Abstract: A system and methods to configure, track and provide device data for clients is disclosed. The system configures a device to interact according to client specified settings. The system also tracks relevant data from a service provider interaction with the client. The system is configured to provide the tracked data to a third party upon a validated request. For example, the system may store and provide the tracked data in the cloud, through a network.

Abstract: A device is provided for measuring dielectric constant and conductance of a material such as massecuite, the device including a pair of electrodes which are switchably connected to a tank circuit which includes a variable frequency oscillator operating at radio frequencies, and two reference frequencies are measured with the electrodes disconnected from the oscillator and two measurement frequencies with the electrodes coupled to the oscillator tank circuit, the differences between the reference and measurement frequencies being used to compute the inductance and dielectric constant or composition of the material. The frequency is modified by not more than about 10 MHz and may be achieved either by switchably introducing additional inductance or capacitance into the tank circuit to modify its frequency or by having the electrodes switchable between a pair or oscillators operating at known radio frequencies.

Abstract: The invention provides an apparatus for controlling both the supersaturation of the mother liquor and the crystal content of massecuite by measuring di-electric constant and electrical conductivity at radio frequencies by means of a probe which is included in a circuit which may be tuned to a fixed setting or may be variably tuned, the combined impedance is measured as a function of the tuning and the measurements are compared with predetermined desired values. By suitable combination of the two signals, measurement of crystal content and mother liquor supersaturation can be controlled.
