Dec 7, 2004

Appl. No.:

11/007720

Inventors:

Peter C. Salmon - Mountain View CA, US
Howard Johnson - Twisp WA, US

International Classification:

H01L 21/66
H01L 29/40

US Classification:

438 18, 257778

Abstract:

An electronic socket is described for providing either or both temporary and permanent attachments of electronic components to a substrate having interconnection circuits. The socket includes wells filled with a conductive fluid or paste for temporary attachment to the mesas of an electronic circuit. The wells are connected to selected traces of the substrate having interconnection circuits. The temporary connection may be used to produce known good die (KGD), including support of burn-in and high-speed functional test. The mesas can be filled with a material that is hardened after insertion of the mesas for permanent connection of the electronic circuit to the interconnect circuit.

International Classification:

H04L 12/56

US Classification:

370389

Abstract:

A management application can automatically coordinate the decommissioning of ports in a switch, ensuring that ports are gracefully taken out of service without unnecessary interruption of service and triggering of automatic recovery functionality that may occur during manual decommissioning of ports. Embodiments may provide for decommissioning of F_ports only, E_ports only, or both F_ports and E_ports. Where link aggregation is provided for in the fabric, decommissioning of a port in a link aggregation group may be performed if there are other operational links in the group. Decommissioning of a non-aggregated port (or the last operational port in a link aggregation group) may be performed if there is a redundant path available.

Amy O. Hurlbut - San Francisco CA

Assignee:

Echelon Corporation - Palo Alto CA

International Classification:

G06F 1110

US Classification:

371 372

Abstract:

An error detection and correction method and apparatus is described which permits the correction of double errors using a (15,11) Hamming code and a parity bit. The Hamming code and parity bit allows the detection of double errors. A modulated waveform carrying the binary data is examined for anomalies such as noise pulses. A hint signal is generated based on the anomalies which points to a suspect bit. The state of this bit is changed to correct for double errors.

Amy O. Hurlbut - San Francisco CA

Assignee:

Echelon Corporation - Palo Alto CA

International Classification:

H04M 1104

US Classification:

340310A

Abstract:

In a power line communication apparatus, data is redundantly transmitted on a first and a second carrier where the carriers are separated by a predetermined number of Hz. In the receiver two channels are used, one for each of the carriers. The noise level in each channel is independently determined. A switching network is used to allow the selection of the channel with the lesser noise or if the noise is approximately equal in both channels, the signals in the channels are combined.

Echelon Corporation - Santa Clara CA

International Classification:

H04M 1104

US Classification:

34031002

Abstract:

A power line communication (PLC) apparatus wherein a carrier is derived to avoid determinable interference harmonics. In order to transmit data on a power line containing the television interference or other determinable interference harmonics, the present invention uses redundant carriers at a frequency between the television interference harmonics. In the preferred embodiment, the first carrier is positioned at 118 KHz and the redundant carrier is positioned at 133. 7 KHz for the PLC apparatus designed for use in the United States. Other carrier frequencies are used for other countries in order to avoid interference harmonics at a slightly different frequency. The present invention includes a waveshaping and modulation circuit for generating the modulated data waveform for output over the power line. In the preferred embodiment, the waveshaping and modulation circuit includes a waveshape ROM for storing samples that represent the appearance of the carrier waveshape. Once the appropriate waveshape is selected from the waveshape ROM, the 256 discrete points of the waveshape are clocked out an interface line to a DAC, a filter, an amplifier and on to a PLC coupling network for isolating and coupling the signal onto the power line.

Appl. No.:

5/736032

Inventors:

Howard B. Johnson - Woodland CA

Assignee:

Johnson Farm Machinery Co., Inc. - Woodland CA

International Classification:

A01D 4620
A01D 7528

US Classification:

56 102

Abstract:

A vine crop, e. g. tomato harvester is disclosed which has a crop processing mechanism that is movable through a field and a rearwardly and upwardly inclined elevator or header that is pivotally connected to a forward end of the processing mechanism. A leading edge of the elevator is proximate the ground and a level control wheel is vertically movably connected to the header and positioned forward of its leading edge. The wheel is defined by a multiplicity of tines, the free ends of which engage the ground so that the wheel rolls over the ground as the harvester moves through the field. The tines have a longitudinally convex configuration facing in the direction of rotation of the wheel. A control mechanism is actuated by relative vertical movements of the wheel for raising and lowering the leading edge of the elevator in response to ground surface irregularities sensed by the wheel.

International Classification:

C06F 1110
H04L 2720
H03D 322

US Classification:

371 371

Abstract:

A power line communication (PLC) apparatus wherein transmission mode information is encoded into each data packet while maintaining immunity from single bit errors. In the present invention, a power line communication system includes a transmitter/receiver (i. e. transceiver) which is coupled to a power distribution network. Data is transmitted through the power line by the transceiver in packets. The transceiver includes a preamble generator which creates a preamble for each of the data packets and a preamble decoder that decodes the preamble of a data packet and determines word sync for the packet. The preamble generated by the preamble generator consists of a carrier detect interval, a carrier sync interval, a bit sync interval, and a word sync pattern. The transceiver may select either BPSK or QPSK transmission modes on a data packet by data packet basis by encoding information into the packet preamble. Transmission mode information is encoded into the preamble using one of two seven-bit cross compatible word sync patterns for each data packet.

Inventors:

Howard B. Johnson - Woodland CA

Assignee:

Johnson Farm Machinery Company, Inc. - Woodland CA

International Classification:

A01F 1100

US Classification:

460 96

Abstract:

The invention provides a drum shaker apparatus for use in seed or vine crop harvesters with improved effectiveness in removing seeds or fruit from the plant portion of the crop. The drum shaker includes a rotatable drum to which is mounted a counterweight mechanism having at least three rotatable counterweights, each counterweight having an axis of rotation spaced apart from its center of mass, and means for rotating the counterweights in a phased relationship. Usually, the drum is rotated at a constant angular speed, onto which is superimposed the oscillatory movement caused by rotation of the counterweights. The drum shaker further includes tines extending outward from its surface for engaging the crop. The present invention provides tines of varied stiffness arranged on the drum so as to create relative movement of adjacent tines, which tends to shear the seeds or fruit from the plants. The drum shaker of the present invention offers greater harvesting efficiency, compact size, reduced maintenance and longer life than known shaker-type harvesters.
