Abstract: A sound generating pet toy is provided which includes two similarly configured pet toy components. Each pet toy component has an exterior housing and an electronics module. The electronics module includes and electronics circuit having d.c. batteries, a microprocessor which includes a wireless transceiver component, a timer, a speaker, a push button on/off switch, and a high sensitivity vibration switch sensor. The microprocessor is electrically coupled to and powered by the batteries. The microprocessors are programmed to emit a sound upon activation from a first pet toy components, and thereafter to switch the generation of the sound to the second pet toy component upon sensing movement of the first pet toy component, this switching occurring back and forth between the two pet toy components as long as movement is sensed.

Abstract: A toy a pet laser toy 100 includes a housing 101 having a front end 104 and a rear end 105 relative to the forward direction of travel. The toy has a right wheel 107 coupled to a right motor 110 and a left wheel 108 coupled to a left motor 111. The motors are independently controlled through a microprocessor 118. The toy 100 also includes a light source 126 mounted to the housing 101 at a downward angle with respect to the horizontal plane underlying the toy. With the angular mounting of the light source 126, the light produced by the light source 126 is projected upon the underlying support surface a short distance behind the rear end 105 of the toy 100.

Abstract: A method for realizing backpressure of masses of ports and a device realizing the method are disclosed. The method for realizing backpressure of masses of ports includes: detecting whether user data transmitted to a channelized physical port reaches a backpressure threshold, generating an idle frame or a series of idle frames when the backpressure threshold is reached; combining the idle frame with the user data which needs to be transmitted to the channelized physical port reaching the backpressure threshold, and transmitting the combined data; discarding the idle frame before the combined data enters the channelized physical port. The idle frame is employed in the present invention to realize the backpressure. The idle frame occupies some of the transmission bandwidth and reduces the bandwidth of user data, while the idle frame does not enter the physical port. Therefore, the aim of backpressure is achieved. The bandwidth of idle frame can be pre-configured according to the requirements.

Abstract: A system and method of storing information about tree structures. The method includes, for each given tree, identifying the nodes and the relationships between the nodes, and for each parameter, if more than one node of any of the given tree shares the parameter, then defining a scoping for the parameter to cover all of the nodes to which the parameter is applicable. The scoping includes applying one or more scope types having a varying specificity. The resulting information stored about the tree structure is substantially reduced in size in comparison to information about tree structures stored in a conventional manner, thereby reducing storage space requirements.

Abstract: There is disclosed a system and method of storing information about tree structures. In an embodiment, the method comprises: for each given tree, identifying the nodes and the relationships between the nodes; for each parameter, if more than one node of any of the given tree shares the parameter, then defining a scoping for the parameter to cover all of the nodes to which the parameter is applicable. The scoping may comprises applying one or more scope types having a varying specificity. The one or more scope types may be, for example, a scope based on the database table that information is stored in; the name of a node; the type of a node; a parent node; a particular branch of the tree; or an exact match of a pathway to a specific node. The resulting information stored about the tree structure is substantially reduced in size in comparison to information about tree structures stored in a conventional manner, thereby reducing storage space requirements.

Abstract: A cable terminal has a base having a hole, a large portion, a small portion and an annular wall therebetween. The small portion has an annular protrusion and a tilted guiding flat beside the annular protrusion. An outer member has a hole and on a sidewall of the hole is a first protrusion portion, a second protrusion portion, a stop portion and a thread in sequence. The outer member is fitted to the smaller portion of the base with the first protrusion portion crossing the guiding flat and engaged with the annular protrusion. An engaging member is received in both of the base and the outer member and has a plate against the stop portion of the outer member to move the outer member toward the base, in which the first protrusion portion is moved to where between the annular flat and the annular protrusion.

Abstract: A coaxial cable connector is constructed to include a lock nut, a shell inserted in the lock nut, the shell having a smaller front receiving section and a bigger rear receiving section and an inside annular flange at the rear end of the bigger rear receiving section, an inner jacket inserted into the lock nut and the shell and adapted to receive the center conductor of the coaxial cable, the inner jacket having a rear stop flange stopped at a step inside the lock nut and a wedge-like front flange, and an outer jacket inserted into the shell and adapted to hold down the insulative outer shell and outer conductor of the coaxial cable on the periphery of the inner jacket, the outer jacket having a beveled front section, which is forced radially inwards by the inside annular flange of the shell to stop the coaxial cable from displacement.
