Title: Shear displacement depth of field
Inventor: COOK ROBERT
IPC: G06T15/10
Filed: 2008-05-23
Abstract: Depth of field effects for computer generated images are generated by assigning lens positions to image sample points. For each image sample point, scene geometry shears towards the center of the sample point's aperture to account for its assigned lens positions. The sheared scene geometry is sampled from a single point of the aperture, such as the aperture center image samples with different assigned lens positions sample different sheared versions of the scene, producing a depth of field effect. Scene geometry is sheared according to a function of its depth and the image sample point's assigned lens position. The depth of field effect can be characterized by any arbitrary function of depth, including static or varying aperture size and focal length, which allows for depth of field effects not possible with typical real-world optical systems image sample points, lens positions specified in a pseudo-random and/or stratified manner.

Title: Electrical resistors
Inventor: BASSETT JOSEPH ALFRED
IPC: H01B1/24
Filed: 1958-03-28
Abstract: 852,934. Voltage dependent resistors. MORGAN CRUCIBLE CO. Ltd. March 25, 1959 [March 28, 1958], No. 10116/58. Class 37 A voltage dependent resistor is made by bonding together two conductive members by means of an insulating adhesive containing particles of silicon carbide. In one embodiment a strip of adhesive tape sprinkled with finely divided silicon carbide is applied to a brass disc coated with an epoxy resin, e.g. "Araldite" (Registered Trade Mark) and the assembly heated under pressure to cure the resin and to embed the particles therein. After stripping off the tape the resin coated face of a similar disc is pressed against the coated face of the first disc and heated at 150‹C. for half an hour to set the resin, any surplus being subsequently removed from the edges of the discs. The first discs of several such elements may be made simultaneously by application of a number of resin coated discs to a long strip of the adhesive tape. In an alternative method silicon carbide particles are applied directly to a disc coated with insulating adhesive or the particles are mixed into the adhesive prior to its application to the disc. Another coated or uncoated disc is then pressed against the coating and the assembly baked to cure the resin. The ultimate spacing of the discs is determined by the size of the silicon carbide particles which under pressure are formed into a single particle layer.

Title: Reference signal servo system
IPC: G05D3/14
Filed: 1969-02-26
Abstract: 1,200,584. Automatic speed control. AMPEX CORP. Feb.26, 1969 [March 1, 1968], No.10225/69. Heading G3R. In a system for controlling a driven member according to a reference signal indicative of the desired condition of the member a secondary control loop is provided to remove unwanted variations in the reference signal. In a system for controlling the speed of the head drum 3 of a video tape recorder, the reference signal 59 is derived from the sync. pulses in the video signal during recording and from a control track of the tape during playback. Irregularities in the reference signal are removed by the secondary control 17 and the resulting reference signal is compared with the output of a tachometer generator 21 in a bi-stable circuit 19, the output of the comparator 19 after intergration controlling the energization of a printed circuit motor 9 driving the drum 3 so that the drum is synchronized with the reference signal. The control 17 includes a variable frequency oscilator 37 supplying the reference signal to the comparator 19. The frequency of the oscilator is set by a voltage normally derived from a pre-set 43 but modified by the output of a comparator 29 whenever the oscilator output differs in phase or frequency from the incoming reference signal 59 so that the reference signal applied to comparator 19 follows the incoming reference in frequency and phase. Since however the feedback loop 17 is relatively slowacting irregularities are removed. If the incoming reference signal disappears, e.g. when the rotating head 5 leaves the tape 7, a clamp circuit 33 suppresses the output of comparator 29 so that oscilator 37 stays at the pre-set frequency. The circuitry of the control 17 is described Fig.3 (not shown) employing transistors.
