  • Patent number: 9557216
    Abstract: A laser-based spectroscopy system that combines a distance/proximity standoff sensor, a high-repetition rate laser spectroscopy system, and software with a decision-making algorithm embedded in a processing unit which in combination performs selective firing of the laser when the target object is within an interrogation zone. In a related embodiment, the system provides selective sorting of spectroscopic signals based on information from the standoff signal and from information contained in the spectral signals themselves. The laser emission can be actively controlled while keeping the laser firing, thereby preserving the thermal stability and hence the power of the laser; and the standoff sensor information and the spectral information can be combined to determine the proper relative weighting or importance of each piece of spectral information.

  • Patent number: 9506869
    Abstract: A novel device, method and systems disclosed managing the thermal challenges of LIBS laser components and a spectrometer in a handheld structure as well the use of simplified light signal collection which includes a bare fiber optic to collect the emitted light in close proximity to (or in contact with) the test material. In one example embodiment of the handheld LIBS device, a burst pulse frequency is 4 kHz is used resulting in a time between pulses of about 250 ?s which is a factor of 10 above that of other devices in the prior art. In a related embodiment, an active Q-switched laser module is used along with a compact spectrometer module using a transmission grating to improve LIBS measurement while substantially reducing the size of the handheld analyzer.

  • Patent number: 6480646
    Abstract: The travel range is extended for electrostatically actuated micro mirrors used as attenuators, modulators and switches in optical networks by the use of dielectrically coated, preferably with Silicon dioxide, inner surfaces. Oxide charge and oxide capacitance combine to expand the travel range of the mirrors before snap down, at the expense of increased applied bias voltage. This method of travel range extension is preferred over other range extension methods due to its simplicity, reproducibility, and ease of manufacture, as well as benefits of decreased stiction and inhibited electrode shorting. A method for the manufacture of the devices is also disclosed.

  • Publication number: 20020013054
    Abstract: A simple method for making large, uniformly flat electrostatically actuated micro-mirrors for use as variable attenuators and switches in optical networking systems is disclosed. The devices are fabricated by fusion bonding ultra-thin, single crystal silicon wafers to micromachined silicon substrates, forming robust, non-deforming reflective surfaces which are simpler to fabricate than similar devices fabricated by conventional chemical vapor deposition of polycrystalline silicon, which require careful engineering to avoid stress-induced deformation.

  • Patent number: 5843832
    Abstract: A technique of bonding a thin wafer layer to a substrate. The wafer is blown dry using an inert gas to prevent it from being damaged, while still ensuring that it dries completely. The initial bonding is done by orienting crystallographic axes, and then allowing the wafers to adhere to one another slowly. The contact wave is prevented from spreading, by a divider between the two wafers. The wafers are allowed to adhere to one another slowly to form a bond. The bond is strengthened by annealing.

  • Patent number: 5307580
    Abstract: A safety display sign includes a wire post member having spaced apart wire legs extending from a rounded end portion. The wire legs extend through the channels of a corrugated polyethylene sign panel, and project therefrom a sufficient distance to permit secure fixation in the ground. An extruded polyethylene base member is provided with two slotted passages integrally formed at opposite side edges of the base member to receive and grip the wire legs in a unitary assembly which prevents the sign panel from sliding along the length of the wire legs. The polyethylene base is positioned along the length of the wire legs and is urged against the edge of the sign panel by the ground or other supporting surface to secure the sign panel at the top portion of the post.

  • Patent number: 5103582
    Abstract: A display sign in which a panel is supported in cantilever fashion is disclosed. The display sign generally comprises a corrugated panel which may be mounted to a vertical post by a pair of rods which pass through the corrugation channels of the panel and extend through holes in the vertical post. The rods are shaped in a manner to engage the corrugation channels of the panel so as to prevent horizontal sliding or pivoting of the panel relative to the rods.

  • Patent number: 4790092
    Abstract: A display sign has a panel supported on a horizontal arm which is cantilevered on a vertical post. A slot is formed in the horizontal arm and the panel is supported in the slot. The horizontal arm includes a pair of parallelly extending, spaced-apart channel members and a pair of spacers, one of which is inserted at each end of the channel members. The spacers span the channel members and join them together. The slot in the horizontal arm is formed by a gap between the spaced apart channel members. One type of panel which has an upper portion with a width greater than the width of the lower portion is supported in the slot by the spacers. Another type of panel having a lower portion greater in width than in its upper portion and a neck portion with a pair of cutouts is supported in the slot by pivotably mounted plates which engage in the cutouts.
