A multilayer ceramic capacitor includes a rectangular dielectric body having ceramic layers and multiple first internal electrodes and second internal electrodes alternatively arranged in between each two adjacent ceramic layers and respectively terminating in a respective contact in such a manner that the contacts of the first internal electrodes and the contacts of the second internal electrodes are respectively disposed at two diagonal corners of the dielectric body, and multiple terminal electrodes respectively bonded to the two diagonal corners of the dielectric body and respectively electrically connected with the contacts of the first internal electrodes and the contacts of the second internal electrodes. By means of arranging the terminal electrodes on the two diagonal corners to extend the electrode pitch, the multilayer ceramic capacitor prevents an electric arc effect or electrical fire caused by a surge voltage, eliminating the risk of a short circuit or other accidental events.

For a transmission system in which (a) a received sequence of symbols is processed by an inner decoder followed by an outer decoder and (b) the inner decoder is capable of providing to the outer decoder more than one output sequence corresponding to the received sequence, the decoded sequence released by the outer decoder is screened for errors undetected by the outer decoder, if a predetermined criterion is satisfied.

The present invention relates to a motor device utilizing magnetic force to drive a rotor. The motor device includes a main body, a rotor and a controlling unit. The main body has two openings and an internal chamber. The rotor is magnetic and swingably disposed in the chamber between the two openings. The controlling unit is disposed on outer side of the main body to apply a magnetic force to the rotor for driving the rotor to at least rotate. The rotor is a column body with a certain length. The rotor has a profile corresponding to a configuration of a peripheral wall of the chamber. The outer face of the rotor is formed with at least one spiral groove to define at least one spiral stripe. The rotor is magnetically driven to drive a fluid to flow from one opening to the other opening.

The invention provides optimal complementary punctured convolutional codes for coding information bits in a communication system. In an illustrative embodiment, an optimal pair of complementary punctured codes is selected from a set of potential code pairs. The set of potential code pairs includes all non-catastrophic complementary punctured code pairs which combine to produce to a specified full-bandwidth code, and thus includes both equivalent and non-equivalent complementary codes. The optimal code pair may be selected, for example, as the pair of equivalent or non-equivalent codes which has the best free Hamming distance and minimum information error weight of all the pairs in the set. In addition, the invention provides both rate-compatible and rate-incompatible codes suitable for use in providing unequal error protection (UEP) for different classes of information bits. The invention further provides optimal bit assignment techniques for use in digital audio broadcasting or other applications in which digital information is transmitted on subcarriers in both an upper and a lower sideband of an analog carrier.
摘要:
The likelihood of significant errors in a decoded sequence is determined based on at least one criterion that is both extrinsic and intrinsic to the decoded sequence. In particular, this determination is preferably made by comparing a signal corresponding to the decoded sequence with a so-called error mitigation signal.

A pump unit for magnetically driving an article, including a main body, an article and a coil. The main body has an internal chamber. The article has a certain length and a configuration corresponding to a shape of the chamber. The article is reciprocally movably positioned in the chamber. The coil is wound around the main body and connected with a circuit. The circuit provides a current for the coil so as to drive the article to reciprocally move. The chamber of the main body communicates with two open ends of the main body. The pump unit further includes a first pair of one-way valve sections and a second pair of one-way valve sections. The first and second pairs of one-way valve sections are respectively disposed at two ends of the main body. When the article is reciprocally moved, a fluid can be only driven by the article to flow from a first position to a second position.

A system, method, and product are provided to (1) embed a watermark signal into a host signal, thereby generating a composite signal, (2) optionally enable the composite signal to be transmitted over a communication channel, and (3) optionally extract the watermark signal from the transmitted composite signal. In one embodiment, the invention is a method for watermarking a host signal with a watermark signal. The watermark signal is made up of watermark-signal components, each having one of two or more watermark-signal values. The host signal is made up of host-signal components, each having one of two or more host-signal values. The method includes: (1) generating two or more embedding generators, each corresponding to a single watermark-signal value of a co-processed group of one or more watermark-signal components; (2) having each embedding generator generate two or more embedding values, the total of which is referred to as an original embedding-value set such that at least one embedding value generated by one embedding generator is different than any embedding value generated by another embedding generator; and (3) setting a host-signal value of one or more selected host-signal components to an embedding value of a particular embedding generator, thereby forming a composite-signal value, such that the particular embedding generator corresponds to the watermark-signal value of the co-processed group of watermark-signal components, and such that the embedding value of the particular embedding generator is selected based on its proximity to the host-signal value.

摘要:
In a system for simulcasting digitally modulated and analog FM signals over the same FM frequency band, the effect of the analog FM signal on the digitally modulated signal in the simulcast is calculated and canceled from the latter signal before its transmission. As a result, the digital transmission is free from interference from the analog FM signal. Moreover, the digital transmission is achieved by adaptively inserting a time varying number of carriers modulated by digital data into the FM band. The carriers are selected frame by frame to control their interference with the analog FM signal. In accordance with the invention, the carriers are selected in a predetermined order, and in a preferred embodiment grouped contiguously with one another in the FM band. As a result, the rate of control information required to identify the inserted carriers to a receiver is advantageously low.
