Abstract: Example implementations relate to transceiver modification based on data sizes and signal strengths. In some examples, an electronic device can include a transceiver, the transceiver including a first transceiver circuit including a first transmitter and a first receiver and a second transceiver circuit including a second transmitter and a second receiver, and a processor, where the processor is to determine a data size of data to be transmitted to a host device, determine a signal strength of the first receiver and a signal strength of the second receiver with a host device, and modify the transceiver based on the data size and the signal strength of the first receiver and the signal strength of the second receiver.

Abstract: In an example, an electronic device includes a first antenna and a second antenna. The electronic device may further include a power modulator to determine a simultaneous operation of the first antenna and the second antenna. The power modulator may monitor a first signal parameter of the first antenna and a second signal parameter of the second antenna. Upon monitoring signal parameters of respective antenna, the power modulator may dynamically regulate a first transmission power of the first antenna and a second transmission power of the second antenna based on the first signal parameter, the second signal parameter, and a threshold transmission value.

Abstract: An electric sofa power supply system includes a power supply unit, a USB female connector having a trigger signal. When the trigger signal pin of the USB female connector is electrically connected with a mating USB male connector of an external electric device, the control unit controls the power supply unit to provide power to the USB female connector. When the USB female connector is electrically disconnected from the mating USB male connector of the external electric device, the control unit cuts off the power supply of the power supply unit to the USB female connector, achieving zero power consumption, energy saving and environmental protection, and enhancing the safety of using the power supply system. The electric sofa power supply system does not need to add a switch to the electric sofa to control the power supply of the USB female connector, which greatly increases the aesthetics and practicability.

Abstract: The present invention provides a method and apparatus for forming an image. A controller manages a charger and a developing bias voltage to increase an absolute value of the charging voltage to an image-bearing member and an absolute value of a developing bias voltage to a developer-bearing member to predetermined values in a plurality of steps. The controller controls the developing bias voltage applied to the developer-bearing member; wherein the following relation holds in each of the plurality of steps: |VD|>|Vi|, where VD represents a developing bias voltage applied to the developer-bearing member and Vi represents a charged potential of the image-bearing member. This invention is especially useful for mono-component development using DC voltage as a development driving mechanism.

Abstract: A developing method improves the printed image quality of an image-forming device by removing surplus charge potential to make the surface potential of a photoreceptor charged during first and second charging steps be the same for next developing, or by inputting different voltages to the developing units. An image-forming device is also disclosed.

Abstract: A structural steel seismic-resistant beam-to-column connection is provided with a pair of rib plates installed symmetrically above and below the connection. The rib plates are perpendicularly to an upper and a lower beam flange and disposed at positions corresponding to the center of the beam web. The rib has a variable cross section at its front end and a relatively lower lengthened section at its rear end. Through the use of the rib plate, the stress concentration at those fan type weld access holes of the beam web as well as the junction of the full penetration weld between the beam flange and column flange can be alleviated, and the plastic hinge can be limited to the beam at a specified portion and can develop excellent plastic rotation capacity in the case of a severe earthquake.
