  • Patent number: 11952592
    Abstract: Organs-on-chips are microfluidic devices for culturing living cells in micrometer sized chambers in order to model physiological functions of tissues and organs. Engineered patterning and continuous fluid flow in these devices has allowed culturing of intestinal cells bearing physiologically relevant features and sustained exposure to bacteria while maintaining cellular viability, thereby allowing study of inflammatory bowl diseases. However, existing intestinal cells do not possess all physiologically relevant subtypes, do not possess the repertoire of genetic variations, or allow for study of other important cellular actors such as immune cells. Use of iPSC-derived epithelium, including IBD patient-specific cells, allows for superior disease modeling by capturing the multi-faceted nature of the disease.

  • Patent number: 9391878
    Abstract: In one embodiment, a device in a computer network establishes a reliable map that defines a set of packet criteria for which reliability is desired over an unreliable link to a peer device. In response to receiving a first packet from the peer device over the unreliable link, the device acknowledges the first packet to the peer device when the first packet matches the packet criteria of the reliable map. Also, in response to receiving a second packet destined via the peer device over the unreliable link, the device buffers the second packet when the second packet matches the packet criteria of the reliable map and retransmits the buffered second packet over the unreliable link to the peer device until acknowledged by the peer device.

  • Patent number: 9294584
    Abstract: In one embodiment, a router establishes a serial-over-TCP/IP (Transmission Control Protocol/Internet Protocol) communication session between terminal units using raw-TCP encapsulation. For the session, the router maps serial characters to TCP out-of-band (OOB) communication fields, maps serial flow control signals to TCP/IP receiver-window advertisements, and dynamically adjusts a TCP/IP priority based on serial payload priority. Accordingly, the router may thus communicate data over the serial-over-TCP/IP session based on the mappings and priority.

  • Patent number: 8949959
    Abstract: In one embodiment, a management device in a computer network determines when nodes of the computer network join any one of a plurality of field area routers (FARs), which requires a shared-media mesh security key for that joined FAR. The management device also maintains a database that indicates to which FAR each node in the computer network is currently joined, and to which FARs, if any, each node had previously joined, where the nodes are configured to maintain the mesh security key for one or more previously joined FARs in order to return to those previously joined FARs with the maintained mesh security key. Accordingly, in response to an updated mesh security key for a particular FAR of the plurality of FARs, the management node initiates distribution of the updated mesh security key to nodes having previously joined that particular FAR that are not currently joined to that particular FAR.

  • Patent number: 8274353
    Abstract: An inductor circuit is disclosed. The inductor circuit includes a first in-silicon inductor and a second in-silicon inductor each having multiple turns. A portion of the multiple turns of the second in-silicon inductor is formed between turns of the first in-silicon inductor. The first and second in-silicon inductors are configured such that a differential current flowing through the first in-silicon inductor and the second in-silicon inductor flows in a same direction in corresponding turns of inductors.

  • Patent number: 7899409
    Abstract: A transceiver is described that includes a power amplifier (PA), a low noise amplifier (LNA), and an impedance matching circuit having a first and second differential output node. The first and second differential output nodes are coupled to outputs of the PA and to inputs of the LNA. The impedance matching circuit provides a load impedance to the outputs of the PA. The transceiver further includes a first impedance device having an output impedance coupled between the first and second differential output nodes. In this way, the combination of the output impedance and the load impedance matches with an impedance at the inputs of the LNA.

  • Publication number: 20050029741
    Abstract: A casino table poker game comprises a player makes an Ante wager to play in the poker game, and a first number of cards being dealt to the player. A second number of cards is dealt to a dealer. The second number of cards dealt to the dealer is greater then the first number of cards dealt to players. The dealer displays at least a first card from the second number of cards dealt to the dealer. The at least first card analyzed by an automatic game rule of play to determine whether the card must be discarded. If the rule operates to require the at least first card be discarded according to the automatic game rule, the dealer must play the dealer hand with fewer then the second number of cards dealt to the dealer. After a final number of cards has been decided in the dealer's hand, the poker game is played to conclusion according to the game rules.
