Abstract: Systems and methods analyze biopotential morphologies in myocardial tissue by comparing a template of a cardiac event of known diagnosis to one or more samples of a paced cardiac event. The systems and methods generate an output based upon the comparison. The comparison yields an output, which indicates how alike the input sample is to the input template. The output can be used by the physician, for example, to aid in the location of sites that are potentially appropriate for ablation. The systems and methods employing different pacing and/or comparative techniques to provide multiple outputs. The pacing techniques that the systems and methods employ can comprise entrainment pacing or pace mapping. Various alternative comparison techniques include matched filtering, cross correlation, norm of the difference, and symmetry matching.

Abstract: The system and methods obtain a set of multiple data samples and derive an average of the data samples in the set (SET.sub.AVE). The systems and methods derive a standard deviation for the data samples in the set (SET.sub.STD). The systems and methods compare each of the data samples to SET.sub.STD and either reject the data sample, if the absolute difference between the data sample is greater than or equal to k * SET.sub.STD, where k is a selected value greater than zero, or retain the data sample, if the absolute difference between the data sample is less than k * SET.sub.STD. The systems and methods repeat the foregoing steps until the absolute difference between every data sample remaining in the set is less than k * SET.sub.STD. The systems and methods then derive a filtered average for the set FSET.sub.AVG, where FSET.sub.AVE is the SET.sub.AVG for the data set in which the absolute difference between every data sample remaining in the set is less than k * SET.sub.STD.

Abstract: A journal bearing is lubricated with a disk on the shaft which sweeps through oil in a sump for picking up oil and transporting it upwardly in the direction of rotation of the disk to above an oil inlet for a bearing where it is scraped off the disk and caused to flow into the bearing. After a segment of a disk emerges from the oil sump, the disk enters a shroud which has a channel-shaped cross-section and whose back wall at least is curved with a decreasing radius as it extends away from the sump toward the scraper. The shroud captures the oil which would otherwise be spun off of the disk at high speeds so the maximum quantity of oil is retained on the disk when it reaches the scraper. A new scraper design is also disclosed.

Abstract: Analog or digital systems and methods filter an artifact from a composite signal, which comprises sample values arranged with respect to time. The systems and methods select sets of WL sample values in time-sequence along the composite signal and arrange the WL sample values of each set into ordered positions following a predetermined permutation. The systems and methods select one of the ordered positions, z, within each permutation. The systems and methods generate a filter output comprising the sample values occupying the ordered position, z, of each permutation in time-sequence with the composite signal. The systems and methods remove artifacts from signals derived from a biological event; for example, electrograms, electrocardiograms, electroencephalograms, electrogastrograms, electromyograms, and respiratory signals.

Abstract: A rack for supporting frozen pizzas includes a structure having top, bottom, side and rear structural members with a frontal opening for insertion therein of horizontally oriented frozen pizzas. A plurality of vertically stacked supporting members are aligned in pairs and oriented parallel to the side walls of the structure, the members forming shelves providing surfaces for storage of pizzas in the rack. The top, bottom, side and rear walls may each be formed from a series of continuous horizontal members such as coated metal wire. The front members of the rack are spaced apart from each other at a wider distance sufficient to enable passage therebetween of a horizontally oriented frozen pizza than the side members, which are each spaced from each other a lesser distance, thereby forming members for supporting the frozen pizzas.

Abstract: Systems and methods evaluate electrical contact between the myocardium and one or more electrodes inside the heart. The systems and methods electrically sense electrical contact between the myocardium and electrodes and generate unitary contact-indicating outputs indicating the presence or absence of electrical contact between the myocardium and each particular electrode. The systems and methods also correlate the electrode-specific unitary outputs to generate a compound contact-indicating output. The compound output represents the aggregate of the electrical contact between the myocardium and multiple electrodes on a multiple electrode array.

Abstract: Bottles to be cleaned are fed in succession to an infeed starwheel from which they are transferred to a rotor on which there are circumferentially spaced apart cam operated bottle inverting devices that grip the bottles and invert them with their mouths over a nozzle that injects cleaning fluid into them. The gripping devices have on them gripper fingers which are V-shaped and are molded, respectively, of a resilient and deflectable synthetic resin such as a polyamide. There is an upper gripper having finger tips spaced apart to engage the neck of a bottle and a lower gripper having finger tips or the like that grip or support the cylindrical body of the bottle.

