A system and method for configuring a device to perform a function, where the device includes a programmable hardware element and one or more fixed hardware resources. A program is stored which represents the function. A hardware configuration program is generated based on the program, specifying a configuration for the programmable hardware element that implements the function, and usage of the fixed hardware resources by the programmable hardware element in performing the function. A deployment program deploys the hardware configuration program onto the programmable hardware element, where, after deployment, the device is operable to perform the function, where the programmable hardware element directly performs a first portion of the function, and the programmable hardware element invokes the fixed hardware resources to perform a second portion of the function. An optional measurement module couples to the device and performs signal conditioning and / or conversion logic on an acquired signal for the device.

A method and apparatus for generating checksum values for data segments retrieved from a data storage device for transfer into a buffer memory, is provided. A checksum list is maintained to contain checksum values, wherein the checksum list includes a plurality of entries corresponding to the data segments stored in the buffer memory, each entry for storing a checksum value for a corresponding data segment stored in the buffer memory. For each data segment retrieved from the storage device: a checksum value is calculated for that data segment using a checksum circuit; an entry in the checksum list corresponding to that data segment is selected; the checksum value is stored in the selected entry in the checksum list; and that data segment is stored in the buffer memory. Preferably, the checksum circuit calculates the checksum for each data segment as that data segment is transferred into the buffer memory.

The present invention is to provide a lamp socket type camera which includes an outer housing, a bulb socket connected to the outer housing and capable of being threadedly and electrically connected to an existing lamp socket for receiving electric power from the lamp socket, a power module received in the receiving space and electrically connected to the bulb socket for converting the electric power received from the bulb socket into a required specification, a control module received in the receiving space and connected to the power module, a wireless transmission module received in the receiving space and connected to the control module, and an image capturing element connected to the power module and the control module respectively for capturing image data from outside of the outer housing and transmitting the image data to the control module which will send the image data out via the wireless transmission module wirelessly.

Systems and methods for error resilient transmission and for random access in video communication systems are provided. The video communication systems are based on single-layer, scalable video, or simulcast video coding with temporal scalability, which may be used in video communication systems. A set of video frames or pictures in a video signal transmission is designated for reliable or guaranteed delivery to receivers using secure or high reliability links, or by retransmission techniques. The reliably-delivered video frames are used as reference pictures for resynchronization of receivers with the transmitted video signal after error incidence and for random access.

In an embodiment, a first debug agent at a first computer receives a packet. The first debug agent adds a debug command and an identifier of the first debug agent to the packet and sends the packet to a receiving computer. A second debug agent at the receiving computer removes the debug command and the identifier of the first debug agent from the packet and sends the packet to a second program that executes at the receiving computer. The second debug agent further executes the debug command, which causes the second program that executes on the receiving computer to halt execution at a breakpoint or address watch memory location. The second debug agent sends the state of the second program to the first debug agent, which presents, at the first computer, the state and a listing of the second program.

Wrongful authentication process is prevented. A passive entry authenticating section compares an identification signal sent from a portable unit with an identification signal previously stored in a storage section. A biometrics authenticating section compares the biometrics information of a user inputted through a sensor section with the biometrics information registered in a biometrics database. A control section authenticates an authorized user when there is agreement in both the identification-signal comparison result and the biometrics-information comparison result, and controls a lock system to unlock the door lock of the automobile.

Embodiments of the invention disclose a two-dimensional code distortion correction method and apparatus. The method comprises the steps of obtaining a two-dimensional code image; according to the two-dimensional code image, calculating distorted image coordinates of four vertexes of the two-dimensional code image; according to a preset length-width ratio of a two-dimensional code, calculating undistorted image coordinates corresponding to the four vertexes of the two-dimensional code image; according to the distorted image coordinates and the undistorted image coordinates, establishing a linear equation set; according to the linear equation set, calculating unknown parameters in a homography matrix; according to a calculation result, correcting the two-dimensional code image; and outputting a rectangular image containing the corrected two-dimensional code image. The method and the apparatus can be used for distortion correction of different types of two-dimensional codes; the use convenience and the diversity of application scenes are remarkably improved; the rotation-free corrected two-dimensional code image can be quickly obtained; the correction process is simple and quick; thefinally output corrected two-dimensional code image is a rectangular region image only containing two-dimensional code region information; subsequent decoding is facilitated; and the decoding efficiency can be improved.

A method in a communication system in the present disclosure includes: receiving a first access from the information apparatus which starts a first application for a telephone conversation function; transmitting an identifier and a confirmation destination address to the information apparatus in response to the first access; receiving an instruction to the information apparatus from the information processing apparatus; receiving a second access using the confirmation destination address from the information apparatus; transmitting the instruction to the information apparatus in response to the second access; and when it is judged that the instruction instructs the information apparatus to start the second application for providing a camera function, causing the information apparatus to continue the telephone conversation process, to start the second application without involving a user operation, receiving image information captured using the camera function from the information apparatus, and forwarding the image information to the information processing apparatus.
