A computer-based processing system (e.g., host server) is operable for receiving historical device operation information (power consumption data) collected during operation of the remote battery-operated device in accordance with a first set of operating parameters, including rechargeable battery information (such as the number of charging cycles experienced). The first set of operating parameters enable operation of the battery-operated device in a first operating mode. The processing system calculates an observed battery life for the device based on the received historical power consumption data and a power capacity value representing a power capacity of the battery resident in the device. This observed battery life may be output to a user and used to determine whether the device will meet a predetermined operational life. If not, parameters for the device can be modified and a new projected battery life calculated (simulation), with the new modified parameters controlling power consumption in the device.

A remote sensor including a first wireless interface for sending out data. The remote sensor has a second wireless interface arranged separate from the first wireless interface. The second wireless interface is configured for the wireless transmission of information between the remote sensor and an external device. The invention also relates to a method for communication between a remote sensor and an external device. The method involves creating a communication link between a wireless interface of the remote sensor and a wireless interface of the external device, as well as transmitting information between the remote sensor and the external device by the established communication link. This allows for simple configuration or maintenance of the remote sensor by the external device according to the exchanged information.

A body of a thermometer (1001), a first location to be measured (1002), a second location to be measured (1003) and a third installation location (1004) is established by the thermometer management system. Further, communication lines (1005) are connected to network units at each location to be measured. Network units relay the sensor output from a sensor part to the communication lines. A sensor part is fixed to an object to be measured and sends a sensor output in response to the temperature of the object to be measured. A network unit has a radio frequency identifier (RFID) reader and transmits to the thermometer body commands and the like stored in the memory of an RFID card in response to approach of the RFID card arranged corresponding to a location to be measured. The thermometer body receives the commands and the like and performs predetermined operations.

Embodiments are disclosed that sense vibrations caused by flow of water in pipes, and covert the sensed vibrations into water usage data which can be analyzed, aggregated, and made available to users. In one embodiment, mechanical vibrations of a pipe are sensed, via a piezo-electric sensor attached to an external surface of the pipe, to form analog electrical signals. The analog electrical signals are converted into time-sampled digital data via a microcontroller having analog-to-digital conversion capability. A frequency analysis is performed on the time-sampled digital data, via at least one processor, to generate spectral data. The spectral data is analyzed, via the at least one processor, to determine whether the vibrations are caused by a fluid flowing through the pipe.

A wireless sensor is provided for use in near-to-zero or zero-power consumption applications. The sensor includes a sensing circuit, a modulator connected to the sensing circuit and configured to modulate an input signal using variations in input impedance produced by the sensing circuit to produce a modulated output signal, and a transmitting element such as an antenna to transmit the modulated output signal to a receiver. In some implementations, the sensor includes a pilot sequence generator that may be powered by a received signal from a transmitting node. The input signal is thus modulated by both pilot data and the input impedance. The input signal may be received from the transmitting node. Alternatively, a power source may be provided in the wireless sensor for generating the input signal and/or pilot data.

Disclosed is a system and method for wirelessly monitoring process conditions within a reactor vessel. An array of sensor-enabled radio frequency identification (RFID) tags is placed at known heights within a catalyst bed of a vessel and are used to measure 10 various conditions within the vessel. The sensor-enabled RFID tags are encoded with individual identification codes and are wirelessly linked to multiple transceivers. The use of multiple transceivers allows for the application of triangulation methods to identify the location of each of the sensor-enabled RFID tags in three-dimensional space and for the interrogation of each sensor-enabled RFID tag to receive responsive transponder signals that carry information representative of the sensed condition within the reactor.
