A computer-implemented method manages the execution of one or more processes within a processing period, each process having a completion priority. The method includes determining an interval based on the number of processes currently executing on a processor; executing the one or more processes during the interval; upon reaching the end of the interval, determining a remaining processing time associated with one or more remaining processes; and if the remaining processing time exceeds the difference between the processing period and the interval, terminating one or more remaining processes based on the completion priority of each process.

System for performing load management

A method to separate data transmitted in parallel at arbitrary frequencies within a channel includes: separating a signal from one channel into a plurality of bins representing sub-channels, each bin having a bin frequency; generating a locked frequency by applying a phase locked loop (PLL) to each sub-channel; determining a difference between the locked frequency and the bin frequency; and correlating the signal with a difference between the locked frequency and the bin frequency.

Detector tolerant of frequency misalignment

A receiver which is capable of receiving in parallel data transmitted at arbitrary frequencies within a radio channel includes: a radio frequency (RF) front end to convert an RF signal to a digitized signal; a Fast Fourier Transform (FFT) generator coupled to the RF front-end to separate the digitized signal into a plurality of sub-channels; a bank of phase locked loops (PLLs) coupled to the FFT generator, each PLL operating on a sub-channel with a sub-channel center; and a flag detector coupled to the bank of PLLs to detect variations from the sub-channel center and to recover the usage data transmitted from the end-point.

Receiver capable of parallel demodulation of messages

A remote data collection system for collecting usage data from an endpoint includes a monitoring module coupled to the endpoint, the monitoring module having a wireless transmitter to transmit the usage data. The system also includes a receiver to receive usage data from the wireless transmitter of the monitoring module, the receiver capable of receiving in parallel data transmitted at arbitrary frequencies within a radio channel.
