Multiple collimated laser beams can be arranged in a tightly packed non-overlapping array the goes through a telescope system to reduce the size of the beams and also the separation between the beam centers. The beams in the resulting smaller array then diverge until they reach a nonlinear lens, which collimates each of the beams individually so that all of the beams are collimated, pointing in the same direction and overlapping. The pulses in the beams are temporally separated from each other such that the nonlinear lens acts as a different lens for each of the beams. Such an arrangement facilitates scaling the far field average intensity by combining multiple temporally interleaved pulsed laser beams, allowing diverging pulsed laser beams to be collimated individually by utilizing the large nonlinear refractive index of certain materials.
An aircraft pilot incapacitation detection system includes a controller configured to determine, based on an input received from a flight control computer, a current flight parameter. The controller compares the current flight parameter to a corresponding predetermined flight metric associated with at least one of a predetermined flight plan or a benchmark for a predetermined flight stage. The controller determines, responsive to the comparison, that the aircraft is in an abnormal state and causes a first prompt by a user interface in communication with the controller, the first prompt being associated with a first time threshold. The controller determines whether the first time threshold is satisfied and, if so, subsequently initiates an emergency protocol and causes a second prompt associated with a second time threshold. Upon determining that the second time threshold has been satisfied, the controller carries out the emergency protocol.
Provided herein are various enhancements to spacecraft or other vehicles, including spacecraft docking mechanisms and vehicle mating systems. In one example, a vehicle mating mechanism includes a latch assembly of a vehicle having soft capture elements and hard capture elements.

The hard capture elements move within the envelope to engage the bar element and draw the bar element toward the vehicle to provide a hard capture with the mating vehicle. The vehicle mating mechanism can also include a cup-cone interface element of the vehicle that mates with a cup-cone interface element of the mating vehicle during the hard capture to establish an alignment between the vehicle and the mating vehicle.
An asymmetric, broadband, compact and low-PIM orthomode transducer comprised of two parts is presented. Mating of the two parts results in the formation of a choke flange as well as a critical impedance step which suppresses unwanted modes and enables broadband matching of the junction between the two parts.
