the class IOKitUtils method resetIdleTimer.

/**
 * Creates an assertion preventing sleep with a timeout value equal to the
 * idle sleep time. This has the same effect as if a user activity occurred
 * so that the idle timer was reset.
 *
 * @param assertionName the name of the assertion to create.
 * @param assertionId the assertion id if you want to extend the time of an
 *            existing assertion or {@code 0} to create a new assertion.
 * @return The assertionId of the created assertion. This may or may not be
 *         the same as {@code assertionId}.
 * @throws IOKitException If an error occurs during the operation.
