Abstract:
A holder for a telephone handset, in particular for use in cars, which is to provide a hands-free function comprises a stationary holder part and a pivotable holder part which can pivot relative to the former about a holder pivot axis between an open position, in which the pivotable holder part encloses an angle with the stationary hoder part, and a closed position, in which the pivotable holder part lies substantially parallel to the stationary holder part. The pivotable holder part has a connector which cooperates with a mating connector of a cordless telephone handset so as to achieve an automatic electrical connection thereof when a cordless telephone handset is inserted.
Abstract:
In an electron microscope it is sometimes important that specimens can be studied at a very low temperature (for example, that of liquid helium). In the case of known specimen holders the specimen is cooled by supplying the cooling medium via a bore in the specimen holder; this causes thermal drift of the removed specimen holder each time when a specimen is exchanged, and also an acoustic coupling (i.e. transfer of vibrations) exists with the dewar vessel connected to the specimen holder. In accordance with the invention, the specimen is arranged on the end ( 20 ) of the specimen holder (7) by means of a separate transport unit (13, 36) so that it is not necessary to remove the specimen holder (7) in order to exchange a specimen, with the result that the specimen holder is not heated. Moreover, the coupling to the cold source (22, 28) can take place via a flexible cooling conduit ( 30 ) which extends directly to the end ( 20 ) to be cooled and may be permanently connected thereto, thus avoiding the transfer of vibrations.
Abstract:
The invention relates to a reflective flat-panel color display device (1) having a diffusing display panel (3). The display panel (3) comprises a diffusing liquid crystalline material (5) present between a first and a second substrate (7, 9). A color filter pattern (15) which corresponds to the pixel pattern of the display panel (3) is present between the liquid crystalline material (5) and the second substrate (9). A diffusing reflector is present at the side of the color filter pattern (15) remote from the liquid crystalline material (5). In another embodiment, a reflector (17), which has a diffusing or non-diffusing effect, is present outside the display panel (3) and a forward diffuser (33) is arranged between this reflector (17) and the display panel (3).
Abstract:
A description is given of an optical inspection device for inspecting two oppositely located surfaces (3, 4) of a transparent object (1), for example a lithographic mask. The device is constructed in such a manner that for each inspection beam (a, c) the radiation path to the surface to be inspected (3, 4) is substantially equal to the radiation path from the surface to be inspected to a detector (29, 40), so that these paths comprise the same scanning element (10), preferably a mirror polygon. By virtue thereof, the radiation spots formed on the detectors are stationary and an inspection signal having a good signal-to-noise ratio is obtained.
Abstract:
A hair styling instrument comprises a housing (8) having a front side (9), formed with at least one passage (10) for heated air. Elongate hair guides (12, 13, 14) project exclusively from the front side (9) of the housing (8) or, at least in the area of the passage (10), fixed elongate hair guides (12, 14) project from the housing (8). Movable ones of the hair guides (13) are movable between a first position, in which they project fully from the housing (8), and a second position, in which they project from the housing (8) at the most to a smaller extent than in said first position. With the movable hair guides (13) in the second position the hair styling instrument can be moved through wet tangled hair with a low resistance. Subsequently, when the hair is tidied and dried, a proper grip and hence a satisfactory styling performance is achieved with the movable hair guides (13) in the first position.
Abstract:
An LCD display device for receiving encrypted video data and for decrypting the video data such that a signal is not provided "in the clear" before receipt by the display device. The video data is encrypted within a row of video and decrypted at the display. Alternatively the rows are encrypted by altering the time sequence of display of each row.
Abstract:
A display device for receiving encrypted or scrambled video data and for decrypting or descrambling the video data such that a signal is not provided "in the clear". The video data is stored in a memory array in an encrypted form and read out from the memory array using a decryption key. The encrypted data is then read out from the memory elements in accordance with known methods.
Abstract:
Method of providing a pattern of apertures and/or cavities in, for example, a glass duct plate of a plasma-addressed liquid crystal display, in which first a mechanical treatment is performed (for example, by means of powder blasting) and then a wet-chemical etching treatment is performed to render the walls of the ducts microscopically less rough so that the optical disturbance is reduced and the glass becomes clearer again.
Abstract:
In a toothbrush (1) comprising a grip member (2) and a brush member (36) connected to the grip member (2), which brush member has a longitudinal axis (39) and carries a bristle holder (40) which is mounted on the brush member (36) so as to be movable with respect to a holder axis (41) and which has a holder surface (69) which extends substantially transversely to the holder axis (41) and from which, in the area of the holder surface (69), bristles (70) project transversely to the holder surface (69) and together form a bristle field (71), the free ends of at least a part of the bristles (70) of the bristle field (71) arranged around the holder axis (41) are bounded by two non-stepped enveloping surfaces (72, 73) which are inclined continuously with respect to the bristle holder (40), which enveloping surfaces are arranged substantially in a V-shape relative to the holder surface (69) of the bristle holder (40) and intersect one another along a line of intersection (74) at the location of the holder axis (41), the line of intersection (74) of the two enveloping surfaces (72, 73) extending transversely to the longitudinal axis (39) of the brush member (36).
Abstract:
The invention relates to an integrated circuit, comprising a number of independent clock domains. Seam circuits are provided in the interface signals paths between the clock domains in order to be able to isolate clock domains from each other during testing. Each seam circuit comprises a feedback loop having a multiplexer and a flip-flop feeding a first input of the multiplexer, a second input of the multiplexer being connected to the seam input, an output of the feedback loop being connected to the output; so that a first state of the multiplexer allows loading of a data bit in the feedback loop via the seam input, and a second state of the multiplexer freezes the data bit in the feedback loop.
