Publication number: 20020139646Abstract: The invention described herein comprises a lockout device that is permanently attached to a circuit breaker or on the panel to which the circuit breaker is attached to provide a means of physically locking the operating handle of the circuit breaker in the OFF (open) position. It includes a lockout bar that can be rotated to the unlocked position so that the operating handle can be moved to allow manual operation of the circuit breaker to either the ON (closed) or OFF (open) position. A hasp is provided to facilitate the use of a standard padlock to lock the circuit breaker in the OFF (open) position Two versions for mounting the device are included; namely, one version for locking out one or more circuit breakers in a group of circuit breakers, and a second version for locking out a single circuit breaker.Type: ApplicationFiled: April 2, 2001Publication date: October 3, 2002Inventor: Robert Frank Karlicek

Method and apparatus for performing wavelength-conversion using phosphors with light emitting diodes
Patent number: 6404125Abstract: An apparatus comprises an active region, a phosphor layer and a substrate. The active region is configured to emit light having a first band of wavelengths selected from a first group of wavelengths. The phosphor layer has a first refractive index. The phosphor layer includes a plurality of wavelength-converting phosphors. The phosphor layer is configured to convert the first band of wavelengths of light emitted from the active region to a second band of wavelengths. A center wavelength of the second band of wavelengths is greater than a center wavelength of the first band of wavelengths. The substrate is disposed between and in contact with the active region and the phosphor layer. The substrate has a second refractive index. The first refractive index substantially equals the second refractive index.Type: GrantFiled: October 20, 1999Date of Patent: June 11, 2002Assignees: Sarnoff Corporation, Emcore CorporationInventors: Dmitri Zalmanovich Garbuzov, John Charles Connolly, Robert Frank Karlicek, Jr., Ian Thomas Ferguson -
Patent number: 6366018Abstract: An apparatus, comprises an active region, a phosphor layer and a reflective layer. The active region is configured to emit light having a first band of wavelengths from a first group of wavelengths. The phosphor layer is disposed between and in contact with the active region and an exterior medium. The phosphor layer is configured to convert the first band of wavelengths of light emitted from the active region to a second band of wavelengths. A center wavelength of the second band of wavelengths is greater than a center wavelength of the first band of wavelengths. The reflective layer is optically coupled to the active region. The active region is disposed between the reflective layer and the phosphor layer. The reflective layer is configured to reflect at least the first band of wavelengths and the second band of wavelengths.Type: GrantFiled: October 20, 1999Date of Patent: April 2, 2002Assignees: Sarnoff Corporation, Emcore CorporationInventors: Dmitri Zalmanovich Garbuzov, John Charles Connolly, Robert Frank Karlicek, Jr., Ian Thomas Ferguson

Publication number: 20010035051Abstract: The system and apparatus described herein relate to the measurement of vacuum pressure using a Vacuum Sensor (thermocouple) producing a voltage that is connected by cable to a portable, battery operated Vacuum Monitor instrument which converts it to a vacuum pressure and displays it in digital format on an LCD. The Monitor automatically supplies the proper filament current required by the Sensor, and the operation of the system is controlled by a microprocessor in the Monitor. The system makes it possible to measure vacuum pressure without external power and eliminates the need for manually operated switches and manual adjustments. A Test Sensor is provided with the Monitor to enable performing a fill functional and calibration test of the Monitor.Type: ApplicationFiled: March 12, 2001Publication date: November 1, 2001Inventor: Robert Frank Karlicek

Patent number: 6222863Abstract: A stable, reliable ohmic contact, and improved semiconductor articles and opto-electronic circuits incorporating same, are disclosed. According to an illustrative embodiment of the invention, an ohmic contact having a plurality of thermodynamically-stable layers and layer interfaces is formed by providing a structure comprising multiple, appropriately-thick and specifically-organized layers of suitably-selected material, and exposing the structure to heat to cause reaction to take place between the various layers. Due to the thermodynamic stability of the resulting reacted layers and the interfaces between such layers, there is substantially no tendency for further reaction to occur within the ohmic contact.Type: GrantFiled: January 31, 1998Date of Patent: April 24, 2001Assignee: Lucent Technologies, Inc.Inventors: Gustav Edward Derkits, Jr., Marlin Wilbert Focht, Daniel Paul Wilt, Robert Frank Karlicek, Jr.
