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.

Method and apparatus for automatic determination of optimal user device location in a wireless network

In one embodiment, an apparatus comprising a housing and a fastener, such as a clip () for fastening the apparatus () to an article of clothing. The housing () has a recess () formed therein, such that at least a portion of the fastener is adapted to fit within the recess. The fastener is adapted to travel slidably within the recess () between a first position in which the fastener enables the apparatus () to be fastened to an external object and a second position in which the fastener is stowed away.

A method and apparatus are provided for wireless communication between an integrated circuit device and a monitoring station. Each integrated circuit device has one or more antennas that permit wireless communication with an external monitoring station. A signal destined for an integrated circuit device is transmitted by the monitoring station using an associated antenna. An antenna associated with the destination integrated circuit receives the transmitted signal. The antenna(s) may be embodied, for example, as pins that are external to the integrated circuit device, or printed or etched on the integrated circuit device itself. Greater bandwidth can be achieved, if necessary, by pooling the bandwidth of several antennas.

Method and system for wireless communication with an integrated circuit under evaluation

Embodiments of the present invention generate a normalized floating-point sum from at least two floating-point addends. The mantissa of an un-normalized floating-point sum is generated. A pointer is generated which indicates the location of the left-most significant digit (LSD) in the mantissa of the un-normalized floating-point sum. A plurality of possible values for the exponent of the normalized floating-point sum are generated, in parallel with each other and in parallel with the mantissa addition, based on a common exponent value (e.g., the largest of the two addends' exponent values). Based on the LSD pointer, one of the possible values is selected as the exponent of the normalized floating-point sum. The mantissa of the un-normalized floating-point sum is normalized to yield the mantissa of the normalized floating-point sum. By generating the possible exponent values in parallel, embodiments of the present invention can result in significant time savings over prior-art methods.

A passive mixer includes a transconductance amplifier having a source degeneration capacitance. The transconductance amplifier has an input for receiving an input signal and an output for outputting a current signal. A multiplier is provided for mixing a local oscillator signal with the current signal so as to provide an output signal at an output of the passive mixer. A capacitive load is connected to the output of the passive mixer.

There is disclosed an input device including a display for displaying a plurality of icons, and a selector for selecting a displayed icon. At least a portion of the display is an electronic display. The device is adapted such that the selector moves relative to the display between a plurality of positions. At least one position corresponds to a displayed icon. The device further includes a function selection means. A function associated with an icon corresponding to a current position of the selector is selected when the function selection means is enabled.

In one embodiment, an amplifier circuit has at least one branch and current-source circuitry providing a tail current to the branch, which has at least one load tank, at least one input transistor coupled to the load tank, and variable-impedance circuitry coupled between an input node of the amplifier circuit and the gate of the input transistor. The transconductance of the input transistor can be altered to achieve two or more different gain settings for the amplifier circuit. The variable-impedance circuitry can be controlled to contribute any one of at least two different levels of impedance to the overall input impedance of the amplifier circuit. If the transconductance of the input transistor is reduced, then the variable-impedance circuitry can increase the level of impedance contributed to the overall input impedance of the amplifier circuit such that the overall input impedance of the amplifier circuit remains substantially unchanged.

A system for, and method of, obscuring ambient noise. In one embodiment, the system includes: (1) a background sound generator, (2) a mixer coupled to the background sound generator and (3) a user interface, coupled to the mixer, that, upon a user command, causes the mixer to mix an output of the background sound generator with a transmitted signal. The background sound may be music, white noise, colored noise, out-of-phase ambient noise, simulated alternative ambient noise or any other suitable background sound. The system may be associated with a wireless handset, a wireline handset, central office equipment or any other suitable location or equipment.

A charge meter system and method of compiling utilization fees associated with a data transmission in a packet switched communications network. In one embodiment, the charge meter system includes a counter that counts a number of data packets associated with the data transmission and a charge rate subsystem that obtains a charge rate associated with the data transmission. The charge meter system also includes a calculation subsystem that calculates utilization fees based on the number of data packets and the charge rate of the data transmission. The charge meter system further includes an indication subsystem that provides the utilization fees to a user via user equipment participating in the data transmission.

Charge meter system and method of compiling utilization fees

An application-specific single chip digital processor having flexible design expansion capability with minimal impact on the performance of a processor core. The processor core has an ALU and a register file (accumulators). The output of the ALU is connected to a multiplexer whose output is connected to the input of the register file. The output of the register file connects to one input of the ALU. A function unit, separate from the core, has an input connected to the output of the register file and an output connected to another input to the multiplexer. The core operates with a predefined instruction set. The function unit, which may be redesigned depending on the application, operates with a reserved (uncommitted) instruction set under control of the core.
