  • Patent number: 4852050
    Abstract: A signal processing method in autoradiography for determination of the base sequence of DNA or a DNA fragment, employing groups of radioactively labeled base specific cleavage products or mixtures thereof obtained by specifically cleaving the DNA or DNA fragment labeled with a radioactive element and resolved one-dimensionally in parallel relation to each other to form resolved rows on a support medium. An autograph is obtained having locational information on groups of radioactively labeled cleavage products contained in the rows on the support medium. An electrical digital signal corresponding to the autoradiograph is then generated by recording and reproducing from a stimulable phosphor sheet the radiation energy stored therein. Sampling points in each resolved row of the digital signal are next detected. Reference sampling points are then determined in a plurality of reference rows which are either directly provided on the support medium and/or synthesized from certain resolved rows.

  • Patent number: 4849925
    Abstract: Disclosed are two modifications of the Tank-Hopfield circuit, each of which enables the deconvolution of a signal in the presence of noise. In each embodiment, the Tank-Hopfield circuit is modified so that the equation for total circuit energy reduces to one term representing convolution and another information theoretic (or Shannon) entropy. Thus, in finding its global minimum energy state, each modified circuit inherently identifies an optimal estimate of a deconvoluted input signal without noise.

  • Patent number: 4841470
    Abstract: A differential phase shift keying convolver having a plurality of tracks includes at least one track where an opposite phase convolution output is produced. Each track includes two output gates spaced at the center for differential phase shift keying demodulation. Among these output gates, some gates selected in accordance with the phase relationship between convolution outputs are connected to provide sum and/or difference outputs of the convolution signals. The opposite phase convolution outputs can be produced by arranging at least one of the input transducers in a step-like configuration, by using multistrip couplers, or by providing a metal film in a selected position of the traveling path of surface acoustic waves for application of a control voltage.

  • Patent number: 4841441
    Abstract: An expert system uses internal rules for sound software development and in the end automatically produces a correct running system, without the need for the designer to work out the solution first or to enter any more than the facts (data types and procedure types) of the organization. To operate the user merely inputs data about the organization in response to prompts in the form of conversational language questions. The rest of the development of the software for that organization is actually done by the expert system itself.

  • Patent number: 4839805
    Abstract: Dual control of image level and window of a display is accomplished by rotation of a single trackball. Rotation of the trackball within a first band including the X axis controls one parameter, and rotation of the trackball in a second band including the Y axis controls a second parameter. No changes are made in the parameters in response to rotation of the trackball in a third deadband laying between the first band and second band. The operator of a tomography system can readily change display parameters by rotation of the trackball while viewing the display.

  • Patent number: 4837686
    Abstract: A system and method is disclosed for utilizing image pixel value information generated by a digital radiographic system for quantifying the amount of calcium in a particular object of interest within a subject, wherein the subject also contains additional quantities of calcium located at positions such that the additional calcium interfers with the acquisition of data describing the object of interest. A cursor configured as a parallelogram is described and pixel values are summed along lines parallel to the sides of the parallelogram. A profile is generated from these summations. A portion of the profile corresponding to pixel lines not intersecting the object of interest is used to estimate the contribution of background and other calcium to the profile as a whole, and this estimated value is subtracted from the total profile. Integration of the remainder of the profile provides a scalar value corresponding to the amount of calcium in the object of interest.

  • Patent number: 4833637
    Abstract: Acousto-optic multi-channel space integrating correlators and methods of using the same are disclosed. The correlators consist of a single channel acousto-optic cell illuminated by a light source, with the light from the cell imaged onto a second acousto-optic cell, typically a multi-channel cell, with the light between the two cells being single sideband filtered so as to pass only the desired components. The light from each channel of the second acousto-optic cell is directed to a respective light detector, or utilizing a segmented lens system, is split so that different portions of the light from each channel are directed to a different respective light detector.

  • Patent number: 4833636
    Abstract: A correlator, such as may be used in a phase detecting device of an automatic focusing circuit for a camera , has a simple arrangement that attains improved accuracy and high speed. A pair of charge storing elements is provided to which input signals are applied. When predetermined charges are supplied into potential wells formed in the charge storing elements, charge remaining in the potential wells depending on their depth can be detected as the absolute value of the difference between the two input signals. Therefore, the input signals can be subjected to correlation directly as they are, that is, in analog form, without conversion to digital form.

  • Patent number: 4829459
    Abstract: A programmable voltage offset circuit (PVOC) (1) comprises a temporary latch memory (7); a latch disable circuit (5) which selects that PVOC (1) among several such circuits which may be simultaneously present on the same semiconductor chip; a resistor array (3); and a programmable nonvolatile memory (37). The desired voltage offsets V(OFFSET)s are temporarily produced in an iterative manner using the latch memory (7). Quasi-permanent voltage offsets V(OFFSET)s are then programmed using the nonvolatile memories (37), each of which typically comprises an EPROM (39). Application of an avalanche voltage V(STORE) to a PFET (43) portion of the EPROM (39) causes the PFET (43) to avalanche, thereby selectively programming the nonvolatile memory (37), depending upon the status of a signal supplied from the latch memory (7).

  • Patent number: 4819162
    Abstract: The computerized time clock system includes a personal computer via which employee, job and schedule records may be assembled and maintained. A computerized time clock communicates with the personal computer and received employee and scheduling data therefrom, in order to validate and record time-in and time-out transactions executed by employees. Current time records are maintained in the memory of the time clock and at the end of each day are transmitted to the personal computer for addition to permanent disk records including a record of each time-in and time-out transaction for an extended period. Sales records may also be maintained in personal computer 20, for example the quantity of liquor or food served by a particular employee or in a particular department, which sales information may be correlated with labor costs found in the permanent time records.

  • Patent number: 4812976
    Abstract: A method and an apparatus are disclosed for characterizing the unknown state of a physical system having a variant signature, the characterization being made with reference to a known state of like physical systems. A response signature representative of the unknown system state is compared to a standard signature representative of the known system state. The standard signature comprises a multi-dimensional region within a pre-defined, transformed coordinate system having an inner and outer boundary. If the response signature lies wholly within the bounded region, the system being characterized is deemed to be in the known state. Conversely, if the response signature does not lie wholly within the bounded region, the system being characterized is deemed to be in a state other than the known state.
