ens Blind I/Q mismatch compensation with receiver non-linearity By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT Apparatus and methods disclosed herein perform gain, clipping, and phase compensation in the presence of I/Q mismatch in quadrature RF receivers. Gain and phase mismatch are exacerbated by differences in clipping between I & Q signals in low resolution ADCs. Signals in the stronger channel arm are clipped differentially more than weaker signals in the other channel arm. Embodiments herein perform clipping operations during iterations of gain mismatch calculations in order to balance clipping between the I and Q channel arms. Gain compensation coefficients are iteratively converged, clipping levels are established, and data flowing through the network is gain and clipping compensated. A compensation phase angle and phase compensation coefficients are then determined from gain and clipping compensated sample data. The resulting phase compensation coefficients are applied to the gain and clipping corrected receiver data to yield a gain, clipping, and phase compensated data stream. Full Article

ens Compensating mold plunger for integrated circuit manufacture By www.freepatentsonline.com Published On :: Tue, 05 May 2015 08:00:00 EDT A device and method for manufacturing integrated circuit packaging using a mold plunger with position compensation in a manufacturing setting. In an embodiment, a compensating mold plunger, which may be used during the manufacture of an integrated circuit package, engages a die set on a carrier and within a bushing. This may be done to inject a mold compound on top of the die/carrier. If the bushing that is housing the die/carrier tandem is misaligned with the plunger in any lateral direction, the amount of pressure may be compromised. A compensating mold plunger includes a flexible portion that allows for the head of the plunger to properly engage the die/carrier despite any possible misalignments. Further, different die/carrier combinations may also be used with a compensating mold plunger because the pressure and force applied may be uniform inside a bushing despite the contents of the bushing.

ens Method and apparatus for managing ammunition dispensing from a magazine using a flexible projectile control bar By www.freepatentsonline.com Published On :: Tue, 05 May 2015 08:00:00 EDT A double-magazine (“Dmag”) able to house projectile ammunition for a projectile launcher having a first ammunition channel, a second ammunition channel, and a flexible projectile control bar (“FPCB”) is disclosed. In one embodiment, the first ammunition channel contains a first set or column of projectiles and the second ammunition channel which is situated in parallel to the first ammunition channel is configured to house a second set of projectiles. Dmag also includes a follower with a follower lock capable of moving along the first ammunition channel. The follower is configured to push the first set of projectiles toward a first ammunition supply port of the first ammunition channel. The FPCB has a first flexible flap which keeps the first set of projectiles from reaching the loading port of the launcher until the follower lock is released. Full Article
ens Three dimensionally fiber-reinforced composite riser and methods of making the same By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT The present invention relates to a three dimensionally fiber-reinforced riser and to the unitary or single-step methods of making the same. In one embodiment (a cross bow riser for example), the riser has an interior support with opposed side members and a front brace. The front brace has a depression centrally located therein. Two side ribs are also provided for structural support. Two pockets each optionally having a divider wall defining a top and bottom section are provided for receiving respective top and bottom pieces of a split limb, when a split limb is used. The riser can be made of a composite material having fibers aligned there within in the directions of the highest stresses for enhancing the structural strength of the riser. Other bow parts or components can likewise be made via composite material as well. Full Article
ens Beer dispensing device and system By www.freepatentsonline.com Published On :: Tue, 12 May 2015 08:00:00 EDT The present invention provides an easy to use, convenient, compact, energy efficient, labor efficient, cost-effective, fast, safe, neat, electricity-independent, self-contained, portable beer dispensing device and system that uses CO2 or other acceptable gas to maintain the freshness of beer, presents a ready height and arrangement for dispensing chilled fresh beer, and can be used in a variety of professional, casual, indoor and/or outdoor settings. The present invention chills beer before it is dispensed but after it has been removed from the keg. The present invention incorporates use of a gas tank to propel beer from the keg, through the beer dispensing device and system so that the beer inside the keg will not go flat. The present invention offers a convenient arrangement of its components that simplifies its use, transport, set up, and break down. The present invention also provides a space efficient arrangement for dispensing chilled, draft beer. Full Article
ens Portable dispenser assembly By www.freepatentsonline.com Published On :: Tue, 12 May 2015 08:00:00 EDT A portable dispenser assembly for dispensing disinfectant to a user. The assembly includes a main housing defining a cavity for receiving a container in an inverted position. The main housing defines an opening into the cavity through which the container is inserted in the inverted position so that a stem of the container is directed downwardly in the main housing. The main housing including a bottom wall, a side wall, and a nozzle fixed with respect to the walls. The nozzle defines an inlet opposite the opening for receiving the stem of the container in the inverted position and the nozzle defines a discharge aperture configured to direct the disinfectant fluid from the container toward the user when the user depresses the container relative to the main housing to dispense the disinfectant fluid from the container.
