Abstract: A lever mountable to a handle bar of a vehicle, manipulated by at least one finger of a rider and having an arm with a distal end and a proximal end. The arm extends away from the handle bar, and the proximal end connects to the handle bar. At least one finger contour is located on the arm between the distal and proximal ends, and follows at least one finger to allow the at least one finger of the user to manipulate the arm. The lever also has a retainer located near at least one finger contour, and retains the fingers on the arm. The finger contour can contour at least two fingers. The retainer projects away from the arm and can be curved so as to secure the fingers to the arm. A handlebar of a vehicle having a lever as described is also claimed.

Abstract: A temperature stable bandpass folded filter for microwave radio communication, made from standard waveguide sections. Two waveguide sections are divided into cavities using metal plates made from a temperature stable material, to construct the filter. The sections are connected juxtaposed and the cavities of each section are coupled through holes in the coupled broadwalls of the section. Low insertion loss and very good temperature stability is obtained with the use of copper clad INVAR waveguide material. The method of constructing the temperature stable folded waveguide filter of reduced length is also disclosed.
