Abstract: A method, apparatus, computer-readable medium, and/or system may comprise a server having a first processor, a database, and first memory storing computer-executable instructions. The system may comprise a self-service device having a second processor, a plurality of sensors configured to capture images, and second memory storing computer-executable instructions that, when executed by the second processor, cause the self-service device to detect a start of user activity at the self-service device. In response to detecting the start of the user activity at the self-service device, the self-service device may capture, by one or more of the plurality of sensors, a plurality of images of the user activity at the self-service device. The self-service device may detect an end of the user activity at the self-service device. In response to detecting the end of the user activity at the self-service device, the self-service device may generate data indicative of the user activity at the self-service device.

Abstract: The invention relates to a heat exchanger for an EGR (Exhaust Gas Recirculation) system, comprising a tube bundle of flat tubes, configured by combining two plates incorporating specific protrusions distributed according to the direction of the tube. These protrusions in both plates are in contact with one another or attached such that they establish internal channels. The present invention is characterized by the presence of either transverse projections or of transverse deviations generating disturbances in the flow through side walls of the internal channels, increasing the turbulence of the flow through said channels and thereby increasing heat exchange by convection.

Abstract: The present invention relates to a heat exchange device suitable for cooling recirculated exhaust gases in an EGR (Exhaust Gas Recirculation) system. The invention is characterized by a configuration that allows incorporating the heat exchanger in very small spaces and with the recirculated exhaust gas inlets and outlets not necessarily being aligned. It is also characterized by an inner configuration based on the stack of flat tubes configured by means of die-cut and stamped sheets configuring a complex path of the fluid to be cooled. According to embodiments, the invention is incorporated in a cavity of the engine block of an internal combustion engine with fluid communication with the liquid coolant. The present invention has an impact on protecting the environment.

Abstract: The present invention provides a hygienic pad enabled not only to collect human discharges when a man or a woman uses the pad, but also to detect reactants contained in the discharges. The detected reactants are indicators of medical conditions. Means to detect the reactants are incorporated into the hygienic pad.
