The apparatus of the present invention includes a light source for producing a coherent beam of light. A beam splitter is provided for splitting the beam of light into a first, transmitted beam segment and a second, local oscillator beam. A mechanism is provided for frequency shifting the frequency of one or both beam segments and for directing the first beam segment to a target. A remote target for scattering the first beam is provided. A mechanism is provided for combining the scattered first beam segment returning from the target and the second beam segment into a combined beam, and detecting the combined beam. A detector is operative to generate a signal indicative of the crosswind along the path of the directed first beam segment. A mechanism for determining the wind speed normal to the path from the generated signal is also provided.

A laser wax joinery method and apparatus are disclosed. Molded wax segments, such as those used to produce patterns for investment casting, are immobilized relative to one another, with their conforming marginal edges in abutted relationship, on a two axis rotatable tilt table. A laser beam of controllable energy density scans the edges of the wax segments, forming therealong a wax weld pool that, while molten, is maintained generally horizontal by rotation of the tilt table. The laser beam's energy density is modulated to correspond with the varying thickness of the edges to be joined. A laser beam delivery system includes a process robot and a lens and mirror system for directing the beam generally vertically toward the surface of the wax segments. Shrinkage by wax dripping or filler vaporization is avoided by precisely controlling the energy density adjacent the weld joint. By coordinating the operation of the tilt tables and the laser beam delivery system under the programmable control of a master controller, it is possible repeatably to produce strong, smooth, uninterrupted weld joints. In modifications, the wax weld pool is controlled by preparatory covering of the surface adjacent the abutted edges with a fluid-resistant, conformable, and laser beam-transmissive polyethylene, or thermally conductive metal foil, material that, while transmitting, or conducting, a substantial portion of the laser energy to the wax segments, prevents loss of wax by dripping. In another modification, the weld pool is controlled by multiply scanning the abutted edges at a reduced energy density.

A home energy monitoring and control system for monitoring the electrical energy usage of a plurality of appliance loads. The system includes an energy monitor unit for each appliance load which plugs into a standard AC wall outlet and monitors power consumption and also has a power line transmitter/receiver for communicating with a master control station. The master control station receives energy usage data from each of the monitor units and stores the data for display in various user-selectable formats.
