Abstract: A bone fixation device includes a plastically deformable bone fixation body having a screw receiving aperture extending therethrough. The shape of the aperture is defined by a side wall having a first threaded portion, a second smooth walled portion extending from the first threaded portion, and a third smooth walled portion extending from the second portion. The aperture has a step change in cross section between the second and third portions defining a lip. The second and third portions are connected by a lip face extending substantially normal to the aperture length with the edge of the lip face defining the lip. The device further includes at least one bone fixation screw having a shaft and a head. The shaft engages with the first threaded portion of the aperture and the head abuts the lip with an abutment force being directed substantially radially outwards so producing a tight fit.

Abstract: In a wireless communication network, index circuitry transfers a reference Distributed Ledger (DL) request to reference circuitry. The reference circuitry transfers a response indicating a reference DL ID to the index circuitry. The index circuitry transfers the reference DL ID to the wireless communication network. The reference circuitry receives usage data and the reference DL ID from the wireless communication network. The reference circuitry stores the usage data in reference DL blocks, generates a usage abstraction of the usage data, and transfers the reference DL ID and the usage abstraction to the index circuitry. The index circuitry stores the usage abstraction and the reference DL ID in index DL blocks. The index circuitry receives requests having the reference DL ID and returns the usage abstraction. The reference circuitry receives requests having the reference DL ID and usage abstraction ID and returns the usage data.

Abstract: A respiatory mask includes a frame and a cushion module. The frame can include a front wall having a vent and/or a gas inlet opening and a collar extending away from the front wall. The collar surrounds the vent and/or the gas inlet opening. The cushion module comprises a cushion and a housing, which is made of a material more rigid than the cushion. The housing defines a connection opening. A friction coupling selectively couples the cushion module to the frame and comprises an elastomeric friction member coupled to a portion of the housing that defines the connection opening. In some arrangements, an outer surface of the friction member is exposed when the cushion module is coupled to the frame. In some arrangements, the housing extends through the peripheral surface.

Abstract: In some examples, a computing device may receive stylus sensor data from one or more sensors in a stylus that is used to interact with the computing device. The computing device may determine, based on the stylus sensor data, (i) a stylus height of a tip of the stylus from a display device and (ii) one or more stylus angles of the stylus relative to the display device. The computing device may display, on the display device, a virtual shadow of the stylus at a location based at least in part on the stylus height, the stylus angles, and a location of a virtual light source. The computing device may display, on the display device, one or more virtual shadows of content items corresponding to the stylus acting as a virtual light source.

Abstract: Apparatus and associated methods relate to a networked system having a master and multiple slaves, where each slave stores a unique (actual) slave address and a non-unique (virtual) slave address in memory, such that each slave is configured to respond to request messages addressed to the slave's non-unique slave address if a sensor device associated with the is in an active state when the slave receives the request message. In an illustrative example, the networked system may be a Fieldbus-style network (e.g., a network implementing the Modbus protocol). A sensor device may be a break-beam, capacitive touch, or push-button device, for example. An output indicator/actuator may be associated with a sensor device to indicate the status of the sensor device to a user. A networked system implementing sensor-activated response gating may beneficially expand the number of slave devices on the network while achieving low latency response times.
