  • Patent number: 10844035
    Abstract: The present disclosure relates to a cannabidiol compound and compositions thereof and processes for preparing the compound and compositions. The processes include an acid-catalyzed reaction of a suitably selected and substituted di-bromo-olivetol or derivative thereof with a suitably selected and substituted cyclic alkene to produce a dibromo-cannabidiol compound or derivative thereof. The dibromo-cannabidiol compound or derivative thereof can be produced in high yield, high stereospecificity, or both. It can then be converted under reducing conditions to a cannabidiol compound or derivatives thereof.

  • Patent number: 10256065
    Abstract: A relay control circuit for use with a relay having a coil voltage input. The relay control circuit includes a first input to receive a first voltage capable of energizing the relay from a de-energized state, a second input to receive a second voltage, less than the first voltage, that is capable of maintaining the relay in an energized state, and means, responsive to a relay control signal having one of a first state and a second state, for switchably coupling the coil voltage input to the first input for a period of time sufficient to energize the relay in response to the relay control signal having the first state, and for switchably coupling the coil voltage input to the second input in response to expiration of the period of time.

  • Patent number: 9787087
    Abstract: An electronic device including first and second line inputs, first and second device inputs, a filter circuit, and a switching circuit. The filter circuit has a first input electrically coupled to the first line input, a second input electrically coupled to the second line input, a first output electrically coupled to the first device input, a second output, and at least one capacitor electrically coupling at least one of the first input to the second input or the first output to the second output. The switching circuit has a control input to receive a control signal, and electrically couples the second output to the second device input in response to the control signal having the first state and electrically couples the second output to one of the first input and the first output through a resistor in response to the control signal having the second state.

  • Patent number: 7944182
    Abstract: An uninterruptible power supply (UPS) having an adjustable battery charger that generates a charger current, and a controller, coupled to the adjustable battery charger, that receives a signal representative of a system constraint and provides a reference, based on the signal, to the adjustable battery charger to control an amplitude of the charger current supplied by the adjustable battery charger based on the system constraint. The system constraint may include, for example, a maximum input current to the UPS, maximum charging current of the battery cell, and maximum and/or minimum charger current values.
