Abstract: Techniques are described for user authentication based on a signal that is transmitted through an individual's body, and detected using device(s) in physical contact with the individual. A signal, such as an electrical signal or a vibrational signal, may be transmitted from a first device and received by a second device that is in physical contact with the individual. The received signal may be employed to determine a body signature for the individual. The body signature may identify the individual among a population of individuals, given the particular alterations to the propagating signal caused by the individual's physiology. Accordingly, the body signature may be employed as a form of biometric data that is useable to authenticate the individual to access a secure area, log in to a device or an application, or for other purposes.

Abstract: Techniques are described for determining and/or verifying the location of a device based on environmental data. A device may provide location information describing its location, e.g., determined using a satellite-based navigation system. Environmental context data (e.g., temperature, air pressure, air quality, pollen count, ambient light, etc.) may also be received from the device, having been generated by sensor(s) incorporated into the device. The environmental context data may be compared to corresponding elements of other context data that is generated independently of the device. Based on the comparison, a confidence metric may be determined that indicates a level of confidence that the device's communicated location is its actual location. The confidence metric may be employed to make a security determination regarding a user of the device.

Abstract: A mounting system for solar panels that is adjustable to allow for ease of installation. An adjustable leg or strut includes a telescoping portion that is connected to a base by a compound ball joint. At an upper end, an angularly adjustable bracket allows for connection to a rail for supporting the solar panel. In a typical installation, two series of adjustable legs are used to support two rails at differing heights to support a panel in a desired position. The adjustable nature of the components allows for a faster installation compared to known solar panel mounting systems.
