  • Patent number: 11253293
    Abstract: A fluid vessel insertion device (10), typically for medical use, comprises a puncture member (18) arranged for locaton within a sleeve (20), and a retraction mechanism (44, 48, 60) for retracting the puncture member relative to the sleeve. The puncture member (18) is retractable in use between a first condition in which an end (18A) of the puncture member protrudes beyond an end (24) of the sleeve and a second condition in which the end of the puncture member is within the sleeve (20). The retraction mechanism (44, 48, 60) actuates the puncture member between the first and second conditions in response to fluid pressure at the end (18A) of the puncture member. The device may be used during positioning of the sleeve in a desired fluid vessel, such as, for example, during intravenous cannulation.

  • Patent number: 8640159
    Abstract: Methods, systems, and devices are disclosed for reducing bandwidth consumption in a switched broadcast multimedia distribution system. When a subscriber requests a channel, bandwidth is allocated to deliver a current program to the subscriber via the requested channel. The allocated bandwidth is then terminated upon expiration of a timer. The timer may have a defined value, or the timer may correspond to program scheduling.

  • Patent number: 7600245
    Abstract: A program source is linked to event information, which is coupled via a broadcast programming communication system to a number of subscribers. Each of the subscribers to the broadcast communication system has a device for displaying programming information. The subscriber is able to perform a variety of functions to select a program of interest. Subscribers can select, view, and purchase packages or events therein. The subscriber can scroll from event wrapper to event wrapper, within the same product or between products. Furthermore, while in the product scrolling mode the subscriber may interactively purchase a multi-event PPV product by using command buttons on a remote control.

  • Patent number: 7070721
    Abstract: A hollow fiber microfiltration (MF) membrane is provided. The casting solution used to make this membrane includes a fiber-forming polymer having a degree of polymerization greater than about 1000, a water-soluble polymer, an anhydride with about 2 to 12 carbon atoms, and a solvent. The membrane is formed by mixing and heating these components to form a viscous dope and then extruding the dope through an annular orifice to form a hollow fiber MF membrane. The hollow fiber membrane is then fed through a coagulation bath and two leaching baths. The membrane is especially useful for filtering liquids, such as wine and juice, so as to remove bacteria, gel, and solid particles from the liquids.

  • Publication number: 20050289638
    Abstract: Methods, systems, and products are disclosed for providing video and IP data over a common, shared coaxial interface. One method receives radio frequency signals via an input of a device. The input includes an interface to a coaxial cable. Packets of data are also received via the same input. Demodulation then recovers the packets of data and/or the radio frequency signals.

  • Publication number: 20020047894
    Abstract: The system according to this invention comprises a program source linked to event information, which is coupled via a broadcast programming communication system to a number of subscribers. Each of the subscribers to the broadcast communication system has a device for displaying programming and either coupled to the display device or built into the display device is one component thereof, a set top box by which the subscriber is able to perform a variety of functions to select and cause to be displayed a program of interest. Subscribers can select, view information able particular packages or events therein and purchase desired packages or events therein. The invention accomplishes these features by packaging associated PPV events into products that are contained within a single product wrapper. To view individual events, the system allows a subscriber to remotely cause the EPG system to enter a second viewing mode.
