Patent number: 10039239Abstract: A stump cutter controller and operator presence system includes one or more capacitive sensors in each of the three control levers that control movement of the cutter wheel. A sensor circuit measures changes in the capacitance of the sensors. The controller automatically disengages a drive clutch and applies a brake to the cutter wheel when the controller senses that an operator has left the operating station—which is assumed when the operator has not touched any one of the three control levers of the operator station for a predetermined time. The controller logic is set to allow the clutch to remain engaged during a delay period, of predetermined duration, to permit the operator to move a hand off of one control lever to another control lever. Also, a grace period, of varying duration based on the speed of the cutter wheel, may be provided during which the clutch is reengaged if an operator returns to the controls.Type: GrantFiled: July 29, 2008Date of Patent: August 7, 2018Assignee: VERMEER MANUFACTURING COMPANYInventors: Ivan R. Brand, Brent Allen Bartels, John R. Powers, Douglas E. Ammons

Patent number: 7493854Abstract: The present disclosure concerns a jam detection and safety system for machines prone to jamming, such as a baler. In particular embodiments, the system is implemented in a horizontal baler having a shear bar and a hydraulic ram that advances material being baled past the shear bar into a compression chamber. The system includes a strain gage mounted on the shear bar and a controller that is electrically connected to the strain gage. The controller receives strain signals from the stage gage and compares the strain of the shear bar to a predetermined strain threshold corresponding to a jamming condition. If the strain exceeds the predetermined threshold, the controller automatically deactivates the ram, such as by disconnecting line power from the baler and/or by turning off the control power of the baler.Type: GrantFiled: November 6, 2006Date of Patent: February 24, 2009Assignees: The Government of the United States of America as represented by the Secretary of the Department of Health and Human Services, West Virginia UniversityInventors: John R.

Patent number: 6897783Abstract: A personal electrical injury protection system is provided which can be worn by electricians, construction workers, or other individuals working around or with low-voltage lines (i.e. generally less than about 600 volts). The personal electrical injury protection system has both a proximity warning component which provides a warning of potential electrical hazards upon close approach to the low-voltage power line and an electrical contact protection component which turns off the power upon actual electrical contact with the power line. The present personal electrical protection system relies on a radio frequency transmitter attached to the worker or person to be protected and a radio receiver/controller connected to the power line. The radio frequency transmitter has a low frequency generator which is used for electrical-contact protection and a high frequency generator which is used for proximity warning.Type: GrantFiled: February 23, 2001Date of Patent: May 24, 2005Assignee: The United States of America as represented by the Department of Health and Human ServicesInventors: Shengke Zeng, John R. Powers, Jr., Larry L. Jackson, David L. Conover

Method and apparatus for determining window order when one of multiple displayed windows is selected
Patent number: 5602996Abstract: The display system includes at least one central processing unit (CPU) which is coupled through appropriate input/output (I/O) circuitry to input devices, such as a keyboard, digital pad, mouse and/or trackball. The CPU is coupled to a hard disk drive for the storage of programs and data, and may also be coupled to a network through which the CPU may communicate with a variety of other system resources and devices. The CPU is further coupled to a display device such as a CRT or liquid crystal display, on which the present invention is displayed. The windows include defined areas having window features such as menu bars, command options, text, icons and/or button functions to be executed by the CPU. The help system includes an access window having topics, index and look for button functions for selection by a user. Through the use of the topics, index or look for functions, a help inquiry is defined which results in the CPU generating and displaying a presentation window on the display.Type: GrantFiled: June 7, 1995Date of Patent: February 11, 1997Assignee: Apple Computer, Inc.Inventors: John R.

Patent number: 5600779Abstract: A user interface includes an object oriented graphic user interface having overlapping windows and provides an access window having topics, index and look for button functions for selection by a user. Through the use of the topics, index or look for functions, a help inquiry is defined. The selection of one of the button functions results in the generation and display of entries in a predefined area of the access window. Upon the selection of one of the entries by a user, phrases related to the selected entry are displayed in a working area of the access window. The selection of one of the phrases results in the display of a presentation window containing help instruction data to guide the user in the particular help task specified by the entry and phrase selection. To further assist the user, visual cues in the form of coach marks are generated for identifying features on the display which relate to the information disposed within the presentation window, but may identify any feature on the display.Type: GrantFiled: June 7, 1995Date of Patent: February 4, 1997Assignee: Apple Computer, Inc.Inventors: James E.

Patent number: 5428731Abstract: An engine for the interactive delivery and presentation of multimedia data. The delivery mechanism is premised on a topic and panel metaphor. A topic is comprised of a series of panels. Each panel further defines the multimedia data which will be used when the panel is displayed. Each panel may also contain control and qualifier elements which are used to determine the next panel to be displayed. Control elements are used to solicit information from the user. The information is then used by the qualifier elements in determining the next panel to be displayed. Each element is stored in a database as a discrete object. This allows sharing of objects amongst different panels or topics. Prior to delivery and presentation of the data, the topic must be set-up. Set-up occurs by retrieving all the necessary panel, control qualifier and data descriptor objects. The actual data associated with multimedia data objects is only retrieved when the data is to be displayed.Type: GrantFiled: May 10, 1993Date of Patent: June 27, 1995Assignee: Apple Computer, Inc.Inventor: John R. Powers, III

Patent number: 4889739Abstract: A method for obtaining commercial feed juices having textural, aroma and flavor properties more like hand-squeezed orange juice is disclosed. This method involves gentle extraction of orange fruit with commercial juice extractors, gentle and quick removal of rag, seeds and peel from the extracted juice, substantially complete removal of sensible pulp, and removal of at least some of the sinking pulp. The feed juices obtained have a relatively low viscosity and sinking pulp level, minimized levels of peel oil and flavanoid glycosides and a relatively high ratio of more desirable orange compounds to less desirable orange compounds.Type: GrantFiled: May 18, 1987Date of Patent: December 26, 1989Assignee: The Procter & Gamble CompanyInventors: John R.

Patent number: 4196134Abstract: Disclosed herein are compounds of the general formula ##STR1## wherein x and y are integers from 3 to 9, x and y together equal 12, one Z is hydrogen and the other Z is a carboxylic acid group, and R.sub.1 and R.sub.2 are fatty acid groups. A process for introducing approximately one carboxylic acid group per triglyceride molecule in vegetable oils has been developed, and the resulting acid adduct forms soaps with attractive properties. The process comprises first conjugation of the double bonds of the nonconjugated polyunsaturated groups present in the fatty acid ester and elaidinization with a catalyst, such as iodine, and then adduct formation with acrylic acid to form the compounds of the general formula. This process also greatly stabilizes the triglyceride against atmospheric oxidation and polymerization reactions.Type: GrantFiled: November 24, 1978Date of Patent: April 1, 1980Assignee: Westvaco CorporationInventors: Frank J. Ball, John R. Powers, William G. Vardell
