Abstract: A computing device implemented method of detecting compliance in wearing of head-worn Personal Protection Equipment (PPE) is described. The method includes producing one or more biometric sensor signals containing physiological information of a wearer of the PPE using one or more biometric sensors and processing, by the computing device, the physiological information of the one or more biometric sensor signals to detect compliance in wearing of the PPE and generating an indication of compliance in wearing of the PPE.

Abstract: An apparatus for capturing an image of an object on a platen and including a platen having a surface for receiving the object, wherein the platen is transmissive to an optical wavelength of light, an illumination module configured to illuminate at least a portion of the object with light from an illumination source, and an optical sensing module configured to receive the light from the illumination source after the light interacts with the at least a portion of the object. The light from the illumination source is spatially patterned prior to reaching the object. The illumination module can be configured to create the spatially patterned illumination and/or the platen may include a patterned optical coating creating the spatially patterned illumination. The spatially patterned illumination can include a plurality of discrete areas (e.g., a stepped pattern) of different illumination intensity and/or a gradient of different illumination intensity.

Abstract: An information handling system (IHS) includes a coffee design application. The IHS receives first input information from a user that specifies a coffee design mode. The IHS receives second input information from a user that enables the IHS to define a unitless brew formula line ratio of water weight to coffee weight. The IHS displays a brew formula line on a universal brewing control chart graph, the brew formula line being dependent on the brew formula ratio. The IHS operates in a selected one of a brew water volume mode, a desired coffee yield mode and a ground coffee weight mode. The IHS converts input values to selected units and resultant output values to selected units in real time. The IHS projects a target total dissolved solids (TDS) % value on the brew formula line and plots a universal brewing control chart.

Abstract: A coffee refractometer includes a prism that receives a brewed coffee sample, thus forming a prism-sample interface. A processor or microcontroller controls a light source to provide incident light to the prism-sample interface. The prism-sample interface refracts light toward a photodetector. A temperature sensor provides temperature information to the processor. The refractometer includes a memory store that stores a TDS formula that expresses the TDS of brewed coffee as a function of the index of refraction (ns) of brewed coffee and the temperature of brewed coffee. The processor determines the TDS of the brewed coffee sample by accessing the TDS formula in the memory store and employing the determined index of refraction (ns) of the brewed coffee sample to find the TDS from the TDS formula. The refractometer displays the resultant TDS % on a display of the refractometer and/or transmits such information to an information handling system.
