    Abstract: Techniques are disclosed for using synthetic jet technology as an air delivery device for sensing applications. In particular, a synthetic jet device is used to deliver a controlled airflow or other fluidic flow to a sensor measurement area. Such a sensing system can be used to detect accurate concentration of target features present in the ambient surroundings, such as gases, particles, solutions, mixtures, and any other environmental features that can be sensed from a controlled airflow. An example application is air quality monitoring by using one or more synthetic jet devices to deliver a known or otherwise controlled airflow to a sensing area, thereby allowing for detection of harmful or otherwise unacceptable concentrations of particulate matter, gases, or air pollutants. In some embodiments, a synthetic jet device is operatively coupled with a sensor via a flow channel in a common housing, so as to provide a controlled flow sensing system.

    Abstract: Embodiments include a synthetic jet device formed within layers of a package substrate, such as to provide a controlled airflow for sensing or cooling applications. The jet device includes an electromagnetically driven vibrating membrane of conductive material between a top and bottom cavity. A top lid with an opening covers the top cavity, and a permanent magnet is below the bottom cavity. An alternating current signal conducted through the membrane causes the membrane to vibrate in the presence of a magnetic field caused by the permanent magnet. By being manufactured with package forming processes, the jet (1) is manufactured more cost-effectively than by using silicon chip or wafer processing; (2) is easily integrated as part of and with the other layers of a package substrate; and (3) can be driven by a chip mounted on the package. Embodiments also include systems having and processes for forming the jet.

    Abstract: A wearable device (“WD”) stores a token after its wearer completes a successful strong authentication on a primary protected device (“primary PD”). Other protected devices (“secondary PDs”) recognize the stored token as representing a strong authentication and grant the user access while the user continues to wear the WD within a “digital leash-length” proximity. The WD constantly monitors whether the user continues to wear the device. Upon sensing that the user has removed the WD, the WD deletes, disables, or invalidates the token, The user must then repeat the strong authentication to gain further access to the protected devices.

    Abstract: Techniques are disclosed for particulate matter (PM) measurement in a medium (such as air) using flat-top intensity laser sheet beam generation. The techniques for generating the laser sheet beam may include nonspecialized optical elements (e.g., aspherical, spherical, biconvex, and/or cylindrical lenses) that are cost-effective, reduce the overall footprint of the system, and also provide for relatively increased power efficiencies compared to conventional techniques. The PM measurement system may use the laser sheet beam generated in combination with a medium flow channel to pass the medium through the laser sheet beam, thereby causing particulates within the medium to scatter light, which can be detected using a light sensor (e.g., a photodetector). The scattered light signals can then be analyzed to match them with corresponding particulate sizes and the amount of signals per particulate size can also be determined to measure the size and count of particulates within the medium.

    Abstract: An initial authentication of a user, if successful, causes a token to be stored on, and presented from, a wearable device (WD). The WD continually monitors one or more of the wearer's vital signs to confirm that (1) the WD is being worn by a living person rather than an inanimate simulacrum, and (2) the WD is still worn by the same person who underwent the authentication. The token can be read by a token-reader on at least one protected device (PD). If the token is valid, its presentation serves as authentication and the token-reader grants the user access to the PD. If the WD vital-sign signal is interrupted when the user removes the WD, the WD stops presenting the token and can no longer be used to access a PD.

The computing device includes a sensor hub and a magnetic sensor communicably coupled to the sensor hub. The magnetic sensor is configured to collect sensor data corresponding to the computing device. The computing device also includes a processor that is configured to execute stored instructions and a storage device that stores instructions. The storage device includes processor executable code that, when executed by the processor, is configured to determine a system state of the computing device and send the determined system state of the computing device to the sensor hub. The sensor hub is configured to dynamically calibrate the magnetic sensor based on the sensor data collected via the magnetic sensor and the determined system state of the computing device.
