Abstract: A matrix-based pattern prediction system of the present disclosure is that of a multi-block matrix-based system that operates on an input signal having a time-based pattern that is semi-chaotic. The system includes a wavelet/time conversion block M?, which is representative of a wavelet transformation of a semi-chaotic input signal, and a memory block MP which stores the wavelet coefficients generated by M? in an asymmetric matrix. The system further includes a predictor block MPP, which performs a time shifted symbolic operation on the memory block MP and is, therefore representative of the time shifted wavelet (M?). A Pattern Output block transforms the output predictor block MPP into a time-based output that is predictive of the semi-chaotic time-based input at a future point in time. First and second variables (Cp and Cpp) are automatically generated and used to compensate low (Cp) and high (Cpp) frequency components of an input.

Abstract: The Sewer Back-flow Preventer Monitor is a device designed to be an add-on to a sewer back-flow preventer valve, otherwise known as a backwater valve. It offers a higher level of protection against flood than that which is offered by a sewer backwater valve without any such device. It uses digital and/or analog electrical sensors, magnetically linked to the flapper, to determine the precise flapper position of a backwater valve and will warn a user of a municipal sewer backup and or back-flow. As well, it will provide an alert when a cleaning is necessary and informs users when a sewer backwater valve has successfully closed during an event. It is a cost effective solution.

Abstract: A load dump protection circuit includes a switch, a clamp circuit and a comparator. The clamp circuit is coupled between a power supply line and a first output terminal of the switch. A second output terminal of the switch is coupled to a common return. An output of the comparator is coupled to a control terminal of the switch. A first input of the comparator monitors a magnitude of a trigger signal on the power supply line. The switch provides a low impedance path between the first and second output terminals, when a magnitude of the trigger signal increases above a magnitude of a reference signal on a second input of the comparator. The switch provides a high impedance path between the first and second output terminals, when the magnitude of the trigger signal decreases below a shut-off level that is less than the reference signal.

Abstract: A protection circuit for protecting a switch from a fault includes a first sensing circuit and a second sensing circuit. The first sensing circuit senses a low-side load current through a switch that includes a first terminal, a second terminal and a control terminal. The first terminal is connected to a low-side of the load and the second terminal is connected to ground. The switch provides a conductive path between the first and second terminals responsive to a control signal provided on the control terminal. The first sensing circuit acts to reduce a magnitude of the control signal to limit the low-side load current, carried by the switch, when the low-side load current exceeds a first predetermined value. The second sensing circuit senses a voltage at the low-side of the load and interrupts the low-side load current, when the voltage at the low-side of the load exceeds a second predetermined value.

Abstract: A generic, self-tuning control system deployable in a wide variety of systems is achieved from a digital system effectuating a matrix chain. Each matrix in the chain yields an output based upon two or more inputs. The outputs of the various matrices making up the chain are used as inputs to other matrices in the chain. Measured inputs are state variables of the system under control. Some inputs that are generated by other matrices are state variables. Consequently, the set of values generated by the matrices results from the state variables describing the system at a given point in time. Initially, the matrices exhibit a quality referred to as symmetry. This quality serves to cause the system under control to transition to desired state. In addition to the controlling force exerted by virtue of the symmetry of the matrices, a learning algorithm may be introduced to the matrix chain.
