The enclosure includes a display coupled to the processor where the display is visible from an exterior of the enclosure; and a battery within the enclosure coupled to the processor and the display. The enclosure includes a probe tip coupled to an exterior of the enclosure. The probe tip includes first, second, and third sensor openings. A first distance between the first and second sensor openings is different than a second distance between the first and third sensor openings. The enclosure includes code stored in the memory where the code is executable by the processor, and includes code to receive first data associated with the first and second sensor openings, code to receive second data associated with the first and second sensor openings, and code to perform SRS using the first and the second data.

According to an aspect, there is provided an apparatus for use in detecting malingering by a first subject in a test of physical and/or mental function of the first subject. The apparatus comprises a memory unit configured to store a plurality of models, each model identifies a respective set of physical and/or mental function tests from a plurality of different physical and/or mental function tests that can be used to detect malingering in a subject and that meets one or more possible user requirements for detecting malingering; and a processing unit configured to receive a user input from a user of the apparatus, the received user input indicating a user requirement for detecting malingering in the first subject; following receipt of an indication that the first subject may be malingering in one or more physical and/or mental function tests, retrieve, from the memory unit, the identity of a first set of physical and/or mental function tests for a model that meets the indicated user requirement; and output a control signal to a function testing device indicating the retrieved identity of the first set of physical and/or mental function tests such that the testing device provides the identified first set of physical and/or mental function tests to the first subject completion for completion.

An intraoperative tissue oximetry device includes a tissue marker that includes one or more pens or one or more similar ink sources, such that the tissue marker can mark tissue according to oxygen saturation measurements made by the tissue oximetry device, thereby visually delineating regions of potentially viable tissue from regions of potentially nonviable tissue.

A notification control apparatus according to an embodiment includes: a reception unit that receives movement event information indicating that a movement event of a user has occurred; a schedule presence/absence determination unit that determines whether or not the user has a schedule immediately following or immediately preceding an occurrence time point of the movement event; a message generation unit that generates an advice to be notified to the user on the basis of the determination and the occurrence time point of the movement event; and a presentation unit that presents the generated advice to the user.

A method, a mobile device, and a computer program product for detecting loss of attention during play of media content in a mobile device. The method includes, during playback of first media content, receiving first data indicative of whether a consumer of the first media content is actively consuming the first media content. The method further includes evaluating, based on a comparison of the first data with comparative data, whether the first data indicates that the consumer is likely not currently paying attention to playback of the first media content. The method further includes identifying, based on a time of receipt of the first data that indicates that the consumer is not paying attention, a first time within the first media content at which the consumer stopped paying attention during the playback and resetting a playback location of the first media content to continue playback from the first time.

Systems and methods for detecting a traumatic brain injury (TBI). The system comprises a sensing arrangement and a control unit. The sensing arrangement collects eye movement data of a user. The control unit is in communication with the sensing arrangement and configured to compare the eye movement data to one or more baseline measurements of eye movement dynamics. The control unit is also configured to generate an alert indicating the presence or severity of the TBI for delivery to control unit administrator if the eye movement data diverges from one or more of the baseline measurements by a threshold amount.

A severity calculator analyzes patient information including a patient avatar and a patient state and along with a patient trajectory calculator, computes a predicted outcome which is used to administer treatment. The severity calculator systems and computer program products are also disclosed.

A method for determining oxygen saturation includes emitting light from sources into tissue; detecting the light by detectors subsequent to reflection; and generating reflectance data based on detecting the light. The method includes determining a first subset of simulated reflectance curves from a set of simulated reflectance curves stored in a tissue oximetry device for a coarse grid; and fitting the reflectance data points to the first subset of simulated reflectance curves to determine a closest fitting one of the simulated reflectance curves. The method includes determining a second subset of simulated reflectance curves for a fine grid based on the closest fitting one of the simulated reflectance curves; determining a peak of absorption and reflection coefficients from the fine grid; and determining an absorption and a reflectance coefficient for the reflectance data points by performing a weighted average of the absorption coefficients and reflection coefficients from the peak.

A wearable cardiac defibrillator (“WCD”) system may include a support structure that a patient can wear, an energy storage module that can store an electrical charge, and a discharge circuit that can discharge the electrical charge through the patient so as to shock him or her, while the patient is wearing the support structure. Embodiments may actively take into account bystanders, both to protect them from an inadvertent shock, and also to enlist their help. In some embodiments the WCD system includes a speaker system that transmits a sound designed to assist a bystander to perform CPR. Optionally CPR chest compressions received by the patient can be further detected, and feedback can be given. In embodiments, a WCD system may include a user interface that can be controlled to output CPR prompts tailored to a skill level of the bystander.
