Abstract: A vehicle control system and method may receive state information from a vehicle group having one or more vehicles. The state information may indicate an operational parameter of one of the vehicles. The controller may direct a display device to present one or more statuses of the one or more vehicles based at least in part on the state information that is received by the controller. This state information may be used to notify an operator of a potential component fault before continued operation of the vehicle group further damages the component or a vehicle. In another example, the state information may be used to control or change operation of one vehicle based on the state or status of another vehicle, such as by changing movement of one or more drones in a swarm responsive to a lower state of charge of another drone in the same swarm.

Abstract: A humidification system for delivering humidified gases to a user can include a heater base, humidification chamber having an inlet, outlet, and associated fluid conduit, and breathing circuit including a supply conduit, inspiratory conduit, and optional expiratory conduit. The humidification system can include various features to help make set-up less difficult and time-consuming. For example, the supply conduit, inspiratory conduit, and optional expiratory conduit can be coupled into a one-piece circuit to aid set-up. Various components can be color-coded and can have corresponding structures to indicate which components should be connected to one another during set-up. Such features can also help make the set-up process more intuitive for an operator, which can reduce the need for specialized training and reduce the number of potential errors.

Abstract: Techniques are provided to synchronize a remote power switch at a power receiver end of a power cable with a first power switch operation at a power source end of the cable, without any physical or data communication means for synchronization. This process may involve synchronization of a MOSFET-type switch with voltage pulsing at the power source cable end to a MOSFET-type isolation switch at the power receiver cable end to provide (voltage or load) power during the On-time and safety testing for a shock hazard during the Off-time. This method synchronizes switching pulses by sensing and synchronizing on the cable switching voltage transients from the source side. This method also involves blanking the additional switching voltage transients on the cable generated after the synchronized switching begins to maintain proper synchronization. These techniques may be used for a single-pair pulse power cable or with multi-pair multi-phase pulse power cables.

Abstract: Methods and apparatuses are described for predicting compliance of text documents with a ruleset using self-supervised machine learning. A server executes an NLP teacher model on first unlabeled sentences to generate a first compliance pseudo-label for each first unlabeled sentence. The server trains an NLP student model using the first unlabeled sentences and first compliance pseudo-labels, including injecting input noise by aggregating each unlabeled sentence with one or more sentences adjacent to each unlabeled sentence into a sentence block and providing the aggregated sentence blocks as input to train the NLP student model. The server executes the trained NLP student model, using second unlabeled sentences, to generate a second compliance pseudo-label for each second unlabeled sentence. The server determines compliance of the second sentences with one or more rulesets using the second compliance pseudo-labels.

Abstract: In an example embodiment, a deep learning algorithm is introduced that operates on a transition matrix formed from user activities in an online network. The transition matrix records the frequencies that particular transitions between paths of user activity have occurred (e.g., the user performed a login activity, which has one path in the network, and then performed a profile view action, which has another path in the network). Each transition matrix corresponds to a different user's activities.

Abstract: Stacked integrated circuit devices, chip packages and methods for operating a chip package are described herein that provide an increased level of backside protection from physical attacks that could compromise confidentiality or authentication of the integrated circuit device. In one example, a chip stack includes a sacrificial integrated circuit (IC) die stacked with a primary IC die. The sacrificial IC die includes a first split key information source. The primary IC die has security circuitry configured to generate an encryption key based at least in part on first split key information transmitted from the sacrificial IC die across a die-to-die interface to the primary IC die. Separation of the dies to probe or modify of the primary IC die would cause the destruction of split key information required to operate the functional circuitry of the primary IC die.

Abstract: In one embodiment, a first device obtains generic attribute (GATT) information from a second device. The first device also obtains long term key information by forming a Bluetooth connection with a second device. The first device performs an exchange with the second device to validate the long term key information. The first device obtains, based on the exchange, updated GATT information from the second device, when the long term key information is no longer valid.

Abstract: A vehicle detection system warns snowmobilers of other approaching vehicles with potential risk of collision. To better prevent accidents, the system calculates collision risks and warns the rider based on level of risk. When riding in groups, a member can press a stop request button to ask the group to slow down. When a member exits the group, everyone in the group will receive a message, alerts or indication with the update. The vehicle detection system utilizes Bluetooth® low energy (BLE), LoRaWAN® technologies and/or global positioning system technologies and is designed to detect other devices in the region and use acquired information to calculate proximity and risk of collision.

Abstract: An imaging system and method includes a rolling shutter sensor that captures a plurality of images of a scene, a time-varying illumination source that illuminates the scene, and a processor that receives the plurality of images from the rolling shutter sensor and separates the plurality of images into a plurality of feeds. Each of the plurality of images is captured as a series of lines. The rolling shutter sensor and the time-varying illumination source are operated synchronously to cause a plurality of on-cadence lines of the rolling shutter sensor to receive more illumination from the time-varying illumination source than a plurality of off-cadence lines of the rolling shutter sensor. Each of the plurality of feeds has a different contribution of the time-varying illumination source to an overall illumination of the scene.
