  • Patent number: 4338597
    Abstract: A data processing system remote monitor interface includes a first device which transmits different types of time-related information signals along multiple parallel channels to a second device for reception and combination into a different number of information signal outputs. The different types of digital information signals are synchronized by the first device prior to transmission to the second device. Components in the first device, the multiple parallel channels, and the second device are selected to maintain signal synchronization by minimizing signal skew thereby eliminating the necessity for signal resynchronization in the second device. The second device includes a receiver section which has a plurality of receivers. Each receiver operates to receive only one digital information signal and to pass the received signal onto its output.

  • Patent number: 4337497
    Abstract: Device for detecting the direction and change of rotational speed of a rotating element. In one embodiment, a pair of phototransistors which are energized by a light source according to an ordered sequence through a disk formed by opaque and transparent sectors coupled to the rotating element. The two phototransistors controls, when energized the switching on of two transistors which enable the discharge of two capacitors, charging with a predetermined time constant in the interval time between discharges. The discharge control action of one of the two phototransistors on a first capacitance is however conditioned by the charge level reached by the other capacitance and therefore both by the order in which phototransistors are energized and by the energization frequency. If the energization frequency is lower than a certain limit or the energization order is not the correct one, the first capacitor reaches a charge level higher than a reference value and supplies an indication signal accordingly.

  • Patent number: 4334307
    Abstract: A data processing system employing firmware for executing a self test routine each time the system goes through the power-up cycle. The self test firmware provides for compilation of a system configuration map during each execution so that configuration and status data is made available for accessing by the system operation firmware and application software. This enables external systems to set appropriate interrupt vectors and levels and to arrange their physical I/O and device handlers so that various devices within the local system can be accessed. The routines performed in the self test operation include a CPU test, a RAM test, a real time clock test, a communication controller loop-back test, a ROM signature calculation, a controller I/O test, a system configuration map compilation, and a status display routine.

  • Patent number: 4332624
    Abstract: Exposed surfaces of a layer of a copper thick film paste on a multilayer substrate are cleaned after being fired so that such surfaces are readily solderable to the extent that conventional tin/lead solders will wet said surfaces. The substrate with the exposed surfaces of a layer of a fired copper thick film paste is cleaned by being immersed in a warm dilute solution of an acid containing a fluoride ion, such as HF or HBF.sub.4 for a short period of time. After the short period of time of immersion has elapsed, the substrate is removed from the dilute acid solution and rinsed to remove substantially all traces of the cleaning solution.

  • Patent number: 4325117
    Abstract: Information from a document is read by a reader sorter; the information is organized in fields including a transit field which is made up of 8 decimal digits and a check digit. The 8 decimal digits are each multiplied by a predetermined number which depends on the position of the decimal digit in the transit field as indicated by a position counter. Signals indicative of the decimal digit and the position in the transit field are applied to the address terminals of a Programmable Read Only Memory (PROM). Each address location stores the units position of the product of the multiplication of the decimal digit times the predetermined value. A firmware routine stored in a control memory performs the check digit calculation "on the fly" using the units position of the product from the PROM and certain status bits stored in a scratchpad memory.
