Title: Error detection in microprocessor systems - by executing error routine during access period of macro-programmed memory
Inventor: ILLI DIETRICH DR ING
IPC: G06F11/267
Filed: 1978-12-20
Abstract: An error detector routine for microprocessor systems operates during the accessing period required for macro-instructions and so does not slow down the operation of the system. The central processor is controlled by a micro programme store for executing all internal control signal generations. User data is entered from a separate memory over a register and multiplexer. Macro-instructions, such as jump operations, are held in a programme store coupled over a register and first-in-first out memory. During the access period of the macro store, an error checking operation is performed. Test data held in a register is delivered and transmitted to mask register. The generated data is multiplexed into a second register and is compared with the output to indicate any error.

Title: Tactile flight control for glider - has transducer strips up at each side of control stick with vibration providing sensory feedback
Inventor: HORBRUEGGER HERBERT
IPC: B64C13/04
Filed: 1978-12-30
Abstract: A tactile flight control has two transducer strips along the handgrip of the control stick which give tactile information related to the dynamic situation of the aircraft. In a glider the relevant information can be rate of climb or descent as well as airspeed. The transducers are linked to a control motor which provides the variable frequency and amplitude vibration, controlled from the flight instrumentation. The pilot does not have to look at the instruments to determine the aircraft attitude and can devote all his attention to flying. The tactile controls provide a rapid response and are monitored correctly even with poor visibility and in a noisy cockpit.
