  • PROSTHETIC VALVE WITH EXPANDABLE FRAME AND ASSOCIATED SYSTEMS AND METHODS
    Publication number: 20240081987
    Abstract: Aspects of the disclosure relate to prosthetic valves having a frame, a frame cover, and a leaflet construct. Some aspects are directed to a diametric taper for the prosthetic valve for achieving enhanced performance of the prosthetic valve under operational conditions, enhanced compressibility and delivery characteristics, and other additional or alternative advantages. Other aspects are directed toward unique assembly and attachment methods for securing leaflet constructs to support structures. Other aspects are directed toward features for interacting with transcatheter delivery systems. Still other aspects are directed to such apparatuses, systems, and methods for valve replacement, such as cardiac valve replacement.

  • Audio amplifier in compact case with peak voltage and current limiting circuit and thermal cooling tunnel
    Patent number: 8130495
    Abstract: An audio sound system has a printed circuit board disposed within a compact case. The PCB has a power conversion circuit for generating an operating potential, audio amplifier circuit coupled for receiving the operating potential to amplify an audio signal, and peak voltage and current limiting circuit coupled to the audio amplifier circuit to avoid hard clipping of the audio signal. The power conversion circuit has heat-generating components. A cooling tunnel is mounted over the printed circuit board. A cooling fan is mounted in the compact case adjacent a first opening of the cooling tunnel for directing air flow through a second opening of the cooling tunnel over the PCB. The cooling tunnel has a notch formed in a side of the cooling tunnel for directing air flow over the PCB. The audio amplifier circuit can generate greater than 500 watts into a 4-ohm load.
