Abstract: An x-ray tube includes an envelope (13) defining an evacuated chamber and having a
window (30) transmissive to x-rays. An anode assembly and a cathode assembly
operate within the envelope to produce x-rays which travel through the window
transmissive to x-rays towards a patient or subject under examination. A shield
transmissive (32) to x-rays is coupled to the envelope and positioned such that x-rays
travelling through the window transmissive to x-rays must first travel through the
shield. The shield prevents substantially all secondary electrons created during the
production of x-rays from coming into contact with the window transmissive to x-rays
thereby preventing excessive heating of the window transmissive to x-rays. An
electrode (50) defined by the envelope in a region proximate the window transmissive
to x-rays may additionally or alternatively be used to prevent secondary electrons from
reaching the window transmissive to x-rays.

Abstract: An automatic toilet seat (40) having two electric drives functioning independently of one another is provided. One motor (5) is connected to the seat (11) and the other (4) operates a paper gripper. Both motors (4,5) are controlled by appropriate sensors and by an intelligent microprocessor control device. This particular technological model has the advantage that, due to the separate arrangement with one drive motor (5) for the pivot drive (7) of the seat (11) and, independent of that, one drive motor (4) for seizing the protective cover (30), it is possible to operate both drives completely separately from one another and thus to link the drives by an intelligent microprocessor control. With the intelligent microprocessor control unit, it is possible to adjust the two drives independently of one another and to adjust both of them to the site conditions (i.e., the location where the toilet seat is installed). <IMAGE>

Abstract: An image-processing apparatus, as well as an image-processing
method, is provided with a first inspection
circuit which, with respect to density values of pixels
within a specific area consisting of a target pixel and
pixels in a vicinity thereof in image data for each color
component, calculates an average density value, the sum of
density differences, that is, the sum of absolute values of
differences between the target pixel and the peripheral
pixels, and the number the peripheral pixels having the same
density value as the target pixel, so that a judgement is
made as to whether the target pixel is a maximum value or a
minimum value, and also calculates a run-length and the
degree of busy from the pixel forming the maximum value or
the minimum value. Moreover, based on the run-length and
the degree of busy, the second inspection circuit extracts
a pixel weight switching signal for each of the color
components, and detects the periodicity of meshes of image
data by counting pixels not less than the standard value or
not more than the standard value based on the pixel weight
switching signal within a predetermined counting area. With
this arrangement, it becomes possible to carry out the
discrimination between character areas and mesh areas as
well as the discrimination between black character areas and
white character ares with high precision.

Abstract: A network repeater having a plurality of repeater ports selectively establishes links with remote
nodes at one of two data rates based on the capabilities of the remote network node and a determined link
integrity. A network repeater establishes a link with a network node using auto-negotiation techniques to
establish a 100 Mb/s link. The network repeater than monitors the link for symbol errors, and determines
an integrity of the link based on a detected number of symbol errors relative to a prescribed threshold. If
the detected number of symbol errors reaches the prescribed threshold, indicating poor link integrity due to
poor cable connection or condition, faulty network device, etc., the network repeater performs a down
shifting operation by breaking the established 100 Mb/s link, and restarting auto-negotiation to establish a
10 Mb/s link. Hence, the network repeater may monitor high-speed links for link integrity, and selectively
downshift a link encountering a substantial number of errors to a reduced data rate, without a necessity of
a network manager or other remote management function.

Abstract: The present invention provides a flame sensor having dynamic sensitivity
adjustment, wherein the sensitivity of the flame detector can be adjusted by varying the
gain of a signal conditioning circuit associated with the flame detector. The flame detector
includes a photodiode (D4), such as, for example, a silicon carbide (SiC) photodiode, that,
when exposed to electromagnetic radiation having a wavelength in the range of from about
190-400 nanometers, and preferably within the ultraviolet range, generates a photocurrent
proportional to the radiation intensity. The output of the photodiode is processed and
amplified by signal conditioning circuitry (U1A, U1B, Q2) to produce a signal indicative
of the presence of a flame. Moreover, a cutoff wavelength for silicon carbide photodiodes
is preferably in the range of about 400 nanometers, which renders the photodiode "blind"
to potentially interfering blackbody radiation from the walls of the turbine.
