Abstract: The contents of totes and the amount a tote container is filled are monitored. A central database stores product dimensions and tote dimensions as well as a percentage of which a tote is to be filled. Image scanners that obtain three-dimensional images are used to determine if the actual dimensions of the tote, the product, and the fill amount are consistent with the expected or optimal values of these characteristics. When there is a discrepancy between measured and expected values, then one or more actions can be taken.

Abstract: A mobile cart that holds a bag for receiving solid waste generated during a medical or surgical procedure. The cart includes a sensor that monitors whether or not an object containing metal is placed in the bag. A processor monitors the signal output by the sensor. If the sensor signal indicates that an object with a minimal amount of metal is placed in the bag, the processor momentarily asserts an audible alarm and continuously asserts a light alarm. The light alarm remains asserted until turned off. If, while the light alarm is on, the sensor signal indicates a second object with the minimal amount of waste is placed in the container, the processor again momentarily asserts the audible alarm. This provides notice that it may be necessary to investigate the contents of the bag to determine if not one but two or more objects were inadvertently discarded.

Abstract: A system for detecting disposal of metallic objects into an opening of a medical waste container, including: an indicator for indicating passage of metallic objects through the opening, a pair of receive coils and a transmit coil spaced therebetween shaped for receiving waste therethrough adjacent to the opening, and a controller in electrical communication with the coils. The controller generates and communicates a transmit signal to the transmit coil, which generates a magnetic field that induces voltage in each of the receive coils, which each generate a receive signal. The controller generates a waveform based on the receive signals with a baseline corresponding to absence of metallic objects, and analyzes the waveform with respect to opposite first and second thresholds. The controller activates the indicator in response to metallic objects passing through the coils when the waveform first exceeds the first threshold and then subsequently exceeds the second threshold.

Abstract: A control apparatus for processing the electrical signals generated by an optical ratiometric color sorting scanner, said apparatus generating signals to cause the rejection of articles which differ in color and/or size from predetermined limits. In the scanner, two electrical signals are generated which are responsive to two different spectral regions or pass bands of the radiant energy reflected by the product being sorted. These signals are superimposed on a slowly varying signal responsive to the standing background light. The control circuitry processes the signals to delete the standing light signal and spurious noise signals and determines if the ratio between the signals is greater than or less than a predetermined value, or alternatively, determines when the ratio between the signals is not within a predetermined acceptable range and generates a delayed reject signal thereafter. Other circuits provide signals to a meter for displaying the present reject rate and particle feed rate.

The output of the center sensor serves as a reference for the top and bottom sensors and a signal processing circuit connected with the sensors produces a suspect signal, indicating the suspected presence of a document in an envelope, when the output of either the top or bottom sensor compares unfavorably with that of the center sensor for an amount of time sufficient to make the device insensitive to short duration opacity differences caused by overlapping envelope seams.
