Abstract: An interactive cat toy has a base, a motor, a controlling circuit board electronically connected to the motor, a reduction assembly connected to a shaft of the motor, a rotating seat connected to the reduction assembly, a support plugged into the rotating seat and a fake bait fixed to the support. The motor, the controlling circuit board and the reduction assembly are mounted in the base. The rotating seat is mounted on the base and has multiple plug-on holes with different inclination angels. The motor driven to rotate by the controlling circuit board drive the rotating seat through the reduction assembly, so a rotating speed of the rotating seat is slower than that of the motor. Since the support can plug into one of the multiple plug-in holes, so a position of the fake bait is adjusted. Therefore, the cat toy provides a safe and varied playing ways.

Abstract: The “Chew Toy Safety Indicator” is a safety mechanism design for pet chew toys that is distinguished by having a green (color similar to the green in a traffic light) outer wear layer and a red (color similar to the red in a traffic light) inner layer. If the green wear layer is compromised to where the red can been seen from the outside of the chew toy, this indicates to the pet owner that the pet chew toy design is no longer safe for the pet to use. Using the well-known color-coding indicator system where “green means go” and “red means stop” should be the most recognizable and safest approach to chew toy safety. This “Chew Toy Safety Indicator” when combined with the toy's design for indestructibility should lesson or eliminate the possibility of blockages that historically have hurt and in worst case scenarios kill pets.

Abstract: Current product offerings do not provide for a light-weight, portable dog restraint system for soft terrain, particularly for beach locations. Many states have enacted laws that require a dog to be on a leash while on a beach. This requirement makes it difficult for dog owners to restrain their dogs and simultaneously enjoy the beach. The challenge is to find a way to provide enough resistance to restrain a dog in a soft terrain setting. This challenge is addressed by a product which allows for appropriate weight to be added to the restraint system on location. The restraint system consists of a hollowed receptacle which can be filled with sand or water at the beach location. The hollow receptacle is then closed by a sleeve that screws into the hollow base. The sleeve consists of a center core wrapped by a pipe and eye-bolt system that rotates 360 degree around the center core. This allows the dog to be tethered, but have a free range of motion around the restraint system base.

Abstract: An internal combustion engine comprises an intake tract in which a throttle valve is disposed. The engine also comprises a camshaft which acts on gas inlet valves associated with respective cylinders. A phase-adjustment device is used to adjust a phase between the camshaft and a crankshaft. A desired air mass flow in a combustion chamber of the cylinder is determined depending on a charge requirement requested by the driver.

Otherwise, the desired air mass flow is adjusted by varying the opening angle of the throttle valve.

Abstract: In a vehicle incorporating an internal combustion engine having in-cylinder injectors and intake manifold injectors and performing engine intermittent operation control, at the end of vehicle operation, the fuel pressure is decreased in both a high-pressure delivery pipe and a low-pressure delivery pipe by actuation (opening) of an electromagnetic relief valve and by stop of operation of a low-pressure fuel pump. This prevents deterioration in emission performance at the next engine start attributable to fuel leakage due to degradation in oil tightness of the injectors during the operation stop period. When the engine is temporarily stopped by engine intermittent operation control, while the low-pressure fuel pump is stopped, actuation (opening) of the electromagnetic relief valve is prohibited. At the engine restart after temporary stop, the fuel in the high-pressure delivery pipe having its pressure secured at a certain level is injected to quickly start the engine.
