Title: Self-adjusting modulator
Inventor: DENT PAUL W
IPC: H03C3/08
Filed: 1994-06-06
Abstract: A self-adjusting quadrature modulator and modulation method improve the accuracy with which digital data is impressed on an RF carrier, which is particularly useful for systems having Viterbi, echo-integrating demodulatorsand for systems using subtractive CDMA techniques. The method and apparatus involve receiving one's own transmission with a suitable modulation assessment receiver and determining the modulation error relative to the theoretically perfect transmission expected by the receiver. The measured error is used to adjust the modulation to minimize the error. The modulation assessment receiver may use log-polar signal processing to measure phase and (log)amplitude instead of cartesian I and Q components, and then convert to cartesian form. In addition, correction factors determined by the modulation assessment receiver can be directly identified with certain transform components produced by the Fast WalshTransform.

Title: Method/process of bottling beverages
Inventor: ROSNAU LUCAS J W
IPC: B65D43/00
Filed: 1996-08-08
Abstract: Consumer food and beverages are not traditionally packaged with container closures that incorporate aromas. Container closures, e.g., threaded lids, press on/pry off caps, and the process of their application do not attempts to include aromas (i.e., fragrances, smells). This petition proposes a innovative, novel, and useful way to seal food and beverage containers (see "container" defined under Specifications). The idea is to intentionally add aromas to consumer food and beverage containers: the vicinity of a containers's mouth is scented and functions to stimulate a sensation -- physiological and 'psychological'. Patentable is the materials/process whereby those aromas are "added" to the container closure (i.e. patenting an improved process and its accompanying materials). The utility of this patent is its ability to expand consumer choices, diversify and improve producer's products, and to serve as an alternative to 'physically' flavoured food products. Traditionally aromas are added to either the food/beverage product itself or a void left in a container. In the instance of bottled water, this process means 'drinking' what you smell rather than 'eating' what you drink. The improvement suggested by the petition is distinguished by the fact that aromas are added to the bottling process (and accompanying materials) and not the food or beverage itself.

Patent CA-2190398-A1 (CA)
Title: Dog boot - neopaws
Inventor: SABEH ROANNA
IPC: A01K13/00
Filed: 1996-11-15
Abstract: A dog boot having as particular portions a sole, ankle and calf, the calf and ankle being large enough to accommodate the dog's paw passing through. The calf and ankle portions are generally composed of one piece of 3mm thick neoprene or some material with similar properties. The neoprene is sewn from the foot to the top of the ankle region, on the boot's frontal view. The front of the boot calf has a vertical opening whereby one side of the opening has a triangular extension such that it may wrap around said opening and adhere to the opposite side of the opening via a set of velcro patch means for fastening. This ability to connect the two sides so close to the front eliminates the need for a tounge and prevents slipage, key to maintaining the integrity of the fit. Said triangular extension is further extended by a horizontal strap or belt that continues in the same horizontal plane (set vertical place) as where said triangular extension fastens at one side of the boot; whereby said strap wraps around the boot, extending around its perimeter and fastening to an exterior velcro means for fastening adhesive patch found on the outside surface at the beginning of said strap. Said strap ensures that the first velcro connection does not come apart.     Said strap's exterior surface is covered with a reflective material. Said sole portion's exterior surface is composed of a textured, non-slip, rubber surface. Vulcanization connects said rubber surface to the exterior of the neoprene surface. The ankle, calf and triangular extension are made from a single cut-out of neoprene material. Other features add to the boot's advantages.
