Abstract: This invention relates to dynamically controlled, electronic article surveillance (EAS) systems whereby an array of antenna elements is digitally phased and actively driven for concurrent transmission, and digitally phased and combined in the receiver unit to improve detection. In particular, the individual frequency and phase of the plurality of the transmit/receive signals are rapidly varied to allow for automated manipulation (steering) of the transmit field pattern and receive field sensitivity. The invention achieves the following features via means of digital phasing and dynamic computer control: sufficient far-field cancellation, null-free detection and uncompromised detection performance regardless of tag's orientation while using single transmission drivers to drive entire antenna structures, whether loop antenna or ferrite core antenna, using a phase coupler, thereby allowing more efficient system operation or additional features such as deactivator antenna operation.

Abstract: An antitheft security system and method using networked pedestals for monitoring, and reporting data relating to, merchandise, having security tags coupled to or embedded therein, leaving or entering a business establishment and alerting business establishment personnel when a theft may be occurring. The system and method collect and communicate security tag data and associated peripheral device data to a remote server for analysis.

Abstract: A method and apparatus for non-invasive, real-time monitoring of the autonomic nervous systems using non-stationary spectral analysis of both heart rate and respiratory signals. Continuous wavelet transformation is used in real-time so that the dynamic interactions between the sympathetic and parasympathetic divisions of the autonomic nervous system can be independently monitored in the frequency domain. The method in accordance with the present invention allows spectral analysis, formerly limited to the study of stationary data, to be applied to time-varying biological data such as heart rate variability and respiratory activity. In addition, the same techniques are used to monitor other biological or physiological data, including blood pressure.
