  • Patent number: 7676903
    Abstract: /The present invention provides a method of use for a monolithic device utilizing cascaded, switchable slow-wave CPW sections that are integrated along the length of a planar transmission line. The purpose of the switchable slow-wave CPW sections element is to enable control of the propagation constant along the transmission line while maintaining a quasi-constant characteristic impedance. The method can be used to produce true time delay phase shifting components in which large amounts of time delay can be achieved without significant variation in the effective characteristic impedance of the transmission line, and thus also the input/output return loss of the component. Additionally, for a particular value of return loss, greater time delay per unit length can be achieved in comparison to tunable capacitance-only delay components.

  • Patent number: 7669318
    Abstract: A high-speed process includes removing chips or interposers from a carrier web having a first pitch and transferring the chips or interposers to electrical components, such as RFID antenna structures, on a moving web having a second pitch. According to one method, a transfer drum transfers chips or interposers to a moving web of electrical components by picking a chip when the transfer drum is stationary, and transferring the chip to the moving web when the transfer drum is rotating such that a tangential velocity of the transfer drum is substantially equal to the linear velocity of the moving web. According to another method, a primary drum removes chips or interposers from a carrier web having a first pitch, and transfers the chips or interposers to a variably rotating secondary drum which then places the chips or interposers onto an electrical component on a moving web having a second pitch.

  • Patent number: 7665202
    Abstract: The present invention relates to a process for producing a block of low-frequency piezoelectric composite material having rows of superposed ceramic posts embedded in a dielectric. This process includes the production of the block of composite material from two superposed identical half-blocks, produced by cutting into a single pre-machined piezoelectric ceramic block. According to the invention, the block of ceramic material thus constituted is then machined so as to form a structure comprising rows of aligned posts, each post being formed from two elementary posts facing each other in strict alignment. The ceramic structure thus produced is then integrated into an appropriate dielectric matrix. The block thus produced is intended to be used for manufacturing acoustic transducers from composite materials. The invention relates in particular to the field of sonar detectors designed to detect objects located at a relatively short distance from the detector.
