IPC: G05B19/04

Abstract: Method and apparatus providing a programmable logic device which has a high level subroutine stack element and a random access memory suitable for control applications. The method utilizes high level constructs bearing a one-to-one relationship to the architecture of the apparatus so that the design of the controller is facilitated resulting in a rapidly-executed program which is easy to comprehend, verify and document. Subroutines are readily implemented by the controller by virtue of its last-in, first-out stack and a state counter which allow the contents of the counter to be "pushed" onto the stack upon invocation of the subroutine and "popped" from the stack upon return from the subroutine. Provision of the random access memory allows the controller to store information supplied from an external device, such as a central processing unit. The operation of the controller can be readily modified according to the control information stored in the memory by use of a high level language RAMREAD construct. The random access memory also provides scratch pad capability for the controller so that information written to a memory location, under control of a programmable OR array, can be used as a separate, independent counting and timing channel, in an exemplary application. The stack and/or the random access memory are suitable for inclusion in a controller of either a programmable logic array (PLA-), programmable array logic (PAL-), or a programmable read-only-memory (PROM-) based design.

Abstract: This invention relates to tape, in particular, tape reinforced by means of filaments. 
     Individual optical fibers of fiber optic cable are generally bound by tapes or yarns. Yarns currently used in binding bundles of optical fibers frequently attenuate the optical signal by placing high stress at various points on individual optical fibers. 
     This invention provides a tape reinforced by means of filaments comprising a backing and a plurality of yarns comprising a multiplicity of filaments adhered to at least one major surface of said backing by means of a layer of an adhesive. The yarns are disposed essentially parallel to each other along the machine direction of the tape. The yarn-bearing surface of the backing is coated with a polymeric material that both overcoats the filaments and detackifies the residual adhesive between the yarns. The yarns are preferably elliptical in cross-section, with the major axis thereof being essentially parallel to the plane of said backing. In a second embodiment, the tape is reinforced by individual filaments adhered to the backing by means of a layer of adhesive. 
     One advantage of the tape of this invention is that it provides much less localized stress on optical fibers than does yarn typically used to bind optical fibers.

Abstract: The method serves to grind cams (10) of a camshaft. The cams (10) are rotated at a predetermined angular velocity ( omega ) about a first axis (13) running through the centre of a base circle (15) of the cams (10). A grinding wheel (20) bears with a generating line (23) parallel to the first axis (13) against the cams (10). It is moved as a function of the rotary position ( phi ) of the cams (10) relative to the first axis (13) along a second axis (11) which is perpendicular to the first axis (13). This takes place in such a way that the generating line (23) travels on a predetermined cam contour (15, 16, 17) during the rotation of the cams (10), the angular velocity ( omega ) being varied during the rotation of the cams (10). In this way, the generating line (23) travels along the base circle (15) at higher angular velocity ( omega G), whereas it travels along flanks (16) and a tip (17) of the cams (10) at reduced angular velocity ( omega F). In order to reduce the remaining cam form errors without increasing the total grinding time, the angular velocity ( omega ) in the area of the tip (17) is set at a value ( omega S) above the reduced angular velocity ( omega F) but below the higher angular velocity ( omega G). <IMAGE>

Abstract: The invention relates to the direct detection of human papillomavirus DNA. The recently developed polymerase chain reaction has been modified in order to improve sensitivity and specificity. It is possible, by choosing suitable oligonucleotide primers (amplimers) and reaction temperatures, for individual HPV genes to be identified among the total cell 4 DNA and amplified to such an extent that non-isotopic detection is possible. In addition, the use of reverse transcription allows deliberate amplification of spliced mRNA and thus an indication of premalignant or malignant states or lesions.

Abstract: In an encoder device for encoding a sequence of digital speech signals classified into a voiced sound and an unvoiced sound into a sequence of output signals, by the use of a spectrum parameter and pitch parameters, at every frame having N samples where N represents an integer, a judging circuit judges whether the digital speech signals are classified into the voiced sound or the unvoiced sound to produce a judged signal representative of a result of judging. A processing unit processes the digital speech signals in accordance with the judged signal to selectively produce a first set of primary sound source signals and a secondary sound source signals. The first set of primary sound source signals are produced when the judged signal represents the voiced sound and are representative of locations and amplitudes of a first set of excitation multipulses calculated at every frame. The second set of secondary sound source signals are produced when the judged signal represents the unvoiced sound and are representative of the amplitudes of a second set of excitation multipulses each of which is located at intervals of a preselected number of the samples.
