Title: Network management using periodic measurements of indicators
Inventor: KWAK JOSEPH A
IPC: H04L12/28
Filed: 2004-05-13
Abstract: A beacon signal used in data communications, such as the IEEE 802.11, is provided with data extensions. The data extensions permit additional information to be provided by the beacon signal. Periodic beacon requests are made during connection between a wireless transmit/receive unit and an access point (AP) on a WLAN. A Measure¬ment Request field corresponding to a beacon request contains a measurement duration value and channel number for which the request applies. The beacon request permits a scan mode, which includes 'Active Scan' mode, 'Passive Scan' mode and 'Beacon Table' mode.

Granted: 1993-07-19
Abstract: The air outlet device (1) has in a rectangular air duct (10) horizontal and vertical air-conducting lamellae (5, 4) mounted pivotably on its shaft (22). The horizontal lamellae (5) are connected to a common drive which consists of a cylinder/piston unit (11). The cylinder (12) of this drive is connected to a closed tubular container (13) which is filled with a medium capable of flowing and which extends over a major part of the opening cross-section of the air duct (10). When the temperature of the air flowing through the device changes, the cylinder/piston unit, as a result of the expansion of this medium, displaces a drive plate (16), the rack-like toothing (24) of which engages in toothed wheels (23) which are fastened to the end of each horizontal lamella (5). The drive is built into the air outlet device (1) in a compact manner and so as to be immune to faults. The air outlet device makes possible automatic optimum adjustment of the lamellae (5) which determine the upward or downward flow of the air flowing out of the device (1). The inclination of the lamellae (5), which corresponds to a given air temperature, can be adjusted by hand by means of a tool. <IMAGE>

Title: Time stamping for packet system nodes
Inventor: ADELMANN HARRY W
IPC: H04L12/56
Filed: 1987-01-30
Granted: 1990-12-11
Abstract: TIME STAMPING FOR PACKET SYSTEM NODES     Abstract Delay that a packet experiences in a network node is measured by employing a single local time signal in the node, and by separating a time stamp update function into a network node entry time stamp function and a network node exit time stamp function.  The node entry time stamp function is to generate a packet originate time value referenced to the local time signal value upon the packet entering the node.  This packet originate time value is inserted into a packet header time stamp field to be transported through the node. The node exit time stamp function is to generate an updated time stamp value from the packet originate time value from the header time stamp field and the local time signal value upon the packet exiting the node.  The updated time stamp value is inserted into the packet header time stamp field in place of the packet originate time value.

Inventor: O'MARA DION P
IPC: C08J3/12
Filed: 1986-12-12
Granted: 1993-03-30
Abstract: ABSTRACT OF THE DISCLOSURE    A   particulate,   free-flowing   and  rapid  dissolving  polymer composition  is  prepared  by  comminuting  a  high  molecular  weight thermoplastic  or  viscoelastic  polymer  at  a  temperature below its glass  transition  temperature  while  maintaining  the  polymer in an inert  environment.   A finely divided, solid coating agent is mingled with  the  comminuted  polymer while maintaining the polymer particles in  a  cold and inert atmosphere.  The particles of coating agent form a  protective  shell around each polymer particle by tumble mixing the components  while raising the temperature of the mixture.  The polymer composition  finds  use  as  a drag reducing agent; as an anti-misting agent;  to  enhance  the  efficiency  of  oil  skimming  processes and devices; and for the preparation of polymer solutions for other uses.

Title: Battery separator
Inventor: CHOI WAI M
IPC: H01M50/494
Filed: 1987-05-07
Granted: 1991-09-10
Abstract: ABSTRACT     The present invention is a sheet material for use in alkaline batteries as a separator or interseparator. The sheet is formed of about 30 to about 70 percent polyolefin synthetic pulp, from about 15 to about 65 percent alkali resistant inorganic filler and from about 1 to about 35 percent of one or more long fibers, wherein at least some, if not all of the fiber is a water swellable polyvinyl alcohol based fiber and any remaining long fiber is a nonwater swellable fiber. The water swellable fiber during processing of the sheet forms a gel-like network when contacted by water which retains the filler and bonds the remaining materials together. The resulting sheet has increased tensile strength and alkali resistance and is especially useful in automated battery manufacturing processes.

Granted: 1991-07-30
Abstract: ABSTRACT          Needle printing head.           The invention relates to a needle printing head (1) comprising a number of printing units (2). Each printing unit (2) is provided with a spring (9) supporting an armature (6) and a printing needle (10). The armature (6) is included in a magnetic field path comprising both a permanent magnet (4) and an electromagnet (7) provided with a core (8). Each spring (9) has one rigidly fastened end and one freely swinging end. According to prior art needle printing heads, the springs are so fixed that essentially the hole bending takes place in one single point in direct connection to the rigidly fastened end. This puts high requirements upon the spring material and the risk of material fatigue is great. According to the invention the bending of the spring (9) does not take place in one signal point, but it distributed along at least a first length adjacent to the fastening point. This distributed fastening is obtained by means of a supporting means (5.1) disposed on the side of the spring facing the electromagnet between the fastening point and an end of the core of the exciting coil (8) disposed in connection to the armature (6).

Title: Keyboard keys located on computer screen
Inventor: LAPEYRE JAMES M
IPC: G06F3/0487
Filed: 1988-01-05
Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE:    The conventional keyboard is replaced by a virtual keyboard pattern on the computer screen by this invention.  Selection of keystrokes is made by a mouse, or the like, positioning a cursor at a desired key for keyswitch selection.  This manner of selection of pre-formed patterns available from the computer, such as alphanumeric characters and computer commands is particularly advantageous in a computer aided drafting and design system.  Thus, notations and lettering need not be formulated by analog movement of the mouse, but  can be selected digitally from the computer store by keyswitching.  The resulting equipment therefor eliminates the conventional keyboard but not its opera-tional advantages thereby permitting full computer operation with a mouse or the equivalent.  Several features of the invention are provided for more convenient and more rapid operation, such as the replacement of the keyboard arrays as the computer changes modes of operation, and the placement of more frequently used keystrokes on the keyboard arrays for selection by minimized movements of the mouse.
