Title: Method and apparatus for debugging and tuning a process control network having distributed control functions
Inventor: BROWN LARRY K
IPC: G05B19/418
Filed: 1997-09-26
Granted: 2006-03-21
Abstract: A system and method for debugging and tuning a process control network having distributed control functions implemented by a set of field devices communicatively linked over a bus include an operational scheduler that schedules the execution of each of a number of process control functions and communication functions performed by the field devices to define a process control scheme and an indicator that indicates one or more process control scheme locations at which the process control scheme is to be automatically or conditionally interrupted to thereby enable debugging and/or tuning of the process control network. A controller interrupts execution of the process control scheme at the indicated flow locations, communicates process data to a user to display the current or a past state of the process to a user and waits for user input before continuing with operation of the process control scheme. In a tuning mode, the controller delivers data pertaining to a process parameter to a tuning device or to a user which determines a new tuning parameter, such as a gain, to be used within the process control scheme based on the process parameter data.

Title: Controller for a door operator
Inventor: CRIMMINS TERENCE E
IPC: H02P27/02
Filed: 1999-04-13
Granted: 2008-07-15
Abstract: A controller for controlling a motor and other functions in a commercial door or barrier operator is described. The controller includes a unique motor start circuit for starting an AC motor which employs two dual--pole-dual-throw (DPDT) relays for activating the start coil in combination with a single triac for activating the main coil of the motor, eliminating dV/dt sensitivity. A motor start control for a door or barrier operator includes a speed governor integrated onto the controller for detecting when to shut off AC power to the start coil in a single phase motor. The integrated speed governor uses an RPM sensor for detecting the speed of the operator's limit shaft coupled to software run by the processor. Switches for operating open, close, stop and learn functions are located on the controller to facilitate installation, maintenance and programming by a service provider at the door operator. In addition, a cycle counter provides a warning when the number of barrier movements equals a predetermined, programmable number of movements.

Filed: 1999-06-21
Granted: 2002-09-03
Abstract: A scroll compressor having a suction pressure chamber into which fluid is received substantially at suction pressure and a discharge pressure chamber from which the fluid is discharged substantially at discharge pressure, including a first scroll member having a first involute wrap element projecting from a first substantially planar surface, a second scroll member having a second involute wrap element projecting from a second substantially planar surface, and third and fourth surfaces opposite the second substantially planar surface, the third and fourth surfaces respectively located in first and second planes which are spaced apart from each other and substantially parallel with the second substantially planar surface. The first and second scroll members are mutually engaged with the first involute wrap element projecting towards the second surface and the second involute wrap element projecting towards the first surface, the first surface positioned substantially parallel with the second surface whereby relative orbiting of the scroll members compresses fluids between the involute wrap elements. The engaged scroll members are in fluid communication with the suction and discharge chambers. A frame is provided having fifth and sixth surface located in different planes substantially parallel with the second substantially planar surface of the second scroll member, the fifth surface adjacent and opposed to the third surface of the second scroll member, and a sixth surface adjacent and opposed to the fourth surface of the second scroll member. A first seal is disposed between the third and fifth surfaces, the first seal in sliding engagement with one of the third and the fifth surfaces. A  second seal is disposed between the fourth and sixth surfaces, the second seal in sliding engagement with one of the fourth and the sixth surfaces. An intermediate pressure chamber is in part bounded by the third and fourth surfaces of the second scroll member, the fifth and sixth surfaces of the frame, and the first and second seals, and is in fluid communication with a source of pressure intermediate suction and discharge pressures, whereby the first and second scroll members are at least partially urged into axial sealing engagement by forces induced by fluid pressure in the intermediate pressure chamber.

Abstract: An exit guard system automatically detects movement of a subject along an exit path in an unauthorized direction. A first video camera is positioned for video imaging movement of a subject along the path, while a second video camera images the subject for identification. Multiple video motion detectors operate in conjunction with the first video camera to determine direction of movement of a subject along the path. A CPU  operates with the video motion detectors under an exit guard program to provide a watching mode, during which frames of the second video camera are continuously grabbed and saved. Audible and/or visual alarm signaling devices are operated by the CPU in an alarm mode in response to traffic of a subject in the unauthorized direction. A video monitor displays modes of operation of the system and control devices allow operator selection and control of modes of operation of the system. Remote access to the system for control, monitoring or other purposes is provided by data modem feature. Method of using such system for guarding movement of a subject along the path is disclosed.

Abstract: In the processing of a biological reaction system, there is a need for consistently placing an amount of fluid on a slide. In order to accomplish this, the dispense chamber (412) is substantially in line with the reservoir chamber (408), the reservoir chamber piston is removed, and th e flow of fluid through the dispenser is simplified. Further, in order to operate the automated biological reaction system more reliably, the system is designed in modular pieces with higher functions performed by a host device and the execution of the staining operations performed by remote devices. Also, to reliably catalog data which is used by the automated biological reaction system, data is loaded to a memory device, which in turn is used by the operator to update the operator's databases. The generation of t he sequence of steps for the automated biological reaction device based on data loaded by the operator, including checks to determine the ability to complete the run, is provided.

Abstract: Cette invention se rapporte à un outil (10) qui est conçu pour être utilisé en situation immergée pour enfoncer des éléments d'ancrage ou de fondation, tels que des piliers (12), dans une formation souterraine immergée sous une masse d'eau. A cet effet, un corps de marteau est maintenu en position fixe dans l'alignement axial de la tête d'un pilier à enfoncer et porte un corps de réaction guidé dans son mouvement dans une direction axiale par rapport au pilier. Le corps de marteau et le corps de réaction définissent les première et seconde extrémités opposées d'une chambre d'expansion. Une charge pyrotechnique est allumée afin de créer un volume de gaz sous pression se dilatant rapidement dans la chambre d'expansion, générant ainsi une impulsion de force de pression montante qui enfonce le pilier, une impulsion de force de pression montante opposée étant appliquée au corps de réaction. Une structure d'amortissement, associée en position opérationnelle au corps de réaction, coopère avec la masse d'eau dans laquelle l'outil est immergé en utilisant l'inertie de l'eau pour résister au mouvement ascendant du corps de réaction.
