Abstract: A video media clip synchronization tool has a timeline display which indicates, from its beginning, the running time of a video shooting event in hours, minutes and seconds. The tool also has two video frame displays which sequentially indicate frame numbers within a current second of the video shooting event. One of the video frame displays indicates the odd numbered frames within the current second of the video shooting event and the other of the video frame displays indicates the even numbered frames within the current second of the video shooting event. A single video frame number is displayed when the clips of video media and the video frame displays are synchronized. Adjacent odd and even video frame numbers are simultaneously displayed when the clips of video media and the video frame displays are not synchronized.

Abstract: There is disclosed a paging system for customers in a fast service or while-you-wait sales or service facility which is capable of being associated with or integrated with existing forms of point-of-sale hardware and software systems. The paging system notifies customers by means of an audio announcement or visual display, or both, that their order for service, identified by customer number, is ready to be delivered upon their return to the customer counter or to the delivery location. The system suppresses keyboard errors and permits correction thereof and provides for the display of several customer numbers on a continual basis until a respective customer number is deleted automatically or in response to manual input. Optionally, a skipped number feature makes service personnel aware of misdirection or unusual delay in fulfilling an order.

Abstract: There is disclosed a system and method to call sequentially serviced customers from a large area, such as a retail store, back to a pick-up counter, keeping track of any customer's jobs that have been skipped and not paged after a predetermined time. For example, in a pharmacy a customer is given a number when presenting a prescription to be filled. When the prescription is ready the customer's number is entered and shown on a large display in the center of the store to page the customer. If a number is skipped then this system solves the problem by showing the pharmacist skipped numbers on a screen of a keypad after a preset wait period and advises the pharmacist to determine why the customer was skipped. The system has an algorithm for detecting erroneous entries and recovery if a wrong number is accidentally entered.

Abstract: A novel way of powering a remote visual display and allowing data interchanges over the same wire pair. Such a station may be used for displaying the time, paging a person or an advertising message. The wire pair that powers a remote visual display also carries the electrically encoded message signal. On the same wire pair there is provision for the master message input station to exchange data with slave message input stations without message collision. Information from an input station key pad is captured by the microprocessor which converts the message to a serial binary signal. This signal drives a power transistor which converts a full wave rectified a.c. power current to a pulse width modulated signal which drives the wire pair connected to a remote visual display. The remote visual display power supply rectifies these signal pulses for power to drive the control circuits and display mechanism (light sources or light reflectors) and decodes the pulse width for display message information.

Abstract: The magnitude of a DC high voltage supplied to an internal element of a CRT is varied by a thermionic valve that is located within the envelope of the CRT and that forms a voltage divider with an external load resistor. Only a small scale signal referenced near ground is needed to produce a several thousand volt change in the high voltage supplied to the internal CRT element. The variable high voltage may control a variable deflection factor, variable spot size, or in the case of a beam penetration CRT, either variable persistence or variable trace color. In a particular beam penetration color CRT having a split anode the thermionic valve comprises a tetrode flood gun coupled by an electron mirror to a plate region in the neck of the CRT.
