Abstract: Systems and methods are provided for testing the load state of at least one device or communication network in the loaded state. The system includes at least one programmable control device and at least one session computer connected to, or integrated with, the control device. The control device stores a plurality of session scripts which may be pre-compiled and individually interactive. The session scripts may contain an initialization procedure, a predefined test procedure, and a termination procedure. The session computer includes: a plurality of mutually independent logical or physical connection interfaces; and a plurality of script-processing devices being able to simultaneously establish mutually independent connections to a device to be tested. Each script-processing device executes at least one session script received from the control device through each of the mutually independent connection interfaces to simulate a load of a plurality of users on the device to be tested.

Abstract: A method is provided for automatically sorting and packing batches of products, such as, for instance, eggs or fruits which are each provided with an origin code. The method includes supplying first batches of coded products to a sorting apparatus and simultaneously assigning the corresponding codes to fields of a register of a computer program. The products are subjected to criteria in at least one classification apparatus and the products are marked with classification data as obtained with the classification apparatus, while for each individual product the codes and the data are assembled with the computer program in fields of the register to form a label. The classified products are sorted and subsequently packaged to form second, sorted batches of products at packing stations of a packing apparatus.

Abstract: A system and a method for testing at least one device in a communications network based on an IP-standard (internet protocol standard), in the loaded state and/or for a plurality of users. The system and method may test the load state of the IP-based networks in a semi-automated fashion. Such a system and method may include at least one programmable control device having an assigned memory device, in which a plurality of session scripts is able to be stored, which each contain a predefined test procedure, and at least one session computer connected to the control device and has a plurality of mutually independent connection interfaces for executing at least one session script. Via each connection interface, an independent IP connection to the communications network may be established.

Abstract: A flexible system for changing the physical manifestation of an object in an object-oriented computer environment. An object to be manifested, denominated a "costume" object, is associated with a target object having a corresponding physical appearance. The costume object accepts a physical manifestation request and responds by transmitting to the target object a message requesting that the target object manifest itself. The target manifestation request message includes parameter values specifying the on-screen location and other properties of the costume object. In this fashion, the costume object can present itself wearing the appearance or "costume" of the target object.

Abstract: A flexible system for changing the physical manifestation of an object in an object-oriented computer environment is provided. The object to be manifested (a "costume" object) is associated with a target object having a corresponding physical appearance. The costume object responds to requests that it physically manifest itself by transmitting a message to the target object requesting that the target object manifest itself, but also including parameter values describing the costume objects on-screen location or similar properties. In this manner, a costume object is capable of presenting itself wearing the target object's "costume" or appearance.

Abstract: A gas injector for a gas fueled internal combustion engine having a valve member that is movable between a first or closed position, in which a flow of gas through the injector is prevented, and a second or open position in which a flow of gas is permitted through the injector. A solenoid actuator moves the valve member from the first to the second position responsive to an electrical control signal which is modulated to precisely control the quantity of gas to be delivered by the gas injector to the internal combustion engine. The valve member includes a hollow valve stem having a first opening at one end and a second opening in the form of three radial apertures at the other end to allow a flow of gas through the valve member in use. The valve stem is provided with an annular flange of magnetic material at one end, which faces the end face of the solenoid actuator and forms the armature of the magnetic circuit formed by the solenoid actuator.
