Systems and methods of controlling a device using detected changes in a neural-related signal of a subject are disclosed. In one embodiment, a method of controlling a device or software application comprises detecting a first change in a neural-related signal of a subject, detecting a second change in the neural-related signal, and transmitting an input command to the device upon or following the detection of the second change in the neural-related signal. The neural-related signal can be detected using a neural interface implanted within a brain of the subject.

Disclosed here are devices, methods and systems for sensing electrical activity from one or more neural regions of a subject is disclosed, the method comprising: advancing a device to or through a blood vessel in the subject, where the device comprises an electrode array having a plurality of electrodes; detecting an electrical signal of a subject via the plurality of electrodes, where the plurality of electrodes are spaced apart on the electrode array such that the plurality of electrodes are each configured to record distinct electrical signals from each of the one or more neural regions; and analysing the distinct electrical signals using a control unit.

A system and method for providing haptic feedback in a virtual environment generates virtual instances, such as game levels, and interactions within those virtual instances. The interactions include a first interaction parameter and may be events, such as explosions, within the virtual instance. The system determines the spatial relationship between the player avatar and the interactions and identifies the environment between the player avatar and the interactions. A complete state, including the virtual instances and interactions, is generated. Based at least partially on the complete state, at least one actuator command is generated and sent to a wearable haptic rig. The at least one actuator command is applied to at least one haptic motor of the wearable haptic rig to activate at least one haptic motor and provide haptic feedback to the player.

The invention relates to a device with a vibration-damping interchangeable head that facilitates the dining experience of Parkinson's patients who tremble their hands. The device works with a passively controlled system and minimizes the trembling of their hands when using utensils such as spoons and forks that they hold while eating.

A cosmetic securement device for stabilization and alignment of a cosmetic applicator, comprising, a handle; an adapter coupled to a first end of the handle; a holder connected to a first end of the adapter; a first sensor positioned within the handle to determine a first positional measurement of the cosmetic securement device; a second sensor positioned within or proximate the adapter to determine a second positional measurement of the cosmetic securement device; and a control circuitry positioned within the handle and in communication with the first and second sensor, and the motor, the control circuitry configured to determine an angle of the cosmetic securement device based on the first and the second positional measurement, and in response to a determination that the angle of the cosmetic securement device comprises a selected angle, orient the holder based on the first positional measurement and the second positional measurement via a motor.

Eating aid characterized in that it is inserted into an arm lifter via an extension rod and hangs from this extension rod at a ball joint below the hand.

A weightlifting device with a customized forearm brace, including elements of the customization of the device is provided. The device effectively grips a weight in lieu of a hand, thereby enabling people with upper extremity (hand, wrist, or finger) injuries, deformities, amputations and any other related afflictions to circumnavigate their ailment(s) and engage in weightlifting exercise.

Method for operating a haptic feedback device for persons to perceive the environment as an orientation aid and to direct attention to dangerous situations by means of haptic information elements and to trigger a tactile stimulus in conjunction with shape memory elements (4) characterized by that in a first process step, at least one shape memory actuator (2, 12) in conjunction with a tactile information element (3, 13, 14, 15) and in conjunction with at least one shape memory element (4) designed as an actuating element causes the corresponding shape memory actuator (2, 12) to perform a linear movement of the respective tactile information element (3, 13, 14, 15) by heating it, to press against a contact point of a user or at a human-machine interface to trigger the tactile stimulus, and that in further process steps, the actuation speed of the tactile information elements (3, 13, 14, 15) is adjusted to haptic information, the penetration depth of the tactile information element(s) (3, 13, 14, 15) is continuously changed depending on the haptic information, and the position and / or force of the pressure of the tactile information elements (3, 13, 14, 15) on the contact point of a person or at the human-machine interface is measured when the tactile stimulus is triggered by a sensor or by a change in the intrinsic resistance of the shape memory element (4) during the crystalline transformation takes place. that in order to achieve a combination of tactile and vibrotactile information, the movement of the shape memory element (4) is superimposed by at least one further movement of the shape memory element (4), and the further movement takes the form of a linear movement offset by 90° or an oscillating movement, or that by combining an penetrating movement with a second movement to change the position of the corresponding tactile information element (3,13,14,15) on the skin, an alternating movement of tactile information elements (3,13,14,15) and elements within an array takes place. and that in a final process step, when the shape memory element (4) cools down, the tactile information elements (3, 13, 14, 15) are returned to their initial position.

A mouth-operated control device comprising an arched casing (10) configured for at least part of the casing (10) to be arranged between a maxillary dentition and a mandibular dentition of the user in an operating position, a first at least bidirectional input interface (21) housed in the concave region of the casing (10) and accessible to the tongue of the user; a second at least bidirectional input interface (22) in the part of the casing (10) intended for being arranged between the maxillary dentition and the mandibular dentition selected to be arranged facing the mandibular dentition of the user, allowing the operation thereof with the relative movement between the maxillary dentition and the mandibular dentition of the user; and a control electronics (30) connected to all the input interfaces (21, 22, 23) for the transmission of control signals to an external device.

An assistance method for assisting a person in grasping or otherwise manipulating an object includes receiving video of a hand of the person and of an object. An intent to grasp the object is identified based on proximity of the hand to the object in the video or as measured by a proximity sensor, or using gaze tracking, or based on measured neural activity of the person. The object and the hand in the video are analyzed to determine an object grasping action for grasping or otherwise manipulating the object. An actuator is controlled to cause the hand to perform the determined hand action for grasping or otherwise manipulating the object.
