Abstract: Method and apparatus are disclosed for a system for keyless entry. An example vehicle includes a valet dongle, a dock configured to connect to the valet dongle; and a valet manager. The valet manager enables the valet dongle to authorize keyless entry and keyless ignition when (a) the valet dongle is removed from the dock while an ignition of the vehicle is on and (b) an authorized passcode is provided via an infotainment head unit.

Abstract: An explanation device operates to generate explanatory information for a user regarding the cause of any demands that could not be satisfied by an automated supply chain optimizer. The explanation device identifies the cause for any unsatisfied demands by successfully relaxing various supply chain constraints while controlling the supply chain optimizer to re-optimize the supply chain subject to the relaxed constraints. If a previously unsatisfied demand is satisfied during re-optimization by relaxing a given constraint, then that constraint is deemed to have been a factor in the original, unsatisfied demand. If so, explanatory information is output to the user regarding the constraint. The amount by which the constraint was originally violated during the initial optimization may also be determined and provided to the user as further explanatory information.

Abstract: Methods, systems and computer-implemented architectures are provided for performing supply chain planning. In one implementation, a system is provided that comprises a database configured to store master data descriptive of supply chain items, a model generator coupled to the database and configured to derive a master data-based core model representative of a supply chain planning problem, and a solver configured to translate the core model into a mathematical model and determine a solution to the mathematical model. In addition, the system may comprise a preprocessor configured to preprocess the core model by subjecting the core model to a set of rules to derive a preprocessed core model, wherein the solver establishes the mathematical model from the preprocessed core model.

Abstract: An automatic cost generation apparatus is provided for automatically converting user supplied definitions/requirements into cost parameters for use by a cost-based supply chain optimizer. In one example, this is achieved by generating a linear programming model that incorporates the requirements/definitions as a set of linear constraints. The linear programming model is automatically solved so as to yield a cost model, from which costs are extracted for use by the cost-based optimizer. By first formulating requirements/definitions as linear constraints within a linear programming model, the solution to the model therefore yields a cost model that satisfies the constraints, i.e. a cost model that satisfies the requirements. Hence, requirements/definitions initially provided by the user are thereby automatically converted into a cost model that incorporates costs that can be used during supply chain optimization.

Abstract: A skeleton ball comprising a plurality of loops woven together into a spheroidal grid derived from polyhedral geometry. The loops comprise elongated rod, strand or tube elements joined at the ends subsequent to the weaving process. Only one joint per loop element is required. The grid's connections are frictionally secured through mutual flexural deformation of loops as a result of the weaving process. The frictionally-secured connections allow some embodiments to be collapsed or folded flat through relative sliding motion of loops. Relative sliding motion of loops also allows enlargement of grid openings so the ball may be used as a tote or container. The ball may be designed for bouyancy without need for inflation. The ball is suitable as a swimming or aquatic exercise aid affixed to the limbs through relative sliding of loops.

Abstract: An improved, lightweight and removable leg walker is provided for stabilizing and rapidly healing lower leg injuries of a patient. The injured limb is disposed in a removable inner ankle bootie whose interior is partially covered with inflatable support bladders. While the foot is secured within the booties, it is then inserted into and additionally supported by a removable soft goods-type support. The soft goods-type support is securely attached to a walker frame by a combination of strap fasteners with Velcro attachments. Inflatable bladders are located along the inner surfaces of two strut bases and raised heel strip. A tongue portion of the soft goods-type support also includes an inflatable bladder which provides additional support to the injured limb. These inflatable bladders encourage proper circulation from the lower leg to the heart. The walker frame comprises a pair of strut bases and struts in order to prevent inversion and eversion of the ankle.

Abstract: A fluid bladder including a check valve inturned within the bladder. The bladder is formed of two thin sheets of plastic material sealed together around the periphery of the bladder. The check valve is formed of an extended mating pair of strips of the same two sheets of plastic overlying one another and heat bonded together by a high frequency electric field along two substantially parallel lines to form a central flow channel with a closed gap-free configuration. In forming the check valve, at least one pair of electrodes are employed, and insulating material is used to enclose the electrodes so that the two sheets of plastic material are maintained parallel and in contact with one another during welding and the subsequent cool-down interval, thereby assuring reliable check valve operation.

Abstract: A combined check valve and relief valve assembly for permitting the free of a fluid in a first direction and for selectively preventing backflow. Backflow occurs only upon depression of a compression spring-loaded cylindrical valve actuator housed within the valve body. The valve assembly comprises a valve body having an inlet and outlet port which are adjacent to an upper and lower cylindrical bore respectively, thus providing a flow path. A resilient duckbill valve is mounted within the cylindrical bores. A compression spring-loaded valve actuator is also received, lossely, within the valve body and is provided with a stem at the end of the valve actuator, proximate to the opening of the duckbill valve. Fluid passing through the upper cylindrical core around the valve actuator opens the lips of the duckbill valve permitting free passage therethrough. Back pressure seals the lips of the duckbill valve so that the valve becomes a check valve.
