Abstract: A system for location-aware authentication is configured to receive an authentication request associated with an identifier of a user for accessing an application and retrieves user information associated with the identifier and the application. The system then determines that the user information includes a geofence and information associated with a device of the user. Based on the geofence and the device information, the system sends a geolocation data request to the device, causing the device to gather and send the device's current geolocation data to the computing system. A data structure is generated to store data related to the device's current geolocation and sent to the application, which in turn causes the application to grant or deny the authentication request.

Abstract: The present invention provides an improvement of a 4-quadrant clock phase interpolator design to allow independent rotation of the output clocks in steps of 90°. This feature is useful in clock/data recovery where the 90° “jumps” can be used as a coarse control to re-align the data capture clock to achieve any desired data word alignment and/or receive bus clock alignment. The phase interpolator has a switching circuit comprising a single level of switches; a set of four transistor loads; and a set of four current sources operable to be switched by the switching circuit through to any of the set of four transistor loads.
