  • Patent number: 10430496
    Abstract: As may be implemented in accordance with one or more embodiments, respective sets of media content data, having disparate formats, are received from disparate content providers. The content is reformatted into a common format type and restructured into renditions having an article-oriented structure. Reformatted assets are generated for each rendition based upon characteristics of devices by which the renditions are to be accessed. Device-indeterminate ID linking data is generated for linking portions of each rendition with the media content data received from the content providers.

  • Patent number: 10422365
    Abstract: A clamp for clamping optical fiber to a tube. The clamp has a body portion coupled at one end to a first arm and at an opposing end to a second arm, and a resilient portion to permit the clamp to elastically deform from a closed state in which the clamp is fastened around the tube to an open state in which the clamp is radially moveable off the tube. At least one of the body portion, the first arm and the second arm has a clamping surface to clamp a portion of the optical fiber against the tube when the clamp is fastened around the tube, and a clamping mechanism operable to extend at least part of the clamping surface towards the tube when the clamp is secured to the tube to increase a clamping force applied by the clamping surface.

  • Patent number: 10387614
    Abstract: Systems and methods for remote control and management of medical workstations using an instant messaging infrastructure. A remote client, such as a mobile phone, laptop, tablet, or other computing device, is used to generate instructions or information requests in one or more data packets. The remote client sends the one or more data packets using the instant messaging infrastructure to a medical workstation at another location. A service application in communication with the medical workstation receives the data packets and causes the medical workstation to retrieve the requested information or execute the instruction. The communications between the remote client and the service application are encrypted and signed to ensure secure communications.

  • Publication number: 20190224440
    Abstract: A system for treating a patient suffering from obstructive sleep apnea or snoring is diclsoed. The system includes an air flow generator configured to deliver an air flow at a positive therapeutic pressure during the treatment, and an expiratory valve with an open pressure connected air flow generator. The open pressure is dependent on the therapeutic pressure from the air flow generator. The expiratory valve further exerts a back pressure upon each exhalation from the patient sufficient to create a pneumatic splint in the patient's respiratory tract. The exhalation from the patient has a first half followed by a second half and the back pressure is varied such that during the start of the first half the back pressure is between 0 and 50% of a peak back pressure and increases to a peak back pressure in the second half.

  • Patent number: 10285833
    Abstract: Stent delivery systems and associated methods for delivering stents are disclosed herein. In several embodiments, a handle assembly for delivering a stent from a tubular enclosure can include a first lead screw having a first lead thread of a first pitch and first handedness, a second lead screw having a second lead thread of a second pitch and second handedness different from the first handedness, and a housing defining threads of the first and second pitches. The first lead screw can be in mechanical communication with the tubular enclosure, and the second lead screw can be in mechanical communication with the stent. Upon rotation of a portion of the housing, the housing threads can engage the lead screws so as to induce simultaneous translations of the lead screws in opposite directions. The simultaneous translations are configured to deploy the stent from the tubular enclosure.

  • Patent number: 10177696
    Abstract: An embodiment of an apparatus for adjusting a distance between an electrode and a liquid includes a control circuit and a sense circuit. The control circuit is configured to couple an applied calibration signal to the electrode, and to cause a motor to position the electrode a distance from the liquid in response to a sense signal. And the sense circuit is configured to generate the sense signal in response to the applied calibration signal. For example, such an apparatus can be configured for use as part of a system for producing a stable solution of suspended silver. As silver-containing electrodes shorten over time, and as the level of solution changes over time, the apparatus can move the electrodes toward or away from the solution to maintain the respective distance between each electrode and the solution within a range that has been shown to produce a solution of suitable quality.

  • Patent number: 10164979
    Abstract: As may be implemented in accordance with one or more embodiments, specific electronic magazines are generated based on user interests as follows. Respective sets of media content data, associated with disparate electronic magazines provided by disparate publishers, are accessed and formatted into a common computer data format type. The formatted sets of media content data are broken into subsets and stored. Remote access to the respective subsets of media content data is provided to a user at a remote interface circuit based on authorization data specifying disparate electronic magazines that the user is authorized to access. This user access is tracked and a specific electronic magazine is generated for the user by combining disparate ones of the subsets of media content data based on both the tracked access and the user's authorization data.
