Abstract: Methods and an apparatus to connect a peripheral device to a wireless network access point are provided herein. A host device associated with a wireless network access point stores and obtains a set of wireless credentials related to a wireless network formed by the wireless network access point. The host device opens a connection between the host device and the peripheral device to transmit the set of wireless credentials from the host device to the peripheral device. The host device identifies the peripheral device over the wireless network access point.

Abstract: A method and apparatus for gathering high-quality anatomical audio signals. Practice of the invention, which is illustrated herein in the context of heart-produced signals, is based upon gathering, and competitively processing audio signals collected simultaneously from two adjacent anatomical sites. Competitive processing examines these two signals in light of certain selected “quality” parameters, and thereby selects the better signal at a user-selected point in time.

Abstract: A cardiograph has a remote front end which is connected to a host via a cable. The front end includes a clock and an analog-to-digital converter. The converter periodically holds and samples patient ECG signals. Each conversion takes place within the same fixed length of time. A clock signal is transmitted to the host on one of the conductors in the cable while digital words, each of which represents a sampled value of the ECG signal, are serially transmitted on another conductor in the cable. The clock signal synchronizes ac voltages applied to several power supplies with the sampling rate of the converter so that the ECG signal is sampled at the same phase of each ac voltage applied to the power supplies. The sampling thus occurs at the same phase, and thus the same amplitude, of each periodic noise cycle induced by the power supply electromagnetic fields. The periodic noise is thus removed from the sampled signal while a dc offset equal to the amplitude of the periodic noise at the sampling phase is added.
