Abstract: Damping assemblies for heat sinks and related methods are disclosed. An example apparatus includes a chassis; a first heat sink associated with an electronic component in the chassis; a second heat sink coupled to the first heat sink, the second heat sink spaced apart from the first heat sink in the chassis; and damping material proximate to the second heat sink.

Abstract: This disclosure relates to analyzing effect of a secondary cognitive load task on a primary executive task. Human random sequence generation is a marker to study cognitive functions and inability to generate random sequences (RS) can reveal underlying impairments. Traditionally, ‘call out’ or ‘write down’ procedures are used to obtain human generated numbers, wherein short term memory and number of previously generated entities visible to a subject plays a major role. Also precise trial-wise or response-wise analysis may not be possible. In the present disclosure, the human generated random numbers are digitized into RS and a cognitive load (CL) inducing task is imposed on the executive task. The CL demanding task disrupts randomization performance. Deviation from randomness, load index based on gaze data and deviation from pupillometry data of healthy subjects are provided as indicators of an interference effect imposed by the CL and thereby indicative of underlying impairments.

Abstract: A system and method for detection and analysis of learner's/performers cognitive flow have been provided. The system is configured to measure the cognitive state of the performer, while they are performing tasks of various complexity levels, using physiological responses like brain activation, heart rate variability and galvanic skin response. The system uses a Bayesian network based framework to probabilistically evaluate the cognitive state of the learner from the difficulty levels of the tasks, IQ level of the learner and observations made using the physiological sensing. The system also measures the actual cognitive state using a questionnaire. The predicted cognitive state and the actual cognitive state is compared and based on the outcome of comparison a relevant step is taken.

Abstract: Metacognitive confidence is defined as the confidence generated from the observation and critical analysis of one's own the decision making process. There are various studies indicative of the importance of measurement of confidence level of the person while doing a task. The existing confidence level measurement methods provide various limitations such invasive and complex experimental setup, noise and artifacts in the signal. A system and method for determining confidence level of a person using electroencephalogram has been provided. The system is configured to build a metric to determine the amount of metacognitive confidence, in presence of different cognitive load condition, directly from brain activity using electroencephalogram signals. The brain activity acquired from the frontal and temporal part of the brain at different frequency bands and combined with suitable weights to form the confidence metric.

Abstract: A system for removing heat from an electronic component associated with an information handling system is disclosed. The system may comprise a mass providing a heat sink to the electronic component and a set of extended surfaces for transferring heat from the mass. The set of extended surfaces may define a primary flow direction for a cooling fluid. A first subset of the set of extended surfaces may have a first length measured in the primary flow direction. A second subset of the set of extended surfaces may have a second length measured in the primary flow direction. Each of the first and second subsets of extended surfaces may include one or more extended surfaces. The second subset of extended surfaces may be generally proximate the hotspot of the electronic component. The second length may be less than the first length such that the flow rate of the cooling fluid through the second subset of extended surfaces is greater than a flow rate of the cooling fluid through the first subset of extended surfaces.

Abstract: A system for mounting an electronic component associated with an information handling system is disclosed. The system may comprise a carrier configured to carry an electronic component and a caddy configured to mount the carrier and the electronic component to a structure of the information handling system. The carrier may include a mass providing a heat sink to the electronic component and one or more fins for transferring heat from the mass. The carrier and the caddy may operate in conjunction as a damper to attenuate vibration.
