  • Patent number: 10498399
    Abstract: Near field detection using a magnetometer is disclosed. A transmitter may distort magnetometer measurements of Earth's magnetic field by producing rapid but controlled fluctuations to encode a specific message in a manipulated magnetic field. When a mobile device is brought in range of the transmitter, a magnetometer of the mobile device detects that manipulated magnetic field. An application running on the mobile device forms messages based on the magnetometer output. In response to detecting the specific message, the application may execute an action on the mobile device or a remote device. NFC read-based near field detection similarly involves the application accessing an NFC chip of the mobile device, and scanning for one or more particular NFC tags that are read by the NFC chip. In response to detecting a particular NFC tag, the application executes an action on the mobile device or a remote device.

  • Patent number: 9486128
    Abstract: A surgical imaging system includes a light source configured to illuminate a portion of a surgical environment and a light sensor configured to receive light from the illuminated portion in response to the illumination. The surgical imaging system determines spectrographic content of the received light and uses the determined spectrographic content to identify the illuminated portion of the surgical environment; for example, to determine that the portion contains a surgical instrument, a foreign body, a suture, a particular type of tissue, a blood vessel, and/or a fluorescent marker. This identification of the illuminated portion of the surgical environment could be used to implement a surgical intervention. For example, a surgical laser could be operated, based on such generated identification information, to ablate cancerous tissue in the surgical environment that is marked with a fluorophore while avoiding ablating any sutures or surgical instruments disposed in the surgical environment.

  • Patent number: 9411993
    Abstract: Systems and methods for use in detecting the presence of an RFID device are provided. One RFID detection system includes a detection circuit that includes an oscillating circuit. The detection circuit is configured to hold the RFID detection system in a low power mode in which the RFID detection system is configured to not actively attempt to communicate with nearby RFID devices. The detection circuit is further configured to monitor one or more parameters of a signal of the oscillating circuit and compare the one or more monitored parameters to one or more reference parameters. The detection circuit is further configured to, based on the comparison, determine whether to transition the RFID detection system from the low power mode into an active communication mode in which the RFID detection system is configured to actively attempt to communicate with nearby RFID devices.

  • Patent number: 9412243
    Abstract: A portable alarm system designed for unoccupied unsecured locations, such as construction sites, machinery, campsites and the like. The alarm system defines a continuous monitoring line about the perimeter of the unsecured location using a plurality of wireless sensors attached to a flexible non-stretchable tape suspended between to vertical poles. The system has motion-sensing/detecting capabilities such that any movement of a housing where the microprocessor of the system is located generates audible/visual alarm. Each of the wireless sensors has a magnet and a transmitter positionable within a predetermined distance from the magnet. If the intruder tampers with the tape and increases the distance between the magnet the transmitter, the alarm is activated as well.

  • Patent number: 9406212
    Abstract: An automated process for monitoring and controlling contamination activity in a production area comprises capturing image from the production area over a period of time, processing the image data with a computer to determine whether a contamination event has occurred in the production area, and activating a contamination control device in accordance with the processing of the image data. The contamination event can be a germ-releasing event from an individual in the production area, a pipe leaking fluid into the production area, etc. The automated monitoring and control may also determine whether an article of contamination control equipment (e.g., face mask, glove, etc) is properly positioned on the individual to prevent the contamination from entering the production area in a form that could contaminate product, equipment, or the production area itself.

  • Patent number: 9384376
    Abstract: We describe an RFID tag reading system comprising a plurality of transmit/receive antennas to provide spatial transmit/receive signal diversity, and a tag signal decoder. The system combines received RF signals from the antennas, and the antennas are spaced apart from one another sufficiently for one said antenna not to be within the near field of another. The system performs a tag inventory cycle comprising a plurality of tag read rounds, each having a set of time slots during which a said tag is able to transmit tag data including a tag ID. The system is configured to perform, during a tag inventory cycle, one or both of: a change in a frequency of the tag interrogation signals transmitted simultaneously from the plurality of antennas, and a change in a relative phase of a the RF tag interrogation signal transmitted from one of the antennas with respect to another.
