  • Patent number: 6956500
    Abstract: An inexpensive energy monitoring device and method for measuring energy usage and power costs in real time. The invention can include an external type digital battery powered camera that can be mounted away from and adjacent to the outdoor utility meter on a rotatable arm, which can send data signals to remote locations indoors using wireless such as an RF signal to a detector/display inside the residence. The indoor unit can be programmed to display desirable energy status information to a home owner on power usage and power costs on a daily bases, monthly bases, and yearly bases so that the home owner can budget energy usage and energy costs as needed. A shield can also be used with device and method for shielding power meters from adverse weather conditions.

  • Publication number: 20040105261
    Abstract: A lighting fixture for producing a beam of light having a prescribed luminous flux spectrum. In one example, the lighting fixture comprises a plurality of groups of light-emitting devices, each such group configured to emit light having a distinct luminous flux spectrum, and a controller configurable to supply selected amounts of electrical power to the plurality of groups of light-emitting devices, such that the groups cooperate to produce a composite beam of light having a prescribed luminous flux spectrum.

  • Publication number: 20030133292
    Abstract: Methods and apparatus for generating and modulating white light illumination conditions. Examples of applications in which such methods and apparatus may be implemented include retail environments (e.g., food, clothing, jewelry, paint, furniture, fabrics, etc.) or service environments (e.g., cosmetics, hair and beauty salons and spas, photography, etc.) where visible aspects of the products/services being offered are significant in attracting sales of the products/services. Other applications include theatre and cinema, medical and dental implementations, as well as vehicle-based (automotive) implementations. In another example, a personal grooming apparatus includes one or more light sources disposed in proximity to a mirror and configured to generate variable color light, including essentially white light, whose color temperature may be controlled by a user.

  • Publication number: 20030057890
    Abstract: Provided are methods and systems for controlling the conversion of data inputs to a computer-based light system into lighting control signals. The methods and systems include facilities for controlling a nonlinear relationship between data inputs and lighting control signal ouputs. The nonlinear relationship may be programmed to account for varying responses of the viewer of a light source to different light source intensities.

  • Publication number: 20030057887
    Abstract: An embodiment of the invention is a system for generating control signals. The system may allow a user to generate an image, representation of an image, algorithm or other effect information. The effect information may then be converted to lighting control signals to be saved or communicated to a networked lighting system. An embodiment of the invention may enable the authoring, generation and communication of control signals such that an effect is generated in a space or area. An embodiment of the invention may provide systems and methods for the control of a plurality of lighting devices in an environment.

  • Publication number: 20020176259
    Abstract: An illumination system according to the principles of the invention may include a first LED and a carrier material. The carrier material may be comprised of plastic, synthetic material, polymer, latex, rubber or other material. The carrier material may also contain a phosphor, fluorescent material, organic fluorescent material, inorganic fluorescent material, impregnated phosphor, phosphor particles, phosphor material, YAG:Ce phosphor, or other material for converting electromagnetic radiation into illumination or visible light. The illumination system may also have a housing wherein the housing has an open end. The first LED may be arranged to project emitted light through the open end and the carrier material may be cooperatively arranged with the housing such that the emitted light from the first LED is projected through the carrier material.

  • Patent number: 6100540
    Abstract: A laser displacement measurement system including a radiation source for transmitting radiation to a target, an R.F. transmitter oscillator for modulating the amplitude of the radiation at a first frequency, a detector for sensing the radiation reflected from the target, an R.F. local oscillator for providing an R.F. signal at a second frequency, a first mixer circuit, responsive to the oscillators for providing a local I.F. signal which is the difference between the first and second frequencies, a second mixer circuit, responsive to the detector and the R.F. local oscillator, for providing a reflected I.F. signal which is the difference between the second frequency and the modulation frequency of the reflected radiation, and a phase detector, responsive to the local and reflected I.F. signals, for detecting a first phase difference between the signals representative of the distance of the target.

  • Patent number: 6049297
    Abstract: A digital phase measuring system and method for measuring the phase difference between two signals including generating quadrature clock signals for a first reference signal, converting a second measured signal from analog to digital form by sampling the second measured signal using the quadrature clock signals to produce quadrature cartesian samples of the measured signal, and converting the quadrature cartesian samples to polar coordinates to define the polar phase coordinate representative of the phase difference between the two signals.

  • Patent number: 5997155
    Abstract: A method and apparatus for projecting a uniform projection of light by using a diffusive optic and non-imaging optic to receive light beams and uniformly distribute the light beams on a target. The uniform distribution of light diverges according to a pre-designed angle. The device allows for the use of multiple light sources which may be remotely located from the projection device. The projection device may be portable.
