We propose a new concept millimetre-wave patch antenna that integrates the functions of an and capacitive proximity sensor to detect hand grip state for 5G mobile terminals compensate effect. The proposed has structure proximity-coupled fed as by using capacitance change occurs when user's approaches patch. By observing at centre operating in TM01 mode, it is possible simultaneously perform wit...

There are fewer problems encountered with optical voltage transducers in comparison with their inductive and capacitive counterparts. Although capacitive and inductive transformers are used vastly for the purpose of measurement and protection in the networks, they cause problems such as core saturation and improper transient responses which decrease the accuracy of measurement and eficiency of ...

In this paper, a four-point characterization method is developed for samples that have either capacitive or ohmic contacts. When capacitive contacts are used, capacitive current- and voltage-dividers result in a capacitive scaling factor not present in four-point measurements with only ohmic contacts. From a circuit equivalent of the complete measurement system, one can determine both the measu...

Based on a capacitive angle and angular rate sensor, a sensor measuring the relative angle between two rotating shafts has been developed. Two rotatable electrodes are placed between two sensor plates. The relative angle between the two rotors and the absolute position of the rotor blades are calculated from measurements of the capacitive coupling between different transmitting stator segments ...

Capacitive and inductive crosstalk noises are expected to be more serious in advanced technologies. However, capacitive and inductive crosstalk noises in the future have not been concurrently and sufficiently discussed quantitatively, though capacitive crosstalk noise has been intensively studied solely as a primary factor of interconnect delay variation. This paper quantitatively predicts the ...

Weakly electric fish emit an AC electric field into the water and use thousands of sensors on the skin to detect field perturbations due to surrounding objects. The fish's active electrosensory system allows them to navigate and hunt, using separate neural pathways and receptors for resistive and capacitive perturbations. We have previously developed a sensing method inspired by the weakly elec...

Capacitive input devices are becoming increasingly prevalent in consumer devices. This paper presents the hardware and algorithms for the low cost implementation of a capacitive 2.5D input device. The low cost and low power consumption of the device make it suitable for use in portable devices such as cellular phones. The electrical properties used are such that the preexisting snap dome techno...
