An example device for detecting one or more parameters of a cardiac signal is disclosed herein. The device includes one or more electrodes and sensing circuitry configured to sense a cardiac signal via the one or more electrodes. The device further includes processing circuitry configured to determine an R-wave of the cardiac signal and determine whether the R-wave is noisy. Based on the R-wave being noisy, the processing circuitry is configured to determine whether the cardiac signal around a determined T-wave is noisy. Based on the cardiac signal around the determined T-wave not being noisy, the processing circuitry is configured to determine a QT interval or a corrected QT interval based on the determined T-wave and the determined R-wave.

An intelligent defecation device for living creature includes a device body, a supporting portion, an image module, and a first analysis module. The supporting portion is formed within the inner side of the device body for accommodating a moisture absorption member so as to allow the living creature to leave over its excrement therein. The image module is also arranged at the device body for dynamically capturing the images of the excrement in the supporting portion and outputting the image. The first analysis module is arranged in the device body and connected with the image module to analyze and calculate the defecation mode with the image based on preset or accumulated data, so as to generate a signal when an abnormal defecation mode is diagnosed.

Embodiments provide for systems and methods for modulating activity of a live neuronal circuit within the brain of a mammal. In one example, a method comprises applying a focused microwave pulse to a focal spot corresponding to the live neuronal circuit, while simultaneously monitoring a brain image produced by a brain imaging system. In this way, the focused microwave pulse may be used to transiently modulate the function of the live neuronal circuit, as guided by anatomical and functional information provided via the brain imaging system, useful for both research purposes and for treating psychiatric, neurological and neuroendocrine disorders.

A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual articulation mechanism to articulate a jaw assembly coupled to a reload shaft connected to the handle. The manual articulation mechanism can include a ball screw mechanism that translates an articulation member responsive to rotation of an articulation knob. The articulation mechanism includes a release function that allows the jaw assembly to return to a longitudinally centered orientation. The powered handle includes a battery pack serving as a power supply for the drive system. A control system can control actuation of the motor based on user inputs and operating parameters of the stapler. The powered handle can include a manual return mechanism.

It is disclosed an apparatus for restoring voluntary control of locomotion in a subject suffering from a neuromotor impairment comprising a multidirectional trunk support system and a device for epidural electrical stimulation. The robotic interface is capable of evaluating, enabling and training motor pattern generation and balance across a variety of natural walking behaviors in subjects with neuromotor impairments. Optionally, pharmacological cocktails can be administered to enhance rehabilitation results. It is also disclosed a method for the evaluation, enablement and training of a subject suffering from neuromotor impairments by combining robotically assisted evaluation tools with sophisticated neurobiomechanical and statistical analyses. A method for the rehabilitation (by this term also comprising restoring voluntary control of locomotion) of a subject suffering from a neuromotor impairment in particular partial or total paralysis of limbs, is also disclosed.

A medical device is configured to receive sensed cardiac event data including a value of a feature determined from each one of a plurality of cardiac events sensed from a cardiac signal according to a first setting of a sensing control parameter. The medical device is configured to classify each value of the feature of each one of the sensed cardiac events as either a predicted sensed event or a predicted undersensed event according to a second setting of the sensing control parameter that is less sensitive to sensing cardiac events than the first setting. The medical device is configured to determine a predicted sensed event interval between each consecutive pair of the predicted sensed events and predict that an arrhythmia is detected or not detected based on the predicted sensed event intervals.

A fluid ejection device which ejects a fluid includes: an ejection tube which ejects the fluid; a fluid chamber which communicates with the ejection tube; a piezoelectric element capable of changing a volume of the fluid chamber; a controller which controls a drive voltage applied to the piezoelectric element; and a fluid supplying unit which supplies the fluid to the fluid chamber at a predetermined flow rate. If a maximum frequency available to be set of the drive voltage is fmax [Hz] and an amount of change in the volume of the fluid chamber when a maximum value available to be set of the drive voltage is applied to the piezoelectric element to drive the piezoelectric element is V1 [ml], the fluid supplying unit supplies the fluid at the predetermined flow rate above V1×fmax [ml/s].

The invention disclosed here is sensor technology incorporating a closed-loop mathematical model of a cardiovascular system, for detection and/or monitoring of a cardiovascular status of a test subject. The closed-loop cardiovascular model equates common circuit components with real-world cardiovascular parameters, and is capable of tracking and/or predicting cardiovascular behavior.

Variations in pulse shape over time can be used to draw inferences about activity, health, and age of an individual. For example, PPG pulses may be mapped to a latent space where variations in shape can be measured directly in terms of distance between pulses. In one aspect, pulse-to-pulse comparisons for an individual can be used to estimate strain, recovery, sleep, and so forth. Longer term measurements (e.g., over weeks, month, or years) can be used to detect changes in health and fitness for the individual. In another aspect, pulse-to-pulse comparisons among different individuals can be used to estimate relative cardiovascular health, age, and the like.
