摘要： An amplifier stage or circuit for providing cross-point adjustment. The circuit may include a first input node configured to receive a first data signal and a second input node configured to receive a second data signal that is complementary of the first data signal. The circuit also includes a programmable first stage having a first node coupled to the first input node and a second node coupled to the second input node that is configured to adjust an amount of current provided to the first and second data signals to create a signal offset. The circuit further includes a second stage having a first node coupled to a third node of the programmable first stage and a second node coupled to a fourth node of the programmable first stage configured to provide the signal offset at a third and fourth node of the second stage to adjust the cross-point of the first and second signals.

摘要： A basketball that uses compression or decompression of piezo elements to produce current that charges a rechargeable battery in the basketball. The current is generated by the piezo elements that are placed between an inner shell and an outer shell of the basketball so that the bouncing of the basketball creates current to charge the battery. The charged battery can be coupled to an electronic device (e.g., smartphone) to charge the electronic device.

摘要： The invention concerns an electrolyzer power supply, especially for use in the industrial production of hydrogen. It is constituted by four sub-assemblies placed side-by-side in a filter-press type structure. These sub-assemblies each comprise electrodes coupled two by two, electrolytic compartments being defined between two groups of electrodes. One group of these electrodes, preferably half of them being made of a metal that has a rectifying effect on AC current, and preferably being aluminum, aluminum-zinc alloys, niobium or tantalum. The counter-electrodes are adapted to evolve oxygen. They are preferably iron, nickel or carbon. A generator providing an alternating current is connected between the end electrodes and between the second and third sub-assemblies. DC is taken from between the first and second and from between the third and fourth sub-assemblies.

摘要： A power supply device for converting an AC power input into a DC power output comprises a rectifier module connected to the AC power input for producing rectified power; a final stage DC-DC converter for producing the DC power output; and one or more smoothing stages provided between the rectifier module and the final stage DC-DC converter to smooth the rectified power. There is an initial DC-DC converter module is provided between the rectifier and one of the smoothing stages to lower the voltage range of the output signal from the rectifier. The lowered voltage range of the rectified power is provided directly to the final stage DC-DC converter, without a power storage device storing the lowered voltage range rectified power.
