90944 results about "Laser" patented technology

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow.

Imaging system for vehicle

An imaging system for a vehicle includes a camera module positionable at the vehicle and a control. The camera module includes a plastic housing that houses an image sensor, which is operable to capture images of a scene occurring exteriorly of the vehicle. The control is operable to process images captured by the image sensor. The portions of the housing may be laser welded or sonic welded together to substantially seal the image sensor and associated components within the plastic housing. The housing may include a ventilation portion that is at least partially permeable to water vapor to allow water vapor to pass therethrough while substantially precluding passage of water droplets and / or other contaminants. The housing may be movable at the vehicle between a stored position and an operational position, where the image sensor may be directed toward the exterior scene.

System and method for 3-d projection and enhancements for interactivity

A system projects a user-viewable, computer-generated or -fed image, wherein a head-mounted projector is used to project an image onto a retro-reflective surface, so only the viewer can see the image. The projector is connected to a computer that contains software to create virtual 2-D and or 3-D images for viewing by the user! Further, on projector each is mounted on either side of the user's head, and, by choosing for example a retro angle of less than about 10 degrees, each eye can only see the image of one of the projectors at a give distance up to 3 meters, in this example, from the retro-reflective screen. The retro angle used may be reduced with larger viewing distance desired. These projectors use lasers to avoid the need for focusing, and in some cases there projectors use instead of lasers highly collimated LEO light sources to avoid the need for focusing.

Three-dimensional measurement method and apparatus

The apparatus and method measure the three-dimensional surface shape of a surface without contact with the surface, and without any physical constraint on the device during measurement. The device is a range-sensor or scanner, and in one embodiment is a laser-camera sensor, which has a portable camera and multi-line light projector encased in a compact sensor head, and a computer. The apparatus provides three-dimensional coordinates in a single reference frame of points on the surface. The sensor head does not have to be physically attached to any mechanical positioning device such as a mechanical arm, rail, or translation or rotation stage, and its position in three-dimensional space does not have to be measured by any position-tracking sensor. This allows unrestricted motion of the sensor head during scanning, and therefore provides much greater access to surfaces which are immovable, or which have large dimensions or complex shape, and which are in confined spaces such as interior surfaces. It also permits measurement of a surface to be made by a continuous sweeping motion rather than in stages, and thus greatly simplifies the process of measurement. The apparatus can be hand-held, mounted on any moving device whose motion is unknown or not accurately known, or airborne. The apparatus and method also permit unknown and unmeasured movement of the object whose surface is to be measured, which may be simultaneous with the movement of the range-sensor head.

Radical Reactor with Multiple Plasma Chambers

Two or more plasma chambers are provided in a radical reactor to generate radicals of gases under different conditions for use in atomic layer deposition (ALD) process. The radical reactor has a body with multiple channels and corresponding process chambers. Each plasma chamber is surrounded by an outer electrode and has an inner electrode extending through the chamber. When voltage is applied across the outer electrode and the inner electrode with gas present in the plasma chamber, radicals of the gas is generated in the plasma chamber. The radicals generated in the plasma chamber are then injected into a mixing chamber for mixing with radicals of another gas from another plasma chamber, and injected onto the substrate. By providing two or more plasma chambers, different radicals of gases can be generated within the same radical reactor, which obviates the need for separate radical generators.

Sleep apnea detector system

An apnea monitor and system for treatment includes a detector in a fixed console that projects a detection beam at a sleep surface. The detection beam is reflected off a patient on the surface and return light is analyzed to develop a signal which varies with external motion of the patient's upper body. The motion signals are then fed to a pattern recognizer which identifies breath signals and analyzes them to detect cessation or excessive pauses in breathing, and trigger an alarm or intervention to restore breathing regularity. The monitor includes a laser for generating radiation. The radiation is reflected from the patient and is directed onto a detector. The detector produces output signals corresponding to the impinging reflected light, which are processed by a control element to determine the change of movement, e.g., the breathing rate, of the patient.

A method of forming a conductor in a thin film structure on a semiconductor substrate includes forming high aspect ratio openings in a base layer having vertical side walls, depositing a dielectric barrier layer comprising a dielectric compound of a barrier metal on the surfaces of the high aspect ratio openings including the vertical side walls, depositing a metal barrier layer comprising the barrier metal on the first barrier layer, depositing a main conductor species seed layer on the metal barrier layer and depositing a main conductor layer. The method further includes annealing the main conductor layer by (a) directing light from an array of continuous wave lasers into a line of light extending at least partially across the thin film structure, and (b) translating the line of light relative to the thin film structure in a direction transverse to the line of light. The method of Claim 1 further comprising, prior to the annealing step, depositing an amorphous carbon optical absorber layer on the main conductor layer. The step of depositing an amorphous carbon optical absorber layer includes introducing a carbon-containing process gas into a reactor chamber containing the substrate in a process zone of the reactor, applying RF source power to an external reentrant conduit of the reactor to generate a reentrant toroidal RF plasma current passing through the process zone and applying a bias voltage to the substrate.

High speed parallel molecular nucleic acid sequencing

A method and device is disclosed for high speed, automated sequencing of nucleic acid molecules. A nucleic acid molecule to be sequenced is exposed to a polymerase in the presence of nucleotides which are to be incorporated into a complementary nucleic acid strand. The polymerase carries a donor fluorophore, and each type of nucleotide (e.g. A, T / U, C and G) carries a distinguishable acceptor fluorophore characteristic of the particular type of nucleotide. As the polymerase incorporates individual nucleic acid molecules into a complementary strand, a laser continuously irradiates the donor fluorophore, at a wavelength that causes it to emit an emission signal (but the laser wavelength does not stimulate the acceptor fluorophore). In particular embodiments, no laser is needed if the donor fluorophore is a luminescent molecule or is stimulated by one. The emission signal from the polymerase is capable of stimulating any of the donor fluorophores (but not acceptor fluorophores), so that as a nucleotide is added by the polymerase, the acceptor fluorophore emits a signal associated with the type of nucleotide added to the complementary strand. The series of emission signals from the acceptor fluorophores is detected, and correlated with a sequence of nucleotides that correspond to the sequence of emission signals.
