The user equipment is enabled with a simple clock discipliner that adjusts the local clock to the global clock, resulting in a reliable synchronization across the converged communication networks.

Liquid infusion apparatus includes non-magnetic materials in a pumping structure and ultrasonic drive motor therefor, and in a controller that supplies drive signals to the motor to facilitate convenient operation in intense magnetic fields without distorting the magnetic fields and without radiating objectionable radio-frequency interference. A non-MRI-compatible liquid infusion apparatus is temporarily replaced with MRI-compatible, non-magnetic liquid infusion apparatus without disconnecting a patient from an installed intravenous infusion set to continue infusing liquid within the MRI environment. The pumping apparatus operates on a segment of a liquid conduit that is mounted in tension between a linear peristaltic pump and platen, with associated safety interlocks to assure proper operation of infusing liquid into a patient compatibly with conditions in an MRI environment. Drive circuitry generates low-harmonic signals for operating the ultrasonic motor at variable speeds to compensate for flow rate discontinuities through the peristaltic pumping cycles.

A high-speed shift register circuit is provided. The shift register circuit includes a first transistor supplying a clock signal to a first output terminal, a second transistor discharging the first output terminal, a third transistor supplying the above clock signal to a second output terminal, and a fourth transistor discharging the second output terminal. The gates of the first and third transistors are both connected to a first node, and the gates of the second and fourth transistors are both connected to a second node. The first node is charged by a fifth transistor which is connected between the first node and a first input terminal and which has a gate connected to a second input end.

In a switching power converter, PWM mode and PFM mode are separated into two independent control sections with the control voltage range in each control section determined independently. Each of the PWM and PFM modulation modes cannot operate continuously beyond its boundaries, thereby forming a control gap between the two control sections within which no continuous operation is allowed. In order to supply a load condition within the control gap, the power supply operates at the two boundaries of the control gap. Transition between PWM and PFM modes occurs fast, with low output voltage ripple. No limitation needs to be imposed on the control voltage range in each of the PWM and PFM control sections, because the control parameters in the PWM and PFM control sections need not be matched to one another, due to separation of the PWM and PFM modes by the control gap.

The present invention provides a portable device for enhancing circulation in a limb comprising at least one strap for encircling the limb, a motor and a mechanism driven by said motor for intermittently actuating a first transition from a relaxed state to a strained state of the strap and a second transition from the strained state to the relaxed state. The mechanism includes at least one energy storing element operatively disposed between the motor and the strap and at least one energy releasing mechanism coupling between the energy storing element and the strap. The energy releasing mechanism enables fast release of energy stored in said storing element and the use of the energy so released to effectuate at least one abrupt transition between said relaxed and strained states.

By obtaining the address of a circuit switching controller in the a network with which a mobile station is registered, a packet call controller instructs the circuit switching controller to send notification of when a handoff request is received for a mobile station by the circuit switching controller. The handoff request is for transferring a packet switched call to the circuit switching controller as a circuit switched call. The notification request includes an identifier, which the circuit switching controller uses in notifying the packet call controller of the handoff request. In response to the notification, the packet call controller re-establishes call control and bearer paths between the call endpoints.

Fast transitions between access points (APs) in a wireless network may be accomplished when a mobile unit (MU) moves between the APs, by causing a first tunnel to be established between the APs, and causing a second tunnel to be established between the new AP and the MU. A data path having established security and quality of service parameters between the MU and the old AP may be extended through the tunnels, so that communication with the MU is not disrupted while transitioning between APs. Transition processing thus may be decoupled from movement of the MU, so that the MU may continue to receive access to data over the data path. Optionally, once the data path has been so extended, the MU and new AP may engage in authentication and other messaging to formally affect a handover of the data path to the new AP. The APs and MU may be configured to communicate according to the 802.11 protocol.

A method of reducing noise in an audio signal, comprising the steps of: using a furrow filter to select spectral components that are narrow in frequency but relatively broad in time; using a bar filter to select spectral components that are broad in frequency but relatively narrow in time; analyzing the relative energy distribution between the output of the furrow and bar filters to determine the optimal proportion of spectral components for the output signal; and reconstructing the audio signal to generate the output signal. A second pair of time-frequency filters may be used to further improve intelligibility of the output signal. The temporal relationship between the furrow filter output and the bar filter output may be monitored so that the fricative components are allowed primarily at boundaries between intervals with no voiced signal present and intervals with voice components.

Synchronizing uplink and downlink transmissions by a wireless user equipment (UE) device. A connection with a network may be established via a wireless link with a cell. The UE may operate in an active state during first periods of time in which uplink or downlink communications may be performed between the UE and the network. The UE may operate in a reduced-power state during second periods of time in which uplink and downlink communications are not performed. The first periods of time may alternate with the second periods of time in a repeating manner. Uplink data generated by the UE may be buffered during second periods of time and transmitted during first periods of time. Buffering uplink data in this manner may prevent the UE from immediately transitioning from the reduced-power state to the active state to transmit uplink data, which may conserve battery of the UE.
