摘要： A transducer assembly for a proximity sensor which comprises an elongated polymer piezoelectric film (16). The film is supported as an elongated series of arcuate segments which are curved in the same direction and have the same radius of curvature. Electrodes (18) on both sides of the piezoelectric film form opposed pairs, each pair being associated with a respective arcuate segment. The electrodes are utilized for applying a varying electric field across the thickness of the film to cause an ultrasonic acoustic wave to be radiated from the film.

摘要： The frequency response of a component whose output decreases past a first frequency is extended by employing apparatus which provides for a signal source to be coupled to a component transmission line through a coupling impedance of about zero. The transmission line is resonant at a second frequency greater than the first frequency and the characteristic impedance of the transmission line is selected such that the voltage drop at or near direct current across the component is about equal to the voltage drop across the component at the second frequency. The method of operation comprises providing a signal, forming a transmission line which is resonant at the second frequency and coupling the transmission line to both the component and the signal source. The characteristic impedance of the transmission line is adjusted such that the voltage across the component at or near direct current is about equal to the voltage across the component at the second frequency.

摘要： A signal processing apparatus and method extend the frequency response of a component whose output decreases past a first frequency. The apparatus responds to a signal having a range of frequencies which is applied to a component transmission line and the component transmission line is coupled to the component. The component transmission line is resonant at a second frequency greater than the first frequency and has a source impedance and an input impedance which are not matched. The source impedance is greater than the impedance of the component. The method comprises providing a signal, forming a transmission line which is resonant at the second frequency and coupling the transmission line to both the component and the signal source. The source impedance is adjusted such that the voltage across the component at a low frequency limit is about equal to the voltage across the component at the second frequency.

摘要： An optical package includes a first lens assembly and a second lens assembly aligned such that their optical axes are common. The first lens assembly comprises a divergent light source disposed along the optical axis of a first lens such that the object distance is less than the focal length of the first lens. The second lens assembly comprises a body, having a light acceptance angle less than the angle of divergence of the light source, disposed along the optical axis of a second lens such that the object distance is greater than the focal length of the second lens. The assemblies are disposed such that the images formed by each assembly alone correspond in position along the common axis thereby coupling the light from the source into the body.The package is fabricated by placing the source within the focal length of the first lens and the body is placed outside the focal length of the second lens, forming first and second lens assemblies, respectively. The assemblies are placed along a common axis such that a virtual image of the source, which would be formed by the first assembly alone, and a real image of the body, which would be formed by the second assembly alone, are aligned along the common axis.

摘要： A transducer apparatus is disclosed including a spool member having a body portion and first and second elevated regions formed on the body portion. A piezoelectric film such as a PVDF film surrounds the spool member and is spaced apart from the body portion of the spool member by an elevation of the elevated region, thereby forming a predetermined gap between the piezoelectric film and the body portion of the spool member. The predetermined gap is at least 0.1 mm and enables a predetermined resonance frequency in the piezoelectric film to control the resonance frequency of the transducer. Opposite lateral ends of the piezoelectric film are secured together such that secured ends of the piezoelectric film have substantially the same resonance frequency as a remainder of the piezoelectric film.
