An apparatus is described for use in combination with a noninvasive ophthalmological method for cornea reshaping in order to correct ocular refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. This apparatus is called a coupler and it is made of a material which is substantially transparent to the light energy used to reshape the cornea. The coupler conducts heat from the anterior portion of the cornea during the heating of the stroma by the light energy. The reshaping is enhanced by the coupler as it has a corneal engaging surface with a radius of curvature which approximates the desired emmetropic shape of the cornea. In addition to being a heat sink and template for the eye, the coupler also acts as a positioner and restrainer of the eye by attaching itself to the eye via an annular suction ring. Finally, the coupler also acts as a mask to prevent accidental exposure of the central optic zone to any light energy during the cornea reshaping procedure.

A phosphor (photo-luminescent) material based authentication system in which a blend (mixture) of at least two, preferably three or more, phosphor materials are used as a photo-luminescent security marking which is applied to or incorporated within an article/document to be authenticated. Preferably, the phosphor materials are each excitable by “eye safe” excitation radiation comprising visible light of wavelength 380 nm to 780 nm. Moreover, when excited the security marking preferably also emits visible light thereby minimizing any risk of damage to an operator's eye in the event of accidental exposure to the excitation radiation and/or light generated by the photo-luminescent marking. The authenticity of the article/document can be authenticated by verification of the composition of the phosphor by exciting the marking and comparing one or more selected parameters of light emitted by the security marking with corresponding parameters of the characteristic emission spectrum of the authentic phosphor blend.

The invention relates to the field of drug development against acute radiation injury caused by exposure to high-energy electromagnetic waves (X-rays, gamma rays) or particles (alpha particles, beta particles, neutrons). To date, there is no effective drug to ameliorate radiation injury after accidental exposure to ionizing irradiation. The invention provides a method of treating radiation injury of a subject in need thereof comprising administering to the subject a peptide, or functional analogue or derivative thereof, of smaller than 30 amino acids. Furthermore, the invention provides use of a peptide, or functional analogue or derivative thereof, of smaller than 30 amino acids for the production of a pharmaceutical composition for the treatment of a subject suffering from or believed to be suffering from radiation injury. In particular, the invention provides anti-radiation peptides having a dose reduction factor (DRF) against acute gamma irradiation of at least 1.10, said DRF determinable by testing which dose of radiation results in 50% mortality at 30 days (LD50/30) after whole body radiation (WBI) in a test group of mice treated with said peptide at 72 hours after WBI and, testing which dose of radiation results in 50% mortality at 30 days (LD50/30) after whole body radiation (WBI) in a control group of mice treated only with the vehicle of said peptide at 72 hours after WBI and wherein the DRF is calculated by dividing the LD50/30 of the peptide-treated animals by the LD50/30 of the vehicle-treated animals.

An improved angiocatheter device for introducing intravenous fluids or drugs into the lumen of a patient through a sheath. At the point of the procedure where a needle needs to be removed but the sheath is to remain implanted, a spring in the needle portion of the device is expanded thereby retracting the needle and allowing the operator to remove the needle from the sheath and an introducer hub. This feature allows for quick insertion and removal from the patient without the necessity of sliding or otherwise removing the needle from the sheath in a multiple step process. In this manner, the catheter or lead can implanted quickly and safely while also protecting the operator from accidental exposure to the patient's blood and eliminating the need to apply positive pressure to the lumen while the needle is being removed.

The invention discloses a method for updating a key and system. The method comprises the following steps that: (1) a background authentication system receives the current dynamic password generated by a dynamic token to carry out the authentication of the current dynamic password, if the authentication is successful, then the key updating information is generated, and step (2) is performed; and (2) the background authentication system generates a first updated key according to the key updating information and a first initial key stored in the background authentication system, and the first updated key is copied to a buffer area of the first initial key; the dynamic token obtains the key updating information to carry out the authentication of the key updating information, if the authentication is successful, a second updated key is generated according to the key updating information and a second initial key stored in the dynamic token, and the second updated key is copied to a buffer area of the second initial key; and otherwise, the key updating operation is cancelled. According to the technical scheme of the invention, the risk caused by the accidental exposure of the key can be prevented.
