    Abstract: Unmanned aerial vehicle (UAV) capture devices and methods of operation are disclosed. A UAV capture device may include a netting system including a net launch device and a net, a propulsion system including a plurality of propellers coupled to one or more motors, a positioning system, a camera system, and a processing system coupled to the netting system, the propulsion system, the positioning system, and the camera system. The processing system may include logic to operate the propulsion system to autonomously navigate to a general location of a target UAV, to operate the propulsion system to pursue the target UAV, to deploy the netting system to propel the net at the target UAV, and to confirm if the target UAV is captured in the net. Other aspects, embodiments, and features are also included.

    Abstract: A photoplethysmography (PPG) circuit or non-contact camera obtains PPG signals at a plurality of wavelengths. A signal processing module obtains at least a first spectral response around a first wavelength and a second spectral response around a second wavelength. The signal processing device generates PPG input data using the PPG signals, wherein the PPG input data includes one or more parameters obtained from each of the first spectral response and the second spectral response. A neural network processing device generates an input vector including the PPG input data and determines an output vector including health data, wherein the health data includes for example, an oxygen saturation level, a glucose level or a blood alcohol level.

    Abstract: A multilayer printed circuit board is provided having a first conductive layer and a first plating resist selectively positioned within the first conductive layer. A second plating resist may be selectively positioned within a second conductive layer. A through hole extends through the first plating resist in the first conductive layer and the second plating resist in the second conductive layer. An interior surface of the through hole is plated with a conductive material except along a length between the first plating resist and the second plating resist. This forms a partitioned plated through hole having a first via segment electrically isolated from a second via segment.

    Abstract: A biosensor is implemented in an earpiece and includes an activity monitoring circuit that detects an activity level of a user and an optical circuit that detects a plurality of spectral responses at a plurality of wavelengths from light reflected from skin of the user. The biosensor determines a heart rate and an oxygen saturation level using the plurality of spectral responses and determines whether the heart rate or the oxygen saturation level reaches a predetermined threshold for the activity level of the user. The biosensor generates an alert and transmits the alert wirelessly to a remote device.

    Abstract: One feature pertains to a scissor-based carrier assembly for a mass storage device used in a storage computer system. The carrier assembly has fixed and moving parts allowing the carrier to change from a retracted state to insert or remove the mass storage device into or from a storage enclosure to an extended state to couple the mass storage device with a connector of the storage computer system.

    Abstract: Laminate structures including hole plugs, and methods for forming a hole plug in a laminate structure are provided. A laminate structure may be formed with at least a dielectric layer and a first conductive foil on a first side of the dielectric layer. A blind hole may be formed in the laminate structure extending toward the first conductive foil from a second side of the dielectric layer and at least partially through the dielectric layer, the blind hole including a hole depth to hole diameter aspect ratio of less than ten (10) to one (1). Via fill ink may be disposed in the blind hole, and the via fill ink may be dried and/or cured to form a hole plug.
