Abstract: A concrete with oil shale waste residue as aggregates and a preparation method thereof are provided by the present disclosure, belonging to the technical field of concrete. Oil shale waste residue is used to partially or completely replace the fine aggregates and coarse aggregates in the concrete, where the oil shale waste residue is deoiled oil shale waste residue. The oil shale waste residue is subjected to oil removal treatment and applied to the preparation of concrete.

Abstract: An illustrative example elevator door interlock includes a base, a plurality of interlock bumpers supported on the base, and a latch supported on the base for movement relative to the base between a door locking position and a released position. The plurality of interlock bumpers are supported on the base with a gap between the plurality of interlock bumpers. Each of the interlock bumpers includes a contact surface configured to contact at least one vane supported on an elevator car door. Each of the interlock bumpers remains rotationally fixed relative to the base. The latch includes a latch bumper that is situated relative to the gap such that the at least one vane contacts the latch bumper and urges the latch into the released position when the at least one vane is at least partially in the gap.

Abstract: A wireless receiver includes a guided user interface to enable and assist users to optimally select groups and frequencies for wireless communication with wireless transmitters is provided. The wireless receiver may automatically detect the connectedness and parameters of wireless receivers in order to adaptively display and select setup options and messages. The guided user interface may improve user satisfaction and reduce the configuration time of the wireless receivers.

Abstract: The present invention provides a dual conversion gain image sensor comprising: a pixel circuit, through which pixel power supply voltage noise is transferred to a bit line; a power supply noise cancellation circuit with an input to which the pixel power supply voltage is applied, the power supply noise cancellation circuit mimicly producing a first transfer function with the aid of a low conversion gain path, the power supply noise cancellation circuit mimicly producing a second transfer function with the aid of a high conversion gain path; and a comparator. According to the present invention, the low and high conversion gain paths are two independent power supply noise cancellation paths that result in different transfer functions capable of tracking the variation of the pixel power supply voltage in low and high conversion gain modes.

Abstract: A first forwarding device in a software defined network (SDN) detects disconnection of an out-band connection between the first forwarding device and a controller, sends an SDN packet to the controller via an out-band connection of a second forwarding device adjacent to the first forwarding device, and receives a response packet sent by the controller via the second forwarding device.
