Abstract: Devices, systems, and methods are disclosed for improved laser speckle imaging of samples, such as vascularized tissue, for the determination of the rate of movement of light scattering particles within the sample. The system includes a structure adjoining a light source and a photo-sensitive detector. The structure can be positioned adjacent the sample (e.g., coupled to the sample) and configured to orient the light source and detector relative the sample such that surface reflections, including specular reflections and diffuse reflections, are discouraged from entering the detection field of the detector. The separation distance along the structure between the light source and the detector may further enable selective depth penetration into the sample and biased sampling of multiply scattered photons. The system includes an operably coupled processor programmed to derive contrast metrics from the detector and to relate the contrast metrics to a rate of movement of the light scattering particles.

Abstract: Systems, methods, and computer readable storage media provide dynamic chassis and tire status indications associated with a vehicle. Lift axle status data may be graphically represented by a lift axle indicator dynamically provided in a shared notification/messaging space positioned within the driver's line of sight during a lift axle transition. The lift axle indicator may include a side-view representation of the vehicle including a plurality of axle sections indicating the status of each axle. The lift axle indicator may be suppressed when air pressure is stabilized. Additionally, a graphical representation of data associated with statuses (e.g., air pressure, temperature) of each tire may be provided in a top-down view representation of the vehicle including its associated tire/axle configuration and the tire pressure for each tire. The graphical representation may be configured to reflect the correct number of axles and tires per position, and may further include a tractor versus trailer designation.

Abstract: Systems, methods and computer readable storage media provide a flexible and variability-accommodating instrument cluster for display on an in-vehicle screen and a user experience interaction model for providing vehicle status-related information via the instrument cluster. The instrument cluster may be shown in a minimized content view, basic content view, or enhanced content view, wherein each content view may include a varying range of displayed information based on a layout template. The driver can easily scroll between the various content views while driving. The instrument cluster may alternatively be shown in a favorites view, amongst a plurality of preconfigured favorites views associated with different drivers, the favorites view including a user-selected set of gauges in a user-selected layout. A steering wheel-based shortcut control is provided that can be assigned to a changeable parameter and used to toggle the parameter in association with an instrument cluster display element while driving.

Abstract: Disclosed herein are systems, methods, and devices for calibrating contrast measurements from laser speckle imaging systems to accurately determine unknown particle motion characteristics, such as flow rate. The calibration stores to memory calibration data, which may include a set of measurements from samples with known particle characteristics and/or estimates of noise, including the effects on contrast arising from undesired signals unrelated to the unknown particle motion characteristics. The calibration data may be accessed and used to correct an empirical measurement of contrast and/or interpolate a value of the unknown particle motion characteristic. The system may include a light source, photodetector, processor, and memory, which can be combined into a single device, such as a wearable device, for providing calibrated flow measurements. The device may be used, for example, to measure blood flow, cardiac output, and heart rate, and can be used to amplify the pulsatile signal.
