Filed: 1997-12-03
Abstract: A system for measuring the non-methane HC concentration of gas sample, e.g.,
automotive exhaust gas, comprising first and second catalytic differential calorimetric
sensors. The first catalytic differential calorimetric sensor is capable of producing a first
output signal representative of the exothermic effect of the oxidation of the predominate
oxidizable species (CO+H 2 + non-methane HC combination) in the gas sample. The
second catalytic differential calorimetric sensor is capable of producing a second output
signal representative of the exothermic effect of the combined oxidation of the
CO+H 2 +alkene hydrocarbon species in the gas sample. Lastly, the system includes a
means for comparing the first output signal with the second output signal, thereby
indicating the total concentration of unburned aromatic and alkane hydrocarbon species
in the gas sample which directly correlates to the total non-methane HC concentration.
A method carried out by the system comprises the following steps: (a) contacting a first
portion of an exhaust gas with a sensor and producing an output signal representative of
the concentration of the predominate (CO+H 2 +non-methane HC species) oxidizable
species in the exhaust gas; (b) contacting a second portion of the exhaust gas with a
second sensor and producing a second output signal representative of the combined
concentration of CO+H 2 +alkene hydrocarbon species in the second exhaust gas portion;
and (c) determining the aromatic and alkane hydrocarbon species concentration, and
thus the total non-methane HC concentration, of the exhaust gas by comparing the first
output signal with the second output signal.

Abstract: Dividing the function of wireless handset control from the function of
telecommunication call control in a software architecture of a wireless
telecommunication system. The wireless handset control function follows the
wireless handset as it registers and is handed off from switch node to switch node;
the telecommunication call control function remains on the switch node on which the

Abstract: A self-clocked apparatus for eliminating race condition in high speed decoders is provided. In multi-stage decoders, a first stage is generally composed of predecoder blocks while a second stage is generally composed of decoder/driver blocks. Each predecoder block receives several address bits and outputs a high or low level signal depending on the address bits state. Each decoder/driver block receives the output signal of the corresponding predecoder block, and outputs a signal selecting or not selecting a connected line. The self-clocked apparatus of the invention is cross-connected between adjacent predecoder blocks such that the ith decoder/driver block is controlled by the i + 1th predecoder block, and conversely. No external clock signal is used, and no time margins is required. Furthermore, the invention provides a robust electrical design.

Abstract: In a phase-locked loop circuit, a vertical synchronous
separation circuit separates a vertical sync signal from a
composite synchronizing signal to detect part of a vertical
synchronizing period. A mask circuit masks the composite
synchronizing signal during a predetermined period. A
selector selects a reference signal or the composite
synchronizing signal in accordance with the detection output
from the vertical synchronous separation circuit. A phase
comparator detects a phase difference between the output
from the selector and the reference signal. A
voltage-controlled oscillator changes an oscillation
frequency upon receiving the output from the phase
comparator through a low-pass filter. A counter counts the
oscillation output from the voltage-controlled oscillator.
A decoder circuit decodes the output from the counter to
generate the reference signal, supplies it to the selector
and the phase comparator, and resets the counter at a
predetermined period. A mask pulse decoder generates a mask
pulse to control a mask period of the mask circuit. The
composite synchronizing signal is replaced with the reference
signal in accordance with the detection output from the
vertical synchronous separation circuit and supplied to an
input of the phase comparator.

Abstract: A high density data storage system based on atomic force microscopy uses a tracking

medium. In a disk drive embodiment with a read-only disk (10), the timing or
tracking lines are formed in sets of triplets with the sets being circumferentially

form the machine-readable data features. The data tracks (60,61,62) and
circumferentially-spaced sets of tracking lines are grouped into radially-spaced bands
on the disk. Each set of tracking lines includes at least two lines, one of which (70)
is a nonradial line. A separate set of identification (ID) marks associated with each
data band are used to initiate a timing gate during which the tracking lines are
expected to be detected. A comparison of the time between the detection of at least
two of the lines with a predetermined target time is used to generate a tracking error
signal (TES) that is used to control the actuator (22) and move the stylus (19) back

Abstract: The present invention concerns a process for preparing a paper web. According to the
process a pulp is formed from a fibrous raw material, a web is formed from the pulp and it
is dried on a paper machine. According to the invention the pulp is formed from a
mechanical pulp produced from a peroxide bleached mechanical wood raw material of the
genus  Populus,  the pH of stock of the mechanical pulp being set at 6.8 to 7.2 and the
machine pH at 7.1 to 7.5 and the conductivity of the stock being set at 1000 to 1500
µS/cm. By using a relatively low pH value and a narrow pH range it is possible to reduce
the sensitivity to disturbances of the paper making process. According to the present
invention a mechanical aspen pulp can be combined with chemical pulp for preparing base
paper of fine paper, whereby the mechanical pulp gives a high conductivity on the machine
which improves the stability of the wet end and enhances water removal.
