Representative methods, apparatus and systems are disclosed for blood pressure and other vital sign monitoring using arterial applanation tonometry, including ambulatory blood pressure and other vital sign monitoring. A representative system comprises a wearable apparatus. The various embodiments measure blood pressure and other vital sign monitoring using a plurality of pressure sensors of a pressure sensor array, with one or more of the pressure sensorsapplanating an artery, such as a radial artery. In a first embodiment, a pressure sensor signal is utilized which has the highest cross-coherence with the signals of its nearest pressure sensor neighbors of the pressure sensor array. In a second embodiment, Kalman filtering is utilized for the pressure sensor signals from the pressure sensor array.

Tonometry based blood pressure measurements using a two-dimensional force sensor array

A medicine container includes a controller and a scale connected with the controller. The scale is configured to measure a weight of a content contained in the medicine container. An inertial measurement unit connects with the controller. The inertial measurement unit is configured to detect a position of the medicine container. The controller is configured to process the position information to ensure that the container is located in an upright position before the weight measurement is considered.

System and method for tracking content in a medicine container

A system and a method include a medicine container having a bottle and a cap. The medicine container includes a controller and can include a camera located in the cap. The container can include a scale in the base. The controller controls the camera to take an image of the inside of the container to detect the contents, along with a weight measurement to determine usage of the content. A memory connects with the camera and the scale to store the image and weight data. The container can communicate data with a backend server using a wired or wireless connection upon a trigger event. Multiple containers can be connected to form a network of containers.
