Abstract: Media, methods, and systems are provided for screen sharing. A user may initiate a video recording. A recording preview interface may be displayed for the user to preview the video recording before beginning the recording. The recording preview interface may comprise a live video preview of the user and of a window or application being shared. When the user selects a window or application for previewing that may cause an infinity mirror effect to occur, a screenshot of the window or application may be generated. The screenshot may be rendered over the live video preview of the window or application to obscure the infinity mirror effect. When the user initiates recording, the screenshot may be removed to expose the live video. The screenshot may be cached and retrieved if the user navigates away and then returns to the preview of the window or application causing the infinity mirror effect.

Abstract: The disclosure features methods that include obtaining a vibrational spectrum of a solution in a biological manufacturing system, analyzing the vibrational spectrum using a first chemometrics model to determine a value of a first quality attribute associated with the solution, analyzing the vibrational spectrum using a second chemometrics model to determine a value of a second quality attribute associated with the solution, and adjusting at least one parameter of a purification unit of the biological manufacturing system based on at least one of the values of the first and second quality attributes.

Abstract: A temperature controlled therapeutic plush toy assembly is disclosed. The plush toy has a body, a thermal block contained within the body, and temperature retaining materials contained within the body. The thermal block can hold either hot or cold temperatures. The temperature of the thermal block can be modified by either placing the plush toy in the microwave or placing the plush toy in the freezer. The temperature retaining materials provide insulation to the thermal block and disperse the modified temperature of the thermal block throughout the body of the plush toy. The plush toy also has interchangeable temperature controlling garments. A heating garment is capable to heating the temperature of the body of the plush toy and a cooling garment is capable of cooling the temperature of the body of the plush toy.

Abstract: An exercise device having a hemispherical handle, an internal support, and a foot support for performing a variety of push-up type exercises. The hemispherical handle is designed to provide optimum support and comfort to the user. The internal support is attached to the handle in a way that permits the handle to move relative to the foot support, for example, by moving up and down, rotating, tilting from side to side, or revolving about a central axis. The foot support provides support for the handle. Pads may be removably attached to the foot support to provide the desired surface. A mat may be provided upon which the exercises may be performed.
