Abstract: An implantable medical device delivers neurostimulation therapy to a patient according to a parameter set, which may consist of a number of programs that are delivered substantially simultaneously. When programming the implantable medical device for the patient, a clinician programmer may maintain a session log that includes a listing of programs delivered to the patient and rating information provided by a clinician and the patient for programs of the list. The listing may be ordered according to the rating information in order to facilitate the selection of programs for a parameter set. A program library that may include particularly effective programs may be stored in a memory. One or both of the implantable medical device and a patient programmer may store usage information that provides an objective and accurate record of therapy use by the patient, and allows a clinician to later improve the therapy based on the usage information.

Abstract: A multi-chassis network device sends state information to internal consumers within the multi-chassis device via a hierarchical distribution. As one example, a primary master routing engine within a control node of a multi-chassis router forwards state information to local routing engines within other chassis, which in turn distribute the state information to consumers on each chassis. Each local routing engine defers sending acknowledgement to the master routing engine until acknowledgements have been received from all consumers serviced by the local routing engine. Embodiments of the invention may reduce control plane data traffic and convergence times associated with distribution of state updates in the multi-chassis network device.

Abstract: A device provides layer two (L2) services between customer networks that are coupled by one or more intermediate computer networks. The device comprises a routing process that receives label information for a label switched path (LSP) through the intermediate networks. The device further comprises a L2 service that receives L2 service information from a device associated with second customer network. In accordance with the label information, the device transports L2 communications between the first and second customer networks through the one or more intermediate networks. By utilizing label information in this manner, the device may minimize the impact of providing L2 services through the intermediate networks.

Abstract: A detachable module system includes a plurality of modules that couple to a corresponding plurality of module mounts on a mounting plate. To install a selected module into the module system, a user translates the selected module to an engage position on its respective module mount to engage the selected module with a immediately preceding adjacent module. Any one of the modules may be identified and removed from its module mount, without requiring removal of the remaining modules. The modules may house various types of electronic devices.

Abstract: A therapy adjustment received from a patient is associated with a sensed patient posture state. Thereafter, a stability indication can be associated with the sensed posture state to indicate that a therapy adjustment specific to the sensed posture state was received and implemented. In addition, therapy parameter values associated with related patient posture states are updated based on the therapy adjustment. In some examples, only the related posture states that are not associated with respective stability indications are updated based on the therapy adjustment. The absence of a stability indication indicates that the patient has not inputted a therapy adjustment specific to the respective related posture state. As a result, the therapy parameter values associated with the related posture states that are not associated with stability indications may float until the patient adjusts the therapy parameter value associated with the respective related posture state.

Abstract: The disclosure describes a system that measures the distance between one or more electrodes and tissue of a patient, and controls one or more parameters of the stimulation delivered to the tissue by the electrodes based on the measured distance. The system controls the measurement of the distance between the electrodes and the tissue as a function of activity of the patient. The system uses, for example, a piezoelectric transducer to sense activity of the patient, and may determine whether or how frequently to measure the distance between electrodes and tissue based on the sensed physical activity. A piezoelectric transducer may be used both to sense activity and to measure the distance between the electrodes and the tissue.

Abstract: A network device is described in which a dedicated resource scheduler monitors memory consumption to provide for improved processing of communication sessions. The scheduler maintains a dependency list of communication sessions, and reserves memory for communication sessions as requests for memory are received. The amount of memory reserved is determined based on the amount of memory currently reserved for the communication sessions in the dependency list. The network device may control ongoing communication sessions by way of window manipulation. Communication sessions are processed in a first mode when available memory has not reached a predetermined amount, while communication sessions are processed in a second mode when available memory reaches a predetermined amount.

Abstract: This disclosure is directed to devices and methods for facilitating the upgrade of optical networks. An optical network terminal (ONT) that terminates an optical fiber link of an optical network comprises two or more transport engines that each converts data transmitted via different transports to data corresponding to a service. For example, the ONT may include a first transport engine and a second transport engine. The first transport engine converts data received over the optical network via a first transport, e.g., a legacy transport, into data corresponding to a service for one or more subscriber devices. The second transport engine converts the data received over the optical network via a second transport, e.g., a next generation transport, into the data corresponding to the service for the subscriber devices. The ONT is selectively configurable to select one of the first and second transport engines, thereby making the ONT upgrade-resilient.
