Title: A dental floss device
Inventor: DOUGAN MICHAEL
IPC: A61C15/04
Filed: 2002-11-22
Granted: 2010-11-02
Abstract: A dental floss device (1) comprises a handle (2) having a head piece (3) and a disposable holder (4) for a length of dental floss (5). The holder (4) comprises a base portion (20) and a pair of spaced-apart jaws (21) extending from the base and which extend to embrace the head piece (3) of the handle (2) when the holder (4) is in a correct alignment configuration with respect to the handle (2). The device has an interlock which ensures that the holder (4) can be interengaged with the head piece (3) only when the holder (4) is correctly aligned with the head piece (3). The interlock comprises a head interlock part provided by interlock grooves (10) and a holder interlock part provided by corresponding interlock tongues (11).  There are two interlock grooves (10) and corresponding interlock tongues (11) which slidably interengage when the holder (4) is correctly aligned with the head piece (3). If the holder (4) is turned so that it is not correctly aligned with the head piece (3), the interlock tongues (11) of the holder (4) prevent engagement of the holder (4) with the head piece (3).  Thus there is no risk that a user will incorrectly align and engage the dental floss holder with the head piece (3).

Abstract: The present invention provides cell fusogenic vectors having replicative ability, whose protease-dependent tropism has been modified. M gene-deficient viral vectors encoding modified F  proteins, in which the cleavage site of the F protein of paramyxovirus is modified to be cleaved by different proteases, were produced. In cells transfected with these vectors, the genomic RNA present in the vectors is replicated, and cell fusogenic infection spreads to neighboring cells depending on the presence of other proteases;  however, no viral particles are released. The vectors of this invention, encoding the F proteins which are cleaved by proteases whose activity is enhanced in cancer, show cancer growth suppressive effect in vivo.

Abstract: The present invention is a system and method for restructuring a group of pictures in such a manner as to provide for random access into the group of pictures without substantially degrading the quality of service for the video content. When encoding a current picture if the current picture is an I picture, the current picture is encoded utilizing intra coding. If the current picture is not an I picture, and is not referenced by future pictures, the current picture is compressed using an arbitrary number of pictures in the past as a reference.  If the current picture is not an I picture, and the current picture is not referenced by future pictures, the picture is compressed and the number of reference pictures in the past are limited so that picture prior to the last I picture are not used as a reference. This process continues until the conclusion of the group of pictures.

Abstract: A multiple-input multiple-output (MIMO) system can transmit on multiple antennas simultaneously and receive on multiple antennas simultaneously.  Unfortunately, because a legacy 802.11a/g device is not able to decode multiple data streams, such a legacy device may "stomp" on a MIMO packet by transmitting before the transmission of the MIMO packet is complete.  Therefore, MIMO systems and methods are provided herein to allow legacy devices to decode the length of a MIMO packet and to restrain from transmitting during that period. These MIMO systems and methods are optimized for efficient transmission of MIMO packets.
