Abstract: A system and method is disclosed for providing a reverse channel to enable interactive communication between a DBS subscriber and DBS service provider. The addition of an interactive return channel overcomes the problems associated with existing audience measurement systems as well as the problems associated with existing DBS signal security techniques.

Abstract: A viewing and imaging system is provided for use in a screen printer. Light is supplied to the screen and/or the board from a number of independently controller light sources. According to one aspect of the invention, one light source provides substantially collimated light and another light source provides diffuse light. The light sources are controlled by a controller that pulses the light sources in order to provide a stroboscopic image of the board and screen. The duration of the pulses is adjusted to adjust the effective brightness of the light sources. The timing of the pulses are adjusted so that the temporal midpoints of pulses from each of the light sources are coincident.

Abstract: Polymer derivatives based upon polyalkyleneimine backbones having a color stabilizing-effective amount of their reactive amino functionalities substituted by either a carboxylic acid or an amino-protecting group such as urea, are disclosed. Methods for preparing said derivatives are also disclosed. Fiber lubricant compositions comprising said polymer derivatives, and the resistance to yellowing associated with such lubricants are disclosed. Also disclosed are methods for treating fibers using the polymer derivatives.

Abstract: A memory in a computer system includes a visible portion and a hidden portion. The visible portion of the memory is addressable by a processor and the operating system operating within the computer system. Addressability by either the processor or the operating system is excluded to the hidden portion of the memory. The hidden portion of the memory is used for storing data transmitted by either the processor or the operating system. A communications area, located in the visible portion of memory receives requests for data access from either the processor or the operating system. A hidden server which addresses both the visible portion of memory and the hidden portion of memory receives requests for data access from the communications area and initiates data access from the hidden memory.

Abstract: Apparatus is provided for aligning two objects (1,2), such as a board and screen in a screen printer, each having at least one reference mark (6a,7a) on a surface thereof, whereby alignment of the objects is indicated by alignment of corresponding reference marks on the surfaces of the objects. The apparatus comprises support means for supporting the objects in use with the said surfaces facing one another, and imaging means (20), mounted for movement between the said surfaces in use, for acquiring, on a single imaging surface thereof, simultaneous images of respective areas of the surfaces of the objects, which areas contain corresponding reference marks. The apparatus includes control means (4,8) for determining the locations of the reference marks in the images and determining therefrom the extent of misalignment of the objects, and means (3), responsive to the control means, for adjusting the relative positions of the objects to bring the objects into alignment.

Abstract: A three-phase electric motor is partially braked as a result of self-excitation when the power supply is disconnected and a capacitor is connected across one of the windings. The motor is then rapidly brought to a standstill by applying a short-circuit (or connecting a relatively low impedance) across one or both of the other windings, and essential condition being that the short-circuit is initiated within a predetermined range of values of phase angle in a waveform of the self-excitation. Preferred ranges of phase angle are established for selected configurations of mechanical and electronic short-circuiting switches.
