An implantable stimulation system comprises a stimulator (138) for generating electrical stimulation and a conductive stimulation lead (134) having a proximal end electrically coupled to the stimulator (138), wherein at least a first component of the impedance looking into the stimulator (138) is substantially matched to the impedance of the stimulation lead (134). At least one distal stimulation electrode (132) is positioned proximate the distal end of the stimulation lead (134).

Landmines are affecting the lives and livelihoods of millions of people around the world. A number of detection techniques, developed for use with impulse ground penetrating radar, are described, with emphasis on a Kalman filter based approach. Comparison of results from real data show that the Kalman filter algorithm provides the best detection performance, although its computational burden is also the highest.

A stimulation lead is configured to be implanted into a patient's body and includes at least one distal stimulation electrode and at least one conductive filer electrically coupled to the distal stimulation electrode. A jacket is provided for housing the conductive filer and providing a path distributed along at least a portion of the length of the lead for conducting induced RF energy from the filer to the patient's body.

A system that integrates Global System for Mobile Communications (GSM) and Wireless Fidelity (WiFi) wireless local area network (WLAN) services is provided. The system couples among components of a communications service provider and a provider of WiFi services to provide integrated cellular communications and wireless fidelity network services to users of mobile devices. The system monitors communications between the service provider and the mobile devices and automatically gathers identification information of the mobile devices. Upon authentication of the mobile devices via an exchange of information among the service provider infrastructures and the mobile devices, the system controls access of the mobile communication devices to WiFi services via the service provider infrastructure using the identification information.

Integrating GSM and WiFi service in mobile communication devices

A probe instrument using room-temperature sensor(s) that can measure magnetic susceptibilities variations. The instrument includes room temperature magnetic sensors, and detects the sample, that is the tissue response to an applied field coil. The sensors that can be used include magnetoresistive, fluxgate and magnetoinductive sensors. The applied field coil dimensions are chosen so that the applied field is optimized for maximum response from the item of interest while minimizing the effects due to the overlying tissue and at the same time not unduly increasing the sensitivity of the instrument to adjacent organs. To minimize noise introduced in the sensor due to fluctuations in the applied field, the applied field is canceled at the position of the sensor. To overcome variations in the sensor output due to fluctuations in the applied field, change in the ambient temperature and mechanical relaxation of the instrument, the detector assembly is oscillated while the examined patient remains stationary.

Ferromagnetic foreign body detection using magnetics

An object detection portal wherein a video image is obtained of a volume or area being scanned, and location of a threat object is determined and displayed in real time as an indicator overlay on the video image. An individual subject being scanned may be continuously monitored by an operator during an object divesting process, and an operator may view the threat object moving from or remaining with the subject. Object location information is supplied to a video driver to superimpose the overlay on a real time image of a subject. The scanning portal may interact with an exit barrier. The exit barrier may be activated automatically in response to sensing of a threat.

Object detection portal with video display overlay

A probe instrument using room temperature magnetic sensor(s) (24) for noninvasively measuring variations in magnetic susceptibilities with sufficient resolution to monitor paramagnetic materials in a human body, such as iron in liver. Tissue response to an alternating current field applied by an applied field coil (18, 26, 28) is detected. Applied field coil dimensions are chosen for maximum response from the liver while minimizing effects from overlying abdominal tissue and at the same time not unduly increasing instrument sensitivity to the lung. To overcome variations in sensor output due to fluctuations in the applied field, change in ambient temperature and mechanical relaxation of the instrument, sensor sample distance is modulated. Detector assembly (10) is oscillated while the patient remains stationary. An improved water-bag technique is employed to eliminate background tissue response. The detector assembly forms part of a probe instrument for noninvasively detecting the paramagnetic concentration of a patient.

Simplified water-bag technique for magnetic susceptibility measurements on the human body and other specimens

Methods are disclosed for non-invasive screening of the human body by rejecting the magnetic response from biological tissues in the region of interest and outputting data corresponding to the magnetic response of a ferromagnetic foreign body within the region of interest.

Ferromagnetic foreign body detection with background canceling

A method and an apparatus are disclosed for applying a low strength, time varying magnetic field (26) to a selected screening region of a host, and for sensing a responsive magnetic field (28) from a retained ferrous body within the screening region. The excitation field coil is designed to create a region of finite magnetic field within the screening region, and a region of near zero magnetic field. The sensors (24) are placed within the region of near zero magnetic field to minimize the effect of the applied field. The effects of the applied field are further reduced by use of a reference sensor, field compensation coils, and a feedback loop. The magnetic gradient by the sensors (24) is processed to locate and characterize the ferrous body.
