Patent number: 7413304Abstract: A grid formed with apertures of a predetermined shape is illuminated with light from a lamp and projected onto a tear meniscus accumulated on the lower eyelid. The aperture image projected on the tear film is imaged by a CCD camera. The tear meniscus functions as a concave mirror, so that the magnification factor depends on the radius of meniscus curvature. A processor calculates the magnitude of the grid image and evaluates the radius of meniscus curvature. Since the volume of lacrimal fluid varies depending upon the radius of meniscus curvature, the latter is used as a value representing the lacrimal fluid volume for dry eye diagnose purposes.Type: GrantFiled: June 26, 2007Date of Patent: August 19, 2008Assignees: Kowa Company LtdInventors: Takayoshi Suzuki, Norihiko Yokoi

Patent number: 7413338Abstract: An exemplary backlight module includes a frame (16) and a light guide plate (14) positioned in the frame. The frame defines a notch (164), which notch is bounded by a wall of the frame. The light guide plate includes a side surface (141), and an ear (144) extending from the side surface. The ear is received in the notch. A first protrusion (165) protrudes from either the wall of the notch or the ear and contacts the corresponding ear or wall of the notch.Type: GrantFiled: August 8, 2006Date of Patent: August 19, 2008Assignee: Innolux Display Corp.Inventor: Chun-Yun Pan

Patent number: 7413340Abstract: A dynamic heat flow meter is provided which introduces a measured air flow into the system adjacent the test sample (e.g., insulation product), for which thermal properties are to be measured. The heat flow meter then measures thermal properties (e.g., thermal conductivity and/or heat capacity) of the test sample taking into account air flow through and/or adjacent the test sample.Type: GrantFiled: March 7, 2007Date of Patent: August 19, 2008Assignee: Guardian Building Products, Inc.Inventor: Gary E. Romes

Patent number: 7413341Abstract: A method of local temperature measurement in a sample is provided. The method comprises the stimulation, at a location in the sample, of anti-Stokes and Stokes emission from fluorophores which are present at the location in the sample, measuring the intensities of the stimulated radiation and calculating the temperature at the location from the measured intensities. The method can be used to obtain a thermal image of the sample.Type: GrantFiled: August 16, 2005Date of Patent: August 19, 2008Assignee: The Research Foundation of State University of New YorkInventors: Aliaksandr Kachynski, Andrey Kuzmin, Haridas Pudavar, Paras N. Prasad

Patent number: 7413342Abstract: A converter comprising a comparator having a first input operable to receive a first signal, a second input operable to receive a second signal, and an output, a switch for sinking a portion of the first signal, wherein the switch is responsive to the output, and an integrator connected to the first input, wherein the first signal is a voltage developed by the integrator when a current proportional to the absolute temperature is applied thereto. A method for measuring temperature of a device using a comparator and converting the bitstream of the comparator to a digital output is also given. Because of the rules governing abstracts, this abstract should not be used to construe the claims.Type: GrantFiled: February 22, 2005Date of Patent: August 19, 2008Assignee: Micron Technology, Inc.Inventor: Sugato Mukherjee

Patent number: 7413343Abstract: An apparatus and method measure a temperature of a temperature sensing element having a temperature dependent resistance based on a ratio of discharge times of a capacitor through a reference resistance and through the combination of the reference resistance in parallel with the temperature sensing element is disclosed. A reference discharge time is determined by measuring the discharge time of the capacitor from a first voltage to a second voltage through a reference resistance. A temperature evaluation discharge time is determined by measuring the time to discharge the capacitor from the first voltage to the second voltage through the reference resistance in parallel with the temperature sensing element. The ratio of the temperature evaluation discharge time to the reference discharge time is used to determine the temperature and produce a digital representation of the temperature.Type: GrantFiled: September 16, 2005Date of Patent: August 19, 2008Assignee: Kyocera Wireless Corp.Inventor: John Philip Taylor

Patent number: 7413344Abstract: An object of the present invention is to provide a radiography system in which an FOV in a light field agrees with an FOV in an X-ray field irrespective of a displacement of a light source. The radiography system comprises an X-ray tube, a collimator that forms an X-ray beam to be irradiated from the X-ray tube to an object of radiography, and a light source that irradiates light, which is used for ranging, to the object of radiography via the collimator. The radiography system further comprises a memory in which the magnitude of a displacement of the light source calculated in advance is stored, and a control unit that controls the opening of the collimator on the basis of the position of the light source, which is corrected based on the magnitude of a displacement read from the memory, so that an FOV of light to be used for ranging will agree with a target value.Type: GrantFiled: June 20, 2006Date of Patent: August 19, 2008Assignee: GE Medical Systems Global Technology Company, LLCInventor: Lei Qian
