摘要： An apparatus for controlling a delay includes a phase locked loop and a delay unit. The phase locked loop generates an oscillation signal having a frequency substantially identical to that of a reference signal. The delay unit includes a delay cell block that outputs delayed signals by delaying the reference signal sequentially by a uniform delay interval. The delay unit controls the delay interval based on a frequency/phase difference between a first input signal and a second input signal of the phase locked loop, and outputs one of the delayed signals as a delayed reference signal. Related methods are also described.

摘要： For clock and data recovery (CDR), a clock processor generates sampling clock signals from original phase-shifted clock signals each having a frequency that ⅛ of a frequency of an input data signal. The sampling clock signals are used to sample the input data signal for generating error signals and reference signals that determine a voltage control signal that indicates a clock frequency of the original clock signals generated by a voltage controlled oscillator (VCO).

摘要： Methods, systems, and apparatus are provided to generate a most probable explanation (MPE) for a Bayesian Network (BN). A first data structure is populated by iterating from the leaves of a junction tree (derived from the BN) to the root and retaining maximum potentials along the way. A second data structure records selective index locations that map into the first data structure. These selective locations correspond to selective maximum potentials housed within the first data structure. All the selective maximum potentials are resolved once a root maximum potential is known for a given problem. The selective maximum potentials form a MPE through the junction tree to reach the result.

摘要： We describe a dual modulus prescaler that may be used in a high frequency PLL. The prescaler comprises a frequency division unit to generate a prescaled signal by dividing a frequency of an input signal by a division ratio and a frequency division ratio controller to determine the division ratio responsive to a count signal and the prescaled signal. The frequency division unit divides a frequency of an input signal by a division ratio of 2N or (2N−1) to output a prescaled signal. The frequency division ratio controller determines a division ratio responsive to a count signal and the prescaled signal.

摘要： A ferroelectric layer is deposited or in close proximity to a ferromagnetic ferrite layer to make a microwave substrate on which conductors can be deposited or placed to make devices. The permittivity of the ferroelectric layer can be changed by applying a voltage and the permeability of the ferromagnetic layer can be changed with a magnetic field. This makes it possible to tune the device characteristics with two different effects taking best advantage of the capabilities of each. A material example is ferromagnetic yttrium-iron-garnet on which is deposited a thin film of ferroelectric barium strontium titanate. To minimize losses, the ferroelectric film should be high quality, but practical yttrium-iron-garnet substrates are polycrystalline so that the use of buffer layers is desirable. At least two methods can be used to deposit the ferroelectric film, pulsed laser deposition and metal-organic chemical liquid deposition. A variety of dual tunable microwave devices can be made with this substrate, including by way of example only, phase shifters, frequency filters, and resonators.

摘要： A magnetic levitation imitation flame device includes a mounting base, a flame member, a positioning bracket, a first magnet, and a second magnet. The positioning bracket is fixed in the mounting base. The first magnet is disposed on the flame member. The flame member is disposed on the positioning bracket and protrudes outwards from the mounting base. The second magnet is fixed at a lower end of the positioning bracket. The first magnet and the second magnet are arranged up and down. Magnetic poles thereof facing each other have same polarity so that the flame member is levitated relative to the positioning bracket under a repulsive force of the first magnet and the second magnet. Thus, the flame member swings with big angle, naturally and realistically, and saves electric energy. In addition, an imitation flame lamp is also provided.

摘要： Technologies are generally described for systems and methods effective to implement particle removal. In one example, a method for at least partially removing particles from a region is generally described. In some examples, the method includes applying an electric field to a material to produce an acoustic wave from the material. The material may have a periodic piezoelectric coefficient. The method may include applying the acoustic wave to the region to produce an agglomeration. The agglomeration may include at least two of the particles. The method may further include at least partially removing the agglomeration from the region.
