摘要： Methods and circuital arrangements for turning OFF branches of a multi-branch cascode amplifier are presented. First and second switching arrangements coupled to a branch allow turning OFF the branch while protecting transistors of the branch from a supply voltage that may be greater than a tolerable voltage of the transistors. The first switching arrangement includes a transistor-based switch that is in series connection with the transistors of the branch. The first switching arrangement drops the supply voltage during the OFF state of the branch and provides a conduction path for a current through the branch during the ON state of the branch. A resistor and a shunting switch are coupled to a gate of the transistor-based switch to reduce parasitic coupling effects of the transistor-based switch upon an RF signal coupled to the branch during the ON state and OFF state of the branch.

摘要： A bicycle gearshift including a first body associated with a bicycle frame, a second body connected to, and moveable relative to, the first body, a rocker arm rotatably connected to the second body at a rotation axis, and a shaft extending coaxially to this axis and fixedly associated with the rocker arm. A unidirectional rotation device is arranged between the shaft and second body to allow rotation of the shaft relative to the second body only in a first rotation direction. An elastic element is associated with the second body and the rocker arm to push the rocker arm in rotation about the axis in the first rotation direction. A damping device is arranged between the shaft and unidirectional rotation device to generate a friction force when the rocker arm is rotated in a second, opposite rotation direction, and has a friction surface in contact with the unidirectional rotation device.

摘要： Circuits and methods for transmitting high-voltage (HV) static and/or switching signals via a high-voltage (HV) transmission gate controllable via low-voltage (LV) logic are presented. The HV gate includes a biasing circuit for generating a biasing voltage to gates of two series-connected HV transistors. According to one aspect, the biasing voltage is generated through a pull-up device coupled to a HV supply having a voltage level higher than a high voltage of a signal to be transmitted. According to another aspect, the biasing voltage is generated through a LV supply coupled to a diode, and a capacitor coupled between the gates and the sources of the HV transistors. When the gate is activated, the combination of the LV supply coupled to the diode and the capacitor generates a biasing voltage based on a sum of a voltage of the LV supply and an instantaneous voltage level of the signal being transmitted.

摘要： A carcass sleeve is situated in a radially external position with respect to a toroidal forming drum, arranged in a first radially contracted operative condition. The carcass sleeve is shaped according to a toroidal configuration while the forming drum is positioned inside the carcass sleeve. During shaping of the carcass sleeve, the forming drum is radially expanded up to a second radially expanded operative condition. Upon completed shaping, the carcass sleeve is coupled to the forming drum in the second operative condition. The forming drum, coupled to the shaped carcass sleeve, is arranged in proximity to at least one device for building at least one belt layer at a radially external position relative to the shaped carcass sleeve.

摘要： Various methods and circuital arrangements for biasing gates of stacked transistor amplifier that includes two series connected transistor stacks of different polarities are presented, where the amplifier is configured to operate according to different modes of operation. Such circuital arrangements operate in a closed loop with a feedback error voltage that is based on a sensed voltage at a common node of the two series connected transistor stacks. According to one aspect, gate biasing voltages to input transistors of each of the two series connected stacks are adjusted by respective current mirrors that are controlled based on the feedback error voltage. According to another aspect, other gate biasing voltages are generated by maintaining a fixed gate biasing voltage between any two consecutive gate basing voltages.

摘要： Systems and methods for material processing using wafer scale waves of precisely controlled electrons in a DC plasma is presented. The anode and cathode of a DC plasma chamber are respectively connected to an adjustable DC voltage source and a DC current source. The anode potential is adjusted to shift a surface floating potential of a stage in a positive column of the DC plasma to a reference ground potential of the DC voltage/current sources. A conductive plate in a same region of the positive column opposite the stage is used to measure the surface floating potential of the stage. A signal generator referenced to the ground potential is capacitively coupled to the stage to control a surface potential at the stage for provision of kinetic energy to free electrons in the DC plasma.

摘要： Electrically tunable metasurfaces including an array of subwavelength metasurface unit elements are presented. The unit elements include a stacked metal-insulator-metal structure within which an active phase change layer is included. A purely insulator, metal, or coexisting metal-insulator phase of the active layer can be electrically controlled to tune an amplitude and phase response of the metasurfaces. In combination with the subwavelengths dimensions of the unit elements, the phase and amplitude response can be controlled in a range from optical wavelengths to millimeter wavelength of incident light. Electrical control of the unit elements can be provided via resistive heating produced by flow of current though a top metal layer of the unit elements. Alternatively, electrical control of the unit elements can be provided via electrical field effect produced by applying a voltage differential between the top and bottom metal layers of the unit elements.

摘要： A process for applying noise-reducing elements to a tyre for vehicle wheels. A plurality of noise-reducing elements are arranged on a feeding belt movable along a predetermined feeding direction. The noise-reducing elements are subsequently aligned along the feeding direction and brought into mutual contact, to then be transferred onto a service plane arranged downstream of the feeding belt along the feeding direction and having, on an upper surface thereof, a continuous film which supports a layer of adhesive material. The layer of adhesive material is applied onto a lower surface of each of the noise-reducing elements taking it from the continuous film. The noise-reducing elements are then transferred one by one onto a conveyor belt arranged downstream of the service plane along the feeding direction. The noise-reducing elements are finally positioned one by one on a radially inner surface of a tyre.
