摘要： Disclosed herein are methods and systems for efficiently retrieving data from an at least partially encrypted table based record using secure Multi-Party Computation (MPC). A query received to retrieve data from a table based record comprising data items arranged in rows and columns may include a queried data item (key) which potentially matches one or more encrypted data items contained in one or more of the columns. The computing nodes, each having a respective one of a plurality of shares of a one-hot representation of each of the encrypted data items engage in the MPC session to match between a one-hot representation of the queried data item and the one-hot representation of each encrypted data item and output each matching row. The match is based on multiplying, in each encrypted data item's one-hot representation, only bits identified as hot in the queried data item's one-hot representation.

摘要： A kit includes at least one facemask configured to cover a respective user's mouth and nose. The facemask contains at least one layer impregnated with a first chemical. When the facemask covers the respective user's mouth and nose, airborne particles of the first chemical are released from the at least one layer through the user's breathing. A sensor is configured to measure airborne concentration of the first chemical. A processing circuitry is configured to receive outputs of the sensor, to calculate a change in airborne concentration of the first chemical, and to issue a notification when the airborne concentration of the first chemical increases at above a predetermined rate.

摘要： A method of adapting a display comprises receiving a sequence of a plurality of facial images of a face of at least one user located in front of a display; analyzing the plurality of facial images to detect a hand to face gesture of the user; and updating, according to the hand to face gesture, a dataset documenting a plurality of facial touch event frequencies of a plurality of facial touch events in a plurality of facial locations. Each of the plurality of facial touch events is prompted by one of a plurality of previously captured hand to face gestures of the user. The method further comprises, based on the plurality of facial touch event frequencies, generating a presentation on the display. In response to detection of an impending facial touch, a destruction event may be depicted. A presentation may be also generated showing scoring of multiple persons.

摘要： Presented herein are systems and methods for detecting a boundary line crossing based on Round Trip Time (RTT) measured for wireless signals transmitted between and initiator wireless transceiver and a responder wireless transceiver deployed to form a straight boundary line. The initiator wireless transceiver transmits wireless probe signal(s) to the responder wireless transceiver, receives a wireless response signal transmitted by the responder wireless transceiver in response to the wireless probe signal(s), calculates an RTT combining a travel time of the wireless probe signal(s) and the travel time of the wireless response signal(s), compares the RTT to a reference RTT computed for a wireless probe signal and a corresponding wireless response signal transmitted in a clear straight transmission path while the boundary line is clear of obstacles and determines whether an object is blocking the straight transmission path based on a deviation of the RTT from the reference RTT.
