  • Patent number: 10596757
    Abstract: Augmented three-dimensional (3D) printing systems and methods for constructing and mineralizing a hydrogel structure with defined geometry are disclosed. One example embodiment is a system for three-dimensional printing and mineralizing a polymer. The system includes a three-dimensional printer unit with a syringe extruder, a fluid delivery system operatively coupled to the three-dimensional printer unit, and a control unit. The control unit is operatively coupled to the three-dimensional printer unit and fluid delivery system, and is configured to (i) cause the three-dimensional printer unit to print a portion of a three-dimensional polymer object, (ii) cause the fluid delivery system to flush the portion of the three-dimensional polymer object with a fluid to mineralize the portion of the three-dimensional polymer object, and (iii) cause the three-dimensional printer unit to print a subsequent portion of the three-dimensional polymer object.

  • Patent number: 10288881
    Abstract: A wearable interface device, such as a head-mounted display, provides an augmented reality and/or display system and may be used in accordance with medical devices and the performance of medical treatments, particularly a dialysis machine and a dialysis treatment. The wearable interface device may be worn by a user, such as a health care practitioner (HCP), in connection with remotely monitoring and/or controlling the dialysis machine during the dialysis treatment. The HCP may receive alerts and/or other information concerning the dialysis treatment from the dialysis machine that are displayed on the wearable interface device and may use the wearable interface device to control the dialysis machine via the exchange of wireless signals with the dialysis machine. The wearable interface device may recognize commands from the HCP, such as gestures, to provide non-contact operation of the wearable interface device and remote control of the dialysis machine by the HCP.

  • Patent number: 7973667
    Abstract: The present invention relates to a wetness detector system that rapidly detects the presence of wetness due to a liquid leak in a system. The wetness detector system contains a reusable wetness sensor that is able to accurately detect the presence of wetness and, in the case of an extracorporeal blood treatment, the presence of blood. The wetness detector system can quickly alert both a user and medical personnel that a liquid leak has been detected in a treatment system and, if necessary, halt the removal of liquids and/or blood from the patient. If a liquid leak is not detected for a period of time, the wetness sensor can enter a low power state, extending the life of the device. The wetness detector system can monitor a number of wetness sensors simultaneously, which would, for example, eliminate the need for medical personnel to continuously inspect numerous patients visually for potentially fatal blood leaks due to needle dislodgement during an extracorporeal blood treatment.

  • Publication number: 20060026522
    Abstract: A method, computer readable medium and system are provided which implement a change in a specialized model. In the method, a change made by a user to an instance of the specialized model is detected. A potential revision, to at least one of a master model and a map used to generate the specialized model, is identified based upon the detected change. The potential revision is suggested to the user, and is automatically made if the user instructs.

  • Patent number: 3962815
    Abstract: A box-like container for storing spools of fishing line, in which replacement fishing line is readily unwound in a selected length through a cooperating dispensing opening in the container wall. Unwinding rotation of the spool is achieved by journalling the spool on an axle mounted centrally across the storage compartment of the container. One end support for the axle is a closure member which is force fit over a side access opening into the storage compartment, said force fit being established with a portion of the container wall extending beyond the end member and, as such, functioning as a gripping lip.
