Title: Management of wireless control channel
Inventor: TU MING-HSU
IPC: H04J3/16
Filed: 1999-11-09
Granted: 2004-04-27
Abstract: A method that selects one of a plurality of priority schemes for scheduling messages for one of cyclically repeating sets of time slots of a control channel based on at least one of a plurality of characteristics of the state of the control channel. The state of the control channel is all information regarding what has arrived, what is queued, and what has been transmitted.  This includes the status of the queues, the messages awaiting transmission, along with their type and the time they have been waiting, the sequence of past transmissions, as well as other information. In one embodiment, in a control channel of a TDMA system where the hyperframe number is the characteristic used to select the priority scheme, a priority scheme is selected that assigns a voice page highest priority when the hyperframe number is an even number, and that assigns an R-DATA SPACH  notification highest priority when the hyperframe number is an odd number. In another embodiment of the invention, if there is a packed airlink message, the packed airlink message is scheduled in the time slot. If there are no packed airlink messages, then the method dynamically alters the priority of messages based on whether there is a voice page or an R-DATA SPACH notification in the message queues since at least the end of the time slot construction period of a corresponding time slot of a previous hyperframe. If there are no such messages and there is a non-packable message, the non-packable message is scheduled in the time slot, although if there are no non-packable messages and there is a voice page or R-DATA SPACH notification, it is packaged in an unpacked airlink message that is scheduled in the time slot. However, if there is a voice page or an R-DATA SPACH notification in any of the message queues since at least the end of the time slot construction period of the corresponding time slot of the previous hyperframe, the voice page or R-DATA SPACH is packaged in an unpacked airlink message that is scheduled in the time slot. This significantly reduces both the number of messages that are blocked and the number of messages timed out.

Title: Optical channel cross connect for telecommunication systems in wdm technology (wavelength division multiplexing) having a double spatial switching structure of optical flows strictly not blocking and interposed functional units operating on single channels
Inventor: ROTOLO SALVATORE
IPC: H04Q11/00
Filed: 1999-12-22
Granted: 2004-11-23
Abstract: It is described an optical cross-connect for the switching of optical channels at variable bit-rate (up to 10 Gbit/s), wavelength division multiplexed on bi-directional optical fibres forming the transmission backbone of a transport network; in particular the cross-connect can be interfaced to fibres crossin g the nodes of a ring having large territorial extension, provided with protection fibres. The cross-connect includes a spatial Split & Select input stage of WDM aggregates, followed by a set of channel filters tunable on the whole optica l range occupied by the channels, which jointly form a structure strictly not blocking the access to the channels by a set of bridge units whose functionality is selectable on a per-channel basis, such as for instance: transit, drop/insert, regeneration, etc. An output optical spatial Split & Select stage connec ts in a strictly non-blocking way the single channels from bridge units to optical multiplexers that reconstruct the WDM aggregate on the output fibres. The duplicated architecture of the bridge units for the protection fibres enable s the protection of each single local drop/insert channel

Abstract: The present invention relates to a switch device for controlling electrical equipment. Such a switch device comprises a body piece (15), a sliding member (14) and contact surfaces controlled by the sliding member (14), means for latching the sliding member (14) into a closed/open position of the switch and for unlatching the sliding member (14) from said positions, a spring-arming plate (11) and switch actuator springs (10). The invention is implemented by making a slot (33) into the sliding member (14) that controls the second movable set of contact surfaces in the switch and adapting compatible interlock means (34) to the housing or body piece (15) of the switch, said interlock means serving to inhibit the movement of said sliding member (14) by virtue of partially entering the slot (33) made into the sliding member (14). Additionally, the spring-arming plate (11) is provided with a projection (32) capable of covering the slot (33) made into the sliding member (14) and thus preventing the interlock means (34) from inhibiting the movement of the sliding member (14) when the switch is being opened or closed.

Abstract: A profile member of hybrid composite materials including alternating layers of metal and fiber-reinforced composite is fabricated by three successive steps. In a first step, wet composite prepreg layers impregnated with a binder are alternately stacked with metal layers, so that the uncured binder wets the surfaces of the metal layers. Next, the initial uncured layer structure is plastically deformed using successive pressure or bending deformation steps until a prescribed cross-sectional contour of the layer structure is achieved. Finally, the formed layer structure is supported and fixed in an autoclave, in which the binder is cured under an applied mechanical pressure and elevated temperature, to form the finished profile member.
