Abstract: A method of warming a toilet seat is described.  Firstly, provide a toilet having a toilet seat and a pivotally mounted toilet seat cover.  The toilet seat cover has a lower surface and a peripheral edge.   The toilet seat cover is pivotally movable between a substantially vertical raised position and a substantially horizontal lowered position in which the lower surface of the toilet seat cover overlies the toilet seat. Secondly, secure a string of low voltage lights to the lower surface of the toilet seat cover adjacent the peripheral edge. Thirdly, position the toilet seat cover in a pivotal position parallel to the toilet seat when the toilet seat is not in use. Heat generated by the low voltage lights in proximity to the toilet seat warms the toilet seat in preparation for use.

Abstract: An apparatus and method are providing for shredding and loading pre-portioned quantities of products, typically food products such as cheeses. The food product or the like is shredded at an on-line location which is a component of a filling and sealing line by which a plurality of pockets of packaging components are filled and then sealed under vacuum or gas-flushed conditions. The resulting pre-portioned shredded or grated product is moved into one of the pockets of the packaging component prior to the sealing operation. This movement is coordinated and in timed sequence with a conveyor assembly which properly positions the pocket under the fixture through which the grated product flows.      Tamping equipment can be provided by which the grated product is leveled off while it is within the pocket and prior to sealing. Multiple pocket filling is also addressed.

Abstract: A dockable equipment container includes an outer shell of a durable material and an inner metallic container. The inner container is suspended within the outer shell by blocks of energy absorbent material, such as a polyurethane elastomer. The dockable equipment container further includes a connector at one end, which is covered by a protective door. When mated with external equipment, the protective door is moved to an open position by an alignment device, such as alignment pins, pressing against an end of the protective door. The alignment pins mate with corresponding alignment holes for ensuring that the connector properly mates with a corresponding connector in the external equipment. The dockable equipment container may contain various electronic equipment, which communicates with the external equipment through the connector. The electronic equipment may include disk drives, which are protected from the environment and from shock by the construction of the dockable equipment container.

Abstract: A trigger sprayer apparatus is comprised of a sprayer housing and a vent housing that are formed independently of each other and are then assembled together. By providing a separate sprayer housing and vent housing, the sprayer apparatus may be produced in a manner that significantly reduces the occurrence of deformations or imperfections in the component parts of the apparatus. Molding the sprayer housing and vent housing separately enables the cylindrical interior surface of the pump chamber and the cylindrical interior surface of the vent chamber to be molded more accurately.      Because the sprayer and vent housings are molded separately, a lesser amount of material is needed to mold each of these components and therefore shrinkage of the material as the components cool is significantly reduces.      This eliminates the occurrence of deformations or sinks in critical areas of these component parts.

Abstract: A calibration network (110-130, 180, 182) for pro- viding weighting factors for a beam pattern of an adaptive array of antenna elements (86) of a communication device (70) is self calibrated by modulating and demodulating a narrowband channel with a common broadband signal con- taining a pseudo-random number sequence (PRNS) having a relatively short pulse rate per bit and a power level rel- atively low to that of a noise threshold of the narrowband signal channel. Errors introduced into the PRNS by a se- lected complementary one of a reception (116) and trans- mission (114) path are determined by calculating a process- ing gain for the calibration network based upon the errors introduced into the PRNS. Then, by applying a conver- gence algorithm (130) to resolve amplitude and phase vari- ations introduced by components (112-118) in the selected path, these amplitude and phase variations are mitigated against by the communication device (70) of the figure by subsequently determining and applying a correction factor (126) appropriate to compensate for these variations.

Abstract: A process for the thermo-hydraulic control of gas hydrates in subsea production and injection wells as well as pipelines which transport liquid or gaseous hydrocarbons is described, the process making use of a Nitrogen Generating System foamed or in solution. The control may signify the prevention of the formation of the gas hydrates or the dissolution of the gas hydrate plug already formed. Under conditions of use designed for the prevention of the formation of gas hydrates the SGN fluid prevents the thermal conditions leading to the gas hydrate plugs. Under conditions of use designed to dissolve the already formed gas hydrate plugs, the SGN fluid alters the thermo-hydraulic conditions which favor the gas hydrate plugs, so that they are dissolved and return to the water + gas phase.

Abstract: A call acceptance control method for a CDMA mobile radio communication system and a mobile station device which enable prevention of deterioration in radio communication quality of a communicating mobile station even under a dense traffic, sufficient suppression of the possibility of deteriorating the communication quality of a mobile station communicating with a peripheral base station, and improvement in efficiency without increasing a control signal traffic. A radio base station device measures the quantity of up-link interference and informs a mobile station of this quantity. The mobile station obtains the quantity of up-link interference informed of by the base station, and calculates a required receiving level at the base station anticipated in the case where the mobile station is accepted by the connected base station, on the basis of the obtained quantity of up-link interference. If it is judged that predetermined communication quality cannot be realized on the basis of the calculated required receiving level and the quantity of up-link interference, the call of the mobile station is determined to be unacceptable.

Abstract: Protection Bundles (PB) facilitate efficient protection switching in a network and can be applied at any network layer. A PB is preferably assigned to all working signals sharing the exact same protection facilities. The working facilities that a PB traverses define a Bundled Protection Fragment (BPF) (564, 568). The end-points of the BPF exchange coordination protocol messages along the protection facilities when necessary.
