Publication number: 20200064917Abstract: A fluidic-device valve having a valve guide with a guide wall surrounding a central axis. The guide wall may include a first guide section, a second guide section, and an interior surface that defines a valve cavity extending longitudinally along the central axis. The valve may also include a valve member disposed within the valve cavity, and the valve member may extend longitudinally along the central axis between a first end and a second end of the valve member. The valve member may be movable within the valve cavity in a first axial direction along the central axis to position a fluid conduit defined by the valve member at a first location by increasing a pressure applied to the second end of the valve member by a pressure source coupled to the second guide section. Various other apparatuses, systems, and methods are also disclosed.Type: ApplicationFiled: August 27, 2018Publication date: February 27, 2020Inventors: Riccardo DeSalvo, Xavier Clark Talbot-Thiebaux, Jack Lindsay

Patent number: 10514111Abstract: 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.Type: GrantFiled: November 28, 2017Date of Patent: December 24, 2019Assignee: Facebook Technologies, LLCInventors: Sean Jason Keller, David R.

Patent number: 10502327Abstract: 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.Type: GrantFiled: September 15, 2017Date of Patent: December 10, 2019Assignee: Facebook Technologies, LLCInventors: Sean Jason Keller, David R. Perek, Tristan Thomas Trutna, Garett Andrew Ochs, Nicholas Roy Corson, Raymond King, Jack Lindsay, Riccardo DeSalvo, Joseph Minh Tien, Matthew Robert Schwab

Patent number: 10481262Abstract: An optical sensor measures displacement of a haptic plate that provides haptic sensation to a user. The optical sensor comprises a light source, a plurality of optical detectors, and a controller. The light source is configured to illuminate a surface of the haptic plate in which a haptic wave propagates causing displacement of portions of the haptic plate in one or more directions. The plurality of optical detectors is configured to detect light reflected from the surface of the haptic plate. At least two optical detectors of the plurality of optical detectors are positioned relative to the light source such that an amount of light received at each of the optical detectors is based at least in part on a direction of displacement of the haptic plate. The controller is configured to monitor the haptic wave using the detected light from the plurality of optical detectors.Type: GrantFiled: October 19, 2017Date of Patent: November 19, 2019Assignee: Facebook Technologies, LLCInventors: Riccardo DeSalvo, Ian Andreas Marquez, Jeff Jakkit Ongnok

Patent number: 10451707Abstract: A system includes a locatable glove and a pose determination device. The locatable glove includes a glove body worn over a hand of a user, and a plurality of positioning transponders. The positioning transponders are coupled to the glove body at various positions on the glove body, and each re-radiates a received signal, the re-radiated signal unique to the positioning transponder. The pose determination device includes a plurality of antennas and a controller. The antennas are each configured to receive the unique signals re-radiated by the positioning transponders. The antennas are physically separated from each other. The controller is communicatively coupled to the plurality of antennas, and is configured to determine, for each of the received unique signals, a location of the position on the locatable glove of the positioning transponder corresponding to the unique signal.Type: GrantFiled: January 18, 2018Date of Patent: October 22, 2019Assignee: Facebook Technologies, LLCInventors: Giuseppe Castaldi, Andrea Cusano, Vincenzo Galdi, Paolo Mattera, Roberto Parente, Joseph Minh Tien, Dustin Jeffery Gordon Krogstad, Riccardo DeSalvo, Yi Zhao

Patent number: 10013064Abstract: A haptic device configured to provide haptic feedback to a user. In one aspect, a user or part of a user is located on the haptic device including actuators and damping elements. A haptic feedback wave is generated by an actuator and propagated to the user or part of the user on the haptic device. Damping elements receive the haptic feedback wave and suppress the haptic feedback wave to reduce a reflection thereof.Type: GrantFiled: October 19, 2017Date of Patent: July 3, 2018Assignee: Oculus VR, LLCInventors: Sean Jason Keller, Tristan Thomas Trutna, Ravish Mehra, Christoph Omid Hohnerlein, Elia Gatti, Riccardo DeSalvo, David R.

Patent number: 9971410Abstract: An actuator configured to provide haptic feedback to a user. The actuator is located on a plate and is configured to apply various excitations to the plate to generate a mechanical wave propagating in the controlled direction. The excitations can be a translational motion of the actuator (or a portion of the actuator) in two or three perpendicular axes. Alternatively, the excitations can be a non-translational motion (e.g., rotation about an axis) of the actuator (or a portion of the actuator). By generating the mechanical wave traveling in the controlled direction, loss of energy due to scattering of the mechanical wave can be obviated.Type: GrantFiled: August 24, 2017Date of Patent: May 15, 2018Assignee: Oculus VR, LLCInventors: Sean Jason Keller, Tristan Thomas Trutna, Ravish Mehra, Christoph Omid Hohnerlein, Elia Gatti, Riccardo DeSalvo, David R.
