Abstract: The techniques described herein relate to methods and systems for administering an online examination to a user. A pre-examination scan is performed based on first image data of an environment of the user that is received from a camera. Responsive to an indication from the pre-examination scan that the environment is appropriate for test taking, the online examination is initiated. The online examination is initiated by generating a user interface for display on an examination screen. Based on second image data of the user while using the user interface, one or more poses of the user may be estimated. It may be determined that the user pose is indicative of improper examination behavior based on the one or more poses of the user that are estimated. A warning can be generated and/or the online examination can be terminated based on an indication of improper examination behavior.

Abstract: The present disclosure relates, in part, to Parylene based conformal coating compositions having improved properties, e.g., improved heat transfer and durability characteristics, as well as a methods and apparatus to coat objects with these compositions, and objects coated with these compositions. In some aspects, coating compositions comprising Parylene and boron nitride are disclosed. The disclosure also includes objects (e.g., electronic equipment, textiles, etc.) having a conformal coating comprising a Parylene compound and boron nitride.

Abstract: The present invention provides a novel method to apply Silquest to an object as a vapor, a related method to coat objects with Parylene and Silquest, and objects coated by these methods. The invention further provides an vapor deposition apparatus with multi-temperature zone furnaces that is useful for applying a Parylene coating to objects. The invention further provides objects coated with Silquest and polymers, including Parylene, where the objects are incompatible with immersion in water.

Abstract: The present inventions relates to an improved and novel Parylene compositions with has improved heat transfer and durability qualities, as well as a methods and apparatus to coat objects with the novel Parylene compositions, and objects coated with the novel Parylene compositions. The novel Parylene composition of the invention comprises Parylene and boron nitride. The invention also includes objects coated with at least one polymer coat and a boron nitride coat.
