The assembly further includes a fluid flow path configured such that, when the securing member mounts the infant feeding nipple to the container in use, the container is fluidly connected to the surface. A method of sterilising the infant feeding assembly is also disclosed.

Abstract: There are described various embodiments for devices, systems, and methods for security threat detection and reaction using multi-layered decentralized federated learning approach, for use in various combinations of security systems, including facial recognition systems, biometric recognition systems, gesture recognition systems, voice recognition systems, network traffic pattern monitoring systems, security systems using Internet of Things (IoT) sensors, and home automation security systems. By combining federated learning system with a local interpretation layer, it is possible for each local node in a system to interpret anonymized federated learning results into highly personalized results, which can then be used to trigger highly personalized actions. The multi-layered federated learning threat detection and response system therefore optimizes for both enhanced privacy and customization.

Abstract: A nipple for attachment to an external component, for example a container. The nipple comprises a base portion for attachment to the external component. The nipple also comprises a breast portion extending from the base portion. The nipple also comprises an areola portion extending from the breast portion. The nipple also comprises a teat portion extending from the areola portion. The breast portion extends at a first angle relative to an axis of the base portion and the areola portion extends at a second angle relative to the axis of the base portion, wherein the first angle is greater than the second angle.

Abstract: Apparatus for forming wooden members used to assemble wooden trusses includes a control computer receiving a batch list identifying each member included in each trusses. A first conveyor transports wooden members from an infeed chute to a finger-jointer joining wooden members end-to-end. A saw cuts the joined wood, and a second conveyor transports cut wooden members past a face printer for printing a component identifier on the face of such member, and past an edge printer for printing identifying assembled truss information upon an edge of selected members. A sensor detecting a member approaching the printers provides a signal to the control computer to synchronize printing by the face printer and to synchronize printing by the edge printer. The face printer and edge printer may be oriented perpendicular to each other. A related method is also disclosed.

Abstract: Coffee makers with features for rapid and/or multiple extraction processes, and associated systems and methods, are included. A representative method for brewing coffee includes placing ground coffee on a filter element of a brew chamber, directing heated water into the brew chamber and in contact with the ground coffee and, during a first phase, brewing coffee in the brew chamber without subjecting the coffee to a pressure differential of at least 150 torr between the brew chamber and a coffee chamber to which the brew chamber is coupled, the coffee chamber having a capacity of 200 mL or more. The representative method further includes, during a second phase, extracting the coffee from the brew chamber through the filter element and into the coffee chamber via a pressure differential of at least 150 torr between the brew chamber and the coffee chamber.

Abstract: A beverage dispenser and/or dispenser system including an airpot, a tilt sensor, and a controller are disclosed herein. In a representative example, the airpot includes a vessel used to contain coffee or another brewed/steeped beverage. The airpot can further include a liquid level sensor positioned to detect a liquid level within the vessel. The tilt sensor and the controller can be carried by the airpot. The controller is operably coupled with the liquid level sensor and the tilt sensor and has a computer-readable medium carrying instructions that, when executed, cause the controller to (i) receive, from the liquid level sensor, a first signal corresponding to a first liquid level, (ii) determine, in response to a signal from the tilt sensor, the occurrence of an inversion event, (iii) receive, from the liquid level sensor, a second signal corresponding to a second liquid level, and (iv) determine a liquid level change based on the first and the second signals.

Abstract: A system, method, or apparatus for towing that allows for illumination of a tow rope and/or other components of a towing system or apparatus. The illumination can be achieved through the use of light sources that are coupled to a power source. A tow rope having a length, and a portion of that length can have a strip comprising at least one light source. The strip is of a length that is less than the length of rope and coupled to a control system allows for coupling to the at least one light source. A set of protective layers can surround the strip, engaging the strip with the length of rope, and to prevent the strip from breaking when flexed with the rope. In some examples, the rope can have a first end having a loop, and second end coupled with a handle.
