摘要:
The mode transforming structure includes a first waveguide structure. A slot waveguide region is coupled to the first waveguide structure. The slot waveguide region includes one or more complementary tapered pairs so near lossless transforming between the first waveguide structure and the slot waveguide region occurs so as to allow optical modes to be transferred between the first waveguide and the slot waveguide region.

A tunable laser includes an optical cavity comprising a first and second mirror. A gain medium is positioned in the optical cavity that generates stimulated emission in the optical cavity when biased. A thermally tunable optical filter is positioned in the optical cavity that is heated to a temperature that selects a desired optical mode of the optical cavity. A thermally tunable optical phase retarder is positioned in the optical cavity that is heated to a temperature which changes an optical path length in the optical cavity by an amount corresponding to a resonant frequency of the tunable optical filter so that a phase-matching condition of the optical cavity is shifted to the desired optical mode of the optical cavity selected by the thermally tunable optical filter.

This invention describes a method, apparatus and system for a mobile-station cell system, MSCell for short. An MSCell operates in a wireless network, more specifically in a cell of the wireless network. It interacts with the cell's BS the way a regular MS(s) do. The MSCell consists of an MSCell base and multiple MSCell terminals. The MSCell base simulates the regular MS(s) to set up one or more radio connections with the BS and simultaneously serves its own MSCell terminals. In other words, the MSCell behaves simultaneously as regular MS(s) to the BS and as the base to all its MSCell terminals. The MSCell terminals gain services from the wireless network through the MSCell base. The MSCell can also operate independently of any BS to be a self-contained standalone system where its MSCell terminals can call each other.

A clean room shoe article, e.g., shoe, boot, safety shoe, safety boot. The article has a sole region. The article has an upper particle free polymer material having a toe region and an ankle region. The upper particle free polymer material is coupled to the sole region. The upper particle free polymer material is capable of enclosing a foot of a human user. The toe region houses an entirety of toes of the human user. The article has a steel toe housing member enclosing and protecting the entirety of the toes of the human user. The article has an enclosure provided in the toe region of the upper particle free polymer material. The enclosure is adapted to house the steel toe housing member. A sealing region is provided within a vicinity of the enclosure. The sealing region is adapted to maintain the steel toe housing member within the enclosure and is also adapted to open and remove the steel toe housing member from the enclosure provided in the toe region of the upper particle free polymer member.
摘要:
Four unique transcripts have been isolated from the &bgr; chain of the T cell receptor in T cells in the synovial tissue of a patient with rheumatoid arthritis. Two of these transcripts were isolated from fresh synovial tissue and two were isolated from a T cell line derived from the synovial tissue. The sequences of the four transcripts are highly homologous, with a conserved amino acid sequence of IGQ_N in the highly diverse V-D junction. The &agr; chain and the antigenic specificity of the T cell line derived transcripts has also been characterized.

A thermally tunable Fabry-Perot optical filter includes a single crystalline sheet resistance heater layer. A single crystalline semiconductor spacer layer is positioned proximate to and in thermal communication with the single crystalline sheet resistance heater layer. A first distributed Bragg reflector is positioned proximate to a first surface of the single crystalline semiconductor spacer layer. A second distributed Bragg reflector is positioned proximate to a second surface of the single crystalline semiconductor spacer layer.

Four unique transcripts have been isolated from the .beta. chain of the T cell receptor in T cells in the synovial tissue of a patient with rheumatoid arthritis. Two of these transcripts were isolated from fresh synovial tissue and two were isolated from a T cell line derived from the synovial tissue. The sequences of the four transcripts are highly homologous, with a conserved amino acid sequence of IGQ.sub.-- N in the highly diverse V-D junction. The .alpha. chain and the antigenic specificity of the T cell line derived transcripts has also been characterized.
