The container has a closure with a fitment that attaches to the container. The fitment has separate bottom receptacle areas on one side and a top receptacle on the other. The separate receptacle areas are each exposed to different compartments within the container. The top receptacle area is connected to each of the separate receptacle areas by conduits. A selection head is provided having a pour spout and a plurality of baffle chambers. The pour spout has an open central conduit, wherein only some of the baffle chambers are open to that central conduit. The baffle chambers are received within the top receptacle area of the fitment. Different combinations of the baffle chambers selectively align with different conduits as the selection head rotates within the fitment.

Abstract: A system and method of tracking physical activity of a person in order to help motivate that person to add more exercise to their lives. Each participant is provided a motion sensor that detects forces incurred by the participant. The motion sensor creates electronic data that corresponds to the forces detected. The data is analyzed to determine whether or not exercise has been performed. The analysis can also determine the type of exercise performed, when the exercise was performed, and the duration of the exercise performed.

Abstract: A circuit for monitoring the functionality of an electrical element. A primary power supply provides direct current to the electrical element at a current sufficient for the electrical element to operate. A Schottky diode is disposed between the primary power supply and the electrical element, wherein the electrical element draws its operational current through the Schottky diode when in operation. A reverse bias power supply is provided. An opto-isolator is disposed between the reverse bias power supply and the electrical element. The electrical element draws a secondary current from the reverse bias power supply through the opto-isolator. The opto-isolator creates an output signal that is indicative of the secondary current. The output signal is used to control a remote failure indicator. When the electrical element fails, the current flowing through the opto-isolator stops. This triggers the failure indicator and informs a user as to the failed status.

Abstract: A cooperative position location device (CPLD) that integrates a broadcast digital transmission (BDT) receiver, a data link transceiver, and a displacement sensor; a computer program product tangibly stored in computer-readable media; and associated methods for receiving and processing special codes embedded in BDT signals from a plurality of transmitters to produce time of arrival (TOA) measurements thereof; for sending and receiving special messages between cooperative position location devices (CPLDs) to produce time difference of arrival (TDOA) of common events of BDT at and time of flight (TOF) measurements between the CPLDs; and for integrating differential and relative ranges between CPLDs to a plurality of BDT transmitters and displacement measurements to yield a joint position solution of the CPLDs.

Abstract: A sand bunker construction having different porous layers that are built up upon the ground and internal drainage. The first layer is a layer of aggregate. The aggregate is gravel having an aggregate size large enough to avoid displacement from rain and irrigation spray. A porous matrix is placed upon the first layer. The porous matrix is made from gravel aggregate that is coated with a binding agent, such as asphalt, tar, or cement. The binding agent is added in amounts only sufficient to bind the aggregate. The result is a porous matrix having numerous voids between the various pieces of aggregate. A covering of sand is applied over the porous matrix. The sand fills the top voids in the porous matrix and buries the porous matrix. Due to the rough texture and porosity of the porous matrix, the porous matrix holds the sand in place and greatly inhibits erosion.

Abstract: A system and method of customizing a flush toilet to help train an animal to utilize the toilet when making waste. A primary tray is provided. The primary tray is placed over the toilet. An opening is formed in the primary tray. If a pet in training becomes tentative, the opening is reduced in size or eliminated by the use of a supplemental tray. The supplemental tray is sized to cover only the part of the primary tray that holds litter. With the litter removed, the supplemental tray is placed atop or under the primary tray. If no opening is desired, no opening is formed. If a smaller opening is desired, an opening of the appropriate size is made in the supplemental tray. The supplemental tray is then filled with litter and is used to train an animal as if it were part of the primary tray.

Abstract: An emergency pressurization system for an aircraft having an air pump that is powered by bleed air from an engine of the aircraft. Although the air pump is powered by engine bleed air, the air pump draws ambient fresh air from outside the aircraft, compresses the fresh air to a predetermined pressure and pumps compressed fresh air into the pressurized cabin of the aircraft without ever exposing the compressed fresh air to the engine air. The speed of the air pump is selectively controlled as a function of cabin pressure and/or bleed air pressure. In this manner, the cabin is maintained at a constant safe pressure.

Abstract: In an embodiment, a spool for a trimmer head has a structure for guiding the trimmer line around a region for a driveshaft. In an embodiment, a component (e.g., a turn knob or a stop) is attached to the spool so that after determining the orientation in which to install the spool, the user is unlikely to install the spool in another orientation, even though the spool is invertible. In an embodiment, the turn knob also includes a structure that allows the turn knob to be used as a tool (e.g., as a wrench or screw driver) that facilitates disassembling the trimmer head.

Abstract: A toy assembly that has an impact surface made from an array of taut strings. The hardness of the impact surface is a function of the tension present in the strings. The toy assembly has two plates that are spaced apart. The two plates are held apart by a post. One or more of the plates may be selectively adjustable in position along the post. A plurality of strings extends between the first plate and the second plate. Each of the strings is maintained in tension to create a resilient impact surface. The strings are maintained in tension by the use of spring clips and/or by adjusting the distance between the two plates.

Abstract: A system and method for mounting gaming machines to a support, in a manner that enables gaming machines to be quickly and easily installed and removed. A mounting base is provided for each gaming machine. Ports are formed in the support that are shaped to receive the mounting bases. Once a gaming machine is placed on the support, the mounting base passes into a port and the gaming machine sits flush on the support. Mechanical fasteners are then used to lock the mounting bases into the ports so that the gaming machines cannot be removed from the support. The gaming machines are also connected to power cables and signal cables under the top surface of the support.

Abstract: A projectile device having a suction cup head made of a novel foam. The foam used in the suction cup head has an open cell density within the foam of between five percent and twenty percent. The suction cup head has a face surface of a first diameter. A shallow concavity is formed in the face surface. The concavity has nearly the same diameter as the face surface, however, the depth of the concavity is no more than one-tenth of that diameter. Furthermore, the face surface of the suction cup head is proportionally large, being at least twenty-five percent as wide as the entire projectile device is long. The combination of a large suction cup head, a shallow concavity and a soft, semiporous foam enables the suction cup head to adhere to both smooth surfaces and rough surfaces.

Abstract: A hydrogen purification system that is used to separate hydrogen gas from a mixed gas source. The hydrogen purification system includes a hydrogen separator. Within the hydrogen separator is a first chamber into which the mixed gas source is fed. A plurality of tubes extend into the first chamber. Each of the plurality of tubes is permeable only to hydrogen. Gap spaces exist within the first chamber in between any of the plurality of tubes that are arranged in adjacent positions. The mixed source gas passes through the gap spaces as it permeates the first chamber. The mixed gas source spreads thinly over the exterior of the tubes within the confines of the gap spaces. Hydrogen from the mixed gas source permeates thru the tube walls and into the interior of the tubes that are in parallel and the hydrogen is collected in a chamber.

Abstract: A burp cloth device that is designed to protects a mother's hand while feeding and burping an infant. In this manner, the amount of an infant's spit-up that contacts the mother's hand is limited and the mother's skin need not become irritated by the contact with stomach acid or the need for excess washing. The burp cloth device has a hand pouch that defines an open interior. The hand pouch has at least one side opening that provides access into the open interior by a user's hand. A cloth panel extends below the hand pouch. The cloth panel has side edges that extend downwardly to a free hanging end. Secondary features, such as a catch pocket, protruding tabs and teething surfaces can be added to the cloth panel.
