Abstract: A protective case for enveloping a smartphone incorporates at least one sensor for detecting stimuli arriving from outside of the smartphone. The case and the phone form an integral unit that possess extra features than the phone alone wouldn't have. The sensor is supplemented by a signal conditioning and interface electronic circuit for communicating the sensed information to the smartphone inner processor. The communication is via a wired connection to the smartphone's connector or wireless via a radio waves or optical link. For expanding versatility of the smartphone, the sensors may be adapted for detecting non-contact temperature, light, ultrasonic, smell, material composition, human vital signs, and other signals.

Abstract: A hand-held mobile communication device, such as smart telephone, incorporating sensors and signal conditioning modules for measuring signals from external sources of electromagnetic radiation (EMR) in the low, radio, ultraviolet, and infrared spectral ranges. These include the detector for receiving and monitoring electromagnetic fields originating from various external sources of radiation that pose potential health hazards or may interfere with various electronic devices. The mobile phone equipped with such sensors could alternate between communication and monitoring functions. Other integrated EMR sensors are a photodiode for the ultraviolet detection to monitor the user's sun exposure and a thermopile for non-contact measurement of temperature of humans or inanimate objects.
