Abstract: Systems, devices, and methods relate to utilizing an electronic caliper to analyze an electronic electrocardiogram (ECG). An example method for includes outputting, by a display, an electronic ECG within a graphical user interface (GUI). An electronic caliper is output, by the display, as overlaid on the electronic ECG within the GUI. The electronic caliper includes a first electronic tip and a second electronic tip. The method further includes receiving, by a user input device, a user input signal and moving, based on the user input signal, the first electronic tip, the second electronic tip, or both the first electronic tip and the second electronic tip, relative to the electronic ECG within the GUI.

Abstract: Described are techniques to provide event data to users. Event data corresponding to one or more events may be received from a first device. Availability data corresponding to availability of a user regarding events may be received from a second device. The event data that corresponds to at least a portion of user data associated with the second device may be determined, and at least a portion of the event data is provided to the second device. Rating data acquired or generated by a device present at the event location may be used to adjust a rating metric associated with the event.

Abstract: A ground fault detection circuit for detecting ground faults in electrical subsea conductor lines including a first electrical conductor line, a second electrical conductor line, a first ground fault detection line, and a second ground fault detection line. The ground fault detection circuit further includes a first resistor operatively connected to a voltage source and the first ground fault detection line, a second resistor operatively connected to the voltage source and the second ground fault detection line, and a voltage detection device configured to detect the voltage at an output end of the first resistor to determine the presence of a ground fault in at least one of the first and second conductor lines.

Abstract: A method for controlling a subsea valve assembly includes connecting a subsea riser between a wellhead and a surface vessel. An in-riser control unit is attached to a wired pipe string and disposed within the subsea riser, resulting in the in-riser control unit being deployed in-riser. The wired pipe string is connected to a surface control unit and a communication signal is transmitted through the wired pipe string between the surface control unit and the in-riser control unit to control the subsea valve assembly.

Abstract: An animal deterrent system to be placed on structures such as electrical apparatus to deter and protect birds, wildlife and other animals. Specifically, a perching deterrent having a saddle made to fit over any desired member of a structure and deterrent extensions may be used separately or in combination. The deterrent extensions may protrude in various configurations from the above-mentioned saddle to inhibit, deter, or insulate animals contacting structures. Also possible is an insulator cap with spiral conductor covers.

Abstract: An apparatus for repairing a pair of non-conforming bushings on the M89E1 Declutching Ammo feeder for the M197 machine gun. The apparatus includes a central body and a pair of large drill plates which allows a user to drill out the non-conforming bushings from the ammo feeder. The user then press fits replacement bushings into the ammo feeder. The apparatus also includes a pair of small drill plates which allows the user to drills pin mounting holes into the replacement bushings.

Abstract: A phase detector detects a phase difference between a first and second signal received by a phase detector. A charge is supplied by a charge pump circuit that corresponds to the phase difference using a phase difference to charge conversion that is substantially linear and nonzero in a phase error region that includes a phase error transition region around a phase error of zero having both negative and positive phase error values. Dual determinations, q1 and q2, offset from each other are made, of an appropriate charge for a given phase error between the first and second signals. The charge pump supplies as the total charge pump output a charge value representing a combination of q1 and q2, thereby providing a phase error to charge conversion that is substantially linear in the phase error transition region around zero.

Abstract: There is a valve assembly for controlling the admission of a fluid such as air into a vehicle tyre or other pressure vessel. The assembly includes a housing (1) with a valve assembly (10) movable therein by a predetermined pressure in said vessel against a spring 5A. The valve member (10) is movable from a first position at which ports (14) of an inlet passage (13) in the housing (1) are open to fluid flow into the vessel to a second position at which the ports (14) are closed by the valve member (10). In use of the valve assembly when the valve member (10) is biased to the first position by the spring 5A the fluid can flow into the vessel until pressure therein reaches the predetermined pressure and the valve member (10) is moved to the second position to terminate flow into the vessel. The valve assembly also includes a low pressure indicating means comprising a transparent cap 3A with an opaque band (23) and a collar (8) movable with the valve member (10).

Abstract: A method and apparatus for dielectric drying is disclosed wherein a load to be heated positioned on a carrier the bottom of which provides a secondary electrode is moved with the carrier a dielectric heating chamber having a primary electrode positioned above load when said load on said carrier is moved into an operative position in the chamber. The carrier and load are elevated into heating position and this movement simultaneously connects the secondary electrode to ground, so that when high frequency power is applied to the primary electrode the circuit is made to dielectrically heat the load.

Abstract: A yarn texturing machine has a texturing section spaced from a creel section by an operator's aisle. Setting heaters are located upright in proximity with the creel, and have their bottom inlet ends well above floor level and their top exit ends extending above the creel. Yarn cooling and stabilizing guides span the aisle and are downwardly inclined from the top ends of the setting heaters towards the texturing section.

Abstract: Each station of a row on a multistation yarn texturing machine comprises a common support unit for all driven members of that station, the driven members being interconnected for synchronous operation by a transmission system which includes a coupling member such as a toothed belt, and the support unit being movable for engaging or releasing the coupling member from a single machine drive member common to all the stations of a row and preferably consisting of a shaft with toothed wheels for driving the coupling members.
