Abstract: An example device includes a page sensor to detect a page of a print medium picked from a source tray of a printer. The device further includes a processor connected to the page sensor. The processor is to determine a delay in detection by the page sensor of the page conveyed by a page feed mechanism. In response to determination of the delay, the processor is to control the page feed mechanism to continue to convey the page through the printer and the processor is further to trigger the printer to reprint data intended for the page to a subsequently picked page of print medium.

Abstract: Cardiac resynchronization therapy (CRT) delivered to a heart of a patient may be adjusted based on detection of a surrogate indication of the intrinsic atrioventricular conduction of the heart. In some examples, the surrogate indication is determined to be a sense event of the first depolarizing ventricle of the heart within a predetermined period of time following the delivery of a fusion pacing stimulus to the later depolarizing ventricle. In some examples, the CRT is switched from a fusion pacing configuration to a biventricular pacing configuration if the surrogate indication is not detected, and the CRT is maintained in a fusion pacing configuration if the surrogate indication is detected.

Abstract: Disclosed is a churn prediction system that predicts with a high level of accuracy which users will and which users will not stop opening the app over a 30-day time period. To this end a model is created using historical event data where the churn-related behavior of each user is known. New event data is then applied to the model to determine the likelihood of each user churning in the future. With these prediction scores a user is then qualified as falling into one of three classifications: low-risk, medium-risk, or high-risk of churn.

Abstract: Systems and methods for exchanging clinical data among parties involved in a clinical trial. The system comprises a clinical data exchange controller, a first repository and a second repository. Repository configuration information comprises: a connection to a target repository, scope of capacities, and a rule set. Repository configuration information for the first repository is received at the first repository, and repository configuration information for the second repository is received at the second repository. When there is a change defined in the rule set happened in the first repository, a request for data transfer is sent to the clinical data exchange controller, and the clinical data exchange controller then transfers the data to the target repository based on the rule set.

Abstract: Syringes are described herein. A syringe includes a syringe body, a first plunger, a biasing member, and a priming indicator. The syringe body defines a syringe cavity, a syringe port, and an indicator window, wherein the syringe port is in fluid communication with the syringe cavity. The first plunger comprises a first plunger shaft extending from the first plunger, the first plunger disposed within the syringe cavity and defining a first chamber in the syringe cavity, wherein the first chamber is in fluid communication with the syringe port.

Abstract: Systems and methods for fully-automated contact-less biometric measurement include receiving a stream of image frames from an internet capable device. Frame data is extracted from the stream of image frames. A predictive load balancer selects a worker server based on a load prediction. An interface delivery server communicates the frame data from the internet capable device to the worker server. A set of patient face images captured by the frame data are extracted. A facial recognition machine learning model determines a patient identity associated with the set of patient face images of the frame data. A shared memory system stores the set of patient face images. The worker server determines biometric measurements based on the set of patient face images in the shared memory system using independent biometric data processing pipelines with shared access to the shared memory system for inter-process communication.

Abstract: A locking arrangement for a container that has a lid pivotally attached with a base includes a flap that is pivotally attached at a first end thereof to the lid at a peripheral edge of the lid. The flap has a tab projecting laterally away from a second end of the flap. A frangible portion of the lid is defined by a perforation that terminates to encompass the first end of the flap. A slot is formed through an upwardly-projecting peripheral wall of a base of the container. As such, with the lid of the container moving towards a closed position, and with the tab in a folded position, the flap and tab are inserted through the slot of the peripheral wall of the base, thereafter as the tab clears the slot the resilient material urges the tab into an expanded position to lock the container.
