Abstract: In one embodiment, an apparatus comprises a storage device to receive, from a computing host, a request to append data to a data log. The storage device is further to identify a memory location after a last segment of the data log, append the data to the data log by writing the data to the memory location after the last segment of the data log, and provide, to the computing host, a key comprising an identification of the memory location at which the data was appended to the data log.

Abstract: An apparatus for audio reproduction, specifically, transduction of electrical signals into acoustic signals, or sound waves, which minimizes acoustic impedance matching problems and distortion by mounting a diaphragm inside the body of a horn having a mouth for passage of sound waves at the end of the horn on one side of the diaphragm and an open end at the end of the horn on the other side of the diaphragm. The diaphragm is mounted in a voice coil collar having a voice coil wound therearound, and smaller, secondary magnets are mounted to the collar on both sides of the diaphragm. The horn is provided with large, primary magnets on either side of the collar, and the orientation of the magnets causes the collar to be suspended at exactly the midpoint therebetween. When current is applied to the coil, the collar, carrying the diaphragm, reciprocates within the horn to produce sound waves out of the mouth of the horn, the open end at the other end of the horn acts to equalize air pressure within the horn.
