A first acquisition unit acquires the current position of a carriage unit as information regarding the travel environment of the carriage unit. A second acquisition unit acquires a first upper limit value of the travel speed as appropriate travel conditions of the carriage unit corresponding to the current position acquired by the first acquisition unit. A third acquisition unit acquires a first measurement value of the travel speed as information regarding the travel state of the carriage unit. A travel state correction controller performs travel state correction control to make a correction to a travel state satisfying the appropriate travel conditions in a case where the travel state acquired by the third acquisition unit deviates from the appropriate travel conditions acquired by the second acquisition unit. That is, the travel state correction controller reduces the travel speed of the carriage unit in a case where the first measurement value exceeds the first upper limit value.

The second device may be configured to cause the second device to display a message requesting confirmation that the second device displayed the message and determine whether the second device receives the requested confirmation that the second device displayed the message.

A pulse wave analyzing apparatus comprises an acquiring section (11) which acquires a pulse wave that is non-invasively measured, and an analyzer (12) which calculates data on the frequency axis by using the pulse wave, and which obtains the index value of the respiratory-induced variation based on the calculated data on the frequency axis.

A method for performing a medical procedure, includes coupling a tip of a probe to tissue in an organ of a patient in order to apply the medical procedure using the probe. A force exerted by the tip on the tissue and a displacement of the tip created by the force are measured. A dependence of the force on the displacement is calculated. Based on the calculated dependence, a risk level of perforation of the tissue is estimated.

Sensor systems, transdermal analyte monitoring systems (TAMS), and methods of improving analyte detection are described herein. The sensor systems have two working terminals, at least one counter terminal, and optionally one or more reference terminals. The first working terminal measures electrical signals due to an analyte level along with background interferences. The second working terminal measures only background interferences. The transdermal analyte monitoring systems include the sensor system and a computing device. The computing device performs mathematical analysis using an appropriate algorithm on the electrical information provided by the electrodes of the sensor system to obtain an accurate analyte level. Typically, the second electrical signal is subtracted from the first electrical signal to obtain an accurate analyte level in real time.

The application provides a method, system for registration of a bone, and a trackable element, it is configured to obtain a mark point information which can be obtained from a certain operation performed by a distal end of a trackable element on a surface of the bone when a switch of the trackable element meets a setting condition corresponding to the operation; and to perform a virtual reconstruction of the surface of the bone according to the obtained mark point information and an image data of the bone which is obtained in advance. As a result, a precise registration of the patient's physical space coordinate system and image space coordinate system can be achieved, during which only one operator is enough for completing the registration. Therefore, operations with high accuracy and convenience are ensured, which can significantly improve the registration efficiency, and the operating experience of operators.

Technologies for monitoring impaction and predicting impaction state during an orthopaedic surgical procedure include one or more impaction sensors that generate sensor data. The surgical procedure includes impaction of an orthopaedic implement such as a surgical instrument or a prosthetic component. An impaction analyzer generates an impaction state prediction with a machine learning model based on the sensor data. The impaction state prediction may include an unseated state, a seated state, and a fracture state. An impaction state user interface outputs the impaction state prediction. A model trainer may train the machine learning model with labeled sensor data.

The invention provides a system for monitoring a fetus in a pregnant woman, and/or the maternal health risk for pregnancies complicated by such as pre-eclampsia and hypertensive disorders. The system comprises a portable or wearable unit that can be worn by the pregnant woman, preferably so as to allow monitoring during daily life, e.g. in the form of an adhesive patch. The portable unit has a sound sensor, e.g. a microphone or accelerometer, to be positioned on the skin of the abdominal area of the pregnant woman so as to detect a vascular sound from umbilical arteries of the fetus or from the uterine arteries of the pregnant woman. The sound sensor is functionally connected to a processing unit which executes a processing algorithm on the captured vascular sound and extracts a signal parameter accordingly, e.g. the Pulsatility Index. The processing unit then communicates the signal parameter, e.g. using an audio signal, a visual display or by means of a wired or a wireless data signal. Some embodiments include one or more additional sensors, such as a sensor for detecting fetal electrocardiographic signals, and/or a sensor for detecting uterus electromyographic activity. Especially, the sound sensor and such additional sensor(s) may be arranged within one adhesive patch or several adhesive patches.
