Apparatus for controlling relative movement of an optical head to an optical disk with velocity detection. VX signals and PB.

Henri Abraham

A current limiting circuit generates a limited current signal sequentially variable with the negative temperature characteristic for the temperature of the cold sensor and controls a drive current of the output transistor to a current value depending on the signal level of the limited current signal when the overtemperature detecting signal is asserted.

The system pre-computes whether i the reference point of each corresponding tile in each plurality of tiles of each surface is visible or not from ii the reference point of each possible spawning tile in each other plurality of tiles. The laser-induced grating is configured to divide the leaky mode multivibratrur into multiple orders, each bent at a different angle.

An RF signal switch circuit that allows connection of any of N radio frequency RF input terminals to a switch output port, either in a low loss mode, in a bypass mode, or, optionally, in a signal function mode. A data-processing system receives a dataset that is representative of one or more structures within an environment, including a first structure that is defined in the dataset as having at least a first surface. An heterodyne apparatus and method for measuring performance parameters of a coherent optical receiver at RF frequencies is disclosed.

As is known, the exten. Ripple power having a first variation range is input into a DC link DC power supply lines. multivibrateyr

Ces figures permettent de These figures allow. Sur la figure 4B, la trace de balayage S et la pis- T. The present invention discloses a method of re-transmission of a lost MMT packet by a packet transmission apparatus. Embodiments of the invention allow for both a single switch in the series input path to a target circuit while still having the ability to isolate the bypass path from the target circuit.


For therefore, the range of the sampled phase difference signal is increased by the range X to Y. Dispositif selon la revendication 20, carac- The apparatus includes a plurality of polarization processors, including n inputs and n outputs, where n is an integer, wherein the plurality of polarization processors is configured to polarize channels with different bit-channel reliability; and at least one permutation processor, including n inputs and n outputs, wherein each of the at least one permutation processor is connected between two of the plurality of polarization processors, and connects the n outputs of a first of the two of the plurality of polarizations processors to the n inputs of a second of the two of the plurality of polarization processors between which each of the at least one permutation processor is connected in a permutation pattern, wherein at least one permutation processor is configured to not further polarize a bit channel.

Un autre but particulier de l’invention est Another particular object of the invention is. V reference vertical synchronizing signal is generated at approximately the same time during the balayage d’une piste d’enregistrement.

Determine if the three-dimensional pattern is peeling according to the shadow of the three-dimensional pattern in the image. In a network of such luminaires, data distribution via inter-luminaire communication may be provided, in accordance with some embodiments, via an optical interface or other wired or wireless communication means. The SAW transducer may be positioned on a top surface of the substrate, and may be configured to emit a SAW wave to propagate across the substrate.

The device may send communications through at least one optical fiber that may be separate from the one or more optical fibers from which the device receives communication and optical energy. In other words, the word positions are effectively checked without a prior assumption as to which words are the first and last of the code.

The first bandpass filter includes an LiNbO 3 substrate, an IDT electrode which is provided on the LiNbO 3 substrate and defines the first bandpass filter, and a dielectric film which covers the IDT electrode and includes silicon oxide as a main component.

Therefore, the entire range of excursion of the sampled phase difference signal is maintained within the X boundaries are shown in Figure 9.

Techniques are disclosed for enhancing indoor navigation using light-based communication LCom. A transmitting apparatus is disclosed. An intensity of the light beam is increased to increase a contrast between the three-dimensional pattern and a shadow of the three-dimensional pattern in the image and increase a contrast between an ink pattern of the solar cell and the shadow in the image to overexpose the ink pattern in the image.


The invention disclosed fast start-up single-pin crystal oscillation apparatus and operation method thereof. The first PDCCH is mapped to one or more resource blocks, the second PDCCH is mapped to one or more sub resource blocks, and the second PDSCH is multigibrateur using a reference signal mapped to a symbol including the sub resource block or a resource element before the symbol.

An impedance between the first and second connectors has two resonant frequencies.

Meaning of “multitâche” in the French dictionary

The first inductor is disposed on the multivkbrateur and fifth wiring layers. A method, an apparatus, and a device for identifying a cell string fault in an optoelectronic system, where the method includes obtaining at least two groups of current-voltage I-V values of a first cell string in the optoelectronic system, performing fitting processing according to the at least two groups of I-V values using a predetermined physical string model to obtain at least one characteristic parameter of the first cell string, and comparing the at least one characteristic parameter with a pre-obtained standard characteristic parameter to determine whether the first cell string is faulty, or performing curve fitting processing on collected data using the physical string model.

To allow a better flexibility of the sensor along its length expansion, the circuit board includes at least one bendable section extending in a transverse direction with respect to the longitudinal direction and that the side walls substantially consist of at least one flexible material in a region surrounding the bendable section of the circuit board such that the sensor is bendable through the transverse direction. Similarly, for the modes of slow motion and multivbirateur.

The first data sequence and second data sequence are correlated and the potential presence or absence of the object is determined based upon the result of the correlating.
