US Patent:

6380810, Apr 30, 2002

Filed:

Aug 24, 2000

Appl. No.:

09/645212

Inventors:

Brian P. Sutton - West Linn OR

Assignee:

Tektronix, Inc. - Beaverton OR

International Classification:

H03L 7093

US Classification:

331 17, 331177 R, 331175, 331 25

Abstract:

A reduced lock time phase locked loop has a speed up circuit with an operational amplifier to amplify a differential voltage across a filter resistor of an RC noise filter, the RC noise filter coupling a coarse tune voltage to a VCO. The amplifed differential voltage is applied to the bases of a pair of opposite polarity transistors, the emitters of the transistors being coupled to a filter capacitor in the RC noise filter for rapid charging/discharging. Alternatively the amplified differential voltage is applied to a pair of parallel, opposite polarity diodes coupled to the filter capacitor for rapid charging/discharging.

Inventors:

Brian P. Sutton - West Linn OR, US

Assignee:

Tektronix, Inc. - Beaverton OR

International Classification:

H03L 7/00
H03L 7/099

US Classification:

331 10, 331 11, 331 25

Abstract:

A low phase noise YIG oscillator based phase locked loop couples an output frequency to a delay line discriminator to provide a phase noise feedback signal to a wideband tuning port of the YIG oscillator. A delay line in the delay line oscillator may be implemented with either a resonant circuit or a bandpass filter of sufficient bandwidth so that the output frequency and phase noise sidebands are not attenuated. The resonant circuit may be implemented as a YIG sphere integrated into the YIG oscillator in the same magnetic path as the YIG sphere in the oscillator circuitry.

Abstract:

The invention relates to methods by which radio signals can be transmitted to, and received by, a radio receiver such that the receiver consumes very little power from a battery or energy source. The invention also relates to methods by which radio signals, modulated with data information, can be produced by a transmitter that consumes very little power. The invention is applicable not only to medical implants, but any application requiring a radio receiver to operate with very low power consumption.

Appl. No.:

11/668492

Inventors:

Brian P. Sutton - West Linn OR, US

International Classification:

A61N 1/00

US Classification:

607 4, 607 60

Abstract:

The invention relates to an implantable medical device having a telemetry circuit for bidirectional data communication between the implantable medical device and an external device, wherein said telemetry circuit comprises a transceiver unit that is electronically switchable between a fully-synthesized frequency agile transceiver configuration and a low power single channel configuration, wherein the transceiver unit consumes less power when operated in its low power single channel configuration than in its fully-synthesized frequency agile configuration.

International Classification:

A61N 1/372
H04W 52/02

Abstract:

A method for waking up an implantable medical device from a dormant state, an implantable medical device, and a system that includes such an implantable medical device and an external device. The implantable medical device is woken up from a dormant state by sending a modulated wakeup signal via a wireless link from an external device. The modulated wakeup signal is demodulated by way of a demodulator circuitry of the implantable medical device so as to produce a demodulated wakeup signal. The demodulator circuitry is permanently ready for operation. An awake state of the implantable medical device is then activated in response to the demodulated wakeup signal.

Abstract:

A lead has at least a first and a second conductor. The first conductor and the second conductor each have an electrically conducting core that is surrounded by an electrical insulator. The electrical insulator of the first conductor if formed from a first material, and the electrical insulator of the second conductor is formed from a second material. The first material differs from the second material.
