Ink jettable, radiation curable overprint compositions containing at least one radiation curable oligomer/monomer, at least one photoinitiator, and at least one surfactant are disclosed. The overprint compositions are particularly well-suited for protecting ink-based and toner-based images on substrates subjected to abrasives, heat, and/or sunlight since the compositions protect such images from smearing, cracking, and fading.

An adjuster for pivotally adjusting two vehicle parts to each other, is provided, the adjuster including a spindle pivotally arranged on the one vehicle part about a first pivot axis, an adjusting gear unit which includes a gear unit housing and is in engagement with the spindle via a spindle nut, and a holder arranged at the other vehicle part, which pivotally supports the adjusting gear unit on the other vehicle part about a second pivot axis and for this purpose at least partly encloses the gear unit housing of the adjusting gear unit in circumferential direction about the second pivot axis. The holder may be formed by a plastic retaining clip to form a light-weight and inexpensive adjuster that has high strength in operation.

The invention relates to an adjusting means (2) for pivotally adjusting two vehicle parts to each other, with a spindle (21) pivotally arranged on the one vehicle part about a first pivot axis (210), an adjusting gear unit (22) which includes a gear unit housing (23) and is in engagement with the spindle via a spindle nut (221), and a holder (3) arranged at the other vehicle part, which pivotally supports the adjusting gear unit on the other vehicle part about a second pivot axis (220) and for this purpose at least partly encloses the gear unit housing of the adjusting gear unit in circumferential direction about the second pivot axis (220). It is provided that the holder is formed by a plastic retaining clip (3). In this way, an adjusting means is created, which can be formed light-weight and inexpensive, but yet with high strength in operation.
摘要:
A source generates an optical test signal sweeping a bandwidth of wavelengths over time. The test signal is applied to a device under test (DUT) to generate a response signal. A timing signal generator connected to the source generates a timing signal having triggers at time instances corresponding to known wavelengths of the test signal. A DUT detector samples the DUT response signal generating sampled DUT data using a sampling period that is shorter than a shortest time between timing signal triggers. A correlator receives the timing signal, the known wavelengths associated with the timing signal triggers, the sampled DUT data and the DUT detector sampling period then correlates each sampled DUT datum to a wavelength of the test signal that was applied to the DUT when the DUT datum was sampled by interpolating the known wavelengths using the trigger time instances and the DUT detector sampling period.

An optical power meter including a photodiode having a surface for receiving a beam of light, a thermo-electric cooler for maintaining the photodiode at a predetermined temperature, and a current monitor for measuring a drive current passing through the thermo-electric cooler allows dark current drift arising from a varying thermal gradient across the active region of the photodiode to be corrected, thus improving stability of the optical power meter. More specifically, by monitoring the TEC drive current, and applying a correction factor to the optical power readings, the stability of optical power readings is improved by an order of magnitude.

A tunable laser system having fine and coarse wavelength discrimination is provided. The tunable laser system includes a first filter having a first free spectral range (FSR) and a second filter having a second FSR different from the first FSR. The first filter provides a first series of pulses from a first portion of a laser output, and a second filter provides a second series of pulses from a second portion of the laser output. A processing system compares the first series of pulses and the second series of pulses to identify a series of markers, in which the markers are separated by a beat period of the first series of pulses and the second series of pulses. Advantageously, the series of markers may be used for mode-hop detection and/or for wavelength referencing.
摘要:
There are provided embodiments of a sensing device that comprise a sensing element, a substrate, and a bonding element, each being selected for environments that utilize caustic working fluids such as automotive fuel. Material for use as the bonding element can form molecular bonds with ceramics and glass. In one embodiment, the sensing device comprises a receptacle or cavity, in which are located the sensing element and the bonding element. This configuration facilitates the formation of bonds between the bonding element and each of the sensing element and a peripheral wall of the cavity. Such bonds are configured in a tensile bonding area and a shear bonding area, the combination of which is useful to secure the sensing element in the cavity. The sensing device can further comprise a seal such as an o-ring disposed in annular relation to the substrate to seal the sensing device to a peripheral device such as a fluid fitting, which may be found in a fuel system of an automobile.
