Patent EP-0303316-A2 (EP)
Inventor: FERNANDO GERARD MARIUS XAVIER
IPC: H04N7/015
Filed: 1988-08-02
Abstract: A television signal for a television transmission system conveys a motion information signal in addition to the vision signal. At the transmission side each field of a picture is subdivided into a plurality of regions and up to a given number of the most dominant motion vectors appropriate to a region are generated. These motion vectors are transmitted as the motion information signal and in a receiver are separated from the television signal in a decoder (12). The spatially offset pixels are identified in a first spatial offset circuit (14) from a vision signal delayed by a picture memory (16) and compared in a picture information comparison circuit (17) with pixels in the corresponding field of the current picture to identify the motion vector indicating the pixel of corresponding magnitude. This is applied to an input of a second spatial offset circuit (19) a second input of which receives the delayed vision signal to produce motion compensated pixels which together with pixels from the current vision signal are up-converted and interpolated in a unit (18) to produce an up-converted vision signal.

Abstract: A spherical lens (3), which is arranged between the photoelectric component (2) and the optical waveguide (4) in the transmitting or receiving module of a photoelectric transmission link, is held in a support (5), which allows positioning of the spherical lens in the beam path of the transmission link in all three coordinates (X, Y, Z). The support (5) consists of two legs, bent in the shape of a V, of which one accommodates the spherical lens while the other has a cutout (6) for the optical radiation. The support is welded via lugs (7, 8) at the free ends of the legs to a base (1). By varying the splay angle ( alpha ) between the two legs of the support (5), the spherical lens (3) can be adjusted in its height above the base (1) before it is finally fixed. The device is intended to be employed with optical waveguide transmitting and receiving modules. <IMAGE>

Abstract: When the reference clock (fr) fails for a short time, the voltage-controlled oscillator (VCO) of the phase-locked loop (PLL), the output clock of which determines the clock of the clock generator, continues to be operated with the control output voltage valid until then. When the reference clock returns, the phase difference between reference clock (fR) and output clock (fn) of the oscillator is again measured and corrected with the value of the corresponding phase difference valid before the failure of the reference clock. The corrected value is used as a basis for the resumed frequency control.

Abstract: This invention provides for the most amount of concurrency of I/O and CPU processing by adding an intelligent hard­ware circuit which controls memory bus ownership between the CPU and DMA controllers. This intelligent circuitry monitors CPU requests for main memory access and exter­nally negates the I/O device's DREQ request signal. This in turn temporarily halts the I/O transfer, and allows the CPU to steal a bus cycle in the middle of an I/O transfer burst.

Abstract: An NMR method for acquiring the  in vivo  proton spectra of spin-spin coupled metabolites employs a series of stimu­lated echo pulse sequences (90-TE/2-90-t₁-90-TE/2). The value of period t₁ is different for each of the pulse sequences in the series, and the NMR signals produced by the series of pulse sequences are acquired and digitized to form a two-dimensional data array. A two-dimensional Fourier transformation is performed on this data array to produce an array of data that is employed to generate a contour plot.

Abstract: The present invention pertains to a crosslinkable binder resin comprised of an acrylate copolymer backbone having as pendant groups water soluble half esters of dicarboxylic acid and crosslinkable olefinic groups which contain an activated ethylenic unsaturation, such as (meth)acryloyl groups. The (meth)acryloyl groups can be crosslinked by polyfunctional crosslinking agents such as amino or blocked amino crosslinkers. The water-soluble half esters preferably are formed by the reaction of pendant hydroxy groups with unsaturated cyclic anhydrides (the unsaturation providing an additional crosslinking site). The (meth)acryloyl groups preferably are formed by the reaction of pendant epoxy groups with (meth)acrylic acid or derivatives thereof.

Abstract: The methods known in optics for determining surface structures permit only a determination of the surface characteristic, but not the determination of the structures located closely underneath the surface. The subject matter of this application is to overcome this disadvantage of the known determination capabilities to the extent that not only can just the surface characteristic be determined by the method but also, at the same time, the structure underneath the surface to the depth of approximately one wavelength. Devices for carrying out the method are likewise proposed. To carry out this method, it is proposed that the object to be determined, which is resting on a flat or domed surface, be subjected to ultrasonic waves through a solid body or through a body filled with fluid and thus the waves which are scattered back and reflected as a result of the sound striking the object be recorded by a receiver, the wavelengths of the ultrasonic waves being matched to the structure of the respective object. Conclusions on the characteristics of the surface and of the deep structure can be drawn from the intensity of the waves which are scattered back and reflected. <IMAGE>

Abstract: A sheet feeding device includes a vibration member (A, B) having at least one circular-arc portion, for generating a travelling wave, and a sheet guide (21) for guiding a sheet (13). Since an amplitude of vibration at an inner circumferential side of the vibration member (A, B) is smaller than an amplitude of vibration at an outer circumferential side, a distortion is produced in the vibration member (A, B) in a direction perpen­dicular to the direction of movement of the sheet (13). The sheet guide (21) is provided at an inner circumferential side of the vibration member (A, B), so that the sheet (13) is fed due to the dis­tortion while being pressed against the sheet guide (21). Hence, an oblique movement of the sheet (13) due to unevenness in the thickness of the sheet (13) can be prevented.

Abstract: A battery charger (14) for a portable wireless telephone set (10) comprising a rapidly charging circuit (18) for rapidly charging the battery by a first charging current of a high level at a start of the charging operation, a tricklingly charging circuit(19) for tricklingly charging the battery by a second charging current of a considerably low level, and a charge controller (24) for making the tricklingly charging circuit take over the rapidly charging circuit after a charge detecting circuit (20) detects that the battery (11) is rapidly charged to its normal voltage. In order to avoid that the battery (11) is insufficiently charged by the tricklingly charging circuit (19) when the telephone set (10) is left in a power-on condition, the battery charger (14) further comprises another charging circuit (23) for supplying a third charging current which is lower than the first charging current but higher than the second charging current. When the telephone set i10) is in the power-on condition, the charge controller (14) operates not the tricklingly charging circuit (19) but the other charging circuit (23) after the battery (11) is rapidly charged to its normal voltage, so that the battery (11) can be charged to the normal voltage even if the telephone set (10) is left in the power-on condition.

Information stored in the memory cell depends on whether or not the carrier traps (13) are holding carriers, and the information is read out of the memory cell as the difference of a tunneling current flowing between the semiconductor substrate (11) and the high-concentration impurity region (12).
