Abstract: Coagulation spinning produces structures such as fibers, ribbons, and yarns of carbon nanotubes. Stabilization, orientation, and shaping of spun materials are achieved by post-spinning processes. Advantages include the elimination of core-sheath effects due to carbonaceous contaminants, increasing mechanical properties, and eliminating dimensional instabilities in liquid electrolytes that previously prohibited the application of these spun materials in electrochemical devices. These advances enable the application of coagulation-spun carbon nanotube fibers, ribbons, and yarns in actuators, supercapacitors, and in devices for electrical energy harvesting.

Abstract: A method and apparatus for brightening and dimming a brake light of automotive vehicle for enhanced display indication of braking includes a pulse width modulation unit to be electrically connected to a brake lamp for sequentially modulating the supply energy to the lamp to generate a brightening and dimming of the lamp. A time extent of the modulation is detected so that the modulation can be stopped after a preselected time period and the light will be continually on as in a conventional braking operation. After the brake is released by the operator, a second preselected time period for locking out the sequential interrupting is timed down, for avoiding repetitive flashing during stop-and-go traffic.

Abstract: In the present invention, several timer functions (e.g. delay on make, delay on break, recycle, single shot, etc.) are expressed in terms of a series of timer subfunctions, and code segments are developed for each identified subfunction. A program of a timer is established to include a plurality of subfunction code segments and a subfunction ordering table for determining the ordering of execution for the subfunction code segments. The ordering of subfunctions of the subfunction ordering table may be selectable in accordance with a model number input received at a program builder system adapted for use in programming the programmable timer. In one embodiment, the programming method provides for reprogramming of a timer including a control circuit having a one-time programmable processor.

Abstract: The present invention is a timer module system including a timer module, program builder system for developing programs for loading into the timer module, and a model number data page for use in selecting the appropriate program for loading into the timer module. The timer module includes circuit elements configured for control by a timer processor system so that various timer functions, time delay functions, and time delay settings are realized by appropriate programming of the timer processor system. The program builder system includes a builder processor system having a program for developing a timer operating program in response to a user-input model number command selected using the model number data page. A breakable communication link is provided between the timer module and the program builder system to facilitate the transmission of developed timer operating programs from the program builder system to the timer module.

Abstract: Porous solid bodies, especially carbon bodies, are densified by chemical vapor deposition by establishing a thermal gradient within the body, thermally decomposing a gaseous precursor so deposit an electrically and thermally conductive deposit (e.g. carbon) within the body, and shifting the thermal gradient toward the lower temperature zone as deposition proceeds, by means of induction heating.

Abstract: A sensor for use in an optical temperature detector system having a birefringent element made of a single crystal metal oxide plate. A broad band light spectrum is transmitted through a first linear polarizing element to create a linearly polarized wave. The linearly polarized wave on passing through the single crystal metal oxide plate decomposes into first and second orthogonally polarized waves. Propagation of the linearly polarized wave through the birefringent single crystal metal oxide plate introduces a temperature dependent phase shift between the two waves. Thereafter, a second linear polarizer combines the first and second orthogonally polarized waves to create a modulated light spectrum having a fringe pattern, the fringe pattern being a function of the current temperature experienced by said birefringent element.

Abstract: This invention provides birefringent optical waveguide structures of crystalline aluminum garnet of a high refractive index which are clad with crystalline aluminum garnet of a lower refractive index. Due to predetermined lattice mismatch between garnet substrate and cladding layer, strain is induced which causes a stress with resultant birefringence in the waveguide layer. When linearly polarized light enters such stressed waveguide in certain orientations, the linear polarization will be preserved by the stress-induced birefringence. These birefringent clad waveguides can be in the form of slabs, channels, ribs, or any of the typical optical waveguide structures. They are useful at high temperature.

Abstract: Rotational displacement of the birefringent lasing medium in a lasing cavity containing a polarizing element varies the spectral width of the generated laser light. The combination in a lasing cavity of a birefringent lasing medium, a polarizing element, a tuning element and a birefringent compensator permits output of narrow bandwidth spectrally tuned laser light continuously over the total gain bandwidth of the lasing medium by rotating the lasing medium, tuning to desired wavelength, and adjusting the birefringent compensator to optimize output of laser light.

Abstract: Optical waveguides suitable for use in high temperature environments are constructed of a waveguiding body composed of a first crystalline aluminum garnet, which is clad with an epitaxially deposited layer of a second crystalline aluminum garnet.
