Abstract:
A virtual machine monitoring method used in a virtual machine monitoring system is provided. The virtual machine monitoring method includes retrieving a hypercall transmitted from one of a plurality of virtual machines to a hypervisor of a virtual machine monitoring system, wherein the hypercall is used for establishing a channel between a source virtual machine and a target virtual machine. A central control virtual machine ID information in the hypervisor is retrieved. A type of the channel established by the hypercall is determined according to the central control virtual machine ID information and channel-establishing information corresponding to the hypercall. When the channel is a private channel that is not related to a central control virtual machine of the virtual machines, a security module is used to monitor the private channel.

Abstract:
A communication system and a method which can reduce the effect of burst noise. The communication system comprises a controllable oscillator, a mixer, a decision circuit, a comparator, a loop filter, and a controller. The controllable oscillator generates an oscillating signal. The mixer coupled to the controllable receives input data and mixes the input data with the oscillating signal. The decision circuit receives the mixed input data and generates an estimated symbol. The comparator generates a decision error between the estimated symbol and the mixed input data. The loop filter coupled to the controllable oscillator filters the decision error, and generates a filtered decision error, and the controllable oscillator generates the oscillating signal according to the filtered decision error. The controller reduces a bandwidth of the loop filter according to the decision error.
Abstract:
A method and a system for reading radio frequency identification (RFID) tags are provided. The method includes the following steps. First, receive a tag signal from the RFID tag. Recover a data clock rate from the tag signal according to statistics of pulse lengths of the tag signal. Next, determine a frame synchronization point of a data frame following a preamble in the tag signal by a signal correlation between the preamble and a predetermined signal pattern according to the data clock rate. Finally, decode the data frame by using an adaptive Viterbi algorithm on an extended trellis diagram. The extended trellis diagram includes a plurality of nodes and a plurality of branches connecting the nodes. The nodes and the branches are arranged according to the modulation scheme of the data frame and possible variations of the data clock rate.

Abstract:
A high-voltage device structure includes a high-voltage device disposed on a semiconductor substrate. The semiconductor includes an active region and an isolation region, and the high-voltage device is disposed in the active region. The high-voltage device structure includes a source diffusion region of a first conductive type, a drain region of the first conductive type, and a gate longer than the source diffusion region and the drain diffusion region so as to form spare regions on both sides of the gate. The isolation region is outside the active region and surrounds the active region. In the isolation region, an isolation ion implantation region of a second conductive type and an extended ion implantation region are disposed to prevent parasitic current from being generating between the source diffusion region and the drain diffusion region.
Abstract:
An ergonomic inertial positioning system comprises a motion sensor, an angle sensor, and a processor. The motion sensor detects movement of an object. The angle sensor detects angle variation of the heading of the object. The processor determines motion status of the object based on detected data provided by the motion sensor and the angle sensor, and calculates displacement of the object utilizing the detected angle variation thereof based on the motion status.
