1. A plasmonic chip, comprising:a region of meso-crystal including nanocrystals of silver oxides containing silver peroxides, wherein
the meso-crystal is able to have a function to generate a negative polarity when the meso-crystal is in contact to sera or biological samples, to selectively capture or absorb a cancer-related substance having a positive polarity, and to show an effect of localized surface plasmon resonance when the meso-crystal is irradiated with light.

UTILIZING UPDRAFT FLOW IN A FAN-LESS DUST SENSOR

Honeywell International I...

1. A particulate matter sensor comprising:an air duct;
a light source configured to pass a light beam into the air duct;
an extender, offset from the light beam but connected to the light source, conducting thermal energy generated by the light source to heat air to generate a convective induced airflow in the air duct;
a photodetector configured to detect light of the light beam that is scattered and/or reflected off of particulate matter in the airflow in the air duct; and
a computing device coupled to the photodetector having a processor and a memory storing instructions which, when executed by the processor, determines a mass concentration of particles in the air duct based on an output of the photodetector.

MULTIPLE LIGHT PATHS ARCHITECTURE AND OBSCURATION METHODS FOR SIGNAL AND PERFUSION INDEX OPTIMIZATION

Apple Inc., Cupertino, C...

1. An electronic device comprising:a first light emitter configured to generate a first light to travel a first light path and a second light to travel a second light path, wherein the first light path is in a different direction than the second light path;
a first window overlaying the first light emitter;
a second light emitter configured to generate a third light to travel a third light path and a fourth light to travel a fourth light path, wherein the third light path is in a different direction than the fourth light path;
a second window overlaying the second light emitter, the second window laterally spaced from the first window;
a first light sensor located a first separation distance from the first light emitter and a second separation distance from the second light emitter, the first separation distance being different from the second separation distance, wherein the first light sensor is configured to detect the first light and generate a first signal indicative of the detected first light, and detect the fourth light and generate a fourth signal indicative of the detected fourth light;
a third window overlaying the first light sensor;
a second light sensor located the second separation distance from the first light emitter and the first separation distance from the second light emitter, wherein the second light sensor is configured to detect the second light and generate a second signal indicative of the detected second light, and detect the third light and generate a third signal indicative of the detected third light;
a fourth window overlaying the second light sensor, the fourth window laterally spaced from the third window; and
a processor coupled to the first light sensor and the second light sensor, the processor configured to determine a physiological signal from the first signal and the third signal.
