Abstract: The disclosure presents a signal system that dynamically adjusts the light system duty cycle in response to battery charge levels. The system can be used for solar-powered flashing signs to extend the operational life of the sign during periods of insufficient solar charging. The system incorporates lamps controlled by a microcontroller that monitors battery voltage and adjusts the duty cycle while maintaining flash frequency. The controller implements stepwise duty cycle reduction when battery voltage falls below specified thresholds, substantially extending battery life without sacrificing visibility of the signal system.

Abstract: A system for pin protrusion measurement of a fastener includes a pin protrusion measurement probe having an electronic camera and a probe socket. The probe socket fits over a nut of the fastener and establishes a fixed, stable position of the pin protrusion measurement probe relative to the fastener. Light from the fastener passes through a viewing window in the probe socket, is reflected through a right angle prism, focused by a lens, and forms an image of the fastener in the electronic camera. A real-time monitor display allows an operator to view the image. A computer, connected to the electronic camera, and having a vision system, processes the image of the fastener, and provides the pin protrusion measurement.

Abstract: A system for displaying the status of a plurality of threaded tasks operating in the background includes a status bar; a progress control bar in the status bar for a primary task operating in the background and including a progress bar and first and second action buttons; the progress bar visually representing progress of a primary background operation; the first action button being selectable by a user for initiating an action with respect to the primary background operation and the second action button being selectable by a user for alternately displaying and canceling a drop list of secondary progress control bars for secondary tasks also operating in the background.
