Abstract: A new electronic goal detector for accurately detecting and signalling when a hockey puck passes through the goal line between the goal posts of a hockey goal. The inventive device includes a set of goal sensors for mounting on the goal posts and cross bar of a hockey goal to act as a goal sensing means for detecting a puck passing through the goal line. A goal sensor is also embedded within the hockey playing surface along the goal line.  At the bottom end of one of the goal posts is a two-part connector that separates when the hockey goal is moved off of the goal line to deactivate the goal sensors. A sound generating device and a light source provide an indicating means for indicating when a puck passes into the hockey goal.

Abstract: An optical transmitter (1) includes a directly modulated semiconductor laser  (2) and a non-linear optical intensity modulator (3) which is connected in series with the output of the laser. High frequency analogue modulating signals are applied both to the laser and to the modulator. The modulator ha s a transfer characteristic such that it cancels intermodulation distortion in  the output from the laser, to give a source with an improved dynamic range. The transmitter is suitable for use in an analogue optical distribution syst em for cellular radio.

Abstract: La présente invention fait état d'une méthode de transfert pour système de communication mobile. Lorsque la station mobile reconnaît qu'elle est passée dans une zone de chevauchement, elle transmet cette information au côté réseau et, en réponse, ce dernier établit une seule voie de communication entre la station de base cible de transfert et la station de commutation commandant la station de base cible de transfert, sans établir de voie radio entre la station de base cible de transfert et la station mobile. La communication n'est toutefois pas interrompue puisque la voie de communication entre la station de base courante et la station de commutation et la voie radio reliant la station de base courante et la station mobile ne sont pas libérées, de sorte qu'il devient possible de réduire la charge de commande de transmission entre la station de base et la station de commutation de même que la charge de commande nécessaire pour commander la station de commutation elle-même.

Title: Method for overload control in a multiple access system for communications networks
Inventor: CHUAH MOOI CHOO
IPC: H04L69/14
Filed: 1998-10-08
Granted: 2003-01-28
Abstract: In the method for overload control in a wireless communications network employing On-Demand Multiple Access Fair Queuing, if the downlink/uplink buffer occupancy of the network has exceeded a high threshold, the base station determines if this is caused by a specific remote host or by a group of remote hosts. If caused by a specific remote host, the base station normally sends a flow control signal to the remote host to prevent it from sending more data, but may alternatively elect todisconnect other remotes if the remote experiencing bad performance is of a higher priority. The base station may additionally reduce the bandwidth shares allocated to any remote that have indicated tolerance for a variable allocated bandwidth. If the measured frame error rates for many remote hosts are increasing, then the base station may elect to disconnect those remote hosts that permit service interruption in order that more bandwidth may be allocated to the remaining users. If a majority of all associated remote hosts experience high uplink frame error rates, the base station may instead send a signal to a wireless hub which can coordinate the actions of other access points. Short packets queued up for so long at the base station that they exceed the time-to-live value allocated will be thrown away. The base station may also or alternatively elect to disconnect some users of a lower priority or redirect them to other nearby base stations that have a lower load. In a particular embodiment, an uplink Frame Error Rate (FER), an average uplink bit rate, a burstiness factor of uplink traffic, and a packet loss rate are measured at the base station for each remote host. Similarly, a downlink Frame Error Rate is measured at each remote host andthen each FER is sent to the base station. If an overload condition exits, connections with a Frame Error Rate that has exceeded a threshold for a specified time and that have indicated that their connections can be interrupted are disconnected. Othercombinations of the possible actions are suitable, with the exact combination being determined by the base station depending on the particular congestion conditions observed in the network.

Title: A method for porting a mobile directory number from one wireless service provider to another
Inventor: ROLLENDER DOUGLAS HAROLD
IPC: H04M3/00
Filed: 1999-02-09
Granted: 2002-12-10
Abstract: The present invention is a method for porting a mobile directory number of a subscriber from a donor wireless service provider to a recipient wireless service provider with minimum interruption to the subscriber's wireless communication service. In one embodiment, the present invention is accomplished by creating an entry for the wireless terminal in the recipient wireless service provider's home location register and a temporary pointer in the donor wireless service provider's home location register, wherein such temporary pointer will cause the donor wireless communication system to route or forward any call intended for the wireless terminal being ported to the recipient wireless communications system for completion in well-known fashion. When the porting process is complete, the temporary pointer is removed or deactivated in the donor wireless service provider's home location register.  Advantageously, coordination of the porting process is controlled by the recipient wireless service provider resulting in minimum interruption to the subscriber's wireless communications service.

Abstract: A ventilator apparatus (10) is disclosed for supplying air from a source of pressurized air (12) between a dryer (14) and a web (W) supported by a felt (F) extending around a roll (16) of a single tier drying section (18). The apparatus includes a housing (20) which is connected to the source of pressurized air. The housing defines a nozzle (22) for directing a flow therethrough of a current of air (24).    The flow is directed from the nozzle towards a diverging nip (DN) defined between the dryer and the web supported by the felt when the felt diverges away from the dryer prior to the felt extending around the roll. The arrangement is such that the flow of air compensates for an underpressure generated by the felt when diverging away from the dryer so that fluttering of the web is inhibited.
