Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
An integrated circuit die comprises an internal signal pad arranged at a location away from a periphery of the die, a peripheral signal pad arranged proximate the periphery of the die, and a switch coupled between the internal signal pad and the peripheral signal pad. The switch is configurable in at least a first state in which the internal signal pad is not operatively connected to the peripheral signal pad, and a second state in which the internal signal pad is operatively connected to the peripheral signal pad, responsive to a control signal having one of respective first and second signal characteristics. The switch is configured in the first state during normal operation of the integrated circuit die, and is configured in the second state to permit test access to the internal signal pad via the peripheral signal pad.
Abstract:
Techniques are disclosed for automatic generation of a location-indicative instruction displayable to one or more users in a communication system which includes a wireless network comprising a plurality of user devices adapted for communication with at least one access point device. A test of a communication link between at least one of the user devices and the access point device is initiated. Based at least in part on a result of the test, an instruction displayable to a user associated with a given one of the user devices is generated, the instruction being indicative of a location at which the given user device is expected to obtain a particular level of data throughput performance.
Abstract:
A periodic arrangement of magnets are used to form structures that channel the potential energy that a magnet possesses into kinetic energy in a controlled fashion to perform some useful work or function. One function is to create a magnetic chute that converts the potential energy of a magnetic projectile into kinetic energy that is used to channel the projectile to follow a path achieving high velocities along a path. The path is formed by assembling magnets periodically along the path in a certain fashion to create a magnetic chute that allows the magnetic projectile to slide easily along the path since the projectile is confined by the shape of the magnetic chute.
