Abstract: The invention relates to an SPR sensor system comprising a number of SPR  sensor surfaces (120), arranged in a two-dimensional raster lying on a plane, on a substrate (10, 20), whereby the SPR sensor surfaces (120) are parallel to the plane and radiation, which under certain physical conditions can generate surface plasmons in the SPR surfaces (120), can be guided through the substrate (10, 20), in order to be reflected from the SPR sensor surfaces (120). The invention further comprises separating agents (110), for separation of the individual SPR sensor surfaces (120) from the neighbouring surfaces (120), whereby the separating agents (110) and the SPR sensor surfaces (120) are arranged such that, at least whilst no surface plasmon resonance in the SPR sensor surfaces (120) occurs, the radiation (40), guided through the substrate (10, 20), is reflected in a different manner in the area of the separating agents, to that in the area for the SPR sensor surfaces (120), such that, at least whilst no surface plasmon resonance in the SPR sensor surfaces (120) occurs, it is possible to distinguish a contrast between the separating agents (110) and the SPR surface sensors (120), in the radiation reflected from the separating agents (110) and from the SPR surface sensors (120).

Abstract: A microphone has a hollow cylindrical housing with a lateral axis, and two non-parallel elliptical end faces oriented mirror symmetrically with respect to a plane perpendicular to the lateral axis. Two circular transducer mounting plates extend across the housing, adjacent the respective end faces, perpendicular to the lateral axis and carry two microphone transducers mounted centrally in the mounting plates for receiving sound from outside the transducer mounting plates. The ends of the housing are covered with end panels of an air-pervious material. Sound-damping tragus pads are secured to inner faces of the end panels, with each tragus pad having an elliptical periphery spaced from the housing to provide an undamped elliptical path for the transmission of sound. In use, the microphone is normally positioned with the lateral axis horizontal and the long axes of the two elliptical end faces converging downwardly to a front side of the microphone to meet at a dihedral angle of 70 degrees 32 minutes. These end faces are identified as 'right' and 'left' end faces. The microphone in one application is an essential component of a hearing assist or aid also including a mount for mounting the housing on an eyeglass frame such that when worn, the lateral axis is substantially horizontal and the elliptical end faces converge forwardly and downwardly. Two amplifiers are coupled to the respective microphone transducers and drive respective earpiece transducers. In another version of the hearing assist or aid the microphone is divided into two separate, left and right components that may be mounted on opposite sides of a human head with the lateral axes aligned and the elliptical end faces converging forwardly and downwardly. The two components of this hearing assist may be located on or adjacent to the lateral zero axis of the human head, thus providing a more accurate representation of the surrounding sound field. Also disclosed is an improved loudspeaker system.

Abstract: A sharp-cutoff VHF elliptic filter includes a folded signal path and internally coupled feedback in a conductive enclosure. Sized for the power requirements of commercial television broadcast transmission, the filter implements the elliptic filter equation through use of cavities, resonators, and couplers. The negative feedback required by the elliptic filter equation is implemented by folding the RF signal path and coupling the feedback energy through a gap in an internal septum to sum negatively with the signal in the main signal path. The elliptic filter can have an interdigital configuration, which puts successive resonators on opposite walls of the enclosure and couples the signal at half-wavelength spacing. The elliptic filter can alternatively have a comb line configuration, which places all resonators on one wall and employs full-wavelength spacing.
