Abstract:
The efficiency of water disinfection can be significantly increased by supplying the ozone in combination with oxygen (16) to an inlet of a cavitation pump (14). The ozone and the oxygen (16) are turned into ultra-fine bubbles (22) via cavitation action within the pump (14), facilitating the dissolution of the oxygen and ozone within the water (11). The water (11) mixed with the oxygen and the ozone (16) is supplied to a line atomizer (20), where the dissolution of the ozone within the mixture is completed. The combined use of the cavitation pump (14) and the line atomizer (20) can lead to a substantially complete dissolution of the supplied ozone within water (11) that needs to be disinfected, allowing to achieve the concentration of ozone necessary for disinfection. The system (10) and method (30) described are highly scalable and suitable for water purification at water purification plants of various sizes.
Abstract:
Physiological monitoring can be provided through a syncope sensor (64, 66) embedded into an electrocardiography monitor (12), which correlates syncope events and electrocardiographic data. Physiological monitoring can be provided through a lightweight wearable monitor (12) that includes two components: a flexible extended-wear electrode patch (15) and a reusable monitor recorder (14) that removably snaps into a receptacle (25) on the electrode patch (15). The wearable monitor (12) sits centrally on the patient's sternal midline (16) and includes a unique narrow "hourglass"-like shape, significantly improving the ability of the monitor to cutaneously sense cardiac electrical potential signals, particularly the P-wave and QRS interval signals. The electrocardiographic electrodes (38, 39) on the electrode patch (15) are tailored for axial positioning along the midline (16) of the sternum (13) to capture action potential propagation in an orientation that corresponds to the aVF lead in a conventional 12-lead electrocardiogram, which senses positive P-waves (271).
Abstract:
The low profile of the flexible tooling system (100) disclosed allows for flexible tooling to be added to nearly all CNC machines with an accommodating z-axis height and allows easier relocation of the system (100) from one CNC machine to another. The system includes one or more pods (2), each of the pods (2) of the system (100) replacing the function of four independent actuators of earlier systems but operating with a shared mechanical frame. Arranging the mechanism into groups of four allows for greater density of part support spacing, minimizes cable requirements, and allows for air (102), vacuum (103), and vacuum sensor (20) requirements be localized on each pod. The pods allow for part supports to be spaced as close as 6" in the x and y axis. An increased variable position assembly density allows for greater flexibility to hold complicated parts.
Abstract:
Physiological monitoring can be provided through a wearable monitor (12) that includes a flexible extended wear electrode patch (15) and a removable reusable monitor recorder (14). A pair of flexile wires (61, 71) is interlaced or sewn into a flexible backing (20), serving as electrode signal pickup and electrode circuit traces. The monitor (12) sits centrally on the patient's chest along the sternum (13), which significantly improves the ability to sense cutaneously cardiac electric signals, particularly those generated by the atrium. To counter the dislodgment due to compressional and torsional forces, non-irritating adhesive (43) is provided on the underside, or contact, surface of the electrode patch (15), but only on the distal (30) and proximal ends (31). Interlacing the flexile wires (61, 71) into the flexile backing (20) also provides structural support and malleability against compressional, tensile and torsional forces.
Abstract:
Physiological monitoring can be provided through a wearable monitor (12, 180) that includes two components, a flexible extended wear electrode patch (15, 181) and a removable reusable monitor recorder (14). The monitor (12) sits centrally (in the midline (16)) on the patient's chest along the sternum (13) oriented top-to-bottom. The placement of the monitor (12) in a location at the sternal midline (16) (or immediately to either side of the sternum (13)) benefits extended wear by removing the requirement that ECG electrodes be continually placed in the same spots throughout the monitoring. Instead, the patient can place an electrode patch (15) anywhere within the general region of the sternum (13). Power is provided through a battery (71, 197) provided on the patch (15, 181). The monitor (12, 180) further includes sensors (42, 69, 75, 191-195) for monitoring patient's air flow and respiratory measures contemporaneously with the ECG monitoring.
