Abstract: Pre-connected analyte sensors are provided. A pre-connected analyte sensor includes a sensor carrier attached to an analyte sensor. The sensor carrier includes a substrate configured for mechanical coupling of the sensor to testing, calibration, or wearable equipment. The sensor carrier also includes conductive contacts for electrically coupling sensor electrodes to the testing, calibration, or wearable equipment.

Abstract: Techniques and solutions are described for detecting potential problems with web pages. For example, a web page can be analyzed (e.g., during loading of the web page) to determine statistics, such as size and structure statistics. The web page can be compared, using the statistics, to a statistical model representing the web page to determine if the web page is consistent with the statistical model. The statistical model can be created from previous page loads of the web page. Problems such as web page spoofing can be detected if the same web page content (e.g., content with a high degree of statistical similarity) is obtained from two different web sites. For example, a web page that is retrieved from one web site that matches a statistical model representing the same web page from another web site can indicate a spoofed web page.

Abstract: A hold-and-release device for the movable lower guard of a hand-operated circular saw in which the guard is held in its out-of-the-way position by a magnet or latch while a saw cut is being made but is automatically released to assume its normal protective position when the motor power is removed. Alternatives are described having different degrees of complexity, for example, one requires the operator to apply pressure to the trigger switch while engaging the guard-holding device.

Abstract: A low noise ion detector has reflective parts coated for absorbing stray photon and neutral particles.

Abstract: A modular channel electron multiplier mounting arrangement for an analytical instrument, which reduces the labor required for assembly and, at the same time, results in a more rigid structure with lower susceptibility to microphonic noise has been developed. A circuit board and an attached end support has slotted portions for engaging support studs on the instrument. A channel electron multiplier is mounted on the circuit board by means of supporting hardware. Printed circuit wiring on the circuit board carries signal and high voltage to receptacles on the circuit board which when installed in the instrument are aligned for securely engaging leads in the instrument. The end support and the receptacles rigidly support the assembly in the instrument such that microphonics noise is significantly reduced.

Abstract: An ion detector in which conversion dynode means are placed near a microchannel plate means for receiving and amplifying converted ions.

Abstract: Scanning electron microscopy apparatus employing a detector to detect emission of electrons resulting from the impingement of electrons of an electron beam on an object being viewed, the apparatus including an electron beam source providing the electron beam, a magnet providing a magnetic field to direct the electron beam to the object, a first microchannel plate having a first hole through it aligned with the electron beam, a first surface directed toward the electron beam source for receiving low energy electrons that have been emitted from the object and directed through the hole by the magnetic field, a second surface on the opposite side of side first microchannel plate for discharge of multiplied electrons, and a first anode facing the second surface, the first anode being positioned to collect electrons discharged from the second surface.

Abstract: An ion detector including a microchannel plate (MCP) with a hole through it provided along an undeflected trajectory of an ion beam, a faraday cup in position to receive ions passing through the hole, and a deflector to selectively deflect ions to multiplying channels of the MCP.

Abstract: A crystal-controlled oscillator of integrated circuit design, comprising, a three-stage direct-coupled amplifier employing insulated gate field-effect-transistors and overall resistive negative (DC) feedback for bias stabilization thereof. The oscillator is designed to operate at a frequency at which the reactive network, including the inherent interelectrode capacitances of the field-effect-transistors, of the amplifier results in a loop phase shift which satisfies the Barkhausen Criterion.
