    摘要： An apparatus for raising and lowering a payload, particularly a chair and its user to provide assistance with the sit-to-stand task. The apparatus comprises a platform, a left lifter assembly, a right lifter assembly, means to power both lifter assemblies, and means to control the raising and lowering thereof. Means to sense and correct sideways tilt, desirable to preclude excessive tilt if one of the lifters fails, are described. The user may use an existing, favorite chair, including a reclining chair, which is placed upon the platform without modification. In a low position, the platform is very close to the floor, providing comfort during sitting. In a high position, the platform is greatly elevated, to provide a full measure of sit-to-stand assistance. The apparatus doesn't interfere with posterior foot placement during the sit-to-stand process, and doesn't interfere with reclining while sitting. The apparatus is easily deployable, movable, and storable.

    摘要： An apparatus for raising and lowering a payload, particularly a chair and its user to provide assistance with the sit-to-stand task. The apparatus comprises a base, a platform, linkages attached between base and platform to allow only vertical motion therebetween, an inflatable bag also situated between base and platform, and a source of pressurized fluid such as compressed air, whereby the bag is inflated and deflated to raise and lower the platform. The user may use an existing, favorite chair, including a reclining chair, which is placed upon the platform without modification. In a low position, the platform is quite close to the floor, providing comfort during sitting. In a high position, the platform is greatly elevated, to provide a full measure of sit-to-stand assistance. The apparatus is compact, doesn't interfere with reclining or rocking while sitting, and is easily deployable, movable, and storable.

    摘要： The invention comprises a transducer, computer hardware, and software. The computer hardware contains a waveform-input device. The transducer (such as a microphone) converts a signal (such as sound waves) into a time-varying voltage. The waveform-input device periodically samples this voltage and digitizes each sample, thereby producing an array of N numbers in the memory of the computer that represent a small snippet of the signal measured over a time interval &Dgr;tmeas. Snippets are typically measured one after the other at a repetition rate that is inversely related to &Dgr;tmeas. The software, also stored in the memory of the computer, and executed using its central processing unit, includes a spectral-analysis process that analyzes the frequency content of each snippet and produces an associated spectrum. The software also includes a novel note-analysis process that analyzes the spectrum and extracts from it the pitch and timbre of the principal musical note contained therein. The process works for any spectrum, including cases where the fundamental frequency of the note is missing. The software further includes novel processes to visualize graphically the pitch and the timbre.
