Abstract: An insertable pallet for unloading or acquiring objects or for loading or piling objects, particularly in a stacked position, comprising at least one live roller (101) for moving an object being unloaded or loaded along the insertable pallet (100). In the unloading mode of the insertable pallet, the insertable pallet (100) is thrust at an object seam until the insertable pallet is under-neath the object being unloaded a sufficient distance to engage at least one live roller of said insertable pallet for moving the ob-ject from its initial position along said pallet. In the loading mode of the insertable pallet, an object being loaded is moved to and preferably partially over the front of the insertable pallet by at least one live roller. The insertable pallet is appropriately posi-tioned so that when the object arrives at the front of the insertable pallet an operator can nudge the object of the insertable pallet with a minimum of physical effort.

Abstract: On décrit un système sollicitant une réaction de la part des spectateurs dans lequel chaque spectateur est équipé d'un dispositif réfléchissant (44) (ou autre source de rayonnement) qui est, par exemple, vert d'un côté et rouge de l'autre. La lumière provenant d'un spot lumineux (40) est réfléchie à partir des réflecteurs (44) et visualisée par une caméra vidéo ordinaire (24). Un ordinateur (14) reçoit l'image numérisée et traitée, crée une carte de l'occupation de la salle, et distingue les points de réflexion rouges des verts. Ces données sont ensuite traitées par l'ordinateur (14) pour projeter une image sur un écran (34) visible par les spectateurs, l'image étant commandée par les points de réflexion d'images rouges ou verts. Les spectateurs commandent ainsi conjointement l'image de l'écran, par exemple, pour participer à un vote ou à un jeu. Le système permet également de détecter le déplacement (sens et/ou vitesse) de chaque source de rayonnement dont les données sont regroupées et peut ainsi manipuler l'image de l'écran. Les sources peuvent également chacune transmettre des informations codées (tel que le code Morse ou ASCII) pour s'identifier individuellement.

Title: Method and apparatus for providing cryptographic protection of a data stream in a communication system
Inventor: FINKELSTEIN LOUIS DAVID
IPC: H04W12/00
Filed: 1994-07-11
Granted: 1998-09-22
Abstract: A method and apparatus for providing cryptographic protection of a data stream are described in accordance with the Open Systems Interconnection (OSI) model for a communication system. This cryptographic protection is accomplished on the transmitting side by assigning a packet sequence number to a packet derived from a data stream received from a network layer (110). Subsequently, a transmit overflow sequence number (124) is updated as a function of the packet sequence number (116). Then, prior to communicating the packet and the packet sequence number on a physical layer, the packet is encrypted as a function of the packet sequence number (116) and the transmit overflow sequence number (124). On the receiving side, the packet sequence number is extracted (166) from the physical layer (160). In addition, a receive overflow sequence number (174) is updated as a function of the packet sequence number (172). Finally, the encrypted packet is decrypted as a function of the packet sequence number (176) and the receive overflow sequence number (178). In addition, a transmitting and a receiving communication unit for use in a communication system which includes cryptographic protection of a data stream is described.

Title: Low power optical network unit
Inventor: FRIGO NICHOLAS J
IPC: H04B10/00
Filed: 1995-04-28
Granted: 1999-11-02
Abstract: An optical network unit for use in a switched passive  optical network utilizes the high contrast ratio between the energies of optical ringing signals and optical interrogation signals.  The receiver of the optical network unit is operated in a low power mode of operation until communication between the central office and subscriber is desired.  In the low power mode, a photodetector runs in a photovoltaic mode to charge a sensing capacitor.  An optical ringing  signal  originating  in  the  central  office when communication via the ONU is desired creates a voltage signal which is detected by a comparator circuit.  When the comparator triggers, it switches on the receiver and directs the output of the photodiode to the receiver for processing of  the  communication  signals  received  therefrom.    On completion of the call, the ONU is returned to the low power state.   When an off-hook signal  is  detected,  the ONU interrupts the interrogation signals, thereby indicating to the central office that subscriber initiated communication via the ONU is desired.

Abstract: In optimization of combinatory optimization problems, it is possible  to  perform  deterministic  as  well  as  more  or  less randomized searches.  A new allocation matrix is generated, based on a more or less coincidentally selected, but valid allocation matrix.  A check is made thereafter whether it constitutes a better solution than the old allocation matrix.  If this is the case, this matrix is used as the new starting point for the further search.  If this is not the case, the old allocation matrix is kept as the starting point for the further search.  This process is continued until the time made available for the solution has expired, or until it is determined by the method itself that no better solution can be found in the course of the instantaneously realized search.

Abstract: In a method of controlling overloads in a telecommunications network, a module (46) for detecting and monitoring overloads is provided at a node (40). The node (40) includes a module (44) for controlling access to terminal resources such as telephones and fax machines. The module (44) also detects failed calls. Upon detecting an initial failed call to a particular called party number, a counter in module (46) is initialised. The counter is incremented for each further failed call to the particular called party number and also decremented at a fixed rate. When the number of calls in the counter rises above a first threshold, the counter goes into an overload state. When the number of calls in the counter falls below a second threshold, the counter goes into a no overload state. The module (46) sends an indication of the state of the counter and the identity of the called number to a module (48) in a node (41) which sets and updates a restriction parameter. The node (41) is upstream from the node (40) in the direction of call set up and the overload status is transmitted in the backward call set up messages. The module (49) then sets the restriction parameter in accordance with the overload status of calls to the called number and supplies this parameter to a module (49) which restricts calls to the called number. Call restriction is maintained until the overload to the called number subsides completely, The invention may also be used to detect and control calls whose call identities belong to a common set of call identities.
