Abstract: Embodiments of the present disclosure may monitor and adjust a sampling rate of an ADC for converting the power signal to a digital signal, locking onto the phase and frequency of the power signal. This technique may make the sampling process coherent relative to the power signal. Properties of the power signal, such as phase, frequency, and magnitude, may be extracted relative to an idealized power signal.

Abstract: Microwave resonance cavities and associated methods and apparatus are described. In one example, a cavity (100) comprises a first and a second input port (102, 104) for inputting microwave radiation at a first and a second frequency respectively. The microwave radiation at the first frequency may be to excite a sample in the cavity whereas the microwave radiation at the second frequency may be to interrogate a sample in the cavity for analysis. The cavity has dimensions such that it resonates at both the first and the second frequency.

Abstract: Methods, systems, and computer readable media are provided for determining a collaboration status of a user of an electronic messaging system based on user data, including: (i) health data representative of a physiological parameter or mental engagement of the user and (ii) collaboration activity data representative of social collaboration activity of the user, to determine the collaboration status. Historical health data and collaboration activity data may be included in the determination of the collaboration status. In some aspects, the collaboration status may reflect a real-time collaboration status of the user.

Abstract: Some embodiments provide a non-transitory machine-readable medium that stores a program. The program receives from a client device a request for contacts to use to initiate communications for a product. The program further identifies a set of contacts associated with a user of the client device. The program also determines a subset of the set of contacts associated with the user based on data associated with the product. The program further provides the client device the subset of the set of contacts associated with the user as candidates for initiating communications for the product.
