Abstract: An improved instrument for measuring low indicated air speed greatly reduces variation with one or more of time, temperature, and ambient pressure change. This is accomplished by periodically re-zeroing the transducer using only a single electronically controlled valve. Re-zeroing may be initiated in response to a change in the internal temperature of the transducer.

Abstract: An image forming apparatus includes an image bearer including a first image portion to bear a first toner image, a second image portion to bear a second toner image, and a non-image portion to bear an adjustment pattern. A transferor forms a transfer nip with the image bearer. A controller controls the power source to output an image bias as a transfer bias to transfer the first toner image and the second toner image onto a first recording medium and a second recording medium, respectively, in the transfer nip when the first image portion and the second image portion pass through the transfer nip and output a non-image bias as the transfer bias when the non-image portion passes through the transfer nip. The controller performs a constant current control on the image bias and performs a constant voltage control when the image bias switches to the non-image bias.

Abstract: A method for determining the mass of a body is described. The method comprises the application and measurement of a first motive force to the body to move the body in a first state of motion. The acceleration of the body is also measured at this time. This methodology is repeated for a second state of motion. The measured motive forces and accelerations are then used to calculate the mass, and hence the weight of the body. An accelerometer may be employed to measure the accelerations. The methods may be adapted so as to correct for the angle ? of the ground across which the body is moved and or the tilt angle ? of the accelerometer relative to the ground. The methods may employ a novel surface angle measuring device that does not require contact with the ground and which does not require the body to be stationary.
