Abstract:
An integrated bioinformatics sensing apparatus includes a piezoelectric sensing layer, an upper conductive layer, a bottom conductive layer and an information transmission controller. The piezoelectric sensing layer senses a physiological rhythm of a living organism to output a physiological rhythm signal, and the upper and bottom conductive layers sense a physiological electrical signal on a body surface of the living organism, and the information transmission controller receives and processes the physiological rhythm signal and the physiological electrical signal to generate and store the sensed bioinformatics, or transmit the signals to the external processing device to display the sensed bioinformatics. The simple-structured sensing apparatus can be attached onto the body surface of the living organism conveniently.
Abstract:
Described here are devices and methods for treating one or more conditions or symptoms associated with a tonsil procedure. In some variations, a drug-releasing device may be at least partially delivered to one or more tonsillar tissues before, during, or after a tonsil procedure. In some variations, the drug-releasing device may be configured to be biodegradable. In other variations, the drug-releasing device may comprise one or more hemostatic materials or one or more adhesives. The drug-releasing device may be configured to release one or more drugs or agents, such as, for example, one or more analgesics, local anesthetics, vasoconstrictors, antibiotics, combinations thereof and the like.
Abstract:
An active slave device for a Bluetooth system comprises a non-volatile memory unit for storing a plurality of link keys corresponding to a master device capable of switching among a plurality of operating modes, wherein the plurality of link keys correspond to the plurality of operating modes and are generated by a key pairing performed between the active slave device and the master device; and a key fishing unit for searching whether any of the plurality of link keys conforms to a qualified link key that can enable the active slave device under the current operating mode of the master device.
Abstract:
A fracturing apparatus is provided. The fracturing apparatus includes a first board portion, a pressing element, a first suction device, a second board portion, a second suction device, and a cylinder. The first suction device is secured to the first board portion. The second board portion is rotatably connected to the first board portion. The second suction device is secured to the second board portion. The pressing element is secured to the first board portion and disposed between the first board portion and the second board portion. The cylinder is located on the first board portion and includes a piston rod rotatably connected to the second board portion. When the piston rod extends, the second board portion is pressed by the piston rod and swiveled about the first board portion.
