Abstract: An integrated backend and dynamic interface system can be provided for handling multiple transaction channels. In one example, a client device can receive a unique identification code corresponding to a guest at a physical location associated with an entity. The client device can forward the unique identification code to a backend system configured to analyze a history of the guest to determine a customized object previously obtained by the guest from the entity. The client device can receive information from the backend system about the customized object and configure a graphical user interface to indicate the customized object. The graphical user interface can also include a graphical option that is selectable by a user for adding the customized object to an object order for the guest.

Abstract: A precision key pad controlled controller for a resistance welding machine is provided which may be set to deliver welding power to each of a multiplicity of welding operations on a precisely controlled repeatable basis. The controller incorporates circuitry for assuring that an accurately controlled amount of power is delivered for each welding operation by providing precise phase angle control despite variations in line voltage and line disturbances. The controller is constructed to incorporate selected numbers of steps to be performed automatically in sequence by the controlled welding machine in carrying out a particular welding operation. The duration of each step of the welding machine, the amount of welding power to be delivered, and other parameters are set for each particular welding operation by the key pad, and displayed on an associated alphanumeric display.

Abstract: Method and apparatus for timing a plurality of participants or their vehicles to complete a designated course, and for automatically starting the participants at spaced time intervals derived in part from respective sample times taken by the immediately preceding participants to cover a selected portion of the course. Sensors at start, finish, and intermediate positions monitor the progress of each participant on the course; a crystal oscillator is selectively connected to a plurality of electronic counters to accumulate an elapsed time for each of a plurality of participants; and a digital display device displays the times of participants as they complete the course.

Abstract: In a method of keeping time by counting the cycles of an alternating current source and providing both alternating and direct current power from the alternating current source, the direct current power including a variable display voltage for illuminating the lights, displaying time using a plurality of lights and windows corresponding to the lights, generating signals from the alternating current source, counting and dividing the signals, decoding the counted and divided signals, and lighting the lights and windows in accordance with the decoding to display the time of day, and correcting, when necessary, the time displayed by the clock, the improvement comprising providing a plurality of electrical switches corresponding to the lights, the correcting being accomplished by actuating one of the switches, completing an electrical circuit upon such actuation of the switch and comparing the display voltage with the voltage applied to the light whose corresponding switch is actuated, the comparing being operative
