Abstract: The present disclosure relates to systems and methods for electrically conductive membrane separation from a mixture solution via membrane nanofiltration, electro-filtration, or electro-extraction by: generating an electric field at the membrane filter, holding the membrane filter at a constant electric potential, or driving a constant current through the membrane filter; feeding a mixture solution through the membrane nanofiltration system; and separating a component from the mixture solution into a permeate solution.

Abstract: The present disclosure is directed to processes for forming or otherwise creating a transparent, conductive film from a heavy hydrocarbon material. It allows for what is often considered to be waste material to be transformed into a useful product, such as a heating element. Such heating elements can be incorporated into many contexts where it can be important to have transparency and/or a thin heating element, such as in windshields. The process involves dissolving a heavy hydrocarbon material in a solvent, casting the heavy hydrocarbon solution that results from the dissolving onto a substrate to form a film, and then annealing the film. The disclosure also provides for objects in which such resulting films can be used, such as Joule heaters.

Abstract: Systems and methods for manufacturing sintered materials are disclosed. Metal nano- and microparticles can be sintered to form thin films. The metals are sintered in the presence of a binder such as a tar, e.g., steam cracker tar (SCT), which has strong absorbing and antioxidant properties that allow the metal particles to retain heat. Retention of heat by the binder can allow the sintering to occur at ambient temperatures. In some embodiments, the mixture and/or the resulting films can be used in additive manufacturing processes to build various components from the layers of thin film manufactured from the presently disclosed methods.

Abstract: Systems and methods are disclosed for secure messaging and content sharing. In one implementation, a processor receives a content item in a first format, the content item being associated with an intended recipient, converts the content item into a second format, provides the content item, as converted into the second format, to a device associated with the intended recipient, receives, from the device associated with the intended recipient, one or more inputs in relation to a segment of the content item, processes the one or more inputs to determine that an authentication action is being performed with respect to the segment of the content item, and based on a determination that the authentication action is being performed with respect to the segment of the content item, provides an instruction to present the segment of the content item at the device associated with the intended recipient.

Abstract: Systems and methods are disclosed for secure messaging and content sharing. In one implementation, a processor receives a message associated with a recipient, provides, to the recipient, a notification pertaining to the message, and, based on a determination of a performance of one or more authentication actions with respect to the message, provides the recipient with access to the message. In another implementation, a processor receives a message including one or more content segments, receives inputs in relation to at least one of the content segments, processes the inputs to determine that an authentication action is being performed with respect to the one of the one or more content segments, and based on a determination that the authentication action is being performed with respect to the one of the one or more content segments, presents the at least one of the one or more content segments.

Abstract: The present invention provides a game for two or more players, and a method for playing the game. The game includes a game board having a plurality of spaces defining a continuous course of travel between a start space and a finish space. Each player starts on the starting space and each player takes turns using a chance device, preferably a spinner, to randomly select which one of eight arcade-style games to play to generate a number that is the number of spaces that the player must move the player's playing piece along the course of travel. The winner is the first player whose playing piece reaches the finish space.

Abstract: Systems and methods are disclosed for improving the resolution and quality of an image formed by signals from an array of receivers. Multiple receivers introduce variations in arrival times that can be less than the period of an operating signal, and also less than the period associated with a sampling operation. Thus, multiple receivers allow sampling of fine features of reflected signals that would be considered beyond the resolution associated with the operating signal. Use of multiple receivers also provides an effective sampling rate that is greater than the sampling rate of an individual receiver. Similar advantages can be obtained using multiple transmitters. Such advantageous features can be used to obtain high resolution images of objects in a medium in applications such as ultrasound imaging. Sub-Nyquist sampling is discussed. Accounting for the effects of refraction on pathlengths as a signal passes between two regions of different sound speed allows improved calculation of focus distances.
