Abstract: The present disclosure generally relates to logging health-related events and for health-related coaching. In some embodiments, an event is logged by associating an action with a specific time and a user sentiment. In some embodiments, an event challenge, associated with a log entry, is transmitted to an external electronic device.

Abstract: A technique of controlling a transducer. The method includes transmitting signals to the transducer, receiving signals from the transducer, and automatically adjusting the signals transmitted to the transducer based on characteristic of the signals received from the transducer. The transducer may be an ultrasound transducer. The adjustment of the signal may be performed at least in part by dynamically updating a signal threshold, for example via a proportional-integral-derivative or other type of control loop implemented at least in part by a field programmable gate array. One or more visual, audio, and haptic feedback to a user based on the signals received from the transducer. The signal may be also included a coded excitation communication and/or a Doppler signal. Automatically adjusting the signals transmitted to the transducer may achieve synchronization with an external imaging system. Also, systems that perform the technique.

Abstract: A novel ultrasound device for needle procedures is disclosed that comprises a needle with an integrated ultrasound transducer. The transducer may be part of a drop-in, self contained beacon unit that fits within the needle shaft. The transducer may alternatively include electrical leads connectable to an electrical subsystem housed within an adapter that is connectable to a handle. Alternatively, the electrical subsystem may be housed within a handle connectable to the needle by a bayonet-mount configuration, a slide-and-click configuration, or a cartridge configuration. The electrical subsystem is preferably configured to control when the transducer emits an ultrasound pulse. The handle may include all or part of a vacuum means for applying negative pressure to tissue disposed near a tissue sample aperture.
