Communication between controller and addressed target devices over data signal
An addressable interface selectively enables JTAG TAP domain operations or Trace domain operations within an IC. After being enabled, the TAP receives TMS and TDI input from a single data pin. After being enabled, the Trace domain acquires data from a functioning circuit within the IC in response to a first clock and outputs the acquired data from the IC in response to a second clock. An addressable two pin interface loads and updates instructions and data to a TAP domain within the IC. The instruction or data update operations in multiple ICs occur simultaneously. A process transmits data from an addressed target device to a controller using data frames, each data frame comprising a header bit and data bits. The logic level of the header bit is used to start, continue, and stop the data transmission to the controller. A data and clock signal interface between a controller and multiple target devices provides for each target device to be individually addressed and commanded to perform a JTAG or Trace operation. Trace circuitry within an IC can operate autonomously to store and output functional data occurring in the IC. The store and output operations of the trace circuitry are transparent to the functional operation of the IC. An auto-addressing RAM memory stores input data at an input address generated in response to an input clock, and outputs stored data from an output address generated in response to an output clock.

Filtering techniques to remove noise from a periodic signal and Irms calculations
A signal filtering technique is designed to remove the effects of a periodic, low-frequency noise signal from a signal of interest. A signal waveform is sampled at different points of a number of consecutive periodic noise signal cycles and the collected samples are averaged to produce a corrected signal. The number of consecutive cycles in which samples are taken and averaged is inversely related to the signal amplitude such that as the signal level decreases, the number of cycles examined increases. The technique is particularly applicable to periodic signals associated with the output of Hall effect sensors in an electrical metrology environment. Improved RMS calculations are obtained for filtering low-frequency random noise from Hall sensors by averaging samples at different points of a signal cycle to create a composite desired signal cycle to facilitate other signal calculations. In a given electricity utility meter incorporating solid state circuitry, such metrology RMS calculations may be implemented in a metrology section of solid state devices provided on printed circuit boards, such as utilizing programmable integrated circuit components. By varying the number of cycles summed, the algorithm will adapt to amplitude changes more quickly. By using time averaged samples to filter random noise from the periodic signal of interest, the overall requirements for complex filtering is reduced. Instead, the technique relies on buffering and averaging synchronized samples for a given number of line cycles, so that by increasing the buffer size, larger numbers of line cycles can be accumulated and the filter cut-off frequency reduced.

Diaphragm and loudspeaker unit using the same
A diaphragm, and a loudspeaker unit using the same, capable of providing better low-tone characteristics than conventional ones. A loudspeaker unit includes a base frame and a cover plate joined to each other to provide a flat casing. Arranged in the casing are a diaphragm and a drive mechanism for vibrating the diaphragm. The diaphragm consists of a rectangular area and a pair of semi-elliptic areas, spreading rightward and leftward from the rectangular area, and has an elliptic central portion having its major axis in the longitudinal direction of the diaphragm and a peripheral portion spreading around the central portion. The central portion includes an adhesive layer for fixing a coil, laid on a central area of a diaphragm body, and is formed thicker than the peripheral portion.
A speaker of the present invention includes the following: a diaphragm that includes an inner periphery coupled to a voice coil, and a corrugation provided at the intermediate position between the inner periphery and an outer periphery; a speaker edge for supporting the outer periphery of the diaphragm; and a damping member attached to an outer peripheral part of the diaphragm outside the vicinity of an outer periphery of the corrugation. The effective vibration area of an inner peripheral part of the diaphragm inside an inner periphery of the corrugation is substantially half or less of the total effective vibration area. The damping member is configured as a damping portion by extending an overlap portion of the speaker edge overlapping with the diaphragm to the vicinity of the outer periphery of the corrugation. This configuration can suppress the vibration transmission at high frequencies to the outer peripheral part of the diaphragm outside the corrugation, allows only the inner peripheral part of the diaphragm inside the corrugation to mainly vibrate at high frequencies, and also can suppress a resonance in the outer peripheral part of the diaphragm outside the corrugation. Thus, the speaker can have both an excellent high frequency response and an excellent mid-high frequency response.

System for, and method of, processing quadrature amplitude modulated signals
Analog signals encoded with quadrature amplitude modulation (QAM) pass through a coaxial cable at a particular baud rate. These signals have a carrier frequency individual to the TV station being received. They are mixed with signals from a variable frequency oscillator to produce signals at a particular intermediate frequency (IF). An analog-digital converter (ADC) converts the IF signals to corresponding digital signals which are demodulated to produce two digital signals having a quadrature phase relationship. After being filtered and derotated, the digital signals pass to a symmetrical equalizer including a feed forward equalizer (FFE) and a decision feedback equalizer (DFE) connected to the FFE in a feedback relationship. The DFE may include a slicer providing amplitude approximations of increasing sensitivity at progressive times. Additional slicers in the equalizer combine the FFE and DFE outputs to provide the output data without any of the coaxial cable noise or distortions. The equalizer outputs and initially the derotation outputs, and the slicer outputs, servo (1) the oscillator frequency to obtain the IF frequency, (2) the ADC sampling clock to obtain the digital conversion at a rate related to the particular baud rate and (3) the derotator. The servos may have (1) first constants initially after a change in the station selection and (2) second time constants thereafter. The ADC gain is also servoed (1) initially in every ADC conversion and (2) subsequently in every nth ADC conversion where n=integer>1. The above recover the QAM data without any of the coaxial cable noise or distortions.

