| 20090265373 | Method and Apparatus for Rapid Tagging of Elements in a Facet Tree - A tagging application (TA) is disclosed that comprises a web interface program (WIP) and a tagging program (TP). The WIP presents the facet tree by displaying elements of the facet tree selected by the user along with a known activation method for the user to select a facet element and to assign a value to the selected facet or facet element. The user may proceed to manually tag each facet and facet element by selecting a value representing the facet element to be tagged. The user may also eliminate manual selection of many of the facets and facet elements by choosing a tagging scenario and then applying the tagging scenario. Once the user has selected a tagging scenario, and has indicated that it is to be applied to the facet element, the TP takes the selected value and applies the selected tagging scenario to populate the tagging for the user in accordance with the tagging scenario. Once the tagging has been populated, the tagging program returns the tagged facet tree to the user at the user interface. Explanatory notes may be provided to the user along with the tagged tree. | 10-22-2009 |

| 20110227673 | GROUND STRUCTURES IN RESONATORS FOR PLANAR AND FOLDED DISTRIBUTED ELECTROMAGNETIC WAVE FILTERS - Coupling between non-adjacent resonators and wave propagation through the waveguide structure in distributed EM filters are reduced by forming one or more holes in one or more of the resonators (planar or folded) and by passing a conductive structure through each hole normal to the resonator. The conductive structures (vertical vias or horizontal strips) are preferably grounded, either by direct connection or capacitive coupling to one or more ground planes or by creation of a virtual ground. The holes are spaced apart from the edges of the resonator so as to minimize any interference with the current and fields concentrated at the edges of each resonator. These conductive structures narrow the effective cavity width “a | 09-22-2011 |

| 20090028656 | Force monitoring and control of router - An apparatus for force monitoring and control of a multi-axis router. The spindle assembly has a mounting plate that is attached to a base plate in the router assembly through three equally spaced load cells. The load cells are maintained in tension because the spindle assembly is suspended below the base plate. The center of gravity of the spindle assembly is in the center of the three load cells. Forces on the cutting tool are measured by the load cells, which are monitored by a controller that determines the load on the cutting tool. The feed rate of the cutting tool is adjusted based on the calculated cutting tool force. Abnormal conditions, such as an unbalanced or dull tool, are determined from the measured forces. | 01-29-2009 |

| 20080250798 | Method for sensing the liquid level in a compressor - Two vertically offset thermistors for sensing a fluid such as oil and refrigerant in a compressor shell are monitored by a method that takes into account rapidly changing conditions within the shell. The system can determine the fluid's sump temperature, high/low liquid levels, and can determine whether the thermistors are sensing the fluid as a liquid, gas, or a mixture of the two, such as a foam or mist of liquid and gas. For greater accuracy, thermistor readings can be dithered and filtered to provide temperature or voltage values having more significant digits than the readings originally processed through a limited-bit A/D converter. For faster response, limited microprocessor time is conserved by sampling thermistor readings at strategic periods that enable the microprocessor to identify certain conditions and temperatures via simple delta-temperature ratios and undemanding equations rather than resorting to exponential functions or lookup tables to determine time constants. | 10-16-2008 |
| 20080307810 | Operational limit to avoid liquid refrigerant carryover - A refrigerant system comprising a compressor, a condenser, an electronic expansion valve, and an evaporator is controlled in a normal operating mode to meet moderate cooling loads; however, when the load approaches that which is sufficient to induce liquid refrigerant carryover from the evaporator to the compressor, the system is controlled in a capped operating mode to limit a certain thermodynamic variable rather than controlled to meet the high load. In the normal mode, the compressor and/or the expansion valve might be controlled in response to the amount of superheat of the refrigerant leaving the evaporator or the level of liquid refrigerant in the evaporator. In the capped operating mode, the compressor and/or the expansion valve might be controlled to limit a variable such as the compressor's capacity, the saturated pressure or dynamic pressure of the refrigerant entering the compressor, or the refrigerant's mass flow rate. | 12-18-2008 |
| 20080309280 | Calibrating stepper motor by driving fractional ranges - A stepper motor driving a driven member is calibrated by periodically driving the member from its current operational position to an end stop of the driven member's total travel range; however, the driven member approaches the end stop in a series of ever-shorter travel segments. The first travel segment is less than ⅓ the total travel range to compensate for a possible sudden speed reversal, which can be accidentally triggered by the driven member reaching and “bouncing off” the end stop. Limiting the commanded first travel segment to less than ⅓ the total travel range prevents the driven member from reaching an opposite travel limit should the driven member suddenly reverse direction at three times the normal forward speed, wherein such triple speed is characteristic of reverse-speed situations. | 12-18-2008 |
| 20100121495 | Variable evaporator water flow compensation for leaving water temperature control - A method of controlling a refrigerant chiller system is particularly suited for chillers where the water being chilled (or some other liquid) flows through the chiller's evaporator at a flow rate that is variable and is not directly known. To effectively control the chiller and maintain the temperature of the water leaving the evaporator at a desired target temperature, the cooling capacity of the chiller's evaporator is estimated based the degree of valve opening of an expansion valve, a pressure differential across the expansion valve, and a change in enthalpy per unit mass of the refrigerant flowing through the evaporator. In some embodiments, the chiller system includes multiple refrigerant circuits that are hermetically isolated from each other. | 05-13-2010 |

| 20110309745 | LED Light Tube and Replacement Method - The LED light tube is adapted to replace a fluorescent light tube which is mounted in a fluorescent light tube fixture. These fixtures have first and second socket end mounts and each end mount mechanically accepts a bi-pin or other common connector for the fluorescent light tube. The fluorescent fixture is supplied with a main power line. In the present invention, the main power line may carry 110 to 277 volts. However, the present invention utilizes main power feed only to the first socket end mount of the fluorescent fixture and further maintains an open circuit between the main line power and the second socket end mount. The LED light tube includes an elongated tubular structure substantially the size and length of the fluorescent light tube and extends between the first and second end mounts of the fixture. Within an end region of the tubular structure and adjacent the first tube end mount, an internal power supply converts the main line power to LED bank power. The tubular structure of the LED light includes an elongated semi-spherical substantially transparent top cover mounted atop a printed circuit board substrate. The substrate supports a plurality of LEDs thereon. The transparent cover and the LED supporting substrate extends the length of the tubular structure other than the end region where the internal power supply is located. The tubular structure also includes an elongated hemispherical metal cover mounted below the printed circuit board substrate and beneath the plurality of LEDs as a heat sink for the LED replacement light. An electrical system within the tubular structure supplies the LED bank power to the plurality of LEDs on the substrate. The method of replacing the fluorescent light tube includes connecting the main line power to the first socket end mount in the fluorescent light fixture and opening an electric circuit between the main line power and the second socket end mount. The elongated tubular structure, having the size and length of the fluorescent light tube, has end caps complementary to the first and second end mounts and carries a plurality of LEDs therein. The tube has an elongated hemispherical transparent tube cover and the metal cover. An internal power supply converts the main line power to LED bank power and the method supplies the LED bank power to the LEDs on the substrate. The method also includes illuminating LEDs along the length of the elongated tubular structure except for the end region where the internal power supply is located. Heat is dissipated from the LEDs by the hollow space between the substrate and the metal cover as well as via the metal cover itself. The method includes electrically isolating the substrate from the metal cover. | 12-22-2011 |
