Abstract: The motor has a rotor and a stator, a stator winding arrangement supplied with current from a D.C. source via a full bridge with an upper MOSFET connected to the positive supply line and a lower transistor connected to the negative line in each arm, and a commutating arrangement for the transistors. An arrangement alters the duty ratio of a PWM signal controlling the bridge depending on at least one motor parameter to reduce the current generated by the motor if the braking current exceeds a defined value.

Abstract: A method and apparatus for shading 3-dimensional computer generated images represents each object in the image as a set of polygons. An image plane on which the image is to be displayed is divided into a plurality of rectangular areas. Data defining the location of each polygon is then supplied. The rectangular areas which are required to show the whole of the polygon are then determined. Then, for each pixel in each rectangular area, the depth value is determined for the distance of a surface of the polygon from the image plane and a determination is made as to whether or not the surface is visible at that pixel. The pixel is shaded on dependence on the result of this determination.

Abstract: A junction field-effect transistor containing a semiconductor region with an inner region is described. In addition, a first and a second connecting region, respectively, are disposed within the semiconductor region.

Title: Modular containment and screening system
Inventor: JAMES E CULLINAN
IPC: E04H17/00
Filed: 2017-01-23
Abstract: A construction method and apparatus used to form a surround (8), container or other structure. Posts (10,12,14,16) have slots (50a, 50d) into which walls, which may be planks (20a-d, 22a-d and 24a-d) or made up of planks, are inserted and retained. Numerous posts (10,12,14,16) may be used with numerous walls there between to form many and varied structures. The finished structure is modular, because the posts (10,12,14,16) and walls are not damaged when the walls mount in the slots (50a, 50d). Therefore, if more or fewer posts (10,12,14,16) and/or walls are desired later, one need merely disassemble the structure and add the components desired to the existing structure. The walls may have fittings (60a, 60d) that attach to the inserted ends that cooperate with structures in the slots (50a, 50d) formed in the posts (10, 12, 14, 16) so the walls are held from being removed from the slots (50a, 50d) except along the length of the slots (50a, 50d). <Figure 1>

Title: VSS or Vessel Salvage System
Inventor: SCOTTO DI TELLA UMBERTO
IPC: B63C/
Filed: 1995-01-30
Granted: 1998-04-30
Abstract: The Vessel Salvage System ensures that any type of vessel will float under any weather and sea conditions. When a vessel sinks as a result of a defect or poor watertightness in the hull elements, the floats mounted on the sides of the vessel swell up and with their volume counterbalance the weight of the water taken on board and the on-board equipment. In the non-functioning (deflated) condition the floats are contained in longitudinal sections fixed to the outer part of the side. Control of the delivery of air can be manual or automatic, and in the latter case it ensures safety for vessels which are not manned. The control air itself can be used for automatically operating other safety devices/alarms such as radio or optical signals, etc. Manual command may deliver air to only the floats on one side, port or starboard, in order to provide a levelling torque for sailing vessels (prevention of capsizing). <IMAGE>
