A display screen magnifier is controllable by a user to magnify selected portions of a desktop including windows open on the screen. A moveable magnifier frame is provided, within which a magnified image is presented. The magnified image corresponds to screen content located within a magnification region underlying the magnifier frame, magnified to a set level of magnification. In one embodiment, the magnification region is moveable relative to the magnifier frame, in relation to movement of the magnifier frame on the display screen. Such relative movement can be used to avoid a potentially disorienting edge condition that arises when a magnifier frame reaches an edge of the display screen and stops, while its associated magnification region continues to pan. In another embodiment, the cursor of a user input device is moveable across the screen display into and out of the magnification region. When the position of the cursor falls within the magnification region, the cursor appears within the magnified image presented within the magnifier frame. A related feature avoids the potentially disconcerting effect of cursor disappearance as a pointing device cursor passes into a “lens shadow” defined between the magnification region and the magnifier frame.

A mirror for facilitating appearance related functions includes a circular ring-shaped frame holding therein back-to-back reflective mirror plates having different magnification factors, e.g. 1× and 5×, each plate having a circular central imaging reflective area and an outer concentric light transmissive window area. Continuously rotatable pivot joints support the frame between opposed arms of a yoke protruding upwardly from a stanchion and base for placement on a table, or an arm and wall bracket for mounting on a wall, enabling the frame to be rotated to interchangeably orient 1× and 5× mirror plates in a forward facing use position. A ring-shaped, printed circuit board with circumferentially spaced apart light emitting diodes (LED's) protruding radially outwards of an outer circumferential edge of the board is located between inner facing surfaces of the mirror plates. Illumination of objects in front of the mirror plates is effected by direct LED rays emitted forwardly through the light transmissive windows, and intensified by indirect LED rays reflected from reflective inner facing surfaces of the mirror plates. Electrical power is supplied to the LED's from a battery power supply in the base of the mirror by electrically conductive pins which protrude radially outwards from opposite sides of the frame, the pins being rotatably supported in electrically conductive cups located in opposed arms of the yoke, the cups being connected to the power supply via wires disposed through the yoke arms and stanchion to the power supply.

A light source device for radiating a stimulated emission from a semiconductor laser to outside via a multiple scattering optical system, which system has a first region located adjacent to the semiconductor laser and a second region that abuts on the first region and reaches the outside. The first region contains scatterers at a higher density than the second region does. The light source device has an amount of near-field pattern speckles σPAR of 3×10−3 or more. The second region may have a lens portion as a magnifier for at least a principle part of a secondary planar light source formed at an interface between the first and second regions.

A method and system that uses a computer system as a telemicroscope. A plurality of images of a specimen are captured (Digital camera scanner video camera). The images correspond to the entire specimen and a plurality of segments of the specimen (Multiple linked images). The high-resolution images corresponding to said plurality of segments have different magnification levels and locations (magnifying glass effect); a linking map is generated between said images (Multiple linked images). The linking map comprises information regarding geographical location of the images in relation to the specimen's structure (Image geographical measurement); and images and said linking map are transmitted to a remote user via a computer network thereby allowing the user to view the images with different magnification levels without compromising in image clarity (Computer station one and computer station two). The transmitted images are viewed in a dynamic manner, permitting the user to navigate, enlarge, measure, compare, annotate and exam the digitized images on a virtual slides displayed on a computer screen (Image analysis measurement). The operation of the system closely mimics that of a light microscope.

A method and an apparatus for laser marking indicia in the volume of gemstones such as diamonds, the indicia being made up of a plurality of microscopic dot-shaped marks whose build-up can be initiated by exposing naturally-occurring internal defects or impurities in the volume of a gemstone to a tightly focused train of laser pulses. Authentication data is encoded in the gemstone from the relative spatial arrangement of the dot-shaped marks that form the indicium. Taking advantage of the presence of otherwise invisible defects in the gemstone allows for inscribing indicia with laser pulses carrying energies substantially lower than the threshold energy required for inscribing in the volume of a perfect gemstone material. The marking process is then much less susceptible to inflict damages to the surface of the gemstone, and the marking can be performed using a broad variety of femtosecond laser systems. The dot-shaped marks engraved at a depth below the surface of a gemstone can be made undetectable with the unaided eye or with a loupe by limiting their individual size to a few micrometres, while devising indicia made up of only a few marks. As a result, the marking does not detract from the appearance and value of the gemstone. The procedure for laser marking accounts for the random spatial distribution of the defects present in natural gemstones as well as for their strongly localized character. The presence of an indicium can be detected by using a dedicated optical reader that can be afforded by every jewellery store.

