摘要:
Methods and devices for increasing a sensor resolution are disclosed. In one example, a two measurement process is used. A first measurement is used to effectively measure across a full range (e.g. 0 to 5 VDC) of the sensor. This first measurement may identify the current operating point of the sensor (e.g. 3.5 VDC). A second measurement may then be made to effectively measure across a sub-range of the sensor that encompasses the current operating point of the sensor (e.g. across a sub-range of 3.0 to 4.0 VDC for a current operating point of 3.5 VDC). The gain of the amplifier may be raised during the second measurement to produce a higher resolution measurement. In some cases, the first measurement may be used to determine an appropriate offset that may be applied so as to scale the amplifier to the desired sub-range of sensor that includes the current operating point of the sensor. In some cases, the two measurements may be used together to compute an effectively higher resolution measurement signal. In some cases, this may allow for a smaller and/or cheaper sensor to be used, while still achieving good results.

A force sensor apparatus and method of forming the same. The apparatus includes a force sense element that can be attached to a substrate. An actuator disposed in a hole formed within the cap is operably coupled to the force sense element for transferring force to the sense element in response to receiving a force from an external source. The force sense element is configured to sense the external force and generate an output signal representing the force. Preferably, one or more bond pads, associated with the force sense element and the substrate, can be electrically connected via wire bonding. A cover associated with an integrated flexible membrane can be mounted on the substrate in order to protect internal components associated with the force sensor apparatus from an external environment.

A stent device including a stent body having a plurality of adjacent rows and one or more interconnections or interlocking rings between rows. The interconnections have first and second connecting portions with first ends permanently and immovably coupled to the rows and second ends interlocked with each other, such that the second ends of each portion can move independently of the other. The interconnections include ball and socket joints, hinge joints or universal joints. Interlocking rings have indentations for receiving the other ring, such that when interlocked, the rings will lay flat against a body lumen wall.

A combined reach can be determined for multiple resources. Usage data, including audience duplication data, is used to generate audience duplication measurements for pairs of the resources. A child-resource pair is identified, and the audience duplication measurement for that resource pair is modified. The modified measurement is used to determine a combined reach for the multiple resources. A report is also generated based on the combined reach.

The present disclosure relates to sensors that are exposed to media during use. In some cases, a sensor assembly includes a sensor element positioned on a substrate, where the sensor element may be mechanically and electrically connected to the substrate and may be in fluid communication with a media inlet port. The sensor assembly may include a cover sealed to the substrate of the sensor assembly to enclose the sensor element in a sealed chamber. In some instances, the sensor assembly may include a bonding layer on the substrate of the sensor assembly, and the cover may be sealed to the bonding layer to form the sealed chamber. In some instances, the sealed chamber may help provide a fail-safe media seal for the sensor assembly in the event the sensor element forms a leak during use.

The present disclosure relates to sensors including pressure sensors, humidity sensors, flow sensors, etc. In some cases, a connector assembly for a sensor assembly may include an electrical connector, a printed circuit board and a conductive outer housing. The electrical connector may include a mechanical connector and electrical terminals exposed at a first end and at a second end of the mechanical connector. The electrical connector, printed circuit board and conductive outer housing may all be electrically connected to one another. In some instances, a plurality of electrical connectors having different mechanically shaped second ends and similarly shaped first ends may be provided, from which one electrical connector may be chosen for use in the connector assembly.
摘要:
A modular sensor assembly in which a sensing module may be packaged and provided separately from a signal processing module and which, in some applications, may facilitate disposal and/or replacement of the sensing module when exposed to a “dirty” or “contaminated” environment without requiring disposal and/or replacement of the entire sensor assembly. In certain applications, the sensing module may include at least one transducer or sensor and a local memory containing a set of conditioning coefficients. The sensing module may be removably coupled to a signal processing module which, in some cases, may be configured to download the set of conditioning coefficients stored in the local memory of the sensing module, and to use the set of conditioning coefficients to produce a substantially linearized output signal.

Provided area cleaning apparatus and an associated method of using the disclosed apparatus wherein the apparatus utilizes one or more nozzles configured to provide a coherent stream of one or more cleaning fluids for removing accumulated fine particulate matter, sludge, from surfaces. The nozzles may be sized, arranged and configured to provide coherent streams that maintain the initial stream diameter for a substantial portion of the maximum dimension of the space being cleaned. The apparatus and method are expected to be particularly useful in the cleaning of heat exchangers incorporating a plurality of substantially vertical and narrowly spaced tubes by directing cleansing streams along a plurality of intertube spaces.
