Abstract: An iontophoresis device (10) includes a membrane applied to said skin having a drug delivery aperture, a solvent delivery aperture and a vent aperture for applying a vacuum between the membrane and skin. A drug cartridge defines a drug containing chamber in communication with the drug delivery aperture and a drug air chamber separated by a first flexible membrane. A solvent cartridge defines a solvent containing chamber and a solvent air chamber separated by a second flexible membrane. An electrode is positioned between the membrane and the skin and surrounds the drug delivery aperture and the solvent delivery aperture. A drug cartridge may also include two separate chambers, one containing a lyophilized agent, the other containing a solvent. The solvent and the agent remain separate until mixed during operation of the device.

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: A rear derailleur includes a base member mountable to a bicycle frame, a movable member movably coupled to the base member, and a pivot member rotatably coupled to the movable member. The rear derailleur also includes a chain guide assembly rotatably connected to the movable member via the pivot member. The rear derailleur includes a damper device disposed within the movable member. The damper device is operable to apply a damping force to the chain guide assembly when the chain guide assembly rotates. The damper device includes a friction member having a friction surface. A first portion of the friction surface is in frictional engagement with the pivot member, and a second portion of the friction surface is in frictional engagement with the movable member. The friction device is disposed within the movable member at a distance relative to the biasing device in an axial direction along the pivot member.

Abstract: A polarization-separated, phase-shifted interferometer can generate interferograms without moving parts. It uses a phase shifter, such as an electro-optic phase modulator, to modulate the relative phase between sample and reference beams. These beams are transformed into orthogonal polarization states (e.g., horizontally and vertically polarized states) and coupled via a common path (e.g., polarization-maintaining fiber) to a polarizing beam splitter (PBS), which sends them into separate sample and reference arms. Quarter-wave plates in the sample and reference arms rotate the polarization states of the sample and reference beams so they are coupled out of the PBS to a detector via a 45° linear polarizer. The polarizer projects the aligned polarization components of the sample and reference beams onto the detector, where they interfere with known relative phase to produce an output that can be used to map surface topography of the test object.

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: Electronic messages, such as emails, often ask questions, ask that a task be done, or assign a task. The responsive messages often forget to answer the questions and the responders often forget to calendar tasks. Advances in natural language processing provide computers the ability to notice the questions and task requests/assignments. Automated analysis of the messages can detect and highlight questions, can provide for draft responses addressing every question, and can provide for getting tasks calendared.

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.
