Abstract: A microprocessor external instruction feature which provides for a single chip microprocessor with on-chip read only instruction store (ROS) that can also be operated with an off-chip instruction store. To accomplish this, the microprocessor instruction sequencing logic (instruction store 10, instruction register 36, instruction counter 38, and sequencing logic 40) is duplicated off-chip by external instruction store 60, instruction register 64, instruction counter 62 and sequency logic 66. The address in counter 62 is generated off-chip and is not transferred from counter 38. An XI MODE input pin signal causes the microprocessor to take its instructions from the external instruction store via 12 XI input pins instead of from the on-chip ROS. A BR DECISION output pin signal from the microprocessor, which indicates that the branch conditions have been met, causes the external instruction counter 62 to be loaded with a branch address from the external instruction register 64 instead of being stepped by external sequencing logic 66. A WAIT output pin signal causes the external instruction feature logic to suspend operations while the microprocessor is in its wait state.

Abstract: A two degree-of-freedom, free-rotor, gas-bearing gyroscope having greatly reduced sensitivity to acceleration-induced and other disturbances. An electromagnetic forcer (42) acts on the rotor (22) to keep the axial component of bearing deflection negligible. Closed-loop control circuitry for energizing the axial forcer responds to a linear displacement signal. The circuitry also provides an output signal proportional to the component of acceleration along the spin axis. This signal may be used to replace an accelerometer output signal in navigation equipment. In addition to being functional during normal operation, the control functions during start-up and shut-down to center the rotor over the support ball (16). The functions of forcer and torquer are combined in a single structure. A dual motor arrangement (32, 34, 36, 38, 40) and a dual forcer-torquer arrangement provide cancellation of bias variations due to housing, shaft, and bearing deflections. The ball support shaft (18) has larger diameter and the gas fill pressure is lower than would be feasible in the absence of the electromagnetic axial forcing.

Abstract: A circuit for generating a percussion envelope for use in electronic organs and similar electronic keyboard instruments wherein the envelope has an attack overshoot, a long decay, and a snub decay when the key is released. A velocity sensing feature (74) is included, wherebythe force with which the key is struck determines the amount of capacitor discharge, and the voltage remaining on the capacitor (82) is compared with the amplitude of the attack portion of the envelope in a first comparator (130) such that decay is initiated when a compare condition is reached. A second comparator (138) sets the amplitude at which the envelope undergoes transition from a fast decay to the normal long decay. The timing for the attack and three decay portions of the envelope are independently controlled by means of four clock driven electronic gate circuits (50,52,56,60) which incrementally charge and discharge the main timing capacitor (62). The gate circuits (50,52,56,60) include a pair of serially connected field effect transistors (92,94) having a capacitor (98) connected attheir juncture. Thetiming control for each individual keyer, including all of the timing capacitors, is contained within a separate LSI chip (101).

Abstract: A matrix switching system has N inputs and M outputs and three stages (F, M, L) of matrices. The first stage (F) includes n substage matrices (10a...10q), each with x inputs (16a...16q) and x outputs (18a...18q) where N equals nx. The second stage (M) provides x substage matrices (12a...12p) each with n inputs (20a...20p) and m outputs (22a...22p), an output (18a...18q) from each first substage matrix (10a...10q) being connected to an input (20a...20p) of each second stage matrix (12a...12p). A third stage (L) employs m substage matrices (14a...14q) each with x inputs (24a...24q) and x outputs (26a...26q) where M = mx, an output (22a...22p) from each second stage (M) being connected to an input (24a...24q) of each third substage matrix (14a...14q). Switching means are provided at each node of each substage matrix. Means are provided for choosing a proper sequence of switches to reach a selected output to be connected to a selected input.

Such an arrangement in the middle stage of the three stage matrix, known as a midstage link (21), allows conditionally non-blocked re-routing in situations where a substage appears to be blocked.

Le gradient Gy est alors annule et le sens du gradient Gx est ensuite inverse de maniere repetee. Pendant l'action d'inversion du gradient Gx, un petit gradient Gz est obtenu. Chaque gradient Gx inverse est maintenu constant pendant une periode de temps suffisante pour generer un signal de decadence d'induction libre produisant ainsi un echo multiple des spins dans le plan selectionne. Des signaux alternes sont inverses dans le temps et a la fois les signaux inverses dans le temps et non inverses dans le temps sont soumis a une transformation de Fourier.
