Brainwave compatibility
11507924 · 2022-11-22 ·

A system and method for identifying individuals that compatibly contribute to high-performing teams is disclosed. Teams may range in size and complexity from a two-person team of roommates to many hundreds in a commercial product development team. Candidates for new or existing teams are identified by matching brainwave response of candidates to the brainwave signature of high-performing, compatible teams. The stimuli of stimulus datasets are rapidly presented to candidates and sensed by any of the five human senses. The signature of a team type is a set of brainwave response characteristics extracted from one or more high-performing, compatible exemplar teams presented with the stimulus dataset and is also distinctly different from other team types or the general population. Closeness of fit between a candidate's brainwave response and the signature of the exemplar team provides an indication of the likely compatible fit and contribution of a candidate to a high-performing team.

IMAGING-BASED REFLEX MEASUREMENTS FOR SEDATION DEPTH MONITORING
20220361809 · 2022-11-17 ·

The present invention relates to sedation assessment. In order to facilitate sedation depth monitoring in an autonomous imaging setting, it is proposed to use the imaging modality itself to measure the response to suitable reflexes in order to determine the depth of sedation wherein suitable reflexes include, but are not limited to, the pupil reflex, so-called superficial reflexes and the withdrawal reflexes. In one embodiment, the pupil reflex may be measured in an MRI system by repeated interleaving of dedicated iris MR imaging with the conventional scan protocol. In another embodiment, superficial reflexes in response to stroking of the skin may be measured. This may involve a dedicated actuator that may be closely integrated with the imaging modality, e.g. an MR receive coil applied to the patient. Alternatively, remote haptic systems may be used. The reflex is then acquired with a suitable diagnostic imaging method. In another embodiment, the withdrawal reflex in response to pain may be measured. This may involve an actuator that induces sudden stitching pain or very local temperature-induced pain and that is closely integrated with the imaging modality, e.g. a pinching device integrated with a patient support or an MR receive coil applied to the patient. The reflex is then acquired with a suitable diagnostic imaging method.
