Abstract: Introduced here are teaching system for realistically simulating medical situations in such a manner to test individuals as to the adequacy of their learning. A teaching system may include a manikin representative of a patient, an image projection mechanism, a simulation mechanism, a headpiece, a pair of hand coverings, a controller, a performance review mechanism, a recording device, a scenario generation mechanism, or any combination thereof. The teaching system can improve upon conventional simulation in several respects. First, the script corresponding to a simulation session may be dynamically traversed to mimic the unpredictability of an actual medical situation. Second, the action(s) of an individual may be actively monitored to discover whether her behavior complied with the relevant protocol(s).

Abstract: Introduced here are approaches for capturing and recording medical event details during cardiopulmonary resuscitation (CPR) events and other emergency medical events. A recording begins when an operator inputs a request to initiate recording. The operator may use a recording system with a combination of input devices to record medical actions. The recording system acknowledges the operator's actions by various means which may include icons displayed for the operator. The operator's interactions with the icons indicate corresponding actions observed by the operator, which are recorded as a log of the actions in temporal order that serves as a non-transient record of the medical event. An analysis of the recorded details of the medical event, by comparing the actions to prescribed actions in one or more professional standards, can provide an assessment of the actions taken.

Abstract: Methods and systems for selecting electrical stimulation parameters for an electrical stimulation device implanted in a patient can use an iterative process for identifying electrodes for stimulation, as well as suitable stimulation parameters. The process begins with an initial set of electrode combinations to identify regions of the nerve or other tissue for stimulation. This leads to selection of other electrode combinations to test, followed by the selection of multiple electrode groups (which can include three or more electrodes) for stimulation.

Abstract: An example of a system for modulating blood pressure may include a blood pressure monitoring circuit, a blood pressure modulation device, and a control circuit. The blood pressure monitoring circuit may be configured to sense signals and generate one or more blood pressure parameters indicative of the blood pressure and/or a vascular resistance and one or more activity parameters indicative of an activity level and/or a postural change using the sensed signals. The blood pressure modulation device may be configured to deliver a therapy modulating the blood pressure. The control circuit may be configured to control the therapy using therapy parameters, receive the one or more blood pressure parameters and the one or more activity parameters, analyze changes in the one or more blood pressure parameters that are correlated to changes in the one or more activity parameters, and adjust the therapy parameters using an outcome of the analysis.

Abstract: Embodiments relate to sending vertical synchronization data for a plurality of data streams in a selected data stream to perform authentication operations for the plurality of data stream. A port processor receives data streams from a plurality of transmitting devices. After receiving the data streams, the port processor selects one of the data streams for transmission to a decrypting device. The port processor extracts vertical synchronization data from the unselected data streams and inserts the extracted vertical synchronization data into the selected data stream to form a modified data stream. The port processor sends the modified data stream to a decrypting device. The decrypting device has at least one processing engine. The port processor discards the unselected data streams without sending the unselected data streams to the decrypting device.
