Title: Apparatus, methods and computer program products for sequential maximum likelihood estimating communications signals using whitening path metrics
Inventor: RAMESH RAJARAM
IPC: H04L27/01
Filed: 1997-12-31
Granted: 2000-12-21
Abstract: An estimate of a first symbol sequence is estimated from a communications signal communicated over a communications channel which imparts noise to the communications signal. The communications signal is received from the communications channel and processed to produce a second symbol sequence. A whitening function is identified, preferably a whitening filter impulse response, and an estimate of the first symbol sequence is sequential maximum likelihood estimated from the second symbol sequence using a path metric including the whitening function. Preferably, candidate symbol sequences are generated for survivor symbol sequences, each candidate symbol sequence including the survivor symbol sequence and an additional symbol postulate. A path metric is determined for each candidate symbol sequence from the candidate symbol sequence, the second symbol sequence, the branch metrics of the symbol postulates in the associated survivor symbol sequence, the whitening filter impulse response, the path metric of the associated survivor symbol sequence and a channel impulse response. At least one new survivor symbol sequence, preferably one with a lesser path metric, is selected from the candidate symbol sequences. The path metric preferably is determined by accumulating branch metrics. Each branch metric preferably is determined by convolving the candidate symbol sequence and the channel impulse response, subtracting the convolution from the second symbol sequence to produce an error sequence, and determining a weighted sum of error sequences for the candidate symbol sequence, weighted according to the whitening filter impulse response. A magnitude of the weighted sum is computed to thereby compute a branch metric.

Title: NCO based frequency synthesizer with jitter modulation
Inventor: WOLF CHRISTOPHER K
IPC: H04N21/43
Filed: 1999-05-18
Granted: 2003-04-21
Abstract: An improved synchronization circuit has a numerically controlled oscillator (NCO) having an accumulator, a number line, and feedback line fed back from the accumulator output. The accumulator repeatedly adds the number represented on the number line and the number represented on the feedback line and feedbacks the result to the accumulator. The result rolls over to zero as would an odometer when it reaches a maximum value. When the number represented on number input is properly selected by, for example, a microprocessor, a data stream representing the most significant bit of the result has jitter. The synchronization circuit also has a phase-locked loop (PLL) configured to receive the data stream of the most significant bit. The frequency of the most significant bit stream and the frequency of the jitter on that bit stream are controlled by the number at the number input. The number is chosen to maximize the jitter frequency and thus maximize jitter attenuation through the PLL.

Filed: 1999-09-17
Granted: 2001-05-16
Abstract: This invention provides a transmission controller to make the gear ratio of a transmission smoothly follow a vehicular speed, not only when a change in the actual vehicular speed is transited slowly, but also even when the change thereof is transited suddenly. The simple structure of this controller has a speed detecting means 1 for outputting a speed signal of a measured vehicular speed as pulse signals, and a control part 2 for calculating the vehicular speed based on pulse intervals of the taken-in pulses to output a control signal. A gear ratio transition table is stored in the control part 2. At least two kinds of imaginary speed conditions corresponding to a low speed side gear ratio of a transmission and a high speed side gear ratio in its adjacent shifting position are set in the gear ratio transition table, and speed values different at the time of acceleration shift and at the time of deceleration shift are set between the imaginary speed conditions. The speed value at the time of the deceleration shift is made smaller than that at the time of the acceleration shift.

Title: Method and apparatus for cutting a laminate made of a brittle material and a plastic
Inventor: HABECK ANDREAS DR
IPC: C03B33/023
Filed: 1999-11-09
Granted: 2004-03-21
Abstract: A description is given of a method and an apparatus for cutting a laminate made of a brittle material and a plastic with a cutting tool. The plastic is heated up, thereby lowering its viscosity, at least in the region of a predetermined cutting line. A cutting tool is placed onto the plastic side of the laminate, the loading pressure being adjustable. By producing a relative movement between cutting tool and laminate along the predetermined cutting line, the plastic is severed; at the same time the brittle material is scored, thereby inducing a mechanical stress. If appropriate, the mechanical stress along the cutting line is subsequently increased to beyond the rupture strength of the scored brittle material. A preferred application is the cutting of thin glass or glass-ceramic/plastic laminates.

Title: Medium and method for recording optical information
Inventor: TAKAGISHI YOSHIKAZU
IPC: G11B7/24
Filed: 2000-02-11
Granted: 2002-01-11
Abstract: The present invention provides a medium for recording optical information that allow the recording sensitivity to be increased, and particularly a prescribed recording sensitivity to be maintained together with reflectivity and other playback characteristics during high-speed recording, by employing the temperature dependence of the recording sensitivity of the light-absorbing layer instead of the light attenuation coefficient of the light-absorbing layer, and selecting a material which is prone to increased absorption of a laser beam at high temperatures during recording. A distinctive feature is that the absorbance or recording sensitivity of the dye material film used in the medium for recording optical information that has a writable structure is dependent on the temperature. Specifically, it was found that the absorption spectrum of the dye material varies at high temperatures, and a relation A2/A1 ≥ 1.30 was established. In this relation, A1 (Abs) is an absorbance of the light-absorbing layer at a wavelength of recording light under room-temperature conditions, T (DEG C) is a pyrolysis temperature of the light-absorbing layer, and A2 (Abs) is an absorbance at a wavelength of recording light under T (DEG C), T-50 (DEG C) conditions.

Title: Inductive system and a method of making a variable inductive system
Inventor: SWOPE CHARLES B
IPC: H01F21/04
Filed: 2000-11-14
Granted: 2003-08-11
Abstract: A variable inductor is made from two elements separated by an insulating layer. The first element is elastic and serves as a coil shaped support for the inductive element. This elastic element is made with a memory and can be made to change its size by the application of heat. The inductive element is formed over the coil shaped support by layering a thin layer of a highly conductive material such as gold over the insulator layered on the elastic element. As heat is applied to the coil or as an electric current is applied to the elastic element, the size of the coil shaped support is changed which changes the inductive value of the inductive element formed by the conductive layer.
