Abstract: Disclosed is a heart rhythm monitoring apparatus, including a water-proof case, a water-proof patch, at least two electrodes, a battery, and an electric circuit. The water-proof case is attached to the water-proof patch to form a water-proof space for accommodating the battery and the electric circuit. Each electrode is connected to the electric circuit, and outwards extends from the water-proof space to form a sensing end. The electrodes penetrate the water-proof patch and the water-proof patch and the sensing ends contact an animal skin. The water-proof patch provides adhesion, and the sensing ends are configured to sense electrical signal on the animal skin. The electrical signal is processed by the electric circuit, and the corresponding heart rhythm information is acquired and recorded. The present invention provides water-proof feature and possesses a simple structure, thereby improving convenience of use, prolonging operation period, acquiring a long-term record of heart rhythm information.

Abstract: A long-term effective patch structure includes a binding layer, an absorbing layer and a water-proof layer sequentially stacked together. The binding layer has a function of attaching and fixing, and is configured to be attached and fixed on a skin. Sweat or liquid from the skin can pass through the binding layer to reach the absorbing layer, which is aligned with binding layer at the edge. The water-proof layer is water-proof and has vapor permeability, and its area is larger than the area of the absorbing layer. The outer part of the water-proof layer is attachable to the skin. Since the absorbing layer can absorb the liquid from the skin and the water-proof layer can ventilate the vapor to the outside, the skin is kept dry and comfortable and suitable to be attached to human skin for a long period of time without inducing skin allergy or discomfort.

Abstract: In various embodiments, welding washers are utilized to establish electrical connections between electrically conductive wires and electrically conductive pins.

Abstract: A long term physiological signal sensing patch, including a water protective film, an electrode layer, a conductive hydrogel layer, a block layer and a first attaching layer. The water protective film provides functions of electrical insulation, stickiness and water protection. The electrode layer includes at least two electrodes attached to the bottom of the water protective film. The conductive hydrogel layer configured beneath the electrodes is electrically conductive and sticky. The block layer is under the electrodes to block water, and accommodates the conductive hydrogel layer. The first attaching layer is provided around the block layer. Therefore, the sensing patch can be attached to the human body for a long period of time to sense physiological signal, which is further transmitted to the external apparatus for more detailed analysis, calculation or display.

Abstract: A device for long term sensing and recording electrocardiogram includes a housing body, electrodes, a processing circuit, a water-proof film and at least one flexible attach layer. The housing body includes an upper body and a lower body sealed to form an internal space for enclosing the processing circuit. The middle portion of the water-proof film is sandwiched between the upper body and the lower body, and the outer portion of the water-proof film is attached to a person's skin to form a water-proof region. The flexible attach layer is beneath the water-proof film, and the electrodes penetrate the housing body to electrically connect the processing circuit. The electrodes sense electrocardiogram information, which is processed and recorded by the processing circuit. The device is suitable to wear for a long term without any interference such that the user does not feel uncomfortable even during showering, exercising or sleeping.

Abstract: Thin-film batteries are stacked within a structure that permits battery expansion. In various embodiments, the batteries are retained within individual trays that may be tiled into multi-tray layers which are then stacked, or are retained within a stacked series of printed circuit boards or within the pleats of a single, flexible, accordion-folded printed circuit board.

Abstract: An input apparatus for a hand-held electronic device and a computer. The universal input apparatus includes a main connection port, a communication port, an input controller, a communication controller and a route selection unit. The main connection port connects to the hand-held electronic device and the communication port connects to the computer. The input controller provides a plurality of serial input signals. The communication controller, having a serial port coupled to the communication port, is configured to convert the serial input signals into a pair of differential signals transferred through the serial port. Further, the route selection unit establishes a first route between the input controller and the main connection port and establishes a second route between the input controller and the communication controller. Therefore, the serial input signals can be transferred over the first route or the second route alternatively.

Abstract: The invention relates to a wireless keyboard capable of operating with a radiation-based signal receiver of a portable computing apparatus. The wireless keyboard includes a radiation-based signal transmitter functions converting a corresponding key signal into a radiation beam and emitting the radiation beam.
