An apparatus and method for carrying out the affinity separation of a target substance from a liquid test medium by mixing magnetic particles having surface immobilized ligand or receptor within the test medium to promote an affinity binding reaction between the ligand and the target substance. The test medium with the magnetic particles in a suitable container is removably mounted in an apparatus that creates a magnetic field gradient in the test medium. This magnetic gradient is used to induce the magnetic particles to move, thereby effecting mixing. The mixing is achieved either by movement of a magnet relative to a stationary container or movement of the container relative to a stationary magnet. In either case, the magnetic particles experience a continuous angular position change with the magnet. Concurrently with the relative angular movement between the magnet and the magnetic particles, the magnet is also moved along the length of the container causing the magnetic field gradient to sweep the entire length of the container. After the desired time, sufficient for the affinity reaction to occur, movement of the magnetic gradient is ended, whereby the magnetic particles are immobilized on the inside wall of the container nearest to the magnetic source. The remaining test medium is removed while the magnetic particles are retained on the wall of the container. The test medium or the particles may then be subjected to further processing.

An apparatus and method to generate and restore an RTP (Real-Time Transmission Protocol) packet. A setting unit assigns a CTS (Composition TimeStamp), a DTS (Decoding TimeStamp), and a PSN (Packet Sequence Number) that sequentially increase according to a packet generation order for each of a plurality of SL (Synchronization Layer) packets, extracting a time stamp length and a packet sequence number length from an SLCD (SL Configuration Descriptor) within each SL packet. A packet generating unit generates a header of the SL packet accommodated in an RTP packet header and the RTP packet based on the CTS, the DTS, the PSN, the time stamp length and the packet sequence number length. Since only difference values in the CTS, the DTS, and the PSN information between a previous SL packet and the present SL packet, are recorded, a number of bits can be reduced if the CTS value rolls over and a multiple SL packet can be made for the SL packet having a time stamp length greater than 32 bits. Also, a condition that a DTS delta value should always be a positive number is met.

An improved wave energy converter for use in offshore and deep-sea locations. The wave energy converter is adapted for secure attachment to the bottom of a body of water (e.g., the ocean floor), preferably beyond the breaker zone. The wave energy converter is selectively adjustable in length. A hydraulic power generation system is used to convert the energy present in the waves into hydraulic power that can be use to generate electricity and for other purposes, such as desalinization. The system may include a hydraulic piston assembly, a floatation device that is connected to the piston assembly, high and low pressure hydraulic reservoirs, and a hydraulically driven power generator. The floatation device moves upward in response to rising waves, and downward under the force of gravity in response to falling waves. The system utilizes this downward gravitational force to discharge fluid from the piston assembly, which in turn, drives the power generator. A control system is used to detect water conditions and to selectively adjust the length of the support structure and the fluid flow characteristics to dynamically optimize power generation based on changing water conditions.

A multi reflection time of flight (MRTOF) mass spectrometer (12) And method for identifying a sample is disclosed. Sample ions are generated at an ion source (15). The MRTOF is a closed mirror arrangement with first and second opposed ion mirrors (20, 20′) on an axis of reflection (XX′). The MRTOF (12) also includes a bidirectional ion deflector (50) on that axis (XX′). The deflector (50) deflects ions onto the reflection axis as a short pulse at time to <zero> where they oscillate multiple times, separating in time of flight according to ion m / z. At a later time t, ions travelling in both directions along the axis (XX′) are ejected out of the MRTOF (12) by the bidirectional deflector (50) to an ion detector arrangement (55). The separation of ions in time of flight allows a “fingerprint” of a biological sample to be produced by the detector arrangement (55) without the need to assign a mass to each peak. Comparison with a library of fingerprints permits identification.

An improved elliptical path exercise machine is provided that is simple and robust in its construction, requires minimal maintenance, provides smooth even exercise motion, and which has a compact foot-print. The apparatus includes a pair of planetary gears, sun / ring gears and at least one crank. The crank is supported and arranged so as to be rotatable about a crank axis. Each planetary gear is pivotably secured to the crank about a pivot point located and arranged such that as the crank is rotated the planetary gears engage and rotate relative to their corresponding sun / ring gears while simultaneously revolving about the crank axis so as to form right and left epicylic gear trains. Two foot pedals are each pivotably secured to a corresponding one of the planetary gears and are sized and arranged to support the feet of a user. The layout and geometries of the device are such that each foot-pedal follows a substantially elliptical foot-path as the crank is rotated. The major axis of the elliptical foot-path is greater than twice the effective crank-arm length of the crank so that a compact foot print is attained.

Electrode and nozzle that seat within a retaining member and in two different seating locations relative to retaining member. The electrode and nozzle each include an interwoven-double-start thread having two thread cuts, which start 180 degrees from one another as measured around the circumference of the electrode or nozzle. Additionally, the retaining member includes an interwoven-double-start thread having two thread cuts, which start 180 degrees from one another as measured around the circumference of the electrode or nozzle. Because of the configuration of the interwoven-double-start threads, the two seating locations of the electrode and nozzle are 180 degrees apart thereby enabling the electrode and nozzle to be used twice as long as conventional electrodes and nozzles which include a single cut thread. Further, the electrode, nozzle, and retaining member include mating frustum surfaces, which are configured and dimensioned so that the electrode and nozzle seat within the retaining member with less than one turn of the electrode and nozzle relative to the retaining member. Therefore, the electrode and nozzle may be quickly inserted in, and removed from, the retaining member. Moreover, the mating frustum surfaces, and interwoven-double-start threads provide a large area of contact between the electrode and nozzle and retaining member hence providing a strong connection, as well as reducing resistance heating, therebetween.

The disclosure provides a semi-submersible offshore platform with columns having an enlarged base on the bottom of each column with pontoons coupled between the columns. The enlarged column base can be at least as high as a height of the pontoon and on at least embodiment can be about 50% of the draft of the platform. The enlarged base can change a current flow shape around the base and columns for lower VIM. An outside corner of the base can be trimmed at an angle. Alternatively, the lower portions of the columns can be extended horizontally outward to form an effectively enlarged base having similar characteristics. In some embodiments, the pontoon volume can be reduced inversely proportional to the base enlargement to have comparable total buoyancy.
