The housing further includes a controller, a transceiver, and a water sensor.

Disclosed are techniques to conserve battery of an endpoint device. Example techniques include adjusting the size of messages transmitted by an endpoint device and/or adjusting the transmission rate of an endpoint device. In some configurations, the one or more criteria are used by an endpoint device to determine what data fields to include within a message and/or adjust a transmission rate associated with the transmission of messages by the endpoint device. For instance, the one or more criteria may include the battery level of the device, the time of year, whether the data has already been transmitted by the endpoint device, whether the data has been acknowledged as received by another device, whether the endpoint device has been instructed by another device to reduce the message size and/or adjust the transmission rate, and the like.

A method for operating an electronic consumption-data acquisition device includes wirelessly transferring consumption data to a receiver over a first radio system, operating the consumption-data acquisition device in a first operating mode in which the consumption data is transferred over the first radio system and a second operating mode having a lower rate of transmission and/or readiness to receive compared with the first operating mode, with it being possible to switch between the first and second operating modes. The switchover between the first and second operating modes is performed by a second radio system. A consumption-data acquisition device includes a communication module having a radio apparatus for a second radio system which can be used to perform the switchover between the first and second operating modes.

A wireless motion sensor system comprising a wearable inertial measurement unit, a wireless signal relay unit, and a data analysis server can be used in low power sensing and control applications, such as continuous monitoring and recording of motion and other parameters before, during, and after the occurrence of an unpredictable event. Data from the inertial measurement unit could be analyzed and presented on a graphical presentation unit.

A battery monitoring system includes a self-contained measurement device configured to mount to a battery cell. The self-contained measurement device includes a sensor configured to monitor an operational parameter of the battery cell, and a communication module configured to output a signal indicative of the operational parameter.

A terminal device has measurement sensors for measuring physical quantities of measurement targets. A storage unit stores information determining a mode for activating the measurement sensors. Based on the information stored in the storage unit, a control unit switches all or part of the measurement sensors from a non-activated state to an activated state when the measurement sensors are to be activated. An activation unit includes an activation sensor driven on the basis of environmental changes. The activation unit is configured to activate the control unit on the basis of detection results from the activation sensor when a physical quantity correlated with the physical quantity of the measurement target satisfies a given activation condition.

A measurement device and communication method for the same is disclosed. The measurement device is adapted to communicate with a monitor device employing a bi-directional communication protocol. The measurement device is adapted to operate in a uni-directional communication mode such that it transmits messages irrespective of response messages transmitted to the measurement device.
