Abstract: This patent discloses various systems and embodiments for implementing, establishing and operating a remote order interface system and method. One exemplary embodiment of a remote order entry system includes a communications network, a first order entry workstation communicatively coupled to the communications network and configured to store a baseline commodity listing. The system further includes a second order entry workstation communicatively coupled to the first order entry workstation via the communication workstation and configured to communicate a remote commodity listing to the first order entry workstation, and a graphical user interface executable on the first order entry workstation and configured to display the baseline commodity listing in a first arrangement and the communicated remote commodity listing as a function of the first arrangement.

Abstract: A parallel RC network sensitive to the impedance of a gas discharge device is provided in the electronic ballast of this device along with a series connected inductive coil. As the impedance through the device changes, the oscillator frequency of the ballast would change accordingly and the voltage through the coil would change, thereby changing the impedance in such a manner as to insure that the voltage through the gas discharge device remains unchanged. The ballast would include a switch-mode, push-pull oscillator including a pair of emitter-resistors and a pair of fast diodes.

Abstract: The arrangement comprises a rigid structure having a support portion, e.g. in the form of a chair. On opposite sides of the support portion are hingedly mounted two step units. The step units are so designed and arranged that in their inoperative position they can be stowed under the support portion. When needed, one unit is pivoted through 90.degree. from under the support portion and comes to bear on the ground beside the rigid structure, and the other unit is pivoted through 270.degree. from under the support portion and comes to bear on the support portion. Each unit may have two steps and the two units may thus provide a flight of four steps. The rigid structure, when in the form of a chair, may have a back rest provided with a vertically slidable hand rest.
