Abstract: The present disclosure includes systems and/or methods for receiving historical trading data associated with previously executed trade transactions for a financial instrument by a plurality of candidate invitee users. Trading intentions are received from the candidate invitee users and a score representative of a likelihood of successfully trading the financial instrument is modelled for each candidate invitee user based on inputting into a machine learning model the trading intentions and the historical trading data of each candidate invitee user.

Abstract: Computer-implemented methods and computer systems for an electronic transaction platform that enables the buying and/or selling of securities by users. The methods and systems relate to controlling communication of information during an electronic communication session for trading a financial instrument between an initiating user and one or more invitee users with the assistance of a dealer user or other intermediate entity. When a dealer with whom the initiating user has a relationship does not have a relationship with invitee users that may desire to trade for the security, a second dealer can be included in the electronic communication session, where the second dealer has a relationship with such invitee users. Various levels of participation are available for each user and correspond to what information each user is provided during the electronic communication session.

Abstract: Operation of a cutting mechanism provides an annular gasket or washer from a suitable solid gasket or washer material. The cutting mechanism includes a body defining a passage with an opening and a cutting head. The cutting head translationally retracts into the passage through the opening and projects from the passage through the opening along a longitudinal axis of the mechanism. The cutting head carries multiple cutters and can be selectively rotated about the axis when projecting through the opening from the passage. The position of each of the cutters is adjustable along a radial range of distances from the axis to correspondingly set an inner diameter and an outer diameter of the gasket or washer.

Abstract: A smoke alarm device has an ASIC (1) with an integrated photo detector (3) and control circuit. The photo detector output is compared every ten seconds with an alarm threshold level in a comparator circuit (10), with a sensitivity-decrease threshold in a comparator circuit (11), and with a sensitivity-increase threshold in a comparator circuit (12). A logic block (2) causes sensitivity to be increased or decreased in which decreases take place at intervals of six hours and increases take place after 40 secs. The logic block (2) provides for least sensitivity at power-up with rapid increases to the appropriate level according to the level of back-scatter caused by dust contamination. The logic block (2) maintains a high signal on an interconnect terminal (9) for four seconds after a test button (7) is pressed so that a maintenance person can hear remote interconnected devices after the local device has stopped sounding.
