The present invention provides a method and apparatus for controlling the internal body temperature of a patient. According to the present invention, a catheter is inserted through an incision into a large blood vessel of a patient. By selectively heating or cooling a portion of the catheter lying within the blood vessel, heat may be transferred to or from blood flowing within the vessel and the patient's body temperature may thereby be increased or decreased as desired. The invention will find use in treating undesirable conditions of hypothermia and hyperthermia, or for inducing a condition of artificial hypothermia when desired.

The camera unit includes a video camera, a rotatable mirror system for directing images of the security area into the video camera, and a ranging unit for detecting the presence of a target and for providing target range data, comprising distance, angle and width information, to the camera unit controller. The camera unit controller includes software for detecting face images of the target, tracking of detected face images, and capture of high quality face images. A communication system is provided for sending the captured face images to an external controller for face verification, face recognition and database searching. Face detection and face tracking is performed using the combination of video images and range data and the captured face images are recorded and/or made available for face recognition and searching.

LED epitaxial layers (n-type, p-type, and active layers) are grown on a substrate. For each die, the n and p layers are electrically bonded to a package substrate that extends beyond the boundaries of the LED die such that the LED layers are between the package substrate and the growth substrate. The package substrate provides electrical contacts and conductors leading to solderable package connections. The growth substrate is then removed. Because the delicate LED layers were bonded to the package substrate while attached to the growth substrate, no intermediate support substrate for the LED layers is needed. The relatively thick LED epitaxial layer that was adjacent the removed growth substrate is then thinned and its top surface processed to incorporate light extraction features. There is very little absorption of light by the thinned epitaxial layer, there is high thermal conductivity to the package because the LED layers are directly bonded to the package substrate without any support substrate therebetween, and there is little electrical resistance between the package and the LED layers so efficiency (light output vs. power input) is high. The light extraction features of the LED layer further improves efficiency.

A method of forming a silicon nitride film comprises: forming a silicon nitride film by applying first gas containing silicon and nitrogen and second gas containing nitrogen and hydrogen to catalyst heated in a reduced pressure atmosphere. A method of manufacturing a semiconductor device comprising the steps of: forming a silicon nitride film by the method as claimed in claim 1 on a substrate having the semiconductor layer, a gate insulation film selectively provided on a principal surface of the semiconductor layer, and a gate electrode provided on the gate insulation film; and removing the silicon nitride film on the semiconductor layer and the gate electrode and leaving a sidewall comprising the silicon nitride film on a side surface of the gate insulation film and the gate electrode by etching the silicon nitride film in a direction generally normal to the principal surface of the semiconductor layer. A method of manufacturing a semiconductor device comprising the steps of: forming a silicon nitride film by the method as claimed in claim 1 on a substrate including a semiconductor layer; forming an interlayer insulation layer on the silicon nitride film; forming a layer having an opening on the interlayer insulation layer; and etching the interlayer insulation layer via the opening in a condition where an etching rate for the silicon nitride film is greater than an etching rate for the interlayer insulation layer.

Consistent with the present invention, tissue adhesive compositions and an associated laser exposure system are provided for bonding or sealing biological tissues. The compositions are comprised of chemically derivatized soluble collagen which is formulated to concentrations ranging from 300 mg/ml (30%) to 800 mg/ml (80%) collagen protein. In particular, Type I collagen, for example, is first prepared by extraction from bovine or porcine hide and purified. The collagen preparations are then chemically derivatized with sulfhydryl reagents to improve cohesive strength and with secondary derivatizing agents, such as carboxyl groups, to improve the adhesive strength of the solder to the tissue. The compositions are then formed into viscous solutions, gels or solid films, which when exposed to energy generated from an infrared laser, for example, undergo thermally induced phase transitions. Solid or semi-solid protein compositions become less viscous enabling the high concentration protein to penetrate the interstices of treated biological tissue or to fill voids in tissue. As thermal energy is released into the surrounding environment, the protein compositions again become solid or semi-solid, adhering to the treated tissue or tissue space.

A safety catheter device for hemodialysis and donor collection (see FIG. 9) comprises a catheter unit (101), a needle (105) guided by a needle port (114) into the catheter unit to introduce it into patient's vein, an indication channel for blood supply into an indication cavity (109) during catheter emplacement, a blood stream channel for blood supply to hemodialysis or collection set through a blood stream port (112). The minimal cross-sectional area of the blood stream channel is substantially more than one of the indication channel. Forming the blood stream channel is accomplished by retracting the needle and, in version embodiment, by rotating a port unit (111) including the needle and blood stream ports relative to the catheter unit. There are means preventing blood leakage and personnel infecting.

When configuring a film antenna for receiving a circular polarized wave, at least one loop antenna is formed on a transparent plastic film and, at the same time, a non-powered element constituted by a wire-shaped conductor independent from the antenna conductor configuring the loop is arranged near this loop antenna. The non-powered element arranged on the side of the loop antenna is configured by a first part and a second part. The first part is made close to the loop antenna in a substantially parallel state. When a monopole antenna is used in place of the loop antenna, by combining this with a wire-shaped conductor orthogonal to this, it becomes possible to receive a circular polarized wave by a configuration providing a power transfer part between the two. It is also possible to configure a composite antenna by mounting another antenna on the transparent plastic film. This antenna can be used as an antenna of a navigation system.
