Abstract: A system and method of simulating and optimizing industrial and other processes includes a computer that performs multivariate analysis of input variables and output variables to generate a data model of the operation of the process. For industrial applications, the input variables include process variables and the output variables include result variables from the operation of the industrial process. The data model determines contributions to changes in the output or result variables by the respective input or process variables and is provided to a predictive algorithm to identify parameter values for input or process variables expected to have a most significant impact on the output or result variables during performance of the process. The outputs of the predictive algorithm are parameter values that are provided as input or process variables to the industrial process for simulation or performance optimization or product recommendations/optimizations.

Abstract: A facemask assembly for a self-contained breathing apparatus includes a facemask configured to be worn by a user, an electronic device connected with the facemask, a microcontroller configured to send signals to the electronic device, an accelerometer coupled with the microcontroller and configured to sense motion of the facemask; and a battery configured to supply power to the electronic device. When motion is detected by the accelerometer, a signal is transmitted to the microcontroller and the microcontroller interprets the electrical signal to selectively adjust the power level supplied to the electronic device.

Abstract: A system includes processing circuitry and a drone that includes a marking mount that receives a marking device, a motion guide that provides a sliding framework for a reciprocating motion of the marking mount, and a shock absorption sub-assembly positioned between the marking mount and the motion guide. Control logic of the drone is configured to navigate, based on navigation instructions received from the processing circuitry, the drone to an area associated with a misapplication of a tape as applied to a substrate or a substrate defect, such that a distal tip of the marking device makes contact with the area associated with the tape misapplication or the substrate defect, while activating the shock absorption sub-assembly to at least partially absorb a shock caused by the contact between the distal tip of the marking device and the area associated with the tape misapplication or the substrate defect.

Abstract: A system which is composed of a blower unit for a powered air purifying respirator and an electrically powered accessory. The blower unit has a blower device and a battery for powering the blower device. And the accessory is equipped with a power connector. The blower unit provides a power outlet for connection with the power connector. The power connector has a plug. Furthermore the power connector has an unplug lever for retracting the plug for unplugging. The unplug lever and the plug are connected by a pivot joint that forms a pivot axis. The unplug lever forms a handle arm and a counter arm that extend away from the pivot joint in opposite directions.

Abstract: A protection circuit for use with a power source includes a Zener diode, a first resistor, and a second resistor, which together define its maximum voltage threshold. The power source is configured to provide an input voltage to an electrical load. The protection circuit further includes a shorting device and a current-limiting safety device. When the input voltage is less than the maximum voltage threshold, the shorting device is maintained in an off-state, causing the input voltage to be provided to the electrical load. When the input voltage is greater than or equal to the maximum voltage threshold, the shorting device switches to the on-state and electrically shorts the power source to a ground, causing the current-limiting safety device to break an electrical connection between the power source and an input point electrically connected to the electrical load, such that the electrical load is electrically disconnected from the power source.
