    • Embodiments of the invention include a closure apparatus for clamping a transmission cable, such as an optical fiber transmission cable, and one or more tether cables. The closure apparatus includes a first member and a second member, each with a first partially cylindrical segment that fits around at least a portion of the transmission cable and at least one second partially cylindrical segment that fits around at least a portion of a corresponding tether cable. The first and second members are configured in such a manner that, when the first and second members are operably joined together, they form a closure around the transmission cable and the at least one tether cable in such a way that the transmission cable and the at least one tether cable are substantially parallel and co-planar with one another.

    • A dynamic focus amplifier for generating a dynamic focus voltage for a focus electrode for a cathode ray tube at a capacitive load includes a source of a periodic signal at a horizontal deflection frequency. A pull-down transistor is responsive to the periodic signal and coupled to the capacitive load for producing, in accordance with the periodic signal, a first portion of the dynamic focus voltage that decreases, during a first portion of a period of the periodic signal. A storage capacitor is coupled to the capacitive load for replenishing a charge stored in the storage capacitor from a charge stored in the capacitive load to develop a control voltage in the storage capacitor. A pull-up transistor is responsive to the control voltage and coupled to a source of a high voltage and to the capacitive load for producing from the high voltage a current that is coupled to the capacitive load. The current develops a second portion of the dynamic focus voltage that increases, during a second portion of the period of the periodic signal, and stores the charge in the capacitive load.
