Abstract: Optimum routing for communications between a central control unit (CCU) and remote units (nodes), such as electricity meters, distributed on an electrical power line is established by broadcasting from the CCU an interrogation signal to be received by the remote units. In response to a receipt of the interrogation signal, each remote unit returns an acknowledgement signal, time multiplexed with the acknowledgement signals of the other remote units, to the CCU which determines which units, if any, are "mute", i.e., have not acknowledged. The CCU then selects remote units in proximity to the mute remote units if it has already a good knowledge of the network or at random otherwise, to function as relays and repeats interrogation of the remote units via the relays. This process is repeated, if necessary, until communication paths between the CCU and all remote units are established directly or via relay units, to form maps. Numerous maps developed for the nodes during various time periods having different power line interference characteristics are stored in a data base to be accessed by the CCU to quickly establish an optimum route during subsequent periods having similar line interference characteristics.

Abstract: Method and apparatus are provided for developing a digital timing signal indicative of when a head of a helical scan recorder (30) is positioned over a recorded stripe on magnetic tape (32). The method involves rotating a drum (36) upon which a head is mounted while the magnetic tape (32) is transported past the drum at a speed greater than the nominal speed at which stripes were recorded on the tape. Given the geometry of the system and format of the tape, the head is eventually able to recognize a pattern of digital data. The timing of the recognition of the pattern of digital data is used to determine the precise time, relative to each rotation of the drum (36), that the head ceases to traverse a stripe and the precise time during each rotation of the drum that the head begins to traverse a stripe. The determination of the edges of the digital timing signal is repeated upon every rotation of the drum (36). A servo timing signal for a servo head (also mounted on the drum) is generated in ninty (90) degree phase relationship to the digital timing signal.

Abstract: A cryptographic system creates a key table from a single key such that the relationship between the keys in the key table cannot be determined even if the system implementation is known. The system uses variable functions in which the determinants are changed by the variable function chosen by the determinant. Thus, the functions used in creating the key table do not have to be one-to-one functions. From the key table, four blocks of bytes of additional key based determinants are formed which are called masks. The original key does not exist in either the key table or the mask table. The system preferably uses the key table in a multiple round encryption process. The keys chosen from the table for a key addition operation are a function of the plaintext, the current state of the ciphertext, and the mask values. Therefore, the order in which the keys are chosen is not predetermined or patterned. The system also selects the other encryption functions, including permutations and substitutions, by the plaintext, current state of the ciphertext and the mask values. The cryptographic system also can include a function referred to as the enclave function. This function operates on lookup tables and creates complete inter-symbol dependency on the block of bytes.

Abstract: An angle of rotation detector has a drive unit which supplies 90 degree phase shifted signals to a pair of stator coils and measures an analog output from a rotor coil in a resolver. A calculating device calculates the rotational angle of the resolver using the output of an analog to digital converter receiving the analog output of the rotor. In one embodiment, the calculating device performs a Fourier transform to compute the phase of a fixed frequency component contained in the output of the rotor coil. In another embodiment, the drive unit supplies signals wherein f(T/2 + t) =-f(t) and the calculating device performs a Fourier transform using data from successive half periods of the drive waveform. In another embodiment, the output of the rotor is sampled at 1/4 period of an excitation signal from the drive unit and the calculating device determines the phase difference between the excitation signal and the rotor output. In still another embodiment, the calculating device compares the outputs at two or more points having a fixed time relationship and compares the result to stored reference data to arrive at the angle of rotation. <IMAGE>

Abstract: An error handling facility is disclosed which includes a central processing unit (CPU) incorporating a basic processing unit (BPU) including a pipelined AX unit (as well as a decimal numeric - DN - unit and a floating point - FP - unit) having a plurality of software visible registers and which issues an AX ERROR signal in response, among others, to sensed errors occurring within the AX unit during the processing and execution of instructions. An auxiliary (XRAM) memory receives, via a cache unit, and temporarily stores a record of the contents of the software visible registers concurrently with the availability of the result of each instruction executed by the AX unit. A clock unit is coupled to receive the AX ERROR signal and responds by suspending clock signals to the BPU as well as notifying a service processor (SP) of the error occurrence. The relevant contents of the XRAM are also forwarded to the SP for analysis, and the SP can order a restart by issuing a "resume" signal to the clock unit after the information obtained from the XRAM has been analyzed and the failing CPU reinitialised as necessary. The issuance of an AX ERROR occurring in the pipeline activity signal is delayed until all instructions in the pipe ahead of the faulting instruction have completed execution. Alternatively, the delay can be extended until all instructions in the pipe ahead of and including the faulting instruction have completed execution. <IMAGE>
