Abstract: MICROWAVE OVEN CAVITY EXCITATION SYSTEM PROVIDING CONTROLLED  ELECTRIC FIELD SHAPE FOR UNIFORMITY OF ENERGY DISTRIBUTION        ABSTRACT OF THE DISCLOSURE           A microwave oven cavity excitation system for promoting time-averaged uniformity of microwave energy distribution within the cooking cavity.  Circularly-polarized microwave energy is radiated from a feed waveguide into an adjacent cooking cavity by means of an aperture, such as an X-slot, in the feed waveguide properly electrically located laterally within the feed waveguide so as to nominally radiate an electric field having circular polarization properties and, overall, shaped as an approximate hemisphere.  A cross-sectional slice of the field, for example in the plane of the food supported on a conventionally-located shelf, is circular in shape.  The radiating X-slot is control-lably and selectively electrically moved laterally with respect to the waveguide centerline with the result that the sectional shape of the resulting field changes from circular to elliptical, with the degree and orient-ation of the ellipse depending upon the direction and degree of movement of the coupling aperture with res-pect to the waveguide centerline.  The shape of the field is constantly varied through various elliptical configurations during operation, to provide the desired time-averaged uniformity of energy distribution through a suitably-programmed controller.

Title: Linearizing system for dual slope analog-to-digital  converter

Granted: 1983-08-02
Abstract: Abstract of the Disclosure A system for linearization of the digital output of a dual slope analog-to-digital converter.  An analog signal representing the measured output of a condition responsive transducer is supplied to the dual slope integrating analog-to-digital converter also receiving a regulated constant reference signal.  Using the integrator in a non-inverting mode, the A/D converter operates in a single conversion cycle by first positively integrating a value of the received analog signal below a maximum negative input voltage for a fixed time period and then negatively integrating a voltage signal corresponding to the differential between the reference voltage signal and the maximum voltage signal for a variable time period to a comparative threshold.  During integration, digital counts proportional to the variable integration period are accumulated and emitted for operating a digital device such as a digital display.  Digital linearization of the converter output is provided by use of a programmed microcomputer reading a programmable-read-only-memory (PROM) to run a variable frequency clock.  The clock is regulated to effect a first phase converter time corresponding with an even multiple of the power line frequency.
