Patent number: 7927048Abstract: The invention relates to a device (20) comprising a workpiece spindle (21) for receiving a gear wheel (25), a tool spindle (29) for receiving a tool and several drives (X, Y, Z, B, C, A1) for machining the gear wheel in individual divisions. According to the invention, one tooth gap of the gear wheel is machined and then the tool is displaced in relation to the gear wheel in order to remove the tool from the tooth gap. The gear wheel is then rotated by a division and the tool is placed against the wheel again to machine another tooth gap. One of the drives (C) can be controlled in such a way that the relative displacement involves a tilting displacement, which modifies the relative angle between the tool and the gear wheel, the tilting displacement being co-ordinated with the displacement of a division.Type: GrantFiled: September 25, 2004Date of Patent: April 19, 2011Assignee: Klingelnberg GmbHInventors: Jürgen Gumpl, Roland Dutschk, Roger Kirsch

Patent number: 7922187Abstract: Gentle and substantially linear vertical motion of a wheelchair foot support is expected to provide superior results for maintenance of a wheelchair user's leg muscle mass' thus reducing atrophy of the wheelchair user's legs. Additionally, gentle continuous motion of the foot support is expected to aid in maintaining elasticity of the wheelchair user's leg joint ligaments' thus reducing contractures. Accordingly, an atrophy-reducing wheelchair includes a movable foot support mounted to a linkage that is movably connected to the wheelchair frame. As the wheelchair moves in normal operation, rotation of a wheelchair wheel drives the linkage to provide substantially linear vertical reciprocation of the foot support.Type: GrantFiled: October 15, 2008Date of Patent: April 12, 2011Inventor: Bonnie Fremgen

Patent number: 7921224Abstract: In a method for controlling data traffic in a wireless or other communication network, one or more hardware/software agents are deployed to interface with one or more network entities such as routers, switches, backhaul transmission lines, and wireless base stations. The agents monitor the L1 (physical) and L2 (data link) layers of the network for the presence of indicators associated with network failover operations, such as DS1 alarms and protocol errors, respectively. Based on detected indicators across all monitored network entities, the agents determine if a failover operation has occurred. If so, data congestion associated with the failover operation is controlled according to a failover congestion monitoring and recovery mode (e.g., a data source backoff model), to reduce instances of dropped calls that would otherwise occur if the failover congestion were handled according to a general purpose congestion monitoring and recovery mode of the network.Type: GrantFiled: December 29, 2006Date of Patent: April 5, 2011Assignee: Alcatel-Lucent USA Inc.Inventors: Sandesh R. Jajoo, Chandrashekar Sodankoor

Patent number: 7912622Abstract: A fuel injection amount learning and controlling method capable of learning the amount of fuel injection independent of whether accessories are operated or not and without being affected by environmental conditions such as coolant temperature. The fuel injection amount learning and controlling method obtains, using an idle injection amount standard value as the standard, a fuel injection amount learning value so that the speed of an internal combustion engine (1) is a target idle speed. The method has a learning correction function that obtains in advance a relationship between load by accessories (3, 4) driven by the engine (1) and a fuel injection incremental amount that is due to the load imposed by the accessories (3, 4) and is relative to a no-load condition as the standard.Type: GrantFiled: December 8, 2006Date of Patent: March 22, 2011Assignee: Isuzu Motors LimitedInventor: Kazumi Yamaguchi

Patent number: 7895701Abstract: An opposite type wiper apparatus which can prevent interference of each wiper blade even if reference position data is lost. When at least one of reference position data memory sections is in abnormal condition, angle range calculation sections correct operation angle ranges of a DR-side and an AS-side wiper motor so as to shift an upper and a lower reversal positions of a DR-side and an AS-side wiper blade toward storage positions, and so as to make a correction value from the AS-side angle range calculation section larger than a correction value from the DR-side angle range calculation section. Therefore, even when reference position data individually memorized in reference position data memory sections are lost, the DR-side and the AS-side wiper blades can be prevented from interfering with each other.Type: GrantFiled: November 11, 2008Date of Patent: March 1, 2011Assignees: MITSUBA Corporation, Honda Motor Co., Ltd.Inventors: Toshiyuki Amagasa, Takashi Kondo, Toru Namiki

Patent number: 7895728Abstract: A tubular elastomer actuator with a shape in a cross-sectional view which shape exposes at most one single axis of symmetry of a specific length, e.g., an oval shape. The actuator could be made from a sheet made from a plurality of plate shaped elements which are laminated together and rolled. Each plate shaped element may have a corrugation that gives the element an anisotropic structure, and contains an electrode on only one surface. The actuator displacement is the result of shrinkage displacement of the plate shaped elements upon the application of electrical field across their thickness.Type: GrantFiled: August 6, 2007Date of Patent: March 1, 2011Assignee: Danfoss A/SInventors: Mohamed Yahia Benslimane, Peter Gravesen
