Abstract: Embodiments herein relate to vehicle filter monitoring systems and methods. In an embodiment, a filter monitoring system is included having a filter sensor device configured to generate data reflecting a filter condition value of a filter and a geolocation circuit configured to determine a present geolocation of a vehicle. The system can also include a system control circuit configured to generate or receive local contaminant concentration values at the present geolocation, evaluate the filter sensor device data to determine at least one of the filter condition value and a change in the filter condition value, and generate at least one of a maintenance recommendation and a routing recommendation based on the local contaminant concentration values, time spent at the geolocation of the vehicle, duty cycle of the vehicle, the filter condition value, and a change in the filter condition value. Other embodiments are also included herein.

Abstract: Embodiments herein relate to fuel monitoring systems and related methods. In an embodiment, a fuel monitoring system for a vehicle is included having a fuel filter sensor device configured to generate data reflecting a filter restriction value of a fuel filter, a geolocation circuit configured to generate or receive geolocation data, and a system control circuit configured to evaluate the sensor data to determine changes in the filter restriction value. The control circuit can receive fuel level data, cross-reference geolocation data and fuel level data to identify refueling locations utilized, and correlate refueling locations with subsequent changes in filter restriction to identify an effect of specific refueling locations on fuel filter loading. In some embodiments, a refueling guidance system for a vehicle is included that can provide route and/or refueling site recommendations based on fuel filter loading rate data. Other embodiments are also included herein.

Abstract: A method for managing document information on an information net, such as the World Wide Web (WWW), comprises the steps of inputting a structured document; extracting selected document properties from the structured document; forming a feature vector representative of the properties; and forming a caricature derived from the feature vector.

Abstract: A down-sampling system for digital waveforms performs real-time, “on the fly”, conversions and results in data of acceptable quality for many applications including applications dealing primarily with speech data. The down-sampler comprises a weight matrix calculator and a loop in which the system takes the input data from the producer's data stream, and at one chunk at a time, the system generates the output data. The loop comprises an input receiver, a chunk receiver, an output chunk generator, a chunk decider for deciding whether there is another chunk in the input, and an input decider for deciding whether there is more input.

Abstract: A system for providing a primarily audio environment for world wide web access includes a system for rendering structured documents using audio, an interface for information exchange to users, a non-keyword based WWW search system and a few miscellaneous features. The system for rendering structured documents using audio includes a pre-rendering system which converts a HTML document into an intermediate document and a rendering system which actually generates an audio output. The interface includes a non-visual browsing system and an interface to users for visual browsing environments.
