Abstract: An ATM is configured to interact with a mobile device and provide user access to one or more of the banking services available at the ATM using the mobile device. Banking-related information may be viewed and/or input at the ATM using the mobile device. The ATM may have multiple vertical levels of deposit slots, withdrawal trays and/or receipt dispensers. A level at the ATM at which the user interacts with the ATM for deposits, withdrawals, or receipts may be selected. The level may be specified by the user of the mobile device, at the ATM or using the mobile device, or may be determined by the ATM.

Abstract: A screen-less automated teller machine (ATM) may be configured to interact with a mobile device. The ATM may automatically detect the presence of the mobile device in a vicinity of the ATM and initiate contact with the mobile device, or a mobile device may initiate contact with the ATM. After verifying user permission to access the ATM, the mobile device may be enabled to provide user access to one or more of the banking services available at the ATM using the mobile device. As the ATM is screen-less, banking-related information may be viewed and/or input at the ATM using the mobile device. An application on the mobile device may be used to access and interact with the ATM using the mobile device.

The microfluidic diagnostic device also includes a first cover adhered to the first opposing surface to seal the first flow channels, a second cover adhered to the second opposing surface to seal the second flow channels, and one or more access ports in fluid communication with the continuous 3D flow pathway for introducing liquid reagent(s) and/or a sample into the polymeric body.

Abstract: Methods for banking at an automated teller machine (ATM) using a mobile device. The ATM may automatically detect the presence of the mobile device in a vicinity of the ATM and initiate contact with the mobile device, or a mobile device may initiate contact with the ATM. After verifying user permission to access the ATM, the mobile device may be enabled to provide user access to one or more of the banking services available at the ATM using the mobile device and to view banking-related information on the mobile device. A mobile application on the mobile device may be used to access the ATM using the mobile device. While a mobile device is accessing the ATM, a screen on the ATM may become inactive for banking services and the option to select banking services directly at the ATM may be disabled.

Abstract: An active thermal management system for electronic devices comprises: a heat spreader having an internal channel; a thermally conductive body moveably positioned in the internal channel; and two or more electronic devices in thermal contact with a back surface of the heat spreader and positioned adjacent to the internal channel. A location of the thermally conductive body within the internal channel determines a path for heat flow from the back surface to a front surface of the heat spreader. The location of the thermally conductive body within the internal channel may be selected to minimize a temperature differential (?T) between the electronic devices.

Abstract: Described herein are flexible superhydrophobic films. Also described are methods for imparting superhydrophobicity to a variety of objects, for example objects having any shape or surface contours. For specific applications, the flexible superhydrophobic films include an adhesive backing layer, useful for attaching the film to objects. Some of the films described herein allow for selective control over the wettability of a surface by flexing the film, for example flexing the film results in a more wettable film, a less wettable film or a film having unchanged wettability. Flexible superhydrophobic films described herein also include films which maintain their superhydrophobicity when deformed into a concave or convex curvature.

Abstract: A method of making a three-dimensional porous device entails providing a substrate having a conductive pattern on a surface thereof, and depositing a colloidal solution comprising a plurality of microparticles onto the surface, where the microparticles assemble into a lattice structure. Interstices of the lattice structure are infiltrated with a conductive material, which propagates through the interstices in a direction away from the substrate to reach a predetermined thickness. The conductive material spans an area of the surface overlaid by the conductive pattern. The microparticles are removed to form voids in the conductive material, thereby forming a conductive porous structure having the predetermined thickness and a lateral size and shape defined by the conductive pattern.
