Title: Echo canceller coefficient adaptation
Inventor: MURAOKA SHINYA
IPC: H03H21/00
Filed: 1995-08-25
Abstract: An echo canceller (30) cancels an echo signal produced on a transmission path (14) on the basis of a received signal received through a reception path (15). The echo canceller comprises an adaptive filter (31) for producing a pseudo-echo signal from the received signal in accordance with tap gains. A producing section (19, 20) produces an error signal representative of an error level between the echo signal and the pseudo-echo signal. A supplying section (21, 32) supplies the adaptive filter with selected ones of the tap gains memorized in a memory section (18) when the error level is less than a predetermined threshold level. The adaptive filter renews the selected ones of the tap gains into renewal tap gains in accordance with the received signal and the error signal to store the renewal tap gains as the selected ones of the tap gains in the memory section.

Abstract: A sensor bracket for mounting an anti-lock braking sensor is welded to an axle with a welding method that causes a portion of a bracket preform to be consumed to form the weld joint. In one preferred embodiment, an outer end of a stem of the bracket is formed of a material that will be made molten by an arc between the bracket and the axle. A fluxing agent is preferably mounted on an extreme end of the stem to initially ignite and clean the area on the axle, and further insure that the other portions of the bracket will become molten. The method preferably includes supplying a current through the bracket preform and bringing the bracket preform towards the axle. The axle is grounded, and as the bracket preform is brought adjacent to the axle, an arc is formed between the two. Outer portions of the bracket preform thus become molten. A fixture for mounting the bracket preform continues to bring the bracket preform towards the axle for a predetermined period of time. After predetermined period of time, the current is disconnected. The bracket fixture continues to hold the bracket against the axle such that the weld joint may solidify. The inventive use of a welding method in which the bracket preform is consumed to secure the bracket preform to the axle provides for a secure connection. Moreover, this welding method allows the use of automated assembly techniques to secure the sensor bracket to the axle.

Abstract: The configuration of an optical head is such that it enables movement of and setting of the position of a laser light source along an optical axis to either a first position which corresponds to the position for which an objective lens is designed to accommodate an optical disc having a first substrate thickness, and a third position which is between the first position and a second position at which the aberration with respect to an optical disc having a second substrate thickness, which is different than that of the first optical disc, is minimum. By establishing this third position as a position at which not only is there a reduction in aberration with respect to the second optical disc, but also at which there is no significant reduction in the allowable amount of lateral skew of the laser light source from the optical axis, it is possible to prevent a significant worsening of aberration characteristics, even if the laser light source is skewed from the optical axis.

Abstract: Control of vibration dampers in a car's suspension is proposed depending on signals from a sensor which measures the cyclic movement of the wheels relative to the chassis. For a preset time span, an increased damping is given if a threshold of this movement is exceeded. Strongly increased damping is given for movement above a first threshold. Depending on the frequency that a lower threshold is exceeded over a certain time period, the damping is increased in steps to a lower value than for the first threshold. The time period is bigger than the period of the chassis resonance for the car. As the lower threshold is exceeded, the damping is increased by a single step.

Abstract: A hanging bracket is initially secured to an electric
outlet box. The hanging bracket includes on one of its ends, two
canopy hooks with a screw hole located therebetween. The other end
of the hanging bracket includes a single screw hole. A canopy
includes two spaced slots shaped and located to receive the two
canopy hooks of the hanging bracket. With the canopy hooks
extending through the corresponding slots in the canopy, a fan
assembly is pivotally mounted on the hanging bracket. It is then
possible to connect the lead wires of the outlet box and the wires
of the fan assembly. All that is then required is to pivot the
canopy with the associated fan assembly about the canopy hooks into
a vertical orientation. No additional lifting of the fan assembly
independent of the fan assembly being supported by the hanging
bracket is required. A single screw is inserted through the canopy
into the screw hole in the hanging bracket at the end of the
hanging bracket opposite to the end which includes the canopy
hooks. There is an automatic alignment between the hole in the
canopy and the hole in the hanging bracket when the fan assembly is
pivoted into a vertical orientation. As another safety precaution,
a second screw is inserted through the screw hole in the canopy and
into the screw hole in the hanging bracket located between the two
canopy hooks.

Abstract: An efficient memory retrieval/storage schemes for a fault tolerant memory control system
for a computer system having a host processor, a mass storage memory and a system interconnect.
The memory control system includes a primary memory controller and a backup memory controller
with taps between the memory controllers to increase fault tolerance. Data is transferred between
the host processor and the mass storage memory in the form of data packets. During a write
operation, instead of receiving a data packet from the host processor, storing the data content,
retrieving the data and then generating a new data packet for the mass storage memory, the memory
controller redirects the data packets without the need to copy the data into the controller cache.
Similarly, during a read operation, instead of receiving a data packet from the mass storage memory,
storing the data content, retrieving the data and then generating a new data packet for the host
processor, the memory controller redirects the data packets without the need to copy the data into
the controller cache. Upon receipt of the data packets, verification packets are sent from the memories
devices to the memory controller which then sends a confirmation packet to the host processor.
Advantages of the present invention include reduced load on the system interconnect, reduced
latency in backing up data, and reduced latency in recovering from partial system failures. In
addition, the change in software and hardware needed to implementation such a solution is minimal
since most of the backup functionality is provided by existing hardware.
