Abstract: The present invention features the application of a simple, inductively-coupled measurement system into the cap of standard laboratory sample tubes, thus enabling continuous, wireless ionic sensing of a bevy of samples. The system may be powered by a compact Class E amplifier using inductive coupling via a designed resonance frequency of 1 MHz. Other frequencies can be used, such as the popular near-field communication (NFC) frequency of 13.66 MHz. Signals are transmitted back via load modulation at frequencies a fraction of the power carrier frequency, thus allowing for extraction of the signal frequency. Results clearly show that modulation frequency tracks closely with open circuit potential, and the system features good sensitivity and linearity. This system holds promise for a host of applications.

Abstract: An implant delivery system can be used to deliver an implant into a body. The implant delivery system can include an inflation tube and a tubular member surrounding the inflation tube. The inflation tube can be used to provide an inflation medium to the implant. The tubular member can have a distal tip and an opening spaced from the tip to allow the implant to be released through the opening into an anatomical structure within the body.

Abstract: A wearable device that wirelessly automatically acquires and processes signals indicative of a condition of subject's health. The device is adapted to wirelessly transmit the processed signals and other information to a suitable analytic and/or storage device where the subject's condition can be analyzed and/or stored. The signals could be ECG signals and the condition could be the health of the subject's heart.

Abstract: Methods, systems, and apparatus for delivering a message to a visually impaired person. The method includes providing a device including a housing with an inner chamber and an outer surface, a power source, and a sound producing device coupled to the power source. The power source and sound producing device are contained within the inner chamber of the housing. Providing a mechanism to activate the sound producing device in the housing. Providing a braille message on the outer surface of the housing. This and other implementations can each optionally include one or more of the following features.

Abstract: At least one sensor in a wearable device worn by a user may be configured to detect at least one of an electrocardiogram (ECG) signal and arterial pulse (or photoplethysmogram (PPG)) signal. At least one processing circuit may process the ECG signal, the pulse/PPG signal, or both to determine at least one of a pulse transit time (PTT) and pulse arrival time (PAT). The at least one processing circuit may determine a blood pressure (BP) of the user from the PTT, the PAT, or both.
