摘要： The present invention increases the aperture size of a microphone array by introducing a diffracting structure into the interior of a microphone array. The diffracting structure within the array modifies both the amplitude and phase of the acoustic signal reaching the microphones. The diffracting structure increases acoustic shadowing along with the signal's travel time around the structure. The diffracting structure in the array effectively increases the aperture size of the array and thereby increases the directivity of the array. Constructing the surface of the diffracting structure such that surface waves can form over the surface further increases the travel time and modifies the amplitude of the acoustical signal thereby allowing a larger effective aperture for the array.

摘要： A method and apparatus for reducing the acoustic coupling between a sound receiving transducer and a sound transmitting transducer is disclosed. A housing, wherein the receiving transducer and the transmitting transducer are mounted, is provided to increase the acoustic separation between the receiving transducer and the transmitting transducer. The housing has a surface, which may have an acoustic impedance condition, which is preferably resistive. The housing may further act as a barrier structure between the receiving transducer and the transmitting transducer.

摘要： A digital hearing aid is provided that includes front and rear microphones, a sound processor, and a speaker. Embodiments of the digital hearing aid include an occlusion subsystem, and a directional processor and headroom expander. The front microphone receives a front microphone acoustical signal and generates a front microphone analog signal. The rear microphone receives a rear microphone acoustical signal and generates a rear microphone analog signal. The front and rear microphone analog signals are converted into the digital domain, and at least the front microphone signal is coupled to the sound processor. The sound processor selectively modifies the signal characteristics and generates a processed signal. The processed signal is coupled to the speaker which converts the signal to an acoustical hearing aid output signal that is directed into the ear canal of the digital hearing aid user. The occlusion sub-system compensates for the amplification of the digital hearing aid user's own voice within the ear canal. The directional processor and headroom expander optimizes the gain applied to the acoustical signals received by the digital hearing aid and combine the amplified signals into a directionally-sensitive response.

The wafer carrier is rotatable with the rotating motion imparted to a semi-conductor wafer held thereon. In first embodiment, the machine further includes a rotatable polishing pad having an upper surface divided into a plurality of wedge-shaped sections, including an abrasion section and a polishing section. The abrasion section has a relatively rough texture and the polishing section has a relatively fine texture as compared to each other. In an alternative embodiment, the pad includes an underlayer and surface layer. The surface layer includes two sections of differing hardness, both of which are harder than the underlayer. Alternatively, the surface layer may include one relatively hard section, and the underlayer may include two sections, one of which has the same hardness as the surface layer and the other of which is softer than the surface layer. In a further embodiment, the polishing pad has an annular shape, and a chemical processing table is disposed within the open central region of the pad.

摘要： An improved etch behavior is promoted to generate vertical sidewalls for fuse links that will promote reliable and repeatable laser cutting of the fuse links. In one embodiment, dummy structures are added adjacent to fuse links in order to obtain the vertical sidewalls for reliable fuse deletion. The dummy structures form no part of the fuse or circuit structure but, because of the proximity of the dummy structures to the fuse links, vertical sidewalls are promoted in a reactive ion etch which is used to form the fuse array. In another embodiment, the vertical sidewalls of the fuse links are achieved in a damascene process in which grooves are formed in an oxide layer and filled with a metal. These grooves correspond to the fuse links and alternating dummy structures. Once filled, the surface is planarized using a chemical-mechanical process. The dummy structures provide reinforcement for the metallization (metal and dielectric film), maintaining the integrity of the metallization. In both embodiments, the vertical sidewalls and constant height of the resulting fuse links promote reliable laser cutting.

摘要： A gray level mask suitable for photolithography is constructed of a transparent glass substrate which supports plural levels of materials having different optical transmissivities. In the case of a mask employing only two of these levels, one level may be constructed of a glass made partially transmissive by substitution of silver ions in place of metal ions of alkali metal silicates employed in the construction of the glass. The second layer may be made opaque by construction of the layer of a metal such as chromium. The mask is fabricated with the aid of a photoresist structure which is etched in specific regions by photolithographic masking to enable selective etching of exposed regions of the level of materials of differing optical transmissivities. Various etches are employed for selective etching of the photoresist, the metal of one of the layers, and the glass of the other of the layers. The etches include plasma etch with chloride ions to attack the chromium of the opaque layer, compounds of fluorine to attack the glass layer, and reactive ion etching with oxygen to attack the photoresist structure. Also, developer is employed for etching on hardened regions of resist in the photoresist structure.
