A fluid end for a high-pressure pump including a unitary body with a plurality of horizontal passages each for receiving a reciprocating plunger at one of its ends and a pressure relief valve at the other of its ends. The body is provided with a corresponding number of vertical passages each of which intersect one of the horizontal passages and contains a suction valve at its bottom and a discharge valve at its top. A suction manifold is hingedly attached to the bottom of body to provide a flow of fluid into the body via the suction valves. A discharge passage intersects the vertical passages and receives fluid pressurized by the plungers via discharge valves and ports such from the fluid end.

An organ perfusion apparatus and method monitor, sustain and / or restore viability of organs and preserve organs for storage and / or transport. Other apparatus include an organ transporter, an organ cassette and an organ diagnostic device. The method includes perfusing the organ at hypothermic and / or normothermic temperatures, preferably after hypothermic organ flushing for organ transport and / or storage. The method can be practiced with prior or subsequent static or perfusion hypothermic exposure of the organ. Organ viability is restored by restoring high energy nucleotide (e.g., ATP) levels by perfusing the organ with a medical fluid, such as an oxygenated cross-linked hemoglobin-based bicarbonate medical fluid, at normothermic temperatures. In perfusion, organ perfusion pressure is preferably controlled in response to a sensor disposed in an end of tubing placed in the organ, by a pneumatically pressurized medical fluid reservoir, providing perfusion pressure fine tuning, overpressurization prevention and emergency flow cut-off. In the hypothermic mode, the organ is perfused with a medical fluid, preferably a simple crystalloid solution containing antioxidants, intermittently or in slow continuous flow. The medical fluid may be fed into the organ from an intermediary tank having a low pressure head to avoid organ overpressurization. Preventing overpressurization prevents or reduces damage to vascular endothelial lining and to organ tissue in general. Viability of the organ may be automatically monitored, preferably by monitoring characteristics of the medical fluid perfusate. The perfusion process can be automatically controlled using a control program.

The present invention relates to a wheelchair with forced driven front caterpillar wheels with a cable-hauling ratchet lever by which a user, by himself / herself, can pass over a road-block or drains on roads, lifts up the caterpillars from the ground for easy steering on caster wheel, engages / disengages the drive wheel having ratchet clutch in the detachable wheel hub to idle the drive wheel / caterpillars for converting from / to manual drive to / from drive by auxiliary power source, and prevents the drive wheel from rolling backward during climbing inclines and controls speed continuously on a slope by a band brake means. So the disabled persons on their legs can travel to outdoors by himself / herself without a care of neighbors.

Systems and methods for securing or encrypting data or other information arising from a user's interaction with software and / or hardware, resulting in transformation of original data into ciphertext. Generally, the ciphertext is generated using context-based keys that depend on the environment in which the original data originated and / or was accessed. The ciphertext can be stored in a user's storage device or in an enterprise database (e.g., at-rest encryption) or shared with other users (e.g., cryptographic communication). The system generally allows for secure federation across organizations, including mechanisms to ensure that the system itself and any other actor with pervasive access to the network cannot compromise the confidentially of the protected data.

A method for controlling a pump for delivery of liquid to an organ over a series of fixed-length time intervals f, each interval f comprising a time t1 and a time t2 wherein t1+t2 equals the length of interval f. The method comprises allowing output pressure of the pump to decrease over time t1, increasing output pressure of the pump over time t2, comparing achieved pump output pressure to a predetermined pressure at about the end of interval f, and at least one of (i) adjusting t1 and t2 if necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval f, and (ii) adjusting a rate of change of the output pressure during at least one of t1 and t2 if necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval f.

The invention is targeted at the process of separating gas, such as air, from a liquid path. Specifically, the invention provides a means to remove gas from a dynamic liquid path, manage the removed gas and liquid path. The invention provides a means to remove gas from a dynamic liquid path using the buoyant property of gas in a less buoyant liquid, having ingress and egress ports for liquid and gas flow, and separate points of egress for liquid and trapped gas and integral liquid channels.

A method for connection roaming a Mobile Node (MN) to a Network GateWay (NGW) for providing secure data path using Internet Protocol (IP) security procedure. Also Mobile IP (MIP) is required for providing mobility to the user, when the MN moves from one sub-network to another. However, when the Home Address of the network is not known, a cyclic interdependency is observed between the IP Security (Ipsec) procedures and IP procedures. If the home address of the MN is not known initially during the procedure, IPsec Security Associations (SA's) are formed between the MN and NGW such that only IP packets are passed through. After the IP Registration is completed, the Home Address of the MN is known from the MIP registration Reply. MN now forms a data path tunnel with the NGW by exchanging Create_Child_SA messages.

During the period in which the organ is preserved and / or maintained, various drug research and development may be performed on and / or with the organ. The organ may be perfused with a fluid containing a substance such as a test substance to obtain data regarding the organ, the substance and an interaction of the substance and the organ. The data may then be used to ultimately provide information regarding the drugs efficacy in support of regulatory filings for new drugs.

A control apparatus is used in a vehicle that performs automatic travel control. The apparatus includes a search section which searches for an external unit, when information used for the automatic travel control is no longer available due to abnormality, the external unit providing assist information for complementing missing information that is the information no longer available due to the abnormality, an acquisition section which acquires the assist information from the external unit obtained as a result of the search of the search section, and a processing section which performs a process for performing assist travel control, which is the automatic travel control as a result of complementing the missing information with the assist information.

A portable storage unit to carry, store and organize, various sports sticks, garden tools and other household items that require upright storage either on a permanent or temporary basis consisting of a pair of rigid side members that in the open position are spaced apart and a support section provided between the two side members, the support section adapted to permit the side members to move from an open spaced apart position to a closed adjacent position to permit the portable storage unit to be carried in one hand.

A rotating barbell support rotatably holds a barbell in at least a first position and a second position by rotating the barbell between such positions. A user may lie on a bench and rotate the barbell to his or her lifting sweet spot while the rotating barbell support continues to support the weight of the barbell. The user may then begin one or more bench presses from his or her sweet spot without the need to maneuver the full weight of the barbell or the need for a spotter. The rotating barbell support may have a pair of biased support assemblies, each having a support arm and a post. The support arm may have a weight, spring, or elastic element attached thereto, while the post may have a barbell holder. The posts of the support assemblies may be biased to a backward tilted angle by the weight.
