Electrical Measurement Assembly Suitable for Portable Work Platforms
A portable measurement assembly suitable for a work platform is disclosed. The assembly includes a housing that supports and protects a measurement device. The housing forms a first passage that receives a line-in electrical supply and a second passage that provides a line-out to a load. The measurement device is coupled to the line-in electrical supply. The portable measurement assembly is safe, convenient and enables an operator to determine an electrical condition at a work platform when the supply circuit is under load.
Identification circuit and method for power-line carrier signal, and integrated circuit chip
The present application discloses an identification circuit for a power-line carrier signal. During signal transmission on a power line, the amplitude change and duration of a voltage signal on the power line are identified and then decoded into corresponding data, so as to reduce dependency on a power supply voltage during signal identification, and prevent the signal identification rate from decreasing as a result of an increase in the transmission distance, thereby reducing requirements for a system power supply.
DIGITAL VOLTAGE SAMPLING
According to some examples, systems and methods are provided for voltage sampling using one or more analog-to-digital converters (ADCs) to sense divided portions of a sampled voltage (e.g., of an output signal), using the one or more analog-to-digital converters to provide a plurality of digital values representative of those divided portions, and combining the plurality of digital values to produce a total digital value representative of the sampled voltage. Such systems and methods can achieve a high resolution for the total digital value while permitting use of ADCs that have a resolution lower than would otherwise be required to achieve the high resolution.
METHODS AND DEVICES FOR SAMPLE CHARACTERIZATION
Provided herein are methods and devices for the detection, quantification, and/or monitoring of characteristics in samples. The disclosed methods and devices can be used, for example, to identify the presence and location of atrial fibrillation indicators with high spatial resolution. The disclosed methods and devices can even be used to identify the presence and location of atrial fibrillation indicators using non-simultaneously collected data.
Diagnostic device for voltage sensors
In a diagnostic device, a determiner determines whether a rotational speed of an AC motor is within a low rotational-speed range in which its rotational speed is approximately zero. An input-voltage estimate calculator calculates, as an input-voltage estimate, an estimate of an input voltage to an inverter when it is determined that the rotational speed of the AC motor is within the low rotational-speed range. A malfunction determiner performs a diagnostic task. The diagnostic task calculates an absolute value of a difference between an input-voltage measurement value measured by an input voltage sensor and the input-voltage estimate. The diagnostic task determines whether the absolute value of the difference is higher than a predetermined voltage threshold. The diagnostic task determines that there is a malfunction in the input voltage sensor upon determining that the absolute value of the difference is higher than the predetermined voltage threshold.
Electrode Lead, Implant, and Method for Identifying an Electrode Lead
An implant including a hermetically tightly sealed housing, wherein a control unit is arranged in the housing, and including a header, which is secured to the housing and includes at least one socket for connection to a plug of an electrode lead, and includes a communication antenna, which is electrically connected to the control unit. To achieve a reliable identification of the electrode lead with a low energy expenditure, the header has, in the region of the at least one socket, at least one electromagnetic transmission element electrically connected to a contact element which is provided on the inner wall of the at least one socket or to the ground of the implant and to the control unit, wherein the electromagnetic transmission element is electromagnetically or inductively coupled to the communication antenna. A corresponding electrode lead and a corresponding method for identifying an electrode lead are also contemplated.
Electrode Lead, Implant, and Method for Identifying an Electrode Lead
An electrode lead having a plug for connecting to an implant having a control device and a communication antenna connected to the control device, and having at least one electrical conductor and one insulating tube insulating the at least one electrical conductor. To simply/reliably transmit information of the electrode lead to the implant (with a low expenditure of energy), a hermetically sealed passive RFID label is embedded: in the insulating tube, and/or in the plug, or in an insulating body of a separate additional part connectable to the insulating tube or the plug. The RFID label has an RFID chip and an inlay antenna connected in an electrically conducting manner to the RFID chip. The inlay antenna is electromagnetically coupled to the at least one electrical conductor and the communication antenna. A corresponding method for identifying an electrode lead and a corresponding implant are also contemplated.

METHOD FOR OPTIMISING A WETTING CURRENT AND ADAPTED DEVICE FOR MONITORING SENSORS WITH CONTACT SWITCHES
Disclosed is a method for optimizing a wetting current, for a device for monitoring sensors with contact switches including a current source and at least two switch/resistor assemblies (CT1/R1, CT2/R2) in parallel, including the following steps: the current source (A) supplies the circuit with a nominal current; if a voltage (Vm) measured across the terminals of the switch/resistor assemblies is greater than a threshold voltage (Vs), the threshold voltage being lower than the supply voltage of the current source and than the saturation voltage of the analog-to-digital converter (CAN), then the current source is stopped and a unit for discharging the circuit are implemented; and the current source supplies the circuit again with a supply current (Iwet_c) equal to the nominal current reduced by a predetermined increment. These two last steps are repeated until the measured voltage is lower than the threshold voltage.
CORRECTION METHOD AND RELATED ASSEMBLY
Disclosed are a correction method and a related assembly. According to a solution, loading is performed on an electronic load, and during each loading, a digital multimeter collects the output voltage of a VR inverter; after loading is ended, it is determined whether the average voltage value of the output voltage collected by the digital multimeter is within a preset voltage range, so as to determine whether the VR inverter stably performs output; and when the average voltage value is not within the preset voltage range, it can be determined that the output of the VR inverter is unstable, and it is needed to correct the VR inverter, i.e., the correction of the VR inverter is realized by adjusting the impedance of a digital potentiometer arranged between the output end and the feedback end of the VR inverter.
