Disclosed is a method for diagnosing myocardial infarction in a subject who suffers from acute coronary syndrome and has a cardiac troponin level, which is detectable, but lower than the level that is considered as being indicative for a myocardial infarction. In one embodiment the present invention includes a method of transmitting information in a wireless communication channel comprising receiving digital signals having data to be transmitted, converting the signals to analog signals, up-converting each analog signal, combining the up-converted signals, amplifying the combined up-converted signal and transmitting the combined up-converted signal. The FBAR is characterized by a resonant frequency having a temperature coefficient, and comprises opposed planar electrodes and a piezoelectric element between the electrodes. The wire cover is slidably engaged with the groove of the junction box main body. Upon receipt of the wireless signal, the remote receiver triggers an alert notification notifying the user that data processing system has received the specified event. An inner surface of each cell wall is provided with an electrode for applying an electric field across at least some of the liquid crystal material.
