Abstract: Various examples are directed to apparatus and methods for providing a sign post flasher assembly. An apparatus includes an elongated assembly having one or more channels, and one or more light sources configured to be placed within the one or more channels. The apparatus also includes an electrically conductive material configured to electrically connect the one or more light sources, and a covering material configured to cover the electrically conductive material to provide a waterproof seal. The elongated assembly is configured to be affixed to and align with a front of a sign post along a length of the sign post, and the electrically conductive material is configured to be connected to a controller to control flashing of the one or more light sources.

Abstract: Devices, systems, and methods for tracking a flying object, and displaying the tracked flying object with additional information regarding the flying object on a display. Digital images from one or more image sensors identify and track flying objects by the velocity and direction of movement, and can convey flight paths, corresponding collision alarms, warnings, or other information on the display.

Abstract: A method of transforming time-domain data to frequency-domain data by means of digital numerical models of damped oscillators, and a spectrograph implemented using said method.

Abstract: A quarter frame end dump trailer has one or more resilient members placed in its drag link in order to permit the use of an air ride suspension in a tandem axle, spread axle or other multiple axle configuration.

Abstract: A digital time fuze for providing an output pulse following a precise, specified time interval, wherein control means extract time interval data from a set signal, the control means thereafter providing a portion of a clock signal to a counter such that the length of the portion of the clock signal provided is determined by the time interval data. Counter means count the number of pulses in the clock signal portion to accumulate a timer count. In response to a start signal, the counter means counts down the timer count according to a count down clock which is provided by the control means and which is proportional to and derived from the clock signal. When the count reaches zero the output pulse is provided.
