    摘要: An interdigitated RF filter. The interdigitated RF filter includes input fingers connected to an input node and output fingers connected to an output node where at least one input finger is connected the output node or at least one output finger is connected to the input node. The described interdigitated RF filter can be implemented in various configurations such as series, shunt, ladder or a combination thereof.

    摘要: Apparatus for applying noise reducing elements to tyres for vehicle wheels. The apparatus includes a loading station of stacks of noise reducing elements, an extraction station of noise reducing elements from each stack placed downstream of the loading station, and a conveyor placed downstream of the extraction station and extending along a predefined path. The conveyor is configured for supporting and advancing in a row the noise reducing elements extracted from the stacks which are then applied to a radially inner surface of the tyres. The extraction of each of the noise reducing elements contemplates: retaining a first noise reducing element placed at the base of a stack; raising the remaining noise reducing elements of the stack from the first noise reducing element; moving away the first noise reducing element according to a set path; and lowering the remaining noise reducing elements of the stack.

    摘要: A carcass sleeve including a carcass ply and a pair of annular anchoring structures is fitted around a toroidal forming drum arranged in a first radially contracted operational condition. The carcass sleeve is toroidally shaped against a radially inner surface of an annular contrast element. The forming drum is positioned inside the carcass sleeve and is concurrently expanded towards a second operational condition. Upon reaching the second operational condition, the toroidally shaped carcass sleeve is coupled to the forming drum. The forming drum, coupled to the carcass sleeve, is adapted to be transferred in proximity of an application device of additional components externally to the carcass sleeve.

    摘要: RF transistors manufactured using a bulk CMOS process exhibit non-linear drain-body and source-body capacitances which degrade the linearity performance of the RF circuits implementing such transistors. The disclosed methods and devices address this issue and provide solutions based on implementing two or more bias voltages in accordance with the states of the transistors. Various exemplary RF circuits benefiting from the described methods and devices are also presented.

    摘要: A wearable computing contact tracing, medical tracking and passport device has a main body with a QR code, at least one indicator light, a location tracker, and a processor. The indicator light provides a first visual indication, such as a red light, of when the user has been exposed to a pandemic disease and a second visual indication, such as a green light, of when the user is immune to the pandemic disease.

    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: A graphics adaptation method for printable ceramic supports. Images are printed on sample ceramic supports starting from an original image file. A sample printed image is acquired. Sample points representative of the sample image are selected. Original points present in the original image file are also selected. A point-based matching is sought between the sample points and the original points, on the basis of which the original image file is modified and an adapted image file is determined, thus adapting the graphics of the original image file to the graphics of the sample image. A graphics adaptation system based on the method is also described.
