David Alves has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240015234
    Abstract: A first event occurs at a first computer at a first time, as measured by a local clock. A second event is initiated at a second computer by sending a message that includes the first time. The second event occurs at a second time, as measured by a local clock. Because of clock error, the first time is later than the second time. Based on the first time being later than the second time, an alternate second time, that is based on the first time, is used as the time of the second event. When a third system determines the order of the two events, the first time is obtained from the first computer, and the alternate second time is obtained from the second computer, and the order of the events is determined based on a comparison of the two times.

  • Publication number: 20220273241
    Abstract: Expandable electrophysiology catheters having electrodes mounted on splines of an expandable member are described. The splines of the expandable member include subsegments between a proximal location and a distal intersection at a central axis. The subsegments can include respective top-down profiles, and at least one of the top-down subsegment profiles is straight between the central axis and an adjacent top-down subsegment profile. The subsegments can be interconnected to extend continuously about the central axis from the proximal location to the distal intersection. Other embodiments are also described.

  • Publication number: 20210259621
    Abstract: The present disclosure provides for monitoring brain health and predicting and detecting seizures via a wearable head ap paratus. An exemplary system includes a wearable head apparatus with a plurality of sensors. The system includes a memory device with instructions for performing a method. The method provides for first receiving electroencephalography (EEG) data and/or other data types output by the plurality of sensors. The EEG data includes electrical signals representing brain activity of a user. The method provides for processing the EEG data and/or other data types using a machine learning model to identify a time window of a subset of the EEG data and/or other data types, which represents a seizure. The method provides for tagging the time window as seizure data. A representation of the time window of the EEG data and/or other data types is then output.

  • Publication number: 20030007616
    Abstract: A method and system for customizing caller ID information can be used in a call center or other telephony system to present customized caller ID information to a called party independent of the telephone line from which the call is made in the call center. The system retrieves at least one call record including a telephone number to be called and a customized caller ID telephone number associated with the call record. The number to be called and customized caller ID number are placed in a setup message formatted using an Integrated Services Digital Network (ISDN) protocol. The setup message is sent to the Public Switched Telephone Network (PSTN) to establish a telephonic connection with the called party. If the called party subscribes to the caller ID service, the customized caller ID telephone number and any associated information will be presented to the called party.
