Preferred compounds include amino acid prodrugs of 3APS for use, including but not limited to, the prevention and treatment of Alzheimer's disease.

Abstract: The disclosure relates to an authentication approach to grant access to a secure service on an electronic device. The authentication approach includes receiving, via an electronic device, a request to access the secure service. The authentication approach includes determining whether the electronic device is positioned at a location that corresponds to a virtual authentication lock. The authentication approach includes displaying, in response to determining the device is positioned at the location that corresponds to the virtual authentication lock, the virtual authentication lock on a display of the electronic device. The authentication approach includes receiving one or more interactions with the virtual authentication lock.

Abstract: A system for tracking the location of an electronic device includes an electronic device and a wireless location tag. The wireless location tag includes a microcontroller unit, and a modular connector interface configured to be communicatively coupled to a port of the electronic device. The wireless location tag is configured to establish an Internet connection to one or more backend electronic devices in response to detecting that the wireless location tag has been communicatively coupled to the port of the electronic device, obtain identifying information that is associated with the electronic device, and identify tag identifying information associated with the wireless location tag. The wireless location tag is also configured to send one or more instructions to the one or more backend electronic devices via the Internet connection, and send one or more ping messages to the one or more backend electronic devices.

Abstract: Techniques and mechanisms to provide satellite communication functionality with an antenna assembly. In an embodiment, a communication device includes an antenna panel (comprising one or more holographic antenna elements), a housing and hardware interfaces which facilitate operation of the communication device has a module of the antenna display. A cross-sectional profile of the housing may conform to a polygon other than any rectangle. A configuration of the housing and hardware interfaces may facilitate the formation of an antenna assembly arrangement other than that of any rectilinear array. In another embodiment, communication devices of the antenna assembly each conform to a triangle or a hexagon.

Abstract: Antennas such as flat panel, leaky wave antennas with directional coupler feeds and waveguides are disclosed. In one example, an antenna includes a surface having antenna elements, a guided wave transmission line, and a coupling surface. The guided wave transmission line provides a guided feed wave. The coupling surface is between and separates the guided wave transmission line and the surface having antenna elements. The coupling surface controls coupling of the guided feed wave to the antenna elements. The coupling surface can also spatially filter the guided feed wave to provide a more uniform power density for the antenna elements. The guided feed wave can be a high power density electromagnetic wave or a density radially decaying electromagnetic wave.

Abstract: This document discloses methods by which an electronic device may determine a navigable path to a destination in an indoor environment without requiring data from any location-based tracking system that is external to the electronic device. The device will receive a graph representation of a map of the indoor environment, with instances of objects represented as nodes of the graph, and with open area paths represented as edges of the graph. The device will determine multiple candidate paths from a starting location to the destination location. Each of the candidate paths will include a set of node-edge combinations that extend from the starting location to the destination location. The processor will identify which of the candidate paths is a shortest path, and it will use that path to identify a navigable path to the destination.
