  • Patent number: 6701269
    Abstract: Error-related information acquired using a bit error ratio detector (BERT) is extrapolated on the basis of prior testing, in which measurements “superior” to those acquired by the BERT are used to provide an initial extrapolation calibration. For example, measures of data dependent jitter acquired by a digital communications analyzer (DCA) may be used to offset the less accurate jitter-related measures by the BERT. As a consequence, the benefits of a DCA and a BERT are combined, while using only the BERT.

  • Patent number: 6700516
    Abstract: Signal sampling is performed. A sampler takes samples of a sampled signal. A first analog-to-digital (A/D) converter receives the samples from the sampler. A clock reference is synchronous with the sampled signal. A phase comparator produces a difference value that indicates a phase difference between the clock reference and an oscillating signal. A second A/D converter receives the difference value. The oscillating signal is used in controlling when the sampler takes samples of the sampled signal.

  • Publication number: 20040036889
    Abstract: In order to reduce polarization dependent error, the polarization state of incident light is set to at least two different states of polarization, and a first optical property is determined separately for each of said at least two states of polarization. Then, an averaging procedure is carried out in order to obtain a mean value of the first optical property or of a property derived therefrom. Alternatively, the averaging procedure can be performed with respect to a DUT property of a device under test that is determined as a function of said first optical property.

  • Patent number: 6696710
    Abstract: A heterojunction bipolar transistor (HBT) having a base-emitter junction that exhibits the desirable properties of a GaAsSb/AlInAs interface, but which includes an intermediate layer in the emitter such that the intermediate layer contacts the GaAsSb base and the AlInAs emitter. The intermediate layer is sufficiently thin to be substantially electrically transparent, but sufficiently thick to provide a surface over which to grow the AlInAs emitter. The intermediate layer may be of a material such as InP, which has a bulk lattice constant that matches the lattice constant of the GaAsSb base and the AlInAs emitter. Alternatively, the intermediate layer may be of a material having a lattice constant different than that of the GaAsSb base and the AlInAs emitter, but may be pseudomorphically grown so as to provide an apparent lattice-match to the GaAsSb base and the AlInAs emitter.

  • Patent number: 6695006
    Abstract: A flow control includes a support having a passage and a seal surface, a deformable seal that is engageable with the seal surface, and a bias member for exerting a variable bias against the deformable seal. The seal surface includes channels formed in its surface that extend beneath the deformable seal. The bias member can exert a bias sufficient to cause the deformable seal to fill the channels, preventing fluid flow through the channels. When the bias member decreases the bias against the deformable seal, the deformable seal gradually moves out of the channels, allowing fluid flow through the channels, and through the passage in the flow control. The deformable seal does not need to separate from the seal surface to allow fluid flow. Instead, fluid flows through the small, controlled flow areas created when the deformable seal withdraws from the channels.

  • Patent number: 6696223
    Abstract: A method for generating a photoresist pattern on top of an object that includes a layer of material that is opaque to light of a predetermined wavelength. The object is first covered with a layer of photoresist material. The layer of photoresist material is then irradiated with light of the predetermined wavelength from a position under the object such that the object casts a shadow into the layer of photoresist. The photoresist material is then developed to generate the photoresist pattern. The layer of photoresist material is irradiated from below the object by providing a reflecting surface below the object and a light source above the object. A mask is positioned between the object and the light source such that the mask casts a shadow that covers the object and a portion of the area surrounding the object.

  • Patent number: 6696878
    Abstract: A method and apparatus for interfacing two voltage domains is presented. In one embodiment of the present invention, a method and apparatus for interfacing a high voltage domain with a low voltage domain is presented. In one embodiment of the present invention, high output signals and low output signals are generated with a level-shifter. The level-shifter is used to interface the two domains. The low output signals are generated using a low-voltage driver and a first clipping stage. The high output signals are generated using a high-voltage driver and a second clipping stage. Duty-cycle distortion is lowered or eliminated by using an accelerator to accelerate the transition between the high output signals and the low output signals. Bias signals are input into the first and second stage. The bias signals work in a coordinated manner, to constrain the minimum and maximum outputs of various components in the level-shifter.

  • Patent number: 6693918
    Abstract: A solution to the word alignment problem in a Serializer Deserializer (SERDES)/Media Access Controller environment is to have for each SERDES lane: a recovered clock, a Write Pointer counter and a FIFO. Misaligned words are simply stored in their FIFO's according to the respective recovered clocks and straightforward increments of the various Write Pointers WP_i. One of the lanes is selected as a reference, and the contents of the other FIFO's are inspected to determine the nature of their misalignment, if any. Then the values from the Read Pointer counters RP_i are individually offset by corresponding amounts to compensate for the misalignment, so that when data is read it is indeed aligned. These offsets by corresponding amounts are simply individual per lane adjustments to the various Read Pointers, and cooperate with the adjustments to those Read Pointer for rate matching.

  • Patent number: 6694001
    Abstract: Methods to identify inter-carrier telephone calls in a telephone system that are being mis-routed in such a way as to violate existing regulatory tariffs and/or established inter-carrier contracts. The common name for this manipulation is “arbitrage”, and the intent of the perpetrators is to take advantage of lower rates associated with the delivery of telephone traffic via other routes. Through the processes of collecting call detail records and their correlation in representative embodiments, various call “legs” associated with the same call can be identified, and a more accurate “compound” call record can be made that incorporates call routing information obtained from the individual call legs. A statistical analysis can then be performed to more clearly illuminate any arbitrage.

  • Patent number: 6693937
    Abstract: An integrated tunable laser structure comprising a substrate made of semiconductor material, the substrate comprising a first, a second, and a third section. The first section provides a low-selective interferometric filtering together with an amplification of a light wave resonating in the laser structure. The second section provides continuous fine-tuning and phase adjustment of the light wave, and the third section provides a wavelength selective reflection of the light wave. Each section allows current injection, wherein a current into the first section causes a wavelength shift of the low-selective interferometric filtering, a current into the second section causes a wavelength shift of resonator modes, and a current into the third section causes a wavelength shift of the wavelength selective reflection.
