| 20100108590 | FLUID FILTER WITH AN ATTACHMENT STRUCTURE ON AN ENDPLATE OF THE FILTERING ELEMENT - A fluid filter includes a filter element having a filtering media disposed between two endplates. One endplate includes an open flow passage that allows a working fluid to flow into or out of the media during operation. The other endplate includes a connection structure. A cover houses the filter element, and has an opening that is an inlet or outlet in fluid communication with the opening of the one endplate. The cover includes another fill opening proximate the other endplate. A cap is connected to the connection structure of the other endplate to close the opening of the cover. The cover is retained between the cap and other endplate. Generally, the attachment configuration between the cap and the other endplate of the filter element helps ensure that the filter element with the correct micron rating is installed in a filtration system. | 05-06-2010 |
| 20100213115 | NO FILTER NO RUN FLUID FILTRATION SYSTEMS - Improvements to “no filter, no run” fluid filtration systems are described. In one example, a filter includes a movable pin cage that has a first pre-installation position adjacent the bottom end plate and is temporarily connected thereto by a snap connection system, and a second position adjacent the upper end plate where it performs a valve interaction function. In another example, a filter includes non-centered valve pins that are rotatable relative to an upper end plate of the filter. | 08-26-2010 |

| 20080211683 | METHOD AND APPARATUS FOR LOOSE WIRING MONITOR - A system is provided in which the voltage phases, neutral, and ground are monitored and an alarm is generated if specific trigger conditions are met. These conditions are indicative of a possible loose neutral, loose wiring, or general over/under voltage condition. Specific algorithms can be used to determine the possibility of a loose wiring condition, and if limits are met, various alarm modes are started. | 09-04-2008 |
| 20080217108 | METHOD AND APPARATUS FOR A DRIVE-THRU PRODUCT DELIVERY VERIFIER - A system for improving the efficiency of drive-through delivery systems is provided. The system can provide complete error tracking and feedback; however, partial or no error tracking and/or feedback can be provided if desired. Errors in order fulfillment can be reduced. Detailed information on product weight and delivery timing can be provided. By analyzing the weight distributions of each food item or any other suitable measurements, production quality and consistency may be monitored. By analyzing the delivery times for each food item type or any other suitable measurements, production efficiency and restaurant work flow may be measured. | 09-11-2008 |
| 20090027061 | METHOD AND APPARATUS FOR AN ELECTRICAL CONDUCTOR MONITORING SYSTEM - A system and method for determining the status of each monitored conductor, and optionally indicating peak current or other parameters are provided. Wireless self-powered sensor elements can eliminate much of the wiring required in traditional systems, and greatly ease the installation in difficult underground locations. | 01-29-2009 |
| 20090027190 | METHOD AND APPARATUS FOR A LOW-POWER RADIO BROADCAST ALERT FOR MONITORING SYSTEMS - Methods and apparatuses for instrumentation to broadcast an alert or status condition which solves the problems of close proximity or a hard-wired connection are presented. One method uses a low-power radio broadcast transmitter to broadcast a message during an alert or status condition. | 01-29-2009 |
| 20110109320 | SYSTEM, METHOD, AND APPARATUS FOR A SAFE POWERLINE COMMUNICATIONS INSTRUMENTATION FRONT-END - A safe powerline communications instrumentation front end device including a voltage input for receiving a line voltage from a powerline, a voltage reducer for reducing the voltage of the line voltage, a filtering system for extracting a Power Line Communications (PLC) signal from the line voltage, and an analog output for outputting the PLC signal as an analog signal for communications test equipment. | 05-12-2011 |
