Title: Redundant serial bus and method for the operation thereof
Inventor: JANTZEN WOLFGANG
IPC: H04L12/26
Filed: 1998-06-11
Granted: 2003-10-07
Abstract: The invention relates to a redundant serial bus and a method for its operation. In order to connect serial bus systems which are known per se but have no system-integrated redundancy means to one another by means of bus lines (11, 12) of redundant design, a redundancy means (3) is proposed which can be connected upstream and is connected between the bus communications interface (200) of a bus subscriber (2) and the redundant bus lines (11, 12). In this case, during operation, transmission always takes place on all the bus lines (11, 12), and a fault-free bus line (11, 12) is selected at the receiving end.

Patent CA-2314769-C (CA)

IPC: F23L1/00
Filed: 2000-07-28
Granted: 2004-05-25
Abstract: An outside air intake hood for receiving combustion air for delivery to a direct vent, fuel-fired heating appliance such as a water heater has an opposing pair of side inlets positionable to face parallel to an outside wall upon which the hood is mounted, an outer side wall extending between the inlets, and an outlet passage with an entry portion facing and spaced inwardly apart from the outer side wall. A generally v-shaped baffle member is positioned within the hollow body of the hood, with an apex portion of the baffle member facing the entry portion of the outlet passage. When the wind is horizontally blowing generally parallel to the outside wall, a side wall of the baffle member deflects the wind-driven outside air entering one of the hood side inlets into the outlet passage in a manner converting momentum of the entering air into pressure in a manner preventing the creation of an undesirable vacuum at the hood outlet. A bypass passage disposed within the hood outwardly of the outlet passage entry portion communicates the two side outlets and prevents undesirable wind-created overpressurization of the outlet passage. Such bypass passage representatively extends through a gap between the baffle and the entry portion of the outlet passage and may also extend through the baffle itself.

Abstract: An improved electrosurgical instrument is disclosed and claims which includes a reusable electrode shaft (14), a disposable tip (16) and a novel, insulated coupling (18) for removably connecting the disposable tip to the electrode shaft. The present invention provides several advantages and features. The coupling provides ease in connecting the disposable tip to the reusable electrode shaft in an operating room environment. Once the tip is connected to the shaft, the coupling provides a rigid and secure connection between the tip and shaft, such that the coupled tip/shaft assembly feels to the surgeon like a single, unitary instrument. In addition, the coupling ensures a good electrical connection between the tip and the shaft prevents the tip from inadvertently or accidentally becoming separated from the reusable electrode shaft, and maintains the position of the tip relative to the shaft by preventing the tip from rotating relative to the holder.

Abstract: A system and method are provided for designing high-spread, high-distance interleavers for turbo-codes. The first approach is called high-spread random interleaving, and is based on a new and more effective definition of interleaver spread. The second approach is called dithered-diagonal interleaving. Both methods can be used to design interleavers of arbitrary length. The second approach can actually achieve the theoretical maximum spread for many specific block sizes, and at the same time include significant dither for the elimination of low-weight codewords. Both design methods are easy to implement and require very little processing. Also provided is a method for modifying any interleaver to improve the distance spectrum for a specific turbo-code. It is shown that, for a block size of only 512 data bits and for a code rate of 1/3, the flares in the packet error rate (PER) and bit error rate (BER) curves can be kept below 10 -8 and 10 -10, respectively.

When more that one wiper blade is provided, the respective heating elements preferably have lengths which correspond to the length of the respective wiper elements within which they are mounted. When the heating elements are of different length, a longest one of the heating elements preferably has a lower electrical resistance per unit length thereof than a shortest one of the heating elements. Total electrical resistances of the respective heating elements may thus be substantially equal.
