20090101595 | Canister Filter System With Drain That Cooperates With Filter Element - A canister filter system includes a base, a canister attachable to the base, and positioned inside the canister a filter element having filter media. A drain engages and forms a seal with the filter element in a closed position. In an open position, the drain allows fluid to be removed from the canister. Because the drain is engaged to and forms a seal with the filter element in the closed position, the drain cannot be closed unless a filter element is present inside the canister. This prevents accidental or intentional use of the filter system without a filter element in place. | 04-23-2009 |

The fuel system may also have a manifold, and a valve movable to direct a first portion of a fuel flow discharged from the pump into the manifold and a remaining second portion of the fuel flow discharged from the pump into the conduit. The fuel system may additionally have a flow-disruption reducer disposed within the conduit between the filter and a discharge location of the remaining second portion of the fuel flow. | 11-28-2013 |
20130313183 | CANISTER FILTER SYSTEM WITH DRAIN THAT COOPERATES WITH FILTER ELEMENT - A filter element disclosed herein includes a center tube defining a central reservoir and including an interior sidewall. The filter element further includes an end plate and a pocket defining a port extending from the end plate into the central reservoir. The pocket includes an inner wall, an outer wall, and a plurality of projections extending from the outer wall of the pocket toward the interior sidewall of the center tube. | 11-28-2013 |
20140284266 | FILTER ASSEMBLY - A filter element includes a substantially cylindrical center tube having a first end, a second end opposite the first end, and a central longitudinal axis. The filter element also includes filter media extending circumferentially around and longitudinally along the center tube, and a plate connected to the center tube proximate the first end. The plate includes an orifice and a cap. The orifice includes a pilot feature configured to locate the filter element at a single circumferential position relative to the longitudinal axis, the cap extending from a top surface of the plate toward the second end and having an inner wall configured to mate with a drain plug. In such embodiments, the orifice and the cap are disposed radially inward of an inner circumference of the center tube, and at least one of the orifice and the cap extends circumferentially around an additional longitudinal axis spaced radially from the central longitudinal axis of the center tube. | 09-25-2014 |
20140366628 | VISUAL FLUID LEVEL INDICATOR - A fluid level indicator is provided for use with a fuel system. The fluid level indicator may have a generally hollow body with an open first end and a closed second end configured to be mounted at least partially inside a filter canister. The fluid level indicator may also have an annular float configured to receive and slide along the second end of the generally hollow body, and a plunger located within an interior of the generally hollow body. At least one of the annular float and the plunger is magnetic and configured to interact with the other of the annular float and the plunger. | 12-18-2014 |

20120062285 | DISCRETE TIME POLYPHASE MIXER - Embodiments of a radio frequency (RF) circuit provide translational filtering in accordance with an input impedance response that is an impedance image of a reactive circuit impedance response from a polyphase reactive circuit. The RF circuit may include a first mixer circuit that provides a first frequency offset for the impedance image and a second mixer circuit that provides an additional frequency offset. Accordingly, the second mixer circuit may allow for adjustments to a total frequency offset of the impedance image. The second mixer circuit may also be configured so that the impedance image rejects a negative frequency impedance response of the reactive circuit impedance response. | 03-15-2012 |

20130328605 | Non-Overlapping Clock Generator - A non-overlapping clock generator including an enabling module and N pulse-generating modules connected as a ring is provided. When the ith input node has a high voltage level, the enabling module enables the ith pulse-generating module so as to trigger the ith pulse-generating module to discharge the ith input node. After the ith input node has been discharged to a low voltage level, the ith pulse-generating module charges the ith output node to the high voltage level. | 12-12-2013 |
20140270021 | MULTIMODE RECEIVER WITH COMPLEX FILTER - One aspect of the present invention includes a radio frequency (RF) receiver having a first mixer and a second mixer. The first mixer may be an I-mixer and the second mixer a Q-mixer for downconverting the received RF signal. An impedance circuit is disposed between the first mixer and the second mixer to decouple the channels. In another aspect of present invention, the RF receiver includes a digital filter having at least one complex coefficient. The digital filter exhibits asymmetrical frequency response, and may be used to compensate the asymmetrical frequency response of another filter in the RF receiver. | 09-18-2014 |
