Title: Virtual network solution for sms message exchange between gsm and ansi (tia/eia 41) networks
Inventor: RUPPERT PAUL R
IPC: H04W4/14
Filed: 2004-03-10
Abstract: Systems and methods for exchanging a short message service (SMS) message between networks (ANSI Carrier, ITU GSM Carrier) operating in accordance with different standards. An intermediary system (Intermediary Network) operates between a first network (ANSI Carrier) operating in accordance with a first standard and a second network (ITU GSM Carrier) operating in accordance with a second standard. A routing information request for an SMS message is received, at the intermediary, from the first network and the intermediary sends, in response to the routing information request, an acknowledgement message to the first network. The SMS message is thereafter received at the intermediary and an acknowledgement of receipt of the SMS message is generated in the intermediary and then sent to the first network. The SMS message is then sent from the intermediary to the second network. In a preferred embodiment, the intermediary is an entity distinct from the first and second networks, but operates as a virtual MSC from the perspective of the first and second networks.

Title: Propulsion mechanism for endoscopic systems
Inventor: RYDER WILLIAM T
IPC: A61B17/00
Filed: 2004-04-14
Abstract: A self propelled, endoscopic apparatus formed of a flexible, fluid-filled toroid and U motorized or powerable frame The apparatus may be used to advance a variety of accessory devices into generally tubular spaces and environments for medical and non-medical applications. The apparatus when inserted into a tubular space or environment, such as the colon of a patient undergoing a colonoscopy, is advanced by the motion of the toroid.The toroid's surface circulates around itself in a continuous motion from inside its central cavity along its central axis to the outside where its surface travels in the opposite direction until it again rotates into its central cavity. As the device advances within the varying sizes, shapes and contours of body lumens, the toroid compresses and expands to accommodate and navigate the environment.  The motion of the toroid can be powered or unpowered and the direction and speed may be controlled. The apparatus may be used to transport a variety of accessory devices to desired locations within tubular spaces and environments where medical and non-medical procedures may be performed.

IPC: C12N9/16
Filed: 2004-05-13
Abstract: This invention relates to the functional characterization of myo-inositol monophosphatase 2 (IMPA2), one of the enzymes acting in the phosphatidyl inositol signaling pathway. In particular, the present invention provides evidence that IMPA2 is associated with depression- and anxiety inducing conditions, in particular anxiety and affective disorders. In a first aspect the present invention provides the use of an IMPA2 enzyme in an assay to identify anti-anxiety or an anti-depression compounds. In particular to the use of an isolated polynucleotide encoding said IMPA2 protein, wherein said IMPA2 protein is preferably being selected from polynucleotides encoding the mouse, rat or human IMPA2 enzyme. It is thus an object of the present invention to provide a method for identifying anti-anxiety or anti-depression compounds wherein said compounds are capable of enhancing neuronal plasticity, said method comprising the steps of: a) providing a composition comprising an IMPA2 protein; b) contacting the IMPA2 protein with the test compound; and c) measuring the activity of the IMPA2 protein wherein a decrease in the IMPA2 activity in the presence of the test compound is an indicator of an anti-anxiety or anti-depression compound. In these assays the activity of the IMPA2 protein is assessed by measuring the hydrolysis of myo-inositol 1-phosphate to generate inositol and inorganic phosphate, in particular by measuring the accumulation of either myo-inositol monophosphate product in the form of radiolabeled inositol or inorganic phosphate (Pi) in the form of radiolabeled32Pi or in a colorimetric assay. The compositions comprising the IMPA2 protein could either be cellular extracts, whole cells or organisms expressing the IMPA2 proteins according to the invention.

Inventor: FULLBECK WOLFGANG F
IPC: F16L25/00
Filed: 2004-11-05
Abstract: A fitting for a sanitary hose assembly includes a rigid, tubular stem, a cylindrical ferrule, and an annular seal, which coact with the end of the hose to achieve a uniformly leakproof seal for a material flow path through the hose and into the fitting. One end of the ferrule extends over the outer end of the hose, such that the ferrule engages the hose and extends slightly beyond the hose. An inner end of the stem extends through an outer end of the ferrule and into the hose, such that the outer surface of the stem frictionally engages the internal surface of the hose. The stem has an outer end adapted to connect to a similar structure, internal threads which cooperatively engage similar threads on the ferrule, and an outwardly directed land adjacent the threads. The threaded coupling of the stem and the ferrule fixes their relative axial relationship, and also axially compresses the annular seal between. The ferrule is radially crimped to compress the end of the hose between the stem and the ferrule. This combination of components provides a circumferentially uniform and leakproof seal between the hose and the fitting, at relatively low cost.

Abstract: A method and apparatus for determining a reference time associated with a satellite positioning system. In turn, the reference time, in one embodiment, may be used to determine other navigational information. Such navigational information may include, for example, the location/position of a satellite positioning system (SPS) receiver. In one embodiment, a relative velocity between an SPS receiver and a set of one or more satellites is used to determine an offset between time as indicated by the SPS receiver and the reference time. According to another embodiment of the invention, an error statistic is used to determine the reference time. According to yet another embodiment of the invention, two records, each representing at least a portion of a satellite message, are compared to determine time. In one implementation, the SPS receiver is mobile and operates in conjunction with a basestation to determine time and/or other navigational information according to one or a combination of the methods described.
