Abstract: An imaging system comprises a wide field of view (FOV) telescope, a narrow FOV telescope, a spectrometer, an imaging detector, an image slicer, and a selection mechanism. The wide FOV telescope is configured to produce a one-dimensional optical image of a broad field of view (FOV) F. The narrow FOV telescope is configured to produce a two-dimensional optical image of a narrow FOV f. The spectrometer is configured to produce a spectrum of a one-dimensional image, and the imaging detector is configured to capture that spectrum. The image slicer is configured to break the two-dimensional optical image into a series of one-dimensional segments. The selection mechanism operable in either of two modes: a wide FOV mode transmitting the one-dimensional optical image to the spectrometer, and a zoom mode transmitting a one-dimensional concatenation of the series of one-dimensional segments to the spectrometer.

Abstract: An ion trap comprises a ring electrode and opposite first and second endcap electrodes situated at opposite ends of the ring electrode. A waveform generator is configured to vary both frequency and amplitude of an AC waveform applied across the first and second endcap electrodes as a function of time, thereby exciting ions with a band of resonant secular frequencies substantially without exciting ions with adjacent secular frequencies.

Abstract: A diagnostic device identifies failed sub-modules within a larger system based on error codes received from the system. The device stores a likelihood matrix that correlates each sub-module with each possible error code and maintains a likelihood value corresponding to the probability of a failed sub-module generating a corresponding error code and stores a prior probability of failure associated with each sub-module based on prior observational data. In response to received error codes, the device calculates a posterior probability of failure for each of the plurality of sub-modules based on a product of the likelihood values corresponding to the received error codes and the prior probability of failure associated with each sub-module. Based on the calculated posterior probability, the device identifies the sub-module with the highest posterior probability of failure as the failed sub-module.

Abstract: An example space-based power generation panel arrangement includes a first reflective panel and at least one heat pipe configured to communicate thermal energy to the first reflective panel and a second reflective panel. The heat pipe is configured to hinge the first reflective panel to the second reflective panel.

Abstract: A system comprises first and second Fresnel reflectors. Each of the Fresnel reflectors comprises a Fresnel surface with a focus, a radiating surface opposite the Fresnel surface, and a photovoltaic element mounted to the Fresnel surface, in thermally conducting contact with the radiating surface. The first and second Fresnel reflectors form a vertex having a dihedral angle, such that the focus of the first Fresnel reflector is directed toward the photovoltaic element on the second Fresnel reflector, and such that the focus of the second Fresnel reflector is directed toward the photovoltaic element on the first Fresnel reflector.
