An electronic seal including an electronic tag, an electrically resistive element in electrical communication with and attached to the tag, the resistive element being bondable to an object so as to define an electrical resistance, wherein a change in bonding of the element to the object causes a change in the electrical resistance, the change in electrical resistance being communicated to the tag.

An FM receiver includes an FM discriminator having a comparator for converting the FM signal to a series of discrete square-wave pulses all of the same amplitude and of a repetition rate varying with the frequency of the FM signals; and an integrator circuit which integrates the series of monopolar square-wave pulses to produce an output signal having an amplitude varying with the repetition rate of the square-wave pulses. Also described are FM stero systems including the above FM discriminator in its audio channels.

FM receiver and communication systems including same

The described hearing aid includes a frequency analyzer for classifying incoming sounds according to their frequency, and for selecting an appropriate transposition factor (the ratio of the information storage rate to the information retrieval rate) according to the appropriate one of several transposition factors inputted into the hearing aid based on the particular user's hearing characteristics for different frequencies. Also, described is an arrangement for minimizing loss of speech components containing the same frequency information by recirculating such speech components. Further described is an arrangement for reconstructing portions of the speech components according to their classification by the frequency analyzer in order to minimize loss of useful information in the output signal.
