The present invention relates generally to wireless transceivers, and more particularly but not exclusively to non 802.11 detection and avoidance methodologies for wireless devices including transceivers. In one or more implementations, a method for detecting non 802.11 operating in the unlicensed 5.25-5.35 and 5.47-10.725 GHz radio bands, using wireless devices, such as AP, are provided. An AP is used to automatically detect the presence of non 802.11 on all channels in these bands, alert all of its clients, and move to another channel that is known to be devoid of non 802.11 using one or more implementations.

A method for managing domain name acquisition comprises collecting desired domain names in a shared database and matching the desired domain names in the shared database to those that are available as candidates for a registration status change. A registration is then changed of at least one matched desired domain name due to the matched desired domain name being in the shared database. The registration of the at least one matched desired domain name may be changed to an entity who desired said matched domain name wherein the said entity is associated with the domain name being caused to be collected in the shared database. The collecting of the domain names in the shared database may comprise receiving a backorder of a domain name from an entity desiring said domain name and then storing said backorder of the domain name in a shared database. A domain name auction scheme is also provided to attain the highest price of a desired domain name that may be a candidate for deletion from a registry.

A system is equipped with a computer-controlled rotating gantry and includes at least one radiation source mounted to the gantry. The radiation source moves along an arcuate path as the gantry rotates and emits an x-ray beam at a first energy level for imaging of a small animal and emits an x-ray beam at a second energy level for radiation therapy of the small animal. The first energy level is less than the second energy level. The system's imaging capabilities are implemented with the use of a flat panel detector.

The invention provides a lipid of general formula (I) or (II): wherein X1, X2 and R1 to R5 are as defined herein. Such lipids are used to form complexes with a biologically-active material such as a nucleic acid, peptide or small molecule for delivering the biologically-active material to cells. The complexes may incorporate an integrin-binding peptide and, when the biologically-active material is DNA, thereby constitute a LID complex.

A pucker free garment seam providing a garment with a tailored and wrinkle free appearance. The pucker free seam and method for production utilizes a bonding strip which contains at least a thermal adhesive component which is inserted between first and second surfaces of a garment component along the seam. A sufficient amount of heat and pressure is applied to the seam which causes the adhesive of the bonding strip to flow onto the surfaces of the garment components thereby creating a compressed seam and permanently bonding the first and second surfaces of the garment component together along the seam to eliminate puckering associated with shrinkage of the sewing thread.

This bed comprises a front forwardly extending foot section having rearwardly extending side arms. Said side arms have similar, symmetrically disposed, horizontal offset portions raised above the horizontal plane of the bed mattress supporting fabric of the bed platform when the bed is in open sleeping position. In the closed position of the bed, the foot section projects rearwardly and said offset portions are then disposed below the horizontal plane of the mattress supporting fabric and hence in a depressed plane. The fabric is connected to each of a pair of zig-zag springs disposed alongside said depressed portions (in the closed position of the bed), at points disposed inwardly of the ends of the zig-zag springs, and also by a pair of helical tension springs to the side arms, at locations beyond the outer ends of said depressed portions. With such construction, persons sitting at the ends of the sofa (when the bed is closed) have a softer, more comfortable seat, because of the depressed side portions of the foot section and because of less tension on the fabric, and also more relaxing, softer seating between the ends of the sofa, because of use of less helicals to connect the fabric to the bed frame at the sides of said foot section. The ends of the zig-zag springs are furthermore received in the end helical springs on each side of the foot section to house and encase said ends.

Methods and apparatus to power an exercise machine are disclosed herein. An example method includes measuring a power supply current produced by a user of the exercise machine. A rotations per minute of the exercise machine is measured. A power supply reference current is determined, the power supply reference current based on a user selected wattage and the rotations per minute. A differential power supply current is calculated based on the power supply reference current and a measured current of a power supply of the exercise machine. A power supply duty cycle is calculated based on a previous power supply duty cycle, a time constant, the differential power supply current, and a previous differential power supply current, the power supply duty cycle to control power supplied to a console of the exercise machine. The power supply duty cycle is output to a power output controller.
