Abstract: A system for conditionally redeeming an electronic coupon includes a distribution module distributing the adaptive electronic coupon (14) to a user. Electronic coupon metadata automatically changes redemption characteristics of the coupon based on predetermined conditions relating to personal data (24) of the user and a redemption environment (26). A redemption system honors the adaptive electronic coupon at a time and place of redemption based on the predetermined conditions relating to the personal data (24) of the user and the redemption environment (26).

Abstract: A low level video auxiliary signal is transmitted in addition to the conventional composite black and white or color television signal. The auxiliary signal is in the form of redundant, opposite-polarity signal portions during pairs of time successive signal portions, such as horizontal lines or fields of the composite television signal. The auxiliary signal also may be transmitted in the form of a predetermined frequency with the auxiliary information on successive lines of the composite television signal being out of phase by one-half the period of the auxiliary signal frequency. When the composite signal is detected and displayed by the conventional circuitry in the receiver, the auxiliary information is visually cancelled in the image displayed on the cathode ray tube and the normal video information is displayed.

Abstract: A turret indicator for a television receiver includes a stationary gear attached to a mounting base with a shaft passing through it. A rotatable carrier turret is mounted on the shaft and it carries five rotatable planetary indicator turrets which are programmed with channel numbers, five on each indicator turret to give a total of 25 indicating positions. When the rotatable carrier turret is rotated, the numerals on the indicator turrets appear sequentially at a viewing window in the television receiver cabinet.
Abstract: A potentiometer assembly particularly suited for supplying tuning voltages for all of the bands of signals capable of receipt by a television receiver or the like, includes three segments of resistive material arranged in a circle on a support member. Each of the segments corresponds to a different band of frequencies to which the television receiver may be tuned. Band selection is effected by comparable conductive segments on the support member.In one embodiment, a single wiper is used to sweep all of the resistive segments to supply the desired tuning voltage output. A cam arrangement is used to adjust the detented position of the wiper relative to the support member to effect fine tuning at each position. Other embodiments utilize individually adjustable wipers for each station or detent position of the tuner, with each wiper being preset to effect the fine tuning at the detented position of the potentiometer assembly.
