Abstract: A crystal-free wireless device includes a frequency calibration module and a local radio frequency (RF) oscillator having a first frequency and configured to communicate with the frequency calibration module. The crystal-free wireless device also includes a relaxation ring oscillator configured to communicate with the frequency calibration module. The relaxation ring oscillator is further configured to receive a calibration signal or periodic radio frequency packets from a wireless network and provide a reference signal to the frequency calibration module. The relaxation ring oscillator is a crystal-free oscillator. The frequency calibration module is configured to generate a calibration signal that is fed back through a Frequency Locked Loop (FLL) to the local RF oscillator to calibrate the local RF oscillator. The calibrated local RF oscillator is configured to generate a clock signal.

Abstract: In one embodiment, a server computer may receive, from a client device, a request to download an application, wherein the client device is logged-in to a session associated with a user account in a communications system. In response to the request, a downloader module executable file may be appended with the login information and the authentication information. The server computer may transmit the downloader module executable file to the client device. In response to a second request (from the downloader module executable file), the server computer may transmit the installer file to the client device.

Abstract: Systems, methods, and non-transitory computer-readable media can determine a user request to recover control of an account for accessing an account provider system. A recovery token that is associated with the account can be obtained. A signature for at least a portion of the recovery token can be generated. Metadata information associated with the account provider system can be obtained. The signed recovery token can be provided to the account provider system based at least in part on the metadata information, wherein the account provider system is configured to provide control of the account to the user upon validating the signed recovery token.

Abstract: A cloud computing monitoring system has an alert capturing system and a message transfer system that provides performance tracking and alert management to a local monitoring system. The alert capturing system may operate as part of a managed code framework and may capture and route alerts that may be transmitted to an operating system, as well as application exceptions and debugging information. A message queuing system may transmit the alerts to a local monitoring system, which may have a connector that subscribes to the cloud system's message queuing system.

Abstract: A compact portable transport unit for shipping hyperpolarized noble gases and shielding same from electromagnetic interference and/or external magnetic fields includes a means for shifting the resonance frequency of the hyperpolarized gas outside the bandwidth of typical frequencies associated with prevalent time-dependent fields produced by electrical sources. Preferably the transport unit includes a magnetic holding field which is generated from a solenoid in the transport unit. The solenoid includes a plurality of coil segments and is sized and configured to receive the gas chamber of a container. The gas container is configured with a valve, a spherical body, and an extending capillary stem between the valve and the body. The gas container or hyperpolarized product container can also be formed as a resilient bag.

Abstract: A system, method, and computer program products and associated apparatus, to monitor and determine the polarization level of a quantity of hyperpolarized gas during transport. A portable device is configured to transmit an excitation pulse and analyze a response signal in transit to provide a polarization level corresponding to the hyperpolarized gas. Preferably, the monitoring system can provide magnetic field fluctuation feedback to the transport unit and adjust operating current to a solenoid. The system also can compensate for NMR frequency shifts that may appear in the measured response signal to provide a more accurate polarization level or “real” T1 for the hyperpolarized gas.
