Abstract: Various technologies for communicating with systems that communicate using an unknown communications protocol are described herein. A transceiver intercepts a plurality of communications exchanged between two or more transceivers on a communications network. Pattern-recognition algorithms are executed over the plurality of communications, and features of an unknown communications protocol that governs the communications between the two or more transceivers are inferred based upon output of the pattern-recognition algorithms. A communication is formatted based upon the inferred features of the unknown communications protocol, and the communication transmitted to one or more systems on the communications network by way of the transceiver. The communication at least partially conforms to the unknown communications protocol, and so may be interpreted by systems on the network.

Abstract: The various technologies presented herein relate to determining a location of an individual, or an object, when a GPS may be unavailable/occluded. Readings from a plurality of sensors on a mobile device can be generating a plurality of data (e.g., speed, motion, temperature, biometric, etc.) which can be combined to generate a probability of a user of the mobile device being at a particular location, or not. Sensor readings can be weighted to enable sensors having a large effect on a degree of confidence of the probability of the user being determined to be at a location being given priority (e.g., battery priority) versus those sensors which have lesser effect on the degree of confidence. With the user determined to be at a location, information, a notification, an instruction, etc., can be presented to the user, via the mobile device.
