The noise signal is generated so that the output audio signal exhibits an excitation pattern nearly identical to the original audio signal. Thus, a perceived high quality audio is obtained while the encoded signal is scalable since a possible deviation between encoding and decoding of the first signal part is compensated by the noise generator at the decoder side. In preferred embodiments the coding means comprises a sinusoidal coder.

Pulse mode modulation in frequency converted laser sources
Methods of operating a frequency-converted laser source are disclosed. According to particular disclosed embodiments, a laser diode is driven in a pulsed mode to define pixel intensity values corresponding to desired gray scale values of image pixels in an image plane of the laser source. The pixel intensity values are a function of a laser control signal comprising a discontinuous pulse component, a relatively constant intensity component I, and a continuously variable intensity component I*. The pulse width w of the discontinuous pulse component is selected from a set of discrete available pulse widths according to a desired pixel gray scale value.

The relatively constant intensity component I makes a relatively insignificant contribution to pixel intensity at the low-end pulse width w for the range of low-end pixel gray scale values and assumes a non-zero value for enhanced conversion efficiency at the progressively larger pulse widths w established for the higher pixel gray scale values. The continuously variable intensity component I* varies according to the desired gray scale value of the selected pixel and the contributions of the relatively constant intensity component I and the pulse width w to pixel intensity.

Method for updating a data record and device for carrying out the method
When updating a data record identified by a version number, the problem exists that a simple not equal to comparison or greater than comparison is often insufficient for ascertaining the up-to-date nature of the newly received data record, particularly if the data record is transmitted to a receiving station via an unsecured data link and the version number originates from a limited range which is repeatedly run through periodically.The invention solves the problem by virtue of the fact that it divides the range of values of the version number into the ranges “old” and “new”, on the basis of the current value of a version number.

Network adapter with TCP support
A network adapter and corresponding method for its use are disclosed. The network adapter has an operational mode that allows a host CPU to offload transmission of a block of data to the adapter. The adapter segments the block into fragments, and builds a data packet for each fragment. The adapter transmits these packets with an adapter-implemented flow control. This flow control uses: a context engine that tracks flow control variables for a “context” established for the block; a context memory for storing the variables; and a receive filter that updates flow control information for the block based on ACK packets received from the remote endpoint receiving the data packets. Because the network adapter implements flow control for data blocks that the network adapter segments, intermediate ACK packets corresponding to that block can be intercepted by the adapter, before they pass to the host, conserving host resources. An added advantage is that the host CPU can offload data blocks larger than the remote endpoint's receive window size, since the adapter can follow the transmit window and transmit packets at appropriate intervals. This further decreases load on the host CPU, decreases latency, and improves bandwidth utilization.

Digital interface sensing apparatus
A digital interface sensing apparatus includes a sensor, an analog detecting circuit, an analog to digital (A/D) converter, a signal cable, and an interface switch circuit. The sensor senses an external analog signal. The analog detecting circuit detects the sensed analog signal from the sensor. The A/D converter converts the sensed analog signal to a digital signal and receives a clock signal and a data demand signal. The A/D converter sends the digital signal in response to the A/D converter receiving the clock signal and the data demand signal. The interface switch circuit includes a multiplexer and a recommended standard 422 (RS-422) transceiver. The RS-422 transceiver is connected between the A/D converter and the multiplexer to switch RS-422 digital signal and transistor-transistor logic (TTL) signal. The multiplexer is connected between the A/D converter and the signal cable to selectively transfer RS-233 and RS-422 signals.

In another embodiment, the proper termination is set or measured by adjusting the termination value to achieve maximum power dissipation in the terminating device. The equivalent characteristic impedance measurement may be used to count the number of metallic conductors connected to a single connection point.

Verification of a fabrication process used to form read elements in magnetic heads
Test methods and components are disclosed for testing the quality of a fabrication process used to form read elements in magnetic heads. A wafer is populated with one or more test components along with magnetic heads. The test components are formed by the same or similar fabrication processes as the read elements, but do not include a conductive MR sensor between the test leads. By measuring the resistance of the test components, the formation of parasitic shunts can be identified in the test components, which may indicate the formation of parasitic shunts in the read elements. Thus, the quality of the fabrication process in forming read elements in magnetic head may be determined.
