09/505274

Inventors:

Mark Daniel Dvorak - Waseca MN
Paul Eugene Bauhahn - Fridley MN

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

H03B 2900

US Classification:

331 78, 331 46, 331 47, 708250, 708251

Abstract:

Random pulse generators and generating systems using at least three oscillators. The output signals of at least two of the oscillators are combined to disturb the output signal of a final oscillator. For one configuration, combined output signals of at least two phase shift oscillators are used to modify the feedback signal of a final phase shift oscillator, thus disturbing the output signal of the final oscillator. For another configuration, the output signals of at least two phase shift oscillators are used to drive a subtractor whose output signal is combined with the output signal of a final phase shift oscillator to drive a subsequent subtractor, thus disturbing the output signal of the final oscillator.

Mark D. Dvorak - Waseca MN, US

Assignee:

Honeywell International, Inc. - Morristown NY

International Classification:

H03B027/00

US Classification:

331 49, 331 46, 331179, 331117 FE, 331 74

Abstract:

A single integrated chip has first and second voltage controlled oscillators and first and second buffers. The first voltage controlled oscillator has a first output defined by a first frequency band, and the second voltage controlled oscillator has a second output defined by a second frequency band. The first and second buffers selectively couple the first and second outputs to a common output. The first buffer is coupled between the first frequency controlled oscillator and the common output, and the second buffer is coupled between the second frequency controlled oscillator and the common output. The first buffer has a high output impedance when the second buffer couples the second output to the common output, and the second buffer has a high output impedance when the first buffer couples the first output to the common output.

Mark D. Dvorak - Waseca MN, US

Assignee:

Honeywell International, Inc. - Minneapolis MN

International Classification:

H03F 1/14

US Classification:

330 51, 330 9, 330122, 330255, 330310, 330311

Abstract:

An operational amplifier with selectable performance characteristics is provided. The operational amplifier provides a sleep mode (e. g. , fully disabled) in addition to providing a number of different levels of awake operation (e. g. , different performance characteristics). As such, the op-amp can allow a system to use only the power needed to obtain a required level of performance at any point in time. For example, the op-amp may be operated at a minimum power mode, an awake at mid-level power mode, or an awake at maximum power mode.

Appl. No.:

10/191173

Inventors:

Mark D. Dvorak - Waseca MN, US

Assignee:

Honeywell International, Inc. - Morristown NJ

International Classification:

H03K 5/22

US Classification:

327 66, 327 65, 327560, 330257, 330261

Abstract:

An operational amplifier has a bias circuit, a differential amplifier, an output stage, and a feed forward circuit. The bias circuit provides a reference. The differential amplifier is coupled to a pair of input terminals and provides a differential output based on the first and second inputs. The output stage responds to the reference and to the differential output so as to supply a current to an output terminal. The feed forward circuit responds to the differential output in order to increase and decrease current to the output terminal. As a result, the feed forward circuit extends the dynamic range of the operational amplifier.

Assignee:

Honeywell International, Inc. - Morristown NJ

International Classification:

H03L 7/06

US Classification:

327157, 327108

Abstract:

A differential charge pump with common mode and active regulators is presented. Either type of regulator may be used to improve the performance characteristics of the differential charge pump. The active regulator increases the output range of the differential amplifier. The common mode regulator establishes the common mode voltage of the differential charge pump. The common mode voltage is established independently from external circuitry and does not use a feedback path. The common mode regulator may also be used to establish a mid-rail voltage, which may be used to further improve the output range of the differential amplifier.

US Classification:

370492

Abstract:

A bandwidth management system for a remote repeater network for modifying a first signal to create a second signal within the bandwidth of a communications link, transferring the second signal across the communications link, and reconstructing the first signal at the remote end of the communications link. The bandwidth management system featuring several mixing modes for performing the signal conversion and reconstruction. The system offering a calibration feature to correct for phase distortions introduced in reconstruction of the original signal. The calibration feature incorporating signals from a global positioning satellite system for reconstruction.

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

G01S 302

US Classification:

342457

Abstract:

Multiple pulses of narrow band signals of varying frequency are detected by multiple spaced apart receivers such that average time difference of arrivals of the signals from an item to be located are determined. The average time differences are used to calculate a position of the item to be located with a desired accuracy, such as within one meter in one embodiment. One of multiple receivers or rangers initiates a location process by transmitting a sync pulse. The sync pulse is received by a scout and other rangers. The scout is a small robot which acts as a transponder, sending out its own narrow band return pulse in response to the sync pulse. Each ranger then determines a difference in time between the sync pulse it receives and the return pulse generated by the scout. The location process is then repeated again at different selected narrow band frequencies, and an average of the difference in time at each ranger is determined. Each ranger is networked together via a standard wireless network, and also obtains position information via standard GPS methods.
