Abstract: An amplified sound system wherein a microphone is maintained at a desired acoustic zone in front of a speaker for enhancing performance in receiving sound emanated from said speaker. The system comprises a speaker cabinet containing at least one speaker, a microphone mount and a microphone for receiving sound emanated from said speaker. The microphone mount has an elongated support member for supporting said microphone at a desired spacial distance in front of the speaker. The support member has a first end attached to the speaker cabinet, and a second end on which the microphone is carried so that the microphone is positioned in a desired acoustic zone for collecting sound emanated from said speaker.

Abstract: A memory element of the present invention is split to minimize the magnitude of electrical current flowing therethrough as the split memory element is being heated to its transitional temperature, thereby permitting the cross-sectional area of the lead wires used to conduct an electric current to the memory element to be minimized. The split memory element includes a tip member and first and second strip members aligned in side-by-side relation. Each of the tip member, first strip member, and second strip member are made of a shape-memory alloy and have a characteristic internal structure. Each strip member includes a shape-memory portion coupled to the tip member, a lead-attachment portion, and partition means for interconnecting the shape-memory and lead-attachment portions.

Abstract: A memory element made of a shape-memory alloy includes lead-attachment and shape-memory portions and a partition interconnecting such portions. The lead-attachment and shape-memory portions are comprised of characteristic internal structures, while the partition is comprised of an internal structure dissimilar to the characteristic internal structure of at least one of the lead-attachment and shape-memory portions. Shape-memory effect characteristics of the shape-memory portion are preserved to maintain the memory function of the memory element by configuring the dissimilar internal structure to block transmigration from the lead-attachment to the shape-memory portions of selected contaminant material existing in the lead-attachment portion. The partition functions as a contaminant filter to control the concentration of contaminant material in the shape-memory portion, thereby enhancing the durability of the memory element.
