Devices and methods for prolonging battery life of an inventory tracking tag. The tag determines its location and reports to remote server over a cellular data connection using the cellular communication subsystem. The remote server assesses whether the tag is within range of a short-range communication network, such as a WiFi network, and sends an instruction message over the cellular data connection to instruct the tag to use the first short-range communication network. The instruction message may include credentials for connecting to the network. The tag disables the cellular communication subsystem, enables the short-range communication subsystem, and requests a connection to the first short-range communication network for the purpose of sending future location reports to the remote server.

A smart card has a light-emitting element, a fingerprint sensor and a microcontroller. An operation of the smart card has a plurality of indication periods to indicate operation statuses of the smart card by the light-emitting element. The control method of the smart card includes generating a light source control signal, controlling a current supplied to the light-emitting element by the microcontroller according to the light source control signal, and decreasing the current supplied to the light-emitting element or stop the current supplied to the light-emitting element during at least one power-saying period in a first indication period of the plurality of indication periods.

In this patent disclosure, various embodiments of using near-field communication (NFC) to facilitate the transfer of data and power between a robotic surgical system and a surgical tool attached to the robotic surgical system are disclosed. In one aspect, a process for automatically managing surgical tool attachment in a robotic surgical system can begin by detecting an attachment of a surgical tool. The process next establishes a secure near-field communication (NFC) link between a first NFC module embedded in the robotic surgical system and a second NFC module embedded in the surgical tool. Next, the process requests tool calibration data from the surgical tool via the secure NFC link. The process subsequently uses the received tool calibration data to initialize the surgical tool so that the surgical tool is ready for use.

An apparatus includes a substantially cylindrical housing, a power source, a processor, a communications interface, and an indicator. During operation, a functionalized coin is detected, by the apparatus, as being within a predefined distance of the apparatus. In response to detecting the presence of the functionalized coin within the predefined distance, the apparatus can cause the indicator to exhibit an indication such as vibration and/or light emission. The indicator can include a vibration motor, or a light-emitting diode (LED). The apparatus is sized to fit within a palm of a hand of a human user. The apparatus can also transmit, via the communications interface, a radio frequency beacon signal, and receive, via the communications interface, a reply to the beacon signal and, in turn, transmit a confirmation of receipt of the reply to the beacon signal, to establish a communications connection between the apparatus and the functionalized coin.

Embodiments of the present disclosure generally relate to a wireless identification tag configured to harvest ambient energy and transmit an identification signal intermittently, and system and methods for use thereof. In one implementation, the tag may include an antenna configured to receive ambient energy. The tag may also include an energy storage component configured to aggregate and store the received ambient energy. The tag may also include a transmitter electrically connected to the energy storage component and configured to transmit the identification signal. The tag may also include a circuit connected to the transmitter and configured to implement an identification transmission rule, to cause the transmitter to delay sending the identification signal even when sufficient energy for transmission of the identification signal is aggregated and stored in the energy storage component.
