An anchor member is located at a distal portion of the lead, and the lead includes one or more electrodes located between the device housing and the anchor member. A delivery system for implanting the medical device within the lumen includes an elongated delivery device and a needle. The needle includes a bore to receive the anchor member of the medical device. The delivery system inserts the anchor member through a passageway from the lumen, through the tissue, and back into the lumen.

Abstract: Techniques for determining whether a medical device will be able to deliver stimulation according to a particular program throughout a useable voltage range of a power source of the medical device are described. According to some examples, the medical device configures a DC to DC converter of the medical device in a specified output configuration and delivers electrical stimulation from the medical device according to a program while at the specified output configuration. Whether the medical device will be able to deliver stimulation according to the program when the power source is at a power source voltage level lower than a present voltage level used during therapy delivery is determined based on a value of a voltage drop across a regulator module determined while delivering the electrical stimulation according to the program. The determination for a program may be performed, as an example, when the program is created or modified.

Abstract: The invention is directed to an optical network terminal (ONT) for use in a passive optical network (PON) that provides reliable battery status reporting and, optionally, remote monitoring and configuration of an uninterruptible power supply (UPS) unit. In particular, the UPS unit provides power to the ONT via a power line and transmits data to the ONT via the power line. Generally, the described invention supports one-way or two-way communication of status, alarm, and configuration signals using a single power line. Specifically, such signals may be transmitted over the power line by inserting a carrier frequency, such as a carrier frequency of approximately 1 MHz, onto the power line. In this manner, the invention may provide a simple battery status monitoring system while also reducing the cost of installation.

Abstract: In general, techniques are described for dynamically managing weighted queues. In accordance with the techniques, a network security device comprises a queue management module that assigns, for each queue of a plurality of queues, a quota desirable to a user that a processor of the network security device consumes to service each queue. The queue management module determines, based on the desirable quotas, a queue weight for each queue and computes. Based on the computation, the queue management module dynamically adjusts one or more of the weights such that subsequent amounts of processing time actually required to process the number of packets defined by each of the queue weights more accurately reflects the desirable quotas assigned to each of the queues. The network device outputs the number of packets in accordance with the adjusted weights.
