    Abstract: A dynamic, thermally-adaptive cuboid laser crystal mount is provided that is suitable for use with end-pumped, conductively-cooled solid state lasers. Various embodiments may provide a mount for supporting a cuboid rod host crystal for an end-pumping solid state laser. Various embodiments may solve laser crystal stress problems typically experienced in end-pumped solid state lasers. Various embodiments may also provide access to the crystal end surfaces for pumping and enable and maintain sturdy alignment of the crystal with continuous and uniform surface contact between the mount and the crystal. Various embodiments of mounts may provide a compact conductive cooling configuration compatible with any heat sink reservoir, controlling and maintaining a stable crystal temperature, thus avoiding thermally induced mechanical stresses. Various embodiment mounts may thereby further extend the fracture threshold of the laser crystal.

  • Patent number: 12022172
    Abstract: A multi-spectral imaging system utilizing tunable optics is disclosed. Various disclosed systems include a tunable optical filter coupled to a broadband imaging system. The tunable optical filter allows discrete infrared wavelengths to pass to the broadband imaging system so that monochromatic infrared images of a scene may be captured. An image processing system may process selected monochromatic infrared images by using a ratio technique to generate an emissivity-independent thermal image of the scene. The tunable optical filter may also be used to adjust a quality factor and control an amount of radiated energy that is passed to an image sensor of the broadband imaging system thereby acting as an aperture to account for both low and high radiance portions of the scene.

  • Patent number: 12003951
    Abstract: A statistical audibility prediction (SAP) method for predicting the audibility of a signal over time at a listening location, the signal from a signal source in the presence of a concurrent masking sound or masker from a masker source. The method includes receiving, via a processor over a plurality of auditory channels, a specific loudness of the signal and masker at the listening location. The method includes calculating for each auditory channel a standard deviation of a distribution of the specific loudness of the signal and masker, and calculating, via the processor, corresponding channel-specific detectability indices (d?t,i) for each auditory channel as a function of their standard deviations. The corresponding channel-specific detectability indices are then summed to produce a total detectability index (d?t), which may be output as an electronic signal that indicates the predicted audibility vs. time, e.g., to a downstream process and/or system or offline.

  • Patent number: 11980100
    Abstract: A metal junction thermoelectric device includes at least one thermoelectric element. The thermoelectric element has first and second opposite sides, and a first conductor made from a first metal, and a second conductor made from a second metal. The first and second conductors are electrically interconnected in series, and the first and second conductors are arranged to conduct heat in parallel between the first and second sides. The first metal has a first occupancy state, and the second metal has a second occupancy state that is lower than the first occupancy state. A temperature difference between the first and second sides of the thermoelectric element causes a charge potential due to the difference in occupancy states of the first and second metals. The charge potential generates electrical power.

  • Patent number: 11970586
    Abstract: A composite material may be prepared from a solid polymeric binder and a solid filler by feeding into an extruder the solid polymeric binder at a first feed rate and the solid filler at a second feed rate. The extruder extrudes an extrudate of the solid polymeric binder and solid filler to form the composite material. The composite material has a binder to filler ratio determined by the first feed rate and second feed rate. The solid polymeric binder and solid filler have different densities. Feeding the solid polymeric binder at the first feed rate and the solid filler at the second feed rate distributes the solid filler substantially homogeneously throughout the composite material.

  • Patent number: 11903719
    Abstract: A method of providing physiological self-regulation challenges prior to participating in a series of activities or exercises at a series of predefined locations includes determining a physiological goal associated with each location. A sensing device measures a physiological state of a user, and a mobile communication device communicates to a user whether or not the user has achieved the physiological goal for the challenge. The level of difficulty of the physiological goal may be reduced if the user does not meet the goal. The physiological goal may comprise a brain state that is conducive to learning, and the sensing device may be configured to measure brain state values representing cognitive engagement. Upon achievement of each physiological goal, the participant is provided with a reward such as information concerning the current predefined location and/or information concerning the next predefined location.
