  • Patent number: 10705203
    Abstract: The present disclosure provides systems and methods associated with an antenna system comprising a tension member configured to be towed by an aerial platform. In some embodiments, a first end of the tension member may be secured to the aerial platform and the second end may extend unsecured from the aerial platform at a different elevation than the first end. A plurality of antenna assemblies, each comprising at least one antenna, may be secured to and spaced along the length of the tension member. Each of the plurality of antennas may be adapted for use with a particular frequency or frequency bandwidth. For example, each of the plurality of antennas may be adapted or tuned for one or more frequencies useful for synthetic aperture radar (SAR). In some embodiments, a receiving system, a communication link, and/or an antenna location system may be utilized.

  • Patent number: 10655883
    Abstract: A system and associated methods of operation for regulating an environmental variable (such as ambient room temperature) within a target zone. The system includes an occupancy sensor configured to monitor the target zone and determine a number of inhabitants present within the zone. The occupancy sensor generates an occupancy signal communicating the number of detected inhabitants to an environmental control system. Upon receiving the occupancy signal, the environmental control system regulates an environmental variable within the zone based on the number of inhabitants present in the zone.

  • Publication number: 20200040191
    Abstract: Novel, nano-structured particles are formed by introducing a selected solid of interest into a structured fluid matrix formed by a dispersion of a small molecule host vessel components, such as a native or modified polysaccharide, cavitand, simple sugar, disaccharide, simple polyol or other similarly structured molecule known to be useful as a host vessel, in an acidic medium or other solvent, whereby the particle size of the introduced solid is reduced and or limited in the structured fluid matrix, by incorporation into or attachment to, the host vessel. The simple, one-batch mixing process results in stabilized colloidal dispersions of the nanoparticles of a variety of solids of varying scope and function and useful in a wide variety of applications, including without limitation ceramic materials, such as hexagonal boron nitride.

  • Patent number: 10449445
    Abstract: An electronic game feedback system includes a display device, a sensor system, and a feedback device. The display device is configured to provide a display of a virtual environment associated with an electronic game to a user. The display device at least partially obstructs the view of the user of a physical environment surrounding the user. The sensor system is configured to acquire object data regarding an object located within the physical environment. The feedback device is configured to provide feedback to the user based on the object data and indicative of a location of the object relative to the user.
