摘要： Attaching an attachment surface of an electrically conductive workpiece to an electrically conductive support surface is described. In one aspect, a biasing force is distributed at least partially around a weld region of the workpiece to urge the attachment surface of the workpiece against the support surface in a way which at least resists welding induced movement of the workpiece relative to the support arrangement. An electrode arrangement, having an electrode tip, contacts the workpiece to provide for substantially compliant movement of the electrode tip against the weld region in directions that are parallel to the support surface. In another aspect, a combined manipulation/welding arrangement is supported for controlled movement with a free end configured for engaging the workpiece to bias the workpiece against the support surface to manipulate the workpiece against the surface and to conduct an electrical current, while holding the workpiece, for welding to the support surface.

摘要： 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.

摘要： An apparatus for analyzing, identifying or imaging a target including an integrated dual laser module coupled to a pair of photoconductive switches to produce CW signals in the range of frequencies from 100 GHz to over 2 THz focused on and transmitted through or reflected from the target; and a detector for acquiring spectral information from signals received from the target and using a multi-spectral homodyne process to generate an electrical signal representative of some characteristics of the target with resolution less than 250 MHz. The photoconductive switches are activated by laser beams from the dual laser module. The lasers in the module are tuned to different frequencies and have two distinct low frequency identification tones respectively that are used in conjunction with a stable optical filter element to permit precise determination of the offset frequency of the lasers.

摘要： An apparatus for analyzing, identifying or imaging an target including first and second laser beams coupled to a pair of photoconductive switches to produce CW signals in one or more bands in a range of frequencies greater than 100 GHz focused on and transmitted through or reflected from the target; and a detector for acquiring spectral information from signals received from the target and using a multi-spectral heterodyne process to generate an electrical signal representative of some characteristics of the target. The lasers are tuned to different frequencies and a frequency shifter in the path of one laser beam allows the terahertz beam to be finely adjusted in one or more selected frequency bands.
