An optical coupler for parallel coupling from a single mode optical fiber, or fiber ribbon, into a silicon-on-insulator (SOI) waveguide for integration with silicon optoelectronic circuits. The optical coupler incorporates the advantages of the vertically tapered waveguides and prism couplers, yet offers the flexibility of planar integration. The optical coupler may be fabricated using wafer polishing technology or grayscale photolithography. The optical coupler can be packaged using epoxy bonding to form a fiber-waveguide parallel coupler or connector.

In primary press forming process, a piece of blank sheet metal is draw worked so as to form a preformed work piece (Wb) provided with a bent portion (a) substantially conforming to a three dimensional contour of a leading edge of a blade to be protected and extending along a longitudinal direction, and a pair of planar portions (b and c) extending from either side of the bent portion. In a secondary press forming process, the planar portions (b and c) of the preformed work piece are stretch formed into a final shape that conforms to the corresponding profile of the blade while the bent portion (a) of the preformed work piece is clamped and protected from deformation. In other words, the bent portion of an edge protector (100) is already given with the final shape of the edge protector by the primary press forming process while the planar portions (b and c) thereof are given with the final shape by the secondary press forming process so that the two press forming processes can be executed without interfering with each other, and only two relatively simple press forming processes are required for forming the complex three dimensional shape of the edge protector.

An enclosure is provided generally in the form of a box which provides a controlled thermal environment for the occupant. The enclosure includes a horizontal base supporting four corner posts extending vertically up from the base, with a roof above the posts and parallel with the base. A rear wall extends in a vertical plane from the base up to the roof. A pair of side walls extend from the base up to the roof. The side walls preferably include surfaces to maximize maintenance of heat within the enclosure particularly near a position for an occupant's head. Thermal sources (i.e. incandescent light bulbs) are located within the enclosure to increase an amount of infrared radiation for heating within the enclosure. A width tuning system is provided to precisely position a distance of the side walls away from each other so that thermodynamic resonance between the side walls can be maximized.

Techniques for efficiently and economically providing data transfer through wireless data networks. These techniques are particularly suitable for Internet data transfers. In one aspect, mobile devices are able to be allocated additional wireless channels to obtain increased data transfer capabilities. The additional wireless channels can be used for unicast, multicast or broadcast of data. These techniques provide additional wireless bandwidth to mobile devices and allows control over allocation of the additional wireless bandwidth.

A method and system for robust delimiting of messages in switched-carrier operation in which a preamble precedes each message. The preamble comprises symbols transmitted at a rate lower than that of the following data. The lower rate significantly increases the probability that decoding of the preamble symbols will be error-free. Communication line control information can be included in the preamble, thereby ensuring that line control information is reliably transferred over the channel. The preamble's first symbol can be transmitted at the lower symbol rate and at an increased power level, thereby reliably delimiting the beginning of a transmission. The end of the message can be reliably delimited by sending the first symbol which contains only bits from a next cell of information at a lower symbol rate, and including an extra bit in that symbol. The extra bfit can indicate to a receiver when the last cell of information begins.
