A novel compound is having the structure, Formula (I): exhibits interesting odor characteristics, generally green in nature, particularly of a tomato leaf character, and so find use in perfumes and perfumed products.

The present disclosure is directed to a virtual pan/tilt camera system and method for use with vehicles, and particularly ground vehicles (MGVs). The disclosure utilizes autonomous navigation systems (ANSs) used with pan/tilt cameras, but eliminates the pan/tilt cameras substituting a plurality of video cameras. Each video camera is mounted in a fixed orientation on the vehicle and covers a selected angular range of lateral view. Commands from the ANS are mapped to selected addresses where the v...

This invention relates to the aromatic polyamide resin of the following general formula(I) having pendant silyl groups characterized in that the said polyamide resin has excellent solubility for the films to be easily prepared by solvent casting as well as useful as coating materials, can be used at higher temperature than the reported polyamides because of the excellent heat stability, and also has excellent adhesive strength in the blend with glass fiber. ##STR1##

A film correction system adjusts a relative position of film containing an area for information and a scanner of the film area. The system includes a scanner for scanning the film area at a film plane, A film drive moves the film along the film plane. A focused beam separate from the film area scanner scans a film edge in the film for determining a location of the film edge. A circuit is coupled to the focused beam scanner for changing a relative position of the film area scanner and the film ar...

A cable TV signal transmission system comprising a Nyquist filter carrier recovery circuit, a mixer, a level shifter and a pre-emphasis circuit for transmitting scrambled TV-IF signals on an FM or digital signal link to a receiver section comprising a de-emphasis circuit, an amplitude modulator circuit and a VSB filter so as to provide to remote TV receivers a scrambled TV-IF signal with correct timing between the video and audio scrambling information.

Described is pyridine derivatives defined according to one of generic formula (I) ##STR1## wherein R.sup.2 represents isopropenyl group when R.sup.1 is methyl or ethyl group, R.sup.2 represents isopropenyl or acetyl group when R.sup.1 is isopropenyl group, R.sup.2 represents methyl group when R.sup.1 is isopropyl group and R.sup.2 represents isopropenyl, or isopropyl group when R.sup.1 is acetyl group; and perfumery composition containing the derivatives.

A video data receiving apparatus displays the program video inserted the CM vide with the desired timing and the desired from based on the demand of viewers. Further, a video data transmitting apparatus transmits the CM data and the program data to display the program video being inserted the CM video with desired form on the receiving apparatus. Still further, a broadcasting system wherein the program video inserted the CM video with the form based on the demand of the viewer are displayed on t...

Video signals are encrypted so that only the privileged viewers can watch them. A layer coding unit divides video signals into two layers and encodes each layer. An encrypting unit encrypts the low-quality layer data items according to the setting signal from a secret level setting unit and supplies the encrypted signal to a combining unit. Another encrypting unit encrypts the high-quality layer data items according to the setting signal from a secret level setting unit and supplies the encrypte...

A broadcast signal receiver retrofit apparatus that receives broadcast signals, detects rating or category codes therein and compares the detected codes to a setting set in the retrofit device. If the comparison indicates that the incoming signal has a rating greater than that set or is of an undesired category the broadcast signal is blocked or an audio or visual alert is given. The retrofit device may be tamper-resistant to prevent disabling the device.

A digital data system that includes a control system at a customer site that blocks access to a down-loaded stored program after it has been viewed a predetermined number of times (e.g., once), or after a predetermined interval, or any combination thereof.
