  • Invariant code optimization in high-level FPGA synthesis
    Patent number: 9547738
    Abstract: A method of programming or configuring an integrated circuit device using a high-level language includes parsing a logic flow to be embodied in the integrated circuit device to identify invariant logic flow, converting the invariant logic flow into separate instruction blocks, incorporating the separate instruction blocks into a high-level language representation of a configuration of resources of the integrated circuit device, and compiling the high-level language representation to configure said integrated circuit device. The high-level language representation can be executed to generate a configuration bitstream for the programmable integrated circuit device, or can be run on a processor on the programmable integrated circuit device to instantiate the configuration.

  • Acoustic enhancement for behind the ear communication devices
    Patent number: 7720243
    Abstract: A device and method for tailoring the audio frequency response of a hearing instrument, such as a hearing aid, by altering the physical characteristics of the device to more accurately compensate for a user's specific hearing loss attributes. The device has a bore formed within its housing which provides a passage for the transmission of sound from the receiver of the hearing instrument toward the user's eardrum. The bore has a custom-designed geometric shape to emphasize desired sound frequencies and therefore produce a predetermined frequency response of sound in combination with any frequency response changes directed by the hearing instrument's circuitry.
