Abstract: Devices, systems, methods, and processes for transmitting and receiving one or more data packets are described herein. A device may face an internal non-deterministic delay in processing causing a gap or an interruption during transmission of the data packet. During the gap, the device can transmit one or more words between the transmission of the data packet. The words can be ignored or discarded by a receiver. The device may transmit the data packet into multiple parts by transmitting the words between the parts. The receiver can receive the parts of the data packet and the words and retrieve the data packet based on the parts of the data packet. The device may set a configurable threshold value indicative of a maximum number of the words that can be transmitted during the gap of the interruption, such that the receiver can efficiently identify and discard a runt packet.

Abstract: Systems and methods for pairing-less device connectivity are disclosed. For example, a group of primary devices are authorized to establish a non-bonded connection with a given secondary device. When the secondary device is in proximity of at least one of the group of primary devices, that primary device may receive a wireless beacon from the secondary device. The system may identify the primary device as an authorized device, perform user presence confirmation processes, and send a command to the primary device to establish the non-bonded connection. Encryption using a network layer or a presentation layer and an application layer of a computer network, instead of a link layer, is utilized for secure data transmission over the non-bonded connection.

Abstract: Systems and methods for presence-based application invocation are disclosed. For example, presence of a personal device and/or user associated with a personal device is detected at a primary device.

Those checks include determining whether one or more conditions are satisfied, determining current usage of the application and/or the primary device indicates desirability to automatically invoke the application, and/or whether the application has been enabled for use on the primary device.

Abstract: A multi-wavelength active marker includes a first light source emitting a first wavelength of light, a second light source emitting a second wavelength of light different from the first wavelength, and a converging light-combining waveguide that is arranged adjacent the first and the second light sources. The waveguide guides the light emitted from the first and second light sources to a diffuser for concurrent emission of both of the first and second wavelengths from the diffuser. The multi-wavelength active marker may be used in co-calibration of disparate camera systems, such as a motion capture camera system and a cinema camera, which are not sensitive to the same wavelengths for calibration purposes.

Abstract: A system includes a light source that emits broadband light through a test cassette containing a fluid. A spectrometer disperses the broadband light, after passing through the test cassette, onto a plurality of pixel detectors of a detector array. A digitizer reads an array of raw spectral values from the detector array. A signal processing circuit deconvolves, based on a spectral response of each of the plurality of pixel detectors, the array of raw spectral values to generate an array of deconvolved spectral values; feeds the array of deconvolved spectral values into a trained machine-learning model to obtain an indication of the presence of one or more constituents in the fluid; and outputs the indication. The fluid may be human saliva or another biological fluid obtained from a patient. The indication may be used to diagnose the patient with a disease or condition.

Abstract: A system for atom interferometry includes one laser configured to generate an output beam; an acousto-optic deflector disposed to generate two diffracted beams that are spatially offset with identical polarizations; and a birefringent crystal disposed to receive the two diffracted beams, where one of the two diffracted beams is passed through a half wave plate so that the two diffracted beams have orthogonal polarizations, where the birefringent crystal further disposed and selected in size to enable the two diffracted beams to re-overlap upon exiting the birefringent crystal by having one of the two diffracted beams walk toward the other of the two diffracted beams in the birefringent crystal, where the two diffracted beams have minimal path length differences so that the two diffracted beams are useable for interferometry.

Abstract: A system and method provide access to a remote resource locally by requesting content from an original address and receiving a first requested content and a first redirect uniform resource locator in response. The first redirect uniform resource locator reroutes the navigation from the original address requested to a redirect destination address that serves an access token. The system and method unlock access to a second application programming interface in response to validating the access token served by the redirect destination address and receives a second requested content and a second redirect uniform resource locator in response to transmitting the access token to the original address. The second redirect uniform resource locator transfers a user to an environment residing at an address different from the original address and the redirect destination address.

A device may face an internal non-deterministic delay in processing causing a gap or an interruption during transmission of the data packet.

Abstract: Embodiments herein describe an atomic sensor that includes a photonic die that outputs optical signals on a top surface. These optical signals can be directed and shaped as needed to satisfy a particular type of atomic sensor. In one embodiment, an atomic source (e.g., rubidium or cesium) is disposed on the photonic chip to emit atoms when heated. A collimator can then direct the emitted atoms along a path that intersects with the optical signals. This intersection can be used to detect motion (e.g., rotation and acceleration) of the atomic sensor.
