Filed:

Apr 14, 2000

Appl. No.:

09/549752

Inventors:

Barton L. Guthrie - Birmingham AL
Robert A. Daniels - Haverhill MA

Assignee:

Sherwood Services AG - Shaffhausen

International Classification:

A61B 500

US Classification:

600587

Abstract:

This invention relates to a three-dimensional digitizer and a probe means associated with said digitizer that enables a virtual target point to be visualized and depth and range measurements to that target to be determined. In one embodiment, a mechanical articulated arm or other type of 3-D digitizer is used in conjunction with a graphics workstation which displays images from CT, MR, or other scanning means of the anatomy. By registration of the digitizer to the patients physical anatomy, a representation of the digitizer on the display means of the graphics workstation is possible. The position of the digitizer will be displayed in its quantitative relationship to the patients anatomy, including internal pathologies such as tumors. The end means of the 3-D digitizer could be a holder or fixation device which can accept a sliding probe. The probe, for example, could be a shaft which slides in a spring-loaded or non-spring-loaded fashion within the fixation means of the digitizer.

International Classification:

A61B 1900

US Classification:

606130

Abstract:

This invention relates to apparatus for calibrating and recalibrating a digitized navigator or so-called frameless stereotactic instrument or device during a surgical operation. The apparatus enables calibration for the stereotactic digitizer to be recovered after sterile draping of the patient, movement of the patient's head during operation, relative movement of the patient's head and reference apparatus associated with the stereotactic digitizer, power failures, or other events which could compromise calibration of the stereotactic digitizer during the operation which would otherwise preclude continuations using the digitizer. It also provides convenient means for initial calibration or repeat calibration, should that be necessary. The apparatus is, in one embodiment, cooperatively coupled to, or coupled so as to move with, the portion of the patient's body which is being operated upon and enables the repositioning of the recalibration means after sterile draping. In exemplary embodiments, the apparatus would include a reference point structure or a reference holding structure that can be attached to, for example, a surgical head clamp in a neurosurgical operation and can be accessed for calibration positioning or calibration locationing by the digitizer during the operation.

Abstract:

A method of wireless communication includes receiving a plurality of parameter values at a user equipment (UE) using a first local oscillator (LO) frequency value, where the plurality of parameter values includes indications of a downlink frequency channel and an uplink frequency channel. The method further includes determining a second LO frequency value at the UE, where the second LO frequency value is determined using the indications of downlink and uplink frequency channels. The method further includes receiving downlink signals from an associated base station using the second LO frequency value.

International Classification:

H04W 16/10

Abstract:

Methods and systems for channel mapping in a densely deployed network are disclosed. The system includes a node comprising a plurality of base stations configured to communicate with client devices in a wireless communication network, wherein transmission from the base stations to the client devices is conducted on a downlink (DL) frequency band and transmission from the client devices to the base stations is conducted on an uplink (UL) frequency band. The DL frequency band is different from the UL frequency band. DL and UL frequency pairs for the base stations are assigned according to a channel mapping scheme that determines DL and UL frequency pairs based on a plurality of channel parameters. The channel parameters include, for example, received signal strength indicator (RSSI), signal to noise (S/N) ratio, channel capacity, and bit error rate (BER).