A mirror includes a frame holding back-to-back a pair of reflective mirror plates having different magnification factors, each plate having a reflective central area and an outer concentric light-transmissive window area. Rotatable pivot joints supporting the frame between opposed arms of a support yoke and enable the frame to be rotated to orient a selected plate in a forward-facing use position. A hoop-shaped printed circuit board having circumferentially spaced apart light emitting diodes (LED's) protruding therefrom is located between inner facing surfaces of the mirror plates. Objects in front of a mirror plates are illuminated by direct LED rays emitted forwardly through the window areas and by indirect LED rays reflected from reflective inner facing surfaces of the mirror plates, and from the forward facing surface of a movable reflector ring within the frame which falls rearward when the frame is rotated.

A portable travel mirror device includes a base, a handle pivotably mounted to the base, and a dual mirror assembly mounted to the handle which is pivotable and telescopically extendable between compact transport and upright use configurations, and includes a circular primary mirror frame holding a magnifying mirror encircled by a ring-shaped lamp energized by a power source within the base, and overlain by a diffuser ring.

Sunlight is localized at a solar cell by means of a lens in conjunction with a solar energy trap with very low losses. The lens is a standard magnifying lens which concentrates the sunlight to a spot which is a small percentage of the total area of the lens. The lens is fixed at a tilt angle which is in accordance with the latitude of the site of the solar collection. The daily arc of the sun across the face of the lens produces a smooth arc path of the spot in three dimensional spaces. At or near the smooth arc in space, a guide which may be a secondary mirror surface or an opening guides the light into a solar trap. The solar trap is a fully mirrored enclosed space which permits light to enter but not leave the trap. The light in the trap is guided to a solar cell within the trap with reflected and scattered light being absorbed by the solar cell.

A computer dynamic cylindrical display provides a natural scrolling capability, giving the appearance of a much larger display in a very small size. The display encloses the electronics of the device and contains a simple weighted cam that senses roll (using rotation sensor much like in a mouse). When the cylinder is placed on a flat surface and rolled up and down, the pixel display scrolls in correspondence with the rolling movement, giving the visual feel of rolling a cylindrical magnifying glass across a finely printed document. A "snap-to" scrolling algorithm makes it easier for the user to stop right on the center of a line of text. Parallax algorithms compensate for the cylindrically wrapped text making it appear flatter. Twisting the cap adjusts the angle of presentation for when the user is not looking straight down onto the display. A touch sensitive overlay allows the user to select menu items or hypertext links as the display "rolls over" that line of text. The display also works without a flat surface (although not as naturally) by turning it while holding it in the air.

An electron beam apparatus having a longer life time of cathode, and allowing a plurality of electron beams to be arranged adequately around an optical axis and five or more electron beams to be formed from a single electron gun. The electron beams emitted from a cathode made of ZrO / W (tungsten zirconium oxide) or a cathode made of carbide of transition metal to the off-optical axis directions may be converged on a sample to scan it. The apparatus includes a plate for reducing a vacuum conductance defined between the electron gun chamber side and the sample side, and apertures are formed through the plate at locations offset from the optical axis allowing for the passage of the electron beams. In order to evaluate a pattern on the sample, the electron beam emitted from the electron gun is incident to the sample surface via an objective lens. The objective lens is composed of a flat electrode having an aperture centered on the optical axis and placed in parallel with the sample surface and an electromagnetic lens including a gap formed in a side facing to the sample. Further, in order to inspect a mask, spacing among a plurality of electron beams after having passed through the mask are extended by a magnifying lens and thus widely spaced electron beams are then converted into optical signal in a scintillator.
