Abstract: A flowmeter (100) or mass flow controller (101) used in a manufacturing process with toxic and reactive process fluids. A fluid flow sensor (114) sensesfluid flow. A set point is established based upon predetermined temperature and pressure conditions at which the fluid will be utilized in the process. A valve drive (124) operates a fluid flow valve (126) to the resulting fluid flow rate, this being based upon the sensed flow rate and the set point. A control unit (122) controls the valve drive. The control unit accesses a calibration data set to determine the amount of fluid to be delivered by the fluid flow valve based uponthe sensed flow rate and the set point. This calibration data set is created for the controller over its operational range using a calibration fluid having similar thermodynamic transport properties to a process fluid. The instrument is calibrated using the calibration fluid and the data set is produced by converting the calibration data using process fluid data stored in a data base (200). Accessing the data set stored in the instrument together with routing signals over a communication network (300) permits the instrument to precisely control process fluids without having to introduce external correction factors or other adjustments to the process.

Title: Shielded needle assembly
Inventor: SZABO SANDOR
IPC: A61M5/32
Filed: 1997-06-12
Granted: 2001-03-20
Abstract: A shielded needle assembly including an elongate needle with a proximal end, a distal end and a passageway therethrough. The assembly has a needle hub with a proximal end, a distal end and an outside surface. The proximal end of the needle is fitted and held in an axial opening through the needle hub at the distal end of the needle hub, with the distal end of the needle projecting distally axially. The proximal end of the needle hub is configured for releasable mounting the needle hub on a fluid handling device. The assembly of the invention has a shield with an open proximal end, a distal end, a sidewall having an elongate opening extending from the proximal end to the open end. The shield is operative between an open position, where the needle is exposed for use by passage through the elongate opening, a closed position, where the shield substantially obstructs access to the needle, and a latched position, where the shield is substantially prevented from inadvertent movement to the open position. The shield is attached to the needle hub by a mount with a hinge. The shield is movable between the open position and the closed position by an off axis pivotal movement about the hinge, and between the closed position and the latched position by an axial movement of the shield with respect to the mount.

Title: Baffle assembly for a seed metering mechanism
Inventor: STUFFLEBEAM JOHN F
IPC: A01C7/10
Filed: 1997-08-19
Granted: 2002-07-16
Abstract: A baffle assembly for a seed metering mechanism that is mounted in combination with a seed hopper holding a supply of seeds that are to be dispensed into a furrow with regularity by the seed metering mechanism.  The seed metering mechanism includes a two-piece housing divided into a seed chamber and a vacuum chamber by a rotatable disc having a series of throughopenings or holes arranged circumferentially adjacent the perimeter of the disc.  The disc picks up seeds from the seed chamber and carries them around to a discharge area of the seed metering mechanism whereat they are released for gravitational deposit into the furrow in the ground below.  A seed delivery chute gravitationally directs the seeds from the seed hopper to an opening defined by the housing from which the seeds are deposited into the seed chamber. A salient feature of the present invention relates to the provision of a baffle assembly for controlling from outside of the housing the amount of seeds passing through said opening and passing into the seed chamber while maintaining the housing in assembled relation.

Cleaning solution with accompanying contaminants is preferably withdrawn continuously from a preselected location, or locations, and directed through a conduit, such as (76). Monitoring of iron fines in the main tank (73) is schematically indicated at (77). A continuously-operable mechanical filtering structure (78) is preferably selected to provide for withdrawal of a portion of the capacity of main tank (73) at a controlled rate. Filtrate, from which iron fines and associated debris have been mechanically filtered, is continuously returned from mechanical filtering structure (78) through conduit (80) to main tank (73).

Abstract: An electrical connector is encapsulated with a uniform thickness of a transparent insulating material, preferably a clear PVC. The transparent insulating covering permits visual inspection of wires inserted into the connector before tightening the set screws to insure proper installation of the wire. Clarity of the insulating material over the entire connector is achieved by using the injection molding process, which also results in a uniform thickness of the insulating material over the body of the connector as well as cylindrical extensions for the wire and set screw openings.

Abstract: An omni-directional treadmill providing a surface with no gaps on which a user can move. The treadmill is generated by arranging a set of looped belts (1, 2, 10), each providing at least one elongated surface, abutting one another along the elongate edges provided by the elongate surface. A group of these elongate surfaces defines the treadmill surface. This set of belts (1, 2, 10) is itself arranged in a loop. Movement of the whole set of belts around this loop moves the treadmill surface in one direction. Simultaneous rotation of all the belts (1, 2, 10) providing the surface provides movement perpendicular to the first direction. Using these two components of motion the treadmill can move in any direction indefinetly. Feedback from user can be used to move the treadmill in the opposite direction to keep user in the same place, in the same way a treadmill maintains user moving in one direction in the same place.

Abstract: A method and apparatus for switching n data streams for input and output of the data streams by an n input, n output data store without data loss. The data store is divided into n separate storage arrays and each data stream is divided into n equal-sized pieces. Then, during each one of n separate time units, one data stream piece is written into a corresponding one of the storage arrays; or, one data stream piece is read from a corresponding one of the storage arrays. For each data stream, during each time unit i, where 1 ~ i ~ n, an i th data stream piece is written into an i th one of the storage arrays, or an i th piece is read from an i th storage array. During each j th time unit, where 1 ~ j ~ n, one data stream piece P ij is written into an i th storage array, or one piece P ij is read from an i th storage array. Before the writing or reading step, each data stream is shifted log2n separate stages, such that for each shifting stage each data stream is shifted by:   2(log2n)-1 bits in the first shifting stage; 2(log2n)-2 bits in the second shifting stage; ... ; and, 1 bit in the n th shifting stage.

The signal is monitored during at least portions of the treatment period to detect a physiological event for use in controlling therapy of the patient during the treatment period. Energy consumption by the sensing device is terminated during the treatment period for at least portions of the treatmen t period when signal monitoring is not performed. Another method for operating  an implantable therapy system for conserving energy includes providing an implantable component for performance of a function during a treatment perio d for the therapy system. The implantable component is operable in at least a first state during the treatment period and a second state outside of the treatment period; the first state using more energy than the second state. T he implantable component is operated in the first state when performance of the  function during a treatment period is required and operated in the second state when performance of the function is not required outside the treatment  period. Another method of operating an implantable therapy system includes monitoring a periodic physiological parameter for controlling therapy of a patient during a treatment period. The measured physiological period for the  parameter of the patient is compared to at least one predetermined period threshold to determine nonperiodic behavior of the monitored periodic physiological parameter and suspending therapy of the patient as a function thereof.
