    • A low voltage differential signaling (LVDS) transmitter receives a data signal, a data invert signal and a plurality of logic signals. The LVDS transmitter includes a first-stage differential signaling transmitting circuit and a second-stage differential signaling transmitting circuit. The first-stage differential signaling transmitting circuit receives the data signal and the data invert signal and has a first output terminal and a second output terminal. The second-stage differential signaling transmitting circuit is controlled by the logic signals, and has a third output terminal and a fourth output terminal respectively connected to the first output terminal and the second output terminal, so as to generate a needed pre-emphasis signal. When no pre-emphasis signal needs to be generated, the second-stage differential signaling transmitting circuit is controlled to be in disabled state.

    • An optical assembly includes a light path and at least one optic to be positioned in the path. A support arrangement supports the optic having a foot arrangement including at least one foot that receives a direct manipulation with the foot slidingly engaged against a support surface to move the optic relative to the light path. Movement of the foot may move the optic along a predetermined path. The foot defines a footprint for engaging the support surface and receives the direct manipulation in a way which changes the footprint on the support surface to move the optic responsive to changes in the footprint. A movement arrangement may selectively bias the foot against the support surface during a movement mode, intended to permit movement of the foot against the support surface, and in a locked mode, intended to lock the foot against the support surface.

    • An arrangement is provided including an electrode extending to an electrode tip for contacting a workpiece. A welding configuration of the electrode tip is established by exposing the electrode tip to a selected welding environment for use in forming a weld having a target set of weld parameters. An electrode passage is defined in a biasing force arrangement supporting at least a portion of the length of an elongated, flexible electrode and to limit lateral movement sufficient to transfer at least a portion of a resilient force to the electrode tip so that the tip resiliently contacts the weld region. The electrode passage limits induced lateral flexing to an extent which transfers an amount of the resilient force to the first end portion of the electrode that is sufficient to provide for formation of a weld between the support arrangement and the workpiece.
