Abstract: A method may include determining that a non-constant value of a variable corresponding to a variable node of the abstract syntax tree flows into an operator node in the abstract syntax tree. The method may further include adding, to the abstract syntax tree, a check taint node including functionality to: make a taint status determination that the non-constant value is tainted, and return the non-constant value to the operator node. The operator node generates a result value by executing an operator using the non-constant value. The method may further include adding, to the abstract syntax tree, a set taint node that stores, based on the taint status determination, the result value in a second tainted object, and performing, using the abstract syntax tree, a taint analysis of the source code to identify a vulnerability in the source code.

Abstract: To satisfy the application requirement to meet a high data rate and obtain a large coverage in an optical wireless communication system, an optical front-end subsystem (100) is disclosed in the present invention. The optical front-end subsystem (100) comprises a first photodiode (110) with a first active surface area and a second photodiode (120) with a second active surface area, wherein the second active surface area is larger than the first active surface area. Depending on the received signal strength, either the branch with the first photodiode (110) or the branch with the second photodiode (120) is selected to provide an output signal of the optical front-end subsystem (100). Receiver diversity is achieved by making use of the first photodiode to support high speed communication and the second photodiode to support large coverage communication.

Abstract: This invention relates to a power supply system for an optical wireless communication system where a modem (212) is connected to a plurality of transceivers (11). The underlying idea being that the transceivers (11) are powering the modem (212), rather than the modem (212) powering the transceivers (11). To achieve this, a power combiner is provided that can receive power from the transceivers (11). The transceivers (11) power down when no endpoint is detected and use a subset of emitters, in which case the modem (212) can also be switched to a lower power mode.

Abstract: In a multi-cell wireless communication system (100) with at least one optical access point (120) and at least one radio frequency access point (120), more flexibility is provided to an end device (110) in selecting an access point (120) for establishing a data link. Because of the line-of-sight characteristic of an optical link and the limited field of view of an optical receiver, optical cells are typically deployed with a relatively high density and adjacent optical cells may have an overlapping area. This invention discloses a method of an end device (110) for selecting a favorable access point (120) with reduced overhead, even when the end device is located in the overlapping area of two adjacent optical cells.
