Inventor: FUKAYA YOSUKE
IPC: H01M8/02
Filed: 2008-03-04
Abstract: A positioning mark (20) has a shape by which a position and a direction can be identified when moved together with a separator (10) along a plane. In other words, the positioning mark (20) is formed, for example, in a cross shape so that a position on the X-axis and a position on the Y-axis and the tilt in the ? direction of the positioning mark (20) can be identified. The positioning mark (20) is optically read by, for example, a sensor, and the positions on the x-axis and the Y-axis of the positioning mark (20) are calculated by, for example, image analysis processing. Based on the calculation result, positioning of the separator (10) is performed.

Inventor: MARTENS ARD
IPC: F04D29/70
Filed: 2009-12-01
Abstract: A method for removing deposits from at least one compressor powered by an engine. The method comprises disconnecting, while the engine is turned off, a high pressure downstream side of the compressor from an intercooler, or an air intake manifold for non-intercooled engines, while leaving the compressor attached to a means used in the engine to drive the compressor.

Abstract: The present invention relates to a system and a method for handling multimedia conference calls in a telecommunication network. In order for a first terminal (111) in a group (110) to determine the capabilities of at least on other terminal (112-114) in the group (110), a query message can be sent to the other terminal (112-114). When using SIP (Session Initiation Protocol), the query is performed by the method of sending an OPTIONS message. A limitation with this method is that each terminal (111) in the group needs to send a query to all the other terminals (112-114) in the group in order to determine the capabilities of each other. The invention comprises a common server (100) which is adapted to collect information about the capabilities for the terminals (112-114) in the group and to determine a common set of capabilities which is sent to the first terminal (111).

Abstract: Systems and methodologies are described that facilitate scrambling of dow nlink reference signals utilizing a pseudo-random sequence (PRS) correspondi ng to a primary synchronization code (PSC) and secondary synchronization cod e (SSC) combination. Utilization of the combination allows for orthogonal se quencing to be removed from the scrambling. This can be beneficial, for exam ple, where resources required for orthogonalizing the reference signal outwe igh the benefit of utilizing the orthogonal sequences. In such scenarios, se lective scrambling can be utilized such that the orthogonal sequence or inst ead the PSC/SSC combination can be provided to leverage advantages of both m echanisms in the given scenarios.

Abstract: A reduction in speckle patterns in the reconstruction of a 3D scene can be achieved by way of averaging. In a holographic reconstruction device, speckle patterns are intended to be suppressed while taking account of the visible resolution of the reconstruction of the scene. The holographic reconstruction device is designed such that the visible resolution of the reconstruction of the scene is matched to the resolution capability of the human eye, to the imaging properties of the reconstruction means (RM) used or to the resolution capability of the light modulation means (SLM) used.  Method steps are carried out, in which a grid scale for the object points (OP) is generated by way of system control means (SM) in each case in a plane of intersection (SE), which grid scale cannot be used to separately resolve adjacent object points (OP) in the plane of intersection (SE), and the compilation of object points (OP) of the respective plane of intersection (SE) to form an object point group with adjacent object points (OP) which can be separately resolved is carried out. In holographic displays, the invention is used to reduce speckle patterns and reduce the number of the holograms of object points of the scene, which are to be calculated and coded, and the calculation complexity.
