A method of bypassing a programmable processing element can include examining data where the data has at least a header, removing the header from the data (310), encrypting the data through a cryptographic component (325), rejoining the removal header and the encrypted data (330), and outputting the rejoined header and encrypted data (340).

The present invention relates to a centrifugal pump for pumping of liquids containing pollutions mainly in the form of solid particles, which pump comprises a drive unit, a hydraulic unit, whereby the hydraulic unit comprises a pump housing (20) and a pump impeller (12) rotationally arranged inside the housing, the pump impeller comprising an upper (14) and a lower (16) cover disc and a number of intermediate vanes (18). The invention is characterised in that a bottom wall (22) of the pump housing, having a central inlet opening (24), is arranged with at least one spirally extending back flow affecting means (32, 34) on the side facing the lower cover disc extending parts of or full turns around the inlet opening.

A fluid quick connector (30) includes a housing (32) and a sleeve (40) movable between first and second positions within the housing (32) upon engagement with an endform (20) inserted into the housing (32). A retainer (42) mounted on the housing (32) includes at least one radially inward extending protrusion which extends through an aperture (60) in the housing (32) into engagement with the endform (20) to latch the endform (20) in the housing (32). The sleeve (40), when in the first position, blocks extension of the protrusion through the aperture (60) in the housing (32) to allow insertion of the endform (20) in the housing. Movement of the sleeve (40) to the second position allows the retainer (42) to retract moving the protrusion through the aperture (60) in the housing (32) into engagement with the endform (20).

A quick connector includes a male component in the form of a spool fixedly mounted to a fluid conduit and a female component in the form of a housing (12) having a bore (28) open at one end for receiving the male component therein. A latch (22) is rotatably mountable on the spool (18) and is movable relative to a transverse channel in the female component between a first installed position with respect to the channel and a second latched position wherein the latch (22) engages opposed notches (38) in the channel to latch the spool in the housing. At least one latch clip is mountable on the latch and engageable with edges of the channel in the body to resist rotation of the latch from the latched position. An optional secondary latch clip (26) is engageable with the latch clip, the latch and the opposed side edges of the channel to further resist rotation of the latch from the latched position.

The invention proposes a connector having at least one signal contact blade (22a) and an earth contact blade, characterized in that the connector includes at least one protective metal plate (42, 50) that extends opposite a facing portion (34a, 30a) of the first, signal blade (22a) and is electrically connected to an earth contact blade. Thus, any attempt, with the aim of reaching the signal contact blade by means of a metal object, results in an electrical connection being established between the protective cage connected to earth and the first, signal contact blade and in producing a short circuit that is a signal representative of an attempted fraud.

A system for measuring optical detector linearity according to the present invention employs a laser source that illuminates an integrating sphere. The sphere randomizes the laser signal phase and produces a uniform intensity over the sphere output. A collimator expands the sphere output for entry into an interferometer, where the incident optical energy is amplitude modulated in a sinusoidal fashion by a linear mechanical mirror movement. Optical band filters eliminate significant harmonic content being present on a pre-detected optical signal. Sampling of the detected signal energy is performed synchronous to the mechanical mirror position to assure sinusoidal response. The sampled signals are processed to separately determine signal harmonic components attributed to detector non-linearity and multiple laser reflections within the system. The system utilizes at least two measurements at two different laser intensities. An optional third measurement of background radiance may be applied to the first two measurements to enhance accuracy.
摘要:
A fluid quick connector (10) includes first and second coupled housings (26, 28) having aligned bores. A biased shut off valve is mounted in the first housing (26) and has a seal end normally biased into a fluid flow blocking position; but movable away from the seal upon contact with an end form (12) inserted into the bores to a fluid flow enabling position. The first and second housings interact at an adjustable axial interface formed of mating threads to vary the insertion distance of the endform into the first housing after the endform is latched in the first and second housings by a retainer (16) carried in the second housing, to regulate the fluid flow through the quick connector.
