  • Spatial multiplexing of lens arrays with surface-emitting lasers for multi-zone illumination
    Patent number: 11022724
    Abstract: Systems, methods, and devices disclosed herein relate to optical assemblies for spatial multiplexing, multi-zone illumination, and optical assemblies. In embodiments, light source arrays are aligned with one or more micro-lens assemblies to generate a specific field of illumination. In embodiments, surface-emitting light sources may be light-emitting diodes and/or surface-emitting lasers. The micro-lens array may be aligned with the light source arrays, on-axis or off-axis to a principal axis of corresponding lenses such that the light sources may be expanded to a desired divergence and field of illumination. In embodiments, multiple light sources may be combined to increase power output for a specific area of the field of illumination, and light sources may be driven independently depending on intended illumination.

  • Fixed wireless access using orthogonal time frequency space modulation
    Patent number: 11025377
    Abstract: A fixed wireless access system is implemented using orthogonal time frequency space multiplexing (OTFS). Data transmissions to/from different devices share transmission resources using—delay Doppler multiplexing, time-frequency multiplexing, multiplexing at stream and/or layer level, and angular multiplexing. Time-frequency multiplexing is achieved by dividing the time-frequency plan into subgrids, with the subsampled time frequency grid being used to carry the OTFS data. Antenna implementations include a hemispherical antenna with multiple antenna elements arranged in an array to achieve multiplexing.

  • Setup automation for respiratory treatment apparatus
    Patent number: 11020552
    Abstract: A respiratory treatment apparatus implements pressure delivery control settings by improved set-up procedures. In such an embodiment, a processor may automate setting of parameters for delivering a controlled flow of breathable gas. Data sets of pressure delivery parameter settings may be associated with one or more respiratory pathology indicators. The respiratory pathology indicators may each represent a different respiratory condition diagnosis. The processor may then prompt for an input of at least one of the respiratory pathology indicators. In response to the input, a particular set of pressure delivery parameter settings associated with the input respiratory pathology indicator may then serve as a basis for setting controls for delivering a controlled flow of breathable gas for respiratory treatment.

  • Multiple camera apparatus and method for synchronized autofocus
    Patent number: 11022858
    Abstract: A disclosed apparatus includes a plurality of camera units. Control logic, operatively coupled to each camera unit, is operative to perform a parallax operation using at least two image frames from at least two camera units to determine a common focus distance, subsequent to completing independent auto-focus operations and respective lens position adjustments for the at least two camera units. The control logic provides a control signal to at least one of the camera units to adjust its actuator to adjust lens position in response to the determined common focus distance. A test procedure is used to map focus distance to lens position for each camera unit and to generate a lookup table. The control logic uses the lookup table unique to each camera unit to adjust the lens settings according to the determined common focus distance. The parallax operation is iterated until the common focus distance converges.

  • Devices and methods for sample analysis
    Patent number: 11022598
    Abstract: Methods, devices, and systems for analyte analysis using a nanopore are disclosed. The methods, devices, and systems utilize a first and a second binding member that each specifically bind to an analyte in a biological sample. The method further includes detecting and/or counting a cleavable tag attached to the second binding member and correlating the presence and/or the number of tags to presence and/or concentration of the analyte. Certain aspects of the methods do not involve a tag, rather the second binding member may be directly detected/quantitated. The detecting and/or counting may be performed by translocating the tag/second binding member through a nanopore. Devices and systems that are programmed to carry out the disclosed methods are also provided.

  • Laminar flow radial ceiling fan
    Patent number: 11022127
    Abstract: The prior art has used pitched blades attached to a stationary motor, normally electric. to move air within the confines of a structure or room. The preferred invention incorporates a series of solid discs. The discs are affixed to a stationary electric motor and thus rotate around a central axis. The discs are equally spaced and centrally perforated in a manner that will allow air to flow in high volumes through the perforations and pass along the discs thus exiting symmetrically between each disc perpendicularly to the flow of air that is at its entrance. Due to the less restrictive or low pressure air entrance as well as the correct vertical disc spacing a corresponding increase in the laminar flow is realized. This feature of the preferred invention allows for operation at a rotational speed that practical for use as a ceiling fan.
