Abstract: A dust collection container, capable of being installed in a vacuum cleaner, includes a case body and a blocking member. The blocking member is disposed in the case body to separate the case body into a dust chamber and a diversion chamber, a suction inlet corresponding to the dust chamber and an exhaust opening corresponding to the diversion chamber are disposed in the case body, and a barrier piece is disposed at the blocking member opposite to the suction inlet, so as to form a slow flow area between the barrier piece and the suction inlet to effectively disperse dirt.

Abstract: A distance measuring device is provided. The distance measuring device includes: a distance sensing unit, for sensing a distance value of a target object; a drive unit, for driving the distance sensing unit to rotate according to a rotation angle; and a compensation unit, for providing a compensation value according to the rotation angle and obtaining an actual distance according to the compensation value and the distance value.

Abstract: A Voice over Internet Protocol (VOIP) system cooperates with a phone and an access point storing default connecting information. The VOIP system includes a transmitting module, a receiving module, a decoding module and a comparing module. The transmitting module is disposed in the phone and transmits numeral information. The receiving module is disposed in the access point and receives the numeral information. The decoding module is disposed in the access point and is electrically connected with the receiving module for converting the numeral information into character information. The comparing module is disposed in the access point and is electrically connected with the decoding module for comparing the character information and the default connecting information so as to determine whether the access point proceeds to connect with the phone or not.
