US Patent:

49927272, Feb 12, 1991

Filed:

Jun 28, 1989

Appl. No.:

7/373123

Inventors:

Richard D. Simpson - Houston TX
Iain C. Robertson - Bedford, GB2

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

G01R 3128

US Classification:

324158R

Abstract:

A digital data storage circuit for a digital signal processor which is capable of receiving asynchronous inputs and is such as to be testable by selectively configuring the storage circuits as a shift register enabling the entry and extraction of test data in the processor. The storage circuit includes two latch elements each formed by two complementary transistor inverter circuits connected in a positive feedback arrangement and in which the output current capability of the second inverter circuit is restricted to enable the latch element to change state in response to input signals applied to it. Asynchronous inputs are applied to a first latch element through switch means comprising a complementary transistor inverter responsive to a SET input in series with a transistor responsive to a CLEAR input. The complementary inverter is connected to the input of the first latch element through a series connected transistor. During testing the series connected transistor is blocked and the first latch element is connected in a two elements per bit shift register configuration with the second latch element by series connected transistors controlled by antiphase square waves.

International Classification:

G01R 2726

US Classification:

324 61R

Abstract:

A steam quality monitor monitoring the quality of steam flowing in the pipe includes capacitance sensing apparatus which senses the capacitance of the flowing steam and provides a capacitance signal corresponding to the said capacitance. Another sensor which may be either a temperature sensor or a pressure sensor senses either the temperature or pressure of the steam and provides a representative type signal. Circuitry connected to the capacitance sensor and to the temperature or pressure sensor provides an output corresponding to the quality of steam in accordance with the capacitance and the temperature or pressure signal.

International Classification:

G01V 318
G01V 330

US Classification:

324338

Abstract:

The present invention is a well logging method for determining the water saturation of an earth formation and the water's resistivity. Electromagnetic energy is transmitted into the earthen formation from a borehole traversing the earth formation. The electromagnetic energy is transmitted at two different frequencies within a range of frequency from 10 MHz to 200 MHz. Electromagnetic energies are received in the borehole from the earth formation. A phase difference and amplitude ratio for each transmitting frequency is derived from the received electromagnetic energy. The water resistivity and water saturation of the earth formation are derived from the derived phase differences and the amplitude ratios.

International Classification:

G08B 2100

US Classification:

340672

Abstract:

A magnet and two magnetic sensing means are spatially related to each other, with each magnetic sensor sensing the relative movement between the magnet and the magnetic sensor. The magnetic sensor provides a signal corresponding to the relative movement. Circuitry connected to both magnetic sensors provides an alarm in accordance with the signals from both magnetic sensors when the rotation of the crank arm is in one direction and does not provide an alarm when the rotation of the crank arm is in the opposite direction.

International Classification:

H03K 906
H03K 522

US Classification:

307518

Abstract:

A digital integrated circuit normally operated from an external clock signal and including an internal reference oscillator for providing a reference signal as an internally generated signal backup in the event that the external clock signal is not present or is too low in frequency for safe operation of the integrated circuit. The integrated circuit has a frequency comparator for receiving the external clock signal and the internal reference signal as inputs and producing an output indicative of the state of the external clock signal. A two-way switch is connected to the output of the frequency comparator and selects either the external clock signal or the internal reference signal for transmission to the integrated circuit based upon the output from the frequency comparator. The frequency comparator includes a frequency discriminator which has two parts for providing respective complementary output logic signals when the external clock signal is consistently at either the high logic level or the low logic level, and for respectively providing the same output logic signal when the external clock signal alternates between the high and low logic levels. An output circuit is connected to the outputs of the first and second parts of the frequency discriminator for combining the output signals of the first and second parts in producing the output of the frequency comparator as provided to the two-way switch.

International Classification:

G06F 1300

US Classification:

364200

Abstract:

A system for real-time digital signal processing employs a single-chip microcomputer device having separate on-chip program and data memory, with separate address and data paths for program and data. An external program address bus allows off-chip program fitch in an expansion mode, with the opcode returned by an external data bus. A bus interchange module allows transfer between the separate internal program and data busses in special circumstances. The internal busses are 16-bit, while the ALU and accumulator are 32-bit. A multiplier circuit produces a single state 16. times. 16 multiply function separate from the ALU, 32-bit output to the ALU. One input to the ALU passes through a 0-to-15 bit shifter with sign extension. The on-chip program memory may be a RAM and this additional RAM may be configured as either program or data memory space. The processor may operate with all off-chip program memory and a large on-chip data memory, or with program execution from on-chip RAM (downloaded from off-chip program memory) using a block move instruction.

US Classification:

307351

Abstract:

An overvoltage detector circuit for connection to an input terminal of a microcomputer device or the like employs a bistable latch with two inputs, one connected to a reference potential and the other to the input terminal. When the inputs are gated, the latch flips to one state if the terminal is at an overvoltage, or the other state if the terminal is at zero or logic-1. This circuit may be used to institute a test mode for the microcomputer.

US Classification:

Abstract:

A system for real-time digital processing employs a single-chip microcomputer device having a high-speed on-chip program ROM and a separate data RAM, with separate address and data paths for program and data. An external program address bus allows off-chip program fetch in an expansion mode, with the opcode returned by an external data bus. A bus interchange module allows transfer between the separate internal program and data busses in special circumstances. The internal busses are 16-bit, while the ALU and accumulator are 32-bit. A multiplier circuit produces a single state 16. times. 16 multiply function separate from the ALU, with 32-bit output to the ALU. One input to the ALU passes through a 0-to-15 bit shifter with sign extension. The on-chip program ROM has a low-level precharge circuit with feedback to improve speed or access time.
