    摘要: A micro electromechanical system (MEMS) broad band incandescent light source includes three layers: a top transmission window layer; a middle filament mount layer; and a bottom reflector layer. A tungsten filament with a spiral geometry is positioned over a hole in the middle layer. A portion of the broad band light from the heated filament is reflective off the bottom layer. Light from the filament and the reflected light of the filament are transmitted through the transmission window. The light source may operate at temperatures of 2500 K or above. The light source may be incorporated into an on board calibrator (OBC) for a spectrometer.

The infrared emitter/detector comprises a single crystal semiconductor, photonic band gap structure which functions both as an infrared emitter, a narrow-band filter, and as a broad-band infrared bolometer detector to exert wavelength control directly on the active element emitter/detector surface using the periodic symmetry of the photonic band gap structure to produce narrow wavelength “forbidden” optical transmission bands or modes to sense the presence of a specified substance in the environment. A system and method for sensing specific substances using the optical infrared emitter/detector of this invention in a sensor device is also provided. Finally, a method of manufacturing the infrared emitter/detectors of the present invention is also provided.

    摘要: In an embodiment, a communications device exchanges, between first and second access terminals, higher priority data in association with a communication session of a first type and also lower priority data in association with a communication session of a second type. If the communications device determines a transition of the first access terminal to a lower data-rate environment, the communication device reduces a size of data packets exchanged between the first access terminal and an application server for the communication session of the second type. If the communications device determines an upcoming data packet is a low-data packet (e.g., a silence packet), the low-data packet is suppressed. If the communications device determines that the first access terminal has attempted transmission of a set of last or near-last data packets in the sequence, the communications device re-transmits the set of last or near-last data packets without waiting for ACKs.

    摘要: A noninvasive analyzer apparatus and method of use thereof is described using a sample mapping phase to establish one or more analyzer/software parameters used in a subsequent individual and/or group specific data collection phase. For example, in the sample mapping phase distance between incident and collected light is varied as a function of time for collected noninvasive spectra. Spectra collected in the sample mapping phase are analyzed to determine a physiological property of the subject, such as dermal thickness, hydration, collagen density, epidermal thickness, and/or subcutaneous fat depth. Using the physiological property or measure thereof, the analyzer is optically reconfigured for the individual to yield subsequent spectra having enhanced features for noninvasive analyte property determination. Similarly, in the mapping and/or collection phase, the incident light is varied in time in terms of any of: sample probe position, incident light solid angle, incident light angle, depth of focus, energy, and/or intensity.

    摘要: In an embodiment, an access terminal includes at least first, second and third functional layers, whereby the first functional layer (e.g., a MAC layer) attempts to a data packet on behalf of the third functional layer (e.g., an application-layer) to an application server via a serving network. If the first functional layer receives an ACK that the serving network has received the data packet, the third functional layer is notified of the ACK. If the first functional layer determines the attempt to transmit the data packet to the serving network has failed, the third functional layer is notified of the transmission failure. In another embodiment, during set-up of a traffic channel (TCH) for a communication session, the access terminal transmits a message to the application server over a signaling port that includes both application-layer and transport-layer connection information to facilitate set-up of a data port for the communication session.

    摘要: Monocrystalline semiconductor lattices with a buried porous semiconductor layer having different chemical composition. Also monocrystalline semiconductor superlattices with a buried porous semiconductor layers having different chemical composition than that of its monocrystalline semiconductor superlattice. Lattices of alternating layers of monocrystalline silicon and porous silicon-germanium have been produced. These single crystal lattices have been fabricated by epitaxial growth of Si and Si-Ge layers followed by patterning into mesa structures. The mesa structures are stain etched resulting in porosification of the Si-Ge layers with a minor amount of porosification of the monocrystalline Si layers. Thicker Si-Ge layers produced in a similar manner emitted visible light at room temperature.

    摘要: An analyzer apparatus and method of use thereof is configured to dynamically interrogate a sample. For example, an analyzer using light interrogates a tissue sample using a temporal resolution system on a time scale of less than about one hundred nanoseconds. Optionally, near-infrared photons are introduced to a sample with a known illumination zone to detection zone distance allowing calculation of parameters related to photon pathlength in tissue and/or molar absorptivity of an individual or group through the use of the speed of light and/or one or more indices of refraction. Optionally, more accurate estimation of tissue properties are achieved through use of: knowledge of incident photon angle relative to skin, angularly resolved detector positions, anisotropy, skin temperature, environmental information, information related to contact pressure, blood glucose concentration history, and/or a skin layer thickness, such as that of the epidermis and dermis.
