A modular electronic device system includes an electronic device and a cover for the device that allows the device to be mechanically and electrically mounted to a stand or device adapter on the rear side of the cover. The cover or device adapter can be connectable to modularly attachable and removable accessory devices and can provide electrical ports for powering and operating the accessory devices. While mounted to a stand, power and data communications can be provided to the electronic device, cover, and accessory devices from the stand or an external source. The modular components of the system can be interchangeable to allow the system to be adapted to many different settings and use cases based on the types of components included as the accessory devices and based on the number of accessory devices used.

In some examples, a power adapter comprises a first connector having multiple power setting keys, the first connector to couple to a first device; a second connector to couple to a second device; and a processor coupled to the first connector and the second connector, the processor to determine if the second device is configured to supply power in accordance with a power setting of the first device.

A powering patch panel system includes a patch panel device coupled to a power source, and including a first port that is coupled to a networking device via a first cable and a second port that is coupled to the powered device via a second cable. The patch panel device receives data that is directed to the powered device from the networking device through the first port and via the first cable, and receives power from the power source. The patch panel device then transmits both the data and a subset of the power through the second port and via the second cable to the powered device. The first port may be provided by optical-fiber-based port and the first cable may be provided by an optical-fiber-based cable, while the second port may be provided by a hybrid conductive-material/optical-fiber-based port and the second cable may be provided by a hybrid conductive-material/optical-fiber-based cable.

An image processing apparatus includes a connection unit, a first power supply unit, a second power supply unit, and a control device. The connection unit is connected to an electronic apparatus including a controlled device and a communication relay unit. The first power supply unit can supply power to the controlled device. The second power supply unit can supply power to the communication relay unit. The control device is capable of switching a power supply state by the first power supply unit and the second power supply unit between at least a first stop state in which power supply by the first power supply unit is continued and power supply by the second power supply unit is stopped and a second stop state in which power supply by the first power supply unit and the second power supply unit is stopped.

According to an example embodiment, an electronic device includes: a universal serial bus (USB) power delivery integrated circuit (PDIC) configured to determine whether a first pin of a USB port of the electronic device is connected to a power delivery (PD) source; a charging circuitry configured to charge a battery of the electronic device with power supplied from the PD source through a second pin of the USB port; a memory configured to store computer-executable instructions; and a processor configured to execute the instructions by accessing the memory. When the USB PDIC determines that the first pin and the PD source are connected, the instructions may cause the processor to control a voltage of the second pin to be less than a threshold voltage while maintaining communication between the USB PDIC and the PD source through the first pin based on a state of the electronic device. In addition, various example embodiments may be possible.

A power management device and a consumer electronic product are provided. The power management device is for the consumer electronic product. The power management device includes a memory and a controller. The memory stores a power information of a load of the consumer electronic product. An input end of the first voltage regulator is coupled to a power pin of an upstream USB connector, and an output end of the first voltage regulator is coupled to a power end of the load. When USB device is connected to a downstream USB connector of the consumer electronic product, the controller obtains a power demand from the USB device, the controller determines whether to change a power mode of the upstream USB connector according to the power information and the power demand, and the controller controls the second voltage regulator according to the power mode to supply power to the USB device.

An electrical transmitter (100) is provided that comprises an ethernet connection (118) and a power source. Electronics (112) are configured to receive the ethernet connection (118) and the power source. The electronics (112) comprise logic operable to detect the power source and accept power from either the ethernet connection (118) or a dedicated power connection (116). A remappable power connection terminal (114) with the electronics (112) is operable to accept power when the dedicated power connection (116) is detected, and operable to accept a non-power connection when power from the ethernet connection (118) is detected.