Single-polarization high power fiber lasers and amplifiers
A novel polarization maintaining optical fiber, which can be used as a high-power polarization maintaining fiber laser or amplifier, is described. Insensitivity of the polarization state to external fiber bending and temperature changes is accomplished by minimizing polarization mode-coupling via reducing stresses inside the fiber core via increasing the fiber diameter. Alternatively, polarization mode-coupling can be minimized by an optimization of the fiber coating to minimize stresses at the interface between the fiber and the coating. As a result insensitivity to polarization mode-coupling is obtained at greatly reduced values of birefringence compared to small-diameter fibers. The fiber is of significant use in any application where polarization stability is important, and will be useful in telecommunications applications in particular for reducing polarization mode dispersion. An implementation in a parabolic pulse-producing fiber laser is also described as one specific high power example.
System and method for voice transmission over network protocols
A system and method for voice transmission over high level network protocols. On the Internet and the World Wide Web, such high level protocols are HTTP/TCP. The restrictions imposed by firewalls and proxy servers are avoided by using HTTP level connections to transmit voice data. In addition, packet delivery guarantees are obtained by using TCP instead of UDP. Variable compression based on silence detection takes advantage of the natural silences and pauses in human speech, thus reducing the delays in transmission caused by using HTTP/TCP. The silence detection includes the ability to bookend the voice data sent with small portions of silence to insure that the voice sounds natural. Finally, the voice data is transmitted to each client computer independently from a common circular list of voice data, thus insuring that all clients will stay current with the most recent voice data. The combination of these features enables simple, seamless, and interactive Internet conferencing.

Method and arrangement in a telecommunication system
The present invention relates to methods and arrangements in a multi-antenna radio communication system, in particular to methods and arrangements for improved multiple HARQ transmission in such systems. While HARQ transmission schemes, as known in the art, only can consider the fact whether or not a transmission attempt has been successful the present invention provides a HARQ retransmission scheme that considers the reception quality for already performed transmissions of a same data packet when selecting a resource allocation for necessary re-transmissions. Resource allocation for retransmissions is based on a pre-defined metric indicating a quality of the reception of the previous transmission attempts. Such a metric can be derived from a quality measure derived in the receiver unit, e.g. a CQI or CSI-based value, or an appropriate measure of the mutual information, e.g. the accumulated conditional mutual information (ACMI).
In a communication system subject to variations in channel quality, transmit power control is used to reduce the variations in received signal quality. If the channel quality degrades to such an extent that a high transmit power would be required to ensure good received signal quality, the transmit power is decreased and is not increased until the channel quality recovers sufficiently to enable an acceptable transmit power level to be used. While the power is at the decreased level, transmission of a data block may continue, or may be suspended, with the data block being truncated if the whole block has not been transmitted by the end of the time period available for transmission of the data block.

The method also includes printing a print job to the tangible medium based on the subset of the plurality of initial halftone patterns. For example, a print controller may be reprogrammed with the subset of the plurality of initial halftone patterns to print a print job to reduce the amount of ink applied to the tangible medium.
Image data management processing apparatus, medium recording image data management processing program and image data management processing method
There has been a problem in that original image data should be saved with another name so as not to be altered, resulting in complexity and an increase in a necessary storage region.Image data are housed in a folder managed as a film metaphor and a database of photographic data 30b corresponding to each image data is prepared. When a desirable image processing is selected for desirable image data, the selected image processing is updated as modification information in the database structure. When display, output or print is actually required, various image processings are executed by referring to modification information on only a work area with original image data left. Therefore, it is possible to easily enjoy image modification or the like with the original image data left as they are.

On-chip polarimetry for high-throughput screening of nanoliter and smaller sample volumes
A polarimetry technique for measuring optical activity that is particularly suited for high throughput screening employs a chip or substrate (22) having one or more microfluidic channels (26) formed therein. A polarized laser beam (14) is directed onto optically active samples that are disposed in the channels. The incident laser beam interacts with the optically active molecules in the sample, which slightly alter the polarization of the laser beam as it passes multiple times through the sample. Interference fringe patterns (28) are generated by the interaction of the laser beam with the sample and the channel walls. A photodetector (34) is positioned to receive the interference fringe patterns and generate an output signal that is input to a computer or other analyzer (38) for analyzing the signal and determining the rotation of plane polarized light by optically active material in the channel from polarization rotation calculations.
