Aspects of the current subject matter are directed to transitioning a vaporizer device between different modes of operation including an active mode, a standby mode, and a deep standby mode. The vaporizer device may include a pressure sensor to measure a first pressure in an air flow path, and an ambient pressure sensor to measure a second pressure corresponding to an atmospheric pressure. The transition between different modes of operation may change the sampling frequency and/or resolution of the pressure sensor and/or the ambient pressure sensor such that sampling occurs at a higher frequency and/or resolution when the vaporizer device is in an active mode. Additionally, a comparison of the pressure in the air flow path with the ambient pressure after a heating element is activated may serve as a verification by the vaporizer device that a user is drawing on the vaporizer device.

A method for the control of a ram movement and ram forces of multi-point servo hybrid presses, where the positions, speeds and forces to drive the ram can be controlled independently of each other by the servo motor, which is assigned to each pressure point or each group of pressure points, for the main drive for the ram movement in the main function and the hydraulic pressure cushions, which are separately assigned to each pressure point of the ram, in an auxiliary function, to influence process-induced position and force settings of the ram in a combinatory interaction to achieve an active control of draw depth and tilt.

An article of footwear with a dynamic support system that controls arrays of tiles in the upper of the footwear to adjust the level of support provided in different regions of the upper. Sensors in the sole of the footwear, in the upper of the footwear and/or in an article worn by the wearer of the footwear measure the level of stress or other characteristics and provide input to one or more microprocessors that control motors located in the sole or in the upper of the footwear. When the motors are activated, they may compress or loosen arrays of tiles to adjust the stiffness of the upper in one or more regions of the upper.

A method for controlling a semiconductor manufacturing facility includes measuring output change amounts of differential pressure sensors in the facility when pressure conditions change by a number of fans. The fans are then classified into different groups and subgroups and control sequences of the subgroups are determined based on the change amounts. Difference values are then calculated, and a control signal is generated to adjust the rotation speed of the fans.

The press wheel has instrumentation associated therewith detecting a rolling of the wheel over a planted set. A computing device is connected to the instrumentation and to the speed monitoring device of the planter. The computing device determines spacings between planted sets. The data obtained is real-time data and is readily available to the operator of the planter so that the speed of the planter can be adjusted on the fly to maintain an ideal set spacing. The press wheel has a soft, smooth, flexible and stretchable rolling surface capable of deforming over a planted set and detecting an imprint of the planted set in the surface thereof, without damaging the planted set. A contact signature of the rolling of the press wheel over a planted set shows that the rolling on of the press wheel over a planted set is as smooth as the rolling away from the planted set.
