A modular patient monitor provides a multipurpose, scalable solution for various patient monitoring applications. In an embodiment, a modular patient monitor utilizes multiple wavelength optical sensor and/or acoustic sensor technologies to provide blood constituent monitoring and acoustic respiration monitoring (ARM) at its core, including pulse oximetry parameters and additional blood parameter measurements such as carboxyhemoglobin (HbCO) and methemoglobin (HbMet). Expansion modules provide blood pressure BP, blood glucose, ECG, CO2, depth of sedation and cerebral oximetry to name a few. Aspects of the present disclosure also include a transport dock for providing enhanced portability and functionally to handheld monitors. In an embodiment, the transport dock provides one or more docking interfaces for placing monitoring components in communication with other monitoring components. In an embodiment, the transport dock attaches to the modular patient monitor.

This disclosure includes techniques for controlling smart home devices upon entering a home with a fingerprint sensor in a doorbell device. After capturing a fingerprint of a digit of a guest and sending the fingerprint to a server device, the server device matches the fingerprint of the digit to an entry in a guest fingerprint database for a first user. The server device sends an operational command to a smart home device separate from the doorbell device and located at a same premises as the doorbell device. In response to receiving the operational command from the server device, the smart home device performs an action corresponding to the operational command.
