gallium nitride-based light-emitting device which substantially reduces the cost to manufacture the device.
