Title: Bandwidth management in a wireless network
Inventor: CROMER DARYL CARVIS
IPC: H04H20/00
Filed: 2003-04-30
Abstract: In accordance with the preferred embodiment, an access point provides dynamic load balancing of network bandwidth between access points within the 802.11 wireless LAN. The access point uses the RTS/CTS protocol to reduce the bandwidth available to a single device using an excessive amount of network bandwidth. The access point places a device that has been monopolizing a network channel on a Restricted List, and regulates bandwidth on the network by not returning a CTS to any client on the Restricted List. When the client's network usage drops below a policy driven threshold set by the number of network users, the client is removed from the list and the access point will respond to a RTS from the client with a CTS.

Title: Buffer device for roller blinds
Inventor: FUN FU-MEI
IPC: B65H75/48
Filed: 2003-07-18
Abstract: A buffer device for roller blinds is mounted inside the reel of the roller blinds and includes an enclosure; a clutch mechanism mounted in the enclosure and capable of switching between an engaged position and a disengaged position; and an active shaft mounted in the enclosure and capable of forming a link relationship with the clutch mechanism. One end of the active shaft extends out of the enclosure and is fastened to a rotary disk. The rotary disk can be driven by the reel and drive the active shaft for rotation and the clutch mechanism for movement. When the reel performs a forward movement and the roller blinds are lowered, the clutch mechanism is changed from an engaged position to a disengaged position in such a way that no damping occurs when the reel is releasing the roller blinds. When the reel performs a reverse movement and the roller blinds are winding up to a suitable length, the clutch mechanism is changed from the disengaged position to the engaged position, and the rotation disk activates a damping mechanism for producing a damping function, thereby providing a buffering when the reel is performing a winding operation of the roller blinds.

IPC: B29C45/77
Filed: 2003-10-31
Abstract: Return stroke of the screw is controlled according to the pressure difference between a set resin pressure and a detected resin pressure. The screw is rotated at a set speed. As soon as the difference between the position of completion of measurement and the present position of the returned screw becomes less than a predetermined value, the control of the return stroke of the screw according to the pressure difference is stopped, and the control is switched to a control according to the position difference. Therefore, a crew rotational speed command for connecting the pressure difference component between the set resin pressure and the present resin pressure from the screw rotational speed component which is reduced in proportion with the position difference is calculated to output such command.
