Abstract: A computing system for wound tracking is disclosed herein. A server computing device receives a first image of a wound of a patient captured by a first camera. Subsequently, the server computing device receives a message generated by a computing device, the message indicating that a second camera of the computing device is to capture a second image of the wound. Responsive to receiving the message, the server computing device causes data to be transmitted to the computing device, the data based in part upon the first image. The data causes the computing device to present a semi-transparent overlay to a view of the wound on a display as perceived through a lens of the second camera, the semi-transparent overlay indicative of the first image. The computing device captures the second image via the second camera and causes the second image to be received by the server computing device.

Abstract: A bicycle rear derailleur has a base member mountable to a bicycle frame, a movable member movably coupled to the base member, a chain guide assembly rotatably connected to the movable member for rotation about a rotational axis, a biasing element configured and arranged to bias the chain guide assembly for rotation in a first rotational direction with respect to the movable member, and a fluid damper having a fluid cavity containing a volume of fluid. The fluid damper is operatively disposed between the chain guide assembly and the movable member to apply a damping force to the chain guide assembly when the chain guide assembly rotates in a second rotational direction opposite to the first rotational direction. The fluid damper has a guide wheel configured to route a chain and rotatable about the rotational axis.

Abstract: An electronic health records application (EHR) receives an indication that a patient in a healthcare facility has been diagnosed with an infectious disease at a datetime. The EHR determines first locations in the healthcare facility in which the patient has been present. The EHR identifies portions of a heating, ventilation, and air conditioning system (HVAC) system of the healthcare facility based upon the first locations. The portions of the HVAC system connect the first locations to second locations in the healthcare facility. The EHR identifies a person that has been present in at least one of the first locations or the second locations. The EHR then causes a notification to be transmitted to a computing device operated by the person notifying the person of potential exposure to the infectious disease.

Abstract: A bicycle rear derailleur or gear changer may include a mounting portion mountable to a bicycle frame, an electrical portion attached to the mounting portion and including power supply alignment and attachment features, and an electrical cable electrically connected to the electrical portion and electrically connectable to a printed circuit board (PCB) of a movable member movably coupleable to the mounting portion. The mounting portion and the electrical portion may be formed of different materials.

Abstract: A computing system for displaying patient data in augmented reality (AR) is disclosed herein. An AR computing device worn by a healthcare worker captures an image indicative of a patient by way of a camera comprised by the AR computing device. The AR computing device transmits the image to an electronic health records application (EHR) executing on a server computing device. The EHR retrieves patient data for the patient responsive to identifying the patient based upon the image. Responsive to receiving the patient data from the EHR, the AR computing device presents the patient data on an AR display comprised by the AR computing device. The patient data is overlaid on the AR display with a view of surroundings of the healthcare worker as perceived by the healthcare worker through the AR display.

Abstract: Technologies and techniques for biometrically authenticating a user for an apparatus. User biometric data is generated via a biometric capture device. A processor processes the user biometric data to generate one or more biometric templates. A memory stores the biometric templates and one or more previously generated biometric templates. A biometric manager module associates executable applications with respective biometric templates, wherein the processor matches one of the biometric templates with the previously generated biometric templates to determine if the matched biometric template is associated with the executable application. The processor generates at least one of a password and/or a cryptographic key for allowing access to the associated executable application based on the matched biometric template.

Abstract: Methods are provided for generating or recovering gaseous materials such as hydrogen and solids such as metals through the smoldering combustion of an organic material. The methods include admixing a porous matrix material with an organic material, and, in some embodiments a catalyst, to produce a porous mixture. The mixture is exposed to an oxidant, initiating a self-sustaining smoldering combustion of the mixture, and collecting the vapors and combustion products or processing the porous matrix following combustion to physically separate the porous matrix material from ash containing inorganic materials of value. Additional embodiments aggregate the organic material or catalyst or porous matrix material or mixture thereof in an impoundment such as a reaction vessel, lagoon or matrix pile. Further embodiments utilize at least one heater to initiate combustion and at least one air supply port to supply oxidant to initiate and maintain combustion.
