Abstract: A system for automatically increasing a capacity of a virtual space in a virtual world may include a processor and a module operating on the processor for detecting an attempt by an avatar to enter a virtual space in a virtual world. The system may also include another module for determining if an allowable number of avatars is currently in the virtual space. The allowable number of avatars may be determined by at least a capacity of a server that is hosting the virtual space. Another module may be provided for increasing a capacity of the virtual space when the allowable number of avatars is currently in the virtual space. Increasing the capacity of the virtual space may include spawning a replicate new virtual space on a different server in response to the capacity of the server that is hosting the virtual space reaching the allowable number of avatars.

Abstract: According to some embodiments, a system and method for dispensing a floor coating in a specified ratio of multiple components is disclosed. The system and method may set and maintain a desired ratio of the multiple components by controlling, with a controller, a drive rate of respective pumps configured for propelling the components from a reservoir to a mixer or a dispenser. The controller may be responsive to at least one of a measured actual drive rate, an environmental condition, an actual usage of each component, and an operational parameter of the system, for adjusting a drive rate of the respective pumps to compensate for discrepancies that may affect the ratio of the multiple components.

Abstract: System and method provide wireless distributed lighting control systems implementing a secure peer-to-peer, self-organizing and self-healing mesh network of actuators and system inputs. The system and method can be designed specifically for indoor and outdoor lighting where actuators include in-fixture, on-fixture and circuit control modules with ON/OFF and full range dimming capabilities, and system inputs include occupancy/vacancy sensors, daylight sensors and switches. A unique messaging protocol facilitates wireless and wired communication between actuators and system inputs, and provides web-based commissioning and monitoring of the lighting control system using a wireless access point accessible from a local network or Internet which can provide an intuitive and easy to use Graphical User Interface (GUI).

Abstract: An air curtain arrangement and method of operating the arrangement are provided. The arrangement includes at least one air curtain unit having a supply plenum, a return air duct, and an intermediate air duct therebetween and separates relatively warm and cold areas. The air curtain discharges an air stream across a doorway from an outlet aperture of a discharge plenum toward an air return duct, at a discharge angle. A portion of the air stream is received at an inlet aperture of the return air duct. The portion of the air stream that is received at the air return duct is monitored. The discharge angle is adjusted to maximize the portion of the air that is received. One embodiment controls the discharge angle based on the temperature of the received portion of the air stream. Another embodiment senses the force of the air stream received proximate the inlet aperture.

Abstract: A stationary working surface of a one roll microcreper member is of plastic resin having low wear and friction properties. As a primary pressing member subject to concentrated force it is 0.040 inch thick. One or both opposed retarder members of a bladed microcreper are of the plastic. Thermoplastics meeting wear and friction limits, e.g. ultra high density polyethylene, are employed. Primary member extensions, some having openings, slots or holes serve as flexible retarders to engage treated material. Parallel slots, preferably formed by water jet cutting, defining machine-direction fingers provide particular advantages, often greatest when the fingers begin upstream of the creping cavity, and stated dimensional limits observed. By a load-spreading surface, the thermoplastic primary member is restrained without distortion. A primary member shown is sheet form, mounted between sheet metal members, one with a restraint surface. Sheet materials of polyolefins, wood pulp, etc.

By this surface being parallel to the roll axis the primary member is free for cross-machine thermal expansion.

Abstract: Wet wipe products are made from continuous wet wiping web material having thermoplastic fibers of type, concentration and dispersion capable of being heat-set to set the overall web material in a reformed shape. A succession of ridges and grooves is formed by passing the performed material through a dry creper apparatus in absence of adhesives, the action characterized by pressing the material with a stationary pressing surface to engage an advancing drive surface, the driven material bodily collapsing into a succession of adjacent ridges and grooves that increase the volume of the material. The wet wiping material is heat set in the ridge and groove configuration, enabling the ridge and groove configuration to be preserved when the wet wiping material is wetted and when squeezed and released. The self-restoring ridge and groove configuration provides stress concentrating edges and improves liquid delivery and wet wiping in a number of respects.

Abstract: A tamper resistant user interface device includes a substantially planar sensor. The sensor includes a plurality of user activated membrane switches. At least one multilayer structure is folded around and overlays the planar sensor. The structure includes at least one layer to detect tampering with the sensor.

Abstract: A conditioned vestibule for a cold storage doorway is disclosed. The vestibule includes a frame that supports inner and outer moveable door-forming members. The vestibule also includes a heater that circulates air between the inner and outer door-forming members and a variable-speed fan that varies flow of the air between the inner and outer door-forming members. In one embodiment, the airflow from the fan increases upon the opening of the door-forming members and decreases upon the closing of the door-forming members.
