  • Deep learning algorithms for heartbeats detection
    Patent number: 10709390
    Abstract: A system that detects heartbeats includes a sensor or a transducer and algorithms based on deep learning. The algorithms employ techniques of artificial intelligence that enable the system to extract heartbeat features under low signal-to-noise-ratio (SNR) conditions when a user is exercising. The algorithms can be applied to various technologies for heart rate monitoring such as ultrasound Doppler, photoplethysmogram (PPG), electrocardiogram (EKG), acoustic, pressure/force sensing and laser/RF Doppler, among other types of sensing methods.

  • High capacity, low jam envelope feeder for laser printer
    Patent number: 5520381
    Abstract: An envelope feeder using a combination of frictional force differentiation and three discrimination edges, two of which are provided by flexible materials spaced apart from and on either side of a metal envelope separating plate to prevent multiple envelope feeds into printers. The flexible plate on the media side of the metal envelope separating plate is at a more acute angle to the vertical than the metal envelope separating plate, and the metal envelope separating plate of the invention is at a more acute angle than the angles used by metal envelope separating plates in the prior art. A third discrimination edge is provided by a flexible plate which is behind the metal envelope separating plate and which has an angled portion which is longer than the angled portion of the metal envelope separating plate so as to extend past the end of the angled portion of the metal envelope separating plate by about 0.15 inches.

  • Intraocular surgical scissors
    Patent number: 5275607
    Abstract: An intraocular scissors including a handpiece which supports a detachable assembly having a pair of elongated relatively reciprocable blade members suitable for intraocular surgery. One of the blade members is fixedly mounted with respect to the handpiece and the other is mounted for reciprocating movement. Drive means are provided to operate the scissors in various modes including different rates of movement of the reciprocating blade member.
