Abstract: Disclosed is the measurement, identification, knowledge inference and notification alerting of fevers within individuals. Embodiments according to the present disclosure include a system for measuring at least two body temperatures. The first temperature is measured from a body region that correlates with deep body temperature; the second is measured from body regions capable of subcutaneous/deep tissue vasoconstriction. Temperatures of the first region are automatically compared to cutoff thresholds, and differences between the first and second regions are automatically compared to temperature difference thresholds. This apparatus automatically evaluates if none, one, or both thresholds have been exceeded. If none or one, then a subject can be identified as normal (afebrile). If both thresholds are exceeded a screening or test subject identified as febrile, where actions can be taken to isolate individuals to prevent spreading of communicable diseases.

Abstract: An ultrasound signal processing device performs transmission events by an ultrasound probe having transducer elements, generates a sub-frame acoustic line signal for each transmission event based on reflected ultrasound, and synthesizes sub-frame acoustic line signals to generate a frame acoustic line signal. A transmitter causes the ultrasound probe to transmit ultrasound beams to an ultrasound main irradiation area. A receiver generates receive signals for the transducer elements. A delay-and-sum calculator sets a target area in the ultrasound main irradiation area, and performs delay-and-sum calculation with respect to the receive signals from measurement points in the target area to generate a sub-frame acoustic line signal. The target area has, in a depth range shallower than a focal point, a width in the transducer element array direction that decreases as the depth decreases. A synthesizer synthesizes sub-frame acoustic line signals.

Abstract: For rotation compensation in a catheter, a rotation sensor senses rotation of the handle or catheter. Motors are controlled to change the bend in response to sensed rotation. As the tip rotates due to handle rotation, the motors change the bend to maintain the bend and tip position relative to the patient. This steering in the patient reference frame may be more intuitive, easier to learn, and allow rotation to change an imaging field of view without moving the bending planes.
