摘要： A method and apparatus for increasing inking resolution in an ink-mosaic recording device. In order to increase the inking resolution in a simple manner, a recording head is periodically deflected transversely to a direction of ejection of the drop of fluid, and the ejection is synchronized with this deflection. Thus a transverse speed component may be superimposed on the drop so that an encountering point on the recording carrier is shiftable. With a same number of transducers and constant transducer spacing, the recording points may be positioned closer to one another.

摘要： In an illustrated transducer construction, electric potential changes applied to the transducer effect piezoelectric movement for causing recording fluid to be ejected through a jet orifice and applied on a recording carrier. In order to increase the maximum drop frequency and in order to improve the drop formation and drop speed, in accordance with the disclosure the linear distance of the connection points of the two ends of each transducer with the orifice plate is smaller than the length between the connection points as measured along the transducer. The transducers are thus mechanically prestressed to assume an arcuate configuration so that, in the rest state, recording fluid is disposed between the transducer and the plate. Given an electric driving pulse the transducers are shortened and conform with the plate in a planar fashion. Immediately after the excitation, each transducer returns to its arcuate initial configuration.

摘要： A mosaic recorder having a plurality of nozzles for ejecting recording liquid droplets on a moving recording medium for punctiform representation of characters and images, each nozzle having a piezoelectric transducer associated therewith and said nozzles being arranged in a recording head adjacent to one another in rows, has an improved nozzle structure wherein the inlet opening of each nozzle is generally oblong in shape and the nozzle tapers to a smaller circular outlet opening from which the recording liquid is ejected. The relatively large size inlet opening increases the ratio of the inlet opening size to the outlet opening size, thereby increasing the ejection speed of the recording liquid droplet. The hydraulic separation between adjacent nozzles is also increased and the mechanical coupling between adjacent transducers is decreased by the oblong configuration of the inlet opening while the spacing between the nozzle outlet openings remains the same.

摘要： A method and a system for jetting droplets of viscous medium, such as solder paste, onto a substrate, such as an electronic circuit board. The volume of the droplets are adjusted by regulating the amount of viscous medium that is fed into a jetting nozzle for subsequent jetting of the viscous medium droplets therefrom. The exit velocity of the jetted droplets is adjusted or maintained substantially constant by regulating the velocity with which the viscous medium is impacted. Furthermore, the rate at which viscous medium is fed, for instance by a feed screw, into the nozzle is adjusted in order to regulate the feeding time required for feeding the viscous medium into the jetting nozzle, for instance in order to maintain a constant feeding time.

摘要： An implantable heart stimulating device has a stimulation pulse generator that emits stimulation pulses at an adjustable stimulation rate, an activity sensor that emits an activity signal in response to detected activity of the patient, and a physiological parameter sensor that generates a physiological sensor signal in response to a detected physiological parameter. The activity and physiological sensor signals are supplied to a control arrangement that sets the stimulation rate for the stimulation pulse generator by executing a stimulation rate algorithm dependent on those signals. In the stimulation rate algorithm, if the physiological signal indicates an emotional stress on the part of the patient, the stimulation rate is increased to an adjustable emotional stress rate level, and if no increase in the activity signal occurs during a predetermined time period following the stimulation rate increase, the stimulation rate is decreased.

摘要： An accelerometer has a cantilever beam supported at one end and having an opposite free end with a longitudinal direction between the supported end and the free end, the beam being formed of a piezoelectric layer and a supporting layer. An inertial, sensing mass is mounted at the free end of the beam, and is located eccentrically relative to the longitudinal direction of the beam. The accelerometer has a primary direction of sensitivity to acceleration forces, and a secondary direction of sensitivity, which is orthogonal to the primary direction and in which the sensitivity is negligible. The secondary direction forms an angle relative to the longitudinal direction of the beam such that a line coinciding with a force proceeding through the center of gravity of the inertial mass, and which is directed in the secondary direction, also intersects the beam.

摘要： In an apparatus for determining the actual status of a piezoelectric sensor in a medical implant, electrical charges generated in the sensor, in response to changes in acceleration and/or gravitational force or other loads acting on the sensor, are continuously detected and the charges are then removed from the sensor, thereby maintaining the voltage across the sensor at a substantial constant zero level. The detected charges, both negative and positive, are integrated, thereby providing a resulting integrated signal representing the actual status of the sensor. The integrated signal is then evaluated for determining the physical activity and/or the posture of a patient in whom the medical implant is implanted.
