Title: Method and system for intra e-utran handover
Inventor: OLSSON LARS-BERTIL
IPC: H04W36/08
Filed: 2007-02-06
Abstract: The invention regards a handover method for a data packet based wireless mobile communications network. The network comprises a core network (CN) and a radio area network (RAN). The core network (CN) comprises a control plane node (MME) intercommunicating with a user plane node (UPE). The radio area network comprises a mobile user equipment (UE) intercommunicating with a source radio base transceiver station, eNOdeB, (source eNodeB), wherein payload data is routed via a tunnel between the user plane node (UPE) and the source eNodeB (source eNodeB), wherein the handover comprises the step of establishing a temporary tunnel between the user plane node (UPE) and a target eNodeB (target eNodeB), the handover being initiated by the target eNodeB (target eNodeB) transmitting an unreliable uplink data signal to the user plane node (UPE) comprising handover information.

Title: Lightweight audio system for automotive applications and method
Inventor: SNIDER CHRIS R
IPC: H05K9/00
Filed: 2007-08-16
Abstract: A lightweight radio/CD player for vehicular application is virtually "fastenerless" and includes a case and frontal interface formed of polymer based material that is molded to provide details to accept audio devices such as playback mechanisms (if desired) and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides EMC, RFI, BCI and ESD shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. The PCB architecture is bifurcated into a first board carrying common circuit components in a surface mount configuration suitable for high volume production, and a second board carrying application specific circuit components in a wave soldered stick mount configuration. The major components and subassemblies are self-fixturing during the final assembly process, eliminating the need for dedicated tools, fixtures and assembly equipment. The major components and subassemblies self-interconnect by integral guide and connection features effecting "slide lock" and "snap lock" self-interconnection. The radio architecture includes improved push buttons employing 4-bar living hinge linkage and front loaded decorative trim buttons.

Patent EP-2300899-A4 (EP)
Title: Systems and methods for assessing locations of multiple touch inputs
Inventor: GEAGHAN BERNARD O
IPC: G06F3/02
Filed: 2009-05-13
Abstract: Matrix-based touch input systems assess touch locations of two or more temporally overlapping touch inputs by forming valid x-y coordinate pairs from independently determined x- and y-coordinates. Valid x-y pairs are formed based on comparing one or more signal parameters such as signal magnitude, signal strength, signal width, and signal rates of change. In matrix capacitive systems where capacitance-to-ground signals are used to determine the x- and y-coordinates, the determined coordinates may be formed into valid x-y pairs using mutual capacitance measurements. When resolving more than two temporally overlapping touches, information gained by resolving a valid x-y coordinate pair of at least one of the touches may be used to resolve the remaining touches.

Title: Active leakage resistance control to improve numerical convergence in an electronic circuit simulator which seeks circuit solutions iteratively.
Inventor: WANG SANG S
IPC: G06F17/50
Filed: 1985-03-19
Abstract: Operation of an electronic circuit simulator is improved by actively controlling the test leakage resistance values at junctions (12) of active devices while seeking stable circuit solutions of modeled circuitry. By choosing an initial junction leakage resistance value lower that the actual value in each active device being modeled, convergent circuit solutions can be easily obtained, which may in turn be used as initial conditions to achieve the circuit solution for the real circuit with a significantly improved effectiveness.
Patent EP-0228369-A4 (EP)
Title: Means for pulling tape from a reel.
Inventor: HERTRICH FRIEDRICH R
IPC: G11B15/00
Filed: 1985-06-12
Abstract: The present arrangement includes a first tape leader (11) which can be readily and automatically coupled to a second tape leader (23). In a preferred embodiment the first tape leader is connected to be wound on a take up reel while the second tape leader is connected to a tape to be pulled from a supply reel. The first tape leader (11) has one end formed into a mushroom like tab (13) with a supporting stem (17). The second tape leader (23) has a locking aperture (21) at one end thereof which is proportioned so that a wide section thereof can fit over said mushroom like tab (13) while a narrow section thereof will accept the stem (17) but block passage of the mushroom tab (13) therethrough. Accordingly when the tab (13) is passed through the wide section and the leader (11) is moved (pulled) toward the narrow section of the locking aperture (21), the tab (13) and part of the stem (17) become locked in the narrow section. Hence the leaders are locked, or, buckled, to enable the first tape leader (11) to pull the second leader (23). The first and second tape leaders each have a smoothing aperture (25), (33) therein which provides a means to accept the bumps created by buckling the tab (13) into the locking aperture (21) so that the wrapped around leaders are in a smooth configuration when pulling a tape.

Title: Wet-tip die for efg crystal growth apparatus
IPC: C30B15/34
Filed: 1991-05-20
Abstract: A novel capillary die and crystal growing method are provided for growing a hollow crystalline body by EFG. Inner and outer annular moats surround the die tip. Passageways are provided for supplying melt to those moats from a crucible, so that melt in said moats will wet and cover the inner and outer exterior surfaces of the die tip during growth of a hollow crystalline body. The novel die may be constructed so as to have a lower die tip and a shorter capillary than EFG dies heretofore used to successfully grow hollow bodies. The die design facilitates keeping the temperature of the die tip substantially uniform about its circumference, thereby improving the uniformity of thickness of the wall of the crystalline body grown from a film of melt on the die tip. The moats reduce the likelihood of the growth process being interrupted or adversely affected by flooding of the die. In the event the growth meniscus breaks, liquid silicon is captured in the moats, thereby preventing or reducing the likelihood of flooding of the die and associated growth apparatus.

Abstract: Récepteur de ligne audio tolérant une plage étendue d'impédances de source équilibrées et déséquilibrées avec une détérioration minimum du rapport de réjection en mode commun du récepteur de ligne. Celui-ci comprend un amplificateur différentiel (50) comportant des amplificateurs d'entrée (52, 54) à chacune de ses entrées.
