Abstract: The disclosed system may include a detachable capsule that includes a capsule-side capacitive plate. The system may also include a receiving antenna electrically connected to an antenna-side capacitive plate, and a capacitive sensor electrically connected to the capsule-side capacitive plate. The two plates may be coupled to each other and may transmit RF signals between them. The capacitive sensor may be configured to detect an amount of capacitance between the two capacitive plates. The system may also include an antenna matching tuner electrically connected to the capacitive sensor and to an antenna feed. Then, upon receiving capacitance measurements from the capacitive sensor, the antenna matching tuner may alter various parameters of the antenna feed including impedance matching parameters. Various other apparatuses and mobile wearable devices are also disclosed.

Abstract: The present disclosure provides a direct current (DC) transformer error detection apparatus for a pulsating harmonic signal, including a DC and pulsating harmonic current output module and an external detected input module, where the DC and pulsating harmonic current output module outputs a DC and a DC superimposed pulsating harmonic current to an internal sampling circuit and a self-calibrated standard resistor array; and the internal sampling circuit converts the input DC and the input DC superimposed pulsating harmonic current into a voltage signal, and sends the voltage signal to an analog-to-digital (AD) sampling and measurement component through a front-end conditioning circuit and a detected input channel. The DC transformer error detection apparatus can complete self-calibration for measurement of the DC and the pulsating harmonic signal on a test site.

Abstract: This invention discloses a collapsible container, comprising a base and two pairs of opposite side walls. The side walls are provided with one or more movable portions extending from the bottom of the side walls. The base is provided with one or more opening pockets, wherein the side walls are disposed in the corresponding opening pockets on the base via the movable portions. A hinge device is provided between the movable portions and the opening pockets. The hinge device comprises: hinge holes provided in the movable portions of the side walls; a guiding device provided in the opening pockets of the base; and a connecter provided with hinge pins and a sliding device to be engaged with the guiding device. The sliding device of the connecter is movable up and down in vertical direction along the guiding device in the opening pockets. The hinge pins are disposed in the hinge holes and are rotable around the hinge pins.

Abstract: The present invention discloses a cover device used to cover the built-in valve mounting channel port of IBC and a container. The IBC comprises a side plate, a base and a channel located in the base and used to receive the built-in valve. The cover device comprises a cover and structures or components used to detachably connect the cover to the side plate over the channel. The cover can be installed on the base at the position adjacent to the side plate, and can be rotated around a rotational axis of the cover itself, so as to open or cover the channel port. The cover is further provided with a lock hole, and the base is provided with a locking slot, so that the cover can be locked to the base by a disposable lock. The cover device of the present invention has a simple structure and is easy to operate. Further, it can well achieve the effect of dust-proof and/or thief-evident.
