Patent number: 6896495Abstract: A reciprocating compressor that includes a cylinder block with a plurality of cylinder bores. A piston is positioned in each bore. Each piston is mounted to move in response to the a crankshaft, causing each piston to reciprocate within the cylinder bore. The compressor further includes a cylinder head which includes bores corresponding to the bores in the cylinder block. The cylinder head includes a suction port in fluid communication with a source of compressible gas and a plurality of suction plenum in the cylinder head. Protrusions or ribs extend into the suction plenum. The cylinder head also includes a discharge plenum in communication with the outlet ports of the valve plate Interposed between the cylinder head and the cylinder block is a valve plate assembly having a discharge valve, and a discharge valve retainer having a pair of radii assembled to the valve plate by snap fitting a cylinder head gasket over the discharge valve and retainer.Type: GrantFiled: May 22, 2003Date of Patent: May 24, 2005Assignee: Bristol Compressors, Inc.Inventors: Benjamin Alan Majerus, Peter Douglas Mantell, Philip Scott Leonard, David Turner Monk, John Richard Walters, Jr.

Patent number: 6865615Abstract: A method and an apparatus is presented for configuring a system bus topology dynamically. In a preferred embodiment, the system bus is a Small Computer System Interface (SCSI) bus that connects a “daisy” chain of disk drives. Two types of disk drives are used: single ended (SE) “Ultra” drives capable of 20 MHz operation and LVD (low voltage differential) “Ultra Plus” drives capable of 40 MHz operation. LVD disk drives can also function in the slower SE mode. The first drive in the chain of drives may need to be connected by a cable over three feet long. This introduces signal degradation that is often overcome by introducing redrive circuitry to boost signal quality. This is an expensive solution and a much easier solution is presented: install a jumper between the last drive in the chain and the first drive. However, if LVD bus mode is used, then this jumper solution does not work and the jumper must be removed.Type: GrantFiled: July 20, 2000Date of Patent: March 8, 2005Assignee: International Business Machines CorporationInventors: Pat Allen Buckland, Scott Leonard Daniels, Thomas R. Forrer, Jr., Daniel Eugene Pridgeon

Patent number: 6845331Abstract: A data processing system and method included within an oscilloscope for independently analyzing a signal input into the oscilloscope. The oscilloscope includes a plurality of triggering modes. A plurality of trigger parameters are specified for each of the triggering modes. Thereafter, the oscilloscope automatically analyzes the input signal, independently from any user input, utilizing each of the triggering modes and the trigger parameters specified for each of the triggering modes. The input signal includes a desired waveform and a plurality of undesired waveforms. While the oscilloscope is automatically analyzing the input signal, a determination is made regarding whether the oscilloscope triggered on one of the undesired waveforms. When it is determined that the oscilloscope triggered on one of the undesired waveforms, the undesired waveform upon which the oscilloscope triggered is stored.Type: GrantFiled: January 22, 2002Date of Patent: January 18, 2005Assignee: International Business Machines CorporationInventors: Scott Leonard Daniels, David Edward Halter

Patent number: 6598097Abstract: A method and system for performing direct memory access (DMA) transfers using operating system allocated I/O buffers provides a mechanism for device to device transfers without utilizing global system memory. Memory is allocated on a local bus to which both devices have a requested degree of affinity and transfers are performed to and from this memory. Operating system routines provide for selection of global system memory or local memory based on whether there is local memory available to which both devices have a requested degree of affinity. The memory can be deallocated after each transfer and reallocated for each subsequent transfer.Type: GrantFiled: February 29, 2000Date of Patent: July 22, 2003Assignee: International Business Machines CorporationInventors: Scott Leonard Daniels, Bruce Gerard Mealey

Publication number: 20020073328Abstract: Disclosed is a method and system for protecting electronic files from unauthorized access. The drive on which the file is stored is provided with a hardware identification code, which is unique to the drive and known only by a user to whom access to the files stored on the drive is authorized. An Operating System (OS) extension is created. The OS extension allows a user to provide a security code required to access a requested drive. OS device driver, working in conjunction with the extension of the OS checks the requested drive to determine if an access code is required, and the drive responds with the security code or a default code. The default code indicates that no user-provided access code is required, and the drive is globally accessible to users on the system. Thus, when the default code is returned by the drive, automatic access to the drive is provided.Type: ApplicationFiled: December 11, 2000Publication date: June 13, 2002Applicant: International Business Machines CorporationInventors: Scott Leonard Daniels, Danny Marvin Neal, Yat Hung Ng

Patent number: 6314401Abstract: The present invention generally includes three principal components; namely, (1) a hand held transceiver for transmitting a voice pattern while moving (e.g., driving) past an (2) infra-red receiver array which receives the transmitted voice pattern, and a (3) speech enhancement and voice verification algorithm for conducting a comparison between the transmitted voice pattern and the registered voice patterns stored in the computer's memory. The hand held transceiver includes a conventional telephone handset in which a microphone subassembly, a transceiver circuit card, and LED indicators are housed. The transceiver element, also housed in the handset, includes a 16-bit analog to digital converter for converting the analog voice pattern to a corresponding digital signal, a microprocessor, a memory unit for storing the digitized voice sample for a predetermined period of time, and an IR transceiver for transmitting the digitized voice sample.Type: GrantFiled: May 28, 1999Date of Patent: November 6, 2001Assignee: New York State Technology Enterprise CorporationInventors: Stephen T.

Patent number: 6182248Abstract: An error injection tool, connected to a bus to be tested in such a manner as not to interfere with normal operation, is employed for error detection and recovery design verification. The error injection tool is connected to the bus to be tested within a data processing system, the system is powered on, and applications simulating normal system loading are run. A desired error is then selected, and the error injection tool is actuated. The error injection tool monitors bus cycles and transactions through selected signals and, upon detecting an appropriate cycle or transaction, overdrives a selected conductor within the bus being tested to inject an error. The selected bus conductor is overdriven (forced) to a logic high or a logic low for a single clock cycle, simulating the intermittent nature of errors likely to occur during normal operation. Bus error signals are then monitored to ascertain whether the error was successfully injected.Type: GrantFiled: April 7, 1998Date of Patent: January 30, 2001Assignee: International Business Machines CorporationInventors: Cynthia Joan Armstrong, Scott Leonard Daniels, Alongkorn Kitamorn, Brian Anthony Oehlke, Richard Martin Tonry
