A transparent marker casing for use with a tracking system, comprising a material that is transparent to radiation emanating from at least one marker, wherein the marker casing is formed such that it at least partially surrounds the at least one marker. The casing can include a moisture sensor that can detect moisture or liquid on a surface of the casing and provide a signal indicative of the presence of moisture.

A device for administering brachytherapy to a patient includes a vessel that may be in the form of a hollow cylindrical cup, for fleshing into and substantially filling the open-ended cavity. The vessel has a closed outer end, which may be a removable cover, and a source guide penetrates the closed outer end so as to extend deep into the vessel, to receive a radiation source in the source guide. A manipulator can be connected to the radiation source, and also to the source guide, for allowing several different types of manipulation of the source orientation and position within the vessel during the brachytherapy procedure.

The present invention discloses an evaporative cooling clothing system for reducing body temperature of a wearer of the clothing system. The clothing system includes a clothing article configured using a wicking fabric and a hollow transport defining a cavity for transporting a liquid from a liquid reservoir to an upper region of the clothing article. The hollow transport has an intake section and a dispensing section. The intake section is attached to the liquid reservoir for receiving the liquid, and the dispensing section is attached to the upper region of the clothing article. The upper region of the clothing article receives the liquid from the dispensing section and transfers the liquid to a lower region of the clothing article. The lower region of the clothing article exposes the liquid to an environment surrounding the clothing article for evaporation.

A method for measuring photoacoustic signals in biological tissue includes emitting laser pulses into biological tissue to generate photoacoustic field, emitting a focused ultrasonic beam into the photoacoustic field to superpose on photocoustic signal and generate its beat signals, receiving and measuring them, separating signal spectrum, and extracting photoacoustic signals. Its apparatus is composed of laser device, ultrasonic generator, sound signal measurer, signal amplifier, data acquisition card, and computer. It can diagnose the lesion of biological tissue with radiactive damage.

A protective skin shields system that is mounted to eyeglasses worn by a user. The major components are a means for mounting, an interconnected and shields. The invention solves technological problems, inter alia, of bilaterally protecting the cheek, temple and forehead region of a user's face from harmful sun radiation without the use of hats, skirts, blockers and / or chemicals.

A device for providing solar and ultraviolet radiation protection to facial skin. The device has a configuration at a high level of abstraction that resembles eye glasses. The device is comprised of symmetrical halves. In one embodiment, each of the symmetrical halves is comprised of a noise bridge having a flexible and resilient vertex and extension arms, a cheek shield and a temple arm.

The present invention relates to the protection of medical patients and personnel from harmful radiation. More specifically, this invention provides a compact, light-weight article to be worn in areas of the body most sensitive to radiation. These include, for example, the pelvic area, the genital and gonad areas, the breast area to guard against radiation to the mammary gland, the neck and throat to protect the thyroid gland, the eye area to protect the crystalline lens.

The focussing ultrasonic modulation reflection type optical chromatographic imaging method utilizes the focussing ultrasonic technique to make modulation and tissue location of the laser injected into deep biological tissue, and uses optical technique to make high-sensitivity detection and real-time high-speed. Fourier transform to process signal, and can obtain the chromatogram of pathologic changed tissue region. The injection laser mand modulation ultrasonic wave are coaxially-retained, and its signal exciting device and receiving device adopt homoside reflection mode. Said optical chromatographic imaging equipment is formed from laser, optical polarization component, ultrasonic component, photo-electric conversion component, signal display and real-time rapid Fourier transform module and computer.

An acoustic wave conductor assembly for mitigation of harmful radiation inherent in a mobile device belonging to a user. The assembly includes an acoustic wave conductor designed ergonomically for insertion into the external auditory ear canal of the user's ear and connecting means between the acoustic wave conductor and the user's mobile device, such that the user is enabled to hear telephone conversations, but keep the mobile device at a safe distance from his head and all his vital tissues, wherein the assembly is simple, efficient, economical and effective.

The present invention discloses a SAR radiation-free mobile terminal body, a SAR radiation-free external communication body and a SAR radiation-free mobile terminal. The SAR radiation-free mobile terminal comprises the SAR radiation-free mobile terminal body. The SAR radiation-free external communication body is disposed outside the SAR radiation-free mobile terminal body and is connected with the SAR radiation-free mobile terminal body through optical fibers. The SAR radiation-free external communication body comprises a communication module connecting with a communication base station without affecting the compatibility and normal radiation power of communication equipment; inter-conversion between electric signals and optical signals is realized through a photoelectric conversion module. Signals are transmitted between the SAR radiation-free external communication body and the SAR radiation-free mobile terminal body through optical fibers mainly made from non-metallic materials, so that conduction of microwave radiation is avoided, thus, effectively avoiding the harm of mobile phone radiation to human bodies.
