Abstract: Described here are devices, systems, and methods for applying pulsed or modulated electric fields to tissue. In some variations, a device may comprise a first elongate body comprising a lumen, a second elongate body at least partially positioned within the lumen, and an expandable member rolled about the second elongate body. The expandable member may comprise an inner end coupled to the second elongate body, an outer end coupled to the first elongate body, and an electrode array.

Abstract: A quick release skewer assembly for use in mounting a wheel to wheel supporting fork includes a camming lever that is pivotally coupled to the skewer for pivoting relative to the skewer between lever closed and lever open positions. With the skewer properly tightened on the fork, pivoting the lever to the lever closed position clamps the wheel to the fork with a clamping force. A biasing member coupled to the skewer and to the fork applies a biasing force that biases the lever toward the lever open position. When the skewer is insufficiently tightened, the biasing force moves the lever to a bias rest position between the lever closed and open positions. The positioning of the lever in the bias rest position provides a visual alert to an individual using a vehicle, such as a bicycle, that the wheel is insufficiently tightened.

Abstract: The present invention relates generally to handle stops. More particularly, the invention encompasses a positive handle stop for a switch. The positive handle stop for a switch, such as, a safety switch, prevents the handle of a switch from returning to the shipping position once the switch is turned ON. The invention also includes a shipping position for the inventive handle so as to reduce the size of the packaging need to ship the switch apparatus.

Abstract: Hydrogen sulfide and mercaptans may be removed from a fluid or gaseous stream by reacting the hydrogen sulfide and mercaptans in the stream with a scavenger selected from a: (i.) 1,3,5-trisalkanylamino hexahydro-1,3,5-triazine derivative; (ii.) morpholine or piperazine derivative; (iii.) amine oxide; (iv.) alkanolamine; or (v.) aliphatic or aromatic polyamine.

Abstract: A system and method is provided for conveniently collecting woods chips or similar items. In one embodiment, a bag made from a lightweight mesh material and webbed portion is used as the liner of a wood chip truck, in which the bag collects the wood chips and can be easily removed from the truck when filled. A method of conducting a recycling business is also provided.

Abstract: A folding bicycle trailer includes a body portion having a passenger-receiving area, axle mounts, tongue mounts, and canopy mounts. The body portion is a unitary, one-piece monocoque structure, with the mounts being integrally formed therewith. An axle member is secured to the axle mount and carries wheel supports on each end thereof. The wheel supports are shiftable between an operable, extended position and a folded, storage position. A wheel is carried on each wheel support for free rotation relative thereto. An elongate tongue is carried on the tongue mount and extends forward from the body portion. A canopy frame, including fore and aft canopy members, is mounted on the body portion and is shiftable between a collapsible condition and a raised condition.

Abstract: A secondary control circuit including contrast control, brightness control, and a peaking circuit means are all disposed on a printed circuit board and coupled into the video circuit of a television receiver by one pair of connectors.
