Title: Customer information announcement service
Inventor: QUATSE GINA
IPC: H04M3/54
Filed: 1998-04-16
Abstract: A method for notifying customers, using customer information announcements, of a change in their telephone numbers due to an area code split and for notifying callers of such customers of the new telephone numbers. In one aspect, customer information is announced during completion of a telephone call placed by a calling party to a called party. A telephone number of the called party is received at a telecommunications network from the calling party. A first message indicating that the telephone number of the called party will be changed is sent to the calling party from the telecommunications network and the call is connected to the received telephone number, if the telephone number of the called party will be changed in the future. A message indicating that the telephone number of the called party has been changed is sent to the calling party from the telecommunications network and the call is forwarded to a new telephone number, if the telephone number of the called party has been changed.

Title: Thermal switch
Inventor: QUINN WILLIAM F
IPC: H01M50/583
Filed: 1998-11-20
Abstract: A thermal switch assembly includes a dielectric spacer and a switch blade member of shape memory metal sandwiched between a pair of flat metal plates. The spacer provides a cavity between the plates, and the switch blade member has a switch blade portion projecting into the cavity. The switch blade member has a mounting portion engaging one of the metal plates, and the switch blade portion normally is under bending stress in engagement with the other metal plate to provide a current path between the plates. At elevated temperatures, the switch blade portion of shape memory metal moves out of engagement with the other metal plate to interrupt the current path. Fasteners integral with the dielectric spacer cooperate with the metal plates and the switch blade member to hold the switch assembly together with the spacer and the mounting portion of the switch blade member compressively sandwiched between the metal plates.

IPC: B25C1/14
Filed: 1996-07-30
Abstract: Disclosed is a combustion-powered, fastener-driving tool comprising structure defining a combustion chamber having a combustion chamber volume, structure defining a piston chamber communicating with the combustion chamber, a driving piston movable within the piston chamber between an initial position and a terminal position, and a driving blade mounted to the driving piston so as to be conjointly movable with the driving piston. The driving piston, the driving blade, and the piston chamber are arranged so that combustion in the combustion chamber imparts energy to the driving piston and the driving blade so as to drive the driving piston and the driving blade from the initial position toward the terminal position, through a piston displacement volume, with the driving blade preceding the driving piston. The ratio of the piston displacement volume to the combustion chamber volume is sufficient to enable the driving blade to transfer more than one half of the maximum, transferable energy to a fastener engaged by the driving blade as the driving piston and the driving blade approach the terminal position. Preferably the ratio is sufficient to enable the driving blade to transfer more than eight tenths of the maximum, transferable energy to a fastener engaged by the driving blade as the driving piston and the driving blade approach the terminal position.

Abstract: An echo cancellation method and apparatus (20) determines whether a window W(m) of samples on an incoming communications path (30) contains silence, the window W(m) including the sample obtained at time t(m) and prior samples. If the window W(m) contains silence, coefficients of an adaptive filter (52) of the echo canceller (20) are set to silence detection values prior to receipt of a sample at time t(m+1). 1f the window W(m) does not contain silence and there is no double-talk, the sample obtained at time t(m) is used to update coefficients of the adaptive filter; the adaptive filter as updated generates an echo estimate after a sample is obtained at time t(m+I); and, the echo estimate is used to modify a signal on an outgoing communications path (32).
