Die Abfüllung von Flüssigkeiten mit pneumatisch betätigten Ventilen

Filling of Liquids with Pneumatically Operated Valves The application and working principle of some valve constructions are described. Using the appropriate valves for the different purposes in combination with automatic balances and transport systems, optimum operational conditions are achieved. Maximum capacities are attained in continuous operation using pneumatically driven valves. The weighing losses in automatic filling are minimized due to elimination of sources of human error and the wages and salaries are reduced considerably.     

Challenges and opportunities for next-generation intracortically based neural prostheses

Neural prosthetic systems aim to help disabled patients by translating neural signals from the brain into control signals for guiding computer cursors, prosthetic arms, and other assistive devices. Intracortical electrode arrays measure action potentials and local field potentials from individual neurons, or small populations of neurons, in the motor cortices and can provide considerable information for controlling prostheses. Despite several compelling proof-of-concept laboratory animal experiments and an initial human clinical trial, at least three key challenges remain which, if left unaddressed, may hamper the translation of these systems into widespread clinical use. We review these challenges: achieving able-bodied levels of performance across tasks and across environments, achieving robustness across multiple decades, and restoring able-bodied quality proprioception and somatosensation. We also describe some emerging opportunities for meeting these challenges. If these challenges can be largely or fully met, intracortically based neural prostheses may achieve true clinical viability and help increasing numbers of disabled patients.
