Abstract: Carrier data can be communicated between a carrier interface of the first radio base station node and a mobile switching center over a carrier bus according to a carrier protocol. In addition, bus data can be communicated between a bus interface of the first radio base station node and a second radio base station node over a radio base station bus according to a radio base station protocol that is different from the carrier protocol. Related radio communications systems and nodes are also discussed.

Abstract: By providing a beard and mustache trimmer construction wherein a single motor driven element is employed for directly operating both the main cutting blades as well as a pop-up trimmer, an easily employed, efficient, beard and mustache trimmer is realized. The trimmer is constructed in a manner which enables the pop-up trimmer to be directly driven by the same element which drives the principal cutting blades. In this way, greater power is delivered to the pop-up trimmer element than has otherwise been attained with prior art systems as well as providing substantially reduced noise levels. As a result, a substantially enhanced cutting and trimming system is realized.

Abstract: By providing a rotatable wheel mounted in cooperating engagement with a longitudinally movable arm or slide member, an easily employed, dependable, and reliable movable comb control system is achieved, enabling users to controllably move the comb member on a hair trimmer any desired distance. In the present invention, cam slots are formed in the wheel with the slots positioned for controlled engagement with cam pins formed on the movable arm or slider. By employing this construction, rotational movement of the wheel causes controlled movement of the cam pins which results in the desired longitudinal movement of the arm/slider. By securing the elongated arm/slider to the comb element, either directly or through an interconnecting plate, the longitudinal movement of the arm/slider causes the comb element to move simultaneously therewith.
