    • The present invention provides a short circuit detection system and method for determining a short circuit in a print system. The short circuit detection system includes a parameter sensing circuit in the print system, a parameter usage estimator, and a comparator. The parameter sensing circuit provides a sensed measurement of a predetermined parameter across the sensing unit. The parameter usage estimator is coupled to receive nozzle firing data and a desired unit parameter, and is used for determining an estimated parameter usage value. The comparator is coupled to receive the sensed measurement of the predetermined parameter and the estimated parameter usage value. The comparator determines if the sensed measurement of the predetermined parameter is greater than the estimated parameter usage value. If the sensed measurement of the predetermined parameter is greater than the estimated parameter usage value, the comparator outputs a signal indicating a short circuit condition.
    • 本发明提供一种用于确定打印系统中的短路的短路检测系统和方法。 短路检测系统包括打印系统中的参数检测电路,参数使用估计器和比较器。 参数感测电路提供感测单元上的预定参数的感测测量。 参数使用估计器被耦合以接收喷嘴点火数据和期望的单位参数,并且用于确定估计的参数使用值。 比较器被耦合以接收所检测的预定参数的测量值和估计的参数使用值。 比较器确定感测到的预定参数的测量是否大于估计的参数使用值。 如果感测到的预定参数的测量值大于估计的参数使用值,则比较器输出指示短路状态的信号。

    • A compensation circuit (14) for a ring oscillator (12) having an odd plurality of series-connected CMOS inverter stages includes first and second P-channel transistors and a resistor. The first transistor (32) has a source coupled to VDD and a gate coupled to ground. The resistor (34) is coupled between the drain of the first transistor and ground. The second transistor (36) has a source coupled to VDD, a gate coupled to the drain of the first transistor, and a drain coupled to a supply node of each of the inverter stages of the ring oscillator for providing a supply voltage that is compensated with respect to voltage, temperature, and semiconductor processing variables. In operation, the conductivity of the first transistor inversely controls the conductivity of the second transistor that supplies a compensated power to the inverter stages. The compensated power controls the conductivity of the transistors in the ring oscillator and the corresponding frequency of oscillation.

    • A tire building drum is described as having, a plurality of radially movable bead lock segments at each end of the drum for holding the tire bead rings during the turn-up operation, a pair of turn-up bladders, and a pair of carriers which work in conjunction with the bead lock segments and turn-up bladders to tension the ply endings of the unvulcanized carcass ply or plies as the ply endings are turned up and reversely wrapped around the tire bead rings to anchor the rings to the unvulcanized tire carcass for further processing.The carriers span the bead seats of the bead lock segments and snugly fit around the adjacent turn-up bladders, so that the bead lock segments, upon radial expansion, pull against and distort the shape of the bladders which react to regain their shape and/or position by pushing back against the carriers to tension the carriers which are in contact with the ply endings and which tension the ply endings during turn-up to eliminate, adjacent the tire bead rings, the formation of voids which entrap air and adversely affect the adhesion between the tire bead rings and surrounding rubber material. A lubricant is provided between the contacting surfaces of the carriers and turn-up bladders to permit relative, unimpeded movement between these two components.
