  • Patent number: 9250277
    Abstract: A high resolution, high reliability, magnetically coupled, linear position sensor (50) provides a means of determining the position of an object (51) using a methodology that does not require a direct mechanical or physical connection between the sensor (50) and the object (53) whose position is to be determined. The sensor (50) can operate in a high temperature, high pressure fluid with exposure to moderate levels of radioactivity. The sensor (50) utilizes dual rod elements with a magnetically coupled bridging contact slider (51) supported by a ceramic guide all of which are contained within a non magnetic pressure housing. The topology of the sensor (50) supports at least two types of measurement techniques, Time Domain Reflectometry (TDR) as well as linear resistive to determine target (51) position.

  • Patent number: 9172246
    Abstract: Phase balancing techniques for power transmission systems are disclosed. In one embodiment, a phase balancing protocol (240) includes executing a first phase balancing protocol (350) in relation to a first power transmission section (400a). A second phase balancing protocol (370) may be executed if the first phase balancing protocol (350) is unable to provide a phase balanced condition. The first phase balancing protocol (350) may utilize a first ordering sequence (364) to rank the current flow on the power lines (16) of the first power transmission section (400a), while the second phase balancing protocol (370) may utilize a second ordering sequence (384) to rank the current flow on the power lines (16) of the first power transmission section (400a). The order sequences (364, 384) are opposite of each other—one ranks the current flows from high-to-low, and the other ranks the current flow from low-to-high.

  • Patent number: 9151591
    Abstract: A position measuring system detects an extreme position of a guide rod which extends along a path that is rectilinear relative to a guide system and can be moved along the rectilinear path, wherein the system operates reliably, and requires a minimum of electrical lines. The position measuring system is equipped with a plurality of sensor elements and a magnetic element, wherein the magnetic element is configured to form a magnetic field. The magnetic element is connected to the guide rod. Each sensor element is configured to detect a magnetic field within a detection region, a field strength of the magnetic field being greater at the location of the sensor element than a predefined threshold value. At least one sensor element is connected to the guide system and is arranged in an environment of the path. A corresponding measuring method uses the position measuring system to detect the extreme positions.

  • Patent number: 8004422
    Abstract: A programmable telemetry circuit that may be programmed for high bandwidth, low Q; low bandwidth, high Q; or for other parameters. The programmable telemetry circuit may include a first coil; a high impedance path having a first node connected to a first node of the first coil; a low impedance path having a first node connected to the first node of the first coil; a capacitive path having a first node connected to a second node of the first coil; and an input path for coupling signals into the high impedance path, the low impedance path, and the capacitive path. The low impedance path may be connected in parallel with the high impedance path. The capacitive path may form a circuitous path with the high impedance path and the low impedance path. The programmable circuit may be programmed to select the high impedance path or the low impedance path.

  • Patent number: 7518529
    Abstract: A monitoring device (1) for monitoring the electrical properties of a medium voltage overhead line (3) in a medium voltage network comprises three separate measurement sensors (2a, 2b, 2c), each being adapted for direct connection onto a medium voltage overhead line. Each of the measurement sensors has means to draw operating power from the medium voltage overhead line. The measurement sensors measured results may be combined for accurate measurement analysis.

  • Patent number: 7154414
    Abstract: A system and method for monitoring vehicle tire pressure. A tire pressure monitor for each tire includes a pressure sensor for sensing tire pressure, a transmitter for transmitting a tire pressure signal representative of the sensed tire pressure, and a batter providing power to the transmitter. To conserve battery power, each tire pressure signal transmitted by the transmitters includes a wake-up signal only when the vehicle has been stationary for a predetermined time period. The wake-up signal ensures receipt of the tire pressure signal by a vehicle mounted receiver alternating between active state and inactive states.

  • Patent number: 6515594
    Abstract: Two different types of data transfer are provided. The first type of data transfer takes place between a data transfer device and each individual measuring point. This first type of data transfer requires close physical relation between the data transfer device and the measuring point. The measuring point is provided with a marker, or a marker is retrieved, within the framework of this data transfer. Then a second type of data transfer between a central control and the measuring point is realized. Measurement data, control data, and, if necessary, configuration data are transferred within the framework of this second data transfer. The marker can be made application specific or sample specific by means of this procedure of the measurement arrangement, that is, it is possible to allocate markers which refer to the application. Furthermore, the measurement arrangement makes sample management and documentation possible without expensive editing processes.

  • Patent number: 6429786
    Abstract: The invention relates to a sensor and evaluation system for capturing data at a measuring station (3), in particular for use in double sensors for determining end positions and limit values. The individual sensors (1, 1′, 2, 2′, 16, 16′) are operated as sensor pairs (1″, 2″, 16″) by a largely shared control circuit consisting of two connecting lines (5, 6) with an electric current or voltage of alternate polarity. A state of a sensor (1, 1′, 2, 2′, 16, 16′) is transmitted on the corresponding half-wave of the sensor current and evaluated by a switching amplifier (13) in relation to polarity and amplitude. Said sensor and evaluation system reduces the number of connecting lines required. In addition, interference from neighboring sensors is largely excluded, so that sensors can be mounted more closely together in a system. Said sensor and evaluation system is especially suited for equipment required to comply with the DIN 19234 (NAMUR) standard.
