A method of writing data on magnetic stripe of a smart card by imposing a magnetic field of a given polarity on each selected segment of the magnetic stripe, such that data on the magnetic stripe can be read by a magnetic card reader and interpreted as digital bits. The method includes providing a multi-dimensional conductor array placed proximate to the magnetic stripe, the number of conductors in the array is considerably smaller than the number of segments, and each segment is associated with two or more conductors. The method further includes providing current drivers for sending currents in a controlled direction through the conductor array. The system further includes sending currents, using said current drivers, through conductors of the array, such that for each one of the selected segment composite currents flowing through its associated two conductors overcome the coersivity of the segment on the magnetic stripe.

The system and method described herein may identify one or more virtual desktop extensions available in a cloud computing environment and launch virtual machine instances to host the available virtual desktop extensions in the cloud. For example, a virtual desktop extension manager may receive a virtual desktop extension request from a client desktop and determine whether authentication credentials for the client desktop indicate that the client desktop has access to the requested virtual desktop extension. In response to authenticating the client desktop, the virtual desktop extension manager may then launch a virtual machine instance to host the virtual desktop extension in the cloud and provide the client desktop with information for locally controlling the virtual desktop extension remotely hosted in the cloud.

Methods and systems for transmitting compressed audio / video data streams across conventional networks or channels in real time. Each system employs the Adaptive Rate Control (ARC) technique that is based on the detection of defective packets and other influencing factors such as overall system performance, usage model and channel characteristics. To control data stream congestions in the channel and maintain the visual display quality above a certain level, the present invention exploits the human visual perception and adaptability to changing visual conditions. The ARC technique relies on the client's capacity for calculating the quality of video packets received from a server and sending information of a desired transmission rate to the server. This approach simplifies the hardware and software implementation complexity otherwise imposed on the server and reduces the overall design cost by shifting the burden of monitoring bandwidth and transmission control from the server to the client.

The system comprises a refuse target identification unit, a refuse sorting control unit, a mechanical arm and a sampling camera which is mounted at the fixed position of a conveying belt for conveying household refuse; the sampling camera shoots the household refuse on the conveying belt in real time and transmits obtained optical images to the refuse target identification unit; the refuse target identification unit receives the optical images in real time and displays the images, according to the characteristics of presorted target refuse, the optical images are treated, targets in the images are identified, and target posture information frames are obtained, and are input into the refuse sorting control unit; and the refuse sorting control unit judges whether a target enters the working section of the leisure mechanical arm or not according to the input target posture information frames and the opposite position of the mechanical arm and the conveying belt, the posture information of the target entering the working section of the mechanical arm is converted into a mechanical arm coordinate system and sent to the corresponding mechanical arm, and the corresponding mechanical arm is controlled to grab the corresponding target.

The present invention provides a method and apparatus for packet forwarding within a switch controller. In addition to unicast and broadcast forwarding, the method and apparatus can also analyze and forward IP multicast packets without the need of a CPU and a separate multicast address table, thereby enabling IP multicasting for the switch controller. Wherein, specific packet parsing and updating rules are used to analyze IP multicast control packets, and a multicast router or an address table is updated based on the analyzing result. IP multicast packets is then forwarded according to the updated tables. Moreover, with an extra flag bit set in each address table entry, unicast and multicast forwarding can share the same address table.
