(2020)
The invention relates to an oesophageal electrode probe (10) for bioimpedance measurement and/or for neurostimulation; a device (100) for transoesophageal cardiological treatment and/or cardiological diagnosis; and a method for the open-loop or closed-loop control of a cardiac catheter ablation device and/or a cardiac, circulatory and/or respiratory support device. The oesophageal electrode probe comprises a bioimpedance measuring device for measuring the bioimpedance of at least one part of the tissue surrounding the oesophageal electrode probe. The bioimpedance device comprises at least one first and one second electrode, wherein the at least one first electrode (12A) is arranged on a side (14) of the oesophageal electrode probe facing towards the heart and the at least one second electrode (12B) is arranged on a side (16) of the oesophageal electrode probe facing away from the heart. The device (100) comprises the oesophageal electrode probe (10) and a control and/or evaluation device (30), which is configured for receiving a first bioimpedance measurement signal from the at least one first electrode (12A) and a second bioimpedance measurement signal from the at least one second electrode (12B), and comparing same, and generating a control signal on the basis of the comparison. The control signal can be a signal for the open-loop or closed-loop control of a cardiac catheter ablation device and/or a cardiac, circulatory and/or respiratory support device.

Method for controlling a device, in particular, a prosthetic hand or a robotic arm (US20200327705A1)
(2020)
A method for controlling a device, in particular a prosthetic hand or a robotic arm, includes using an operator-mounted camera to detect at least one marker positioned on or in relation to the device. Starting from the detection of the at least one marker, a predefined movement of the operator together with the camera is detected and is used to trigger a corresponding action of the device. The predefined movement of the operator is detected in the form of a line of sight by means of camera tracking. A system for controlling a device, in particular a prosthetic hand or a robotic arm, includes a pair of AR glasses adapted to detect the at least one marker and to detect the predefined movement of the operator.
The invention relates to the field of transporting flat substrates such as silicon substrates. In particular, the invention relates to particularly protective and continuous transport of such substrates. The method according to the invention is used to transport a vertically aligned flat substrate (1) comprising two flat sides in a transport direction inside a transport channel (2) that is at least partially filled with a liquid medium (F), wherein said liquid medium (F) flows against at least one of the flat sides of the substrate (1) and has a supporting component, which lifts the sum of the weight and buoyancy force of the substrate (1), and an advancing component, which is directed in the transport direction, so that the substrate (1) is supported and transported without mechanical aids. The device according to the invention comprises a transport channel (2) for accommodating a liquid medium (F) and a substrate (1) to be guided in vertical alignment within said medium (F), wherein the transport channel (2) has inflow openings (5) in the walls (3, 4).
The invention relates to a multi railed track vehicle, designed with a conducting connection of pairs of rails with a connection resistance reducing agent for reducing the connection resistance to the rail. According to the invention, the connection resistance reducing agent is designed to generate arcs between at least one rail and the track vehicle.
The invention concerns a method for spectrum monitoring a given frequency band, in which the spectral power density (S(f)) within the given frequency band is determined for all noise and signal components in the frequency band and, in order to detect the presence of one or more signals within the given frequency band, it is evaluated whether the spectral power density (S(f)) exceeds a threshold value (&lgr;). According to the invention, the threshold value (&lgr;) is calculated in accordance with an estimation of a distribution density (hR(S)) for the noise component of the spectral power density (S(f)) within the given frequency band and in accordance with a predefined value for the false-alarm probability (Pfa).
The invention relates to a method and to a device for determining the state of charge (SOC) of a rechargeable battery (106) of a specified battery type or a parameter physically related thereto, in particular a remaining charge amount Q contained in the battery, the method operating by means of a voltage-controlled battery model (102), which is parameterized for the battery (106) in question or a corresponding battery type. It is merely necessary to measure the battery voltage Umess and to provide said battery voltage to the battery model (102) as an input variable. The invention further relates to a method and to a device for determining the state of health (SOH) of a battery (102), wherein the battery model (102) also used to determine the SOC provides a modeled battery current Imod. Modeled charge amounts during charging and discharging phases of the battery (106) can be determined from said modeled battery current and can be compared with measured charge amounts, which are determined from the measured battery current Imess. Because the battery model (102) does not age, the SOH of the battery can thereby be determined.
