Abstract:
A soldering process uses two or more different solder alloys. A first solder alloy (115) that undergoes a solid-to-liquid transition at a first temperature is coated (20) onto the solderable surfaces (105) of a printed circuit board (100). A solder paste (120) that undergoes this solid-to-liquid transition at a temperature greater than the first temperature is deposited on the coated solderable portions, and is heated to a temperature that is above the first temperature but below the second temperature. During this time, the first solder alloy liquifies, while the solder paste does not. The first solder alloy wets to the individual particles in the solder paste, and alloys to the solderable surfaces and the solder particles in the solder paste. The soldering composition is subsequently cooled (40) to solidify the first solder material, forming a solid and substantially planar coating on the solderable portions of the printed circuit board.
Abstract:
A method and apparatus for controlling communication channel access in a communication system (10) determines channel allocations (106) which represent limits on communication channel access and conforms operations of the system (10) to the channel allocations (106). The channel allocations are determined by dividing a surface which emanates signals from communication units (26) into elemental areas, collecting past traffic data (102) describing past communication channel usage by the communication units (26) located in the elemental areas, generating a traffic model (104) for a future time interval based on the past traffic data, and determining the channel allocations (106) based on the traffic model.
Abstract:
A system polynomial is determined using a plurality of system I/O data, wherein the system polynomial expresses the system output (98) in terms of the system input (96), and wherein the system polynomial has at least one linear term and at least one nonlinear term. A control polynomial (90) is determined, the control polynomial having at least one cancellation term and at least one control term, the at least one cancellation term calculated to cancel the at least one nonlinear term of the system polynomial, and the at least one control term calculated to control the at least one linear term of the system polynomial. A control output signal (92) is generated based on the control polynomial and the control input signal (94).
Abstract:
The present method (200, 300, 400) and device (500, 600, 700) modify phase two of the format set forth in the V.34 Recommendation of the International Telecommunication Union-Telecommunication Standardization Sector to prevent premature disconnection of calls between a call modem and an answer modem. The method and device efficiently ensure connection of the call for high speed data transmission over voiceband channels, by modification of one of: a phase preliminary to phase one and phase two. One implementation, in the answer modem, includes transmitting a signal having first information, followed by a Signal S comprising a guard tone and a signal SI, wherein an energy of a predetermined guard tone is greater than an energy of a predetermined range of frequencies of the Signal SI; and continuing transmitting and receiving in accordance with the modified V.34 operation.
Abstract:
A site controller (102) instructs a transcoder (121) to operate in a partial transcoding mode (401). While in the partial transcoding mode, the transcoder continuously monitors for a synchronization pattern. If the synchronisation pattern is detected within a predetermined period of time, the transcoder switches operation to a transparent mode (402). While in the transparent mode, the transcoder transparently passes compressed digital voice. If the synchronization pattern is not detected within the predetermined period of time, the transcoder switches operation to a full transcoding mode (400). Regardless of the operating mode, the transcoder continues to monitor for the synchronization pattern. Additionally, the transcoder transmits the synchronization pattern in either the partial transcoding mode or transparent mode. By detecting the synchronization pattern generated by the transcoder, other transcoders (122-123) can also switch to the transparent mode, thereby avoiding multiple format conversions.

A method (100), stacked module (200, 300 and 400), and communicator (500 and 600) are provided for packaging flip-chip bonded integrated circuits. A first integrated circuit is flip-chip bonded to a surface of a mounting unit. A second integrated circuit is mounted on the first integrated circuit using an adhesive and is wire bonded to the surface of the mounting unit.
Abstract:
User device (12) classes are established in a communications network (100). An access point (10) utilizes a first password to create an encryption key, then generates a plurality of secondary passwords for use by devices (12). User device (12) classes are established by assigning a secondary password to a respective class of users, determining the network access permitted the class, determining the network services provided to the class and finally assigning the secondary password to a device (12') seeking to communicate within the network (100).
Abstract:
A processor system (100) provides electrical power and processing to a plurality of appliances. A data bus (32) receives a control input signal from each of the plurality of appliances (36) and transfers electrical power (31) and output command signals (44) to each of the plurality of appliances (36). A processor (34), coupled to the data bus (32), generates an output command signal (44) for each of the plurality of appliances (36) in response to the input control signals (42).
Abstract:
The present invention provides a user with the option of editing handwritten input (100) such that user may elect to join or combine one or more discrete continuous segments (S1, S2, S3), or blocks of ink, to form a single discrete continuous segment. The joined segments are then presented as a single discrete segment and analyzed as a single discrete segment by the method of machine recognition of handwritten input being employed by a device that functions to receive handwritten input.
