Abstract: An apparatus is disclosed for magnetically sensing and computing and displaying cable distance, and computing and displaying other user-selectable information in a pipe inspection system. At least two permanent magnets are mounted in spaced apart fashion, on either a frame, or a rotatable member supported on the frame for rotation about an axis. A magnetic sensor is mounted on the other one of the rotatable member or frame on which the magnets are not mounted, so that either the magnets rotate around the magnetic sensor or the magnetic sensor rotates between the permanent magnets. The magnetic sensor generates signals representing changes in at least two axes in a composite magnetic field generated by the permanent magnets.

Abstract: Methods and devices for improving measurements of test meter, and in particular for detecting a presence of an electrochemical sensor or strip in the test meter and a start time of an electrochemical reaction, are provided. In one exemplary embodiment of an electrochemical system includes an electrochemical sensor, a test meter, and a circuit. The circuit is configured to form an electrical connection with the electrochemical sensor such that the circuit can detect three distinct voltage ranges. The voltage ranges can be indicative of an absence of the electrochemical sensor, a presence of the sensor that is devoid of a sample, and a presence of the sensor with a sample. Test meters, methods for detecting when a sample starts to fill an electrochemical sensor for establishing when a reaction starts, and circuits for use with electrochemical strips, are also provided.

Abstract: A camera based sewer evaluation vehicle has an electro-scan pipe defect detection system integrated therein. A cable and winch of the camera based system are utilized to support either a camera or an electro-scan probe. A signal transmitted through the cable is passed along for processing of signals received through the cable for final output and analysis, such as on a common computer. To facilitate electro-scan probe based pipe defect detection, a ground rod is utilized. The system can include a funnel plug downstream of the electro-scan probe for interconnection to a haul line and to assist in maintaining a liquid filled status in the pipe adjacent the electro-scan probe. A downstream bypass funnel plug or a blockade of some form can operate within and past a downstream manhole adjacent the pipe to keep the pipe filled with liquid.

Abstract: Described herein are systems and methods to utilize factual information based on stored analyte data to allow greater insight into the management of diabetes of a user.

Abstract: The system utilizes electroscan equipment including a voltage source and current meter with a cable having one end grounded and one end having an electric probe thereon sized to fit within an underground pipe. The probe is able to complete an electric circuit back to ground when the probe is adjacent a defect through which electric currents can pass, thus producing varying electric current. A cable reel is provided with portions of the cable supported thereon and with a cable distance sensor coupled to the reel along with the current meter and voltage source in the form of a battery. The current meter and distance sensor transmit wireless signals to an on-site processor, such as a smartphone, for on-site data evaluation. Such unconditioned data is also transmitted to a remote location for conditioning of the data and retransmission of the conditioned data back to the on-site processor.

Regardless of distance between the client and server, complete synchronization between the mouse movement, or any other updates to the three-dimensional model, and the rendered result is attained.

Abstract: Tomographic data representing an imaged three-dimensional object is divided into macro blocks and filtered by visibility and presence in a projected frame of a rendered three-dimensional object to speed rendering of the object. The data are loaded and rendered in parallel for improved speed and capacity.

Abstract: This patent application is for a method and system that takes any arbitrary pre-existing geometric data and builds ISO 19107 compliant 3-Dimensional (3D) topology rather than requiring an incremental build of the topology.

Abstract: A method for optical detection of lipofuscin concentrations in the retina is described. A subject's eye is exposed to a light source. Light emitted from the subject's eye is detected. Levels of lipofuscin are determined from the emitted light. A system for optical detection of lipofuscin in the retina is described. The system includes a light source to generate light. The system includes an optical detector in optical communication with the light source. The optical detector is configured to detect light emitted from a subject's eye. A computing device in electronic communication with the optical detector is included in the system to determine levels of lipofuscin from the emitted light.

Abstract: An optical mark recognition tabulation device includes a guide channel including opposing integral sidewalls configured to laterally constrain a test sheet as the test sheet is fed past a set of optical sensors. The optical sensors are aligned with optical entry indicia on the test sheet to sense marks on the optical entry indicia as the test sheet is fed past the optical sensors. The optical mark recognition tabulation device further includes a recessed channel located along at least a substantial portion of a side of the guide channel. The optical mark recognition tabulation device further includes a spacer strip configured to be received within the recessed channel and effectively reduce the width of the guide channel such that the guide channel is reconfigured to laterally constrain a different size of test sheet when the spacer strip is received within the recessed channel.

Abstract: A process for the detection of flaws in an article comprising infra-red scanning of the article as its temperature changes and comparing the infra-red scans for regularity of cooling/heating pattern. Where the article is irregular, such as in marginal areas, thermodynamic modelling is performed to establish a hypothetic cooling/heating pattern for an unflawed article.

Abstract: Saliva samples are collected for body fluid constituent analysis by placing a sponge member into a patient's oral cavity. The sponge member is formed similarly to a pacifier nipple. Saliva is absorbed. The saliva is then expelled from the sponge member into a pipette. A filter may be placed between the sponge member and the pipette, through which the saliva is cleaned and molecular weight-selectively prepared by letting only substances through with a molecular weight below a cut-off weight. The integral unit is dismembered after the saliva has been transferred into the collection pipette, and the latter is tightly closed off for further handling.

Abstract: A method and ink composition are disclosed that utilize two mechanisms for the purpose of indicating the approximate age of an ink that has been deposited on a writing surface. The first mechanism relates to detecting color shifts of pH sensitive compounds in the ink as the result of the evaporation of certain acidic or basic chemicals thereof. The second mechanism relates to the oxidation of compounds in the ink. Spectroscopically generated curves are plotted as the ratio of reactants to products, versus time. The spectral characteristics of the ink are determined in units of percent reflectance of the active compounds in the ink so that the age of the ink can be computed by reference to known reaction rates. A plurality of dyes having differing reaction rates may be added to the ink to enable precise measurements to be made over different time intervals.
