Abstract: The present disclosure relates to fuel cells, in particular to high-temperature air-cooled fuel cells. A fuel cell 1 comprises a bipolar plate 2 and a membrane-electrode assembly 3. The bipolar plate 2 comprises an anode plate 5, a cathode plate 6 and a layer 7 of air cooling channels between the anode plate 5 and the cathode plate 6. Channels for an oxygen-containing gas are made in the cathode plate 6. Channels 10 for hydrogen are made in the anode plate 5, which are covered by the membrane-electrode assembly 3 contacting the anode plate 5. A fuel cell stack comprises at least two fuel cells, wherein the membrane-electrode assembly of one fuel cell contacts the anode plate of said one fuel cell, thus covering the channels for hydrogen, and contacts the cathode plate of said another fuel cell, which adjoins said one fuel cell, thus covering the channels for an oxygen-containing gas.

Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Abstract: Techniques for training neural networks in accordance with an adaptive loss scaling scheme are disclosed. One aspect of the present disclosure relates to a method of training a neural network including a plurality of layers, including determining, by one or more processors, layer-wise loss scale factors for the respective layers and updating, by the one or more processors, parameters for the layers in accordance with error gradients for the layers, wherein the error gradients are scaled with the corresponding layer-wise loss scale factors.

Abstract: An antenna floor tile for a raised floor system comprises a frame; an insert supported by the frame, the insert including a top surface; a recess disposed below the top surface; an antenna attached to the insert within the recess; and a protective layer disposed over the antenna.

Abstract: Systems and methods may provide for monitoring an input audio signal from an onboard microphone of a mobile device while a host processor of the mobile device is in a standby mode. Additionally, a predetermined audio pattern may be identified in the input audio signal and a device location session may be triggered with respect to the mobile device based on the predetermined audio pattern. In one example, an output audio signal is generated during the device location session.

Abstract: Various methods and systems for modifying an indicator corresponding to an alert are described herein. One example method includes detecting an alert with a computing device. The method also includes monitoring a noise level in an environment surrounding a computing device. In addition, the method includes modifying the indicator corresponding to the alert based on the noise level. Furthermore, the method includes providing the modified indicator corresponding to the alert.
