  • Patent number: 10682124
    Abstract: A method for collecting and analyzing urine at the time it is released uses a urine collecting tube joined with a canister. Suction is produced in the collecting tube to join the tube with a penis or to the exterior surface of a female urethra orifice. Once suction is achieved the collecting tube stays in place by suction action. When urine flows into the urine collecting tube a sensor triggers a vacuum pump to produce a higher level of suction to flush the urine into the canister where a level sensor determines the quantity of urine received. Various sensors in the canister determine levels of non-urine partials such as occult blood, drugs, salt, and other substances. When urine is no longer detected within the urine tube, the vacuum pump is turned off and a low-level vacuum remains to assure interconnection with the urine tube.

  • Patent number: 8994536
    Abstract: The present invention provides a new non-invasive technique for organ, e.g., heart and lung, monitoring. In at least one embodiment of the invention, a subject is radiated with a non-harmful and relatively low power electromagnetic source diagnostic signal normally associated with a communications protocol such as, but not limited to a version of the IEEE 802.11(x) family of protocols in the 2.4, 3.6, or 5 GHz spectrum bands. After passing through the patient, a return signal is acquired from the patient and compared to the original source signal. The differences between the source and modified signals are then analyzed to monitor the heart, e.g., measure heart rate and detect defects within the heart, and the lung. For example, using Doppler Effect principles, heart rate and motion can be measured from the differences in frequency, phase, and/or wavelength between the source signal and the modified signal reflected back from the heart moving within the patient.

  • Patent number: 8972228
    Abstract: Techniques for evaluating cardiac electrical dyssynchrony are described. In some examples, an activation time is determined for each of a plurality of torso-surface potential signals. The dispersion or sequence of these activation times may be analyzed or presented to provide variety of indications of the electrical dyssynchrony of the heart of the patient. In some examples, the locations of the electrodes of the set of electrodes, and thus the locations at which the torso-surface potential signals were sensed, may be projected on the surface of a model torso that includes a model heart. The inverse problem of electrocardiography may be solved to determine electrical activation times for regions of the model heart based on the torso-surface potential signals sensed from the patient.

  • Publication number: 20150005653
    Abstract: A personal electronic device is configured to unobtrusively detect heart rate and rhythm anomalies utilizing an electrocardiogram (EKG)-based detection and monitoring method. As one example, while a user is using the personal electronic device for its intended function, such as communicating, playing music, and/or watching videos, the personal electronic device may be unobtrusively detecting and recording a user's heart rate and heart rhythm to detect anomalies. For instance, while a user is making a phone call, electrodes of the personal electronic device located in the vicinity of the earpiece and on the handset, may come into contact with a user's ear and a user's hand respectively. Thus, while the personal electronic device is being consciously used for a function other than EKG monitoring, EKG monitoring is unobtrusively occurring.

    Abstract: An arousal-level determining apparatus includes a generating unit, a calculating unit, an identifying unit, and a determining unit. The generating unit generates heartbeat-interval variation data, which indicates changes in heartbeat interval, on the basis of heartbeat signals indicating subject's heartbeats. The calculating unit applies a band-pass filter, which allows passage of a certain range of frequencies, to each frequency band in the heartbeat-interval variation data while changing the frequency band, and calculates spectral density with respect to each frequency band applied with the band-pass filter. The identifying unit identifies a feature point corresponding to a spectral density peak in the calculated spectral densities in the frequency bands. The determining unit determines subject's arousal level on the basis of the identified feature point.

  • Publication number: 20140357960
    Abstract: A method and device is described, which measures and records one or more repetitive biological signals, such as heartbeat, breathing rate, and/or intrinsic brainwave frequency, and uses these tempos and timing information as a feedback mechanism to an individual doing one or more repetitive motion activities, in order to synchronize the activities with the repetitive biological signals, or a simple ratio of harmonics or sub-harmonics thereof. The feedback is achieved through a visual, audio, or tactile signal that indicates to the individual pacing information for precisely when to perform the activity. The purpose of synchronizing repetitive motion activity to biological activity is to optimize the efficiency of the system as a whole, reducing energy consumption and promoting calm and focused performance. Repetitive motion activities include but are not limited to breathing, running, bicycling, swimming, walking, hiking, jump rope, and rowing.

  • Patent number: 8855755
    Abstract: Techniques are described for distinguishing between treatable and non-treatable heart rhythms. A medical device that operates in accordance with the techniques analyzes characteristics over several cardiac event intervals to detect initiation of a sudden rate onset. After detection of the initiation of the sudden rate onset, the IMD analyzes a morphology of an EGM associated with a selected cardiac event within the first several beats after the initiation of sudden rate onset. In one example, the IMD analyzes the morphology of the EGM associated with the first cardiac event immediately subsequent to the initiation of the sudden rate onset. If the morphology of the EGM of the selected cardiac event is abnormal compared to template EGM, the rhythm is classified as treatable. Otherwise, the rhythm is classified as non-treatable.
