Abstract: Certain aspects relate to systems and techniques for medical instrument navigation and targeting. In one aspect, a system includes a medical instrument having an elongate body and at least one sensor, a display, a processor, and a memory storing a model of a mapped portion of a luminal network and a position of a target with respect to the model. The processor may be configured to: determine, based on data from the at least one sensor, a position and orientation of a distal end of the medical instrument with respect to the model, and cause, on at least a portion of the display, a rendering of the model, the position of the target, and the position and orientation of the distal end of the medical instrument. The rendering may be based on a viewpoint directed at the target and different from a viewpoint of the medical instrument.

Abstract: Embodiments of the present disclosure are directed to techniques for transitioning a spacecraft from a power-saving state to a power-consuming state at a time after launch of the spacecraft on a launch vehicle. Because the spacecraft can detect conditions for transitioning to the power-consuming state, commands received via an umbilical connection to the launch vehicle, or detecting the presence or absence of such a connection, is unnecessary, thereby removing several technical barriers to eliminating such umbilical connections altogether.

Abstract: Embodiments of the present disclosure are directed to techniques for autonomously transitioning a spacecraft from a power-saving state to a power-consuming state at a time after launch of the spacecraft on a launch vehicle. Because the spacecraft can autonomously detect conditions for transitioning to the power-consuming state, commands received via an umbilical connection to the launch vehicle, or detecting the presence or absence of such a connection, is unnecessary, thereby removing several technical barriers to eliminating such umbilical connections altogether. In some embodiments, low-cost vacuum detection devices that use very small amounts of power may be used by the spacecraft to detect when the spacecraft has reached an altitude suitable for transitioning to the power-consuming state.

Abstract: Disclosed is an apparatus and method for a slide and tilt hinge mechanism. The slide and tilt mechanism comprises an upper element (102) having a top (140) and a bottom (132) and an angled (130) portion located at an end (144) of the upper element, the angled portion angled relative to the top and the bottom of the upper element. A lower element (104) having a first lower element portion (122) and a second lower element portion (124) coupled together by a joint (126), the joint allowing the first lower element portion to fold relative to the second lower element portion and the upper element. A slide enabling member (302/304), coupling the upper element to the lower element such that when the upper element and the lower element are in a closed configuration (100), the upper element prevents the lower element from folding. A biasing member (128), biasing the lower element to fold about the joint when the upper element is slid to an extended position.

Abstract: Fluoroalkanes such as fluoromethane labeled with 17F are produced by contacting 17F labeled F2 with alkanes, preferably methane, substituted or unsubstituted alkenes, or substituted or unsubstituted alkynes in the presence of a metal oxide catalyst, preferably a silver oxide catalyst, to produce the 17F labeled fluoroalkane. The 17F may be produced by irradiating 20Ne with protons, preferably having an energy of about 11 MeV and produced by a cyclotron. The 17F labeled fluoromethane or fluoroalkanes may be produced continuously. A method for determining the location of an 17F labeled tracer includes generating an 17F labeled fluoroalkane, administering the 17F labeled fluoroalkane to a test subject, and scanning the test subject with a radiosensitive detector such as a positron emission tomography scanner.
