A phosphor screen for image forming including phosphor material being excitable by light in a wavelength λ1. The phosphor screen receives an optical image from an image forming optical system and produces the optical image at a second wavelength λ2. The phosphor screen includes a phosphor layer comprising the phosphor material. A short-pass reflective coating is positioned on a first side of the phosphor layer. The short-pass reflective coating transmits the wavelength λ1 and reflects the wavelength λ2. A long-pass reflective coating is positioned on a second side of the phosphor layer. The long-pass reflective coating transmits the wavelength λ2 and reflects the wavelength λ1. A first substrate is positioned over the short-pass reflective coating. The first substrate is formed of optically clear and thermal conductive material. A second substrate is positioned over the long-pass reflective coating. The second substrate is formed of long-pass absorptive optical filter material that transmits the wavelength λ2 and absorbs wavelength λ1 from ambient light to prevent the phosphor layer from being excited by the ambient light. The phosphor screen may alternatively be used for a direct-view visual display apparatus. These principles can also be utilized for backlighting and general illumination applications.

A toner comprising:

• • a binder resin which is at least a resin selected from the group consisting of modified polyester resins and unmodified polyester resins; and
  • a colorant; the product toner having a volume-average particle diameter (Dv) to a number-average particle diameter (Dn) ratio (Dv/Dn) ranging from 1.00 to 1.30, and the toner having a shape factor SF-1 ranging from 140 to 200.

A power saving circuit employing visual persistence effect for backlight modules aims to increase electric power at a duty mode to drive lighting units at a read end through driving units, and provide zero or lower electric power at a power saving mode to the lighting units at the rear end. Different lighting units generate light alternately in a first condition time sequence to enable user's eyes to get images. In a second condition time sequence power consumption of the driving units is reduced and user's eyes still can maintain visual sense of the images due to visual persistence effect, thereby electric power can be saved.

An illuminator illuminates a symbol with a low level of illumination in a detection mode of operation to enable an imager to detect the symbol in a working range and in a field of view of the imager in an imaging reader, and also illuminates the symbol with a high level of illumination in a reading mode of operation to enable the imager to read the symbol.

Lighted refrigerated display case with remote light source comprises a closed container with an interior of the container refrigerated to a temperature below 7 C. The container is thermally insulated from ambient, having internal and external walls. A solid fiber optic luminaire is at least partially mounted within the container, having an elongated side-light emitting portion for emitting light from the side of the luminaire onto contents in an interior of the display case. The side-light emitting portion comprises an extractor of light arranged to preferentially extract light from the luminaire and direct the light in at least one radial direction along the length of the side-light emitting portion to at least one target area of said contents along a longitudinal axis of the side-light emitting portion. A light-delivery system provides light to the fiber optic luminaire, having a light source mounted remotely from the interior of the container.

A driving method for driving an LCD panel having a counter electrode and a source line. In a first period, the counter electrode is driven to a potential VCOMH. In a second period, the counter electrode and the source line are short-circuited to a power supply interconnection having a power supply potential VCI. In a third period, the counter electrode is connected to a ground interconnection while the source line is kept to be short-circuited to the power supply interconnection. In a fourth period, the counter electrode is pulled down to a potential VCOML lower than a ground potential In a fifth period, the source line is driven to a potential corresponding to an image data while the counter electrode is kept to the potential VCOML. The electric power consumed in pulling down the counter electrode from a positive potential to a negative potential can be effectively reduced.

A sauna cabin enclosure comprised of two half cabins, one half being smaller than the other, such that one half can fit inside the other and can slide to contract or expand partially or fully, thereby increasing or decreasing the air volume inside and the overall external size. This cabin has infrared heating, full spectrum lighting and a steam generator. When the cabin size is reduced by means of a hand crank or a motor, the air volume inside the cabin is decreased, allowing air temperature to increase proportionally. The cabin can be compressed together to minimize required floor space.

In an apparatus, if it is detected that a condition is met to switch the apparatus from the normal power mode to a power saving mode that consumes less power than the normal power mode, a communication speed for the apparatus to communicate via a network is changed, an authentication process is executed, and the apparatus is switched from the normal power mode to the power saving mode when the authentication process is completed.

An electronic flow measurement device (EFM), for use in conjunction with a flow meter in a pressurized gas line, has a microprocessor and read-only memory (ROM), and calculates and records gas flow rates corrected for variable factors such as gas pressure, temperature, and density. Look-up tables stored in the ROM contain intermediate values calculated in accordance with selected protocols for selected ranges of input variables such as gas temperature, pressure, density, and turbine “K” factors. Based on inputs received from gas temperature and pressure sensors, the EFM selects corresponding intermediate values from the look-up tables, and then uses these values to calculate corrected gas flow rates, using software residing in the EFM. The microprocessor's power consumption is significantly reduced because the use of look-up tables reduces the complexity and extent of calculations that the EFM needs to perform, as compared with performing all required calculations in the EFM.

Lighted display case with remote light source comprises a container having contents for display. A solid fiber optic luminaire is at least partially mounted within the container, having an elongated side-light emitting portion for emitting light from the side of the luminaire onto contents in an interior of the display case.

The portion may be rotatable about its own longitudinal axis. A single side-light emitting portion may be arranged to illuminate a target area on one of its lateral sides, and another target area on another lateral side. A single lamp may provide light to first and second luminaires arranged to illuminate a target area on one of its lateral sides, and another target area on another lateral side.
