Abstract: A composition and an assay solution for the determination of dissolved borate concentration comprising a catechol dye, a solubilizing agent, and a buffer are described. The composition and assay solution may further comprise a solubilizing agent. The catechol dye acts as a chemical borate sensor. The chemical borate sensor changes its optical properties upon binding to borate. The multivalent cation chelator binds multivalent cations present in a sample being analyzed. The buffer prevents changes in pH. The solubilizing agent aids in solubilizing the catechol dye, multivalent cation chelator, and/or the buffer.

Abstract: A vascular therapy device (10) includes a catheter (12) including at least one optical fiber (18) with a light output aperture (20). A containment sheath (14) has a sheath opening (13) disposed at an end thereof. The catheter is disposed inside the containment sheath and movable relative to the containment sheath to extend the light output aperture beyond the sheath opening such that the light output aperture is outside of the containment sheath. A safety sensor (22) is configured to detect whether the light output aperture is in a safe zone inside the containment sheath.

Abstract: A virtual reality system can comprise a virtual reality headset, one or more position tracking sensors, and a computerized architectural design environment. The position tracking sensors can identify a relative location of the user with respect to a physical space. The computerized architectural design environment can comprise a computer-implemented method for displaying a three-dimensional view of an architectural design to a user through the one or more virtual reality components. The method can comprise receiving a communication from the one or more position tracking sensors, rendering at least a portion of an architectural design file, and transmitting to the virtual reality headset the rendered portion of the architectural design file.

Abstract: An electrosurgical device is provided that includes a probe extending in a longitudinal direction and having a proximal region and a distal region. An inner diameter of the probe defines a lumen. The probe has an electrically insulated portion extending from the proximal region to the distal region and an electrically exposed conductive portion located at the distal region. The electrically exposed conductive portion delivers radiofrequency energy to an area of tissue adjacent the distal region. The device also includes a heat transfer system for removing thermal energy from the area of tissue that is in thermal contact with the area of tissue. The heat transfer system removes from about 0.1 Watts to about 50 Watts of energy from the tissue. In addition, the heat transfer system can sufficiently draw heat away from the tissue without the use of a peristaltic pump for circulating a liquid inside the lumen.

Abstract: A computer system for creating architectural schematics within a mixed-reality environment generates, within an architectural design application, mixed-reality rendering data that visually describes one or more virtual architectural elements in relation to a real-world environment. The computer system transmits, to a mixed-reality device, the mixed-reality rendering data, wherein the mixed-reality device renders the mixed-reality rendering data within the real-world environment. The computer system also receives a command from a user directed towards a particular virtual architectural element. Additionally, the computer system constrains a scope of the command based upon an interaction between the virtual architectural element and the real-world environment.
