IPC: H04L27/38

Abstract: In a quadrature demodulation circuit, when the number of the
errors detected by an error detecting/correcting circuit is larger than a
predetermined value, a selector supplies a digital in-phase signal and a
digital quadrature signal outputted from A/D converters located before a
waveform equalizer, to a carrier phase error detecting circuit which
generates a digital phase error signal fed back through a D/A converter to
a local carrier oscillator. When the number of the errors detected by the
error detecting/correcting circuit is not larger than the predetermined
value, the selector supplies a digital in-phase demodulated signal and a
digital quadrature demodulated signal outputted from the waveform
equalizer, to the carrier phase error detecting circuit. 
     Thus, when a large frequency variation is detected, the carrier
reproduction is conducted by using the carrier reproduction loop having a
signal distortion but a small delay, and then, if the reproduced carrier
becomes stable at some degree, the carrier reproduction is conducted by
using the carrier reproduction loop having a less signal distortion but a
large delay.

Abstract: A method and a system for detecting a user signal in a CDMA network.
(Coded) user message bits are grouped into successive groups. A differential phase is
generated for each message bit group by mapping each message bit group on to a
predetermined PSK constellation. An absolute phase is generated for each message bit
group based on the differential phase for the current message bit group and the absolute
phase for the preceding message bit group. The absolute phase signal is phase keyed to an
RF carrier to form an RF signal. The RF signal is spread using two code sequences and the
spread RF signal is transmitted. At the receiver, the RF signal is received and non-coherently
demodulated. The demodulated RF signal is despread using the code
sequences. Successive blocks of the demodulated, despread RF signal are phase compared
for extracting the differential phase signal carrying the (coded) user message.

Abstract: The memory control this invention includes a microprogram-read-only-memory
(CROM) containing micro-instructions for
operation of an integrated-circuit memory, a program counter
multiplexer (PCM) to select instructions from the control-read-only-memory,
a micro-instruction decoder with BILBO control
(MID/BC), a test input multiplexer (TIM) to test control
signals, an optional status output register (SOR) to generate
control signals, and a subroutine stack (SS) to allow function
calls. A program counter (PC) takes an index signal from the
micro-instruction decoder with BILBO control (MID/BC) and a
signal from the program counter multiplexer (PCM), and from
those signals, generates a next microcode address. Complex
program, erase, and compaction instructions for the integrated-circuit
memory are implemented using a relatively small number
of control-read-only-memory locations and using a relatively
small surface area on the memory chip. Control instructions are
easily modified to compensate for process and structure

integrated-circuit memory.

Abstract: A system for allowing a two word instruction to be executed in a
single cycle thereby allowing a processor system to increase memory
space without reducing performance. A first address bus is coupled
to the linearized program memory for sending addresses of
instructions to be fetched to a linearized program memory. A
pointer is coupled to the first address bus for storing an address
location of a current instruction in the linearized program memory
to be fetched and for placing the address location of the current
instruction to be fetched on the first address bus. A second
address bus is provided and has one end coupled to the output of
the program memory and a second end coupled to the first address
bus. The second address bus is used for placing an address of an
operand of a second word of the two word instruction onto the first
address bus after an address of an operand of a first word of the
two word instruction has been placed on the first address bus.
This allows the addresses of the first word and the second word to
be combined to provide the full address value of the two word
instruction in a single cycle.

Abstract: The image rendering system (20) of the present invention rapidly renders
graphical image of complex structures. A complex structure is represented by a
plurality of objects that can be organized into an object hierarchy. The image
rendering system (20) projects a plurality of rays (55) from a given vision coordinate.
For each projected ray, the image rendering system (20) determines with which
objects in the object hierarchy are intersected by the ray (55). The image rendering
system (20) then determines which object among those intersected by the ray (55) is
closest to the given vision coordinate and adds that object to a set of visible objects.
As objects are added to the set of visible objects, each object is rendered on the
display in accordance with a current vision coordinate. Since the process of adding
objects to the set of visible objects is decoupled and run asynchronously from the
process of rendering visible objects on the display, the image rendering system (20)
is capable of rendering objects at real-time frame rates.

Abstract: The system includes a major tank (111) containing liquid material for dipping
an article (W) thereinto; and a circulatory mechanism (P11,P12) for circulating the
liquid material through the major tank (111). The circulatory mechanism is arranged to
cause a flow of the liquid material through the major tank (111) such that the majority
of the flow is in one direction that is substantially along the longitudinal direction of the
major tank. Thus, contaminants and/or bubbles are not distributed over the entire major
tank, but are effectively promptly removed from the major tank. The flow of the liquid
material may include a first flow and a second flow that is lower than the first flow.
The first and second flows run substantially in parallel with each other, before they
reach the downstream end in the major tank. The major tank may be formed at the
downstream end with a wall having a special configuration such that the first and
second flows separate or diverge from each other at the downstream end, and thus the
flow of the liquid material through the major tank becomes very smooth.
