Patent CA-2308967-A1 (CA)
Inventor: ARCHAMBAULT SYLVAIN S
IPC: H04B10/275
Filed: 2000-05-18
Abstract: A method of wavelength allocation that allows creating a fully meshed network at the optical layer when the nodes are connected at the physical layer in a ring. The method uses a minimum number of wavelengths and a same wavelength set on each fiber, with the constraint that a wavelength is used at most once on any resource. A hop table is prepared with all nodes and all wavelengths and the origin of the table is defined by a first node and a first wavelength. For rings with more than seven nodes, an initial hop vector is defined, which is different for rings with an odd and an even number of nodes. All hops for all nodes and all wavelengths are then generated using the initial hop vector, and recorded in the hop table. After the hop table is completed, the nodes are equipped with wavelength-specific receivers and transmitters according to a source-destination table prepared from the hop table. Hop tables are also provided for rings with less than seven nodes.

Abstract: A golf club head includes a front face arranged for impact with a golf ball, a heel portion and a toe portion. A hosel has a neck connected to the heel portion of the body. The hosel contains a bore for receiving one end of a golf club shaft, and the bore has a desired orientation relative to the body. The hosel neck has an upper surface and a lower surface, and a notch is formed in the lower surface of the hosel neck. The notch has a depth that varies along its length. A critical dimension measured between the upper surface of the hosel neck and a point on the depth of the notch is less than the outside diameter of the hosel. This permits the desired orientation of the bore to be adjusted by bending the hosel neck at the notch.

Abstract: A method and apparatus for adaptively adjusting the power of a probe signal to be transmitted by user equipment based on a characteristic of received signals and system constants so as to increase the likelihood that the probe signal will be detected by system equipment of a communication system. The Doppler shift of a received pilot signal is derived and an adjustment parameter is calculated based on the Doppler shift, time interval between successive probe transmissions and system constants. The adjustment parameter is applied to the probe signal to be transmitted to compensate for the effects of fading to be experienced by the probe signal to be transmitted.

Title: Afci which detects and interrupts line side arcing
Inventor: MACBETH BRUCE F
IPC: H02H1/00
Filed: 2001-02-02
Abstract: An arc fault causes the line voltage across the line terminals of an arc fault circuit interrupter (AFCI) to change its characteristic voltage pulse shape as the line voltage is momentarily removed from the AFCI terminals after the arc extinguishes and before it re-strikes by introducing a flat voltage portion to the pulse shape. This flat voltage portion changes the voltage pulse width. An arc detector/processor detects this change in pulse width to produce a signal indicative of upstream (line side) arcing. The flat voltage portion can also be detected using clamping diodes and charging capacitors.

Abstract: A fault-tolerant client-server system has a primary server, a backup server;  and a client. The client sends a request to the primary server, which receives and processes the request, including sending the response to the client, independent of any backup processing. The response includes the primary server state information. The primary server also performs backup processing that includes periodically sending the primary server state information to the backup server. The client receives the response from the primary server, and sends the primary server state information to the backup server. The primary server state information includes all request-reply pairs that the primary server has handled since a most recent transmission of primary server state information from the primary server to the backup server. The primary server's means for performing backup processing may be activated periodically based on a predetermined time interval.  Alternatively, it may be activated when the primary server's memory for storing the primary server state information is filled to a predetermined amount.
