Abstract: Pincers for removing residual dental roots by the application of a contrary force on the mandible and maxilla on a pre-fixed screw. It is constructed in such a manner as to enable the strength of the operator to be multiplied and the final movement of the pincers to be reduced. The operator will need to apply minimal force and thus the procedure becomes simple and safe, thereby preserving the underlying bone structure and facilitating implant osseointegration. Likewise the device can be easily sterilized and assembled/dismantled easily because of the small number of moving parts. Further, there is no need for the mouth to be opened so widely, which results in less movement and less trauma caused by excessive opening of the patient's mouth, and it adapts to the irregular profile of support on the dental arch.

The control unit is configured to measure/detect a variation involving increase/decrease of the intensity of ionization current detected, the variation in intensity of ionization current being generated during the change between a first condition, in which the ionization current identifies the ignition state of only the pilot burner, and a second condition, in which the ionization current identifies the simultaneous ignition state of the pilot burner and the main burner so that, by detection of the measurement/variation of ionization current, the effective ignition of the main burner is recognized.

Abstract: A method of controlling a gas powered water heater includes attempting to pick a main gas valve of the main burner using a first pick method. The first pick method includes closing a switch of a valve pick system to couple a capacitor of the valve pick system to the main gas valve for a first length of time to discharge energy stored in the capacitor to the main gas valve, and opening the switch of the valve pick system after the energy stored in the capacitor is discharged to the main gas valve. The controller determines if the main gas valve is open after using the first pick method. When the controller determines the main gas valve is not open, the controller attempts to pick the main gas valve using a second pick method different than the first pick method.

Abstract: A processor for a controller of a water heater is configured to receive water heater control parameters and an output from a sensor indicating a measured temperature of water in the water heater. The processor is also configured to determine whether to enter an anti-stacking control mode or to enter a demand anticipation control mode. In the anti-stacking control mode the processor is configured to initiate a call for heat when the measured temperature reaches a trigger temperature, calculate a burner on delay value and set a second timer with the calculated value, and calculate a reduced activation time. In the demand anticipation control mode the processor is configured to increase the variable offset based on a frequency of the demand anticipation control mode being activated, initiate a call for heat, and control, based on the reduced activation time or the increased offset value, the burner.

Abstract: A method for modulating a valve regulating the flow rate of gas towards a burner is presented. The valve with the associated closure member configured to operate with a predetermined characteristic curve, the flow rate delivered being proportionally related to the strength of a first current signal sent to the modulator such that the flow rate can be modulated, using the proportionality, within a range of modulation between a maximum flow rate and a minimum flow rate. To deliver controlled gas flow rates that are below the minimum flow rate, the modulator is driven with a second PWM voltage signal capable of generating a particular second PWM current signal, to move the closure member of the valve according to the second signal. First and second time intervals correspond to successive durations of high signal and low signal, respectively, the sum being equal to a period of the second signal.
