The invention relates to a method of detecting the presence of cancer in a subject based on a panel of biomarkers comprising Hexanal, Heptanal, Octanal, Decanal, Benzaldehyde, Phenylacetaldehyde, Undecane and Benzoic acid in exhaled breath obtained from a subject. The disclosure also teaches a method of detecting tuberculosis and to distinguish the detection of tuberculosis from cancer or to distinguish the detection of cancer from tuberculosis.

A vehicle control system with impaired driver prevention and biometric detection includes a vehicle with an ignition interlock circuit and one or more vehicle electrical systems, a detection device with an internal sensor system, and a mobile device having and one or more biometric sensors. The system operates by initiating a vehicle start command via the mobile device, prompting a user for a scan, receiving the scan from the detection device, whereby the scan includes at least a blood alcohol content percentage of the user, acquiring a sensed biometric image via the biometric sensors of the mobile device, and comparing the sensed biometric image to one or more stored biometric images. If the biometric image does not match a stored biometric image, or if the scan includes a blood alcohol content above a threshold value, then the vehicle start command is canceled.

A measuring vessel in which a gas to be analyzed by spectrometry is intended to flow, the vessel being in the form of a hollow tube provided with a reflective material forming an optical-reflection layer, including a hollow tube is produced from a non-metallic material, and a removable supple optical article is applied against the internal surface of the hollow tube, the article including a supple flexible support, one face of the support being covered with a reflective metal material, the article being inserted in the tube so that the reflective metal material forms the optical-reflection layer.

A method of detection of an analyte includes using a detector array having at least two detector elements that can emit electromagnetic waves, and selectively connecting a transmit circuit to any one or more of the at least two detector elements of the detector array. At least one transmit signal is generated using the transmit circuit, where the at least one transmit signal is in a radio or microwave frequency or visible range of the electromagnetic spectrum. The at least one transmit signal is transmitted into a target containing at least one analyte of interest using the one or more of the at least two detector elements connected to the transmit circuit. A receive circuit is selectively connected to a different one or more of the at least two detector elements of the detector array, and the receive circuit and the different one or more of the at least two detector elements of the detector array are used to detect a response resulting from transmission of the at least one transmit signal into the target containing the at least one analyte of interest.
