Said equipment includes laser, ultrasonic wave generator component, acoustic sgnal measuring component, signal amplifier, data collecting card, three-D electric rotating platform and computer.

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 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.

The system, which retrofits existing brand mobile telephones by adding short range audio and command application and by adding a server to distance harmful radiation, comprises a server, a client mobile telephone having a long range and a short range transceiver, the client having a SIM module. The server has a short range and a long range transceiver and a second SIM module that has priority over the client with the network. The server, when in communication range with the client, receives the incoming call from the base station, transfers audio to the client by short range communication, receives audio from the client handset and transmit a signal corresponding to the audio to the base station. In a remote SIM version, instead of server having a physical second subscriber identification module, the client's SIM module data is sent by short range communication from the client to the server

An infant sleeping cap adapted for multi-functional use is disclosed, the infant sleeping cap includes a veil having a top surface, a bottom surface, and an elongate portion extending therebetween. The veil is attached to a stretchable band, and is adapted to (i) obstruct the peripheral and frontal vision of an infant to promote sleeping; (ii) block the sun from direct exposure to the infants eyes; and (iii) block ultraviolet and other harmful radiation from the rear-portion of the infant's neck. The infant sleeping cap can be positioned for wear in a variety of orientations.

The invention relates to a sonochemistrical luminous tomography method for tumour, which is that after distributing of sonosensitizer in tumour group, generating active oxygen-derived free radicals by scanning point by point and sensitizing used focusing ultrasound; translating the active oxygen-derived free radicals generated during sonosensitizing process real time and directly by chemical luminous agents into photons and radiating out; based on that, simulating the imaging of tumour group by optics detection technique. The apparatus comprises ultrasound producing groupware, light receiving groupware, A/D converter, triaxiality scanning device and computer; wherein ultrasound producing groupware and triaxiality scanning device link to computer, light receiving groupware and A/D converter link to computer in turn. The invention combines strong penetrating ability of focusing ultrasound to body and the advantages of high sensitivity and intactness of optics imaging, brings no radioactive damage to organism.

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.
