Abstract: Herein provided are methods and systems for controlling an engine having a variable geometry mechanism. A pressure ratio between a first pressure at an inlet of the engine and a predetermined reference pressure is determined. An output power for the engine is determined. The output power is adjusted based at least in part on the pressure ratio to obtain a corrected output power. A position control signal for a variable geometry mechanism of the engine is generated based on the corrected output power and the pressure ratio. The position control signal is output to a controller of the engine to control the variable geometry mechanism.

Abstract: A nasal seal, mask or an interface assembly have a seal body defining a breathing chamber. A nasal port is provided in the seal body. The nasal port has a central portion straddled by a pair of lateral portions. The nasal port further has an upper edge and a lower edge. The upper edge defines an inwardly projecting portion within the central portion. The lower edge defines an inwardly protection portion within the central portion. Thus, the nasal port can be generally bean-shaped or bowtie-shaped. The mask can include a frame having a central portion that supports the seal and a pair of arm portions that extend rearwardly of the seal and are configured to connect to headgear. The central portion can be more rigid than the arm portions. The mask can be configured to reduce noise transmitted through a bias flow vent.

Abstract: Circuit assemblies can be electrically interconnected by providing a circuit assembly having a top surface, a bottom surface, and a perimeter edge connecting the top and bottom surfaces, the perimeter edge being formed of insulative material and having a plurality of conductive features embedded in and exposed on the surface of the edge. The conductive features are arranged in contact sets, and each contact set is separated from adjacent contact sets by a portion of the perimeter edge that is free of conductive features. Each contact set includes conductive features that together form a distributed electrical connection to a single node. The insulative material is selectively removed to form recesses adjacent the conductive features exposing additional surface contact areas along lateral portions of the conductive features in the recesses.

A blinker module, rearview device and motor vehicle, including the blinker module manufactured according to the method, are also described.

Abstract: Interfaces for positive pressure therapy having various vent designs are disclosed herein. The interfaces include a bias flow vent with design geometries that help reduce and/or minimize draft and noise levels of the fluids exiting the vents. Some of the vent designs include particular vent hole geometries, plenum spaces, diffusers and fibrous media.

Abstract: A lottery ticket dispenser array includes a plurality of interconnected bins, wherein the bins include a housing having a bottom and an open top. A drawer is slidable into and out of the housing and includes an open top and a ticket compartment configured for receipt of a stack of the interconnected lottery tickets in a laid-down orientation. A component section adjacent in the drawer is configured to automatically dispense the lottery tickets through a dispense slot upon receipt of a dispense command. A ramp is disposed within the ticket compartment and is angled upwards from a floor of the ticket compartment towards the component section. The ramp includes a plurality of raised ridges extending across the ramp and spaced longitudinally apart along the ramp, wherein each ridge defines a retaining edge for progressively longer stacks of interconnected lottery tickets placed within the ticket compartment in the laid-down orientation.

Abstract: A lottery ticket dispenser array includes a plurality of interconnected bins, wherein the bins include a housing having a bottom and an open top. A drawer is slidable into and out of the housing and includes an open top and a ticket compartment configured for receipt of a stack of the interconnected lottery tickets. A component section adjacent in the drawer is configured to automatically dispense the lottery tickets through a dispense slot upon receipt of a dispense command. Spaced-apart ticket guides are configured on an outer side of the bin bottom so as to extend through the open top and into the ticket compartment of the adjacent lower bin in the array. The ticket guides are configured to engage along at least side edges of the interconnected lottery tickets as they are dispensed or retracted relative to the ticket compartment.

Abstract: Provided herein are systems and methods for implementing a network consensus for a blockchain network that is characterized by one or more, or all, of the following attributes: (1) implementation of a Proof-of-Coverage scheme; (2) lack of permission for nodes to participate in the network; (3) decentralization, with lack of incentives to centralize; (4) byzantine fault tolerance; (5) based on useful work to the network; (6) high confirmed transaction rate; and (7) censor-resistant transactions.

Abstract: A lottery ticket dispenser array includes a plurality of separate bins, each bin having a housing with a back side. A circuit board fixed to the back side of the housing to supply power and control functions to the bin. The circuit boards of adjacent bins are rigidly interconnected via complimentary electronic connectors. At each bin, the circuit board is mounted to the back side of the housing with a defined relative degree of movement between the circuit board and the housing in at least a first direction. The rigidly interconnected circuit boards define a rigid structure and one or more of the bins are movable relative to the rigid structure such that the array absorbs misalignment, movement, and size variations between the bins without disconnection of the electronic connectors between the bins.
