Patent CA-2184520-C (CA)
Inventor: MILLER VAN
IPC: A21C15/02
Filed: 1996-08-30
Granted: 2000-02-22
Abstract: Baked waffles, especially breakfast waffles, are brought to the market for commercial sale in unfrozen condition, being packaged in sealed aseptic packages. The waffles are prepared by being baked to an extent less than 100% and greater than about 80% baked, and at least until the temperature of the interior of the waffle being baked has reached at least 72°C. The waffles are removed from their waffle form and transferred to a packaging station while still hot, and are placed into heat stable package that is sealed while each baked waffle remains at an elevated temperature, thereby rendering the package aseptic. The sealed aseptic packages are cooled and stored so that the baked waffles arrive for commercial sale in unfrozen condition. The baked waffles, in their sealed aseptic packages, may have a shelf-life of up to three months. Conveniently, the baked waffles are prepared in an apparatus which comprises two chains of opposed waffle iron forms which pass through an oven for baking. The chain runs formed by a plurality of opposed waffle irons are positioned so that the waffle irons are closed and opened due to the geometry of the chain runs, whereby loading and unloading each respective waffle iron is easily effected. Generally, a heated discharge conveyor zone is located at the exit end of the oven so that the temperature of the baked waffles remains at an elevated temperature throughout the period of time following its baking and until it is placed into the packaging. This renders the package aseptic; and after sealing the aseptic package, it is taken for subsequent cooling and handling into the commercial market. Thus, the baked waffles are brought to the market unfrozen, in sealed aseptic packages.

Abstract: A printed circuit board test fixture includes a plurality of flexible printed circuits having circuit traces on one side for interconnecting the test probe pin assemblies of the fixture with the interface connector pins for the interface panel of the fixture. The flexible circuits are folded in the fixture housing to provide spaced apart non-contacting layers of first contact areas for connection to the test probe pin assemblies and spaced apart non-contacting layers of second contact areas for connection to the interface connector pins. The layers of flexible circuit of each contact area receive the test probe pin assemblies and interface connector pins which secure the layers of flexible circuit in the fixture. The test probe pin assemblies and the interface connector pins make electrical and mechanical engagement with terminal apertures in the layers of flexible circuit. The layers further include through holes allowing the test probe pin assemblies and interface connector pins to pass through layers of the flexible circuit without making electrical contact with these layers. This permits circuit traces to be used on each of the layers of flexible circuit for selected test probe pin assembly and interface connector pin connected pairs.

Abstract: An efficient, multichannel filter for CDMA modems permits multiple serial, digital bit streams to be filtered by digital signal processing techniques including sample weighting and summing functions. Each individual channel may have custom weighting coefficients or weighting coefficients common for all channels. If the weighting coefficients are by adaption, the same approach may be taken. The multichannel FIR filter is implemented with no multipliers and a reduction in the number of adders. To increase the speed of operation, the filter structure utilizes look-up tables storing the weighting coefficients.  The invention can be embodied either as a field programmable gate array or an application specific integrated circuit. The use of look-up tables saves significant chip resources.
