摘要： A microwave oven includes a microwave source and a defrost detector arranged in the oven cavity in the proximity of a frozen product to be processed, the absorption of microwave energy being distributed between the detector and the product and causing their temperature to rise, the temperature variation of the detector being measured by a measuring element producing a corresponding electrical signal. The oven also includes a computing control device which determines completion of defrosting of the product by computing the values at successive instants of the second derivative of such signal as a function of time. The computing control device controls the oven at the end of the defrosting cycle, which is when the value of such second derivative falls below a predetermined value.

摘要： A device for contolling the charging of rechargeable batteries comprises two temperature sensors deposited on a flexible thin thermally and electrically insulating sheet. The thin sheet is disposed around the rechargeable battery so that one of the sensors determines the temperature of the battery and the other sensor determines the ambient temperature. A charge stopping device stops the charging of the battery when the difference between the temperatures determined by the two sensors has reached a predetermined value. The sensors consist of resistors applied by silk screen printing and disposed in a Wheatstone bridge arrangement.

摘要： A microwave oven which provides defrosting control for a frozen product to be defrosted. The oven comprises a microwave source and a detector arranged in the oven cavity in the proximity of the frozen product, the detector including a material which absorbs microwave energy, the absorption of microwave energy by the detector and by the frozen product causing their temperatures to rise and thereby defrosting such product. Variations in the detector temperature are measured by a measuring element which provides an electrical signal corresponding thereto. The detector is configured and insulated so as to have a heat exchange characteristic with its environment which results in its temperature detection sensitivity remaining constant during each of a plurality of successive defrosting operations of the oven. A computer control device evaluates when a defrosting operation has been completed by determining when the slope of the signal variation as a function of time remains the same at successive sampling instants.

摘要： A microwave oven which includes a defrosting detector in the oven cavity in the proximity of a frozen product to be defrosted, the detector including a material which absorbs microwave energy, the absorption of microwave energy by the detector and by the product causing their temperatures to rise. Variations in the detector temperature are measured by a measuring element producing an electrical signal corresponding thereto, such signal being used to control the defrosting process. The microwave absorbent material is in the form of a layer deposited on a carrier which is positioned behind the product so that most of the detector area can only receive microwave energy through the product, whereby the rate of change of detector temperature with time decreases as the product defrosts and becomes constant when defrosting has been completed. The carrier may be one of the walls of the oven cavity or the oven tray. The material may be a resistive ink deposited on the oven tray by screen-process printing.

摘要： A microwave oven with a door-closing safety device is provided wherein a movable door comprises a device wherein the beam of at least one light emitter is guided by means of light guides towards a light beam detector. The light guides are arranged along a substantial portion of at least one side of the oven door frame. The beam of light in its non-guided path between the emitter and the detector passes through diaphragms, integral with the oven door, each diaphragm having an aperture such that the light beam passes through it when the door is properly closed but wherein the light beam is intercepted by the edge of the diaphragm when the door is not properly closed. The detector activates a signal that actuates the magnetron when the light beam is received; however, when the beam is intercepted, activation of the magnetron is prevented thereby preventing leakage of microwave energy.

摘要： A cook-top (10) includes a plurality of heating elements (11a, 12a) which are activated by function controls. The heating elements are covered by a plate (15) which are fixedly connected to strain-guage modules (30) which detect the forces exerted on the plate as a result of loads placed on the heating elements. By computing the center of gravity of the forces, controls (70, 75, 76) identify a heating element whose load has varied and influence its electric power supply. The power supply may then be turned off, reduced or controlled. The function controls may be pressure-sensitive touch controls.

摘要： The invention proposes a mechanism for retransmitting packets which comprises a step for checking at the transmitter whether the retransmitted packet will be received by the receiver in time to be processed. To this end, the receiver sends in its retransmission request the processing time indication of the packet being processed at the receiver when the request is transmitted. At the transmitter end, this processing time indication is compared with the processing time indication of the packet to be retransmitted so as to authorize or block its retransmission.
