Abstract: The present disclosure discloses a heated throw. The heated throw includes rectangular shawl body with an electric heating layer laid inside. A connector which is electrically connected to the electric heating layer and a silicone key is fixed to a position, relatively close to a corner, on the shawl body. The silicone key is sewn on the shawl body to facilitate an operation and avoid a solution of directly operating by a controller, so that the heated throw is more convenient and fast to use. The electric heating layer and the silicone key are electrically connected to the connector. The connector is connected to a plug through the controller. The controller is used for controlling heating output of the electric heating layer, and exchanging heated throw state information and user control information with the silicone key through the connector.

Abstract: The present disclosure discloses an electric heating blanket. The electric heating blanket includes a rectangular electric heating blanket body with an electric heating layer laid inside. A connector which is electrically connected to the electric heating layer and a silicon key is fixed to the central position on the electric heating blanket body. The silicon key is sewn on the electric heating blanket body to facilitate operation and avoid a solution of directly operating by a controller, so that the electric heating blanket is more convenient and fast to use. The electric heating layer and the silicon key are electrically connected to the connector. The connector is connected to a plug through the controller. The controller is used for controlling heating output of the electric heating layer, and exchanging electric heating blanket state information and user control information with the silicon key through the connector.

Abstract: The present application relates to the technical field of household electric appliances, in particular to a novel electric heating covering device, which includes a main controller integrated in a male connector and configured to realize real-time temperature control; an auxiliary controller provided with a built-in control circuit with an MCU and configured to acquire user control information; an auxiliary control power supply and communication line configured to connect the main controller and the auxiliary controller, wherein the main controller supplies power to the auxiliary controller through the auxiliary control power supply and communication line to realize two-way communication; a heating body provided with a heating wire and configured to convert electric energy into heat energy. Therefore, the present application only needs one power line for connection with the mains supply, and completely realizes real-time temperature control.

Abstract: An improved promoter and a use thereof. An improvement is to mutate a nucleic acid sequence between ?35 region and ?10 region in a promoter region into recognition sites for an endonuclease. The improvement can overcome the problem that a strong promoter in a vector based on blue-white screening initiates the transcription or translation of foreign genes and a transcription or translation product might be toxic to a host and cannot be cloned, avoid the deficiency that frameshift mutation of a gene due to a lack of 1-2 bp of the vector at digestion sites results in false positive clones, and eliminate a false negative phenomenon that a plate is rich in blue spots due to a small fragment of foreign DNA and a reading frame of the gene which is unchanged by inserting the foreign DNA.

Abstract: An improved promoter and a use thereof. An improvement is to mutate a nucleic acid sequence between ?35 region and ?10 region in a promoter region into recognition sites for an endonuclease. The improvement is used for overcoming the problem that a transcription or translation product of foreign genes under a strong promoter might be toxic to a host and cannot be cloned and avoiding the phenomena of false positives and false negatives during blue-white screening.
