Title: Adaptive tuning device and method for a wireless communication device
Inventor: CAMPBELL COLIN K
IPC: H03H9/25
Filed: 2001-05-30
Abstract: An adaptive tuning method for a wireless communication device determines the impedance of a matching circuit relative to an impedance to be matched and adjusts the impedance of the matching circuit accordingly. A passive surface acoustic wave (SAW) device includes multiple terminated interdigital transducers (IDTs) which generate reflected SAWs when excited by incident SAWs, each reflected SAW having magnitude and phase characteristics dependent upon the particular IDT termination. According to the invention, the IDT terminations include the impedance matching circuit and the impedance to be matched. Input IDTs in the SAW device are excited with electrical signals, which are converted to generate the incident SAWs. The resultant reflected SAWs are converted by output IDTs into output electrical signal signals which can then be analyzed to determine magnitude and phase differences between the output electrical signal signals and generate an impedance matching circuit control signal based thereon.

Inventor: ARENBERG IRVING K
IPC: A61K9/22
Filed: 1999-12-03
Abstract: The present invention provides methods and devices for controlled delivery of a therapeutic agent to an internal cavity of the ear, particularly to the inner ear. In general, the invention uses a drug delivery unit for inner ear treatment which employs a portion of carrier media material containing one or more therapeutic agents therein. The carrier media material is designed to release the therapeutic agents in a controlled manner over time. The drug delivery unit is shaped and sized for placement of at least a portion thereof in the round window niche of a patient. The released therapeutic agents come in contact with the round window membrane and pass therethrough into the inner ear for treatment purposes. This system provides many benefits ranging from the ability to deliver drugs in a site specific, highly controlled manner to the transfer of such materials with minimal patient discomfort and monitoring requirements.

Patent CA-2378166-A1 (CA)
Title: Optical noninvasive blood pressure sensor and method
Inventor: OLSON WILLIAM
IPC: A61B5/022
Filed: 2001-05-10
Abstract: A blood pressure sensor (12) includes a source of photo-radiation, such as an array (30) of laser diodes (30A-I). The sensor also includes a two-dimensional, flexible reflective surface (14).  The reflective surface is nominally positioned relative to the radiation source such that the radiation travels in a direction normal to the reflective surface. The reflective surface is placed adjacent to the location on the patient where the blood pressure data is to be acquired. Radiation from the source is reflected off of the reflective surface onto a two-dimensional array (17) of photo-detectors (18).  Systolic and diastolic blood pressure fluctuations in the patient are translated into deflections of the patient's skin. These deflections cause corresponding deflections in the two dimensional reflective surface. The associated movement of said flexible reflective surface (14) due to blood pulsation causes scattering patterns from said reflective surface to be detected by the two dimensional array (17) of photo-detectors (18). The output from the array of photo-detectors is calibrated to blood pressure in mmHg during a calibration procedure to obtain a set of calibration relationships for one or more of the individual detectors. The calibration relationships are then used during acquisition of blood pressure data to arrive at blood pressure data.
