In a duplex radio link wherein digital data information from a data interface is transmitted from a local terminal to a remote terminal over fading dispersive channels, a method and transceiver are described that provide for transmission at an adaptive data rate. The transmission is at a constant symbol rate so that the signal bandwidth can be fixed and at the remote terminal receiver the input sampling rate can be fixed. The digital data information is transmitted over a constant data rate interval in accordance with a selected data rate mode that is a function of direct sequence spreading gain, error correction code rate, and signal constellation type. The data rate is adapted by selecting a data rate mode that is a function of the arrival rate of data packets from the data interface and a link quality measure fed back from the remote terminal. The data packet arrival rate is controlled as a function of the link quality measure and the current data packet arrival rate. In systems with multiple transmit diversity channels, independent data is sent over each of the transmit diversity channels. The adaptive data rate technique utilizes both orthogonal transmit diversities such as frequency and troposcatter polarization diversity as well as nonorthogonal transmit diversities in a Multiple-input Multiple-Output (MIMO) configuration. A single antenna troposcatter link using angle diversity and adaptation of data rate by feedback communications is described. In an idealized feedback communication example, the single antenna system in a Ku-band application is shown to have 15.5 times the data rate capability of a conventional two-antenna system at S-band.

A magnetic sensing element detects the presence of magnetic particles in a binding assay. The magnetic sensing element has at least one planar layer of electrically conductive ferromagnetic material that has an initial state in which the material has a circular magnetic moment within the plane of the layer. The magnetic sensing element has molecules of a first specific binding member attached to it. The device also includes a fluid test medium to which the magnetic sensing element is exposed during the course of a binding assay. The fluid test medium includes magnetizable particles that become immobilized during the assay in relation to the amount of analyte in the test medium. The relative size of the magnetic particle and the magnetic sensing element and the location of the molecules of the first specific binding member on the magnetic sensing element are selected so that when the magnetic particle becomes immobilized with respect to the magnetic sensing element, the radial fringing field of the magnetic particle causes the magnetic moment of at least one layer of electrically conductive ferromagnetic material to shift from circular to radial, thereby causing a detectable change in the electrical resistance of the magnetic sensing element.

A downhole drilling apparatus incorporating an orientation sensor (24) is disclosed. The orientation sensor is mounted to a housing (16) for providing a signal representing the orientation of the housing, and is connected to a first transceiver coil (26). A second transceiver coil (30) and a series of magnets (32) are mounted to a rotary shaft (18). As the shaft rotates relative to the housing, passage of the magnets past the first transceiver coil generates a voltage to provide electrical power to the sensor, and electromagnetic coupling between the first and second transceiver coils enables signals from the sensor to be transmitted to a measurement while drilling tool mounted on the rotary shaft.

The invention relates to structures useful for the manufacture of electronic components, which comprise a substrate, a strain holding layer, and a layer of a strained semiconducting material. These structures are particularly useful where islands are later formed in the strained semiconducting material because the strain holding layer limits relaxation of stress in the islands. This invention also relates to processes for making a these structures.

Coprocessed compositions containing microcrystalline cellulose and calcium carbonate, wherein the weight ratio of microcrystalline cellulose to calcium carbonate is relatively high, are useful as excipients in the preparation of solid dosage forms containing active pharmaceutical ingredients, particularly those prepared by processes involving multiple compaction steps. Such compositions may be obtained, for example, by preparing aqueous slurries or wet masses of microcrystalline cellulose and calcium carbonate and drying such slurries or wet masses to produce particulate products. The coprocessed products exhibit improved recompactibility, as compared to coprocessed products having lower microcrystalline cellulose:calcium carbonate weight ratios or as compared to physical dry blends of the two excipients.
