摘要： Apparatus, including an enclosure having a base and a cover with respective conductive layers. The conductive layers connect to form a shield attenuating electromagnetic radiation originating outside the enclosure in a range of 10 kHz-100 kHz by at least 20 dB within the enclosure. An adapter circuit within the enclosure processes electrophysiological signals to generate an output signal. A first connector passing through the enclosure connects to a probe to receive the electrophysiological signals and convey them to the adapter circuit. A second connector passing through the enclosure receives the output signal from the adapter circuit and conveys it to a console. A control input receives a control signal indicative of a frequency within the range, and a sensing circuit senses a magnetic field within the enclosure and outputs a warning signal when the magnetic field at the frequency indicated by the control signal exceeds a preset threshold.

摘要： A human body sensing mat can sense the movement of a human body and analyze a user's sleep. The human body sensing mat may include a substrate; a plurality of fiber sensors for generating signals according to a distance to a specific object; a sensor array disposed on the substrate; a shield layer for covering the sensor array; and a driving unit for applying a voltage to the sensor array. Each of the fiber sensors is disposed on a central portion of the substrate and on both ends of the substrate. The fiber sensors that are respectively disposed in the central portion and end portions of the mat can sense the user's breathing, tossing and turning, and the like regardless of the user's posture. Accordingly, the user's sleep can be analyzed regardless of the user's posture.

摘要： A vascular assessment device includes an antenna unit and a fabric unit. The antenna unit includes a substrate, a transmitting antenna and a receiving antenna spaced apart disposed on the substrate, and a circuit module disposed on the substrate. The circuit module cooperates with the transmitting antenna to emit a carrier radio wave toward a fistula of a subject, and receives, via the receiving antenna, a return wave signal formed through reflection of the carrier radio wave. The fabric unit is sleeved on the antenna unit, and includes an isolating layer adapted to be disposed between the transmitting antenna and the skin above the fistula. The fabric unit has a dielectric constant not greater than 3.

摘要： Example embodiments include devices and systems that detect apnea events of a user. The device includes a first sensor configured beside the head of the user for capturing snoring sounds of the user, a second sensor configured on one finger of the user for capturing cardiovascular parameters of the user, a third sensor configured under the trunk of the user for capturing e breathing movements of the user, a data recorder that is connected with the first sensor, the second sensor and the third sensor for receiving recordings therefrom, and a clock for synchronizing the recordings in real time. The recordings include one or more breathing events including snoring events, heart rate and SPO2 conjunction spikes, and breathing movement cessations. The time periods that apnea events are impossible can be excluded according to a combination of the breathing events, and the apnea events can be detected thereafter.
