Abstract: An embodiment of an auscultation device can be constructed using electronic components to provide improved acquisition, processing, and communication of sound signals. An input device can be used for detecting sounds, and electrical signals representing the sounds can be processed and transmitted via Bluetooth and/or another form of wireless communication. Such embodiments can employ, at least in part, one or more of several commercially available wireless receiver devices, such as, without limitation, headsets and headphones, mobile phones, PDAs and/or other handheld devices, desktop, laptop, palmtop, and/or tablet computers and/or other computer devices and/or electronic devices.

Abstract: A apparatus and method for non-invasively measuring blood pressure. Cuff pressure and oscillometric signals are generated. The signals are conditioned by a plurality of linear filters to remove artifacts and local trends. Rank-order filters are applied to the conditioned oscillometric signal to detect upper and lower envelops. The systolic blood pressure and diastolic blood pressure are calculated using a plurality of multidimensional threshold vectors.
