The program evaluates behavior of the actor in the environment, including measuring, analyzing and classifying actions and reactions of the actor in the simulation while the actor performs at least one predefined procedure in the environment; compares the behavior of the actor with a curriculum including at least one documented procedure and at least one documented performance value of the at least one predefined procedure; and outputs a qualification for the performance.

Embodiments of the invention provide devices and systems to monitor fullness of a patient's bladder. One embodiment of a bladder fullness (BF) measure system comprises a sensor device (SD) and a controller. The SD generates an output signal (OS) based on the force exerted by the bladder against SD the wherein the OS corresponds to a degree of BF. The SD may be attached to the bladder wall or adjoining tissue and positioned between the bladder and the pubic bone such that the SD is not affected by tissues force other than that from the bladder. The controller connects to the SD and causes an associated implant to perform a function when the SD output signal exceeds a predetermined threshold. Embodiments are particularly useful for providing information on BF to patients suffering from spinal injury or other conditions whereby they have lost the ability to sense BF and/or voluntarily urinate.

A medical imaging system is described that comprises an heating element configured to apply at least one heating pattern element to a material to locally heat the material; a sensor configured to capture the position of the heated material a predetermined time after the application of the heating pattern element; and circuitry configured to determine the change of the heating pattern applied to the material based upon the captured position of the heated material after the predetermined time.

A method of characterising tremor stability in a subject is described for a subject having an involuntary tremor symptomatic of a neurological disorder. The method comprising: identifying a series of tremor cycles from measured tremor data of the subject, said tremor cycles measuring periodic variation in movement of the subject due to the tremor; determining an instantaneous frequency for each tremor cycle and collating the instantaneous frequencies; determining an instantaneous variation between the instantaneous frequencies of each pair of adjacent tremor cycles within the series; comparing the instantaneous variation to the collation of determined instantaneous frequencies to determine a distribution of instantaneous variations; and determining an index value of the distribution of the instantaneous variations, said index value defining the stability of the tremor.

A PPG PRV device for generating a PRV parameter of a PPG signal (20) as an estimation of a HRV parameter of an ECG signal. The PPG PRV device employs a PPG probe (700) and a PPG PRV controller (710). In operation, the PPG probe (700) generate a PPG signal (20). In response thereto, the PPG PRV controller (710) generates a normalized PPG signal (20′) including a plurality of pulses of the PPG signal (20) designated as normal pulses by the PPG PRV controller (710) and excluding at least one pulse of the PPG signal (20) designated at least one abnormal pulse by the PPG PRV controller (710), wherein the normalized PPG signal (20′) is HRV comparable to the ECG signal. The PPG PRV controller (710) derives the PRV parameter from a HRV measurement of the normalized PPG signal (20′).

Methods, systems, and computer programs encoded on a computer storage medium, for improving EEG measurements by identifying artifacts present in EEG measurements and providing a real-time indication to a user of likely artifacts in EEG measurements are described. EEG measurements of a patient can be obtained by placing a wearable device or EEG cap on a patient's head. Sensors in the cap provide EEG data to a computing device that processes the data to identify one or more artifacts in the EEG data. The artifacts can be identified by conducting one or more operations of determining the signal to noise ratio of the line noise, calculating mutual information between sensor pairs, and applying the p-welch method. Based on the types of artifacts identified, the computing device can output an indicator that provides feedback to the technician performing an EEG test to make adjustments to the test setup.
