Title: Non-invasive determination of glucose concentration in body of patient
Inventor: BARNES RUSSELL H
IPC: A61B5/00
Filed: 1991-12-03
Granted: 1996-03-26
Abstract: Radiation in the near infrared over a limited range of wavelengths about 1660 nanometers is projected on a portion of the body, for example, the ear, of the patient. The resulting radiation emitted by the portion, either scattered from the portion or transmitted after absorption and scattered by the portion, is processed to derive an expression of the resulting radiation as a function of the wavelength.  The second derivative of this function over a very narrow range of this function between 1640 and 1670 nanometers is expanded and the glucose concentration is determined from the magnitude, or intensity, of the scatter-ed or transmitted radiation at the maximum or minimum point of this derivative.  Also disclosed is apparatus for non-invasive determination of glucose concentration in the patient.  Radiation in the near infrared is transmitted through a first fiber-optic radiation conductor to the outer surface of a portion of the patient's body, penetrating into the portion.  A second fiber-optic conductor transmits the resulting radiation emitted from the portion to data proces-sing means which produces the desired second derivative as a function of the wavelength of the incident radiation.  The processor includes a spectrum analyzer which produces a spec-trum of the resulting radiation.

Abstract: A door closer having a return spring for accumulating a recovering force in a door closing direction at the time of opening a door for performing a braking force by a damper at the time of closing the door which comprises a closer body internally containing a mechanism for performing an operation as the damper in a body case, an adjusting arm coupled perpendicularly to a driving shaft for the damper of the closer body to be projected laterally rotatably, a coupling bracket for pivotally securing an upper frame mounting plate directly or indirectly to the end of the adjusting arm via step screws to be horizontally rotatable, and a door mounting arm projected laterally from the closer body for pivotally securing a door mounting bracket to the end of the arm via a step screw to be horizontally rotatable.  Thus, the door closer can obviate a concept of mounting the closer body at the door to eliminate necessity of mounting a large closer body at the door by disposing a closer body as a damper at the pivotally securing position of the arm and the adjusting arm, thereby deleting impossibility of mounting the door closer even at a glass engaging door.

Title: Mechanical security device for facsimile machines
Inventor: HORTON HARRY M
IPC: B41J13/10
Filed: 1992-07-14
Granted: 1996-02-13
Abstract: An apparatus is provided to secure a facsimile machine and provide a secure receptacle portion adapted to receive and retain paper output from facsimile machines, so as to ensure the security and confidentiality of paper output from facsimile machines, so that the paper output is not accessed or readexcept by persons authorized to do so. The apparatus accommodates the usual operating function of a facsimile machine such as inputting paper having writtenmessages to be sent elsewhere and receiving the paper output of messages received from elsewhere. A base portion supports the facsimile machine on a horizontal surface and secures it thereto. A cover portion generally covers the facsimile machine and precludes it from being removed from the base portion. The receptacle portion and the cover portion are moveable with respect to each other so as to provide selectively securable access to the interior of the receptacle, being limited only to those who have a key or other means to open the receptacle. The cover for the entire apparatus also serves to secure the facsimile machine against unwanted or unwarranted removal away from its position.

Title: Method for controlling a pipe bending machine
Inventor: SCHWARZE RIGOBERT
IPC: B21D7/025
Filed: 1992-08-18
Granted: 2003-11-04
Abstract: A pipe bending machine has a bending template (10) around which a pipe (13) is bent. The bending template (10) is provided with a position sensor (32) that detects the bending path in dependence on the rotational position. A pushing device (17) engages the unbent portion (13a) of the pipe and urges the same towards said bending template (10). The pushing device (17) is provided with a position sensor (30). The position signals (PS1, PS2) of the two position sensors (32, 30) are compared in a control circuit (41) and an actuation signal (SS) is generated for controlling a pressure controller (42) to adjust the pressure of the drive (22) of the pushing device (17). The actuation signal (SS) is generated such that, in the case of equal position signals (PS1, PS2;), the drive (22) of the pushing device (17) is supplied with a pressure that determines the upsetting force exerted on the pipe.

Title: Compression and reconstruction of radiological images
Inventor: WILSON DENNIS L
IPC: H03M7/36
Filed: 1993-06-08
Granted: 1999-08-17
Abstract: The present invention provides for a compression scheme (10) tailored to the compression of large radiological images processed with image processing workstations.      The compression scheme (10) is a variation of the CCITT JPEG compression scheme with special care taken to suppress blocking effects of the 8x8 discrete cosine transform used therein. In accordance with the present invention, an original image (11) is downsampled (12), then interpolated (14) back to its original size, resulting in a smoothed image (14a). The difference (13) between the smoothed image (14a) and the original image (11) is then compressed (15) using an 8x8 discrete cosine transform with 12 bit data. Major artifacts present in the original image (11) are due to the mis-matching of the low frequency components of the image at the edges of the blocks. When the low frequencies are removed by subtracting out the low frequency components, the artifacts disappear except in areas having very large dynamic changes. The compression scheme (10) of the present invention is particularly useful for archiving or telecommunicating images, achieving compression of more than 10:1 without losing the characteristics of the radiological image that permit effective diagnosis. A  reconstruction scheme is also disclosed which allows recovery of the image (11) from a compressed image file.

The speed of the motor (46) driving the star feeder valve (42) is used to develop a control signal for the disk screen motor (13), to ensure a uniform flow rate off the disk screen.

Title: Pipelined image processing system for a single application environment
Inventor: VENABLE DENNIS L
IPC: G06T1/20
Filed: 1994-04-13
Granted: 2000-06-27
Abstract: A control system for pipelined image processing emulates a multi-tasking environment using a single tasking application. A number of predefined image processing tasks are provided in a library. When a host application needs a processed image from an image source, the host application creates a pipeline of initialized instantiations of one or more of the tasks from the library. When the host application invokes the pipeline, the first data request for the heater of the image travels upstream in a first channel. The processed image header is returned down the first channel.      Then a data request for scanlines of image data is sent upstream in a second data channel. The data request ripples upstreamwardly to the upstream-mast instantiation of one of the tasks from the task library. The upstream-most instantiation of a task obtains a scan line from an image data source and returns it downstreamwardly to the host application in the second channel. Each instantiation of a task from the task library further operates on the image data. Once all of the scanlines have been processed, the memory allocations and data structures created during initialization are released to free up that memory.
