Abstract: Described herein are methods and devices for determining estimate information related to at least one potential vehicle fix for a vehicle based on vehicle information and content of a vehicle repair database. According to an example method, a computing device can receive vehicle information that includes a vehicle identifier and vehicle-usage data for a vehicle. The computing device can then determine repair information that relates to the vehicle from the vehicle repair database based on the vehicle information. The repair information can include at least one potential vehicle fix to a given malfunction. The example method can further involve determining estimate information related to the at least one potential vehicle fix and providing the estimate information to a communication network.

Abstract: A frequency transducer for monitoring frequency in a power line wherein a frequency representative signal is generated which is twice the frequency of the signal to be monitored in the power line, the frequency representative signal is shaped into a triggering output signal which is supplied as one input to a comparator in a comparator/timer circuit. A second input to the comparator is provided by a timing circuit which produces a reference signal as that second input, said reference signal having a constant non-zero duration, the magnitude of which is dependent upon the timing constant of a resistive-capacitive circuit; said resistive-capacitive circuit being charged by a constant charging current of high value to ensure that variances in the timing constant due to temperature, humidity, contamination and the like are small when considered as a percentage figure.
