Abstract: An electronic device includes a display screen, a transparent cover plate, and a sensing unit. The transparent cover plate has a first region and a second region. The first region corresponds to the display screen. The second region includes a non-through hole provided at an inner surface of the transparent cover plate. The sensing unit is arranged in the non-through hole.

Abstract: A DC/DC power supply system includes a primary side and a secondary side to generate an output DC voltage from an input DC voltage. The power supply also includes adaptive clamping circuitry that generates an adjustable clamping voltage and/or current to limit a Vds breakdown voltage for switches of the secondary side.

Abstract: An electronic device may have a housing in which a display is mounted. A gasket may be mounted in a groove between the display and housing. The gasket may contain an embedded stiffener. Corner brackets may be installed in the corners of the housing. The housing may have inner and outer concentric ribs. Recesses in the housing may be configured to receive the corner brackets. The recesses may be formed between the inner and outer concentric ribs. Gap filling structures such as a foam layer may be interposed between a rear housing wall and a display backlight unit. Display color variations may be corrected by using a backlight unit having an array of light-emitting diodes of different colors. An electrostatic discharge protection layer may be grounded to a housing using conductive tape. Black edge coatings and adhesive-based structures may block stray light. Camera window regions may be supported using adhesive.

Abstract: The automatic timed-release water-supplying flowerpot includes an inner container supported in an upper portion of the interior space of an outer container. Water-absorbent ropes are inserted through inlet water holes cut through the bottom wall of the inner container to absorb water from the lower portion of the interior space of the outer container and carry it to the soil and plant in the inner container. A water-refilling opening is formed between a recessed portion of the side wall of the inner container and the side wall of the outer container. The flowerpot is provided with a filtering tray or a hinged cover over the water-refilling opening to block stuffs other than water from entering the interior space of the outer container. The inner container is supported in the outer container by a horizontally extended rim or by one or more supporting legs.

Abstract: A plant watering device includes a first body portion, a second body portion having a chamber therein and connected to the bottom of the first body portion, a third body portion set on the top outer wall of the first body portion, and a water supplying tube which is inserted into one side of the third body portion, extending downwards along one side of the first and second body portions to the bottom of the second body portion and upwards along the opposite side of the second and first body portions, and out of the third body portion at the opposite side. Water is provided by the water supplying tube through a hole into the bottom of the chamber and its pressure is regulated using a micropore material block or a water-absorbent rod in the chamber, and a soft water-permeable disc at the bottom of the first body portion.

Abstract: Embodiments of the present application disclose a bandwidth control method and a bandwidth control device. The method includes: obtaining, by a bandwidth control device, an access request of a mobile terminal, where the access request is used to indicate that the mobile terminal requests to access the Internet by using a home gateway of a fixed terminal; obtaining, by the bandwidth control device, a first bandwidth of the fixed terminal, where the first bandwidth is a subscribed bandwidth of the fixed terminal; and adjusting, by the bandwidth control device, a bandwidth allocated to the fixed terminal from the subscribed bandwidth of the fixed terminal to a second bandwidth, where the second bandwidth is greater than the first bandwidth. In the embodiments of the present application, the impact of mobile terminal access on user experience of the fixed terminal can be reduced.
