Abstract: A method and system may input telemetry into a data structure. The telemetry may comprise a plurality of measurement results or other data collected from remote network nodes. Subscriber use metrics may be determined from the telemetry. From the use metrics and habits of the subscriber, user characteristics may be determined. A likelihood of service cancellation, based on the user characteristics, may be estimated in an embodiment. In another embodiment, a likelihood of receiving an inquiry from the subscriber at a subscriber support center may be estimated. Service enhancements may be proactively provided to the subscriber, based on the telemetry, the subscriber use metrics and the user characteristics in advance of service cancellation or receiving the inquiry. Last mile equipment may provide telemetry. The last mile equipment may include set top boxes, cellular phones, tablets and the like.

Abstract: A pressure gauge includes: an outer container defining an outer chamber set to a reference pressure (Pr); an inner container disposed in the outer container; and a tube setting the inside of a first inner chamber of the inner container to a measurement pressure (Px). The inner container includes: a cylindrical rigid wall portion; first and second pressure receiving plates that displace due to a differential pressure between the reference pressure and the measurement pressure; a bellows partitioning the inner container into the first inner chamber and a second inner chamber; and a pressure detection element disposed in the second inner chamber and detecting the measurement pressure based on the displacements of the first and the second pressure receiving plates. The outer chamber and the second inner chamber are set to the reference pressure of a high vacuum that is lower than a lower limit of the measurement pressure.

Abstract: A method and apparatus for estimating bitrate, buffering events and/or other QoE metrics of video reception, based on CDN logs, are provided. The method and apparatus may rely on an AI model, including a neural network. The neural network may receive a training data set comprised of a plurality of CDN server logs. The CDN server logs may be associated with known QoE metrics collected from a plurality of user devices. Once the neural network is trained, a CDN server log, without associated QoE metrics, may be received as input. With the trained neural network and the CDN server log, buffering events and average bitrate QoE metrics may be estimated for one or more user devices without explicitly receiving QoE metrics from the user device.

Abstract: A vacuum gauge includes an introduction tube, a diaphragm displaced by a gas to be measured that is introduced from the introduction tube, a piezoelectric element that has one end coupled to the diaphragm and is displaced along with the diaphragm, an inner structure to which a circumferential edge of the diaphragm and the other end of the piezoelectric element are secured and that is coupled to the introduction tube, and an airtight container to airtightly enclose the introduction tube and the inner structure. The inner structure, the introduction tube, and the diaphragm airtightly partition a space in the airtight container into a pressure introduction chamber to which the gas to be measured is introduced on one surface side of the diaphragm, and a reference pressure chamber on the other surface side of the diaphragm. the reference pressure chamber being set at a high vacuum that is lower than the pressure lower limit of the measurement gas.

Abstract: A monitor includes a display panel, a displaying circuit, a connector and a self testing circuit. The self testing circuit has a testing signal generator, a switch circuit and a detecting circuit. When the detecting circuit detects the video signals transmitted from the computer, the detecting circuit switches off the switch circuit so as to avoid the testing signal generated from the testing signal generator being transmitted to the input port of the displaying circuit. When no video signals transmitted from the computer are detected, the detecting circuit switches on the switch circuit to allow the testing signal generated from the testing signal generator to be transmitted to the displaying circuit.

Abstract: A self-cleaning return pump system for use with a clean-in-place system for cleaning vessels includes a recirculation loop for providing flow communication including a return pump, an eductor, and a separator. The return pump is arranged to discharge a liquid through the eductor into the separator and is supplied with a substantially continuous flow of liquid from the separator. A return line provides flow communication between the vessel to be cleaned and a suction port of the eductor. The separator has a top discharge port and a bottom discharge port. The top discharge port is configured to discharge a liquid or a liquid-air mixture therefrom to the clean-in-place system. The return pump causes liquid flowing through the recirculation loop at the eductor to have sufficient dynamic head to draw liquid or a mixture of liquid and air from the vessel through the return line, into the eductor. The liquid or liquid air mixture is discharged into the separator.

Abstract: Improvements are disclosed in a rotary, lobar, positive-displacement pump and in a rotary, centrifugal pump, whereby all product-contacting areas of the pumps can be effectively cleaned without disassembly, i.e., cleaned in place. Non-rotating seals seal the impellers and isolate the pump shafts from the product zone. Each seal has an elastomeric member molded integrally thereto. The seal is biased by the elastomeric member so as to be slidably pressed against an impeller. In the lobar pump, certain passageways can be selectively closed and opened, so as to adapt the pump for being used to pump a pumpable material when closed and for being cleaned by a cleaning solution flowing therethrough when opened. Valves may be alternatively provided for analogous purposes.

Abstract: There is disclosed the utilization of a fluidized bed as a combustion chamber for the combustion in an external combustion engine of the recyclable fuels magnesium, aluminum, and their hydrides and/or alloys. The combustion products serve in whole or in part as the inert media for the bed.

Abstract: A cutter ring for use in trimming printed circuit board leads and a method of forming the ring is the subject of this invention. The cutter member is of annular configuration and is provided with a central hub portion surrounding an aperture. The cutter member itself is formed from a hardened sintered carbide which can only be shaped through a prolonged grinding operation. A molded cap is formed over the hub portion to present a surface which is to be received within a tool holder such as an arbor. The molded cap is characterized by being formed from a relatively soft workable material which can be shaped through a machining operation.

Abstract: A device for extracting both kinetic and potential energy from the motion beneath waves over a considerable depth comprising a power member or sail guided to reciprocate with the movement of the water. The power sail is connected to and operates a power device such as an electric generator or pump. A second member, or sail, is located in geometric position relative to the power sail to reflect energy back to the power sail. Sensors, servo systems, and computers may be used to optimize power output. Multiple units can be arranged in "farms" to furnish megawatts of power.

Abstract: A system of operating an engine on a recyclable, relatively non-polluting fuel. The fuel may include any one or more of the following: magnesium (Mg), aluminum (Al), magnesium plus aluminum, magnesium-aluminum alloy, magnesium hydride (MgH.sub.2) aluminum hydride (AlH.sub.3) and magnesium aluminum hydride (Mg(AlH.sub.4).sub.2). The fuel when burned produces oxides and hydroxides of magnesium and/or aluminum. The oxides and hydroxides can be reduced to magnesium and/or aluminum and/or their hydrides and reformed for reuse in the engine. The system is intended for use not only in automotive engines but also stationary power plants including refrigeration.
