Patent number: 6583657Abstract: A duty cycle correction circuit is configured to adjust the duty cycle of a clock signal in a clock distribution network. The duty cycle correction circuit adjusts the duty cycle of the clock signal by adjusting the transitional delay in a single edge of each clock pulse of the clock signal without interrupting the other edge of each clock pulse of the clock signal. This feature enables the duty cycle correction circuit to adjust the duty cycle of the clock signal without interrupting the operation of a phase-locked loop (PLL) used in the clock distribution network. The duty cycle correction circuit includes a delay-control circuit coupled to a clock-inverter circuit. The delay-control circuit generates a delay-control voltage, which is provided to the clock-inverter circuit to control the transitional delay in a single edge of each clock pulse of the clock signal.Type: GrantFiled: June 20, 2002Date of Patent: June 24, 2003Assignee: International Business Machines CorporationInventors: James Patrick Eckhardt, Byron Lee Krauter

Patent number: 6578987Abstract: A stage lighting instrument having a high-intensity light source or lamp coupled with a concave reflector, and a projection optical system having a lens system that includes a well-defined aperture stop. The lens system forms a real image of the light source near the aperture stop. A color filter and dimming system may be located within the lens system so that the color filter and dimming elements occupy a volume of space near the aperture stop and within the real image of the light source. By locating the color and dimming apparatus near the aperture stop and within the volume occupied by a real image of the light source, superior color mixing, dimming and integration is achieved using simple, unpatterned filters and a simply-shaped dimmer panel. A color filter and dimming system may alternatively be located as close to the light source as possible so that a real image of the color filter and dimming elements is formed near the aperture stop where the image of the light source is formed.Type: GrantFiled: May 3, 2000Date of Patent: June 17, 2003Assignee: Vari-Lite, Inc.Inventors: Thomas A.

Patent number: 6553508Abstract: Disclosed is a method and apparatus for providing fault tolerance in Totem Networks by use of redundant fabrics. The above is accomplished in one embodiment of the invention by operating devices on the network in such a way that the devices mark the token to indicate when the token has been switched from one fabric to another in response to a timeout. A Ring Master device on the network determines, based on switching of the token by devices on the network whether a fabric or device on a fabric of the network has failed. In addition, fabrics that have failed are monitored to determine when they have become operational. Retransmission of improperly received messages as per token-message-order protocols are also provided for situations in which the token is received before all messages intended for a given device have been properly received.Type: GrantFiled: December 31, 1999Date of Patent: April 22, 2003Assignee: Nortel Networks LimitedInventor: Trenton Corey Minyard

Patent number: 6507741Abstract: An RF repeater having a fixed or adjustable time delay inserted in the reverse path and/or forward path of the RF repeater is used in a first cell for improving hard handoff performance from the first cell to a second cell. Certain factors associated with the CDMA hard hand-off process effectively reduce the coverage area of the first cell, including the round-trip delay (RTD) uncertainty, the time needed to perform the hard hand-off process, and a higher forward link Eb/No requirement. Use of an RF repeater in accordance with the increases the effective coverage area of the first cell. The delayed signal from the RF repeater also allows the base station to determine the location of the subscriber station thereby identifying the particular adjacent cell to which the subscriber station will be switched (hard hand-off).Type: GrantFiled: December 17, 1997Date of Patent: January 14, 2003Assignee: Nortel Networks LimitedInventor: Farhad Bassirat

Patent number: 6496496Abstract: Disclosed is an apparatus and method of increasing the likelihood of successful and quick reception of messages containing crucial data in a CDMA cellular communication system. The data may be transmitted at a lower frame rate than normal messages but at the same power level as used for normal messages in full rate frames to raise the signal to noise ratio at the receiver. An abbreviated version of the message containing only the critical parameters may be sent to lessen the likelihood of a bit being incorrectly decoded as well as shortening both the time of transmission and receipt. The two approaches may be combined and the abbreviated message may be supplemental to the normal message. Specifically, the use of a short version of a handoff direction message using only the parameters required for a soft-handoff between cells within a system is described in detail.Type: GrantFiled: April 22, 1999Date of Patent: December 17, 2002Assignee: Nortel Networks LimitedInventors: Deepa Ramakrishna, Ahmad Jalali

Patent number: 6452865Abstract: A single common symmetrical DDR read data path structure and corresponding storage addressing scheme is provided for implementing both N-bit and (N/2)-bit interfaces to a DDR memory. The read data path structure of the present invention uses a feedback loop of a lower data path to a higher data path in conjunction with the translation of the physical addressing of the data stored into a memory. The feedback loop and address translation mechanism is enabled for (N/2)-bit mode and disabled for N-bit mode. Normally, a multiplexer controlled by a static control is used to change the bit mode.Type: GrantFiled: August 9, 2001Date of Patent: September 17, 2002Assignee: International Business Machines CorporationInventor: Barry Joe Wolford
