Abstract: A computer with a pipelined processor and code breakpoints for performing software debug operations includes prefetch and decode stages, debug address registers for storing code breakpoints representing addresses of preselected instructions, and two digital comparators. During the instruction prefetch phase of operation, the first comparator compares the 29 most significant bits ?31:3! of the 32-bit prefetch instruction address against the code breakpoints stored in the debug address registers and produces a 1-bit signal indicating whether such comparison results in a positive match. Subsequently, during the decode phase of operation, the second comparator compares the three least significant bits ?2:0! of the 32-bit prefetch instruction address and produces a 1-bit signal indicating whether such comparison results in a positive match.

Abstract: A method of sealing off a vaporization chamber provided in a soleplate of a steam iron by means of a cover is described. The vaporization chamber has an outer wall which has an upper edge remote from the bottom surface of the soleplate and having an upwardly opening continuous recess or groove provided therein. The method comprises placing the cover over the vaporization chamber in contact with the upper edge of the outer wall and applying high pressure to the cover, the cover material being forced into the recess to sealingly connect the cover to the soleplate before the pressure is released. There is no need for any additional sealing materials between the chamber and the cover and no need to screw or rivet the cover onto the soleplate.

Abstract: An electrically heated steam iron has a soleplate in which are arranged an electrical heating element and a vaporization chamber, and a soleplate liner which consists of a different material from the soleplate and which is fixed thereto.

Abstract: An implantable pacemaker having circuit means for indicating, by pulse width modulation of the delivered pacing pulses, the programmable control states which control the selected pacemaker operating perameters. The circuitry includes a parallel to serial shift register adapted to receive the control states from a pacer circuit and to generate a serial multiple bit word when the pacemaker is switched to a magnetic mode. The shift register is clocked by stimulus timing signals, and the multiple bit word drives a one shot generator, the output of which is combined with the timing pulses to produce pulse width modulated pacing pulses.

Abstract: The field of this invention is fluid flow control through large conduits. In particular, this invention is contemplated for use in a combined cycle power plant wherein gas turbine exhaust gas is either sent through a heat recovery steam generator (HRSG) or diverted to the atmosphere. The invention is a damper and frame assembly believed to be well suited to the purpose of channeling the hot exhaust gas within the context of a combined cycle power plant either as an isolation damper to the HRSG or a bypass damper to the exhaust stack. One key consideration is the thermal relationship between the damper blade and its adjacent frame and provision is made to provide a damper blade that will not warp and a frame wherein thermal growth and distortion are limited.

Abstract: A programmable digital atrio-ventricular pacer is provided whereby a single programming circuit is utilized for providing program control signals for control of separate ventricular and atrial pacing circuits. The atrial stimulus circuitry is controlled by a multiple bit control signal to cause derivation of atrial timing signals from the same clock signal as used for deriving ventricular stimulus pulses. A programmable digital multiplier is employed in combination with a counter to set the atrial escape interval independent of the timing of the ventricular stimulus pulses.

Abstract: A circuit for indicating at a remote location the control states of a fully implantable heart pacer includes a parallel to serial converter which receives the control states from a register which controls the parameters of the associated pacer. When the pacer is switched to an asynchronous or to a magnetic mode, the data is shifted through the parallel to serial converter. A delay is added between pulses when a particular logic state appears, and no delay is added if the complement of that logic state appears. The parameters can therefore be determined externally by observing the successive periods between stimulation pulses in the asynchronous or magnetic mode of the pacer.

A command parameter control is used for programmably controlling parameters of the pacer operation as well as of the tachycardia recognition and response to same. Upon recognition of tachycardia, a series of stimulus pulses of predetermined rate and number are delivered, the tachycardia breakup pulses being generated and delivered through an output circuit utilized commonly with the demand pacer circuitry.

Abstract: A heart pacer employing a digital parameter controlling circuit is controlled by data received from an external source, the data preferably being in the form of magnetic pulses of width corresponding to the desired logic state of the parameter controlling signal. The externally transmitted signal which is received by the pacer comprises both parameter data for controlling selected pacer parameter operation and access data which is processed by the pacer for determining whether the parameter data is accepted for control purposes. The access and parameter data components of the externally generated signal are intermixed so that when receipt of the signal is enabled by the pacer, proper receipt of the parameter data is also ensured.

Abstract: A digital cardiac pacer has an asynchronous interval counter to count clock pulses to establish a stimulation interval at the end of which it produces a pulse for initiating a stimulation pulse. A control counter to which amplified naturally occurring heat pulses or stimulation pulses are applied controls the delivery of a resetting pulse to the asynchronous interval counter to reinitiate its count. If the stimulation, heart, or an interference pulse is detected during the count of a "refractory period," the control counter is reset and the refractory period is extended. If another stimulation, heart, or interference, pulse is detected during the extended refractory period, no resetting pulse is delivered, and the asynchronous interval counter continues its normal count. If during the period of time following the extended refractory period a stimulation, heart, or interference pulse is received, the control counter produces a resetting pulse to reset the asynchronous interval counter.