Abstract: Systems and methods use an array of multiple electrodes supported for operative association with a region of heart tissue, in tandem with a roving second electrode supported for movement relative to the multiple electrode means for operative association with selected, different regions of endocardial tissue within the heart. An analog or digital processing element conditions one of the multiple electrodes and the roving electrode to emit a pacing signal while the other one of the multiple electrodes and the roving electrode records paced electrograms occurring as a result of the pacing signal. A processing element and method input a template of a cardiac event of known diagnosis sensed using the array of multiple electrodes. The processing element and method inputs a sample of a cardiac event acquired by pacing from at least one roving electrode and sensed with the array of multiple electrodes.

Abstract: In a rotary switch, a manually rotatable shaft turns a disk which has a plurality of riser cam segments on one of its faces. Stepwise rotation of the disk causes the cam segments to press down on flat spring contacts arranged in the switch to put the tip of one of the contacts at a time into contact with a stationary electrical contact bar that is coated with a noble metal. The spring contacts are configured such that when pressed by a cam the tips are caused to make contact with the stationary contact bar and then slide longitudinally so as the tip will pick up some of the noble metal coating from the contact bar. The tips are shaped with a traverse curve intersecting a longitudinal groove to thereby produce two points that make high unit stress contact with the stationary contact bar.

Abstract: Bottles made of transparent plastic material or glass are subjected to at least one stationary examination device and further for detecting impurities or damage to the bottom, side wall or mouth regions of vessels. To be able to detect defects which may cause the bottles to leak, and which cannot be detected reliably by optoelectronic devices, the vessels are inspected additionally using a leak test by developing pressures.

Abstract: An immersion probe for determination of the concentration of a gas dissolved in molten metal includes a probe body in the form of an elongated hermetically sealed housing. The body has a first end adapted to be connected to a gas inlet and a gas outlet, which first end may be hermetically sealed by a temporary sealing means. The body has a second end adapted to be immersed in molten metal, the second end is spaced from and in fluid flow communication with the first end and has a gas-permeable, liquid metal-impervious plug. The second end and the plug are hermetically sealed by a molten metal-soluble cap until melted during immersion into molten metal. An inert, dry carrier gas such as nitrogen or argon may be sealed within the probe body. A metal sleeve around the probe body, preferably of a composition fusible in and compatible with a molten metal being monitored may be used to provide a gas impermeable seal for the probe body.

Abstract: A sign or menu board has a pair of parallel vertical side rails with opposite end portions of upper and lower cross rails joined to the upper and lower end portions of the side rails to form a carrier frame. Each side rail has a track coextensive with its length. Grid modules make up modular grid units. Each unit, which may contain only one module, is comprised of cross bars that are joined at their opposite ends by tie-bars which together with the cross bars define a window opening. The cross bars are provided with lengthwise grooves for slidably accepting an information strip between them. The grid units slide into the carrier frame along the tracks and are constructed such that the information strips can be slid into or out of a grid without withdrawing the grid from the carrier frame. Pictorial assembly retainer bars are also constructed for sliding into the frame on the side rails.

Abstract: In a rotary switch, a manually rotatable shaft turns a disk which has a plurality of riser cam segments on one of its face. Stepwise rotation of the disk causes the cam segments to press down on flat spring contacts arranged in the switch to put the tip of one of the contacts at a time into electric contact with a stationary electrical contact that is connected to a source of electric potential or, in the alternative, to relieve one of the contacts from being pressed onto the stationary contact. An index wheel mounts to the shaft and has equiangularly spaced grooves. A plastic spring having parallel legs is mounted on the base of the switch. The legs have convex detents which register in successive grooves as the rotor is indexed rotationally in a stepwise fashion. The radius of the detents is greater than the radius of the grooves between the teeth of the index wheel. The legs of the spring are prohibited from moving longitudinally and tension is maintained in the spring legs at all times.
