Patent number: 11519511Abstract: 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: November 19, 2021Date of Patent: December 6, 2022Assignee: Meta Platforms Technologies, LLCInventors: Sean Jason Keller, David R.

Patent number: 11029757Abstract: A wearable device (such as a glove or other control adapted to be worn on a portion of a body) includes multiple magnetic field generators at various locations on the wearable device and a magnetic flux sensor at a predetermined position relative to the wearable device. A position determines spatial positions of locations of the wearable device based on magnetic fields generated by various magnetic field generators and detected by the magnetic flux sensor. In some embodiments, the magnetic field generators have known positions relative to each other. Additionally, each magnetic field generator may generate a magnetic field in response to an input signal having a particular attribute, allowing the magnetic flux sensor to identify magnetic fields generated by different magnetic field generators.Type: GrantFiled: December 30, 2019Date of Patent: June 8, 2021Assignee: Facebook Technologies, LLCInventors: Ke-Yu Chen, Sean Jason Keller, David R.

Patent number: 11015926Abstract: A deformation sensing apparatus comprises a transmitter coupled to a propagation channel, and a receiver coupled to the same first end of the propagation channel. The propagation channel of the deformation is a transmission line, where a signal is transmitted by the transmitter and reflected signals are measured by the receiver responsive to the transmitted signals. A bend in the propagation channel results in a change in impedance of the transmission line at a location of the bend, resulting in a reflection of the signal from the location of the bend. The time delay of the reflected signals corresponds to the distance along the length of the channel where a bending of the propagation channel occurs. The amplitude of the reflected signal corresponds to a bend angle.Type: GrantFiled: August 15, 2019Date of Patent: May 25, 2021Assignee: Facebook Technologies, LLCInventors: Sean Jason Keller, Tristan Thomas Trutna, David R.
