Patent number: 7137502Abstract: A mail tray singulator for controlling the handling, movement and sensing of mail trays or other mail items into a single file arrangement on a conveyor system for downstream processing. The mail tray singulator includes conveyor modules configured at preferably right angles with respect to one another. The modules are configured so that they can be readily adapted to preexisting conveyor systems with minimal reconfiguration. The system may use differing speed, height and belt friction conveyor belts between adjacent modules to achieve separation and enhance the effect of the right angle configuration between adjacent conveyor modules. Guard rails and side rail rollers may also be employed. Photoeyes, in conjunction with a programmable logic controller, allow the conveyors to be started/stopped based on pre-programmed scenarios.Type: GrantFiled: May 7, 2002Date of Patent: November 21, 2006Assignee: Lockheed Martin CorporationInventors: Patrick J.

Publication number: 20040024730Abstract: Inventory management of work-in-process (WIP) inventory within a processing facility is accomplished with a staged holding area in concert with control systems. Receiving of material into the staging area is tracked by scanning mechanisms such as Radio Frequency ID (RFID) or bar coding methods. Aggregation of material is recorded by cart sizing factors into the automatic control system. Carts are stored temporarily in locations arranged in a pre-determined grid fashion. The grid location information for a cart is made known to the automatic control system for reference or reporting to production supervisors. Down-stream processing can request staged inventory material from staging operators via overhead message boards or computer screens. Requests may be by particular types of material or by specific cart grid location. Manual entry or manual release of material is also accommodated including manual corrections of staged materials.Type: ApplicationFiled: August 2, 2002Publication date: February 5, 2004Inventors: Thomas M.

Patent number: 6613688Abstract: A model-based approach for generating an etch pattern to decrease topographical uniformity involves placing reverse dummy features (50, 52, 70) in a region of a semiconductor substrate (40, 60) according to the topography of the region and adjacent regions. The reverse dummy features are placed inconsistently over the semiconductor substrate (40, 60) because the need for reverse dummy features is inconsistent and varies from design to design. In one embodiment, the reverse dummy features (50, 52, 70) having varying widths are placed with varying spacing between them and are placed in different regions. The determination of location, size and spacing of the reverse dummy features (50, 52, 70) is determined based upon the uniformity effect over the entire semiconductor die and may be used in conjunction with the placement of printed dummy features.Type: GrantFiled: April 26, 2002Date of Patent: September 2, 2003Assignees: Motorola, Inc., Advanced Micro Devices, Inc.Inventors: Thomas M. Brown, Edward O. Travis, Jeffrey C. Haines

Patent number: 5708495Abstract: A method and apparatus for measuring the velocity of a gas flow that does not require the seeding of the flow is disclosed. The method and apparatus produce a population of stable molecules within the flow. This population of stable molecules is produced within the flow at a first time point. A population of excited molecules is produced from the stable molecules at a second time point by exciting the stable molecules with a laser beam. This laser beam also induces fluorescence in the population of excited chemical species at the second time point. Typically, the interval between the first and second time points is known and the velocity of the flow is calculated by dividing the distance travelled by the stable molecules in the flow by the known time interval. The preferred example of the stable molecule is ozone. Oxygen molecules are fluoresced by a 193 nm laser beam at a first time point, producing oxygen atoms.Type: GrantFiled: September 1, 1995Date of Patent: January 13, 1998Assignee: Vanderbilt UniversityInventors: Robert W.
