Latest Patents

One of Elder's latest patents is a "Synchronizing method and apparatus." This invention describes a method for developing a series of synchronizing pulses related to input pulses of variable amplitude above a background noise level. The first signal is proportional to the derivative of the rising or falling portion of each input pulse. A second signal is developed related to the first signal, with a decay characteristic that allows the amplitude of the second signal to match the first at a threshold point proportional to the first signal's amplitude. This innovation ensures that the phase of the synchronizing signal is independent of the input pulse amplitude.

Another significant patent is the "Gas analyzer," which is of the non-dispersive infrared type. This gas analyzer detects an infrared beam passing through a sample cell containing a gas mixture. The resulting electrical signals are processed to indicate the concentration of the gas constituents. The design includes temperature stabilization for both the rotary filter wheel and the detector, along with compensation for variations in absorption characteristics due to temperature changes. The motor drive for the rotary filter wheel is servo-controlled based on synchronizing pulses developed directly from the detector output.
