Abstract: A private information detector for data loss prevention is described.

Abstract: Chat-based systems and methods for data loss prevention are described. In one embodiment, a method includes receiving an enable command from a chat service by a data loss prevention service, scanning data from a data source with the data loss prevention service in response to the enable command to detect private information in the data, generating an alert for the private information by the data loss prevention service, and sending the alert to the chat service to cause the chat service to broadcast a chat alert to a group of users.

Abstract: A crosspoint switch routes signals between its terminals in routing patterns defined by routing data from a host controller. The crosspoint switch includes an array of pass transistors. Each pass transistor, when turned on, provides a signal path interconnecting a separate, unique pair of the switch terminals. The crosspoint switch also includes two static random access memory banks. Each memory bank stores routing data defining a separate routing pattern and produces a separate set of output signals reflecting its stored data. A multiplexer delivers the output signals of a selected one of the memory banks to the switch array for controlling its pass transistors so that the switch array implements the routing pattern defined by the data in the selected memory bank. By loading routing data defining different routing patterns into the two memory banks, a host controller can thereafter quickly make the crosspoint switch alternate between the two routing patterns by toggling the multiplexer's control input.

Abstract: An electronic crossbar switch employs a switch array for selectively routing digital and analog signals between its terminals. A separate port for each terminal provides a path for digital and analog signals flowing in and out of the switch. Each port can be configured to operate with or without tristate buffering under control of a tristate control signal, to optionally latch input or output signals in response to clock and clock enable signals, and to buffer signals passing in or out of the switch terminal with or without an input direction control signal. A set of control inputs are provided in common to all ports, allowing an external host to transmit control signals in parallel to each port. Each port may be programmed to select any of its control inputs as its tristate, clock enable, clocking or direction control signal.

A parallel "key" bus is also provided in common to all ports for conveying a key address from the host controller.

Abstract: A field programmable interconnect device (FPID) selectively routes signals between signal ports in response to commands from a host controller. Each command includes an address and data. The FPID includes an array of switch cells, each interconnecting a separate pair of the ports and each having first and second control signal inputs. When the first and second control signals are both asserted, the switch cell provides a signal path between the pair of the ports it interconnects. The FPID includes first and second sets of memory cells for storing data. Each first memory cell corresponds to a separate one of the switch cells and selectively asserts or deasserts the first control signal input to the corresponding switch cell according to its stored data. Each second memory cell corresponds to a separate group of switch cells and selectively asserts or deasserts the second control signal input to each switch cell of the corresponding group according to its stored data.
