  • Publication number: 20240144066
    Abstract: In some aspects, the techniques described herein relate to a quantum method for solving a second-order cone program (SOCP) instance, the method including: defining a Newton system for the SOCP instance by constructing matrix G and vector h based on the SOCP instance; preconditioning matrix G and vector h via row normalization to reduce a condition number of matrix G; iteratively determining u until a predetermined iteration condition is met, the iterations including: causing a quantum computing system to apply matrix G and vector h to a quantum linear system solver (QLSS) to generate a quantum state; causing the quantum computing system to perform quantum state tomography on the quantum state; and updating a value of u based on a current value of u and the output of the quantum state tomography; and determining a solution to the SOCP instance based on the updated value of u.

  • Patent number: 10295823
    Abstract: The present disclosure pertains to various embodiments of optical stimulation systems that may be configured to generate a stimulation beam capable of inducing a cutaneous sensation in a user. A position tracking system associated with the stimulation system may be configured to track a position of at least one target stimulation area. A controller may be configured to generate a control signal to selectively activate the stimulation system and to receive the position of at least one target stimulation area from the position tracking system. A beam steering system may be configured to receive input from the controller and configured to direct the stimulation beam toward the at least one target stimulation area based on the input from the controller.

  • Patent number: 10037661
    Abstract: Disclosed herein are a variety of multimodal sensory stimulation systems and related methods for providing multimodal sensory experiences to users. In various embodiments, a multimodal sensory stimulation may be configured to provide a tactile sensation using an optical stimulation system. The output of the optical stimulation system may selectively directed onto a target area of skin of the user to induct a tactile representation of a simulated object. A multimodal sensory component may provide a component in communication with the controller and configured to selectively deliver a multimodal sensory representation of the simulated object. In various embodiments, the multimodal sensory component may be configured to display a visual representation of the simulated object or to generate an aural representation of the simulated object. The sensory modalities may be adapted in time and intensity to create a sensory experience associated with the simulated object.

  • Publication number: 20170308170
    Abstract: The present disclosure provides various systems and methods for inducing cutaneous sensations by delivering electromagnetic radiation to directly or indirectly excite neural tissue. An electromagnetic radiation source, such as one or more infrared lasers, may be used to transcutaneously excite neural tissue. The excited neural tissue may be interpreted by the user's nervous system as cutaneous sensations. Accordingly, a system as described herein may be used to induce sensations to allow actual cutaneous sensations to be simulated. A system for inducing a cutaneous sensation via transcutaneously focused electromagnetic radiation may be incorporated in a display to provide cutaneous sensation feedback or used as a separate accessory component associated with a display. Numerous additional applications and variations are provided herein.

  • Publication number: 20170011603
    Abstract: Disclosed herein are a variety of systems and methods for eliciting cutaneous sensations using electromagnetic radiation. In one embodiment, an optical stimulation system is configured to induce a cutaneous sensation in a user of an electronic device based upon a tactile application executable on the electronic device. The optical stimulation system may include an interface component configured to selectively direct the output of the stimulation system onto a target area of skin of the user. A controller may be configured to generate a control signal to cause the stimulation system to modify one or more characteristics of the output of the stimulation system in order to induce a cutaneous sensation based on detection of a registration mark associated with tissue to be stimulated, a representation of a simulated object, and a stimulation profile representing the simulated object.
