  Bias drive   (Site not responding. Last check: 2007-10-11)
A concept from NASA's Breakthrough Propulsion Physics Program, the bias drive is a pitch drive that functions by altering the gravitational constant G in front of and behind the craft.
One problem with this concept is that it would create a singularity in the field's gradient located inside the vehicle.

Some examples include the Diametric drive, the Pitch drive, the Bias drive, the Alcubierre drive, the Disjunction drive, and the Differential sail.
The pitch drive is a diametric drive which uses the principle of a disjoint field (as in the disjunction drive) to eliminate the need for the field to be generated on the spacecraft itself.
The bias drive is a pitch drive that functions by altering the gravitational constant G in front of and behind the craft.

 Current control loop bias calibration by integration - Patent 7038417
The second reel assembly is often permanently mounted in the tape drive and is connected to a second drive motor.
Ascertaining through integration a bias calibration level for a current control loop of a driver motor of a tape drive is disclosed.
As the bias signal is stepped down, at some point a voltage difference will appear at the input of the integrator 26 such that the voltage at the negative input is greater than the voltage at the positive input.

As a result, by virtue of the bias of spring 10, the coupling 16 moves inside the drive element 12, the syringe 4 is driven away from the opening 6 and the needle 8 is retracted within the opening 6.
The drive element continues to apply a force to the drive coupling by virtue of the frictional resistance such that the frictional surfaces slip, the drive coupling reduces in length and the drive element reaches the required position to trigger the return mechanism.
The drive coupling may include a rack and a pinion gear wherein one of the rack and the pinion gear is movable by the drive element and the other of the rack and the pinion is operable to move the dispensing piston.

 VHF/UHF Long Yagi Workshop
But for SSB modulation, the delayed turn-on at low drive levels is disastrous: it means that all the low-level parts of the modulation are severely distorted and the amplifier only delivers RF power in bursts on speech peaks.
It is very important that the bias supply maintains a fairly constant output voltage, even at maximum current demand; if it fails to do that, the RF drive will bias the transistor back towards Class C, causing heavy splatter on speech peaks.
Bias regulation totally fails when peaks of RF drive create a heavy demand for base current, so this circuit is a real splatter-generator.

 Torsen differential white paper
That is, even though the bias ratio remains relatively constant, a proportional division of a lower magnitude of torque being conveyed by the differential results in a smaller torque difference between drive axles.
The bias ratio characteristic also remains substantially constant over a wide range of torque conveyed by the differential, and is not sensitive to changes in ambient temperature or conditions of vehicle use.
The engine torque is transferred to the drive axles through (a) the differential housing which supports the ring gear and (b) the Invex gearing which is carried within the housing and interconnects the drive axles for equal but opposite directions of relative rotation with respect to the housing.

 Things You Should Know About Farm Tires   (Site not responding. Last check: 2007-10-11)
The load and/or pressure capacity of a tire is shown in the ply rating (bias tires), the star marking (conventional radial tires), or the load index (metric radials).
This is because the average pressure under a tire is a little higher (about 1 to 2 psi for a radial and 2 to 3 psi for a bias) than the inflation pressure in the tire.
While an underinflated drive tire may pull better in some soil conditions, this is not generally true and not worth the high risk of tire damage incurred.

 January 7, 1997   (Site not responding. Last check: 2007-10-11)
The Diametric Drive works with field sources, the Pitch Drive with the field itself, the Bias Drive with the properties of the space that contain the field, and the Disjunction Drive with the properties of matter that create and react to a field.
To entertain the possibility of a Pitch Drive, a localized gradient in the scalar gravitational potential is superimposed across the symmetric gravitational potential already present from the vehicle’s mass.
Simply put, a space drive requires some controllable and sustainable means to create asymmetric forces on the vehicle without expelling a reaction mass, and some means to satisfy conservation laws in the process.

 DOES BIAS BUY US ANYTHING ANYMORE?
Drive is simply the gain of the tube, or the factor by which the driving voltage is amplified to the anode and thence on to the imaging surface.
With a purely linear circuit, setting bias (also known as offset or cut) and then tweaking drive is a pretty straightforward matter.
That is the reason why so few manufacturers of plasma display panels include a drive setting on their products and why adjusting those models that do have such a setting becomes a game of rock 'n' roll.

 BioMech Motor Bridges
This circuit is useful for pulse driving a motor in one direction from, for example, CMOS control outputs in solar-style designs where a high-impedance off-state is critical to save power.
Exact bias equations vary depending on transistors used, but even high-power drive transistors can be controlled through small bias transistors, typically 2N3904s or 2N3906s.
And of course, the bias transistors can also be mismatched to make an alternate input polarity driver, fine for straight push-pull from a single control source if desired.

 Spacecraft propulsion -- Facts, Info, and Encyclopedia article   (Site not responding. Last check: 2007-10-11)
Drives such as VASIMR, and to a lesser extent other Ion thrusters have exhaust velocities that can be enormously higher than this ideal, and thus end up powersource limited and give very low thrust.
It turns out that to a reasonable approximation, for these drives, that fuel use, energetic efficiency and thrust are all inversely proportional to exhaust velocity.
Their very high exhaust velocity means they require huge amounts of energy and provide low thrust, but use hardly any fuel.

In the case of the Alcubierre warp drive, this moving section of spacetime is created by expanding spacetime behind the ship (analogous to where the sidewalk emerges from underneath the floor), and by contracting spacetime in front of the ship (analogous to where the sidewalk goes back into the floor).
Hypothetical Pitch Drive: This concept entertains the possibility that somehow a localized slope in scalar potential is induced across the vehicle which causes forces on the vehicle.
Hypothetical Bias Drive: This concept entertains the possibility that the vehicle alters the properties of space itself, such as the gravitational constant, G, to create a local propulsive gradient.

 NASA - Ideas Based On What We’d Like To Achieve
A "space drive" can be defined as an idealized form of propulsion where the fundamental properties of matter and spacetime are used to create propulsive forces anywhere in space without having to carry and expel a reaction mass.
A variety of hypothetical space drives were created and analyzed by Millis to identify the specific problems that have to be solved to make such schemes plausible.
Before any of these space drives can become reality, a method must be discovered where a vehicle can create and control an external asymmetric force on itself without expelling a reaction mass and the method must satisfy conservation laws in the process.

 Computerize Your BBQ Experience: PID Loop
The first element of the control loop to understand is the proportional drive, which simply computes a drive value as a factor times the error.
The problem with using only proportional control is that it produces zero drive for zero error—when the measured temperature is equal to the set point temperature.
You can fix that with a bias drive component (the BIAS term in the code above, along with the bias introduced by making 127 equivalent to zero drive in the conversion from drive to PWM), but it's subject to error.

Because the ion drive's needs much less fuel, the total launched mass is usually lower, which typically results in lower overall cost.
This comes to an exhaust velocity of about 2/3 of the delta-v (see also the energy computed from the rocket equation).
For changing the orientation of a satellite or other space vehicle, conservation of angular momentum does not pose a similar constraint.
