Techniques for detection and treatment of myocardial ischemia are described that monitor both the electrical and dynamic mechanical activity of the heart to detect and verify the occurrence of myocardial ischemia in a more reliable manner. The occurrence of myocardial ischemia can be detected by monitoring changes in an electrical signal such as an ECG or EGM, and changes in dynamic mechanical activity of the heart. Dynamic mechanical activity can be represented, for example, by a heart acceleration signal or pressure signal. The electrical signal can be obtained from a set of implanted or external electrodes. The heart acceleration signal can be obtained from an accelerometer or pressure sensor deployed within or near the heart. The techniques correlate contractility changes detected by an accelerometer or pressure sensor with changes in the ST electrogram segment detected by the electrodes to increase the reliability of ischemia detection.

The invention discloses an intelligent sport suit. The intelligent sport suit comprises a sport suit body, a retractable waterproof neck strap is arranged at the neck portion of the sport suit body, and a left sensing device, a middle sensing device and a right sensing device are arranged on the neck strap. The intelligent sport suit further comprises a warning circuit arranged on the sport suit body, the warning circuit is connected with the three sensing devices separately and comprises warning lights, and the warning lights indicate three possible advancing states of a sportsman, including the state of turning left, the state of stopping and the state of turning right. As the retractable waterproof neck strap is arranged at the neck portion of the sport suit body, when a user turns the head, a cap can turn along with turning of the head; as the warning device is installed on the sport suit body, other people or vehicles can conveniently recognize that the sportsman possibly turns or stops on rainy days or foggy days or at night, the safety of the sportsman is improved, and traffic accidents can be effectively reduced.

The invention belongs to the technical field of protective guards, and particularly relates to a portable fast-built movable protective guard. The protective guard comprises first supporting rods, second supporting rods, hinges, first hinge rods, second hinge rods, third hinge rods, fourth hinge rods and trundles. According to the protective guard, the first supporting rods and the second supporting rods are moved, then the first supporting rods and the second supporting rods rotate around the hinges, the first hinge rods and the second hinge rods are driven to be unfolded and folded, the protective guard is transversely and rapidly unfolded and folded, then the first supporting rod and the second supporting rod on the outermost sides are pulled, the third hinge rods and the fourth hinge rods between the adjacent first supporting rods and the second supporting rods are driven to be unfolded and folded, so that the protective guard is unfolded and folded quickly in the longitudinal direction, the unfolding and folding efficiency of the protective guard is improved, the to-be-isolated positions are separated quickly, and meanwhile, the space required for storage and transportation ofthe protective guard is reduced, so that the protective guard is convenient to store and transport.

The invention relates to a charging circuit for a root canal length measuring instrument and a charging state feedback and display method. The charging circuit comprises a lithium battery charging module, a charging state detection module, a single chip microcomputer, a display screen, a green LED lamp driving module and a yellow LED lamp driving module. The output end of the lithium battery charging module is connected with the input end of the charging state detection module, the output end of the charging state detection module is connected with the charging state detection end of the single chip microcomputer, the data display end of the single chip microcomputer is connected with the display screen, the green LED control signal end of the single chip microcomputer is connected with the green LED lamp driving module, and the yellow LED control signal end of the single chip microcomputer is connected with the yellow LED lamp driving module. The charging state of a battery is detected through the single chip microcomputer, a corresponding pattern is displayed through the display screen to inform a user of the charging state of the battery visually, charging indicator lamps are controlled by an IO interface of the single chip microcomputer, and it is avoided that a green LED and a yellow LED light together to bring about error indications.

An ice fishing trap comprising in its operational state a crossbeam dimensioned for extending across a hole in ice covering a body of water, and a hingedly coupled vertical mast. The vertical mast has a rotatable reel dimensioned to carry a length of fishing line and a hook. A trigger mechanism is provided, wherein a rotation of the reel causes an arcuate movement of a trigger hook. One aspect of the invention provides at least two stabilizer limbs hingedly coupled to the crossbeam, so as to form a general Z shaped support base when operational. In another aspect the fishing trap provides a trigger bolt coupled to an indicator spring, wherein the trigger bolt is utilized to couple the indicator spring to the trigger hook. The trigger bolt is slidingly supported by bolt guide, thus providing improved resistance to false indications due wind vibration and the like. Preferably, the trigger bolt is coupled to the indicator spring by a ring shaped coupler.
