A first type of suspended platform balance used a partly symmetrical mass carrier.

The observation optical path (1) can be partially constructed in a manner symetrical to the illumination optical path (1) (indicated with dotted lines).

The pump arrangement (1) comprises at least one high-pressure housing at least partially symmetrical about a center axis (20) and at lest one membrane (3) disposed in the high-pressure housing (2).

The filtering is localized, non-symmetrical, and at least partially compensatory of the smear.

A cutting tool (10) has a part-elliptical symmetrical cutting edge (11).

A first type of suspended platform balance used a partly symmetrical mass carrier.

The metering gate (1010) provides a less tortuous and more symmetrical flow path when the gate is partially open, but provides a relatively straight downward flow channel allowing full flow when the gate is fully open.

The symmetrical two-wire line (42) is at least partially encapsulated within a central portion of a closed pipe (40) comprising a wall (44) that insulates the symmetrical two-wire line from the outer medium.

The observation optical path (1) can be partially constructed in a manner symetrical to the illumination optical path (1) (indicated with dotted lines).

If the sensor deforms, due to a specifically symmetric positioning of the first and second means, the effect of the displacement is at least partly eliminated.

The equalizer (156), which is connected to the imager (130), receives image data and at least partially compensates for the aberration caused by the rotationally symmetric lens assembly (110).

A first symmetric key and a second symmetric key different than the first symmetric key are generated at a first location.

Further the elastomeric body (6) has an internal cavity (17) which is symmetric about the centre axis and extends at least partially between the end members.

The push-pull circuit includes an active pull-up device that is enabled during a first push-pull mode of operation for providing a high data rate.

The invention describes an acoustic balanced-unbalanced (balun) or balanced-balanced thin-film BAW filter based on lateral acoustic coupling.
