Abstract: ABSTRACT OF THE DISCLOSURE      A digital phase detector which periodically detects the phase angle .theta.k of a carrier signal in which data are en-coded as phase changes.  A coherent or differential phase-modulated carrier signal is split into its in-phase and quadrature phase components RoSin .theta.(t) and RoCos .theta.(t).  Each signal component is sampled at a predetermined modulation interval and converted into a digital word having the form RoCos .theta.k and RoSin .theta.k.  In one configuration, the two signal components are applied to a digital divider network which forms the quotient ? of the two digital words such that ¦?¦ ? 1.  The quotient ? is applied to a data look-up ROM, programmed for Tan-1 operation, which forms a digital reference phase angle .PHI. limited to an angle ? 45°.  Phase angle .PHI. is corrected by selection logic to form the desired phase angle .theta.k.  Once .theta.k is known for each modulation interval, the encoded data may be readily extracted, since .theta.k represents the encoded data.

Abstract: ABSTRACT OF THE DISCLOSURE   A control system for a microwave oven includes a programmable digital logic control circuit which enables a user to program information into the digital logic control circuit. The digital logic control circuit of the present invention allows a user to program information into the control, relating to the amount of time the magnetron tube is to be energized.  The control also allows the user to select the power level or duty factor at which the magnetron is energized from three different levels, thus providing a choice to the user as to whether the magnetron is to be operated in a defrost mode, a slow cook mode or a cook mode.  The control of the present invention allows the oven to be operated in a single stage manner whereby the microwave oven is operated in the defrost, slow cook or cook modes for the amount of time programmed into the control by the user.  Alternatively, the oven may be programmed in a two stage manner whereby the user determines the duration of the defrost portion and the duration of the cook portion in a combination defrost-hold-cook mode.  The user may also program the oven so that it operates in a combination defrost-hold-slow cook mode.  A time of day clock and a timer is also provided by the control of the present invention.  The user programs information into the control by means of a touch plate which is sectioned off into a plurality of areas, each area representing certain information to be entered into the control.  Information in the control such as the time of day, the time remaining in any of the microwave modes, the time remaining in the timer mode, or the information which has been entered by the user is displayed to provide a visual feedback to the user.

Title: System for measuring irradiation doses intended for use in radiotherapy apparatus
Inventor: AZAM GUY
IPC: H05G1/54
Filed: 1976-04-14
Granted: 1979-05-08
Abstract: ABSTRACT OF THE DISCLOSURE:         A system for measuring radiation doses in radiotherapy comprises two identical metering networks energized in parallel from a common radiation source, each network including an inte-grating amplifier whose time constant is variable by the short-circuiting of an input resistor.  A manually or automatically re-versible switch selectively foreshortens the time constant of one or the other amplifier whereby the corresponding metering network controls the cutoff of the radiation source whenever the emitted radiant energy reaches a predetermined value.  The other network, acting as a backup, takes over the radiation cutoff upon failure of the controlling network; this takeover may be indicated by a set of signal lamps jointly controlled by the reversing switch and by a counting unit of the standby network.
