Filed:

May 11, 2011

Appl. No.:

13/105762

Inventors:

William C. Berg - Lakeville MN, US
Matthew J. Loegering - Edina MN, US

Assignee:

Analog Technologies Corporation - Lakeville MN

International Classification:

H05B 37/00

US Classification:

315185R, 315312, 315307, 315291

Abstract:

This application relates to the systems and methods for networking and control of lighting systems. In particular, this application relates to the addressing and control of light emitting diodes (LEDs) connected serially on a bus within a network of serially bussed LEDs. The approaches described in this application simplify and lower the cost of control by distributing the control functions between a serial bus controller and controllers associated with individual LEDs or LED circuits on the serial bus. Hardware intensive decoding of predefined addresses, or time consuming address processing and determining algorithms, are not employed. Instead, the addressing method disclosed both simplifies the system by reducing hardware requirements and improves the speed of the data packets and reduces packet latency moving down the serial bus.

International Classification:

F21V 7/20

US Classification:

362345, 362346, 362320, 362323, 362218

Abstract:

A light emitting diode (LED) lighting system and method is inherently configurable into a variety of new and retrofit lamp applications. This reduces fixture costs by incorporating the heat removal method, light guide system, and a chassis into one easy to assemble and install structure. It also allows for configuration of a lighting system for determining overall height, overall inner and outer radii, light directivity, lighting intensity, and thermal performance. In retrofit applications, the lighting system can be configured to minimize installation costs. In a preferred embodiment, a LED lighting system is comprised of sub assemblies of LED circuit strips or arrays conjoined to create a multifaceted structure. Each sub-assembly has LEDs mounted on a circuit substrate with conductors to electrically connect the LEDs. These circuits are thermally interfaced and attached to thermally conductive material selected, treated, or processed to obtain desired light reflecting properties.

Appl. No.:

6/207515

Inventors:

William E. Berg - Prior Lake MN

Assignee:

Tektronix, Inc. - Beaverton OR

International Classification:

H01R 909

US Classification:

339 17CF

Abstract:

This disclosure describes an electrical connector for joining microcircuit or microcircuit modules, such as leadless integrated or hybrid circuit carriers to utilization means, such as printed or etched circuit boards or similar means. The electrical contacts through which the microcircuit and utilization means are connected are formed and etched in place on an elastomeric material, precisely located; the material acting as a restoring force to maintain connection. The connector when used in a system maintains transmission line mediums in a single environment.

International Classification:

F28F 700
F24H 306
H05K 720

US Classification:

165 803

Abstract:

The present invention relates to an improved system and method for cooling electronic devices. The present system is particularly adapted for cooling computer equipment. The system comprises a sealed enclosure which houses one or more heat generating electronic devices; a blower; and a heat exchanger. The sealed enclosure may be pressurized with a gas medium such as dry nitrogen up to a pressure of approximately two atmospheres. The elevated pressure increases the gas density, effectively increasing the mass flow rate and heat carrying capacity of the gas. The blower is also a constant volume device such that it can move the same volume of gas regardless of density. Accordingly, for a given heat load, the size of the blower may be reduced. Or, alternatively, a given blower can cool a device having a higher heat load. Finally, by pressurizing the enclosure, the present invention eliminates the need to size a forced air cooling system based on high elevation requirements.

Assignee:

International Classification:

A61N 139

US Classification:

607 5

Abstract:

A battery powered cardioverter or defibrillator employing a DC-DC converter for charging high voltage output capacitors and for delivering biphasic cardioversion or defibrillation pulses through a bridge circuit including high and low side drive circuits under the control of a microprocessor controlled arrhythmia detection system. Upon the detection of an arrhythmia and the selection of cardioversion/defibrillation therapy, the charging of the high voltage output capacitors is commenced and the capacitor voltage enables a regulated voltage source for the high and low side drive circuits for the high power IGTs of each branch of the bridge circuit. High voltage switching transients are suppressed from re-triggering or otherwise affecting operation of the drive circuits. Fail safe circuitry disables operation of the drive circuits in the event that the first and second control signals are inadvertently provided simultaneously or overlap.
