  • Publication number: 20230190160
    Abstract: A system and method for collection and interpretation of data for determining impairment by intoxicant(s) in a subject at the point of collection utilizes of multiple sensors which may comprise both a live-cell assay in a disposable cartridge for determining the presence of intoxicant(s) and an eye scanner for determining vital signs and neurological state of the subject. The cartridge may be equipped to intake a sample, process it, and/or interact it with one or more eukaryotic cell-based biosensors. A cartridge may function as an optical interface to relay signals from the biosensors to a detector. The eye scanner may be equipped with optical sensors for the detecting both vital signs and neurological state. Each optical sensor may be spectrally filtered to identify a biomarker or set of biomarkers. Another method utilizes the eye scanner to train a model to identify additional biomarkers within the live-cell assay on a cartridge to increase the specificity for impairment by the primary analyte.

  • Patent number: 10480602
    Abstract: A disc brake including a brake actuation mechanism and an adjustment mechanism, which is configured to provide, in addition to a reduction of the clearance between a brake pad and a brake disc during brake application, a further increase of the clearance during brake release motion with a value, which may be smaller, equal or larger than the previous clearance reduction. The brake actuation mechanism for that purpose could provide a different regulator unit. Moreover, the invention suggests a method for adjusting the clearance between a brake pad and a brake disc providing a clearance increase during brake release motion, accordingly.

  • Patent number: 7389858
    Abstract: The present invention relates to a disc brake having a housing, a clamping device, a push rod, and a self-activating adjustment device, whereby the adjustment device includes a first subassembly and a second subassembly. According to the invention the adjustment device includes an assembling joint, which makes possible the transmission of a rotary motion from the first subassembly to the second subassembly, whereby the assembling joint allows an axial relative motion between the first subassembly and the second subassembly, whereby the assembling joint permits an axial relative motion between the first subassembly and the second subassembly of the adjustment device. According to a particular embodiment of the invention, a misalignment of the push rod inside a place, which lies parallel to the brake disc, can occur with respect to the housing, without resulting in jamming of the cylindrical element with respect to the push rod and housing.
