Abstract: An augmented reality system obtains sensor data depicting a first object in a scene. The identity of the first object is determined. The system estimates a size of the first object based on the determined identity. Based on the estimated size, the system estimates a scale of other objects depicted in the obtained sensor data. An augmented reality display is generated based at least in part on the size of a second object determined using the estimated scale.

Abstract: In various embodiments, a first classification assigned to a periodic component of an electrical waveform that represents electrical activity in a patient's heart may be identified (302). A corresponding periodic component of a hemodynamic waveform that represents hemodynamic activity in the patient's cardiovascular system may be analyzed (306, 318, 328). The corresponding periodic component may be causally related to the periodic component of the electrical waveform. Based on the analysis, the previously-assigned classification may be assigned (312, 324) to the corresponding periodic component of the hemodynamic waveform in response to a determination, based on the analyzing, that the previously-assigned classification also applies to the corresponding periodic component.

Abstract: An electrocardiogram diagnostic system (30) having a non-athletic ECG diagnostic mode and an athletic ECG diagnostic mode. The electrocardiogram diagnostic system (30) employs an electrocardiogram wave controller (30) and an electrocardiogram diagnostic controller (50). In operation, the electrocardiogram wave controller (30) generates an ECG wave responsive to one or more electrode signals. In response thereto, the electrocardiogram diagnostic controller (50) classifies the ECG wave as either a non-athletic ECG wave or an athletic ECG wave, interprets a non-athletic classified ECG wave based on non-athletic ECG diagnostic criteria as either a normal non-athletic ECG wave or an abnormal non-athletic ECG wave, and interprets an athletic classified ECG wave based on athletic ECG diagnostic criteria as either a normal athletic ECG wave or an abnormal athletic ECG wave.

A cursor is positioned proximate to a first object in response to a first gesture. A selected state of the first object is determined in response to a second gesture. A visual indication of the selected state of the first object is displayed by the augmented reality device. A second position for the cursor, proximate to a second object, is determined. A visual indication of the first object's selected state remains displayed after the cursor is moved to be proximate to the second object.
