Patent number: 11916444Abstract: Disclosed is a hermetic AC electric motor that includes harmonics shunting such that high frequency harmonics are shunted from the AC electric motor without the use of one or more high frequency filters in the associated motor drive. A related method of operating an AC electric motor includes shunting high frequency harmonics to a fluid passing through the AC electric motor. Also disclosed is a simplified variable speed motor drive system which eliminates the need for a filter for removing high frequency harmonics.Type: GrantFiled: May 14, 2021Date of Patent: February 27, 2024Assignee: Trane International Inc.Inventors: Richard M.

Patent number: 7366463Abstract: A radio signal relay device such as satellite is used to cover several relatively small geographical regions with relatively narrow beams as well as a relatively large geographical region with a single beam. This relatively wide beam permits legacy equipment to be used. A transmitting device in a beam transmits a signal to the relay device, which in turn retransmits the signal to a receiving device. The transmitting devices, relay device, and receiving devices synchronize communication by using a particular mode of communication which includes a band of carrier frequencies and a protocol. In addition to communicating like mode signals from a transmitter to a receiver, the relay device may be used in a dual mode communication system to translate signals from the one mode to another. A translator may direct a transmitter to modulate a signal on a different carrier frequency, convert one protocol into another protocol, or both.Type: GrantFiled: May 5, 2000Date of Patent: April 29, 2008Assignee: The DIRECTV Group, Inc.Inventors: Stephen F. Archer, Richard H. Johnson

Patent number: 7120434Abstract: A first transmitting device is used to transmit a first signal on a first carrier frequency to a relay device. The relay device receives the signal by demodulating the first carrier frequency. Subsequently, the relay device retransmits the signal by modulating a second and/or a third carrier frequency. The signal is then recovered at one or more receiving devices by demodulating the second and/or third carrier frequencies. Further, a second transmitting device transmits a second signal on a fourth carrier frequency and the relay device retransmits the signal by modulating a fifth and/or a sixth carrier frequency. The signal is then recovered at one or more receiving devices by demodulating the fifth and/or sixth carrier frequencies. The transmitting and/or receiving devices are preferably voice terminals, such as a wireless telephones or data terminals, such as portable computers.Type: GrantFiled: October 20, 2005Date of Patent: October 10, 2006Assignee: The DirecTV Group, Inc.Inventors: Farzad Talaie, John G.

Patent number: 6007664Abstract: A method is disclosed for curing epoxy adhesive between the slider head and load/gimbal suspension assemblies of a disk drive access actuator employing a concentrated pulsed heat source rather than conventional, broadly applied heat source as employed in the past, such as oven heating or UV exposure. The laser source power is delivered via an optical fiber to the slider air-bearing surface (ABS) of the slider head assembly so that with this approach, the time for curing can be minimized and accurately controlled without causing damage to the assembly, and the overall curing step in the manufacturing process is reduced in time of application. Apparatus in the form of a fixture, such as an anvil element, provides a convenient gauge and support for alignment of the laser output beam with the slider ABS to which the heat for curing is to be applied as well as provide for its heat sinking.Type: GrantFiled: July 17, 1998Date of Patent: December 28, 1999Assignee: SDL, Inc.Inventors: Dirk J.

Patent number: 5623696Abstract: The present invention constructs SCSI device support code so that it can be ported to multiple operating system environments. The present invention also allows support for a device to be coded only once, and yet be supported on multiple operating system environments. Accordingly, a method and system for supporting a plurality of devices utilized with a data processing system is disclosed. This method and system allows for a plurality of devices to be utilized on a plurality of operating system platforms. The method and system comprises receiving a request from a user for a particular device, formatting the request into at least one common packet and then providing the at least one common packet to each of the plurality of operating system platforms. In so doing, any of the plurality of operating system platforms can utilize the at least one common packet to provide a device driver for the particular device.Type: GrantFiled: May 30, 1995Date of Patent: April 22, 1997Assignee: International Business Machines CorporationInventors: Richard H.

Patent number: 5595955Abstract: A pressure and heat-sensitive composition comprising chromogen-containing pressure-rupturable microcapsules and heat-sensitive color developer useful for verification of document authenticity system when applied as a localized coating on documents, such as checks and prescriptions. Quickly striking the chromogenic composition with a fingernail or blunt object to generate pressure and heat in the coating produces a colored image by friction. The chromogenic composition possesses a fugitive characteristic, whereby the colored image gradually disappears and can be made to reappear when the chromogenic coating is again subjected to external pressure and heat. This feature can be used for repeated verification of the authenticity of the document.Type: GrantFiled: November 16, 1994Date of Patent: January 21, 1997Assignee: Wallace Computer Services, Inc.Inventors: John C.

Patent number: 5557740Abstract: A method and system for testing a device driver utilized with a data processing system is disclosed. In a first aspect, the method comprises the steps of inputting a script file to a test engine to provide a test to the device driver, compiling the test engine across multiple operating system platforms. The method also includes sending a command that indicates the test is to be provided to the device driver and sending results of the test of the device driver back to the test engine. In another aspect, a system is disclosed for testing a device driver utilized in a data processing system. The system comprises a script file for providing a test of the device driver and a test engine for receiving the test from the script file.Type: GrantFiled: May 30, 1995Date of Patent: September 17, 1996Assignee: International Business Machines CorporationInventors: Richard H.

Patent number: 5450579Abstract: A method and apparatus for error recovery in various computer data storage devices that are associated with a host computer operating system includes an error recovery module that is coupled to each device driver in the host operating system. When one of the devices reports an error in the form of sense bytes to its associated device driver, the device driver sends the sense bytes and device type identification to the error recovery module. In turn, the error recovery module generates an action token based upon the sense bytes and device type, and then correlates the action token with error recovery actions. The device driver then executes the error recovery actions. Thus, a common error recovery module can be used in conjunction with a large variety of data storage devices.Type: GrantFiled: March 24, 1994Date of Patent: September 12, 1995Assignee: International Business Machines CorporationInventor: Richard H.
