  • High speed optoelectronic subassembly and package for optical devices
    Patent number: 7206518
    Abstract: A high speed optoelectronic subassembly in an optoelectronic package is disclosed that includes a dielectric support having a first electrical trace on a surface thereof and a dielectric member mounted on the surface of the support having a second electrical trace thereon. The support extends laterally a distance greater than the member to form a shelf. A dielectric step is positioned on the shelf abutting an end of the member and a laser is positioned on the shelf adjacent the step so as to be light accessible external to the subassembly. The laser and the step have surfaces equal in height and cooperate to provide a mounting platform. A resistive element is positioned on the mounting platform and electrically connected to the laser, the resistive element and laser being electrically externally accessible through the traces.

  • Fluid heating system
    Patent number: 7206506
    Abstract: A fluid heating system includes a fluid supply conduit, a hot fluid conduit, and a fluid heating tube assembly. The fluid heating tube assembly includes an inlet coupling coupled to the fluid supply conduit, an outlet coupling coupled to the hot fluid conduit, and at least one fluid heating tube coupled between the inlet coupling and the outlet coupling. The at least one fluid heating tube includes a tube formed of heat conducting material, a dielectric coating permanently bonded on an outer surface of the tube, and a resistive layer permanently bonded on the dielectric coating. A power distributor is coupled to the fluid heating tube assembly and coupleable to a power source. A switch is coupled between the power distributor and the fluid heating tube assembly to control current flow from the power distributor to the at least one fluid heating tube.

  • Semiconductor device with inductive component and method of making
    Patent number: 7202152
    Abstract: An integrated circuit (10) includes a semiconductor substrate (11) that has a top surface (32) for forming a dielectric region (14) with a trench (40) and one or more adjacent cavities (16). A conductive material such as copper is disposed within the trench to produce an inductor (50). A top surface (49) of the inductor is substantially coplanar with an interconnect surface (31) of the semiconductor substrate, which facilitates connecting to the inductor with standard integrated circuit metallization (57).

  • Light/electric probe system and method
    Patent number: 7198633
    Abstract: A stimulation probe system includes a light integrating chamber with a reflecting inner surface. A plurality of LEDs is mounted to introduce emitted light into the light integrating chamber. Each LED produces a different wavelength of light with the plurality of LEDs producing a range of light wavelengths. A hand-held probe includes a circular opening in communication with the chamber positioned to supply light from the chamber to the surface of a body. Electrical circuitry is programmable to activate one or more of the LEDs to produce substantially any light wavelength in the range of light.

  • Highchair
    Patent number: 7185949
    Abstract: A highchair includes a seat attached to a frame having a first periphery defining a first footprint of the frame. Wheels are attached to the frame adjacent to the first periphery for providing wheeled movement of the frame over a surface. The first periphery of the frame bounds a receiving area underlying the frame within the first footprint of the frame. An arresting fixture is located in the receiving area and has a second periphery defining a second footprint of the arresting fixture within the first footprint of the frame. The arresting fixture is mounted to the frame for movement in reciprocal directions relative to the frame between a first position toward the frame, and a second position away from the frame for engagement with the surface for arresting the frame from wheeled movement over the surface.

  • Beveled insert for facilitating coupling pipes
    Patent number: 7182372
    Abstract: An annular beveled insert for enhancing the insertion of a plain end of a pipe into a mating belled end of a pipe, the insert including an annular main body portion having a substantially flat surface and a beveled opposed surface. The annular main body portion has inner and outer diameters approximately equal to inner and outer diameters, respectively, of the plain end of the pipe. An outwardly directed flange extends from the annular main body portion around a periphery and has an outer diameter greater than the outer diameter of the plain end of the pipe. The flange is sufficiently flexible so that it bends into an angle of approximately ninety degrees with the flat surface of the annular main body portion and aids the main body portion in masking the plain end of the pipe as it passes through the annular gasket.

  • Roll-forming apparatus
    Patent number: 7178456
    Abstract: Roll-forming apparatus is provided together with a conveyor system utilized to transport raw dough rolls. A stop gate is movably positioned in the path of the rolls and, when placed in an interfering position, temporarily stops the rolls while the rolls maintain sliding contact with the conveyor. An imprinter is positioned above the conveyor and adjacent the stop gate. The stop gate is subsequently moved to a noninterfering position to permit the rolls to pass to the imprinting drums where the rolls are formed into a desired shape.