Abstract:
Physiological monitoring can be provided through an actigraphy sensor (64) imbedded into an electrocardiography monitor (12), which correlates movement and electrocardiographic data. Physiological monitoring can be provided through a wearable monitor (12) that includes two components, a flexible extended wear electrode patch (15) and a removable reusable monitor recorder (14). The monitor (12) sits centrally on the patient's chest along the sternum (13). The patient can place a patch (15) anywhere within the general region of the sternum (13). The occurrence of actigraphy events are monitored by the recorder (14) through an actigraphy sensor (64). Actigraphy becomes a recordable actigraphy event occurrence when the movement of the monitor (12) and, therefore, the patient (10, 11), exceeds a criteria threshold of acceleration or deceleration as detected by the actigraphy sensor (64). Certain actigraphy event occurrences are considered actionable, of sufficient importance to warrant flagging for further consideration to a following physician.
Abstract:
Control over the wastewater purification can be achieved through controlling delivery of gas-dispersion return sludge solely (36) to an aerobic reaction vessel (16). The gas-dispersion return sludge (36) is created using pure oxygen or oxygen containing trace amounts of ozone as a reactive gas (37), which is blended with return sludge (35) to create a gas-liquid mixture, which is pressurized with an atomizer pump (22), and then at a pressure of not more than approximately 5.5 MPa, the mixture is passed through an atomizer (24) which uses cavitation or ultrasound at a frequency of less than 12,000 KHz to instantly render the reactive gas in the mixture to an ultra-fine bubble state. A portion of the gas is placed into a dissolved state, reaching a state of supersaturation with a high DO value of 20 - 40 mg/l, and causing the remaining ultra-fine bubbles to create an ultra-fine bubble condition
Abstract:
R-R interval data is presented (24) in a format that includes relevant near field and far field ECG data. The near field view (51) provides a "pinpoint" classical view at classical recording speed. The far field view (52) provides an "intermediate" lower resolution, pre- and post-event view. Both ECG data views (51, 52) are temporally keyed to the extended duration R-R interval data (53) that is scaled non-linearly to maximize the visual differentiation for frequently-occurring heart rate ranges. The views (51, 52, 53) are presented simultaneously and their durations are flexible and adjustable. Diagnostically relevant cardiac events can be identified (23) and located to allow pre- and post-event heart rhythm data. The pinpoint "snapshot" and intermediate views of ECG data (56, 166) with the extended term R-R interval data (53) comparatively depicts heart rate context and patterns of behavior prior to and after a clinically meaningful arrhythmia or patient concern.
Abstract:
Physiological monitoring can be provided through a wearable monitor (12) that includes two components, a flexible extended wear electrode patch (15) and a removable reusable monitor recorder (14). The placement of the monitor (12) in a location at the sternal midline (16) (or immediately to either side of the sternum) benefits extended wear by removing the requirement that ECG electrodes be continually placed in the same spots throughout the monitoring. The monitor (12) can interoperate wirelessly with other physiology and activity sensors (131) and mobile devices (132). An application (132) executed by the sensor (131) or device (133) can trigger the dispatch of a wearable monitor (12) to the patient upon detecting potentially medically-significant events. The monitor (12) would then be capable of providing precise medically-actionable data. The patient (10, 11) can then use the sensor (131) or device (133) to record the placement and use of the monitor (12).

Physiological monitoring can be provided through a wearable monitor (12) that includes two components, a flexible extended wear electrode patch (15) and a removable reusable monitor recorder (14). The monitor (12) sits centrally (in the midline (16)) on the patient's chest along the sternum (13) oriented top-to-bottom.

Instead, the patient can place a patch (15) anywhere within the general region of the sternum (13). Ensuring that the quality of ECG recording remains constant over an extended period is provided through self-authentication of patches (15). The recorder (14) implements a challenge response scheme upon being connected to a patch (15). Failing self-authentication, the recorder (14) signals an error.
