Abstract: In one example, a catalog service may use a peer-to-peer network to distribute a data content item across multiple associated user devices. The catalog service may maintain a device group list describing a device group and a content catalog for the device group listing a data content set stored in the device group. The catalog service may identify a content change to the data content set listed in the content catalog at a seed device of the device group. The catalog service may send an update alert to a leeching device of the device group of the content change to trigger the leeching device to receive the content change over a peer-to-peer network between the seed device and the leaching device.

Abstract: A dosing system including a dispensing tube to dispense a viscous liquid from a holding container to an output container, the tube includes an upper and a lower valve and a peristaltic pump to push against the dispensing tube and to cause the viscous liquid to open the lower valve.

Abstract: A home use carbonation machine includes a pronged clamp to fit a non-upright bottle to a flexible seal, thereby facilitating a closed carbonation environment in the bottle and a normally open safety valve to vent the bottle when the carbonation machine is not actively carbonating. A home use carbonation machine includes a carbonation assembly to carbonate liquid with pressurized gas, a pronged clamp and a centering ring with centering ribs to guide a non-upright bottle into the pronged clamp during insertion and to constrict prongs of the clamp when a user moves the non-upright bottle towards an upright position for operation.

Abstract: A novel and useful radio frequency (RF) front end module (FEM) circuit that provides high linearity and power efficiency and meets the requirements of modern wireless communication standards such as 802.11 WLAN, 3G and 4G cellular standards, Bluetooth, ZigBee, etc. The configuration of the FEM circuit permits the use of common, relatively low cost semiconductor fabrication techniques such as standard CMOS processes. The FEM circuit includes a power amplifier made up of one or more sub-amplifiers having high and low power circuits and whose outputs are combined to yield the total desired power gain. An integrated multi-tap transformer having primary and secondary windings arranged in a novel configuration provide efficient power combining and transfer to the antenna of the power generated by the individual sub-amplifiers.
