Microfabricated crossflow devices and methods
InactiveUS7294503B2Increase sensitivityHigh numberSludge treatmentFixed microstructural devicesMain channelEnzyme
A microfluidic device for analyzing and / or sorting biological materials (e.g., molecules such as polynucleotides and polypeptides, including proteins and enzymes; viruses and cells) and methods for its use are provided. The device and methods of the invention are useful for sorting particles, e.g. virions. The invention is also useful for high throughput screening, e.g. combinatorial screening. The microfluidic device comprises a main channel and an inlet region in communication with the main channel at a droplet extrusion region. Droplets of solution containing the biological material are deposited into the main channel through the droplet extrusion region. A fluid different from and incompatible with the solution containing the biological material flows through the main channel so that the droplets containing the biological material do not diffuse or mix. Biological material within the droplets can be analyzed and / or sorted by detecting a predetermined characteristic of the biological sample in each droplet and sorting the droplet accordingly.

Ocular analyte sensor
InactiveUS6681127B2Increase rangeIncrease sensitivityNanotechMedical devicesInterstitial fluidIntracellular Fluid
An ophthalmic lens comprising a receptor moiety can be used to determine the amount of an analyte in an ocular fluid. The receptor moiety can bind either a specific analyte or a detectably labeled competitor moiety. The amount of detectably labeled competitor moiety which is displaced from the receptor moiety by the analyte is measured and provides a means of determining analyte concentration in an ocular fluid, such as tears, aqueous humor, or interstitial fluid. The concentration of the analyte in the ocular fluid, in turn, indicates the concentration of the analyte in a fluid or tissue sample of the body, such as blood or intracellular fluid.

Communications within population of wireless transceivers based on common designation
InactiveUS20060018274A1Increase sensitivityIncrease rangeEnergy efficient ICTPosition fixationReceiptPopulation
A method of forming an ad hoc hierarchical communication network among a plurality of wireless transceiver includes assigning to each of the transceivers one or more common designations. A network organization routine of the transceivers operates to establish hierarchical networks based on the transceivers' common designations, resulting in a logical network organization that provides efficiencies for acquiring information from particular transceivers that share a common designation. Each transceiver's common designation is used by a digital processor of the transceiver to selectively receive data packets that are intended for receipt by transceivers sharing the particular common designation. Such a “common designation” network reduces power consumption and signal interference, which increases battery life in the transceivers. The transceivers may include a query handling routine in communication with a memory of the transceiver for serving as a dynamic distributed hierarchical database system of information such as, for example, sensor-derived information and time-sensitive information.

In a positron emission tomography (PET) scanner, the detectors are configured to detect a greater number of lateral LORs than the number of anterior / posterior LORs passing through a patient. The increased sensitivity to the lateral LORs compensates for the increased distance that the lateral LORs travel through the patient than the anterior / posterior LORs. In one embodiment, at least one pair of partial rings are positioned adjacent fixed detector rings. In another embodiment, panel detectors with a longer length than the other detectors are positioned to be responsive to the lateral LORs. In still another embodiment, detectors rotated with a variable angular speed, spending more time measuring lateral LORs than measuring anterior / posterior LORs.

A low-water cut-off system [A] determines if fluid [W] within a boiler or other enclosure drops below a predetermined level within the enclosure. A signal generator introduces a signal into the enclosure so that the signal is present for sensing at the predetermined level, where a probe is provided for sensing the signal if present as occurs if the water is at the predetermined level. A control, which includes a microcontroller, is responsive to the probe for providing a control function in response to whether the signal is so sensed by the probe, and so to determine if water has dropped below the predetermined level. The function may be causing alarm signalling or boiler heating cut-off. Self-test and time delay features are also included. Provision is made so that the control compensates for variation in electrical conductivity of the water through which the probe signal is sent, including circuitry to adjust for a wide range of possible purity levels.
