Abstract: A method of maintaining a network connection is used between an electronic apparatus and a server. The method includes the following steps: (a) sending an Nth test packet to the server, and the Nth test packet requests that the server reply to the electronic apparatus after waiting for an Nth time interval; (b) determining whether a reply for the Nth test package is received; (c) repeating step (a) if the reply for the Nth test packet is received; and calculating a period from the (N?1)th test packet being sent to the reply from the server being received if the reply for the Nth test packet is not received; and (d) sending a keep-alive packet periodically to the server according to the period for maintaining a connection between the electronic apparatus and the server when the electronic apparatus is switched to a standby/sleep mode.

Abstract: An event integrating and displaying method for an electronic apparatus is disclosed. The method includes the follow steps: collecting a plurality of events established by different sources; calculating an event similarity between any two target events of the plurality of events to determine whether the event similarity exceeds a defined value, wherein the event similarity is obtained from calculating a time similarity, a location similarity, and an attendance similarity between the two target events; if the event similarity exceeds the defined value, integrating the two target events into an identical event.

Abstract: The present invention discloses a biochip scanning device including a light source for emitting a light; a rotatable optical grating hologram located at one side of the light source for diffracting the light to form a diffractive light; a sampling stage that can be placed a specimen and can be irradiated with the diffractive light; and a linear charge coupled device (CCD) that can receive a reflective light of the diffractive light via the specimen. With the rotatable optical grating hologram, the light can be uniformly diffracted, and a more correct signal noise ratio is obtained to ensure accuracy of the light signal. In addition, the light can be replaced by a linear light source to effectively improve the scan speed and save the testing time.

Abstract: A multi-purpose scanner that can be integrated into a computer. In one embodiment, the multi-purpose scanner functions as a desktop scanner. It includes a scanning engine and an external housing. The external housing substantially encapsulates the scanning engine to reduce electromagnetic interference to the scanning engine. In another embodiment, the multi-purpose scanner scans with scanning engine mechanically attached to the computer. The scanning engine includes an internal body, a chassis and a positioning assembly. The chassis holds the internal body, and the assembly moves the internal body relative to the chassis. In this embodiment, the scanner extends a part of the internal body out of the chassis in order to scan a medium. In a third embodiment, the multi-purpose scanner functions as a handheld scanner. The scanning engine includes a front-panel unit that is releasably attached to an engine unit.
