Abstract: A light source structure of a backlight module comprises: a bar-shaped light source; and a group of complementary color light emitting diodes mounted at both ends of the bar-shaped light source. The bar-shaped light source is composed of several light emitting diodes having complementary light colors. The luminous intensity of outermost light emitting diodes of the bar-shaped light source is 30 to 70% of average luminous intensity of the other equal color light emitting diodes. The complementary color light emitting diodes have light colors complementary to that of the outermost light emitting diodes of the bar-shaped light source. The luminous intensity of the complementary color light emitting diodes is 10 to 50% of average luminous intensity of the other equal color light emitting diodes of the bar-shaped light source. Consequently, the non-uniform mixing of lights on edges of the backlight module and the producing of bright point can be avoided.

Abstract: A piston structure of a toy gun is disclosed. An air induction passage and at least an air inlet are formed on the piston. In addition, a control device is applied to the piston for correspondingly opening or closing the air inlet according to the movement of the piston.

Abstract: A cylinder tube of a toy gun is disclosed. A cylinder head is mounted on the cylinder tube of the toy gun. A tube passage is formed to penetrate through the cylinder head. Several air induction passages are formed circularly around the tube passage. A control device is applied to the air induction passages for opening or closing the air induction passages according to the forward or backward movement of the piston. As a result, much more air can be sucked into the air storage chamber immediately after the backward movement of the piston.

Abstract: A memory management method and a memory architecture for transmitting ultra-wideband (UWB) prioritized channel access (PCA) frames are provided. The method comprises the steps of assigning a pre-load queue to each of a plurality of access categories for storing UWB PCA frames to be transmitted, and, when one of the access categories gains transmission opportunity (TXOP), assigning a common area queue to that access category for storing UWB PCA frames to be transmitted. Moreover, when a UWB PCA frame in one of the pre-load queues reaches a predetermined size, the access category corresponding to the pre-load queue starts its backoff state machine in order to gain the TXOP.

Abstract: A routing tool allows a user to create a set of routing templates, each specifying the shape of a routing corridor and identifying the corridor's terminal edges. Each routing template also specifies a set of constraints on routing of an unspecified number of conductors that are to be routed between the corridor's terminal edges. To direct the tool to create a routing plan for a particular set of conductors in a particular routing space, the user selects one of the routing templates and modifies the routing template if necessary to adjust the specified shape of the corridor to match that of the particular routing space or to adjust its specified routing constraints if necessary to accommodate any particular routing constraints to be imposed on that set of conductors. The routing tool then processes the modified routing template to generate the routing plan for routing the set of conductors between the terminal edges of the specified corridor in a manner that satisfies the specified routing constraints.
