Abstract: An apparatus includes an accelerometer (24) for providing an analog acceleration signal indicative of crash acceleration. A sigma-delta A/D converter (26) is operatively connected to the accelerometer (24) for providing a pulse-width-modulated gate enable signal (GES) with a value indicative of the acceleration signal. The GES signal is ANDED with a clock signal to produce a pulse-density signal (CNT) indicative of the acceleration signal. A monitoring circuit determines (i) whether at least one pulse-density signal occurs when a gate enable signal is HIGH (FLAG 1), and (ii) whether the pulse-density signal occurs when the gate enable signal is LOW (FLAG 2). Other embodiments test to see if the gate enable signal is either full scale ON (FLAG 3) or full scale OFF (FLAG 4) by using a second crash sensor (64). Timing circuits (302, 316) are used to ensure that the pulse duration of at least one pulse-width modulated gate enable signal is greater than predetermined value within a predetermined time period.

The hardening of the boundary layer is formed such that, due to the hardening, high residual compressive stresses (at least -450 N/mm.sup.2) are produced in an at least approximately 0.5 mm deep boundary zone near the surface such that, even after the cam discs are mounted on the tube, the superimposing residual tensile stresses in the boundary zone, induced by the joining, only partly compensate the original residual compressive stresses, i.e. there are still only residual compressive stresses (at least -150 N/mm.sup.2) in the boundary zone near the surface. Sufficiently high residual compressive stress in the boundary zone are produced by effecting the inductive heating of the cam disc in two stages.

Abstract: Clutches in multi-speed transmission have been initially calibrated in an attempt to determine the point at which the clutch is filled and thus reduce the harshness of engagement of the elements within the clutches during future gear ratio changes in the transmission when being worked under normal conditions. In these earlier attempts at calibrating the clutches, the desired pressure level needed to fill the clutch was either empirically derived or calibrated by incrementally increasing or stepping the pressure level from a minimum value to the required value. In the subject invention, the clutches are calibrated by using a method of calibration that is substantially the same method that is used during normal operating conditions. By using substantially the same method, any effects of "hysteresis" of the associated valving is basically eliminated.

Abstract: A media buffer capable of buffering two lengths of media, is fed a first length of media from an imagesetter at a first speed, and releases the media to a processor at a second speed. An input media sensor senses the media entering the buffer. Drive rollers take up the leading edge of the media at the imagesetter speed. Shortly thereafter a signal from an output media sensor located between the drive rollers and the processor, opens an input door to an input bin and stops the drive rollers. The incoming media continues to be fed by the imagesetter forming a first slack loop within the input bin. The imagesetter signals the buffer that the media has been cut, thereby actuating drive rollers to advance the media at the processor speed to a pair of rollers in the processor. A signal from the processor sensor opens an output door to an output bin. The drive rollers increase speed to transport the first piece of media from the input bin to the output bin thereby forming a second slack loop.

Abstract: A calender employs an open-stack like arrangement with a single vertical beam or support column on each end of the calender. In combination with the support beam, a special swing link is used to support tension loads on the open side of the calender. The nip is thus straddled by structural members between the support column and the link. This combination has the ability to support high linear nip loads, as high as 3,000 PLI or higher.

Thus, the strength of the closed-stack calender is combined with the visibility and ease of access of the open-stack calender by the employment of tension links which replace one of the support columns utilized in a closed-stack calender.
