摘要:
A method and apparatus for drug product tracking (or other pharmaceutical, health care or cosmetics products, and/or the packages or containers they are supplied with) using diffraction grating-based encoded optical identification elements 8 includes an optical substrate 10 having at least one diffraction grating 12 disposed therein. The grating 12 has one or more collocated pitches Λ which represent a unique identification digital code that is detected when illuminated by incident light 24. The incident light 24 may be directed transversely from the side of the substrate 10 (or from an end) with a narrow band (single wavelength) or multiple wavelength source, and the code is represented by a spatial distribution of light or a wavelength spectrum, respectively, or a combination thereof. The encoded element 8 may be used to label any desired item, such as drugs or medicines, or other pharmaceutical or health care products or cosmetics. The label may be used for many different purposes, such as for sorting, tracking, identification, verification, authentication, anti-theft/anti-counterfeit, security/anti-terrorism, or for other purposes. In a manufacturing environment, the elements 8 may be used to track inventory for production information or sales of goods/products. Such labeling provides product identification at the pill or liquid medicine level, which provides traceability of these products to their manufacturer, thereby reducing counterfeit products in the marketplace. Also, the elements 8 may be incorporated into a film, liquid, coating or adhesive tape at attached to the product package.
摘要:
A combination kit for the treatment of malaria caused by Plasmodium vivax (P. vivax) having individual doses of an anti-malarial agent, 3-[1-[[4-[(6-methoxy-8-quinolinyl)amino]pentyl]amino]ethylidene]-dihydro-2(3H)-furanone (I) in the form of capsules; individual doses of the anti-malarial agent, chloroquine in the form of tablets; and instruction material for the administration of the two anti-malarial drugs. The combination kit is particularly suited for a 6 days treatment regimen where the treatment is rendered by five tablets containing 500 mg of chloroquine phosphate (equivalent to 300 mg base), three to be taken on day one and one each on days two and three; and five capsules containing 25 mg of 3-[1-[[4-[(6-methoxy-8-quinolinyl)amino]pentyl]amino]ethylidene]-dihydro-2(3H)-furanone (I), one each to be taken on days two to six.
摘要:
An optical spectrum analyzer (OSA) 10 sequentially or selectively samples (or filters) a spectral band(s) 11 of light from a broadband optical input signal 12 and measures predetermined optical parameters of the optical signal (e.g., spectral profile) of the input light 12. The OSA 10 is a free-space optical device that includes a collimator assembly 15, a diffraction grating 20 and a mirror 22. A launch pigtail emits into free space the input signal through the collimator assembly 15 and onto the diffraction grating 20, which separates or spreads spatially the collimated input light, and reflects the dispersed light onto the mirror 22. A λ/4 plate 26 is disposed between the mirror 22 and the diffraction grating 20. The mirror reflects the separated light back through the λ/4 plate 26 to the diffraction grating 20, which reflects the light back through the collimating lens 18. The lens 18 focuses spectral bands of light (λ1–λN) at different focal points in space. One of the spectral bands 11 is focused onto a receive pigtail 28, which then propagates to a photodetector 30. A pivoting mechanism 34 pivots the diffraction grating 20 or mirror 22 about a pivot point 36 to sequentially or selectively focus each spectral band 11 to the receive pigtail 28. A position sensor 42 detects the displacement of the diffraction grating 24 or mirror.

摘要:
A reconfigurable optical interleaver/deinterleaver device combines/separates a pair of optical input signals from and/or to an optical WDM input signal. The interleaver device includes a spatial light modulator having a micro-mirror device with a two-dimensional array of micro-mirrors that flip between first and second positions in a “digital” fashion in response to a control signal provided by a controller in accordance with a switching algorithm and an input command. A pair of collimators, diffraction gratings and Fourier lens collectively collimate, separate and focus the optical input channels and optical add channels onto the array of micro-mirrors. Each optical channel is focused on a plurality of micro-mirrors of the micro-mirror device, which effectively pixelates the optical channels.

An overlay for a sectional garage door extends between adjacent panel sections of the door. The overlay has a plurality of members made of extruded polystyrene. The overlay members extending from one section of the door to an adjacent section are cut along the centerline between door sections to allow the door to open and close and provide an aesthetically pleasing and professional appearance without gapping.

A composition including an optical substrate removably attached to an item. At least a portion of the substrate has a diffraction grating embedded therein or thereon. The grating has a resultant refractive index variation at a grating location. The grating provides an output optical signal indicative of a code when illuminated by an incident light signal.
摘要:
An optical channel monitor is provided that sequentially or selectively filters an optical channel(s) 11 of light from a (WDM) optical input signal 12 and senses predetermined parameters of the each filtered optical signal (e.g., channel power, channel presence, signal-noise-ratio). The OCM 10 is a free-space optical device that includes a collimator assembly 15, a diffraction grating 20 and a mirror 22. A launch pigtail emits into free space the input signal through the collimator assembly 15 and onto the diffraction grating 20, which separates spatially each of the optical channels 11 of the collimated light, and reflects the separated channels of light onto the mirror 22. A λ/4 plate 26 is disposed between the mirror 22 and the diffraction grating 20. The mirror reflects the separated light back through the λ/4 plate 26 to the diffraction grating 20, which reflects the channels of light back through the collimating lens 18. The lens 18 focuses each separated channel of light (λ1-λN) at a different focal point in space. One of the optical channels 11 is focused onto a receive pigtail 28, which then propagates to a photodetector 30. A pivoting mechanism 34 pivots the diffraction grating 20 or mirror 22 about a pivot point 36 to sequentially or selectively focus each optical channel 11 to the receive pigtail 28. A position sensor 42 detects the displacement of the diffraction grating 24 or mirror.
