Abstract: An apparatus for driving a throttle valve (4) with a stepping motor (40) in a diesel engine (1). The apparatus includes a fully open detection switch (39) that is shifted between ON/OFF states by motion of the valve (4) when the valve (39) moves near a fully open position. An ECU (19) initializes a relationship between the driven step number of the stepping motor (40) and the angular position of the throttle valve (4) by setting a reference angle of the stepping motor (40) only when the fully open switch (39) shifts from an OFF state to an ON state, not vice versa. Thus, the reference rotational angle of the stepping motor (40), which corresponds to the fully open position of the throttle valve (4), is located accurately regardless of hysteresis errors that occur when the fully open switch (39) shifts between ON/OFF states. Accordingly, the angular position of the throttle valve (4) is controlled more precisely.

Abstract: A brushless DC motor 46 modifies motor commutation events
to reduce noise by providing overlapping activation of the switch being
deactivated with the switch being newly activated so that three switches are
temporarily activated. The newly activated switch is pulse width modulated
with a motor torque controlling duty cycle, and the switch being deactivated is
pulse width modulated synchronously with the newly activated switch but with
a duty cycle decreasing from the torque controlling duty cycle. The
decreasing modulation of the switch being deactivated allows a slower current
decrease in the phase turning off to reduce or eliminate the disturbances, and
thus the noise. The decreasing modulation is preferably exponential in
manner, with a time constant varying inversely with motor speed so that the
duty cycle reaches a predetermined minimum in a predetermined maximum
number of motor electrical degrees. The decreasing modulation may be
switched on at low motor speeds where its noise reduction is required and
switched off at higher motor speeds where the potential for interference with
commutation is greater. The decreasing modulation is applicable in a dual
switching mode in which each activated switch, except for the switch being
deactivated in commutation, is pulse width modulated at the torque controlling
duty cycle, or in a modified single switching mode in which the activated
switch of one of the upper or lower groups is always closed continuously
during its activation, except for commutation, during which the switch
remaining on, which alternates between the groups, is closed continuously.
Each mode of operation is applied in the motor speed/torque region to which it
is best suited.

Abstract: An information extractor for extracting subsets of
text sequences having certain attributes from a semi-structured
text sequence. The information extractor
resembles a finite state transducer that includes a number
of states and transition paths between the states. Each
state is defined to be associated with the extraction of
subsets of tokens having a certain attribute. Each
transition path represents a possible transition from one
subset of tokens having a certain attribute to another
subset of tokens having another attribute. Contextual
rules are used to determine when a transition occurs and
which transition path to take. By using contextual rules
that consider the token patterns before and after a token,
the information extractor can process documents with
irregular layout structures and attributes having a greater
variety of permutations. 
     The state transition diagram, used in one embodiment
of the information extractor, represents the different
sequence of states that the extractor may go through when
it extracts attributes  U,N,A  and/or  M  from an entry in the
input text sequence. The extractor starts in state  b/e 
202, then reads a token and determines whether the token
belongs to an attribute. For example, the first attribute
within an entry must be either  U  or  N . Hence, there is one
transition path 218 from state  b/e  202 to state  U  204, and
another transition path 220 from state  b/e  202 to state  N 
208. If the token does not belong to either attribute  U  or
 N , then the extractor remains at state  b/e  202, shown by
the path 224.

Abstract: A method that selects one of a plurality of priority schemes for scheduling messages for
one of cyclically repeating sets of time slots of a control channel based on at least one of a
plurality of characteristics of the state of the control channel (10). The state of the control
channel (10) is the all information regarding what has arrived, what is queued, and what has been
transmitted. This includes the status of the queues, the messages awaiting transmission, along
with their type and the time they have been waiting, the sequence of past transmissions, as well as
other information. In one embodiment, in a control channel of a TDMA system where the
hyperframe number is the characteristic used to select the priority scheme, a priority scheme is
selected that assigns a voice page highest priority when the hyperframe number is an even
number, and that assigns an R-DATA SPACH notification highest priority when the hyperframe
number is an odd number. In another embodiment of the invention, if there is a packed airlink
message, the packed airlink message is scheduled in the time slot. If there are no packed airlink
messages, then the method dynamically alters the priority of messages based on whether there is a
voice page or an R-DATA SPACH notification in the message queues since at least the end of the
time slot construction period of a corresponding time slot of a previous hyperframe. If there are
no such messages and there is a non-packable message, the non-packable message is scheduled in
the time slot, although if there are no non-packable messages and there is a voice page or R-DATA
SPACH notification, it is packaged in an unpacked airlink message that is scheduled in the
time slot. However, if there is a voice page or an R-DATA SPACH notification in any of the
message queues since at least the end of the time slot construction period of the corresponding
time slot of the previous hyperframe, the voice page or R-DATA SPACH is packaged in an
unpacked airlink message that is scheduled in the time slot. This significantly reduces both the
number of messages that are blocked and the number of messages timed out.

Abstract: The invention provides methods and apparatus for processing information, e.g.,
audio, video or image information, for transmission in a communication system. In an
illustrative embodiment, the value of a single-bit or multiple-bit criticality flag is determined
for each of the programs in a set of multiple programs to be transmitted in the system. The
information bits for each of the programs are then separated into n classes, where n is
greater than or equal to two, based on the values of the criticality flags for the programs.
Each of the classes is provided with a different level of error protection, e.g., through the
use of different convolutional codes or other suitable techniques. The program or programs
having the highest criticality flag values in a given frame or other designated time interval
thus have a larger percentage of their information bits assigned to the class that is provided
with the highest level of error protection. The assignment of the multiple program bits to
the classes, as well as the characteristics of the classes, may be fixed for a designated
number of program frames, or dynamic, i.e., permitted to vary from frame to frame.
