Abstract: A method of verifying the authenticity of goods includes generating one or more random codes and storing the one or more random codes in a database. The goods are then marked with one of the generated random codes such that each of the goods contain their own unique random code. Upon field checking and inventory of marked goods and comparing the codes on the market goods to codes within the database, the authenticity of goods may be verified. Also, a system for verifying the authenticity of goods includes a database containing a plurality of unique random codes and an indication whether each of the unique random codes has been read, and a code reader or scanner for reading the code affixed to a good. The system further includes a computer apparatus or other electrical mechanism for comparing a read code to the unique random codes contained within the database such that upon comparison the comparing means indicates whether the read code is valid and if valid, whether it has been read previously on another good, thereby indicating the good's authenticity.

Title: Variable pitch fan
Inventor: MCCALLUM JONATHAN E
IPC: F04D29/06
Filed: 2000-06-21
Abstract: A variable pitch fan in which the pitch of the fan blades is varied under control of a controller according to the speed of the fan. The controller is programmed to respond to increased fan speed by decreasing pitch of the fan blades. The variable pitch fan has a piston extending axially from a main shaft, about which main shaft a fan blade hub rotates. A pitch shifter is mounted on a cylinder, which itself is mounted on the piston. The pitch shifter is actuated by hydraulic fluid supplied through the main shaft to the cylinder. The piston is preferably axially stationary in relation to the main shaft. The cylinder is secured against rotational movement by cooperating out of round surfaces. Grease for the pitch shifter is supplied through the guide pin. One guide pin may be used for grease supply, while another may be used for excess grease return. Cooling of a pitch shifter may be accomplished using a heat sink mounted within the fan hub, preferably in a fan configuration, to conduct heat away from the cylinder into air rotating within the fan hub. Counterweights are mounted on each fan blade of a variable pitch fan, preferably hydraulically actuated, in a position which generates a torque opposite in direction to torque generated by the fan blades. The counterweights may be overbalanced, underbalanced, or balanced.

Title: A method for maintaining a communication link in wireless network groups
Inventor: PITTAMPALLI ESHWAR
IPC: H04L12/56
Filed: 2000-07-25
Abstract: Disclosed herein is a method and apparatus for maintaining communication between a dependent and a communications network when the dependent is outside a coverage area associated with its master using a controller and a communications network. In one embodiment, when the dependent is in a piconet, the dependent is within communication range of its master using a communication channel on frequency band f band(1). When the dependent moves outside the piconet, the dependent should be within communication range of the controller and, thus, switches to another communication channel within frequency band f band(1) such that it may communicate with the controller. When the dependent moves outside the communication range of the controller, the dependent should be within communication range of a communications network or a base station and, thus, switches to a communication channel within another frequency band f band(2).

Title: Derivation of equivalent bandwith of an information flow
Inventor: SABRY MARTIN
IPC: H04L12/56
Filed: 2000-07-27
Abstract: A connection admission controller determines whether to admit the requested connection according to whether admission would cause a bandwidth used to exceed a maximum bandwidth allowed. For determining the bandwidth used, an aggregate equivalent bandwidth of all connections is determined by determining a static approximation and a flow approximation, the flow approximation having a non-linear relationship to the number of connections. Using a non linear relationship enables the equivalent available capacity for a number of connections to be determined more accurately with less computational resources

Title: Lignin based colloidal compositions
Inventor: LIANG ZHI-ZHONG
IPC: C08L97/00
Filed: 1999-02-22
Abstract: A lignin based colloidal dispersion into lubricating oil or bitumen is prepared from black liquor residue. In one process, in the first step, the black liquor is converted from its aqueous colloidal system to an anhydrous colloidal dispersion in a re-refined lubricating oil medium in which a surfactant, such as DDBSA (dodecylbenzene sulfuric acid), is used to promote the colloidal dispersion. In second step, bitumen is mixed with the product obtained from said first step. In another process, bitumen first is treated with an inorganic acid, such as sulfuric acid, at elevated temperature. The alkaline black liquor is then added slowly to the acid-treated bitumen under agitation for de-watering at a controlled rate to form a stable, substantially anhydrous, colloidal dispersion in the bitumen.
