Abstract: An engineering optimization method based on an Exact Polynomial Algorithm for solving of the 0/1 Knapsack Problem is described. This method has a wide variety of industrial and scientific applications including engineering design, naval, aerospace, internet security, and computer science, amongst others. The method searches the vast solution space for the focused set of Pareto optimal alternatives. At each level of optimization it employs a forecasting procedure to eliminate the non-productive combinations of items with the weight sum exceeding the knapsack capacity, a Pareto optimization procedure to eliminate non-optimal solutions, and a duplicate elimination procedure to exclude all but one of the combinations of items with the identical weights and values. This optimization approach tremendously reduces the scope of the problem and provides an industrial engineer with an efficient tool to generate and compare different design solutions under some measurable restrictions.

Abstract: A mobile station is configured to respond to a mobile messaging service message bearing a predetermined code to determine its location and send location information back to the requestor in a response message. Typically, the mobile station received such a message from another mobile station. However, the mobile station does not display the received message or generate any alert regarding the received message, which might otherwise inform someone with or near that mobile station of the location related messaging.  For example, if a mobile station is lost or stolen, the user can borrow another person's mobile device and send out a message with the code to the missing mobile station phone, to obtain information as to the location of the user's missing mobile station.

Title: Suction teat unit
Inventor: PFENNIGER ERICH
IPC: A61J11/00
Filed: 2009-06-09
Abstract: The teat unit for sucking a liquid from a liquid container comprises a teat (4) and a flow restrictor with a through-opening (32). The teat (4) comprises a mouthpiece (42), with a suction opening (43), and a main body (40) which is formed integrally on the mouthpiece (42) and widens relative to the mouthpiece (42). The flow restrictor defines a maximum flow of the liquid passing through the suction opening (43) from the liquid container. According to the invention, the flow restrictor is arranged outside the mouthpiece (42), and the suction opening (43) has a greater cross--sectional surface area than the through-opening (32) of the flow restrictor. The teat unit permits a feeding action that is as true to nature as possible, since the mouthpiece (42) can be deformed very considerably, without substantially impairing the flow restriction.

Title: Wave actuated pump and means of connecting same to the seabed
Inventor: TILLOTSON ROBERT
IPC: F03B13/18
Filed: 2009-07-10
Abstract: A pumping apparatus designed for the purpose of economically harvesting the energy of the waves on the surface of a body of water and converting such energy into hydraulic power which may be transmitted by pipes and used for any purpose but preferably for the generation of electricity or the production of desalinated water. To better explain the means of operation of this invention, referring to Figurei, I will start by assuming that the float (14) is static, the accumulator (30) is pressurized above the ambient pressure of the environment of pump, the accumulator(30) is charged with fluid and the pump is full of fluid. In this condition check valve (10) is closed and pumping chamber (19) is pressurized by the accumulator (30). Pumping chamber (18) is also equally pressurized via the piston (2). An axial force is generated on rod or tube (3) by the pressure difference between its ends. A similar, but opposite, axial force is generated on rod or tube (4) by the pressure difference between its ends. Rod or tube, (4) is larger in diameter than rod or tube (3) and hence the magnitude of the force on rod or tube (4) is greater. The resultant of these forces is a net downward force on the operably connected float (14).  This force will be balanced by a portion of the buoyancy of float (14).     to keep the system in equilibrium. By this means the whole pump string, from float to foundation, is maintained in tension. If now we assume that a rising wave acts upon the float (14) an upward force will be generated by both the kinetic energy of the rising water and by the increasing buoyancy of the float. This force will overcome the above mentioned downward force and the float (14) along with the operably connected piston (2) will move relative to the cylinder (1) causing volume reduction of pumping chamber (19), closing of check valve (9) and hence displacement of fluid into the discharge line (5). Simultaneously, pumping chamber (18) will increase in volume causing fluid to enter it via check valve (10) and port (11). When the float has reached the top of the wave and the wave then begins to descend check valve (9) opens, check valve (10) closes, and the above mentioned force due to the difference in diameter of rods or tubes (3 and 4) will cause the piston (2) to move, relative to the cylinder (1), in an opposite direction to the first stroke therefore causing pumping chamber (19) to expand and pumping chamber (18) to contract.  Fluid will therefore pass through the hollow piston via port (11), check valve (9) and port (12) from pumping chamber (18) to pumping chamber (19). The pump is thus reset and ready for the next pumping stroke caused by the next rising wave.

Abstract: An example of a vertically operating door includes a flexible panel comprising two pliable sheets of material with a plurality of pads or mats of thermal insulation between the two sheets. In some examples, a plurality of horizontally elongate baffles made of pliable strips of material are installed between the two sheets. The baffles effectively divide one large interior volume between the sheets into more manageable smaller volumes or chambers. The baffles restrict the air between the sheets from being forced to the bottom of the panel as the panel ascends and bends across an overhead roller. Without the baffles and smaller chambers, the panel sheets in the area near the bottom of the panel would tend to bulge outward as the door opens.
