  • Patent number: 11794149
    Abstract: A filtration membrane coating comprising a hydrophilic polymer, a surfactant, and one or more charged compounds, each containing one or more sulfonate functionalities and one or more linkable functionalities selected from the group consisting of amine, monochlorotriazine, and dichlorotriazine. The hydrophilic polymer and surfactant form a thin primer layer which is also superhydrophilic. The primer layer improves flux, and enables improved adhesion of the one or more charged compounds, which form a charged dye layer on top of the primer layer when enhances rejection of charged divalent ions. The coating can be applied while the membrane is packaged in its final form, such as in a spiral wound or other configuration.

  • Patent number: 11672676
    Abstract: A brain machine interface system for use with an electroencephalogram to identify a behavioral intent of a person is disclosed. The system includes an electroencephalogram configured to sense electromagnetic signals generated by a brain of a person. The electromagnetic signals include a time component and a frequency component. A monitor monitors a response of the person to a stimulus and a characteristic of the stimulus. A synchronization module synchronizes the sensed electromagnetic signals with the response and the characteristic to determine a set of electromagnetic signals corresponding to the monitored response and the characteristic. A processor processes the set of electromagnetic signals and extracts feature vectors. The feature vectors define a class of behavioral intent. The processor determines the behavioral intent of the person based on the feature vectors. A brain machine interface and a method for identifying a behavioral intent of a person is also disclosed.

  • Patent number: 11605722
    Abstract: An ohmic contact for a multiple channel FET comprises a plurality of slit-shaped recesses in a wafer on which a multiple channel FET resides, with each recess having a depth at least equal to the depth of the lowermost channel layer. Ohmic metals in and on the sidewalls of each recess provide ohmic contact to each of the multiple channel layers. An ohmic metal-filled linear connecting recess contiguous with the outside edge of each recess may be provided, as well as an ohmic metal contact layer on the top surface of the wafer over and in contact with the ohmic metals in each of the recesses. The present ohmic contact typically serves as a source and/or drain contact for the multiple channel FET. Also described is the use of a regrown material to make ohmic contact with multiple channels, with the regrown material preferably having a corrugated structure.

  • Patent number: 11598878
    Abstract: A vision-cued random-access LIDAR system and method which determines the location and/or navigation path of a moving platform. A vision system on a moving platform identifies a region of interest. The system classifies objects within the region of interest, and directs random-access LIDAR to ping one or more of the classified objects. The platform is located in three dimensions using data from the vision system and LIDAR. The steps of classifying, directing, and locating are preferably performed continuously while the platform is moving and/or the vision system's field-of-view (FOV) is changing. Objects are preferably classified using at least one smart-vision algorithm, such as a machine-learning algorithm.

    Abstract: A single crystal multilayer low-loss optical component including first and second layers made from dissimilar materials, with the materials including the first layer lattice-matched to the materials including the second layer. The first and second layers are grown epitaxially in pairs on a growth substrate to which the materials of the first layer are also lattice-matched, such that a single crystal multilayer optical component is formed. The optical component may further include a second substrate to which the layer pairs are wafer bonded after being removed from the growth substrate.

  • Patent number: 11581355
    Abstract: A curved FPA comprises an array of detectors, with mesas etched between the detectors such that they are electrically and physically isolated from each other. Metallization deposited at the bottom of the mesas reconnects the detectors electrically and thereby provides a common ground between them. Strain induced by bending the FPA into a curved shape is across the metallization and any backfill epoxy, rather than across the detectors. Indium bumps are evaporated onto respective detectors for connection to a readout integrated circuit (ROIC). An ROIC coupled to the detectors is preferably thinned, and the backside of the ROIC may also include mesas such that the ROIC is reticulated.

  • Patent number: 11575020
    Abstract: A method of forming a bipolar transistor with a vertical collector contact requires providing a transistor comprising a plurality of epitaxial semiconductor layers on a first substrate, and providing a host substrate. A metal collector contact is patterned on the top surface of the host substrate, and the plurality of epitaxial semiconductor layers is transferred from the first substrate onto the metal collector contact on the host substrate. The first substrate is suitably the growth substrate for the plurality of epitaxial semiconductor layers. The host substrate preferably has a higher thermal conductivity than does the first substrate, which improves the heat dissipation characteristics of the transistor and allows it to operate at higher power densities. A plurality of transistors may be transferred onto a common host substrate to form a multi-finger transistor.

  • Patent number: 11215867
    Abstract: A multi-spectral lens comprises a circular polarizer and a tunable cholesteric filter having an associated reflection band. Incoming light is circularly polarized to one handedness by the circular polarizer, and the tunable cholesteric filter transmits the circularly polarized light and reflects the opposite handedness of the circularly polarized light if within the reflection band of the filter, with the reflection band of the tunable cholesteric filter varying with a control voltage. In a preferred embodiment, a mirror is arranged to receive light transmitted by the tunable cholesteric filter and reflect it back towards the filter with flipped handedness, with the reflected light with flipped handedness that is within the reflection band of the tunable cholesteric filter reflected by the tunable cholesteric filter back toward the mirror. The architecture described effectively converts the reflection band of a tunable cholesteric filter into a tunable bandpass filter for a multi-spectral imaging lens.

  • Patent number: 11118982
    Abstract: A semiconductor material emitting device is positioned such that its output flux impinges on a substrate at a non-perpendicular angle, so as to grow a first epilayer which is linearly graded in the direction perpendicular to the growth direction. The linear grading can be arranged such that, for example, each row of pixels has a different cutoff wavelength, thereby making it possible to provide a spectroscopic FPA without the use of filters. The non-perpendicular angle and/or the flux intensity can be adjusted to achieve a desired compositional grading. A spectral ellipsometer may be used to monitor the composition of the epilayer during the fabrication process, and to control the intensity of the flux.
