Abstract: A digitally-controlled oscillator (DCO) (60), such
as may be used in clock generator or clock recovery
circuitry in an integrated circuit, is disclosed. The
disclosed DCO (60) is a single-stage oscillator including
a variable load implemented as a binary-weighted array of
switched capacitors (40). Each of capacitors (40) has a
plate connected to a common node (X), and a plate that
receives a signal corresponding to one bit of a digital
control word (DCOCW). The common capacitor node (X) is
also connected to the input of a Schmitt trigger (42)
that produces the output clock signal (OUTCLK) and a
feedback signal that is applied to logic (38, 39) that
inverts the common node of the capacitors (40). The
switching time at the input of Schmitt trigger (42)
depends upon the variable load presented by the array of
switched capacitors (40), which is controlled by the
digital control word (DCOCW). As a result, the clock
signal (OUTCLK) is digitally synthesized by a single
stage of the DCO (60). A digital phase-locked loop (PLL)
clock generator circuit (50) including a phase detector
(64), digital loop filter (62) in combination with the
DCO (60), and a programmable frequency divider (66)
providing a feedback path from the output of the DCO (60)
to the phase detector (64), is also disclosed. The PLL
clock generator (50) may be used in an integrated circuit
such as a digital signal processor (30) or
microprocessor, and is particularly well-suited for use
in a battery-powered portable electronic system (200).

IPC: G06Q10/00

Abstract: The present invention relates to the area of workflow
management systems (WFMS). WFMS execute a multitude of process
models consisting of a network of potentially distributed
activities. The current invention is dedicated to the
implementation of events within WFMS. The current invention
teaches to implement events like any other process activity. 
Thus events are implemented as event-activities, a special
type of an activity within said WFMS. Such an event-activity
can manage an event occurring internal or external to the
WFMS. 
This approach allows to make all features available to common
activities also accessible to event activities; examples are:
input-container and/or output-container, control-connectors,
data-connectors, notification-mechanisms, predicates
associated to control connectors forming transition conditions
and many more. A control connector leaving an event activity,
which optionally may be associated with a logical predicate as
outgoing transition condition, allows the WFMS to
automatically activate a target activity if said event
activity terminated after the event has been signaled to said
event activity and if the outgoing transition condition
evaluates to true. Similar an incoming control connector,
which optionally may be associated with a logical predicate as
incoming transition condition, allows a WFMS to automatically
activate an event activity if the process activity being the
source of said incoming control connector terminated and if
said incoming-transition-condition evaluates to true. 
This invention also teaches to extend the navigator of a WFMS
by an event management system which inter-operates with the
navigator to deliver above mentioned functionality. The event
management system encompasses the component of an event
monitor administering awaited events in a awaited event table
and further administering signaled events in a posted event
table. The event management system further encompasses the
component of an event manager maintaining information on
events allowing to verify correctness of an event.

Abstract: In a center, a Fourier transformation with a
weighting function and a center matrix are applied to the
identifier of each entity (steps 2-1, 2-2), which is then
randomized by one-time pass random number data generated by
a manual operation at each entity, thereby generating a secret
private key peculiar to each entity (steps 2-3 ~ 2-5)-
The center also generates an identifier transformation algorithm
based on the one-time pass random number data and the
Fourier transformation with a weighting function (step 2-6).
Thereafter, the center distributes the identifier transformation
algorithm and the secret private key to each entity.
Each entity applies the identifier transformation algorithm
and the secret private key to the identifier of another entity
with which to communicate, for thereby generating a
common cryptokey for cryptographic communications between
the entities. 
     Such a method of sharing a cryptokey can provide
increased security against various forms of attack while
simplifying the generation of the common cryptokey.

Abstract: In a method and apparatus for performing joint stereo coding of multichannel
audio signals (L,R) using intensity stereo coding techniques predictive
filtering techniques are applied to the spectral coefficient data, thereby preserving the
time structure of the output signal of each channel, while maintaining the benefit of
the high bit rate savings offered by intensity stereo coding. In one illustrative
embodiment of the invention, the input signal is decomposed into spectral
coefficients by a high-resolution filterbank/transform (12l, 12r); the time-dependent
masking threshold of the signal is estimated using a perceptual model (11l, 11r); a
filter (16l, 16r) performing linear prediction  in   frequency  is applied at the filterbank
outputs for each channel; intensity stereo coding techniques (in 13) are applied for
coding both residual signals into one carrier signal; the spectral values of the carrier
signal are quantized and coded (in 14) according to the precision corresponding to
the masking threshold estimate; and all relevant information ( i.e. , the coded spectral
values, intensity scaling data and prediction filter data for each channel, as well as
the additional side information) is packed into a bitstream (in 17) and transmitted to
the decoder.
