Inventor: SCHWADRON JAMES THIMOTHY
IPC: F27D99/00
Filed: 2006-03-04
Abstract: An end-piece for an additive guide tube is disclosed. Such an end piece may have a durable sleeve and a sloughable sleeve. The sloughable sleeve may have a channel through which an additive may be delivered, and the sloughable sleeve may reside in the through-hole of the durable sleeve and may be secured to the durable sleeve. When molten metal contacts the sloughable sleeve, the sloughable sleeve burns or melts and sloughs off, thereby preventing the molten metal and slag from sticking to the end-piece, which in turn prevents buildup of metal and slag.

Abstract: The Wnt signaling pathways are involved in embryo development as well as in M  tumorigenesis. Dishevelled (DvI) tra~'duces Wnt signals from the receptor Frizzled (Fz) to downstream components in canonical and non-canonical Wnt signaling pathways, and the DvI , PDZ domain plays an essential role in both pathways, and the DvI PDZ .domain binds directly to Fz receptors. In the present invention using NMR-assisted virtual ligand screening, several compounds were identified and were found to bind to the DvI PDZ domain.  Molecular dynamics simulation was used to analyze the binding between the PDZ  domain and these compounds in detail. These compounds provide a basis for rational design of high-affinity inhibitors of the PDZ domain, which can block Wnt signaling by interrupting the Fz-DvI interaction.

Abstract: The invention includes a milk cluster which includes a method and means of automatically attaching to a cows udder. The apparatus includes a milk collection chamber, milk transfer outlet, four milk cups and inflations for attachment to the teats of the cow's udder by means of a vacuum and or pneumatic operated mechanical system. Four vacuum supply ports for the purpose of employing the milking process and a main source inlet for vacuum supply. A handle grip centrally located for the purpose of maneuvering the milk cluster into positioning for automatic attachment to the cows udder. Within the handle a switch or triggering device conveniently located to maintain operation of the device with one hand.  The triggering device when activated initiates the milk cups to maneuver into the upright position for vacuum attachment. Also centrally located on the milk cluster a four point laser source directing an intense beam of light to a point where the milk cups intersect the cow's teats with the cups in the upright and attached position. Therefore as the milking process is in progress the operator needs only to maneuver the cluster in position to point the laser beam at the cows teats and activate the triggering device and the cups will move into the attach position and capture the cows teats.

Title: Website visitor coordination system and method
Inventor: MADDOX WILLIAM KEITH
IPC: H04L12/16
Filed: 2007-11-09
Abstract: A website visitor coordination method includes receiving a request for an electronic document from a user device and providing the electronic document in response. The electronic document includes executable code which searches for, and stores to, a user device visitor identification information. The code also sends data containing visitor information, such as visitor identification and a history of the webpages visited to a provider system. The provider system receives the data and, when necessary, provides a new visitor identifier to assign and transmits the new visitor identifier back to the user device. The visitor identifier is automatically incorporated in the electronic document upon the receipt, displayed on the user device, and stored for retrieval on subsequent requests for electronic documents. When a phone call is received from a website visitor, the call is associated with the visitor identifier, thus connecting the caller with the history of webpages viewed.

Abstract: Device and method for calculating distance in a communication network (100) using Time-To-Live (TTL) values Device A sets (202) a non-predictable initial TTL  value (TTL_S) and sends a message (204) with this TTL value to device B. The TLL  value should be at least as high as the TTL ceiling and lower or equal to the maximum TTL  value (normally 255). Device B reads (206) the TTL value (TTL_R) of the received message Device A and device B establish (208, 210) a Secure Authenticated Channel (SAC) (212) over which device B sends (214) the TTL value of the received message (TTL_R). Device A may then calculate (216) the distance to device B.  If TTL_R > TTL_S, this indicates an error or an attack; if TTL_R < TTL_S-TTL_C, then device B is too distant; and if TTL_S - TTL_C <= TTL_R <= TTL_S, then device A may conclude that device B a priori is within the required distance.

Abstract: A method and apparatus for predicting channel estimates for non-received signal frequencies provides knowledge of propagation channel characteristics for non-received frequencies. One embodiment predicts uplink (or downlink) channel estimates based on measured downlink (or uplink) channel estimates, which is advantageous in systems having different uplink and downlink frequencies. Another embodiment predicts channel responses for non-received OFDM sub carrier frequencies based on measuring channel responses for received OFDM sub carrier frequencies. Such processing may comprise, for example, measuring channel responses for received OFDM pilot sub carriers, predicting channel responses at frequency intervals corresponding to pilot sub carrier spacing, and interpolating between those values to predict channel responses at data sub carrier frequencies. The prediction of the channel frequency responses for non-received signal frequencies is done using an autoregression model.
