Abstract: During manufacture and packaging of items whose authenticity is to be verified, the items are marked with individual item characteristics, and placed in a package. A first item authentication code is determined from the individual item characteristics of the marked items. A first package authentication code is generated, and the package is marked with the first package authentication code. During item authentication in the field, an image of the package and the marked items is captured, a second package authentication code and the individual item characteristics are extracted from the captured image, the extracted individual item characteristics are processed to generate a second item authentication code, and the authenticity of the marked items is verified by matching the first and second package authentication codes and by matching the first and second item authentication codes.

Abstract: A physiology monitoring system is provided for reducing the risk of sudden unexpected infant death in infants and to monitor physiological parameters in both infants and adults. An embodiment of the monitoring system includes a belt dimensioned to encircle a patient's chest; an accelerometer configured to detect inhale/exhale motions of the patient's chest; a gyroscopic sensor configured to detect supine/prone orientation of the patient; a controller configured for receiving signals from the accelerometer and gyroscopic sensor and determining a risk to the patient based on the received signals; and an e-paper display. The e-paper display being coupled to the control circuit and configured to display instructional messages to a caregiver. Additionally, a power source provides energizing power to the accelerometer, gyroscopic sensor, controller and e-paper display for a minimum period of one year.

Abstract: A gas or particulate sensor is provided for the detection of at least two target gases and/or particulates. The sensor comprises: a chamber for containing a gas sample under test; a first optical measurement channel configured for the detection of a first target gas or particulate within the gas sample, and a second optical measurement channel configured for the detection of a second target gas or particulate within the gas sample, each optical measurement channel comprising a respective optopair which comprises a radiation source adapted to emit radiation and a radiation detector adapted to output a signal in response to detected radiation; and focusing optics able to form an image of an object.
