Scanning probe microscope
A portion of light emitted from a laser source (11) for detecting a displacement of a cantilever (4) is extracted by a half mirror (20) and guided onto a photodetector (21) having a light-receiving surface divided into four sections. When the direction of the emitted light is inclined due to a change in the ambient temperature or other factors, the light spot formed on the light-receiving surface of the photodetector (21) moves. Accordingly, the amount and direction of the inclination of the emission direction can be recognized from the amount and direction of the movement of the light spot. A drive amount calculator (22) calculates a drive amount according to the amount and direction of the inclination, and operates an actuator (23) to rotate the laser source (11) around each of the Y and Z axes. This operation compensates for the inclination of the direction of the emitted light and thereby prevents the inclination from being falsely recognized as an irregularity on the sample surface.

A high power laser source comprises a bar of laser diodes having a first coefficient of thermal expansion CTEbar on a submount having a second coefficient CTEsub and a cooler having a third coefficient CTEcool. The submount/cooler assembly shows an effective fourth coefficient CTEeff differing from CTEbar. This difference leads to a deformation of the crystal lattice of the lasers' active regions by mechanical stress. CTEeff is selected to be either lower than both CTEbar and CTEcool or is selected to be between CTEbar and CTEcool. The submount may either comprise layers of materials having different CTEs, e.g., a Cu layer of 10-40 μm thickness and a Mo layer of 100-400 μm thickness, or a single material with a varying CTEsub. Both result in a CTEsub varying across the submount's thickness.
Eye-safe Q-switched short pulse fiber laser
A laser includes a pump source that provides pump energy at a first wavelength and a laser cavity. The laser cavity includes a laser gain medium that receives the pump energy from the pump source and creates gain at a second wavelength different from the first wavelength, and a mode stripping portion coupled to the laser gain medium. The mode stripping portion causes the laser cavity to have a low Fresnel number so as to allow only the lowest-order fiber mode to resonate in the laser cavity. Higher-order fiber modes are discriminated against so as to generate a laser output having a substantially diffraction limited beam in a single transverse mode at the second wavelength.

Methods and apparatus for improved communications networks
Erroneous data due to faults are prevented from propagating through a distributed network node having diversely routed communications links by using a fault masking technique that eliminates the 60 ms of error propagation time associated with SONET networks. The fault masking technique can also prevent random bit errors from propagating through the distributed network node. A frame alignment technique used in the network node is scalable for very wide words (e.g., 128 bits) for use with high speed optical communications protocols, such as OC-192.
Multi-channel code-division multiplexing in front-end integrated circuits
A challenging problem is maintaining low power consumption in multi-channel (MC) systems, where multiple input signals demand several front-end analog signal-processing blocks to be replicated. A code-division multiplexing (CDM) system can be generalized as a signal compression-decompression involving an analog-to-digital converter (ADC). This invention utilizes CDM in MC front-end integrated circuits to significantly reduce the power consumption of such systems. The invention also extends CDM's data compression advantages to uncorrelated and weakly correlated MC signals through the introduction of a new Multi-Channel Signal Binning and Multiplexing (MCSBM) method and architecture. The proposed method achieves significant reductions in power consumption in comparison to a conventional time-division multiplexing quantizer, while adding only a modest amount of overhead and complexity. Among other advantages, the invention permits architects to fabricate MC integrated circuits with ultra low power consumption and small chip area, where conventional architectures could not. Another embodiment of the invention relates to the system's compressor organizing samples of the input signal in such a way that the downstream ADC quantizes the higher variance samples with a higher resolution compared to the resolution it uses to quantize other samples with lower variance.

The assigned resources may include multiple tiles, with each tile corresponding to a block of time frequency resources. The subpackets may be mapped to the tiles such that (i) the subpackets are mapped to equal number of tiles to achieve similar decoding performance, (ii) each subpacket is mapped to at least NMIN tiles, if available, to achieve a certain minimum diversity order for the subpacket, and/or (iii) each subpacket is mapped to a subset of the multiple tiles, if possible, so that the subpacket can be decoded without having to demodulate all of the tiles.
Method and system for adaptively obtaining bandwidth allocation requests
A method and apparatus for adaptively obtaining bandwidth requests in a broadband wireless communication system. The method and apparatus includes dynamically varying technique combinations enabling a plurality of users to efficiently request bandwidth from a shared base station. A user may “piggyback” a new bandwidth request upon, or set a “poll-me bit” within, presently allocated bandwidth. A base station may poll users, individually or in groups, by allocating unrequested bandwidth for new requests. Polling may respond to a “poll-me bit,” and/or it may be adaptively periodic at a rate based on communication status parameters, such as recent communication activity and connection QoS levels. Group polling permits a possibility of collisions. Polling policies may be established for dynamically varying user groups, or may be determined for each user. Dynamic selection of appropriate polling techniques makes use of efficiency benefits associated with each technique.

When acoustic signal packets are communicated over an IP communication network, data corresponding to an acoustic signal (acoustic signal corresponding data) has been included and transmitted in a packet different from a packet containing the acoustic signal. However, conventionally, a packet in which the acoustic signal corresponding data is to be included must be determined beforehand and cannot dynamically be changed.According to the present invention, the amount of delay of acoustic signal corresponding data with respect to an acoustic signal is contained in an acoustic signal packet as delay amount control information. Furthermore, the conditions of a communication network are detected from the number of packets lost in a burst loss or jitters and the number of the packets to be stored and the amount of delay at the receiving end are thereby determined.

Application-aware policy enforcement
An application-aware policy enforcement point (PEP) attaches to the edge of a packet-switched network to manage loading when the network nears or exceeds its capacity due to changes in the network, e.g., component failures or incremental growth. An advanced bandwidth manager (ABM) comprises a session/call admission controller (S/CAC) that monitors and maps ever-changing network topology information gathered from remote listeners about how traffic is being routed through various parts of the network. These reports are harmonized to build a single view of the network topology, and the point-to-point connections are abstracted into path tables. Autonomous PEP's at the network's edges provide short-term, application-aware controls on their own that are applied to the corresponding network ingress traffic. The S/CAC uses the path tables to calculate whether particular PEP's can admit more traffic, or should they shed sessions/calls to keep service up for the existing application traffic. Long-term controls are periodically downloaded as admission tables from the S/CAC to the PEP's.
