摘要： A record medium for use in the reproduction of picture information in the form of an elongated strip of recording material, such as photographic film, on which four sequences of mutually adjacent frames are disposed longitudinally in parallel relationship, each sequence representing a segment of picture information. Designating the lateral positions of the sequences across the film in ascending order from one to four, the frames of the first and third sequences are oriented for reading of their picture information with film motion in one longitudinal direction, and the frames of the second and fourth sequences are oriented for reproduction as the film is advanced in the opposite direction. In a preferred embodiment, the film contains two color programs, with one of the first and third sequences of frames containing monochrome representations of the luminance information of color pictures, and the other containing monochrome representations of the chrominance information of corresponding color pictures. Similarly, the second and fourth sequences of frames contain the luminance and chrominance information of a second color program. The film is packaged in a flip-over type cassette to facilitate playback of the film in either of the two longitudinal directions.

摘要： Apparatus and method for recording color picture information on a record medium, in which luminance information is recorded in one frame portion on the record medium and coded color information is recorded in a separate frame portion. Such luminance information may be in pictorial form and recorded either optically or electronically by a recording beam. The color information takes the form of a record including a first, carrier signal component modulated in amplitude and phase according to the color saturation and hue in the original scene and a superimposed reference carrier signal component bearing a fixed frequency relation to the color carrier signal, so that the recorded cycles of the respective carriers tend to be aligned in a common direction in the color frame. Recording may be carried out by scanning laser, electron or optical beam. as desired. The record medium may be reproduced by directing an image of a respective one of the frame portions to separate television cameras for producing a luminance signal and signals at the color and reference carrier frequencies.

摘要： An apparatus for monitoring the noise level of passing vehicles and for automatically photographing a vehicle which emits noise that exceeds a predetermined threshold level. The apparatus includes a vehicle sensor which acoustically determines when a passing vehicle reaches a chosen target area. In a preferred embodiment of the invention the vehicle sensor includes a pair of microphones and an acoustic delay line which feeds one of the microphones. The microphone outputs are correlated to determine when the vehicle enters the target area.

摘要： A synchronization pulse separator in an electronic system utilizes a clamp to remove synchronization pulses from a composite video signal. The signal, with the synchronization pulses removed, is then subtracted from a composite signal from which the pulses have not been removed. The subtraction is performed by a differential amplifier having a uniform pulsed output corresponding to the synchronization pulses.

摘要： Collimated coherent light is passed through a lens which establishes a cone of light converging towards a first focal point. A multifaceted reflector intercepts the converging cone of light and redirects it to a scanning focal point. At the point where it is intercepted by the reflector, the cone of light is large enough in cross section to illuminate simultaneously several facets of the reflector. The reflector may have generally the shape of a cone frustum and is rotated about its axis so that the scanning focal point scans an image surface. The first focal point is on the axis, and the scanning focal point therefore describes a circular arc. The image surface is curved to conform to the arc. The collimated light travels in a direction which may be parallel to the rotor axis but which is preferably inclined to the axis in order to provide improved optical efficiency.

摘要： In one embodiment of the invention described herein, synchronous blue and red color carrier correction signals of proper phase are developed from an encoded color television signal. The carrier signals have introduced therein fixed increments of correction to produce thereby blue and red black level correction signals. The signals are also supplied to a set of modulator circuits wherein the signals are modulated by decoded blue and red color component signals. The resulting gain control signals, which have amplitudes proportional to the instantaneous amplitudes of the decoded signals, are also corrected in increments. Furthermore, the signals are supplied to another set of modulator circuits wherein the signals are modulated by signals comprising the differences between gamma corrected and linear decoded blue and red color component signals. The resulting gamma correction signals have introduced therein fixed increments of correction and are thereafter combined with the color black level and gain control signals and added to the encoded color television signal.

摘要： Apparatus for simultaneously scanning two related frames of color TV film includes a disk rotated about its axis at high speed. Narrow radial slits in the disk cooperate with two separate fiber optics channels each formed with an entrance and a narrow exit. A lamp lights the disk, and the disk slits and exits are relatively oriented so that a scanning spot emanates from each exit and executes a rectilinear scan, notwithstanding curvilinear motion of the disk slits as the disk is rotated. Moreover, the fiber optics channels are tapered if necessary so that the scanning lines are of disk length, whether or not the disk slits are all at the same radial location.

摘要： A circumaural ear enclosure, including a rigid cup of reentrant shape and having a contour so as to be mounted within a protective helmet, for improving communication and safeguarding the hearing of personnel working in noisy environments. An air seal is obtained between the cup and the head of the user by a gel-filled cushion surrounding the ear, and attenuation of noise in a predetermined range of frequencies is maximized by dividing the cup into inner and outer cavities of unequal size with a partition on which the transducer is mounted and which includes means for providing frequency selective coupling between the cavities. This coupling is provided by a predominantly resistive element in parallel with a predominantly inertance element, these elements having values so as to assure maximum transducer response while maintaining high noise attenuation characteristics, with special emphasis to providing high noise attenuation at a particular frequency.
