Patent number: 11231779Abstract: A brain computer interface (BCI) module includes a flexible printed circuit assembly (FPCA) configured to conform to the head of a user. A plurality of emitters and a plurality of detectors are mounted on the FPCA. Each emitter of the plurality is configured to emit light towards the head of the user and each detector is configured to detect the emitted light. An array of ferrules is additionally mounted to the FPCA such that each ferrule of the array encases an emitter or a detector. The BCI module additionally includes a controller that is configured to receive an optical signal detected by a detector of the plurality and to encode the detected signal into a biological signal.Type: GrantFiled: August 21, 2020Date of Patent: January 25, 2022Assignee: Meta Platforms, Inc.Inventors: John Michael Sundberg, Frances Wing Yee Lau, E-Fann Saung, Ealgoo Kim

Patent number: 11011075Abstract: A haptic calibration device comprises a signal generator configured to receive the subjective force value and the force location from a subjective magnitude input device. The signal generator also receives from at least one of a plurality of haptic sensors a sensor voltage value, with the at least one of the plurality of haptic sensors corresponding to the force location. The signal generator stores the subjective force value and the corresponding sensor voltage value in a data store. The signal generator generates a calibration curve indicating a correspondence between subjective force values and sensor voltage values for the location where the subjective force was experienced using the data from the data store, wherein the calibration curve is used to calibrate a haptic feedback device.Type: GrantFiled: December 20, 2019Date of Patent: May 18, 2021Assignee: Facebook, Inc.Inventors: Ali Israr, Frances Wing Yee Lau, Freddy Abnousi, Keith Klumb

Patent number: 10867526Abstract: A haptic communication device includes an array of cutaneous actuators to generate haptic sensations corresponding to actuator signals received by the array. The haptic sensations include at least a first haptic sensation and a second haptic sensation. The array includes at least a first cutaneous actuator to begin generating the first haptic sensation at a first location on a body of a user at a first time. A second cutaneous actuator begins generating the second haptic sensation at a second location on the body of the user at a second time later than the first time.Type: GrantFiled: April 10, 2018Date of Patent: December 15, 2020Assignee: Facebook, Inc.Inventors: Ali Israr, Freddy Abnousi, Frances Wing Yee Lau

Patent number: 10854108Abstract: A haptic device comprises a signal generator that is configured to receive an input word that is a unit of a language. The signal generator converts the input word into one or more phonemes of the input word. The signal generator further converts the one or more phonemes into a sequence of actuator signals. The sequence of actuator signals is formed from a concatenation of sub-sequences of actuator signals. Each phoneme corresponding to a unique sub-sequence of actuator signals. The haptic device further comprises a two dimensional array of cutaneous actuators configured to receive the sequence of actuator signals from the signal generator, each of the actuator signals mapped to a cutaneous actuator of the two dimensional array of cutaneous actuators.Type: GrantFiled: April 10, 2018Date of Patent: December 1, 2020Assignee: Facebook, Inc.Inventors: Jennifer Chen, Frances Wing Yee Lau, Ali Israr, Venkatasiva Prasad Chakkabala, Robert Turcott, Siyan Zhao, Freddy Abnousi

Patent number: 10388186Abstract: A haptic communication device includes one or more cutaneous actuators to generate haptic vibrations corresponding to actuator signals received by the one or more cutaneous actuators. A dampening member, proximate to a body of a user wearing the haptic communication device, focuses the haptic vibrations at one or more distinct locations on the body. The dampening member has one or more first openings, wherein the one or more cutaneous actuators transmit the haptic vibrations to the one or more distinct locations through the one or more first openings. A spacing member contacts the dampening member and is separated from the body by the dampening member. The spacing member has one or more second openings dimensioned to receive and secure the one or more cutaneous actuators.Type: GrantFiled: April 10, 2018Date of Patent: August 20, 2019Assignee: Facebook, Inc.Inventors: Ali Israr, Pablo Castillo Canales, Frances Wing Yee Lau, Robert Turcott, Freddy Abnousi
