  • Patent number: 11935139
    Abstract: A computer system that is adapted for: (A) displaying a geographical map on a display screen; (B) displaying a plurality of icons on the geographical map, each of which generally represents the current location of at least one individual; (C) allowing a user to select a group of the icons; and (D) after the user selects the group of icons, providing messaging functionality for allowing the user to send a common message to the respective portable computing devices of at least substantially all of the individuals who correspond to the selected group of icons. In particular embodiments, the system allows the user to send the message by executing a single activity, such as selecting a single button. The system may also be configured to approximate the current location of an individual based on the individual's current travel itinerary.

  • Patent number: 11406352
    Abstract: Systems can include at least one friction wheel configured to engage a catheter of an intravascular system such that proximal or distal motion of the catheter causes the friction wheel to rotate. A position sensor can include a reference element and a movable element, wherein the movable element is configured to move relative to the reference element in response to rotation of the at least one friction wheel. The position sensor can provide a position signal representative of the rotation of the at least one friction wheel. An intravascular processing engine can receive both the position signal from the position sensor and an intravascular signal from the catheter.

  • Publication number: 20150119709
    Abstract: A powered medical fluid injector may have a disposable medical fluid injection manifold that controls fluid routing between the injector and a patient line and also controls fluid flow to a pressure sensor contained within the manifold. In one example, the medical fluid injection manifold includes a manifold housing having at least two inlets for different pressurized medical fluids and at least two corresponding outlets. The medical fluid injection manifold may also have a pressure sensor configured to measure a hemodynamic pressure of a patient. The pressure sensor may be positioned within the manifold housing and in selective fluid communication with the one of the outlet ports of the manifold housing.

  • Publication number: 20110075871
    Abstract: A hearing aid has a suspension portion received in the wearer's concha bowl and an electronics portion. The suspension portion is formed of a flexible rubbery material, while the electronics portion includes a shell formed of a rigid plastic material. The suspension portion is provided as a ring having an annulus, and bears off a tragus contact area, an antitragus contact area and an antihelix contact area to support the receiver in a suspended, cantilevered position within the ear canal. The microphone can be within the flexible ring housing portion. The hearing aid makes much more comfortable contact with the concha bowl.
