  • Patent number: 9332967
    Abstract: An assay test device comprises a cup container having a detachable top cover that has a volume-reducing internal structure. A pocket shaped and dimensioned to nest a chromatographic test strip cartridge is mounted against a flattened transparent portion of the cup side wall. The cartridge is held in a vertical position with an aperture near the top edge of the cup. A splash shield projects for the brim region of the cup over that aperture preventing any part of the sample fluid poured into the cup from entering the cartridge and contacting the test strips prematurely. When the lid is installed and the cup flipped upside-down, the internally projecting structure raises the level of sample fluid for better access to the cartridge aperture. The structure can be adapted to extend all the way through the inside of the cup to contact its closed bottom. A central cavity in the structure having a open end captures a small volume of fluid and preserves it for later confirmatory analysis.

  • Patent number: 9160553
    Abstract: This disclosure is directed to techniques for communicating in an adaptive multicast network. In general, the disclosure is directed to communicating in an adaptive multicast network. This may be done by archiving, at a rendezvous point, multicast subscription information for terminal nodes in the adaptive multicast network, wherein the multicast subscription information comprises a dynamic list of receiver terminal nodes located within the adaptive multicast network that subscribe to particular multicast streams from one or more terminal nodes in the adaptive multicast network. A router receives a multicast stream from a sender terminal node. The router receives the multicast subscription information for the multicast stream sent by the sender terminal node from the rendezvous point. The router forwards the multicast stream to all receiver terminal nodes in the dynamic list of receiver terminal nodes indicated as subscribing to the multicast stream sent by the sender terminal node.

  • Patent number: 8903962
    Abstract: A Universal Serial Bus (USB) modem/Wireless Wide Area Network (WWAN) device is provided that when connected to a host device, presents itself as an Ethernet endpoint to the host device, without requiring additional software/drivers to be downloaded to the host device. Embedded in the USB modem/WWAN device are various modules that provide functionality allowing either automatic connection to the Internet or redirection to a local Web User Interface (UI) that a user may employ to configure the USB modem/WWAN device and/or manually connect to the Internet. Additionally, the USB modem/WWAN device employs predetermined rules to determine whether or not/how the redirection occurs, including in scenarios where wireless connectivity to the Internet is unavailable.

  • Patent number: 8712473
    Abstract: A system and method for seamlessly increasing download throughput in a wireless wide area network (WWAN) device is herein disclosed. Remote file servers frequently impose per connection transfer limits upon host devices that are requesting files for download. In order to bypass these limitations, a WWAN device acting as a proxy server can replace a single file request with a series of independent requests over multiple connections, each requesting a separate portion of the original file. The blocks of requested data can then be reassembled at the WWAN device before being transferred to the device requesting the file. A user of the requesting device can therefore benefit from increased download rates, yet without having to download or install any additional software within the requesting device.

  • Patent number: 8540938
    Abstract: A spongy swab (16) is mounted against the distal face (15) of a piston (14) at the end of a push-rod (12). Once humected with a sample fluid, the swab and piston assembly is inserted into a tubular body (30) like the plunger of a syringe. As the swab is pushed and squeezed against the distal end (20) of the body up to a trippable stop, part of the fluid is excreted into a chromatographic immunoassay testing device (21) through a first aperture (19) in a distal section of the body. The remainder of the sample is kept in a sealed chamber (7) between the piston and the end wall of the tubular body until it is excreted through a second aperture (23) for a secondary test by pushing the piston beyond the trippable stop. That preserves the sample within the spongy swab that has been used to collect it; thus preventing the adsorption of the analytes on the surfaces of the sealed chamber, and to provide a convenient and rapid way to extract the remainder of the specimen in a syringe-like manner.
