Abstract: A method and a device for producing medium-thickness plates with high thickness precision through a CVC steckel mill. The method includes the following: heating a blank in the heating furnace, and roughly descaling by the descaling machine; enabling the blank to enter the rolling mill, after multi-pass flat rolling, carrying out multi-pass rolling, carrying out linkage rolling of the rolling mill and the coiler furnaces in the rolling process, and enabling the rolling tension to reach a set value; controlling the temperatures of the coiler furnace to a set value in the coiling process; and in the rolling process, starting 30-70% of the original flow of cooling water of the working roll of the rolling mill; and after rolling is finished, finishing the production process through the laminar cooling system and the hot straightening machine respectively.

Abstract: A dual-mode BLE device identifies idle intervals within Bluetooth BR/EDR traffic communications. The identified idle intervals are used by the dual-mode BLE device to concurrently perform various BLE activities. For example, advertising packet transmissions, advertising packet scanning, connection setup, and/or data packet communication may be concurrently performed within identified idle intervals within the Bluetooth BR/EDR traffic communications. Packet transmission timing, advertising interval, scan window, and/or packet size are determined based on the identified idle intervals within the Bluetooth BR/EDR traffic communications. A scan window is adjusted based on timing of expected advertising transmissions and/or advertising interval(s) for saving power. BLE packets and Bluetooth BR/EDR packets may be detected in a single advertising channel. Maximal payload size is set based on the identified idle intervals within Bluetooth BR/EDR traffic communications.

Abstract: A playpen includes a frame member and a fabric enclosure member. The frame member includes a top frame unit and a plurality of leg units that are connected to the top frame unit. Each of the leg units includes a plurality of first fasteners that are spacedly arranged along a longitudinal direction thereof. The fabric enclosure member includes a plurality of second fasteners for engaging respectively the first fasteners for securing the fabric enclosure member to the frame member. The fabric enclosure member cooperates with the leg units and the top frame unit of the frame member to define an inner play space.
