| 20090120605 | TUBE WALKER FOR EXAMINATION AND REPAIR OF STEAM GENERATORS - The present invention comprises an improved manipulator system having a remotely actuated tube walker assembly for reciprocally moving the manipulator along a tube bundle for inspection and repair of the tubes of the tube bundle wherein the tube walker has a movable inner section and an outboard section with both sections having groups of hydraulically actuated locking fingers which are selectively engageable with the tubes of the tube bundle so that when the fingers of the outboard section are locked the fingers of the inner section are disengaged and the inner portion can be moved axially to an aligned position with new tube locations. | 05-14-2009 |
| 20120125559 | TEMPERATURE CONTROLLER WITH TIME TO TARGET DISPLAY - A thermostat is described for controlling air temperature in a building. The time associated with causing the controlled air temperature to reach a target temperature is estimated and displayed to a user. Input from a user indicating the target temperature can be received and the estimating and displaying can be carried out in real time. The thermostat can be wall-mounted or the user input can be received and estimated time can be displayed using a remote device, for example that communicates wirelessly with other components of the HVAC system. | 05-24-2012 |
| 20130299122 | TUBESHEET WALKER FOR HEAT EXCHANGER INSPECTIONS - A robotic tubesheet walker having two rails connected by a central hinge, wherein the central hinge can be opened or closed by an actuation device. Upon each rail is mounted a carriage, wherein each carriage can move along its respective rail toward or away from the central hinge by means of a drive mechanism. Each carriage further contains at least two “gripper” attachment mechanisms, such as camlocks, to grip the tubesheet. The grippers either insert into tube holes within the tubesheet to fasten the respective carriage to the tubesheet, or retract to disengage. Further attached to the central hinge is a tool support fixture, and attached to the tool support fixture is a coupler that holds maintenance or inspection tools. | 11-14-2013 |
| 20140262134 | HVAC SYSTEM REMOTE MONITORING AND DIAGNOSIS - An apparatus for monitoring a heating, ventilation, or air conditioning (HVAC) system includes an indoor unit monitor module electrically connected to a current sensor and first and second refrigerant temperature sensors. The current sensor generates a first current signal based on aggregate current consumed by components of an indoor unit of the HVAC system. The refrigerant temperature sensors generate first and second refrigerant temperature signals, respectively, based on measured temperatures of refrigerant circulating within the HVAC system. The indoor unit monitor module receives, from a secondary monitoring module, a second current signal based on aggregate current consumed by components of an outdoor unit of the HVAC system. The indoor unit monitor module transmits data to a remote server to assess whether a failure has occurred or is likely to occur in the components of the HVAC system. The data is based on the current signals and the refrigerant temperature signals. | 09-18-2014 |
| 20140332178 | METHOD AND APPARATUS FOR DELIVERING A TOOL TO THE INTERIOR OF A HEAT EXCHANGE TUBE - A delivery system for remotely driving an eddy current probe through the tubing of a heat exchanger. The system uses a flexible shaft and air pressure to move an inspection probe through the heat exchanger tubes. The flexible shaft initially drives the probe through a sealed conduit to deliver the probe to the tube end at which point a seal on the shaft near the probe head contacts the tube inner surface allowing a buildup of air pressure behind the seal, thus driving the probe through the tube. | 11-13-2014 |
| 20150114595 | SYSTEM AND METHOD OF AUTOMATIC DETECTION AND IDENTIFICATION OF SYSTEM COMPONENTS - A system and method to automatically detect and identify system components, wherein the system includes a processing device and at least one system component operably coupled to the processing device via a discrete connection. The method including the steps of operating the processing device to detect at least one electrical characteristic of the at least one system component, and operating the processing device to identify a type of the at least one system component based on the at least one electrical characteristic. The method further includes the step of operating the processing device to allow a user to confirm the identified type of the at least one system component. | 04-30-2015 |
| 20160040925 | Field Data Sensor And Method Of Remote Performance Monitoring - A system and method for determining and reporting refrigeration equipment operating metrics using only sensed interior air temperature is taught. By repeatedly sensing interior air temperature an average food temperature metric, a runtime metric, a compressor cycle metric, and a door opening count metric is determined and reported. | 02-11-2016 |
| 20160069579 | AIR-CONDITIONING SYSTEM AND CONTROLLER - The air-conditioning system includes: an opening/closing device opening and closing an openable portion in an opening of a building; an air-conditioning device performing air-conditioning inside the building by consuming energy for operation; a monitoring device monitoring environmental information regarding the inside and outside of the building; and a controller controlling the opening/closing device and the air-conditioning device based on the environmental information from the monitoring device, date and time information representing a current date and time, building information representing a location condition of the building, and draft information determined by parameters including an opening area and an opening shape in the openable portion. The controller opens the openable portion and stops the air-conditioning device when the outside is more favorable in air environment than the inside, and closes the openable portion and starts the air-conditioning device when the inside is more favorable in air environment than the outside. | 03-10-2016 |
| 20160082808 | DIRECTIONAL CLIMATE CONTROL SYSTEM WITH INFRARED TARGETING - A heating, ventilating, and air conditioning (HVAC) system has a steerable outlet for directing a stream of treated air into a passenger compartment of a vehicle. A thermographic imager is configured to capture thermographic images covering a fixed region within the passenger compartment in which an occupant is potentially located. The HVAC control circuit is configured to a) compress a thermographic image to a temperature map representing pixels of the thermographic image falling within a predetermined temperature range corresponding to the occupant, b) filter the temperature map according to a sliding window to coalesce continuous regions of pixels on average falling within the predetermined temperature range, c) quantify an area for each continuous region, d) locate a centroid of a continuous region having a largest area, and e) aim the steerable outlet toward the centroid. | 03-24-2016 |
| 20160096412 | PASSENGER CABIN INTERIOR ENVIRONMENT MONITORING SYSTEM - A system and method for monitoring environmental conditions in an interior portion of a vehicle. The system and method include a plurality of sensors that monitor environmental conditions in the interior portion of the vehicle and a controller that is programmed to receive sensor signals and compile indexes based on one or more of the sensor signals, built-in control logic and a history of user preferences. The controller is further programmed to determine if one or more predetermined threshold environmental conditions have been reached and to provide countermeasures when one or more of the predetermined thresholds has been reached. | 04-07-2016 |
| 20160116177 | DAMPER FAULT DETECTION - A damper controller may be configured to send damper control commands to open and close an outdoor air damper to provide free cooling as necessary to satisfy a temperature setpoint inside the building. In some cases, the damper controller may initiate a damper fault test to determine if a damper fault is present. The damper fault test may be based, at least in part, on an outdoor air temperature input, a discharge air temperature input, a commanded damper position, and a damper fault temperature threshold. If a damper fault is determined, the damper controller may send an alert indicative of a detected damper fault. In some cases, the damper fault test results may be weighted to reduce the false positives alerts. | 04-28-2016 |
