Abstract: A ventilation system for a space includes an air supply partition configured to cause filtered air to flow into an area of the space, and an air exhaust partition in spaced-apart relationship with the air supply partition and configured to cause air to be drawn in and filtered from the area. The air supply partition and the air exhaust partition create a “push-pull” air flow across the area. A ventilation partition includes air inlets in a first portion of the housing, air outlets in a second portion of the housing, a filter, and a fan configured to draw air in through the air inlets, through the filter, and out through the air outlets. The partition is a portable, free-standing structure configured to be supported by a surface, such as a floor of a room in which the partition is located.

Abstract: A fume hood adapted to be connected to an exhaust system has a ventilated chamber with a rear wall, opposite side walls, a ceiling, a floor, and an access opening. A baffle assembly is located in front of the rear wall and includes a lower panel and an upper panel. The lower panel has opposite side edges extending between the chamber side walls, a lower edge spaced apart from the chamber floor, and a plurality of air-exit apertures. The upper panel has opposite side edges extending between the chamber side walls, a lower edge attached to an upper portion of the lower panel, an opposite upper edge attached to the chamber ceiling, and a plurality of air-exit apertures. An elongated grating covers a gap between the lower panel lower edge and the chamber floor and includes a plurality of air-exit apertures.

Abstract: Fabric drop-down diffusers are disclosed. An example drop-down diffuser includes a first fabric sheet. The first fabric sheet is to extend away from a ceiling at a location adjacent a supply inlet. The supply inlet is to provide a flow of air toward the first fabric sheet. The example drop-down diffuser also includes a blanking sheet to restrict air flow through the first fabric sheet. The blanking sheet is to be disposed on an interior surface of the first fabric sheet. The blanking sheet has a lower permeability than the first fabric sheet.

Abstract: A fume hood adapted to be connected to an exhaust system has a ventilated chamber having an access opening, and at least one horizontally sliding sash or panel at the access opening that is configured to cover and uncover portions of the access opening. Each horizontally sliding panel has a peripheral edge that convexly curves into the chamber towards a centerline of the at least one horizontally sliding panel. In some embodiments, the peripheral edge is convexly curved in an arc of between about ninety degrees and about one hundred eighty degrees (90°-180°). The exhaust system creates air flow into the chamber and the curved peripheral edge produces controlled air flow patterns into the chamber. The curved edge is aerodynamically designed to help shed vortices and prevent accumulation of concentrations on the inside edge of the each panel typical of conventional fume hood sashes/panels.

Abstract: A computer system and method for managing commissions, including: a storage device containing a database having commission data and a periodic extract of sales transactions stored therein; a user interface for inputting the commission data into the database and viewing the commission data stored in the database; and a processor for calculating commissions for sales representatives and agents associated with a business enterprise based on the commission data, and forwarding the calculated commissions to a payroll department within the business enterprise; wherein the processor executes: a first software module for retrieving billing, inventory, corporate, and affiliated sales information for the sales representatives, and for calculating the commissions based on a predetermined rules set; and a second software module for retrieving billing and affiliated sales information for the agents, and for calculating the commissions based on the terms of a contract between the agent and the business enterprise.

Abstract: A system and method capture data from an SS7 network and pair each invoke message with its corresponding response message. Each message is stored in a daily file as well as in a table dedicated for that particular message type. A separate file is also maintained on each MIN and holds the most current registration information for each MIN. The system and method support four different types of queries: a MIN/ESN query, an active roamer query, a switch-to-switch query, and a transaction statistics query. The MIN/ESN query provides roaming activity on a specific MIN or ESN while the active roamer query provides information on all roamers in a serving market. The switch-to-switch query reveals messaging at one switch or between two switches. The statistics query provides data to a provider on all of its subscribers roaming in foreign networks or on all phones within its own network. The system has a Graphical User Interface (GUI) for displaying information on each message in an easy and convenient manner.

Abstract: A blade has a proximal end and a distal end and a central axis of elongation. The proximal end is generally rectangular cubic with a flat profile having top and bottom surfaces and short sidewalls, with each sidewall made up of two edges meeting to define an angle of approximately 95.degree. to 160.degree.. The apex of this angle is unsharpened and these sidewalls comprise guide means for guiding movements of the blade through an opening created by the cutting surfaces located on the distal end thereof The distal end of the blade includes a cutting surface made up of a sharp pointed tip with the cutting edges proximal of the tip defining an angle of 40.degree. to 140.degree. in one embodiment or 10.degree. to 60.degree. in another embodiment wherein these cutting edges further extend laterally and proximally to define an angle therebetween of 40.degree. to 140.degree. about a central axis of elongation. Two angled surfaces extend laterally and proximally to either side of the tip, each making an angle of 15.

Abstract: A blade has a proximal end and a distal end and a central axis of elongation. The proximal end is generally rectangular cubic with a flat profile having top and bottom surfaces and short sidewalls, with each sidewall made up of two edges meeting to define an angle of approximately 100.degree. to 140.degree.. The apex of this angle is unsharpened and these sidewalls comprise guide means for guiding movements of the blade through an opening created by the cutting surfaces located on the distal end thereof. The distal end of the blade includes a cutting surface made up of a sharp pointed tip with the cutting edges proximal of the tip defining an angle of 75.degree. to 85.degree.. Two angled surfaces extend laterally and proximally to either side of the tip, each making an angle of 22.degree. to 27.degree. with the bottom surface of the blade. The tip is located between the planes defined by the top and bottom surfaces of the blade. The inventive blade is made from diamond.

Abstract: Apparatus and methods are disclosed for providing wireless telecommunications service providers roamer visibility for on-line customer support and a fraud data feed for reducing losses due to fraud, obviating the need for each provider to purchase data from a central clearinghouse. Monitoring devices are coupled to existing network links (e.g., SS7 telecommunications links) or network elements (e.g., an STP pair), and are adapted to capture certain data regarding user traffic. The captured data is in turn provided via a wide area network or other transmission means to a message processor. The message processor collates raw messages received from the data capture devices and produces roamer visibility and fraud data. This subscriber-related data can be used to populate one or more databases available for query by on-line client workstations, or may, in the case of fraud-related data, be provided as a wire feed or other transmission to a fraud detection system or other wireless service providers.

Abstract: Charge on a floating gate of a semiconductor device structure is neutralized by illuminating the structure with a high intensity light during process steps that inject charge. The light provides for the formation of electrons, or free carriers, in the semiconductor substrate. The electrons facilitate tunneling which prevents dielectric degradation or rupture.
