Abstract: A ride system includes a track and an overhung ride assembly. The overhung ride assembly includes a transport platform coupled to the track, a ride vehicle, and a heave system extending between the transport platform and the ride vehicle. The heave system is configured to heave the ride vehicle relative to the transport platform. The heave system includes an extendible tube defining a variable volume configured to store a gaseous fluid. The extendible tube is configured to extend in response to a lowering of the ride vehicle away from the transport platform by the heave system such that the gaseous fluid within the variable volume of the extendible tube provides a fluid force that biases the extendible tube toward a contracted configuration to assist the heave system with a lifting of the ride vehicle toward the transport platform.

Abstract: A high pressure osmotic dispense pump (10) having a substantially continuous delivery rate and extended delivery times is described and disclosed. The dispense pump (10) includes a semi-permeable membrane (12) which is substantially free of distortions and lateral stretching stresses. The membrane housing (14) and configuration of the present invention allows for consistent and accurate flow rates at the micro-liter level and improved control of the surface area of the semi-permeable membrane (12). This osmotic pump (10) also includes optional methods for activating and deactivating the osmotic process and/or controlling flow rates. Along with these features, the pump can be amplified or modulated to increase the dispense rate and/or adjust the flow rate during operation.
