摘要:
A sensor system comprises a tag. The tag comprises at least one sensor, a radio-frequency chip, and a first antenna. The sensor is adapted to provide an output analogous to a change in an environment of the sensor. The sensor produces an analog output and includes output terminals. The radio-frequency chip comprises a memory element, input terminals and output terminals. The input terminals are disposed in electrical communication with the output terminals of the sensor. The output of the sensor alters the value of at least one bit in the memory of the chip. The first antenna is disposed in electrical communication with the output terminals of the chip.

A sensor system comprising a tag. The tag comprises at least one radio-frequency chip, a first antenna disposed in electrical communication with the chip and a non-conductive coating disposed upon a surface of the tag. The chip comprises a memory element providing electrical storage of a binary coded word comprising at least one bit and output terminals. The antenna is in electrical communication with the output terminals. The non-conductive coating covers the chip and defines a perimeter. The perimeter is disposed over and exposes a portion of the antenna.

Included are embodiments for remotely determining a battery characteristic. Some embodiments include searching for a first wireless signal that identifies the energy storage device and, in response to receiving the first wireless signal, determining a current charge level of the energy storage device. Some embodiments include receiving a second wireless signal from the energy storage device, determining from the second wireless signal, whether the current charge level of the energy storage device reaches a predetermined threshold, and in response to determining that the current charge level of the energy storage device reaches the predetermined threshold, sending, by the computing device, an alert indicating the current charge level.
