The present invention is configured to determine the weight of a payload of a mobile machine. When the machine is in motion, a force characteristic of the machine is compared with a force characteristic threshold, or range. The payload determination is based upon the force characteristic comparison, and the pressures sensed in at least one of the struts.

Method and apparatus configured to determine the weight of a machine payload

A timing method and timing apparatus are provided for dynamically timing an apparatus. The timing method includes operating the apparatus to be timed, and generating a signal having a zero crossover portion, and generating a timing signal in response to the signal reaching the zero crossover portion. The timing apparatus receives the signal and generates the timing signal in response to the signal reaching the zero crossover portion.

Apparatus for dynamically timing a diesel engine

Dynamic timing indicating apparatus has comparing, zero-crossing detecting and automatic indicating apparatus. The comparing apparatus receives a first input signal and delivers an output signal in response to the input signal. The zero-crossing detection apparatus receives a second input signal which has a zero crossover portion and occurs in timed relation to the first input signal and delivers an output in response to the second input signal. The indicating apparatus automatically indicates the timed relation between the first and second input signals in response to the outputs of the comparing and zero-crossing detecting apparatus.

Dynamic timing indicating apparatus

A strain gauge transducer device externally mounted on a fuel line leading to a diesel engine and a circuit for developing engine timing signals from the transducer device output. The circuit includes a peak voltage detector to detect a peak signal from the transducer device output and a scaling potentiometer which attenuates the peak signal by a preset percentage to a level corresponding to the desired fuel pressure. A comparator compares the attenuated signal to the transducer device output and produces a timing signal when the latter is equal to or exceeds the former.
