  • Patent number: 11213732
    Abstract: An omnidirectional treadmill platform includes a splicing floor, an omnidirectional driving base and a floor removing/splicing actuator. A plurality of omnidirectional wheels are arranged in the driving base. The splicing floor is placed on the omnidirectional wheels. A user moves on the splicing floor, and the omnidirectional wheels of the driving base cause the splicing floor to move in a direction Opposite to the movement direction of the user thus enabling the user to experience unlimited free movement, while in reality remaining in place. The splicing floor is formed by splicing a plurality of splicing blocks. The floor removing/splicing actuator removes and splices the splicing blocks at right positions, recycling splicing blocks and achieving the unlimited extension of the splicing floor. The new platform provides unrestricted movement and variable ground surface simulation irrespective of turn radius with near-negligible inertia force without the use of special footwear.

  • Patent number: 10854108
    Abstract: 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.

  • Patent number: 10474684
    Abstract: A sensor data system, method and computer program configured to handle sensor data are disclosed. The system includes a reception unit adapted to receive sensor data, a storing unit adapted to store at least some of the received sensor data in an observations database, a recording unit adapted to record usage of the sensor data, and a relevance determination unit adapted to determine the relevance of the sensor data based on the recorded usage. A decision unit is adapted to remove excess sensor data with determined relevance below a limit from the observations database, and to retain relevant sensor data with determined relevance above the limit in the sensor database. Sensor data in an observations database may thereby be limited to a desired size, by removal of excess sensor data from the database.

  • Patent number: 10297120
    Abstract: A haptic effect generation system includes a computing platform including a hardware processor, an analog-to-digital converter (ADC), a digital-to-analog converter (DAC), and a memory storing a haptic software code, as well as a haptic transformer coupled to the computing platform. The haptic transformer receives an input signal, and transforms the input signal to a first audio signal corresponding to the input signal. The ADC converts the first audio signal to a first audio data. The hardware processor executes the haptic software code to receive the first audio data from the ADC, and to generate a second audio data using the first audio data, the second audio data corresponding to a desired haptic effect. The DAC converts the second audio data to a second audio signal. The haptic transformer then transforms the second audio signal to a haptic actuator signal for producing the desired haptic effect.

  • Patent number: 9588588
    Abstract: There is provided a system and method for producing a haptic effect. In one implementation, such a system includes a system processor, a system memory, and a haptic engine stored in the system memory. The system processor is configured to execute the haptic engine to receive a media content, to map an event contained in the media content to a predetermined haptic effect, and to display an interface enabling a system user to produce a customized haptic effect based on the predetermined haptic effect. The system processor is further configured to generate an output data for causing one of the predetermined haptic effect and the customized haptic effect to occur.
