Abstract: In an electronic package, a solder connection (14) for bonding faying surfaces (31, 40) is formed of tin-bismuth alloy comprising a tertiary metal, preferably gold or silver, in an amount effective to increase the melting temperature of the alloy and enhance mechanical properties of the connection at elevated temperatures typically encountered during operation. A process for forming the solder connection comprises applying a film (36) of the tertiary metal onto at least one faying surface (31) and thereafter applying tin-bismuth solder paste (38) onto the film. Preferably, a plate (26) of tin-bismuth alloy is first electroplated onto the faying surface (31), onto which the tertiary metal is plated. During heating to reflow the solder, the tertiary metal dissolves to produce a uniform liquid that forms the connection.

Abstract: An encryption code and at least one key are provided to a secure transmission device, via an external keying device (100) and stored in a first volatile memory (102). An encrypted representation of the at least one key, based on the encryption code and the at least one key, is generated and stored in a non-volatile memory (103). Upon power down of the secure transmission device, the encryption code is stored in a second volatile memory (106) and the at least one key and encryption code stored in the first volatile memory (102) are erased.

Abstract: A code division multiple access (CDMA) communication system (10) for reuse of available spreading codes includes a first communication device (100) and a second communication device (106). The first and second communication devices (100, 106) are capable of identifying spreading codes and operating frequencies that are optimum for their respective radios. The identity of the optimum spreading code and the frequency of the optimum frequency is communicated from one communication device (100) to another (106), hence allowing the two devices to communicate with each other using their respective optimum codes and frequencies. These codes and frequencies may be periodically updated to provide reusability of codes. By dynamically updating codes and frequencies without the use of a central station, the efficiency and reusability of codes in the CDMA system (10) is significantly enhanced.

Abstract: A packet transmission system (100) for reducing request traffic contention and the likelihood of resource misallocation includes a communications controller (110) and a plurality of remote requesting units (112) requesting packet transmission services. In response to receipt of a request (302), the controller (110) transmits a grant (306) to a requesting unit (112) when packet transmission resources (304 and 310) are available or a request acknowledgment (306) when packet transmission resources (304 and 310) are unavailable. Each remote unit (112) comprises apparatus structure and method steps for transmitting requests (302) to the controller (110) and starting a first timer having an interval (T) determined as a function of a number (Q) of outstanding requests (302). Upon receipt of an acknowledgment (306), the remote unit (112) starts a second timer having an interval (T1) longer than the inverval (T). Upon expiration of either the first timer or the second timer, the remote unit (112) will then and only then transmit a duplicate request (302). By limiting the number of duplicate requests transmitted by a remote unit (112), the present invention operates to reduce request traffic contention and the likelihood of resource misallocation.

Abstract: An apparatus is provided for use in a multi-channel digital transmitter and receiver. A filtering process is accomplished by conditioning portions of a digitized signal during digital signal processing by integrating, taking the difference of, and multiplying portions of the digitized signal. The filtering process may be used in conjunction with a receiving process to generate a digitized channel signal (166, 168, 170, 172) by conditioning (132, 134, 136, 138) the digitized signal (128) and subsequently Fourier transforming (148) the conditioned portions of the digitized signal. Alternatively, the filtering process may be used in conjunction with a transmitting process by inverse Fourier transforming (324) a plurality of digitized information signals (300, 302, 304, 306) to be transmitted, generating a composite digitized signal (352), and subsequently conditioning the composite digitized signal (358).

Abstract: An error detector circuit (300), and an associated method, is disclosed for a discrete receiver, the error detector circuit (300) indicates bad frames of binary information signals which contain distorted bits of data in numbers so great as to prevent a convolutional decoder (312) from generating, accurately, a decoded signal. When bit errors are detected in numbers beyond a first preselected value of signal quality of a received signal combined with the detected number of bits errors forming a signal beyond a second preselected value, a bad frame is detected.
