Initiating medical system communications
A medical system includes a body-contacting signal source adapted to transmit an oscillatory signal though a body to a transducer of a device implanted therein. A detector that is coupled to the transducer, upon detection of a response of the transducer to the signal, activates a radio-frequency (RF) telemetry component of the device.

Body contacted dynamic memory
InactiveUS6111778AEfficiently store and retrieveIncreases magnitudeTransistorSolid-state devicesBody contactMemory circuits
A dynamic memory circuit in which the inherent bipolar transistor effect within a floating body transistor is utilized to store an information bit. A floating body of a storage transistor stores an information bit in the form of an electric charge. The floating body is charged and discharged via an access transistor during data write operations. The inherent bipolar transistor resident within the floating body transistor increases the effective capacitance of the floating body which acts as the storage node, and thereby enhances the magnitude of the discharge current which represents the stored information bit during read operations.

ActiveUS20070152812A1Enhanced signalAcoustic sensorsAuscultation instrumentsAmbulatory systemFrequency spectrum
A system and method that uses a non-invasive method, such as a wearable module equipped with sensors placed on a subject connected to a computer-linked module, to monitor life signs like heartbeat waveforms and body temperatures. Life signs indicate the health of a living being or a dynamic system (a mechanical system containing moving parts, like motors). The health of the system is defined by a set of known good spectra (such as its frequency / wavelet transform spectrum), with deviations triggering alerts. A garment embedded with a piezoelectric material and an electronic temperature sensor, when placed in contact with the body, captures acoustic waves from the heart and body temperature. Both sensors are connected to a garment-mounted module with an embedded flexible printed antenna (WEM). A separate WEM with reconfigured daughterboard software forms a bidirectional wireless data connection to a computer. A software program compares the received spectrum to its database spectrum and alerts the user when deviation is determined by a set of rules.

An ultrasound coupling device for acoustically coupling an ultrasound transducer with a patient's body comprises a fluid chamber having an ultrasound transducer interface for placing an ultrasound transducer in contact with water within said fluid chamber. The coupling device also has a patient interface comprising a water permeable membrane. The membrane has an internal membrane surface which is in contact with the water in the water tank and an external membrane surface can be placed in contact with the patient's body. The membrane is specially designed to allow water from inside the water tank to slowly permeate or “leak” to the external membrane surface while such surface is in contact or placed in very close proximity to the patient's skin. The slow permeation rate maintains the external membrane surface wet and free of air bubbles during a procedure which can take several hours. At the same time, the slow rate of permeation does not cause any water spillage around the patient.

The Ice Belt To Reduce Body Temperature is a belt made of a turned out strip of flexible material of amble width and length to gird the waist from the midriff down, contains pocket-like receptacles on its innermost body-contacting side for the placement of flexible ice bags, and is secured around the waist by a connecting means. The Ice Belt to Reduce Body Temperature is a new concept of belts intended for sports, exercise and safety because the Ice Belt To Reduce Body Temperature provides the wearer with the comfort of a lower body temperature when exposed to high climatic conditions. In fact, most belts pertaining to the prior art are designed to promote sweating—a symptom of high body temperature—rather than reduce sweating. Therefore, the Ice Belt helps to lessen the risk of the user acquiring heat exhaustion when exposed to high climatic conditions.

Method of forming a body contact using BOX modification
A novel method for forming substrate contact regions on a SOI substrate without requiring additional space, and in order to provide lower diffusion capacitance. The method utilizes known semiconductor processing techniques. This method for selectively modifying the BOX region of a SOI substrate involves first providing a silicon substrate. Then, ion implanting the base using SIMOX techniques (e.g. O2 implant) is accomplished. Next, the substrate is photopatterned to protect the modified BOX region. Then, further ion implanting using a "touch-up" O2 implant is accomplished, thereby resulting in a good quality BOX as typically practiced. The final step is annealing the substrate. The area of the substrate, which had a mask present, would not receive the "touch-up" O2 implant (second ion implant), which in turn would result in a leaky BOX.
