A method of synchronizing respective state transitions in a group of devices including at least one responding device is disclosed. The group of devices is communicatively coupled to an initiating device via a communication network. The method includes the at least one responding device receiving a trigger message from the initiating device. The trigger message includes a state transition time or a time from which a state transition time is obtainable. The method further includes the at least one responding device jointly making a respective state transition at the state transition time. A responding device, and a system including the initiating device and the responding device are also disclosed.

Method and a system for synchronising respective state transitions in a group of devices

A method for deciding the relationship between a physical property and a threshold, comprising measuring a physical property to obtain a measured value, calculating the distribution of actual values for the physical property, calculating the error distribution of the obtained measured value, calculating the penalty associated with an erroneous decision, and calculating a margin based on the expected loss from selecting at least one possible actual value as a function of the calculated distribution of actual values, the calculated error distribution of the measured value, and the calculated penalty associated with an erroneous decision. Embodiments including a system and apparatus are also disclosed.

Method for comparing a value to a threshold in the presence of uncertainty

A method of locating an acoustic source, the method comprising sampling said acoustic source at a plurality of acoustic receivers having different locations, each acoustic receiver time-stamping a respective received acoustic sample using a system time, each acoustic receiver sending said time-stamped acoustic sample to a central controller, the central controller determining the location of the acoustic source in response to receiving the time-stamped sound source samples from the plurality of receivers.

Acoustic location and enhancement

A system and method is shown for determining the spatial boundary of certain measurable phenomena, such as broadcast signals, at various locations within geographical areas covered by the phenomenon. Data representing relative signal quality at various locations within the geographical area is created within a mobile device, such as a cell phone capable of receiving the phenomenon. The data is stored and refined within the device so as to define weak signal quality areas within at least a portion of the geographical area traveled by the mobile device. The refinement, which in one embodiment comprises coalescing and splitting stored data locations in the device allows for long storage periods by reducing memory requirements. By devoting the majority of memory to locations in the vicinity of the good/bad boundary, the most detailed picture possible of the boundary is achieved for a given amount of memory. By collecting such data from a plurality of such devices, a central system can map the signal strength over the entire geographical area.

System and method for wireless coverage detection

Decimation of data from a fixed length queue retaining a representative sample of the old data. Exponential decimation removes every nth sample. Dithered exponential decimation offsets the exponential decimation approach by a probabilistic amount. Recursive decimation selects a portion of the queue and removes elements.

Decimation of fixed length queues having a number of position for holding data wherein new data is favored over old data

Disclosed are systems and methods for utilizing a pool of mobile devices in probing operations comprising a probing host system including probe management and data management operative aspects, and a pool of mobile devices, one or more of which are operative under control of the probe management to provide probing data to the data management, wherein the one or more mobile devices comprise mobile devices for which location and movement is not under control of the probing host system.

Systems and methods for measurement and/or control using mobile probes

A system and method is disclosed for managing bandwidth in a wireless probe measurement system that may include receiving an indicator at the wireless probe to begin taking measurements of one or more variables, measuring the one or more variables, calculating a set of statistical values at the wireless probe using the measured one or more variables, and transmitting the set of statistical values to a central station.

Bandwidth management in a wireless measurement system using statistical processing of measurement data

An input apparatus is disclosed having a hand-sensing system, a wake-up detector, and a microcontroller. After a period of inactivity, the apparatus is placed into a sleep mode to conserve power. During the sleep mode, an electrical property that the hand-sensing system presents to the wake-up circuit is measured. If the electrical property exceeds a predetermined level, then the input apparatus is activated. In alternative embodiments, an accelerometer, a pressure switch, or a computer system's response can be used to trigger the activation of the input apparatus.

Wake-up detection method and apparatus embodying the same

Embodiments of the present invention reconstruct an underlying phenomenon without the need for predicting a functional form for that signal, by establishing an upper bound and a lower bound for the value of the phenomenon at every point within a measurement space. By acquiring a large enough number of measurements of the phenomenon, a sufficiently high probability that the value of said phenomenon lies between said upper and said lower bound at every point within said measurement space may be established.

Confidence blanket for randomly-located measurements

One embodiment of the present invention separates the region of measurement space into a plurality of sub-regions and calculates a confidence, for reconstruction of an underlying signal within said space, corresponding to each of the sub-regions. This embodiment can then accept measurements from mobile measuring devices within said measurement space and store those measurements if they originate from devices in sub-regions having a confidence below an acceptable value.

Adaptive data collection

A system with a set of modules having synchronized timing. The synchronized timing of the modules enables precise coordination of measurements and stimuli for an arbitrary number of modules. The modules communicate and maintain time synchronization using a communication mechanism that may be adapted to localized positioning of modules and/or widely dispersed positioning of modules with no change to the underlying functionality in the modules.

Modular system with synchronized timing

Process for generating unit names from a nonorthogonal set of units. Given a vector of exponents describing a target unit in terms of SI units, and a table of user defined units which may be nonorthogonal, one or more result unit names equivalent to the target unit are generated by recursively searching the table of user defined units, reducing the magnitude of the target in each step.
