摘要:
The development of miniaturized chromatographic systems localized within individual polymer microspheres and their incorporation into a bead-based cross-reactive sensor array platform is described herein. The integrated chromatographic and detection concept is based on the creation of distinct functional layers within the microspheres. In this first example of the new methodology, complexing ligands have been selectively immobilized to create 'separation' layers harboring an affinity for various analytes. Information concerning the identities and concentrations of analytes may be drawn from the temporal properties of the beads' optical responses. Varying the nature of the ligand in the separation shell yields a collection of cross-reactive sensing elements well suited for use in array-based micro-total-analysis systems.

There is disclosed a continuously variable ratio transmission unit having first and second discs mounted for rotation about a main axis, a toroidal cavity being defined between the discs by facing surfaces thereof and containing a plurality of rollers which serve to transmit drive from one disc to the other, each roller being coupled to a respective carriage through a respective bearing arrangement and each carriage being coupled at a first extremity to a first linear actuator and at a second extremity to a second linear actuator whereby the carriage is movable along a direction transverse to the main axis, the first and second linear actuators working in opposition to exert an adjustable net force on the carriage, the orientation of the carriage being constrained and the bearing arrangement being such as to enable the roller to rotate about a roller axis to thereby transmit drive from one of the discs to the other and also being such as to enable the roller axis to precess relative to the carriage to vary the transmission ratio.

The present invention aims to provide a system that allows multiple users operating a PDA (Personal Digital Assistant) to access the Internet or the World Wide Web (WWW), and to be able to view and interact with these images remotely on a display screen. The invention provides a client and server system to facilitate multiple PDA users simultaneously on a single server, which has multiple virtual machines contained within, with each virtual machine containing a web browser. The invention relates to the priority in which packets or blocks of information are transferred to and displayed on the screen of the PDA device. The invention also relates to the interlacing of blocks and the construction of such blocks displayed on the PDA screen. The invention further relates to the sending, receiving, and acknowledgement of these blocks between the PDA and server.

A gripper for a test or isolation plug is provided. The gripper includes at least one gripper segment having a pipe or tube confronting surface with a plurality of separate rows of gripper teeth longitudinally-spaced apart on the surface. Each of the separate rows of gripper teeth comprising an alternating array of individual tips and gaps such that each row is serrated along its length.

The invention features a series of bags having perforations on the front and back panels that connect the back portion of one bag with the front portion of a second bag. The bags are aligned and features holes that are adapted to be received by a stand to support the bags. The bags are packaged and ready to load in a ready to use position. When the bags are separated from each other, the next bag m the continuous series will align and expand to open into a use position. The bags can be stacked on top of each other in a ready to use position.

A method, apparatus, and system in which an integrated circuit comprises an initiator Intellectual Property (IP) core, a target IP core, an interconnect, and a tag and thread logic. The target IP core may include a memory coupled to the initiator IP core. Additionally, the interconnect can allow the integrated circuit to communicate transactions between one or more initiator Intellectual Property (IP) cores and one or more target IP cores coupled to the interconnect. A tag and thread logic can be configured to concurrently perform per-thread and per-tag memory access scheduling within a thread and across multiple threads such that the tag and thread logic manages tags and threads to allow for per-tag and per-thread scheduling of memory accesses requests from the initiator IP core out of order from an initial issue order of the memory accesses requests from the initiator IP core.

In general, this disclosure describes techniques for unlocking certain functionality of a mobile computing device upon wirelessly detecting that an external device is in relatively close proximity to the mobile computing device. One example method comprises: providing a phone application and a second, different application; initiating a first mode of operation when the mobile computing device becomes locked; prohibiting user access to the second application during the first mode of operation when the mobile computing device fails to wirelessly detect a presence of an external device; and initiating a second mode of operation when the mobile computing device wirelessly detects the presence of the external device and when the mobile computing device has received user input specifying an access password, wherein the mobile computing device allows complete user access to both the phone application and the second application during the second mode of operation.
