摘要： Methods and apparatus are provided for preventing a third party from listening to a conversation between at least two participants on a telephone. The telephone generates an audio stimulus signal that is presented through a secondary speaker. The audio stimulus signal may be, for example, pseudorandom noise or a cancellation signal. According to one aspect of the invention, the telephone ensures that the audio stimulus signal does not significantly impair the conversation for the at least two participants. To prevent the third party from listening to the local portion of the conversation, the audio stimulus signal is subtracted from the received signal prior to presenting the received signal to the user. To prevent the third party from listening to the remote portion of the conversation, the audio stimulus signal is subtracted from the received signal.

摘要： Electronic modules are interconnected with one another by means of communication (e.g., ultrasonic) links, In one embodiment, in a local conference call environment, only one wireless RF link is necessary—between a master cell phone and a base station, whereas all other voice modules are interconnected with one another and with the master via ultrasonic links. In another embodiment, a master voice module (with or without an RF link to a base station) includes at least one detachable module (e.g., an earpiece and/or mouthpiece) that is interconnected with the master via an ultrasonic link. In yet another embodiment, a detachable module includes a capacitor, which serves as its power supply and which is recharged when it is attached a master module (e.g., by a battery in the master module).

摘要： Power amplifiers are disclosed that demonstrate improved linearity and efficiency in applications requiring significant peak-to-average ratios (PAR). A power amplifier in accordance with the present invention comprises a first transistor in an input stage that converts DC power into AC power; and a second transistor in a negative conductance stage that has a current-voltage characteristic with at least two slopes. The at least two slopes of the current-voltage characteristic are separated by a break point that may be controlled. The power amplifier may also include a non-dissipative two-port device that has two AC ports. The non-dissipative two-port device has a Z matrix with two zero-valued diagonal elements and two complex valued off-diagonal elements having a same sign and only imaginary parts for an operating frequency. In one implementation, the diagonal entries of the Z matrix are small at twice the operating frequency.

摘要： A power device(s) is biased and operates in Class-AB. Crossover distortion is minimized over a broad range of operating conditions, not only for a nominal case. The bias current of a power transistor is automatically adjusted in response to process and temperature variations. Preferably, the adjustment is performed using an error-feedback arrangement. An exemplary ‘rule’ for bias adjustment involves satisfying a proportionality relationship between the small-signal device transconductance at the operating point, and a maximum device transconductance. A dual replica master-slave control architecture is utilized. A self-adapting circuit is provided to change the bias current (or voltage) so that the value is always the optimum value, irrespective of operating temperature and/or process variations. Self-biasing is introduced wherein no manual adjustment is necessary. A stable amplifier is formed having great robustness to process and temperature variations.
