  • Publication number: 20140126849
    Abstract: A wheel bearing arrangement with first rolling elements, which are capable of rolling on a first inner ring, wherein the rolling elements are guided by a first roller bearing cage, and an axial spacer element is provided for spacing apart the first inner ring from a bearing element, wherein the bearing element can in particular be a second inner ring. The intention is to facilitate the complex installation of the individual parts in wheel bearings for utility vehicles. The first rolling element cage forms, together with the axial spacer element, an axial form-fitting connection. The spacer element can be fixed to at least one of the inner rings via the form-fitting connection to the cage prior to tightening the wheel hub, together with the wheel bearing preinstalled thereon.

  • Patent number: 8696211
    Abstract: A compact cassette seal and a corresponding wheel hearing for a passenger car or truck. The cassette seal has a bent sheet-metal ring which is and/or can be non-rotatably connected to a radially inner component and an annular sealing system which is non-rotatably connected to a radially outer component. The sealing system has a bearing ring and a radially peripheral seal with at least one sealing lip. The seal is secured to the bearing ring and the sealing lips resting on the bent sheet-metal ring in a sealing manner. A radially outer ring end section of the sealing system defines a labyrinth seal with a bent sheet-metal section of the bent sheet-metal ring. The bent sheet-metal section radially overlaps the ring end section on the exterior thereby forming an axially aligned or substantially axially aligned labyrinth seal section of the labyrinth seal.

  • Publication number: 20140003758
    Abstract: A roller bearing cage 16 with roller bearing pockets 18 which are arranged one next to the other in the circumferential direction and have the purpose of holding load-bearing roller bodies 10 of a roller bearing, wherein at least one end piece 14 which engages behind a roller bearing component 12 is formed on the roller bearing cage 16. The end piece 14, which is ideally embodied as a retaining claw, holds the inner ring and the roller body 10 together, but can be removed after or during the assembly by means of a predetermined rupture point 15, in order to make room for a further component, such as for example a sealing arrangement. As a result, despite the installation assistance, optimum use of the installation space is provided.

  • Publication number: 20130335059
    Abstract: A voltage regulator for one or more dies in a multi-stack integrated circuit includes an inductor located on a die, a voltage controller that is electrically coupled to the inductor and is also located on the die, and a capacitor that is electrically coupled to the inductor and the voltage controller and is also located on the die. The inductor defines an interior space and the voltage controller and the capacitor are located within the interior space of the inductor. The inductor can be a lateral inductor or a through layer via inductor. The multi-stack integrated circuit may have multiple dies. A voltage controller may be electrically coupled to each of the dies, although it may be located on only one of the dies. Alternatively, separate voltage controllers may be electrically coupled to each of the multiple dies and may be located on each of the respective dies.

  • Patent number: 8547769
    Abstract: Multiple dies can be stacked in what are commonly referred to as three-dimensional modules (or “stacks”) with interconnections between the dies, resulting in an IC module with increased circuit component capacity. Such structures can result in lower parasitics for charge transport to different components throughout the various different layers. In some embodiments, the present invention provides efficient power distribution approaches for supplying power to components in the different layers. For example, voltage levels for global supply rails may be increased to reduce required current densities for a given power objective.

  • Publication number: 20130246734
    Abstract: A system monitors and dynamically changes memory mapping in a runtime of a computing system. The computing system has various memory resources, and multiple possible mappings that indicate how data is to be stored in and subsequently accessed from the memory resources. The performance of each memory mapping may be different under different runtime or load conditions of the computing device. A memory controller can monitor runtime performance of the current memory mapping and dynamically change memory mappings at runtime based on monitored or observed performance of the memory mappings. The performance monitoring can be modified for any of a number of different granularities possible within the system, from the byte level to memory channel.
