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).

A substrate is levitated a first distance over a mother substrate when a first group of Coulomb islands are charged. A second group of Coulomb islands are charged and increase a separation to a second distance. When the magnitude of the potential of all Coulomb islands is decreased, the separation decreases from the second distance to the first distance. All potentials associated with the Coulomb islands have decreased yet the distance of separation equals to the first distance. Increasing the number of Coulomb islands in a substrate can reduce the magnitude of potentials applied to the Coulomb islands thereby reducing the concern of voltage stress.

A movable substrate is placed over a bottom substrate where both substrates contain Coulomb islands. The Coulomb islands can be adjusted in charge and are used to develop a force between two opposing Coulomb islands. Information from sensors is applied to a control unit to control the movement of the movable substrate. Coulomb islands are formed in the juxtaposed edges of a first substrate and second substrate, respectively. The islands generate edge Coulomb forces. These edge Coulomb forces can be used to detach, repel, move, attract and reattach the edges of substrates into new configurations. One possibility is to combine a plurality of individual substrates into one large planar substrate.

A system is described that can assemble substrates over one another to form a stacked substrate. The various layers of the stacked substrate can be separated from each other by using Coulomb forces. In addition, a beam substrate can be used to increase the separation. The instructions for assembly and a FSM (Finite State Machine) can be included in the stacked substrate to pave the way for a self-constructing 3-D automaton. The beam substrate can be used to carry heat, fluids, electrical power or signals between the various layers of the stacked cells besides providing a mechanical support. A stacked substrate can be assembled into a cylindrical coil, a transformer or a coupled transformer depending on the construction of the beam structure. The magnetic coupling of the transformer can be altered by changing the distance between the separated substrates.

Coulomb forces are used to create various metallic shapes within substrates. These shapes are formed by coupling a plurality of substrates together where each substrate contains a metallic pattern. The substrates are assembled together on a mother substrate and the substrates can be positioned either parallel to a planar surface or perpendicular to an edge of the mother substrate. Thus, metallic shapes can be formed that are orthogonal to each other. Such a capability is a desirable feature for antenna construction. The various metal shapes can be used to construct: dipole, patch, Yagi, monopole, bow-tie, meanderline and MIMO antennas. Furthermore, the antenna can be reassembled to adjust the physical dimensions of the antenna while in the consumer product to better match the antenna to a different frequency band.

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.

Several transceivers can be combined together to form a relay which can be used to form an ad-hoc network. A computation unit within the ad-hoc network determines the best placement of a new relay to improve the link integrity of the network. Furthermore, a database of power outlets, their locations and whether they contain a relay or not can be utilized to determine a method to improve the links within the ad-hoc network by placing additional relays into unused power outlets. A control unit can be used to configure the transceivers of each relay to enhance data transfer within a given information flow path of the ad-hoc network. The stream of bits can be exchanged with a second stream of bits. The housing unit can also contain the power plugs molded into the unit to allow the unit to be easily inserted into an AC power wall outlet.

CMOS LC tank circuits and flux linkage between inductors can be used to distribute and propagate clock signals over the surface of a VLSI chip or processor. The tank circuit offers an adiabatic behavior that recycles the energy between the reactive elements and minimizes losses in a conventional sense. Flux linkage can be used to orchestrate a number of seemingly individual and distributed CMOS LC tank circuits to behave as one unit. In one example, the distribution of a 45° separated multi-phase balanced oscillations over the surface of die 1.6 cm×1.6 cm at 10 GHz is expected to dissipate under 10 W and offers a potential to significantly reduce the road map predictions of 100 W. Simulations of several CMOS tank circuits indicate that the power dissipation can be reduced an order of magnitude when compared to conventional techniques. A passive flux linkage, mechanical, and finite state machine technique of frequency adjustment of an oscillator are described.

CMOS LC tank circuits and flux linkage between inductors can be used to distribute and propagate clock signals over the surface of a VLSI chip or μprocessor. The tank circuit offers an adiabatic behavior that recycles the energy between the reactive elements and minimizes losses in a conventional sense. Flux linkage can be used to orchestrate a number of seemingly individual and distributed CMOS LC tank circuits to behave as one unit. Several frequency-adjusting techniques are presented which can be used in an distributed clock network environment which includes an array of oscillators. A passive flux linkage, mechanical, and finite state machine technique of frequency adjustment of oscillators are described.

An integrated circuit comprises a plurality of integrated circuit die arranged in a stack, with a given die other than a top die of the stack carrying current for itself and at least one additional die of the stack via substrate conduction. In one arrangement, each of the die other than a bottom die of the stack carries its power supply current by substrate conduction via a bus or other power supply conductor of an underlying die.
