Abstract: A computer-implemented layout tool includes a mechanical design engine for configuring mechanical design components to be included in a design, an electrical design engine for configuring electrical components to be included in the design, a constraint engine for identifying a 3D printer to be used to print the design and to provide design constraints including feedback for inoperative or impermissible configurations of one or more mechanical components or electrical pathways associated with the design; and a simulation engine for simulating, at least, electrical performance of the design based on one or more electrical components added to the design after printing and proposed electrical pathways.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a storage medium, for integrating components into objects that are to be 3D printed. One of the methods includes obtaining a three-dimensional model of a first object; receiving an input identifying an additional component; generating a digital representation of the additional component; integrating the digital representation of the additional component with the three-dimensional model; and providing the three-dimensional model with the integrated digital representation to a 3D printer for fabrication.

Abstract: A reservoir for storing and dispensing a fluid, the reservoir comprising a hollow vessel for holding a volume of fluid, an inlet port located on the hollow vessel for filling the reservoir with fluid, an outlet port located on the hollow vessel for dispensing the fluid, and a vent outlet located on the hollow vessel to permit venting during filling and dispensing operations. The vent outlet is provided in the form of a vent tube having a vent seal located at a base thereof. The vent seal allows for venting as required, while also serving as a flow restrictor to reduce the leakage of fluid from the vent tube in the event of sloshing within the reservoir.

Abstract: The invention relates to a method for preparing or effecting access, in data transmission, from a first application which is run on a client data processing device to a transmission medium which is coupled to the client data processing device. The steps performed are: providing a second application which includes at least one interface for converting the format of information, transmitted by the first application, to a standard format which is predetermined by the second application; and registering the second application with the client data processing device or installing the second application on the client data processing device in order to transmit the information of the first application in the standard format between the second application and the transmission medium or to enable the information of the first application to be transmitted in the standard format between the second application and the transmission medium.

Abstract: Vacuum pump of reciprocating piston and cylinder type. Cylinder is stepped to have front large diameter portion and rear small diameter portion. Piston has enlarged head portion sliding in front portion of cylinder and rear portion sliding in rear portion of cylinder. Front end of cylinder is closed to form high vacuum pumping chamber swept by front face of piston head. Gas enters the high vacuum pumping chamber through side wall of cylinder and can be exhausted through exhaust valve in closed front end of cylinder. Rear annular face of piston head sweeps lower vacuum chamber in cylinder behind the piston head. A gas transfer passage extends through cylinder wall from front end of high vacuum pumping chamber to port in cylinder wall so as to transfer gas from high vacuum chamber to lower vacuum chamber when piston approaches end of forward stroke. Gas is transferred through transfer duct at pressures lower than required to open the exhaust valve.
