Abstract: An intra-uterine device for treating post-partum hemorrhage (PPH) is described, along with an applicator system. In embodiments, the PPH device is comprised of a mesh pouch that is filled with a plurality of sponges. Each sponge is designed to expand upon absorption of fluids, such as blood. The collective expansion of the sponges within the mesh pouch causes the PPH device to expand within a patient's uterus, thus applying pressure to stanch blood flow. The PPH device is loaded into an applicator which is then inserted into a patient, and a corresponding plunger is used to deploy the PPH device. Following completion of treatment, the PPH device may be removed using a removal strand attached to the pouch that is exposed outside of the patient.

Abstract: According to certain examples a spectrometer module for use in an imaging spectrometer includes a monolithic spectrometer body component made of an immersion material and including three mirrored surfaces configured to form a reflective triplet having an optical path immersed within the immersion material, the reflective triplet configured to receive incident optical radiation from an entrance face of the monolithic spectrometer body component and reflect the incident optical radiation along the optical path, and a dispersive element configured to receive and disperse the incident optical radiation reflected from the reflective triplet to provide dispersed optical radiation. The reflective triplet is configured to receive the dispersed optical radiation from the dispersive element and to reflect the dispersed optical radiation along the optical path to an exit face of the monolithic spectrometer body component.

Abstract: A calibration system for calibrating a tilt angle of the fast steering mirror includes a position sensing device configured to generate a beam of electromagnetic radiation, and a diffractive optical element, positioned between the position sensing device and the fast steering mirror, the diffractive optical element being configured to divide the input beam into a plurality of output beams directed to the fast steering mirror. The position sensing device is configured to determine a tilt angle of the fast steering mirror. A method to calibrate a tilt angle of the fast steering mirror is further disclosed.
