    摘要： A wireless power system includes a wireless power transmitting device such as a wireless charging mat for charging devices such as a cellular telephone and an earbuds battery case. The earbuds battery case receives earbuds and charges the earbuds from a battery. The wireless charging mat supports bidirectional in-band communications between the cellular telephone and the earbuds battery case. The earbuds battery case provides the cellular telephone with information on the battery charge level associated with the battery in the earbuds battery case and a battery charge level associated with each earbud in the earbuds battery case. The cellular telephone receives battery charge level information through the wireless charging mat and displays corresponding indicators. The earbuds battery case has a visual output device such as a light-emitting diode that is illuminated to indicate that the earbuds battery case is being charged.

    摘要： Host content is received from a host device coupled to an external display device. The host content is displayed on the external display device when an orientation state of the external display device is a first orientation state. Change of the orientation state from the first orientation state to a second orientation state is detected, e.g., with a sensor. Orientation data corresponding to the second orientation state is transmitted to the host device. Host content, which has been transformed by a rendering pipeline configured at the host device based on the transmitted orientation data corresponding to the second orientation state, is received from the host device. The transformed host content is displayed on the external display device in response to the orientation state of the display device being changed to the second orientation state. In other embodiments, the display may be updated continuously during the orientation change.

    摘要： Devices and methods for controlling brightness of a display backlight are provided. A display backlight controller may control the brightness of the display backlight by changing a duty cycle of a PWM signal that drives the LED current. However, because of LED efficacy and response time, the final output brightness (NITS) may not be linear between 0% to 100%. The disclosed methods may be used to correct the brightness using a predetermined correction factor. Further, the minimum and maximum duty cycle of the output dimming duty cycle may be limited or corrected. In one example, a backlight controller receives an input duty cycle and determines a product of the input duty cycle and a maximum duty cycle to produce a reduced duty cycle. Moreover, the backlight driver may determine a corrected duty cycle using the correction factor. The final output duty cycle and LED current may then be determined.
