A remote recording unit, which is worn by a child, monitors the ambient sounds in a day care center (for example) and records selected sound bytes that are played back on a docking unit. The time duration between sound bytes is periodic and re-programmable. The remote recording unit is 'childproof' and tamper-evident to generate an internal 'flag' which will be displayed on the docking unit, indicating that the remote recording unit was removed by an unauthorized person. The device is equally applicable to a patient, older person or pet left in the care of a third person or persons or placed in a facility or institution.

Apparatus and method for monitoring and recording the audible

A phased array includes a first plurality of radiators having a first polarization and a second plurality of radiators having a second polarization, different from said first polarization. The phased array is constructed such that radiating patterns of the first and second plurality of radiators are congruent. The radiators are constructed so that they radiating apertures thereof can occupy virtually the same space, i.e., the spacing of the radiating elements is less than a wavelength. Other features provided allow this compactness to be achieved. Impedance matching features are integrated into the radiators themselves. The elevation assemblies of the radiators are mated together, and then are coupled across to their respective azimuth assemblies. Two azimuth assemblies for either type of polarization may be provided when monopulse operation is required. Assemblies for both polarizations transmit sequentially, but receive simultaneously, thus allowing a complete polarization matrix to be collected with two pulse transmissions.
