  • Platform independent file manipulation
    Patent number: 7200800
    Abstract: In an exemplary described implementation, an electronic device is configured to perform operations that include: activate a platform dependent module that is targeted to run on a current platform of the electronic device; activate an error detection module for the current platform using the platform dependent module; retrieve an error detection scheme; apply the retrieved error detection scheme to received data to determine error detection data; compare the determined error detection data to received error detection data; and if the determined error detection data matches the received error detection data, provide at least one feature with respect to the received data. Other apparatus, method, arrangement, system, media, etc. implementations are described herein.

  • Enclosed circuit interrupter including externally operable handle mechanism
    Patent number: 3978304
    Abstract: A molded case circuit breaker enclosed in a metal cabinet with an openable cover. An operating mechanism has a mounting plate secured to the face of the circuit breaker and a sliding plate movably supported on rollers by the mounting plate at the side of the circuit breaker. A handle mechanism is secured to the sliding plate with a portion extending through an aperture in the cabinet cover. A gasket is disposed between the handle mechanism and the interior of the cabinet cover. The handle mechanism is spring-loaded against the gasket and interior of the cabinet cover to provide a dust-tight seal.
