摘要： An error handling apparatus and method, and a computer-readable medium storing a computer program for executing the error handling method are provided. According to the method, in a case where a number of errors in object IP packets that are consecutively detected, each within a first predetermined time since a previous error detection, exceeds a maximum allowable number of errors, communication with a sending node of the erroneous IP packets during a second predetermined time is discontinued. Also, errors can be handled with reference to a cache unit including more than one entry identified by an address of a corresponding erroneous IP packet. Therefore, a network load of a receiving node can be reduced by not transmitting an internet control message protocol (ICMP) packet to a sending node where indiscriminate IP packet manipulations or denial of service (DoS) attacks are suspected during the second predetermined time.

摘要： An apparatus and method for generating a checksum. The checksum generation method includes: determining whether or not an already calculated first checksum value is identical or similar to a second checksum value for which calculation is requested; if it is determined that the values are identical or similar, reading a difference value of the first checksum value and the second checksum value from a database; and by adding the read difference value to the first checksum value, generating the second checksum value. According to the method, when a checksum value identical or similar to an already calculated checksum value is to be calculated, the calculation is not performed again and instead, by adding only the difference value, a new checksum value is generated

摘要： An image stabilizer includes a rotor including a lens assembly, and configured to move perpendicular to an optical axis of light passing through the lens assembly, and a suspension unit configured to support movement of the rotor and to prevent the rotor from moving non-perpendicular to the optical axis of the light passing through the lens assembly. Accordingly, the image stabilizer prevents variance of characteristics of a rotor in a low frequency band according to the position and distortion of phase characteristics in a high frequency band. Therefore, the image stabilizer has consistent operation characteristics regardless of the position, posture, and movement of a person using an image capture device containing the image stabilizer.

摘要： An Internet control message protocol packet generating system includes a field error detecting unit, which detects at least one field error upon reviewing all fields of the Internet protocol packet; and an Internet control message protocol packet generating unit, which records information for the at least one detected field error on the Internet control message protocol packet. The Internet control message protocol packet generating system may further include a field error information storing unit, which sequentially stores information on field errors detected by the field error detecting unit. The Internet control message protocol packet generating unit may generate the Internet control message protocol packet based on field error information stored in the field error information storing unit.
