Abstract: The invention relates to an adaptive method of extracting at least of desired electro magnetic wave signals, sound wave signals (40, 42), and any other signals from a mixture of signals (40, 42, 44, 46) and suppressing noise and interfering signals to produce enhanced signals (50) corresponding to desired (10) signals, and an apparatus (70) therefore. It relies on the concept of at least one of an attenuation of input signals in each sub-band for signals in such a manner that all desired (10) signals are attenuated less than noise or interfering source signals, and/or an amplification of input signals in each sub-band for source signals in such a manner that all desired (10) signals are amplified, and that they are amplified more than the noise and interfering signals.

Abstract: A method for retransmitting a multicast frame in a wireless network and a method for determining whether or not a received multicast frame is a duplicated frame are disclosed. In determining whether or not the received multicast frame is the same duplicated frame as a previously received multicast frame, a receiver address value and a sequence number of the multicast frame may be used. When fragmentation of a multicast frame is allowed, the value of a fragment number of the multicast frame may be also used, and if it includes a traffic ID, the value of the traffic ID can be also used for determining whether or not the multicast frame is a duplicated frame. If a multicast frame is transmitted in a wireless mesh network, it is determined whether or not the multicast frame is a duplicated one by using a mesh source address, a mesh destination address, and a sequence number. The fragment number and/or the traffic ID may be also used in the determining step as necessary.

Abstract: Disclosed herein is a control method for a Digital Video Recorder (DVR). In the method, a protocol script map table, including command packet information and management information for parsing the command packet information, is newly defined. Whenever a camera using a new protocol is added to the DVR system, a script table for the new protocol is prepared based on the newly defined table, and is copied to a predetermined area of system memory via a data port, such as a Universal Serial Bus (USB) port, and a running main application creates a command packet for controlling the newly connected camera with reference to the prepared script table. Thus, a surveillance camera can be added to a digital video recording system without interrupting a surveillance function.

Abstract: In a single screw compressor, gates (51) of gate rotors (50) are to be engaged with spiral grooves (41) of a screw rotor (40). In each spiral groove (41) of the screw rotor (40), an area extending from a start point of the spiral groove (41) to a position in a compression stroke is a suction-side portion (45), and the remaining portion (portion up to a terminal point of the spiral groove (41)) is a discharge-side portion (46). In the discharge-side portion (46), a clearance between a wall surface (42, 43, 44) therein and the gate (51) is substantially “0 (zero).” A clearance between the wall surface (42, 43, 44) in the suction-side portion (45) and the gate (51) is wider than that between the wall surface (42, 43, 44) in the discharge-side portion (46) and the gate (51), and is gradually narrowed from the start point toward the terminal point in the spiral groove (41).
