Patent EP-0365819-A2 (EP)
Inventor: SMITH THOMAS BASIL
IPC: G06F11/18
Filed: 1989-09-16
Abstract: A system for providing fault-tolerant synchronized operation of the Time of Day (TOD) clocks of the respective data processors in a multiprocessor complex. Basically, the system is comprised of a duplex implementation having redundant TOD clock sources, and a plurality of TOD slaves which provide the TOD clocks in the associated processors. A register/counter in each TOD clock source is incremented by a high frequency signal to achieve the required TOD value resolution, and the latter signal is divided down to provide a lower reference frequency signal for synchronization of the clock sources. Each TOD slave includes means for receiving a pair of reference frequency signals and for trouble-free switching between the signals, as required. Alternately, a quad implementation of clock sources which is substantially free of single points of failure of the synchronization mechanism is described. Frequency steering of the clock sources provides increased accuracy and conformity to real time when desired.

Abstract: This invention relates to a process for the separation of acrylonitrile used in the cyanoethylation of glycols to produce a bis(cyanoethylated) aliphatic glycol from the resulting glycol which is then reduced with hydrogen to produce the corresponding bis(aminopropyl) alkoxy glycol. In this process, acrylonitrile or methacrylonitrile is reacted with an aliphatic glycol in stoichiometric excess and the acrylonitrile removed from the cyanoethylated glycol by reaction with aliphatic primary or secondary alcohol prior to effecting the hydrogenation of the cyanoethylated aliphatic glycol in the presence of the acrylonitrile-amine reaction product. The reaction product then can be separated by conventional techniques such as distillation.

Abstract: An operand processing unit delivers a specified address and at least one read/write signal in response to an instruction being a source or destination operand, and delivers the source operand to an execution unit in response to completion of the preprocessing. The execution unit receives the source operand, executes it and delivers the resultant data to memory. A "write queue" receives the write addresses of the destination operands from the operand processing unit, stores the write addresses, and delivers the stored preselected addresses to memory in response to receiving the resultant data corresponding to the preselected address. The addresses of the source operand is compared to the write addresses stored in the write queue, and the operand processing unit is stalled whenever at least one of the write addresses in the write queue is equivalent to the read address. Therefore, fetching of the operand is delayed until the corresponding resultant data has been delivered by the execution unit.

Abstract: A vehicle near-obstacle detector in the form of a diplex Doppler radar apparatus provides range information between a vehicle and an obstacle based on the phase shift between a pair of Doppler signals (D1,D2) derived from two transmitted radar signals at slightly different frequencies. A speed dependent error introduced by the time constant of a filter circuit (54) converting duty cycle range information based on the phase shift to an analogue signal is compensated by introducing a small time shift (35) in the signal path of one of the Doppler signals to effect a shift in the duty cycle range information.

Abstract: A novel optical system is taught including an optical source, an optical modulator (128) having at least one optical input port for receiving the optical signal from the optical source, a modulation port for receiving the optical signal from the optical source, a modulation port for receiving a modulating signal, and complementary output port signals (132). The complementary modulated output signals are applied to one or more optical receivers at the other end of an optical transmission link. In one embodiment, the two complementary signals are provided to two separate optical receivers, thereby allowing distribution of optically modulated signals, for example, in a cable television or other type distribution system. In another embodiment, the two complementary modulated signals are applied to a single balanced receiver, thereby providing information content to the complementary receiver twice the power level available on either one channel alone. Furthermore, utilizing a balanced receiver, common mode error signals cancel, thereby increasing the signal to noise ratio of the system. In one embodiment of this invention, a single optical transmission channel is used, and the two optically modulated signals are separated in polarization (132) so as to be capable of being separately detected on the receiving end of the link. In one embodiment feedback means is used to insure proper polarization states for the two complementary signals.

Abstract: A method for determining the adequacy of a cervical or urethral test specimen collected for a chemical assay to detect the presence of  Chlamydia trachomatis . Cells present in the specimen are disrupted to expose a substance present in or on  C. trachomatis  that is detectable by chemical reaction. In order to determine if the test specimen contains an adequate amount of the cervical or urethral cell type that serves as the host cell for  C. trachomatis , the disrupted specimen is also reacted with a chemical reagent that produces a detectable response upon reaction with a substance present in or on columnar epithelial cells. The present invention therefore provides a control reaction that verifies the adequacy of the collected test specimen and thereby increases the confidence that a negative test result for the presence of Chlamydia indicates the absence of a  C. trachomatis  infection in the patient.

Abstract: This invention relates to thermal printing, and, in particular, to a coating for preventing sticking of thermal printing materials to a thermal printhead of a thermal printer. In one form of direct thermal printing, colorless forms of heat-activatable dyes are incorporated into a polymeric binder borne on a suitable carrier. Upon application of heat in an imagewide manner, these dyes are converted to their colored forms to form an image in the dye-containing material. Because commonly used polymeric binders are thermoplastic, there is a tendency for them to soften in the heated areas and stick to the thermal printhead, thereby causing malfunctioning of the printing apparatus and reduction in image quality. In thermal transfer printing, the printing process occurs by heat-activated transfer of image-forming material from a donor to a receptor such that the receptor bears the formed image. The construction of the donor requires that the image-forming material be carried upon a thin, flexible backing. The image-forming material may take several forms, such as, for example, a meltable colored wax. Many of the most suitable backing materials are thermoplastic, and therefore have a tendency to soften and stick to the printhead during the thermal imaging process, thereby causing poor print quality and malfunctioning of the printing machine. This invention provides a layer for preventing sticking of thermal image-forming materials to thermal printheads during thermal printing. The layer comprises polymeric material having a non-cyclic, substantially completely saturated hydrocarbon backbone, said backbone having substantially only hydrogen atoms and methyl groups attached to randomly positioned carbon atoms thereon, with no more than one methyl group attached to any one backbone carbon atom. Solubility of the polymeric material in commonly used organic solvents allows very thin layers of the coating to be applied in the form of dilute solutions.

Abstract: A linear motor comprises a stator 1 and an armature 2 provided, respectively, with a set of spaced apart permanent magnets and a set of drive coils (not shown). The permanent magnets produce a radial magnetic field whose strength varies periodically along the length of the stator 1. The field strength is to derive speed and position signals by means of detectors constituted by field coils 4 and Hall Effect sensors 10. The periodic variation of the field strength is compensated for in the case of the field coils 4 by staggering their phases along the length of the armature and selectively combining their outputs; in the case of the Hall Effect sensors, the periodical variation is used to derive positional information.
