Abstract: A fluidic device controls fluid flow in channel from a source to a drain. In some embodiments, the fluidic device comprises a channel and a gate. The channel is configured to transport a fluid from the source to the drain. The gate controls a rate of fluid flow in the channel in accordance with the fluid pressure within the gate. Specifically, the gate is configured to induce a first flow rate of the fluid in the channel in accordance with a low pressure state of the gate, and a second flow rate of the fluid in the channel in accordance with a high pressure state of the gate. In certain embodiments, the first flow rate is greater than the second flow rate. In alternative embodiments, the second flow rate is greater than the first flow rate.

Abstract: A fluidic device comprises a channel, a gate, and one or more additional elements. The channel is configured to transport a fluid from a source to a drain. The gate includes a chamber with an adjustable volume that affects fluid flow within the channel by displacing a wall of the channel toward an opposite wall of the channel based in part on fluid pressure within the chamber exceeding a threshold pressure. A high pressure state of the gate corresponds to a first chamber size and a first flow rate of the fluid. A low pressure state of the gate corresponds to a second chamber size that is smaller than the first chamber size and a second flow rate that is greater than the first flow rate. The additional elements are configured to reduce the threshold pressure past which the chamber decreases the cross-sectional area of the channel.

Abstract: Embodiments relate to a system and a method for providing haptic feedback to a user by controlling an area of a surface of a haptic assembly in touch (directly or indirectly) with a user. The haptic assembly can be actuated such that a surface area of the haptic assembly in contact with a user can be adjusted. An area of the haptic assembly in contact with a user can be changed by modifying a shape of the haptic assembly. Hence, by changing the shape of the haptic assembly, a user touching a virtual object in a virtual space with a particular rigidity can be emulated.
