Abstract: A breathing assistance apparatus has a housing with an engagement feature and an electrical component in the housing and a removable component 171. The electrical component has a receptacle 233. The removable component 171 has an electrical connector 178 that is a close or tight fit in the receptacle 233 of the electrical component to assist with holding the removable component 171 in connection with the electrical component. The removable component has a tab 172 with a terminal end portion 172b that can be flexed relative to the rest of the removable component. An engagement feature 174 is provided on the terminal end portion of the tab and engages with the engagement feature of the housing is to inhibit disconnection of the removable component from the housing in the absence of actuating the terminal end portion 172a of the removable component to flex the tab.

Abstract: A gas turbine engine includes a turbomachine defining an engine inlet to an inlet duct, a fan duct inlet to a fan duct, and a core inlet to a core duct, a primary fan driven by the turbomachine, a secondary fan located downstream of the primary fan within the inlet duct, and a booster located downstream of the secondary fan and comprising a booster rotor blade, an inlet guide vane, and booster cowl, the booster cowl separating an upstream portion of the fan duct into an upper fan duct having an upper fan duct inlet and a lower fan duct having a lower fan duct inlet, the upper fan duct inlet and lower fan duct inlet collectively forming the fan duct inlet, the inlet guide vane located forward of the booster rotor blade.

Abstract: A transmitter system includes a mapper that maps data bits and power information to N subcarriers. A first-level modulator converts the mapped information of subcarriers into subcarrier specifications, defining their amplitude and phase (or real and imaginary amplitudes). An orthogonal subcarrier generator, for example an IFFT, calculates N successive values of baseband real and imaginary signals. A second-level modulator multiplies the baseband signals with in-phase and quadrature intermediate frequency (IF) components to generate an orthogonal IF signal. A single-sideband (SSB) prep unit may remove the lower or upper sideband. A beam former modifies the phase and/or the amplitude of the orthogonal IF signal for transmission through multiple sub-antennas in a phased array antenna.

Methods to use the bone joint inserter device in surgical procedures are also provided.

Abstract: Techniques include a calibration assembly for a telepresence system that includes a stereoscopic display and a set of cameras. The calibration assembly may include at least one chart having chart markers, a mirror having mirror markers, and a processor. An example calibration assembly has three charts and the mirror attached to one of the charts. During calibration, the display is configured to display a set of display markers that are imaged in the mirror. Each camera forms a respective image of the set of chart markers, the set of mirror markers, and the set of display markers. The processing circuitry then determines the poses of the cameras with respect to the display based on the images of the set of chart markers, the set of mirror markers, and the set of display markers.

Abstract: A hair straightening apparatus has two arms pivotably coupled at a hinge, and a central pack disposed between the first and second arms and coupled with the hair styling apparatus at the hinge on a hinge end of hair straightening apparatus. A locking mechanism is disposed within the central pack, wherein the locking mechanism includes a symmetrical, elongate lock arm disposed lengthwise within the central pack. The locking mechanism is selectively operable to lock the first and second arms in the closed position. The central pack defines a longitudinal axis, and the elongate lock arm is movable relative to the central pack between the first and second positions in parallel with the longitudinal axis defined by the central pack.

Abstract: The present document describes devices and methods for rendering multiple live-streams on a user interface (UI) with minimal resources. The UI is activated, having a first set of remote sensors loaded for rendering. The first set of remote sensors receive a first activation signal and begin streaming first data, which the UI renders. Respondent to an action changing the set of remote sensors to be rendered on the UI, a second set of remote sensors are loaded for rendering. The second set of remote sensors receive a second activation signal and begin streaming second data, which the UI renders while the first set of remote sensors continue streaming the first data. The first data is no longer streamed after a threshold time is reached.
