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 relates, generally, to a child restraint system and, more particularly, to an adjuster and harness for securing a child in a child restraint seat.

A video circuit including a video amplifier adapted to generate an amplified output video signal from an input video signal; a short detection circuit adapted to generate a first signal indicative of whether there is a short present at an output of the video amplifier; and a load detection circuit adapted to generate a second signal indicative of whether there is a load coupled to the output of the video amplifier. The video circuit may further include an input signal detection circuit adapted to generate a third signal indicative of whether an input video signal is present. The third signal generated by the input signal detection circuit may be used to enable the outputting of the first and second signals in order to prevent the false indication of faults at the output of the video amplifier in the absence of an input video signal.

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.

A radio communication apparatus for searching for a base station of a radio communication network is provided. The radio communication apparatus is configured to join a network including a plurality of base stations forming service coverage of radio communication. The radio communication apparatus includes an antenna and a radio circuit coupled to the antenna. The radio circuit is configured to send and receive a radio wave via the antenna to and from one of the base stations. The radio communication apparatus includes a controller coupled to the radio circuit and configured to start and stop an application other than the communication. The controller is configured to search for one of the base stations providing maximum signal strength by way of the antenna and the radio circuit after stopping the application.

The invention discloses an intelligent safety vehicle poncho. The vehicle poncho comprises a poncho body and a warning circuit, the poncho body consists of a clothing cap and a clothing body, the clothing cap and the clothing body are arranged in a removable mode, a retractable waterproof neck band is arranged in the collar part of the poncho or the neck part of the clothing body, a left, a middle and a right sets of sensor devices are arranged on the neck band; the warning circuit is arranged on the poncho, the warning circuit is connected with the three sets of sensor devices separately, the warning circuit comprises a warning light, the warning light indicates the three running states of the vehicle, namely turning left, stopping and turning right. Because the collar part of the poncho or the neck part of the clothing is provided with the retractable waterproof neck band, when a user turns his head, the clothing cap can be turned with the turning of the head, rainwater can be effectively prevented from entering the interior of the poncho, in the meantime the warning device installed on the poncho can make it easy for people or vehicles to recognize the turning and parking of vehicles at rainy days, foggy days and during the nights, the safety of the user 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.
