Abstract: This clamping tool uses optical distance verification with a laser. Clamping tools, like all tools, are known to be operated improperly. Many tools verify process completion by monitoring the pressure within the pneumatic tool. Previous qualifiers use pressure to determine many things. However, it often misses if a small object impedes a full stroke. With the addition of an optical laser sensor, we are able to determine if a clamping tool reaches full stroke.

Abstract: This system is a tool and monitor assembly that verifies clamps have been activated properly with the tool. The radio controlled clamp tool provides accountability and control with a strain gauge operation. The radio tool is designed to perform the operation of clamp tool, retain the signature and transmit the signal with data to an interface box for error proofing or tool analysis.

Abstract: This system relates to a secure encryption/decryption protocol for elevator displays and controls. The protocol uses an algorithm to scramble information before transmission and reassemble it after transmission. The system uses at least one block of data assembled into unencrypted N-bits of information. An encryption device encodes the data into at least one block of encrypted M-bits of information. A data encryption mask provides an encryption routine which also includes scrambling the data.

Abstract: This interface is an apparatus for controlling a power supply delivering power to a DC powered tool. The interface is connected between the DC power supply and the DC tool wherein the interface is configured to read signals from the tool and control the power supplied by allowing the power supply to run, brake, reverse or jog the tool. A microprocessor is connected to the interface programmed to provide a specific power in response to the signals from the tool read by the interface. The interface includes a number of field effect transistors. They are PFET1, PFET2, NFET1, and NFET2.

Abstract: This dynamic calibration qualifier relates to a tool monitor and assembly qualifier that verifies that the correct number of fasteners have been properly installed into an assembly. The device monitors an analog signature created by the tool and has the ability to dynamically calibrate itself while the tool is running. In the preferred embodiment, the stored variable is a clutch offset identified during a calibration phase. In a pulse tool, the programmed microprocessor is configured to identify and store the peak pressure of the first three pulses which are averaged together. The clutch offset is added to the average pulse value from which the clutch threshold is generated.

Abstract: This qualifier uses multiple thresholds and multiple timers to perform its operations. This assembly qualifier is a counting apparatus that monitors either the pressure of a pulsing air tool. The qualifier includes a microprocessor that is configured to indicate a pulsing region when the measured air pressure is between the third stored air pressure and the fourth stored air pressure.

Abstract: This qualifier uses multiple thresholds and multiple timers to perform its operations. This assembly qualifier is a counting apparatus that monitors either the pressure of an air tool, the current of an electrical tool or the torque of a mechanical wrench to determine if the tool has shutoff at a target torque. The qualifier also determines if some unknown means shuts off the tool. For example, the system detects proper fastening, nuisance trips, double hits, fasteners that are too short, fasteners that are too long, the use of non-use of washers, effective or non-effective pulsing and proper clutch shut off.

Abstract: This design provides an elegant solution to elevator load weighing applications. The purpose of this control is to provide meaningful feedback pertaining to the load that is in the elevator cab. This system can accept any one of four different types of sensor for determining cab displacement. A linear potentiometer, LVDT, proximity sensor on a strain gauge may be used with this system. Load feedback is provided by these different mechanisms. Relays are provided and may be programmed, for example, to turn ON and OFF at user defined loads.

Abstract: This remote control qualifier, typically a radio frequency (RF) qualifier, is an apparatus for monitoring a mechanical torque wrench with torque switch. The torque wrench includes a means for stimulating the torque switch wherein the torque switch can provide an electrical signal upon reaching target torque. The torque wrench also includes a transmitter for sending the electrical signals to a receiver. The RF qualifier is remote and includes a receiver for receiving the electrical signals from the transmitter of the torque wrench. The remote qualifier also includes a means for electrically computationally processing the electrical signals into other signals.

Abstract: This assembly is a torque measuring device that measures the torque output a tool is producing. A hollow torsion tube connects the tool to a reaction arm through the assembly. A torque transducer is attached to the side of the torsion tube. The ends of the torque transducer are attached in a way that transfers the torque output of the tool to the torsion tube. The transducer produces an electrical signal directly proportional to the amount of twisting that occurs in the torsion tube and transducer. A handle also is attached to the torsion tube in a way that allows the handle to rotate 360° around the torsion tube. Since the operator holds the handle instead of the tool, the operators influence on the tool's torque output is removed, increasing the accuracy of the device.

Abstract: This counting apparatus is a tool monitor and assembly qualifier that verifies that the correct number of fasteners have been properly installed into an assembly. When used in conjunction with a pressure tool, proper fastener torque and count can be verified. The device monitors internal tool pressures and has the ability to "learn" the pressure characteristics of the tool during the assembly process. This assembly qualifier is a device that monitors either the pressure of an air tool, the current of an electrical tool or the torque of a mechanical wrench to determine if the tool shut off at a target torque. The qualifier also determines if some unknown means shuts off the tool.
