Abstract: Discussed herein are devices, systems, and methods for determining whether to conduct a mission. A method can include partitioning, by processing circuitry configured to implement a model for determining a value representing a probability that operation of an electronic part of a device will be upset by a single event effect (SEE), a trajectory of the device into disjoint time segments. The method can include determining, based on an effective shielding of the device and one or more flux lookup tables (LUTs) for each of the time segments, respective SEE rates experienced by the electronic part for each time segment. The method can include determining, based on the determined respective SEE rates and using the model, the probability. The method can include permitting the device to traverse the trajectory only if the determined probability is less than a specified threshold.

Abstract: A HVACR protection system can include a pressure sensor to sense pressure within a refrigerant line coupled to a compressor; a timer; and a protection system controller. A compressor controller in communication with the protection system controller can control operation of the compressor and disable the compressor until successful completion of a vacuum test of the refrigerant line. The vacuum test can initiate upon the pressure sensor sensing the pressure being less than or equal to a vacuum test pressure, at which point the timer begins timing for a vacuum test time period. The vacuum test is successfully completed upon expiration of the vacuum test time period with the pressure remaining less than or equal to the vacuum test pressure for the vacuum test time period. The protection system controller can enable the compressor controller to operate the compressor upon successful completion of the vacuum test.

Abstract: A method includes providing outgoing optical signals for transmission by a monostatic optical terminal using multiple transmit channels and providing incoming optical signals obtained by the monostatic optical terminal to multiple receive channels. The method also includes using a polarization beam splitter/combiner to combine the outgoing optical signals into a combined outgoing optical signal and to split a combined incoming optical signal into the incoming optical signals. The method further includes using at least one feedback loop to adjust an aim or path of at least one of the outgoing optical signals or at least one of the incoming optical signals. The method may optionally include using an optical element to convert polarizations of the combined outgoing optical signal in order to generate an output signal and to convert polarizations of an input signal in order to generate the combined incoming optical signal.

Abstract: A zoom system includes a collection optic L1 and a reflective Fresnel Lens L2 having a variable focal length. The reflective Fresnel Lens L2 is implemented with a MEMS MMA in which the mirrors tip, tilt and piston form and alter the reflective Fresnel Lens to focus light at a common focal point to set the variable focal length f2, hence the magnification M. In different embodiments, the zoom system may be configured to be “focal” or “afocal”. In the focal system, both L1 and L2 are fixed such that the system affects the net convergence or divergence of the magnified beam. In an afocal system, a mechanism is used to translate L2 to maintain a separation between L1 and L2 of d=f1+f2 as f2 is varied to change the magnification M.

Abstract: Techniques and methods related to a multi-mode operation of a synchronous electrical generator. The synchronous generator is configurable in at least two modes: a grid-power mode and a power-generation mode. In the power-generation mode, electrical power is generated in response to power produced by a prime mover. In the grid-power mode, the rotor is in standstill mode, and the configurable rotor winding is configured to generate a plurality of AC magnetic fields. The system provides for seamless transfer of power between grid-power to power generation using an energy storage unit and associated power conditioning apparatus.

Abstract: A universal payload manipulation tool employs a segmented ring captured in a telescoping cradle to perform the positioning functions of both a workstation and a loading adapter. The ring rotates over a range of 360 degrees to perform the position functions of the workstation. With the upper ring segment removed, the telescoping cradle rotates and the lower ring segment rotates and extends from the telescoping cradle over a combined range of rotation to position the payload at a specified angle for unloading to perform the position functions of a loading adapter. This configuration allows the universal tool to access confined spaces while supporting a range of rotation required in many applications for unloading the payload (loading the payload to another platform such as an aircraft). The manipulation tool may also be configured as only a loading adapter.
