  • Patent number: 12233241
    Abstract: Methods and systems to validated physiologic waveform reliability and uses thereof are provided. A number of embodiments describe methods to validate waveform reliability, including blood pressure waveforms, electrocardiographic waveforms, and/or any other physiological measurement producing a continuous waveform. Certain embodiments output reliability measurements to closed loop systems that can control infusion rates of cardioactive drugs or other fluids in order to regulate blood pressure, cardiac rate, cardiac contractility, and/or vasomotor tone. Further embodiments allow for waveform evaluators to validate waveform reliability based on at least one waveform feature using data collected from clinical monitors using machine learning algorithms.

  • Patent number: 11055953
    Abstract: Disclosed are embodiments of a video display input assembly including a mechanical rotatable bezel surrounding the video display. The video display input assembly is suitable for use in a gaming terminal, a gaming cabinet or a gaming machine, including as a retrofit to an pre-existing gaming machine. Direction and speed of a manual rotation of the bezel is detected and interpreted. The result may be used to control various aspects of operation of the gaming terminal, gaming cabinet or gaming machine, including providing input for game play. The video display may be updated in real-time to reflect the rotation of the bezel. A motor may be coupled to the rotatable bezel to provide resistance, assistance or operator feedback.

  • Publication number: 20170193604
    Abstract: Embodiments of the invention provide for systems, computer program products, and methods for a financial wellness application that provides an overview of the financial well-being of users. The financial wellness of the users may be determined by identifying personal characteristics of the users regarding background information about the users and the users' households. Based on a user's personal characteristics, financial wellness questions are determined from a plurality of financial wellness questions to present to the user for which the user provides financial wellness input. The financial wellness input is transformed into a financial situation assessment, day-to-day management assessment, and preparation for the future assessment, which are transformed into an overall wellness score. Moreover, the financial wellness input may also be compared against financial wellness thresholds.

  • Patent number: 9637999
    Abstract: An isolation method is described for gravel packed zones separated by at least one packer and having an auxiliary conduit passing through the packer into adjacent zones. The conduit includes at least one each of a shunt tube, flow housing, annular space, and isolation valve housing. The flow housing, the annular space, and the isolation valve housing are all annular and formed between two concentric pipes. The method includes running in an assembly of screens isolated by at least one packer with at least one auxiliary conduit extending into adjacent zones defined by the packer when the packer is subsequently set. The method also includes closing flow in said conduit to prevent flow into shunt tubes during production based on creating a flow barrier in the annular space, the flow housing, or the isolation valve housing, the shunt tubes supplying slurry through the auxiliary conduit prior to the production.

  • Patent number: 9577395
    Abstract: A universal socket device comprises a plurality of sockets arranged in one interface panel, and transformer circuits disposed inside a body. The interface panel is arranged on top of the body, while a male connector is arranged on the lower side of the body adapted to connect to the output power. The male connector includes a plug with 8-shaped cross sections, arranged along the outside wall of the body in parallel. The base of the plug is disposed on a bulge protruding from the body, and a plane is arranged on the outer surface of the bulge, where a groove extends following the same direction of the plug. Due to the male connector structure disposed on the lower side of the body, the center of gravity of the socket device is stabilized, and the socket device is easy to plug and use.

  • Patent number: 9190760
    Abstract: A plug structure for connecting sockets comprises at least one jack formed at a side of a first socket; and a plug rod disposed on a second socket corresponding to the at least one jack and configured to plug in the at least one jack. The plug rod is electrically contacted with a spring piece in the jack so as to electrify the second socket. A slidable baffle plate is disposed on an inner side of the at least one jack and is configured to cover the jack. A through hole corresponding to the jack is formed in the baffle plate. A slope configured to push the baffle plate is disposed at a position on the baffle plate corresponding to the jack, and is disposed at an edge of the through hole and fitted with the plug rod to push the baffle plate to be inserted into the through hole. The plug structure for connecting sockets according to the present disclosure provides an improvement for a security protection of combined interfaces of the sockets, thus ensuring a security of the combined sockets.
