An apparatus is suitable for measuring a photoplethysmogram (PPG). A photoplethysmographic sensor apparatus may include a casing defining a surface, a plurality of optical emitters configured to emit radiation extending from the surface, at least one photo sensor configured to capture radiation emitted by at least a subset of the plurality of optical emitters. At least a first measurement configuration and a second configuration is defined by the plurality of optical emitters and the at least one photo sensor such that the first and the second measurement configuration provide different measurement channels by including at least partially different sets of at least one optical emitter and at least one photo sensor. The first and second measurement configurations define different spatial configurations, each of which is line symmetric with respect to an imaginary line along the surface.

Current glucose meters provide instantaneous results however are invasive and painful thus causing reduced compliance. A non-invasive, portable, wearable device would be ideal for monitoring and recording and provide a distinct advantage to current glucose monitors.

User comfort control system having non-invasive bio-patch. In some embodiments, a system for providing comfort of a person can include a wearable patch configured to be attached to a skin of the person and sense a biological condition of the skin, and to transmit information representative of the sensed biological condition. The system can further include a controller configured to receive the information and generate a control signal. The system can further include an adjustment element associated with a furniture item implemented to support and provide comfort for the person. The adjustment element can be in communication with the controller and be configured to adjust a comfort level of the furniture item for the person in response to the control signal.

An overdose of opioids can cause the user to stop breathing, resulting in death. A physiological monitoring system monitors respiration based on oxygen saturation readings from a fingertip pulse oximeter in communication with a smart mobile device and sends opioid monitoring information from the smart mobile device to an opioid overdose monitoring service. The opioid overdose monitoring service notifies a first set of contacts when the opioid monitoring information.
