Dual-lensed unitary optical receiver assembly
InactiveUS7556440B2Efficient couplingReducing cost and complexityCoupling light guidesElectromagnetic receiversAspheric lensPhysics
A unitary optical receiver assembly is formed to include a V-groove passively aligned with a first aspheric lens (the lens formed along a surface perpendicular to the V-groove). An optical fiber is disposed along the V-groove and is used to bring the received optical signal into the unitary assembly. Upon passing through the first aspheric lens, the received optical signal will intercept a 45° turning mirror wall that directs the signal downward, through a second aspheric lens (also molded in the unitary assembly), and then into a photosensitive device. Advantageously, the photosensitive device is disposed in passive alignment with the second aspheric lens, allowing for a received signal to be coupled from an incoming optical fiber to a photosensitive device without needing any type of active alignment therebetween.

Intraoperative dynamic trialing
ActiveUS20150057758A1Reducing cost and complexityFacilitate intraoperative trialingJoint implantsComputer-aided planning/modellingKinematicsFemoral condyles
A dynamic trialing method generally allows a surgeon to perform a preliminary bone resection on the distal femur according to a curved or planar resection profile. With the curved resection profile, the distal-posterior femoral condyles may act as a femoral trial component after the preliminary bone resection. This may eliminate the need for a separate femoral trial component, reducing the cost and complexity of surgery. With the planar resection profile, shims or skid-like inserts that correlate to the distal-posterior condyles of the final insert may be attached to the distal femur after the preliminary bone resection to facilitate intraoperative trialing. The method and related components may also provide the ability of a surgeon to perform iterative intraoperative kinematic analysis and gap balancing, providing the surgeon the ability to perform necessary ligament and / or other soft tissue releases and fine tune the final implant positions based on data acquired during the surgery.

Metal-enhanced fluorescence for the label-free detection of interacting biomolecules
InactiveUS20100035335A1Enhance intrinsic fluorescenceReducing cost and complexityBioreactor/fermenter combinationsBiological substance pretreatmentsNanostructured metalElectromagnetic radiation
A method for enhancing fluorescence of a biomolecule includes the step of associating the biomolecule having intrinsic fluorescence with a sensing surface that contains nanostructured metal. Association of the biomolecule with the nanostructured metal enhances its intrinsic fluorescence, which is detected upon exposure to electromagnetic radiation of a suitable wavelength. The sensing surface may include capture or ligand molecule which binds to the biomolecule and sequesters it in proximity to the nanostructured metal, thereby causing its fluorescent signal to be enhanced. The method can be used in label-free bioassays for detection of interacting biomolecules, such as antibody-antigen binding.

Door latch with emergency lock actuator and 'impatient passenger' feature
ActiveUS20110204673A1Low costReduce complexityPower transmission/actuator featuresElectrical locking circuitsDrive motorEngineering
In one aspect, the invention is directed to a closure latch for a vehicle door. The closure latch includes an emergency lock actuator to permit a person to lock the door in the event that the power lock actuator is unusable. The latch also includes an ‘impatient passenger’ feature, which permits the doors to be unlocked using the remote keyless-entry feature on the key fob even in a situation where an ‘impatient passenger’ had prematurely lifted the door handle of the vehicle. In some prior art latches, such an action by an ‘impatient passenger’ would prevent the drive motor on the latch from unlocking the latch, thereby necessitating the owner to press the unlock button on the key fob a second time. There is some overlap in the components that used for the ‘impatient passenger’ feature and the components used for the emergency lock actuator, thereby reducing cost and complexity of the latch.

Trust management systems and methods
ActiveUS7313692B2Reducing cost and complexityEfficient managementDigital data processing detailsComputer security arrangementsDecision takingAuthorization
The present invention provides systems and methods for making efficient trust management decisions. A trust management engine is provided that processes requests for system resources, authorizations or certificates, and the identity of one or more root authorities that are ultimately responsible for granting or denying the requests. To determine whether a request should be granted, the trust management engine identifies a set principals from whom authorization may flow, and interprets each of the certificates as a function of the state of one or more of the principals. The processing logic iteratively evaluates the functions represented by the certificates, updates the states of the principals, and repeats this process until a reliable determination can be made as to whether the request should be granted or denied. The certificates may be evaluated until the state of the root authority indicates that the request should be granted, or until further evaluation of the certificates is ineffective in changing the state of the principals.

A method and apparatus for processing substrate edges is disclosed that overcomes the limitations of conventional edge processing methods and systems used in semiconductor manufacturing. The edge processing method and apparatus of this invention includes a laser and fiber-optic system to direct laser radiation onto a rotating substrate supported by a chuck.

On-the-fly redundancy operation for forming redundant drive data and reconstructing missing data as data transferred between buffer memory and disk drives during write and read operation respectively
InactiveUSRE39421E1Improve disk array performanceImproved disk array performanceInput/output to record carriersStatic storageMultiplexingData stream
A disk drive array controller and method carries out disk drive data transfers not only concurrently but also synchronously with respect to all of the drives in the array. For synchronous operation, only a single-channel DMA is required to manage the buffer memory. A single, common strobe is coupled to all of the drives for synchronous read and write operations, thereby reducing controller complexity and pin count. A ring-structure drive data bus together with double buffering techniques allows use of a single, common shift clock instead of a series of staggered strobes as required in prior art for multiplexing / demultiplexing buffer memory data, again providing for reduced controller complexity and pin count in a preferred integrated circuit embodiment of the new disk array controller. Methods and circuitry also are disclosed for generating and storing redundant data (e.g. “check” or parity data) “on the fly” during a write operation to a RAID array. Techniques also are disclosed for reconstructing and inserting missing data into a read data stream “on the fly” so that a disk drive failure is transparent to the host.
