摘要： A mobile station or other network node transmits a request to update the quality of service associated with an existing radio access bearer. In response to the request, the radio access bearer is updated without tearing down the established radio access bearer. Some applications can be associated with one or more quality of service indicia, so that as service demands change in use of a single application, requests for quality of service updates can be transmitted by, for example, a mobile station. Updates can be initiated by other user equipment or by network nodes such as gateway GPRS support nodes. Service interruptions can be reduced by preserving a radio access bearer (RAB), which is particularly useful for a stationary mobile station that continues to communicate with the same serving GPRS support node.

摘要： A micro-machined magnetic latching switch is described. A moveable micro-machined cantilever has a magnetic material and a longitudinal axis. The cantilever has a conducting layer. A permanent magnet produces a first magnetic field, which induces a magnetization in the magnetic material. The magnetization is characterized by a magnetization vector pointing in a direction along the longitudinal axis of the cantilever. The first magnetic field is approximately perpendicular to longitudinal axis. A three-dimensional solenoid coil produces a second magnetic field to switch the cantilever between a first stable state and a second stable state. The temporary current is input to the three-dimensional solenoid coil, producing the second magnetic field such that a component of the second magnetic field parallel to the longitudinal axis changes direction of the magnetization vector. The cantilever is thereby caused to switch between the first stable state and the second stable state.

摘要： Methods and systems of assembling and making laminated electro-mechanical system (LEMS) switches are described. A plurality of structural layers are formed that include at least two structural layers that each include a flexible member. The plurality of structural layers are stacked and aligned into a stack, to form at least one switch. Each structural layer in the stack is attached to an adjacent structural layer of the stack. When the formed switch is in an “on” state, the first flexible member is in contact with the second flexible member. When making contact with the second flexible member, the second flexible member flexes in response. In a further aspect, three flexible members may be present. When the switch is in an “on” state, the first flexible member is in contact with the second and third flexible members. When making contact with the second and third flexible members, the second and third flexible members flex in response.

摘要： A micro magnetic switch includes a reference plane and a magnet located proximate to a supporting structure. The magnet produces a first magnetic field with uniformly spaced field lines approximately orthogonal to the reference plane, symmetrically spaced about a central axis, or non-uniformly spaced fields approximately orthogonal to the reference plane. The switch also includes a cantilever supported by the support structure. The cantilever has an axis of rotation lying in the reference plane and has magnetic material that makes the cantilever sensitive to the first magnetic field, such that the cantilever is configured to rotate about the axis of rotation between first and second states. The switch further includes a conductor located proximate to the supporting structure and the cantilever. The conductor is configured to conduct a current. The current produces a second magnetic field having a component approximately parallel to the reference plane and approximately perpendicular to the rotational axis of the cantilever, which causes the cantilever to switch between the first and second states. The switch still further includes a stopping device located proximate to the supporting structure. The stopping device is operable to stop the cantilever from rotating about the axis of symmetry beyond a point at which a longitudinal axis of the cantilever is approximately parallel to a longitudinal axis of the magnet.

摘要： A method, system, and apparatus for testing one or more micro-magnetic switches on a wafer is described. A magnet is positioned adjacent to a first switch on the wafer. A probe card is positioned adjacent to the first switch. The probe card mounts a first set of probes and a second set of probes. The first set of probes interface with contact areas of a coil associated with the first switch. The second set of probes interface with conductors on the wafer associated with the cantilever of the first switch. A current source is electrically coupled to the first set of probes. The current source activates the coil of the first switch using the first set of probes to switch the cantilever from a first state to a second state. A switch state monitor is electrically coupled to the second set of probes. The switch state monitor determines whether the cantilever of the first switch is in the first state prior to the current source activating the coil of the first switch. The switch state monitor also determines whether the cantilever is in the second state after the current source activates the coil of the first switch. A stepper motor moves the wafer relative to the magnet and probe card to test further switches on the wafer. An inker marks a switch on the wafer that has been determined by the switch state monitor to be defective.
