Patent EP-0422398-A2 (EP)
Inventor: O'BRIEN JOHN KEVIN
IPC: G06F9/45
Filed: 1990-09-12
Abstract: Removal of invariant branches from nests of loops results in an optimized computer program with increased speed of execution. To accomplish this objective, each loop of a program is then examined, looking at inner loops before their containing outer loops, to locate conditional branch instructions which are loop invariant. Each conditional branch which is evaluated based upon loop invariant calculations is rewritten, outside the outermost loop for which this branch is invariant. The moved branch is modified to branch around the loop in which it was originally contained if its condition is evaluated false. A new copy of the loop is made in which the invariant branch is rewritten as an unconditional branch. In the original copy of the loop, the invariant branch is deleted, and a branch is inserted after the modified original loop to skip around the new copy when the original copy is executed. Finally, any sections of the program which will never be executed as a result of the above described transformation are deleted.

Abstract: A data acquisition system is described for converting a plurality of analog information signals to a corresponding plurality of digital output signals each (a) having a dynamic range of n bits to match the dynamic range of the corresponding analog information signal, and (b) representative of the corresponding analog information signal during each of a plurality of time intervals. The system simultaneously converts each of the analog signals to an intermediate digital signal during each of said time intervals in accordance with a digitization code of m bits (where m is less than n) such that the digitization intervals of the code increase non-linearly so that the ratio of the noise level of the intermediate digital signal and the digitization interval of the code is substantially constant throughout the dynamic range of said analog signals. The intermediate digital signals are transformed to the corresponding digital output signals.

Abstract: For pseudo-random noise (PN) code correlation, a GPS receiver employs sign and magnitude input weighting for each of the in-phase (I) and quadrature-phase (Q) samples of a received PN-code modulated carrier. A programmable R factor register (82) provides input A/D sample sign and magnitude weighting control by a multiplexer (84) of outside crossing samples for interference rejection of other RF signals interfering with the received PN-code modulated RF carrier. The R factor weighting determines whether the A/D samples (I out, Q out) are from a linear or adaptive A/D converter. In-phase reference (IREF) signals (CIX7:0) and quadrature-phase reference (QREF) signals (CQX7:0), produced by an internally generated PN-code reference system (48, 50, 52, 34, 36, Fig. 3), are provided to a plurality of I and Q multi-Y-tap correlator/integrators (88-102, 114-128 Fig. 9) for correlation with the I and Q samples. The apparatus correlates I and Q samples obtained from IF sampling or baseband sampling of the received PN-code modulated carrier.

Abstract: In conventional methods for coating opto-electronic components, particularly semiconductor lasers, the layer thickness of a layer to be applied is optically measured. The optical signal is converted into an electrical signal in a photodiode, and this signal is used for controlling the coating.

From the noise power, a control computer (10) obtains a signal for controlling the layer thickness; this is supplied to a coating arrangement (14) of a coating reactor (2) which has a reaction chamber (1) in which the component (3) to be coated is located.

Abstract: A method of separating an aqueous colloidal solution by agglomeration into water and agglomerate of colloidal particles by applying voltage to the aqueous colloidal solution to promote the agglomeration of colloidal particles. The frequency of the voltage to be applied to the aqueous colloidal solution is increased to about 10kHz to improve efficiency of agglomeration and suppress electrolysis of water. As the frequency is increased, hydrogen is generated earlier than the reaction of oxygen generated by the electrolysis of water with the colloidal particles, thus not oxidizing the colloidal particles. Further, as the frequency is increased, the colloidal particles tend to obtain a greater oscillation energy, thus facilitating the agglomeration thereof.
