Abstract: A system for performing deep brain stimulation on a brain of a patient is disclosed. The system comprises one or more recording arrays, at least one stimulation array, and a processor. The recording arrays, which may be minimally invasively inserted to a target recording site of the brain, include recording electrodes having a diameter of less than about 1 mm and having a spacing of less than about 1 mm therebetween. The stimulation array, which may be inserted to a target stimulation site within the deep brain, includes at least one stimulation electrode. The processor is configured to receive one or more recorded signals from the recording arrays at the target recording site, determine a neurological state of the brain based on the recorded signals, and deliver electrical stimulation to the target stimulation site through the stimulation array based on the neurological state in order to electrically stimulate the brain.

Abstract: A systems and methods for calibrating a neural device using transfer learning techniques. The methods can include aggregating calibration data across a user population to define a global dataset, identifying similar data segments across the global dataset to define a task-independent training dataset, training a feature extraction model based on the task-independent training dataset to define a trained, task-independent feature extraction model, receiving the calibration data from a user calibrating the neural device, and calibrating a user-specific feature extraction model using the trained, task-independent feature extraction model and the calibration data.

Abstract: A system for performing spinal cord stimulation on a subject is disclosed. The system comprises one or more recording arrays, at least one stimulation array, and a processor. The recording arrays, which may be minimally invasively inserted to a target recording site of the brain, include recording electrodes having a diameter of less than about 1 mm and having a spacing of less than about 1 mm therebetween. The stimulation array, which may be minimally invasively inserted to a target stimulation site within the nervous tissue, includes stimulation electrodes. The processor is configured to receive more recorded signals from the recording arrays at the target recording site, determine an electrophysiological state of the brain based on the recorded signals, and deliver electrical stimulation to the target stimulation site through the stimulation array based on the determined electrophysiological state in order to affect the electrophysiological state.

Abstract: Disclosed herein are systems and methods for neural interfaces. Neural interfaces may form minimally invasive and high-scalable bidirectional brain-computer interfaces, which may be used in the treatment of a variety of disorders of the brain and nervous system. Disclosed are methods for a minimally invasive technique for implanting neural interfaces, a neural interface configured to be placed between the brain and the dura and configured to record from and/or stimulate the cortical surface. Also disclosed are methods for attaching a plurality of microelectrode arrays to form a neural interface device, and fabricating neural interfaces including microelectrode arrays and pockets to facilitate their insertion. The disclosed systems and methods also include neural decoding techniques.

Abstract: This invention describes a tactical advanced robotic engagement system (ARES) (100) for combat or rescue mission by employing advanced electronics, AI and AR capabilities. In ARES, a user carries a weapon or tool (102) equipped with a hand-operable controller (150) for controlling an associated UGV (170), UAV (180) or UUV. The UGV (170) provides a ground/home station for the UAV (180). The UGV, UAV is equipped with a camera (290) to obtain real-time photographs or videos and to relay them to a heads-up display (HUD) (110) mounted on the user's helmet (104). The HUD (110) system provides intuitive UIs (132) for communication and navigation of the UGV, UAV; AR information reduces visual cognitive and mental loads on the user, thereby enhancing situation awareness and allowing the user to maintain heads-up, eyes-out and hands-on trigger readiness. The HUD (110) also provides intuitive UIs to connect up with peers and/or a Command Centre (190).

Abstract: An air turbine starter includes a starter housing and a check valve. The check valve is disposed within the starter housing and is configured, in response to a pressure differential across the check valve, to selectively allow and prevent lubricant to flow therefrom. The check valve includes a valve includes a valve body, a valve seat, a valve bore, a valve element, and a plurality of rounded grooves. The valve bore is formed in the valve body between the valve seat and the lubricant outlet port. The valve element is disposed within the valve bore and is movable between a plurality of open positions and a closed position. The rounded grooves are formed in the valve body, and are disposed adjacent to, and in fluid communication with, the valve bore to improve lubricant to flow past the valve element when the valve element is in an open position.

Abstract: A method for determining the comparability of at least two bonds is provided and includes the steps of identifying a plurality of factors and determining a value for each of said plurality of factors for each of the at least two bonds. Next, a covariance matrix is formed where the covariance matrix includes a weighting factor for each of the plurality of factors and where each of the weighting factors relate to an amount of market activity attributed to the corresponding one of the plurality of factors. Finally, the comparability of the at least two bonds is determined based on the values for each of the at least two bonds and the covariance matrix.
