Inventor: MICHAL RUSSELL
IPC: G06F9/50
Filed: 2023-05-15
Abstract: A method for order independent transparency is described. The method includes rendering objects into an A-buffer by a GPU (102). A CPU (110) performs dynamic memory allocation to allocate the A-Buffer based on a size of the previous frames A-Buffer. By allocating the A-Buffer based on a previous frame, a GPU-to-CPU synch point may be removed. Depending upon a size of the A-Buffer, not all objects may fit into the A-Buffer. The method may additionally include creating an R-Buffer with the identification of partially stored objects and removing the partially stored objects from the A-Buffer prior to blending.

Abstract: A cable winding system carried by a vehicle for extending and retracting cable (14) responsive to vehicle movement. The cable (14) frictionally engages a controll- ably powered sheave (52) and is guided into a horizontally disposed coil by a cylindrical guide arm (22) having a vertically directed opening adjacent the sheave (52) and a downwardly, radially and circumferentially directed opening adjacent the coil. The guide arm (22) is freely rotatable about a vertical axis so that as cable (14) is extended and retracted the guide arm (22) rotates to guide the cable between the coil and sheave (52). The powered sheave (52) directs cable (14) from the vehicle through an instrumented fairlead (20) which, through a control system, controls the operation of the sheave (52). The fairlead (20) is pivotally mounted about a horizontal pivot axis (46) so that the head pivots in one direction as the cable is tensioned and in the opposite direction as the cable tension is relieved. The control system measures the angle of the fairlead (20) and may also measure the vehicle speed to cause the sheave (52) to extend cable (14) as the fairlead (20) moves rearwardly and / or the velocity of the forward vehicle is increased and to retract cable (14) as the fairlead (20) moves forwardly and / or the forward velocity of the vehicle is reduced. Also included is a failsafe system for applying the brakes of the vehicle when the supply of cable (14) in the coil falls to a predetermined value or when the fairlead (20) pivots to a point indicative of excessive cable tension and the rotational velocity of the powered sheave (52) is below a predetermined value.

Abstract: To portray movement in a television display, a field of the signal is stored in an image store (110), and subsequent input fields are compared in a motion detector (104) with the sorted field to detect differences between them due to movement. A flag is retained in an auxiliary store (114) to indicate the positions in the field of the detected differences. For those positions for which a new difference is detected, i.e. for which no difference has been detected previously, the corresponding portions of the then current input scan are stored in the image store (110), by a switch (106) being connected to the input (102). For portions which are flagged, the output of the auxiliary store (114) causes the switch (106) to take the output of the image store (110), thus insetting past positions of movement into the current field. The background of the field in the image store is nevertheless updated by the background of the input field. To allow for the 4-field NTSC or 8-field PAL cycle, transducers, or predictors, (170,160) are placed at the input and output of the image store (110) such that the image store retains information in one state only of the cycle. The motion detector (104) comprises a subtractor, a rectifier and a low- pass filter.

Abstract: A movable contact element is secured at the end of a thrust rod and therefore can be brought into and out of engagement with a fixed contact element. The free end of the movable contact element is surrounded by a blast nozzle which is likewise secured to the thrust rod. The inlet of the blast nozzle is operatively connected with a pump chamber containing an extinguishing gas and which can be pressurized during the course of a cut-off stroke of the gas-blast switch. This pump chamber is surrounded at its circumference by a cylinder which is displaceably guided upon a stationarily supported piston. To reduce the mass of the parts which are to be accelerated at the start of the cut-off stroke, the blast nozzle itself is constructed as a second piston situated opposite the first-mentioned piston and displaceable relative to the cylinder between two end positions. Means are provided in order to displace, during a cut-off stroke, the cylinder in the same direction or sense as the movable contact element, but however, through a smaller path than such movable contact element.
