Abstract: A portable exerciser that fits in a car that allows the user to exercise in traffic when the vehicle is not moving, or while the car is parked. The exerciser includes a body, resistance elements attached to the body and a tension adjuster, and handles attached to the resistance elements so that the user may exercise. The resistance elements are adjustable using the tension adjuster or replaceable for selecting the proper tension for any user. The exerciser is mounted behind or in front of the car seat, which can be the driver seat or the passenger seat.

Abstract: A cleaner head that includes an agitator and a drive assembly for driving the agitator. The drive assembly includes a dog for transmitting torque to the agitator. One of the dog and the agitator includes a shank having a screw thread, and the other of the dog and the agitator includes a bore having a complementary screw thread. The shank projects into the bore and the two threads mate such that, as the dog rotates, the agitator screws on to and tightens against the dog.

Abstract: A system may include one or more transmitter processing modules each having at least one of a plurality of modulation elements arranged in parallel. Each modulation element may be configured to modulate a respective baseband data signal at a different rate than other modulation elements. The system may include one or more receiver processing modules each having a plurality of demodulation elements arranged in parallel. Each demodulation element may be configured to demodulate a respective baseband data signal at a different rate than other demodulation elements. The system may include a first antenna for transmitting signals and a second antenna for receiving signals. One or more isolation systems may be used to actively cancel electromagnetic interference received by the receiving antenna from the transmitting antenna.

Abstract: In a method for removing dimethyl ester vapors or particles emitted from a molten dimethyl ester storage tank, a gaseous mixture containing dimethyl ester vapors or particles and an inert gas are supplied to an inlet port of a water scrubber. Water is continuously sprayed through downstream spray nozzles located inside the water scrubber whereby the water and air mix with the gaseous mixture to form a foamy mixture of dimethyl ester, air and water. Water through an upstream spray nozzle located inside the water scrubber is intermittently sprayed to wash an inner wall of an elongated body and the inlet port of the water scrubber to remove buildup of dimethyl ester particles. The foamy mixture is continuously removed from an outlet port. The water scrubber utilized in the method has an elongated body having an inner wall, a top with an orifice for receiving air, and a bottom with an outlet port. The inlet port is positioned on the body between the top and the bottom of the water scrubber.
