摘要： A dual projection system utilizes a first projector and a second projector to project alternating left and right channel images of a 3D display. The projectors are inversely synchronized such that while the first projector projects a right channel image the other projector projects a left channel image. A projection filter in each projector has left channel properties when the image being projected is a left channel image and right channel properties when the image being projected is a right channel image. The images projected from each projector alternate between left and right channel images approximately once per frame.

摘要： Conductive polymer PTC compositions have improved properties, especially at voltages of 200 volts or more, if they are very highly cross-linked by means of irradiation, for example to a dosage of at least 50 Mrads, preferably at least 80 Mrads, e.g. 120 to 600 Mrads. The cross-linked compositions are particularly useful in circuit protection devices and layered heaters.

摘要： A light modulator configured to modulate at least two channels of an image to be projected and a lighting system configured to illuminate portions of the modulator corresponding to each channel with light having properties consistent with the channel. The channels comprise, for example, left and right channels of a 3D projection (e.g., a digital cinema projection). In one embodiment, the channels are provided by a multi-sectored filter wheel having at least one filter section for a first channel and at least one filter section for a second channel, where boundaries between the sectors are different in each section.

摘要： The resistivity/temperature characteristics of PTC conductive polymers which have little or no cross-linking can be modified by stretching. The rate at which resistivity rises with temperature is increased, and the peak resistivity is decreased; however, the decrease in peak resistivity is substantially smaller than that observed with PTC conductive polymers having a high degree of cross-linking. Therefore, heat-recoverable electrical devices, particularly for covering telephone and other cable splices, comprise (a) a layer of a PTC conductive polymer which has little or no cross-linking, (2) an adjacent heat-recoverable layer of a PTC or ZTC conductive polymer which has a relatively high level of cross-linking, and (3) electrodes which can be connected to a power supply so that current passes through the layers and causes recovery of the device; preferably an uncrosslinked PTC layer is sandwiched between two cross-linked ZTC layers. Non-recoverable devices, e.g. heaters, can have valuable characteristics when they comprise PTC conductive polymer elements which have been given a relatively low degree of orientation by stretching.

摘要： A motion picture soundtrack reproduction system has a center front soundtrack channel and a plurality of other soundtrack channels. A volume control adjusts the gain of all the channels. The volume control has a range of settings from a minimum to a maximum, the gain of the center front channel having substantially a first relationship to the volume control settings and the gain of the other channels having substantially a second relationship to the volume control settings, the relationships being such that for a range of volume control settings less than a first setting the gain of the center front channel remains substantially constant while the gain of the other channels decreases as the setting decreases or decreases more gradually than the gain of the other channels as the setting decreases.
