Abstract:
A single fiber Mach-Zehnder interferometer comprises an optical fiber having a core region and a cladding surrounding the core region, and a micro-cavity having part of the cladding and the core region removed, wherein the micro-cavity is adapted to receive a light beam and separate the light beam into a first light beam that propagates through the micro-cavity in an unguided mode, and a second light beam that propagates through the core region in a guided mode.
Abstract:
A method for reporting location information of user is disclosed in the present invention, which is configured for achieving the report of a location information of User Equipment (UE) during the procedure that UE is handed over to another serving cell, and includes the following steps: a source evolved Node Base (eNB) initiates a handover procedure; during the handover procedure, the source eNB sends the location reporting information to a target eNB, the target eNB acquires the location information of UE based on the location reporting information and reports it to a Mobility Management Entity (MME) corresponding to the target eNB. According to the present invention, it is possible for the source eNB to notify the target eNB based on a handover request of UE that the target eNB should report the location information after the UE is handed over to another serving cell, so that the target eNB can report the location information of UE to MME during the handover procedure of the serving cells. The present invention simplifies the signalling flow and is simple to be implemented.
Abstract:
An inline microwave bandpass filter where cross coupling between non-adjacent resonators is realized by changing the orientation of selected resonators. The microwave bandpass filter includes a cavity and three or more resonators arranged in a row (or inline) in the cavity. At least one resonator has a different spatial orientation from at least one other resonator. For example, one or more of the resonators may be rotated 90 or 180 degrees with respect to one of the other resonators. This arrangement of resonators facilitates sequential coupling between pairs of adjacent resonators and cross coupling between at least one pair of non-adjacent resonators without the use of additional cross coupling structures such as dedicated coupling probes or extra cavities. One or more plates may be introduced between adjacent resonators to independently control the sequential and cross coupling.

Abstract:
Electronic devices comprising an anode, buffer layer, hole transport layer, photoactive layer, electron transport layer, electron injection layer, and cathode are provided, where the photoactive layer comprises a dual dopant in a metallic complex. The dopants are selected so that their emitting wavelengths are essentially the same, while their ionization potentials and electron affinities are substantially different. The dual dopant device allows for tuning the ionization potential of one dopant to enhance hole injection and/or minimize hole trapping, while independently tuning the electron affinity of the other dopant to enhance electron injection and/or minimize electron trapping.
Abstract:
A first wireless communications device includes a wide area network (WAN) interface and a peer to peer interface. The first device discovers the presence of a second wireless communications device via a peer discovery signal, received via its peer to peer interface. The second device has been transmitting, e.g., periodically, certain information, e.g., its location and/or shopping preferences, to a node within the WAN. The detected first signal triggers an application alert in the first device. The first device recovers past information about the second device through a second signal received via its WAN interface. The first device uses information communicated in the first signal, e.g., device identifier information, and information communicated in the second signal, e.g., past location and/or shopping information, to generate a targeted message for the second device. The first device communicates the targeted message via its peer to peer interface in a peer to peer traffic channel.
Abstract:
Transition metal complexes of selected monoanionic phosphine ligands, which also contain a selected Group 15 or 16 (IUPAC) element and which are coordinated to a Group 3 to 11 (IUPAC) transition metal or a lanthanide metal, are polymerization catalysts for the (co)polymerization of olefins such as ethylene and α-olefins, and the copolymerization of such olefins with polar group-containing olefins. These and other nickel complexes of neutral and monoanionic bidentate ligands copolymerize ethylene and polar comonomers, especially acrylates, at relatively high ethylene pressures and surprisingly high temperatures, and give good incorporation of the polar comonomers and good polymer productivity. These copolymers are often unique structures, which are described.

Abstract:
Techniques for performing automatic gain control (AGC) at a receiver are described. The receiver may receive an OFDM-based symbol composed of a cyclic prefix and a useful portion. The receiver may scale the OFDM-based symbol with an initial receiver gain, adjust the initial receiver gain based on the cyclic prefix, apply the adjusted receiver gain prior to the useful portion, and process the useful portion to recover at least one signal sent by at least one transmitter. The receiver may select the initial receiver gain, e.g., based on a predicted received power level for the at least one transmitter, a pattern of different receiver gains, etc. The receiver may apply the initial receiver gain at the start of the OFDM-based symbol. The receiver may measure the power of a set of samples in the cyclic prefix and may adjust the receiver gain based on the measured power and a target power.
