In this patent disclosure, various embodiments of using near-field communication (NFC) to facilitate secure data exchange between a robotic surgical system and a surgical tool attached onto the robotic surgical system are disclosed. In one aspect, a process for enabling secure data exchange between a robotic surgical system and a surgical tool begins by detecting a coupling of the surgical tool onto the robotic surgical system. The process next establishes a NFC link between a first NFC module embedded in the robotic surgical system and a second NFC module embedded in the surgical tool. The process then determines whether the surgical tool is authenticated to the robotic surgical system via the NFC link. Next, in response to the authentication of the surgical tool, the process establishes secure data exchange between the robotic surgical system and the surgical tool.

Embodiments of the present disclosure generally relate to a wireless identification tag with varying identity, and system and methods for use thereof. In one implementation, the tag may include at least one transmitter configured to transmit a tag ID. The tag may also include at least one circuit. The at least one circuit may be configured to receive a first trigger at a first time and generate in a quasi-random manner a first decipherable ID uniquely identifying the tag, and cause the at least one transmitter to transmit the first decipherable ID. The at least one circuit may also be configured to receive a second trigger at a second time and generate in a quasi-random manner a second decipherable ID different from the first decipherable ID and uniquely identifying the tag, and cause the at least one transmitter to transmit the second decipherable ID.

A sensor assembly providing a physical property of a vehicle, e.g. tire pressure of a wheel of an aircraft, comprises electronic circuitry including a locking arrangement and sensor suited to sense the physical property and an exhaustable power source, e.g. a battery. For prolonged shelf life, a first and a second switch means are functionally arranged between power source and circuitry. The second switch means is controlled by the locking arrangement, whereas the first switch means is controllable from outside the sensor assembly, e.g. by a magnetic field. The first switch means is arranged to switch the power to the electronic circuitry, whereby the locking arrangement is powered, too. In consequence, the locking arrangement is capable to close the second switch means. Thereafter, a further stimulus to the first switch will no more be capable to switch the sensor off, unless the locking arrangement enables it again by opening the second switch means.

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 a transmitter configured to transmit a first signal to a first receiver in a first frequency, and to transmit a second signal to a second receiver in the first frequency. The tag may also include an energy storage component configured for collecting and storing ambient energy and for powering transmission of the transmitter. The tag may also include a circuit configured to monitor energy stored in the energy storage component, and to prevent the transmitter from transmitting the first signal to the first receiver when the energy stored in the energy storage component is insufficient to transmit the second signal to the second receiver.

Embodiments of the present disclosure generally relate to a wireless identification tag triggerable by an EAS gate while remaining invisible to the EAS gate, and system and methods for use thereof. In one implementation, the tag may include an antenna tuned to receive energy transmitted in at least one EAS gate frequency range and configured to be non-detectable by the EAS gate. The tag may also include a transmitter configured to send an identification signal and an energy storage component for powering the transmitter. The tag may also include a circuit connected to the antenna. The circuit may be configured to detect energy transmitted from the EAS gate in at least one of the EAS gate frequency ranges, and to cause the transmitter to transmit, to a receiver other than the EAS gate, the identification signal in a frequency outside the EAS gate frequency ranges.

Embodiments of the present disclosure generally relate to a wireless identification tag with varying ID transmission timing, and system and methods for use thereof. In one implementation, the tag may include at least one transmitter and an energy storage component electrically connected to the at least one transmitter. The energy storage component may be configured to collect and store ambient energy and to power transmission of the at least one transmitter. The tag may also include at least one circuit. The at least one circuit may be configured to cause the at least one transmitter to transmit a sequence of identification signals in non-uniform intervals such that times between identification signal transmissions of three consecutive transmissions vary.

Described herein is a technology for a wakeup pattern - data stream correlation by a detector to provide a trigger condition for a microcontroller in a wakeup receiver (WuRX). For example, the detector includes a data packet layer with a plurality of index registers that are updated through sampling of data streams. A sample clock is coupled to each of the plurality of index registers to independently activate each of the plurality of index registers. A shared comparator will then compare the updated plurality of index registers to corresponding shift registers that are initialized with rotating wakeup pattern bits. Based upon a number of matching results, the detector generates a triggering signal that facilitates a low-power operating mode to a high-power operating mode change.

Embodiments of the present disclosure generally relate to systems and methods for providing privacy to downstream owners of electronically tagged goods. In one implementation, the system may include at least one processor that may be configured to store IDs for a plurality of tags including at least a first owner ID and a second owner ID for a particular tag; associate first information of the particular tag with the first owner ID at a time when the first owner of the particular tag is recorded as owning the tag; record a transaction transferring ownership of the particular tag from the first owner to a second owner; and after the transfer of ownership, associate second information of the particular tag with the second owner ID, and prevent the second owner from accessing the first information.

Embodiments of the present disclosure generally relate to a wireless identification tag configured to collect and store ambient energy for use in delayed transmission, and system and methods for use thereof. In one implementation, the tag may include a receiver for receiving ambient energy; a first capacitor for storing the ambient energy; and a second capacitor for collecting and storing the ambient energy. The second capacitor may have lower capacitance than the first capacitor. The tag may also include an inductor interconnecting the first capacitor and the second capacitor. The tag may also include circuitry configured such that ambient energy received by the receiver is initially stored in the second capacitor and subsequently transferred to and stored in the first capacitor. The tag may also include a transmitter electrically connected to first capacitor, to enable the energy stored in the first capacitor to power the transmitter.
