The present invention relates to methods and systems for minimizing alien crosstalk between connectors. Specifically, the methods and systems relate to isolation and compensation techniques for minimizing alien crosstalk between connectors for use with high-speed data cabling. A frame can be configured to receive a number of connectors. Shield structures may be positioned to isolate at least a subset of the connectors from one another. The connectors can be positioned to move at least a subset of the connectors away from alignment with a common plane. A signal compensator may be configured to adjust a data signal to compensate for alien crosstalk. The connectors are configured to efficiently and accurately propagate high-speed data signals by, among other functions, minimizing alien crosstalk.

Electronic devices and accessory devices for electronic devices are described. In some instances, an accessory device includes a keyboard and a cover rotatable with respect to the keyboard. In some instances, an accessory device includes a back panel and a foldable cover rotatable with respect to the back panel. These accessory devices may include several magnetic elements designed to magnetically couple with, and retain, an electronic device without any additional mechanical or other interlocking devices. In this regard, the magnetic elements in the accessory devices provide an external magnetic field sufficiently strong enough to retain the electronic device, and can counter gravitational forces and/or the weight of the electronic device. However, some accessory devices include additional magnetic elements that provide an external magnetic field that repels magnetic elements in the electronic device. Also, the magnetic elements may also be used to hold different sections of the accessory device together.

The present invention discloses a sofa USB socket including: a USB female socket including a tongue core, wherein the tongue core includes 5 pins, and the fifth pin is an ID pin; and a USB circuit including a power circuit, a filter circuit, a control chip and a buck chopper circuit, wherein the buck chopper circuit includes a transistor, and the ID pin is electrically connected with the transistor. When an external USB male plug is inserted into the USB female socket, the power circuit supplies power to the USB female socket; when the USB female socket is in an unloaded state, the fifth pin is suspended, the control chip enters a sleep state, and the USB female socket has no output voltage, which greatly reduces the no-load energy consumption, thereby being beneficial to extending the endurance time and the service life of a power supply battery.

A wall mounted power supply device includes a housing, a transformer unit, including an input winding and at least one output winding; and at least one output circuit corresponding to the at least one output winding. Each output circuit includes: a rectifier unit, coupled to the output winding, to rectify a current of the output winding to generate a DC voltage signal; a DC-to-DC converter, to generate an output signal at an output connector based on the DC voltage signal. The transformer unit and the rectifier unit are sealed within the housing by a thermal adhesive to form a sealed integral unit with the housing. The device has a simple circuit design, is low cost and easy to install, and reliable.

A resettable switching apparatus, useful in a GFCI receptacle, has an auto-monitoring circuit for automatically testing various functions and structures of the device. The auto-monitoring circuit initiates an auto-monitoring routine which, among other things, establishes a test fault situation on either the positive or negative half-wave of the power cycle and determines whether the detection mechanisms within the device appropriately detect the test fault and whether the device would trip in the event of an actual fault. Additional functionality of the auto-monitoring circuit permits automatic verification that the device is properly wired, that is, not miswired, and determines whether the device has reached the end of its useful life.
