Patent number: 9452691Abstract: A transportation apparatus includes a payload receiving unit, a transportation body, and a compensation system arranged there between providing adjustment of a desired spatial relationship of a payload surface of the compensation unit. The compensation system has at least one of a first compensation unit and a second compensation unit for adjustment of the spatial relationship. The compensation units adjust the spatial relationship in different directions. Thus the compensation system maintains a desired orientation of the payload surface independent of changes of orientation of the transportation surface. Further, the compensation system substantially maintains a common point of gravity of the transportation apparatus including the payload by displacing the center of gravity of the payload receiving unit and the payload substantially opposite to a displacement of a center of gravity of the transportation apparatus.Type: GrantFiled: September 19, 2013Date of Patent: September 27, 2016Assignees: Zoomability AB, KIPAX ABInventor: Mikael Löfstrand

Patent number: 9439820Abstract: A vehicle having a multiple of level compensation systems is disclosed. The vehicle comprising a chassis having a left frame, a right frame and a base plate, a first level compensation system comprising a pivot joint for pivotably connecting the left and right frames to the base plate around a common rotational axis. A first axial distance from a left rotation axis of a left wheel pair to the rotational axis is different from at least one second axial distance from a right rotation axis of a right wheel pair to the rotational axis, such that the left and right wheel pair have at least one off-set to each other. Moreover a method for traversing stairs with such vehicle is disclosed.Type: GrantFiled: February 25, 2014Date of Patent: September 13, 2016Assignee: Zoomability ABInventors: Karri Zanderléhn, Mikael Löfstrand

Publication number: 20040039847Abstract: A server for a thin client network comprises a thin client network management and control module. The server also comprises a network interface mechanism which includes a broadband interface module and a narrowband emulation module inter-operable to provide a communications link to one or more thin client terminals on the thin client network. The management and control module is inter-operable with the network interface mechanism for providing a thin client network over a broadband network. Broadly speaking, the narrowband emulation module is superimposed on the broadband interface module to provide a network interface mechanism operable as an emulated narrowband interface. A thin client network implemented over a broadband network is also disclosed, together with a method for setting up and operating the same.Type: ApplicationFiled: May 20, 2003Publication date: February 26, 2004Applicant: Sun Microsystems, Inc.Inventors: Lars Persson, Mikael Lofstrand

Publication number: 20030208596Abstract: A system and method for delivering services in a secure manner is disclosed. The system includes a network that delivers services to end users. The network includes a service module that supports a service. The service module can deliver more than one service. The network also includes a load balancing switch to provide a virtual internet protocol address for the service. A data packet enclosing a request for the service is routed by the load balancing switch. The network also includes a distribution module coupled to the service module and routes the data packet to the load balancing switch. The network also includes a security module to determine if the data packet is authorized for the virtual internet protocol address. If so, then the service is provided to the end user. If not, security measures are taken to deny the end user access to the services.Type: ApplicationFiled: May 1, 2002Publication date: November 6, 2003Inventors: Jason T. Carolan, Mikael Lofstrand

Publication number: 20030179775Abstract: A service delivery network is disclosed for delivering a plurality of services to users on a network. The service delivery network includes a service module having one or more service domains. Each service domain supports a service to be delivered to the users. The service module also includes a load balancing switch to access the service module and the service domains in response to a request or data packet for the service. The service delivery network can have additional service modules to support other services. The service delivery network also includes a distribution module to route communications within the service delivery network. The load balancing switch routes the packet according to a virtual internet protocol address that corresponds to the service domain.Type: ApplicationFiled: March 20, 2002Publication date: September 25, 2003Inventors: Jason T.
