Abstract: A multi-sensor mounting system and method includes a secondary pipe and an adapter. The secondary pipe comprises a fastening device configured to fix the secondary pipe to the process pipe, and a valve that is switchable between an open state and a closed state. The adapter detachably connects a sensor module to the secondary pipe. The valve allows a sensing probe of the sensor module being inserted into the process pipe in the open state, and to block a fluid flow in the secondary pipe in the closed state, for example, for times when the sensing probe is removed from the secondary pipe.

Abstract: A method of measuring the transit time of an ultrasonic wave in a medium, by passing an ultrasonic wave pulse through a timing path in the medium, receiving the ultrasonic wave pulse at the exit of the timing path and comparing a first signal representative of the ultrasonic wave pulse on entry to the timing path with a second signal representative of the ultrasonic wave pulse received at the exit of the timing path. At least one cycle and associated zero-crossing point of the first signal is correlated with a corresponding cycle and zero-crossing point of the second signal, and the time interval is measured between the zero crossing points, in order to determine the transit time of the ultrasonic wave through the medium. The method is useful in a sensor for measuring gas composition, as well as bulk gas flow velocity. The sensor and method may be used in a dual channel apparatus for investigating vapour sorption by a substrate.

Abstract: A demand side management control system and method for altering power consumption on an electrical device during specified periods of time (e.g., peak energy demand periods). The system includes a memory to store two or more power consuming function profiles corresponding to the one or more power consuming functions associated with the electrical device. The system also includes at least one processor coupled with the memory. The processor is programmed to receive a peak energy demand signal and access the power consuming function profiles associated with the electrical device. The processor identifies, based on the received peak energy demand signal, the one of two or more power consuming function profiles to be implemented in the electrical device. Finally, the processor periodically disables or operates at a reduced power level at least one power consuming function according to the identified power consuming function profile.

Abstract: A semi-flexible tube is captured between a valve body and a connection device wherein at least one of the valve body and the connection device is connected structurally to a range instead of relying on the manifold tube as the location mechanism for precisely locating the valve at a desired location on the range.

Abstract: A fingerprint sensor package preferably includes a fingerprint sensing integrated circuit in a housing, and a circuit substrate comprising first and second portions connected together. The first portion is within the housing and mounts the fingerprint sensing integrated circuit, and the second portion is flexible and extends outwardly from the housing for facilitating electrical connection to the fingerprint sensing integrated circuit from external to the housing. Each portion of the circuit substrate preferably includes at least one insulating layer and at least one electrical conductor thereon. Accordingly, the package can be made relatively compact and electrical interconnections are facilitated by the second portion or extension of the circuit substrate. In one embodiment, the first and second portions are integrally formed together. In this embodiment, the first portion is also flexible. The sensor package is readily included on the upper surface of a laptop computer, for example.

An electrostatic discharge (ESD) circuit is provided within the housing and is connected to the at least one external electrode. An isolation circuit is connected to the at least one line of the processing circuitry for external connection. The external electrode and ESD circuit, as well as the line isolation circuit protect the integrated circuit against damage by voltage transients, such as ESD. The at least one external electrode may include first and second external electrodes. The first electrode may be connected to the electrostatic discharge circuit.

Abstract: A fingerprint sensor includes an array of fingerprint sensing elements; analog-to-digital (A/D) converters having a controllable range; a scanner to perform sequential A/D conversions of predetermined ones of the array of fingerprint sensing elements; and a range determining and setting circuit for controlling the range of the A/D converters based upon prior A/D conversions to thereby provide enhanced conversion resolution. A plurality of A/D converters are preferably used for simultaneously converting analog signals from a corresponding plurality of fingerprint sensing elements. The A/D converters may include at least one reference voltage input for permitting setting of first and second points of the range. The range scale determining and setting circuit may generate a histogram based upon prior A/D conversions. In addition, the range scale determining and setting circuit may set a default range for initial ones of the fingerprint sensing elements.
