US Patent:

6700352, Mar 2, 2004

Filed:

Nov 10, 2000

Appl. No.:

09/710020

Inventors:

Stephen Elliott - Bradenton FL
Robert Mylott - Bradenton FL

Assignee:

Radiant Power Corp. - Palmetto FL

International Classification:

H02J 700

US Classification:

320130, 320131

Abstract:

A power charger which charges and provide conditioned power from at least one of a super-capacitor and a secondary battery. The type of energy device is user selectable, such that the user can select super-capacitors because of their much longer charge/discharge life and low-maintenance requirements, while another user can chose secondary batteries because of their higher stored energy, while a third user may select a combination of the two.

Assignee:

Radiant Power Corporation - Sarasota FL

International Classification:

H02H003/00

US Classification:

361 62, 361 64, 307 29

Abstract:

A SkyCharger™ Node or “Node” that contains programmed instructions and/or “intelligence” for monitoring communication traffic on a communications network such that appropriate reactions to commands received over the communications network occurs. The “Nodes” also broadcast commands and status information to the network for the purpose of being monitored and/or responded to by other “Nodes” on the network. The “Nodes” provide a way to monitor, control, provide information to or from, or react to, information provided by way of SkyCharger™ network(s).

Appl. No.:

10/770355

Inventors:

Stephen Elliott - Bradenton FL, US

International Classification:

H05B037/02

US Classification:

315247000, 315224000, 315291000

Abstract:

The light output intensity of incandescent lamps and LEDs connected to a common lamp power bus are controlled using a composite waveform having two power components: a pulse-width modulated (PWM) component and a direct current DC component. The DC component is maintained below the turn-on voltage for the LEDs. The PWM component controls the light intensity of the LEDs; and the DC component is calculated as a quadrature power series, taking into account that the PWM component contributes to the light intensity of the incandescent lamps. The frequency and slew rate of the PWM component are selected to minimize EMI. A small steady state power component is provided to keep the LEDs slightly turned on to minimize EMI.

Assignee:

Trilectron Industies, Inc. - Palmetto FL

International Classification:

H02H 300

US Classification:

361 42

Abstract:

A ground fault and over-voltage detector and method is disclosed for sensing a loss of neutral continuity between the respective neutral conductors of a ground power unit and an aircraft power system coupled to the unit. The detector includes a feedback path for carrying a feedback signal from the aircraft to the ground power unit. The feedback signal comprises a voltage signal referenced to the aircraft neutral and includes a ground fault voltage component. The detector further includes a signal conditioner disposed in the ground power unit for receiving the feedback signal and generating a signal representative of the magnitude of the ground fault voltage component. A comparator connected to the output of the signal conditioner contrasts the ground fault voltage magnitude signal to a predetermined threshold and a cutoff mechanism responsive to the comparator, when the ground fault voltage is greater than the threshold, to interrupt ground power from the ground power unit to the aircraft.

Appl. No.:

9/097201

Inventors:

Stephen H. Elliott - Bradenton FL

Assignee:

Trilectron Industries, Inc. - Miami FL

International Classification:

G05F 140

US Classification:

323269

Abstract:

A current sharing apparatus for use in a power device system having a plurality of power devices disposed in parallel relationship. The power devices each include a programmable current source, a capacitive element coupled to the current source to generate a reference voltage, a power device configured to generate an output voltage following that of the reference voltage, and a slew rate controller. The controller has an input disposed in sensed communication with the output voltage to generate an error signal and control current from the current source. The current sharing apparatus includes a system output drawer connected to the respective power supply outputs to collect a total system output and a system output detector coupled to the system output drawer. The detector measures the total output through the drawer and is operative to generate a signal indicative of the total output and feed the signal to the respective slew rate controller inputs to further modify the error signals. The respective slew rate controllers are each independently operative to compare the system output to the corresponding power device outputs and, when the corresponding power device output is less than a predetermined fraction of the system output, to increase the corresponding power device output.

Inventors:

Stephen H. Elliott - Bradenton FL

Assignee:

Trilectron Industries, Inc. - Miami FL

International Classification:

G05F 156

US Classification:

323280

Abstract:

A power supply with a programmable voltage slew rate is disclosed for generating a regulated voltage at a predetermined set-point. The power supply includes a programmable current source for generating a controllable level of current flow and a capacitive element coupled to the current source. The capacitive element is responsive to the current flow to establish a reference voltage that varies linearly with respect to variations in the current flow. The power supply additionally includes a power device having a control element disposed in sensed communication with the reference voltage and an output for driving a load. The output is operative to generate an output voltage following that of the reference voltage.

Abstract:

An electrical generation system. A floating vessel is anchored in flowing water. Inlets in the hull of the vessel capture flowing water and direct the water to one or more turbines. The system is designed so that all flows are two-dimensional to the extent possible. The latter feature greatly simplifies both design and construction.
