An apparatus and method for determining a physical parameter affecting an optical sensor or a number of sensors in a network. The apparatus uses a narrow linewidth source at an emission wavelength λand an arrangement for varying the emission wavelength λof the radiation. An analysis module with curve fitting is used to generate a fit to the response signal obtained from the optical sensor. The physical parameter is determined form the fit rather than from the response signal. The apparatus can be employed with Bragg gratings, etalons, Fabry Perot elements or other optical sensors.

Tunable external cavity lasers are used in applications such as interferometry, FM spectroscopy, and optical communications equipment testing. Mode hop free high bandwidth frequency modulation operation is desired in a tunable external cavity laser. This application describes new and novel techniques for controlling the output wavelength of a tunable external cavity laser while suppressing mode hop.

A laser-emitting device may be coupled to an electro-optically controlled wavelength actuator. An electro-optically controlled wavelength actuator may be a holographic wavelength actuator or a liquid crystal wavelength actuator. The electro-optically controlled wavelength actuator may function as a tunable diffraction grating for external cavity lasers.

A system, terminal, receiver and method are provided for receiving and processing a signal received from a spread-spectrum downlink channel. The method includes receiving the signal from the downlink channel, and generating an estimate of a transmitted chip sequence in accordance with an iterative process. In this regard, the iterative process includes calculating statistical information, such as a mean and covariance, for a previous iteration of a transmitted chip sequence, the statistical information being selectively calculated based upon one of soft bits and soft symbols associated with the previous iteration of the transmitted chip sequence. The estimate for a current iteration of the chip sequence is then generated based upon the statistical information.

Devices for loading a collapsible implant onto a delivery catheter. In one aspect, a loading device comprises an outer tubular structure and an inner tubular structure. The outer tubular structure comprises a narrowing passage configured to receive a catheter at one end and a collapsible implant at another end. The inner tubular structure is configured to move slidably and co-axially within the outer tubular structure. The inner tubular structure comprises a carrier pin configured to move within the narrowing passage as the inner tubular structure slides into the outer tubular structure. The sliding of the inner tubular structure into the outer tubular structure causes an implant mounted on the carrier pin to collapse as the implant moves through the narrowing passage and into the distal end of a catheter. In an optional aspect, the outer tubular structure further comprises a grasper to stabilize the catheter for receipt of the collapsible implant, and the internal diameter of the inner tubular structure varies to cause the grasper to first contract and stabilize the catheter, and then expand and release the catheter, as the grasper moves into the inner tubular structure.

A method and apparatus in a user equipment transmit a subframe shared by multiple users through a dual-antenna transmission scheme by using space-time coding. A first and a second plurality of modulation symbols are generated. A third and a fourth plurality of modulation symbols are generated by performing Alamouti coding on each pair of modulation symbols in each of the first and second pluralities of modulation symbols. A spread matrix is generated for each modulation symbol such that the first and third pluralities of modulation symbols are mapped to a first slot of the subframe, and the second and third pluralities of modulation symbols are mapped to a second slot of the subframe. The subframe is transmitted such that the first and second pluralities of modulation symbols are transmitted via a first antenna, and the third and fourth pluralities of modulation symbols are transmitted via a second antenna.
