The method comprises: generating a stimulation signal comprising a plurality of pulse bursts each comprising a plurality of pulses; and distributing said plurality of pulse bursts across one or more electrodes each operatively coupled to nerve or tissue fibers such that each of said plurality of pulse bursts delivers a charge to said nerve or tissue fibers to cause dispersed firing in said nerve or tissue fibers.

A method and system for bladder control are disclosed. In embodiments, a method for bladder control is provided that comprises coupling an electrode to an afferent nerve that is related to the bladder. Applying a plurality of pulse burst stimulations via the electrode causes voiding of urine from the bladder. In embodiments, the plurality of pulse burst stimulations to the afferent nerve reduces external urethral sphincter (EUS) contractions and evokes bladder contractions to expel urine from the subject. In embodiments, the plurality of pulse burst stimulations to the afferent nerve evokes bladder contractions alone to expel urine from the subject. In embodiments, a system for bladder control is provided that comprises an electrode for applying a pulse burst stimulus to an afferent nerve or dermatome to reduce reflex contractions and a signal generator for generating the pulse burst stimulus.

A resonant switching power converter having burst mode transitioning operates during low or zero load conditions with reduced audible noise and component stresses, while improving efficiency. Pulse bursts are generated with a beginning and / or ending pulse duration that differs from mid-burst pulse durations, in order to reduce an amplitude of transients otherwise generated at the beginning and / or end of the bursts. Alternatively, the spacing between the pulses at the beginning and / or end of the bursts may differ from the spacing between the pulses in the middle of the bursts to reduce the transient(s). A number of pulses at the beginning and / or end of the burst can also be set with gradually varying durations, to further reduce component stress and audible vibration in a transformer that couples the resonant tank to the output of the converter.

In a mobile environment, a mobile device includes an attached memory stick (removable memory) having a high speed—memory and storage with direct memory access embodied in an integrated circuit chip coupled to an ultra-wideband (UWB) transceiver. The mobile device communicates with other like base devices, portable or stationary, via UWB transmissions using pulse bursts up to 1 Gbit per second. Data transfers between the devices occur in the simplex or duplex mode, after a low power communication connection is established between the devices. The communication link between the devices is in the range of 10-20 meters. The communication system allows existing device bus interfaces (which are much slower than ultra-wideband transmissions) to communicate between the fast read / write cycles of the memories integrated within the memory stick. Duplex transmission can occur by pulse interleaving sending side transmitters and receiving side transmitters.

Output pulses from an optical system having a seed source and an optical amplifier coupled to the seed source may be controlled by controlling a power of a seed signal from the seed source. The seed signal may be varied between a minimum value and a maximum value in a way that the seed signal exhibits one or more pulse bursts. Each pulse burst may contain one or more pulses. During an inter-pulse period between successive pulses within a pulse burst or between successive pulse bursts, the power of the seed signal may be adjusted to an intermediate value that is greater than the minimum value and less than the maximum value. The intermediate value is chosen to control a gain in the optical amplifier such that a pulse or pulse burst that follows the period exhibits a desired behavior.

Pulse width modulation is provided for controlling a resonant power converter, particularly for dimming of light emitting diode arrays without loss of efficiency. Dynamic oscillation due to the beginning of a pulse width modulated pulse burst is limited by shortening of the first and / or last pulse of a pulse bust such that the first pulse of a subsequent pulse burst close to or to connect with a full load steady-state voltage / current trajectory of the power converter. Pulse shortening made be made substantially exact to virtually eliminate dynamic oscillation but substantial reduction in dynamic oscillation is provided if inexact or even performed randomly.

A circuit assembly controlling an optical system to generate optical pulses is provided. The optical system includes a seed light source optically coupled to an amplitude modulator. The circuit assembly includes a control circuit which generates a pulsed seed drive signal for driving the seed laser source, as well as logic signals defining successions of ON and OFF states and having a predetermined relative timing relationship. One or more of the logic signals is delayed by a corresponding programmable delay line to adjust the relative timing relationship between the logic signals. A logic gating module combines the logic signals according to one or more logical rule, thereby providing a modulator drive signal. Using this circuit assembly, the optical system outputs an optical pulse at each ON state of the modulator drive signal synchronized with the passage of one of the seed optical pulses through the amplitude modulator.
