A startup circuit to ensure a bandgap reference circuit reliably starts up or recovers from a noise disturbance is provided. The startup circuit incorporates a pull down resistor to detect the bandgap reference circuit being in a disabled state. The startup circuit creates a positive feedback loop to force the bandgap reference circuit out of a disabled state. Consequently, whenever the power supply for the bandgap reference circuit sags or if bandgap output collapses, the output of the bandgap circuit reliably ramps back up to the expected level.

A bootstrap assist circuit and a startup circuit comprising a voltage controlled switch and a startup ramp voltage generator connected to the voltage controlled switch that will control a high side switch, a dimming interface or an enable/disable input function.

Data representative of a train consist (the train consist comprising a plurality of locomotives and a plurality of cars) and data representative of a route for the train consist can be processed by a processor to automatically determine which locomotives in the train consist should be powered on and which locomotives in the train consist should be shut down for each segment of the route. The processor can make these determinations based on an analysis of the train consist data and the route data with respect to a plurality of considerations that affect train efficiency. Recommendations for locomotive startups and shutdowns in accordance with such automated determinations can then be presented to the train crew for the crew to use during train operations. It is believed that when train crews are in compliance with such recommendations, significant improvements in efficiency, particularly with respect to fuel consumption, can be achieved.

The invention provides methods and compositions for increasing the strengthening effect of a starch coating on paper. The method involves contacting the starch with a synthetic polymer before the starch is cooked. This changes how the starch gelatinizes and how the polymer gets distributed on the paper resulting in greater paper surface strength.

In a starter, an output shaft is supported by a main tube body according to a direct contacting structure that outer surfaces other than a male helical spline and inner surfaces other than a female helical spline of a pinion tube contact directly. Thereby, the output shaft can be supported by the pinion tube without other parts. As a result, a clearance that occurs in a radial direction can be limited to a clearance in the radial direction formed between an outer surfaces of the output shaft and an inner surfaces of the pinion tube regarding a support of the output shaft by the pinion tube, and since an inclination of the pinion tube and the pinion relative to the output shaft can be suppressed, a life improvement effect of the starter can be enhanced.

The method calibrates a radius value of the selected probe head, and calibrates the deviation between the center point of the selected probe head and the focus of the camera lens. The method further generates a star probe model of the star probe according to the probe configuration information and the probe calibration information, and displays the star probe model of the star probe on a display device of the image measuring machine.

The transducer absorbs the electrical power of the fuel cell, in which at least one reactant supply of the fuel cell was interrupted, where the interrupted reactant supply is resumed from a restart signal, and where a fuel cell voltage is prescribed and then regulated by the transducer. The prescribed fuel cell voltage is prescribed in a way that an electrical unloaded fuel cell supplied with reactants will exceed the prescribed fuel cell voltage in every case, and the current of the transducer necessary for maintaining the prescribed fuel cell voltage is measured, where the normal operation is released as of a prescribed current necessary to that effect.

The refrigeration installation comprises a refrigerant vessel for receiving a refrigerant which can be used for cooling a component of the container treatment installation, and a control device for controlling an amount of the refrigerant in the refrigerant vessel such that, after operation of the refrigeration installation, only a predetermined residual amount of refrigerant remains in the refrigerant vessel for the transport of the refrigerant installation, and after the transport of the refrigeration installation, the predetermined residual amount is filled up with a predetermined replenishment amount of refrigerant.

A novel process for activating available compressors in multiple compressor air conditioning systems, using an Optimum Stage-Up Process. This process is programmed into a controller as an algorithm, to provide a process for fast compressor start. This process shortens the time to initiate operation of compressors in a multi-compressor air conditioning system required to meet the demand call under any load condition, and hence shortens the time required for the actual sensed interior region air temperature to reach the interior region temperature set point. The Optimum Stage-up Algorithm estimates the number of compressor stages or steps that must be initiated, based on sensed or measured values, to meet the demand at any load condition. These measured values include the sensed temperature of the interior region being cooled, which is compared to the temperature set point of this interior region as well as measured mixed air temperature and supply air temperature.
