Abstract: Systems and methods allow for more efficient wireless networking. In one system, plural subscriber units form a direct network and transmit and receive without base station mediation. In another system, base stations are networked so that one base station can take advantage of the second, networked, base station. In one example, high-capacity lines are connected to one base station which is then networked to a second base station. Through the network, the second base station can utilize the high-capacity lines without being directly connected to them. In another example, the subscriber units can migrate between all base stations in the network. In another example, using networked base stations and unassigned time sequences or codes, calls can be dynamically reassigned between base stations to meet shifting demand.

Abstract: A system integrates a hearing aid with devices such as wireless telephones, advantageously avoiding radio frequency (RF) interference. In one embodiment, a processor transforms an electrical signal to compensate for a hearing impairment. The function used for signal transformation can be accessed via a processor memory enhancement such as a smart card. A digital-to-analog converter (DAC) converts the transformed signal to an analog signal, which then goes to an amplifier and speaker. In other embodiments, an analog amplifier transforms the electrical signal.

Abstract: A probe for measuring an electromagnetic field is described. A sensing element senses the electromagnetic field and generates a sensing signal indicative thereof. The sensing signal is characterized by a first modality. First conversion circuitry coupled to the sensing element converts the sensing signal to a second modality.

Measurement circuitry coupled to the transmission medium receives the sensing signal in the second modality and generates measurement data corresponding to the electromagnetic field.

Abstract: Polyol polyesters useful as nondigestible fat substitutes are prepared by improved heterogeneous interesterification processes between fatty acid esters of easily removable alcohol and polyol wherein the particle size of the polyol is reduced to less than 100 microns, and when the degree esterification of the polyol is between about 15% and no more than 75% substantially all of the unreacted polyol is removed. In the initial or early stages of the reaction, reaction conditions are adjusted to maintain a sufficient level of lower partial fatty acids to act as an emulsifier. The initial catalyst level is from about 0.001 to about 0.5 catalyst per mole of catalyst.
