  • Patent number: 6670587
    Abstract: The present invention is a self heating thermal protector located in close proximity to an incandescent light fixture for controlling the flow of current to the associated lighting fixture by measuring the rate of heat flow from a dedicated heat source. Current is permitted to flow to the lighting fixture when the temperature of the self heating thermal detector is sufficient to avoid deterioration of electrical components such as plastic parts and wire insulation in the associated fixture. The thermal detector interrupts the flow of current to the associated fixture when the temperature of the self heating thermal protector increases to a temperature that is not safe.

  • Patent number: 6639769
    Abstract: An arc fault circuit interrupter (AFCI) device functions to provide protection from potentially dangerous arc faults. The arc fault detector can be used stand alone or in combination with circuit interrupting devices such as IDCIs and ALCIs. The AFCI device detects both AC line frequencies and high frequencies associated with arcing. Both average and instantaneous values of both AC line frequency and high frequency arcing signals are processed to generate an arc fault signal. The trip mechanism of the device trips on the occurrence of either an arc fault or a ground fault. The device allows the arc detector to differentiate between destructive high level arcing and low level arcing such as generated by typical household appliances and equipment. This serves to decrease the occurrence of false tripping.

  • Patent number: 6614756
    Abstract: A method of detecting a signaling congestion situation in a transmitter within a communications switch and for handling and recovering from the congestion. The method functions to (1) monitor the level of the transmit queue for each output port and (2) to monitor the level of the signaling message buffer memory pool for all ports. When the levels of either pass predetermined thresholds, the signaling congestion state is declared. Once the signaling congestion state is declared, the call control or equivalent entity in the communications device stops routing new calls from/towards all ports that are in the signaling congestion state. The call control continues to handle existing calls from/towards ports that are in the signaling congestion state.

  • Patent number: 6611525
    Abstract: An apparatus for and a method of learning MAC addresses in a Local Area Network (LAN) Emulation (LANE) network implemented over an Asynchronous Transfer Mode (ATM) network. The LEC or LES is adapted to detect when the ATM address associated with a MAC address is no longer valid. Once an invalid ATM address is detected the existing entry can be updated or deleted. A LEC_ID table holding LEC_ID to ATM address bindings is created. Each frame received by the LEC is sniffed in order to find mismatches between the ATM address and the LEC_ID. Optionally, an LE_ARP request message can be forwarded to the LES for learning the new binding. If the MAC address is not found in the LE_ARP table, an entry can be created and added to the table. In another embodiment, the LES is adapted to detect when the MAC to ATM address binding stored in the internal LE_ARP cache is no longer valid. The LE_ARP table is populated by examining LE_ARP request and response sent and received by the LEC.

  • Patent number: 6611406
    Abstract: A ground fault circuit interrupter (GFCI) with built in intelligence is described that includes circuitry to automatically indicate a device miswiring condition. When a GFCI is wired with its AC and LOAD terminals reversed, downstream devices are still protected in the event of a ground fault but the duplex receptacle on the GFCI itself is not. The invention incorporates miswiring sense circuitry that automatically triggers the generation of visual and audible alarms in the event a miswiring condition is sensed. The invention employs an alarm inhibiting technique that incorporates sense circuitry connected to the AC terminals on one side of the internal GFCI switches or relays and alarm generation circuitry connected to the LOAD terminals on the opposite side.

  • Patent number: 6609261
    Abstract: A mattress resistant to bursting at the seam binding joining the upper and side tickings when subjected to flame conditions, is disclosed. The binding includes a tape overlying the junction of the fabrics defining the top and side tickings. The tape and ticking components are held together by a stitching thread such as lock stitching penetrating the tape, the ticking junctures and the tape again at an opposite side of the binding. The tape is selected to be thermoplastic, fire retardant and flowable at a temperature substantially lower than the char temperature of the thread which is thermo set. As a result of this combination, a flame directed against the binding will first induce the thermoplastic tape to melt and flow around and into the binding thread protecting the thread from charring and consequently losing its tensile strength for a significant period of time.

  • Patent number: 6606321
    Abstract: A method of establishing calls between an ingress MPC (the calling party) and an egress MPC (the called party) in MPOA enabled ATM based networks. The call establishment method utilizes the call request SETUP, CONNECT and CONNECT_ACK messages in creating the shortcut VCC between ingress and egress MPCs. The calling party is adapted to send a READY_IND message in a reliable manner to the called party indicating that it is ready to receive frames over the shortcut VCC. The called party starts sending data over the shortcut VCC only when it knows that the calling party is ready. The called party knows the calling party is ready upon receipt of a READY_IND message or at least one data frame on the shortcut VCC. The calling party knows that the called party is ready to receive frames when it receives the CONNECT message. Since the READY_IND message sent by the calling party may get lost, the calling party is adapted to re-send the READY_IND message repeatedly until it is certain the called party has received it.

  • Patent number: 6591317
    Abstract: A queue having a ‘duplicate’ counter associated with each entry whereby duplicate data is not stored in the queue. Before data is placed in the queue, the queue is searched for an entry matching the data to be written. If a match is found, the duplicate counter associated with the entry is incremented. Further, if a match is found and the data stored therein is inconsistent with the current data, the contents of the queue are updated and the duplicate counter associated with the entry is reset to one. If a match is not found, the data is written to the queue and the duplicate counter associated with the entry is initialized to one.

  • Patent number: 6587467
    Abstract: VC multicast implementation scheme utilizing VP tunneling over public ATM VP switched networks utilizing P2P and P2M connections to provide VC multicast capability to the attached private ATM networks. The border ATM VC switch in each private ATM network is connected to the ATM VP switch in the public ATM network via a physical interface adapted to carry one or more P2P VP tunnels. A P2P VP tunnel is established from each VC switch to all other VC switches connected to the public ATM network. A dedicated P2M VP tunnel is established between the source VC switch to each of the destination VC switches connected to the public ATM network. For each multicast connection to be established, a VPI/VCI value pair is allocated over the dedicated P2M VP tunnel used to transmit data associated with all P2M calls for all the P2P VP tunnels carried by the physical interface.
