Title: Method for trading customer attention for advertisement
Inventor: GOLDHABER A NATHANIEL
IPC: G06Q30/02
Filed: 1996-12-11
Abstract: The present invention provides a new approach for distributing advertising and other information over a computer network. Attention brokerage is the business of buying and selling (brokering) the "attention" of consumers. It can be used to provide direct, immediate payment to a consumer for paying attention to an advertisement or other information. Payment mechanisms may include crediting an account or transferring digital cash directly to the consumer's desktop.  Orthogonal sponsorship breaks the link between an advertisement and program content, allowing advertisers to explicitly delineate their target audience and offer some form of compensation directly to those viewers willing to view ads in compensation for the viewer's time and attention. This compensation may be used directly or indirectly to compensate the owners of content or may be used for other purposes. The link between the ad and the appropriate viewers is provided by reference to a data base of digitally stored demographic profiles of potential users. Such ads may be viewed as "negatively priced"  information because consumers are paid for their attention to the information.  Competing advertisers may "bid" for the attention of consumers using automatic electronic systems, e.g. "an auction" protocol. Private profiles may be maintained for different consumers and consumer information may be released only based on consumer permission. Consumers may be compensated for allowing their information to be released. Information can be routed based on demographics. A special icon or other symbol displayed on a computer screen may represent compensation and allow users to choose whether they will view an ad or other information and receive associated compensation. These concepts can be generalized to provide an electronic trading house where buyers and sellers can actively find each other and negotiate transactions. Software agents can actively seek out interested consumers or interested purveyors of information.

Title: Security system alarm panel
Inventor: PILDNER REINHART KARL
IPC: H04M11/00
Filed: 1998-07-17
Abstract: The invention provides an alarm panel connected to a telephone line. The alarm panel comprises a microprocessor connected to a circuit which operates in two states: passive and active. In the passive state, the alarm panel monitors the line for a ring signal and tests the integrity of the telephone line. In the active state, the alarm panel seizes the telephone line and provides full bi-directional communication with a receiver through the telephone line. The circuit is designed such that the individual subcircuits for each state operate independently of each other and can be modified to meet various regulatory requirements without affecting the other circuits. The circuit draws low current in the passive state. Finally, the circuit is separated from the microprocessor using only 2 or 3 optocouplers.

Title: Encrypted postage indicia printing for mailer inserting systems
Inventor: BATOR FELIKS
IPC: G07B17/00
Filed: 1998-07-21
Abstract: A post production processing application receives and manipulates document print images, in particular to integrate postage printing and accounting into the document finishing, without the need for a specialized postage printing system. The post production processing application may run on a main frame, together with the application(s) that generate the document print images, or on some other computer platform. The post production processing application calculates postage for each document and interacts with a postage metering functionality to obtain digital tokens. Each token includes an encrypted cipher for use in validating applied postage indicia. The mail processing system uses the tokens to generate postage indicias, containing the ciphers, during the subsequent document printing and finishing processes. The meter functionality may reside in software (e.g. as part of the post production processing application), in a meter device associated with and connected to the platform that runs the post production processing application or in a remote data center in communication with that platform. The mail processing system may print the indicias on the documents or on envelopes that will carry the documents.

Filed: 1997-05-07
Abstract: The present invention reveals an in vitro procedure by which an homogeneous population of multipotential precursor cells from mammalian embryonic neuroepithelium (CNS stem cells) can be expanded up to 109 fold in culture while maintaining their multipotential capacity to differentiate into neurons, oligodendrocytes, and astrocytes. Chemically defined conditions are presented that enable a large number of neurons, up to 50 % of the expanded cells, to be derived from the stem cells. In addition, four factors -- PDGF, CNTF, LIF and T3 -- have been identified, which, individually, generate significantly higher proportion of neurons, astrocytes, or oligodendrocytes. These defined procedures permit a large-scale preparation of the mammalian CNS stem cells, neurons, astrocytes, and oligodendrocytes under chemically defined conditions with efficiency and control. The present invention also reveals in vitro cultures of region-specific, terminally differentiated, mature neurons derived from cultures of mammalian multipotential CNS stem cells and an in vitro procedure by which the differentiated neurons may be generated.
