摘要： A pass through oven system using a microwave oven with doors and a conveyor belt passing through the oven cavity. A sensor system detects the food item on the conveyor belt and identifies the food item. A controller in response to the sensor system moves the conveyor so that the food item is positioned within the cavity of the microwave oven, automatically engages the oven for a preset duration depending upon the identity of the food item and then moves the conveyor to remove the food item from the cavity.

摘要： A water level detection system and method for automatically controlling in real time the water height in a washing machine to assure the optimum operating level. An ultrasonic transceiver generates a plurality of ultrasonic pulses and detects the corresponding echoes. A microprocessor stores a plurality of ranging signals representing the time period between the ultrasonic pulse and the detection of the corresponding echo. A set of the ranging signals forms a mathematical or graphic signature which changes as the water level rises up through the clothes in the washing machine. The microprocessor detects when a predetermined characteristics occurs in this signature and sends a signal to the standard washing machine controls to stop the flow of water.

摘要： Method and apparatus for determining moisture content of materials by irradiating a sample of unknown moisture content with a narrow frequency band of light at a first wavelength during a first time period and a narrow frequency band of light of a second wavelength during a second time period. The two wavelengths of light have different water absorptive characteristics, and therefore are reflected by varying degrees depending on the surface moisture on the material. The respective reflections are measured by a single common detector, and a value corresponding to the ambient light is subtracted from each measurement. A ratio of the resultant values is then correlated with data derived from precalibration measurements of samples of known moisture content.

摘要： An oven with high power radiant cooking elements which are capable of operating at different intensities is disclosed for cooking food quickly with infrared radiation. The conduction of this infrared radiant energy varies substantially from food to food. Accordingly, the user of the oven must develop a unique data base or recipe for each food. A recipe consists of a number of stages each of which defines the output intensity of each cooking element for a period of time. A method is disclosed for the real time development of a recipe by varying the intensity of the cooking elements during the cooking cycle, optimizing the developed recipe to reduce the number of stages, storing the optimized recipe in memory and retrieving the optimized stored recipe for future use.

摘要： A moisture content measuring apparatus and method wherein a sensor station produces calibration data corresponding to measurements of light at two different wavelengths reflected from a material, and the calibration data is then transferred to a hand held computer. The moisture content of a sample of the material is measured and input to the hand held computer. The process is repeated after changing the wetness of the material, and the hand held computer creates a table correlating reflection data to moisture content. The table is transferred to the sensor station which then continuously generates signals representing moisture content in response to real time reflection data and the table. The cost effectiveness of the sensor stations readily facilitates the use of a dedicated sensor station at each of a plurality of conveyors carrying different materials to be combined into a composite of predetermined proportions by weight. Based on the real time moisture contents of each material, the respective flow rates are adjusted to compensate for moisture in order to produce the predetermined proportion.

摘要： An ultrasonic grade and auger control for use on a road paving machine to compensate for uneven road surfaces is described. As the road paving machine travels, asphalt is centrally deposited along the road bed. An auger is connected to the back of the road paving machine and contains a series of spiral blades which moves the asphalt away from the center of the road bed toward its outer edges. The ultrasonic auger control apparatus detects the height of the asphalt positioned at the outer edges of the paving machine and regulates the speed of the auger to provide even distribution of the asphalt. A screed is located behind the auger to uniformly place and pack the paving material. The ultrasonic grade control apparatus regulates hydraulic actuators which control the thickness of the new road surface by adjusting the height of the screed.

摘要： A coin diameter discriminating device wherein a coin is received in a coin transport mechanism which is rotated by a motor at an accurately controlled angular velocity. By such arrangement, the coin is carried along a predetermined path at an accurately controlled or regulated velocity past at least one optical sensor that provides a change of state output upon detecting an edge of the coin. The sensor is arranged to start a time counter that is stopped by a predetermined reference event such as the coin transport mechanism having rotated to a predetermined angular orientation. The time count in the counter therefore corresponds to the angular orientation of the coin transport mechanism at the time of detecting the coin edge, which also accurately corresponds to the diameter of the coin. The time count is then compared to corresponding time count ranges each of which relates to known standards of an acceptable coin denomination.
