Described herein is a framework for outdoor localization. In accordance with one aspect of the framework, a set of hotspot labels are received from one or more user devices connected to an outdoor wireless local area network. Manifold learning may be performed based on the set of hotspot labels to construct one or more manifolds. Using the one or more constructed manifolds, the framework may then estimate a location of a particular user device associated with a query record received from during an online location query.

Outdoor localization using hotspot labels

Systems and methods for optimizing the task scheduling efficiency of firmware and/or software associated with optoelectronic transceiver devices. In one example, a scheduling module executes microcode that schedules tasks based on the operational parameters. The scheduling module compares operational parameters with their last known values and then flags necessary tasks to be initiated. The scheduling module flags only those tasks that rely on a particular operational parameter and only if the operational parameter has changed in value since the most recent time that it has been measured. Specifically, the scheduling module identifies leading tasks and dependent tasks and flags tasks only if data that relies on the operating parameter has changed since a previous task scheduling determination.

Task scheduling of fiber-optic transceiver firmware

A method of managing storage of digital diagnostics parameters on a transceiver device may include loading persistent digital diagnostics parameters from a persistent memory into a system memory and resetting non-persistent digital diagnostics parameters, receiving updates to the non-persistent digital diagnostics parameters in the system memory, and writing the updates to the non-persistent digital diagnostic parameters in the system memory to the persistent memory.

Digital diagnostics parameter storage

A firmware control method for the optimized use of a single A/D converter to measure multiple analog signals with asymmetric requirements on sampling rate including a lookup table design procedure and an acquisition algorithm. Since diagnostic analog parameter values require differing sampling rates to be effectively measured, the schedule for converting those values to digital value should correspond to the associated sampling rate. The present invention involves the creation and subsequent implementation of a scheduling table based on the required sampling rates of the operational parameters to be converted.
