20080221711METHODS AND APPARATUS FOR DETERMINING CHARACTERISTICS OF PARTICLES - An instrument for measuring the size distribution of a particle sample by counting and classifying particles into selected size ranges. The particle concentration is reduced to the level where the probability of measuring scattering from multiple particles at one time is reduced to an acceptable level. A light beam is focused or collimated through a sample cell, through which the particles flow. As each particle passes through the beam, it scatters, absorbs, and transmits different amounts of the light, depending upon the particle size. So both the decrease in the beam intensity, due to light removal by the particle, and increase of light, scattered by the particle, may be used to determine the particle size, to classify the particle and count it in a certain size range. If all of the particles pass through a single beam, then many small particles must be counted for each large one because typical distributions are uniform on a particle volume basis, and the number distribution is related to the volume distribution by the particle diameter cubed.09-11-2008

In one aspect, the invention includes a real-time sensor data communications bridge module; a state transition logic module; a sensor validation and predictive fault analysis module; and a statistical process control module; wherein each of the modules operates simultaneously.02-12-2009
20100204807Crowd optimization of ambient conditions - Methods and apparatus optimize ambient conditions of a physical location based upon input from multiple users (e.g., a “crowd) to avoid dominance by only one or a few users. Representatively, a plurality of input devices are distributed throughout the location and users, at certain times, or upon querying, enter their ambient condition preferences. Then, per the particular locations of the input devices, ambient conditions, such as lighting, temperature, sound, air flow, etc., are adjusted based on the inputs. In this manner, anyone can be in a room, at any time, and have their input considered as part of setting the room conditions. No longer does one or a few parties dominate control and no pre-programmed preferences are required. Controllers, input devices, systems, and computer program products, to name a few, are also contemplated.08-12-2010
20100049338Air conditioner system with optimizer - Described is an air conditioning system optimizer for optimizing operation of a compressor of the air conditioning system. The optimizer modifies a temperature and pressure of refrigeration fluid or gas operating for cooling purposes in the compressor and condenser coil within a compressor housing using enhanced water cooling by and with an exhaust air flow generated by a compressor housing fan. The optimizer includes a primary water cooling system that applies cooling water to the compressor through the compressor housing in a primary water cooling cycle and a secondary evaporative cooling system that operates with the primary water cooling system to capture once-used water in evaporative cooling elements and direct the once-used water to compressor housing locations susceptible to the exhaust air flow during normal air conditioning system operation in a secondary evaporative cooling cycle, controlling temperature and refrigeration fluid pressure to minimize compressor load in an energy-conserving and water-conserving manner.02-25-2010
20100010644SYSTEM AND METHOD FOR MANAGING APPLICATIONS - A system for managing a application includes a clock unit outputting time signals, a storage unit storing an age table, a detection unit and a resetting unit. The application includes a logical pointer and a flag carrying a flag bit. The age table includes ordered logical headers and age values, each logical header associated with an age value, the logical pointer pointing to one logical header, the age value having an increment as the logical pointer moves forward along the logical headers. The detection unit receives the time signals and reads the flag bit and moves the logical pointer to a succeeding logical header with a first step if the flag bit changes and with a second step if the flag bit remains unchanged during interval between two time signals. The second step is larger than the first step. The resetting unit resets the flag bit.01-14-2010

A building management system may analyze values observed by sensors and other devices and determine whether the observed values fall within a range. If the observed values do not fall within the range and the building's control system has not taken appropriate action to ensure that the observed values do fall within the range, the building may generate a floor plan specifying where the failure occurred. A building ranking system may rank a plurality of buildings based upon their relative efficiency. The building ranking system may determine each building's efficiency based on a set of parameters related to the building's energy usage that are normalized for weather, occupancy, and other external parameters.08-08-2013
