The multi-trigger versions have programmable logic controller-type functionality for incorporating interlocks, latches, dynamic delay adjustment, and trigger noise suppression. Triggers are formed by logically combining the inputs and outputs in And, Or, Xor, and Negated forms. LIDAR applications use digital delay generators. A channel is used ...

The motor rotor shape is a cylinder mounted on a shaft. Internally it contains longitudinal conductive bars (usually made of aluminium or copper) set into grooves and connected at both ends by shorting rings forming a cage-like shape. The name is derived from the similarity between this rings-and-bars winding and a squirrel cage.
Modern time delay combination locks can have many functions such as multiple different codes, pre-set time lock settings (open and close times), pre-set vacation times (e.g. Christmas Day), dual code facility, and a full audit trail providing a detailed record of the lock history showing who opened the lock, when and how long it was open.

A delay line interferometer (DLI) can be a Mach–Zehnder interferometer or Michelson interferometer based on two-beam interference, in which one beam is time-delayed to the other by a desired interval. Delay line interferometers are also known as optical DPSK demodulators. They convert a phase-keyed signal into an amplitude-keyed signal.
On third rail systems, the outer vehicles usually carry the pick up shoes with the motor vehicles receiving the current via intra-unit connections. Many modern two-car EMU sets are set up as twin or "married pair" units. While both units in a married pair are typically driving motors, the ancillary equipment (air compressor and tanks, batteries ...
The Adjustable Ranging Telescope (ART) is a weapons sighting system typically used as a military rifle scope which was initially designed for service in the Vietnam War. It was developed and patented by James M. Leatherwood. It combines a range-finding scale inside of a telescopic sight with an adjustable cam integrated into the scope's mount ...
