Abstract: Systems and methods for function argument checking are disclosed. The systems and methods can use declarations and validation instructions based on the declarations. Validation instructions for a function can be generated automatically from a declaration for the function. The validation instructions can be executed in response to invocation of the function. The validation instructions can include instructions for determining whether an input satisfies a condition on a corresponding argument of the function, instructions for identifying a position of the input, and instructions for providing, in response to determining that the input does not satisfy the condition, an indication of the nonsatisfaction of the condition and the position. The condition can specify a datatype or size for the argument or one or more validation functions for checking the argument.

Abstract: A system may obtain an executable code segment of program code. The executable code segment may be associated with an emitter, and the program code, when executed, may be associated with a plurality of execution states. Each execution state, of the plurality of execution states, may correspond to a state of execution at a point in the execution of the program code that causes an event, of the plurality of events. The system may execute the executable code segment. The system may receive, from the emitter and based on executing the executable code segment, a program state corresponding to the particular execution state. The emitter may emit the information based on a particular event caused by executing the executable code segment. The system may collect the program state and information describing the particular event.

Abstract: A child restraint system for use in vehicles comprises a seat portion and a base. The base secures the child restraint system to a vehicle seat with a vehicle restraint such as a seat belt or a LATCH system. The base both engages the vehicle restraint and includes a force-multiplying mechanism for tensioning the vehicle restraint. Tensioning the vehicle restraint secures the base by forcing the base against the vehicle seat. An embodiment of the base includes a platform configured to rest on the vehicle seat, an upright member joined to the platform, and a tensioning device, including a force-multiplying mechanism, for tensioning the vehicle restraint.
